2D engine that uses Flash Platform classes? I want to develop a 2D game for Android, but, I want to use Flash Platform's framework APIs, ex Sprite, Shape, Graphics, Bitmap .. etc as I have already wrote my game in AS3 .. Is there a 2D engine for Android that uses Flash Platform's framework APIs? If not, does Unity use Flash Platform's framework APIs? I know that I can Adobe AIR to port the game to android, but, I want it a native code based to avoid Adobe AIR player as a requirement .. Any guidance?

How do I calculate UV space from world space in the fragment shader? In my vertex shader I have calculated the world space o.worldSpacePosition mul(unity ObjectToWorld, vertIn.vertex) How do I convert that world space into uv space coordinates in my fragment shader? float4 frag(VertexShaderOutput i) COLOR SV Target0 float2 uv i.worldSpacePosition ??? I have tried float4 mvp UNITY MATRIX MVP 3 float2 uv mvp.xy p.w but that does not appear to work as the uv is always (0, 0) EDIT I am drawing a mesh on the screen in world space coordinates which needs to lookup into a screen space texture The way I am currently solving this is by calculating the uvs for each vertex of the mesh using the following calculation camera.WorldToViewportPoint(vertices i ) Unity uses normalised coordinates for the viewport 0,1 rather than 1,1 . This works fine but I wasn't sure of the behaviour if part of the polygon is off the screen. I presume I should clamp the uv? Screen space might not be the correct term for the uv coordinates. Perhaps texture space is a more appropriate term?

Unity2D Floor tiles moved or missing I'm following the 2D Roguelike tutorial, which can be seen here. I don't want to get fancy, just follow the existing steps. I've reached the part where all it's supposed to do is draw the playfield. But it looks like this and I don't know why. Some of the floor tiles are appearing beyod the outer wall, and others are missing (or maybe they're stacked on top of other tiles). (EDIT I discovered that the "missing" tiles are because I had the sprites in the wrong layer, and fixed them. I still have several appearing to the left of the outer wall, though.) I tried to debug it in Visual Studio. The plan was to step through it line by line to see how the tiles are put down, but the debugger doesn't show the playfield until the whole thing is complete.

Why Godot over Cryengine, UE4, Armory3d or Unity3d? Godot have a low performance in linux systems and lack of functionalities? This appear not been in account when peoples vote for him over other engines and i wonther whi. I know it is under MIT lisence, but the others engines have a very permisive licences and in some cases they help you with funding for your games. I ask this because i have maded survey on google plus about a selection of engines, and people still bote for godot over other engines. I want to select an engine for my future games, and when i compared, godot's not get a good place.

When creating an FPS style game, how should the iron sights be setup? I am working on creating an FPS style game for learning purposes. I previously was using self created animations for aiming down the iron sights of a gun. The animation would play when you zoom to iron sights and it would hold it there as long as you have the mouse held down. However, talking to a high rated designer, he told me usually it is done with a second camera that sits perfectly aligned with the guns iron sights. I would imagine you would still have to have an animation that then transitions you into that iron sight camera though. Now my animation works fine but I feel I may run into a problem later down the road if I am approaching it the wrong way from the start. Can someone verify the right way to do this and explain why it is?

Updating the position of a prefab in Unity for A pathfinding I am trying to use Aron Granberg A pathfinding project in my game. I am very new to Unity, so I am having some trouble figuring out how to instantiate multiple enemies from a prefab that will seek out my player. I am unable to set the player object from the scene as the target, since prefabs cannot take in scene objects. However, if I use the player prefab as the target, the enemies will only go toward the starting position of the player. Is there any way to update the prefab position as the player instance moves? Or is there a better way of doing this? I want this to be a top down shooter style game (2D) with constant enemy spawning, so it doesn't make sense to set the target for each individual enemy instance. Any help would be greatly appreciated. Thank you!

Unity Manually sync location of players from server to client I am new to Unity networking. I've set up my scene with NetworkManager and the Player prefab having NetworkIdentity. I originally had my players set up to sync with a NetworkTransform. This worked, but the objects were very choppy whenever they were children of a moving object. In order to fix this issue, I've replaced NetworkTransform with a class extending NetworkBehavior, using UnityEngine.Networking, and containing the following code to sync localPosition void Update () CmdSyncPos (transform.localPosition, transform.localRotation) Command protected void CmdSyncPos (Vector3 localPos, Quaternion localRotation) transform.localPosition localPos transform.localRotation localRotation This works really well! The only problem is that this is one way, the server now has the updated position of all clients but the clients only have the updated versions of themselves. How can I do this in reverse Manually sync the location of non local players from server to client?

Unity Performance How many Materials per Object? I have learned that a Mesh with 4 Materials each 1024x1024 in Size is somewhat slower than a Mesh with 1 Material 2048x2048 in Size? In my usual workflow I tend to seperate different Materials into different Materials so an Object tends to have around 2 8 Materials. I have created more than a hundred Assets like this. Is the performance dramatically affected by this? Is it acceptable to upload such Objects to sites like turbosquid or sell them on Unity Asset Store or will the buyer behead me after noticing? Window Textures need to be transparent, Metal Wood Concrete need different smoothness settings. As far as I know Unity doesn't support Gloss maps.

ParticleSystem, performance behind the technique on batching with different materials I found that guide https thinhhb.wordpress.com 2016 03 27 unity3d optimization make atlas textures for particlesystem reduce drawcall why not which is quite clever. As far as I know, we can't batch ParticleSystems with different materials, for example A star (Particles Additive) A smoke (Particles Additive) give 2 draw calls. The guide points, that we can use a TextureSheet trick to achieve batching of different graphics on multiple ParticleSystems like that We create a spritesheet manually and cut it in Unity's SpriteEditor into a grid, and create a material Then, we create our ParticleSystems and attach generated sprites into Texture Sheet Animation Module And here the magic happens. They batch. My question is, what is the overhead behind this? Is the TextureSheetModule expensive? If I have 15 different sprites, their ParticleSystems create 15 batches, which is quite expensive on mobile. Is it wise, to move to TextureSheet and save these 14 batches?

Can't join to room through Unity's Matchmaking system on the Internet It works perfectly when I try to connect locally from my editor to my running build. But after I start the server on my Android, and try to connect to it from my editor, it time outs As you can see, it finds the match, and then tries to join, but it can't. If I try to do it from a build, the log says the following Log cannot connect after 10 attempt address ffff 127.0.0.1 7777 ClientDisconnected due to error Timeout Why does it tries localhost, when I obviously use the Matchmaking system? When I tried it on 2 Android devices, the same happened. Ps. I know that it's going to be depracated, I just want to use it during a short term gift. Thanks in advance!

RaycastHit2D.point is acting weird when used with circlecast2d When I make circleCast2d intersects with another circle collider, I get a RaycastHit2D.point that doesn't point at the tip of the collision as it states in the documentation. Instead it always points at the centre of the intersected junction or pointC as shown in the figure below. I checked this numerous times with different values to make sure the error was not from my end. Is this intended? If so is there another way where I can actually find the closest point from collider(B) to the centre of collider(A) which corresponds to point(D) in the figure? This is a picture of what looks like A circleCast B collided object C where RaycastHit2D.point is pointing at D where I'd like it to point.

Activate and Deactivate Collider with Click I'm having some trouble working with this, it's basically a sword that points toward your mouse position, and when you Left Click, a Trigger Collider is activated and then deactivated, but I can't get it to work. Here is my code void Attack() Activates the Sword Collider polygonCollider2D.enabled true Debug Line Debug.Log("Collider Active") StartCoroutine(Wait(0.1f)) polygonCollider2D.enabled false IEnumerator Wait(float seconds) yield return new WaitForSeconds(seconds) I did it this way hoping that the Wait method would give the game enough time to react to an active collider, and using some Debug.Log(). I know that the collider actually activates, but it does not react to other colliders. I keep wondering if this is the proper way of working with this. If it's not, do let me know.

Unity UI circular clickable area I'm building some somewhat involved UI stuff using the Shapes vector package. I need to be able to detect clicks on a circle, but also need to be able to click on things right next to that circle in all directions (it's a large circle). I can limit the detected clicks to within the circle by simply using a square and checking distance of click from center of circle. But this still obscures clickable things behind the square but outside of the circle (in the corners of the square). How can I detect those? Thanks!

Collision, triggering, and range detection in an RTS. What are the optimal solutions for unit spatial awareness? I've finally ran into the problem of multiple triggers and collisions within my 2D RTS. Up till now I've been using unities sphere colliders as a way of simulating spatial awareness. To trigger when objects have entered and exited a specific area around a unit or building so that they can be appropriately targeted. This became a performance problem when I started having hundreds of colldiers overlapping each other. Since the units are aware of projectiles as well as other units buildings, this becomes very expensive very fast. I've found that I can only manage to have a couple hundred projectiles and about 100 colliders within close proximity of each other before the game slows to a crawl just from PhysX. (hundreds of projectiles entering and exiting 100 collliders all the time) I did some research and found spatial partitioning mentioned all over the place. Is this a solution to the problem I am currently presented with? Are there other solutions for objects to have spatial awareness of potentially hundreds of other objects at a time without bringing my CPU to it's knees?

Open sourcing a Unity game with assets So, I have a goal to make and publish one (small, stupid, simple) game every Saturday. (I've made two, so far, thanks for asking.) I've started in Unity, because it's convenient. My plan for each game was to have a free version with ads, a paid version without, but also have it open sourced (and if they're willing to go to the trouble of removing the ads themselves, so be it). Now, concurrently, I keep wandering into e.g. Humble Bundle, or Unity Asset Store sales, and picking up things I probably don't need but maybe might use. It has just occurred to me, though, that if I'm open sourcing these games I kinda suspect the owners of these assets aren't going to be happy with me just posting all their files on the internet. Pretty sure I can't open source assets I've purchased. Now, I could probably just use free assets and make note of where they came from, and everyone would PROBABLY be ok with that. But that significantly restricts the things I can use. (And it would be kindof a waste you don't want to know how many ancient untouched game dev Humble Bundles I'm sitting on, haha.) Is there some kind of workaround? Like, if I posted the whole project, but included a license stating that only my code was open sourced, and the rest could not be used in anything else, for instance? Anybody know any nice solutions?

Unity associated game object is null when running I am just starting with Unity. I have two UI Text game objects, Atext and Btext. I have associated them by drag dropping with my PlayerController script public variables, say public Text atext and public Text btext. Before running, the Unity editor correctly shows that Atext and Btext are correctly associated with the public variables. When running with debug, I get a null reference exception with btext and even the Unity Editor shows the association as None (Text). After stopping, the association turns to Btext as it is supposed to be. The script is very simple and I don't set btext to null at any point. When I create a new UI Text object by duplicating Atext, it works correctly after associating it with some new variable. When I create a new UI Text object by Create UI Text, it doesnt work Might be a stupid question but what am I forgetting? Edit Here is the problem again with code Before running with debug, the editor shows PlayerController2 (Script) Script PlayerController2 Speed 7 Countboxref Countbox(Text) Winboxref Winbox (Text) Brokenboxref Text (Text) where Countbox, Winbox, and Text are Canvas UI Text objects which I have drag dropped into place. Winbox object has been created by duplicating it from Countbox, Text has been created by Create UI Text. enter using UnityEngine using UnityEngine.UI using System.Collections public class PlayerController2 MonoBehaviour public float speed public Text Countboxref public Text Winboxref public Text Brokenboxref private Rigidbody rb private int boxit void Start () Countboxref.text "count" Winboxref.text "winner" Brokenboxref.text "broken" When the program breaks on line Brokenboxref.text "broken , the editor shows Brokenboxref None (Text) and when the execution is stopped completely, it again returns to Brokenboxref Text (Text) Note 1 In this project, every Text object created with Create UI Text is broken. A new Text object works only when I select Countbox or Winbox and duplicate it. Thus it is not possible that the object would be explicitly destroyed in the code. I can create as many Text objects as I wish by copying (all don't work) and as many Text objects as I wish by duplicating (all will work). Note 2 when I create a new project from scratch, of course everything works as expected. I assume the project is somehow corrupted. Edit 2 No prefabs or such. Just the basic roll a ball tutorial. But this was my son's project so I am not sure what he has done when following the tutorial. Note 3 The problem went away when I deleted the Library folder and forced Unity to rebuild it. Don't know yet if I caused any other problems by doing that. I saw that somewhere as a suggestion for corrupted projects. I don't know if there is a proper way to refresh. Also, this project was originally started with Unity 4.6 and upgraded to 5.02

Picking targets for homing missles I'm developing 2.5D space shooter (3D objects, 2D gameplay). I'm searching for a way to pick targets for homing missiles. There are two types of missiles active radar guided and heatseekers. The first ones are relatively simple to implement I search for a target once and then store it in the missile's navigation code. If object is destroyed or escapes missile's triangle of view, I seek for another target. Searching for target is costly, because I have to iterate through all game objects and eliminate ones behind the rocket or out of its "radar range". However, that happens rarely only after launch and when missile loses the target from sight, so I guess it will be acceptable. Now imagine heatseeker missile. Situation is different here I have to make decision about flight direction on every frame gather information about nearby heat sources, create some kind of heatmap, find hottest direction and navigate rocket towards it. This may degrade performance especially if I have multiple missiles on scene and this is very likely scenario. I thought of using collider as first degree sieve to keep track of potential targets. This collider would have to be quite big but it would narrow down count of potential targets to 10 20 and I guess that should be acceptable for processing. However, I'm falling into problem of multiple colliders I use one for regular collisions and I wouldn't want the other one to interfere. Also, I'm not sure what is the performance penalty for having a couple of big colliders on scene. How can I solve the problem of picking target for missile every frame such that it won't have big impact on overall performance? Are the colliders correct path to follow? Or should I rely more on coding than on built in features?

Isometric coords to cartesian coords I'm new to the tilemap feature of Unity, and I'm having a hard time with all those coords. I created a new project, added an isometric tilemap and left all values to their default. In the Unity Editor (and in game at runtime as well), the coordinates of the cells are like this This is pretty disturbing to me and it will be to most players (not programmers) too I guess. I would like something like this However, I can't figure out how to do the transformation. I tried this Vector3 currentWorldPos Camera.main.ScreenToWorldPoint(Input.mousePosition) Vector3Int currentCellPos grid.WorldToCell(currentWorldPos) This gives the coordinates as in the Unity Editor except for z currentCellPos.z 0 Set z to 0 so the coordinates of the cell are exactly as in the Unity Editor Vector3 cartesianCellPos new Vector3((2 currentCellPos.y currentCellPos.x) 2, (2 currentCellPos.y currentCellPos.x) 2, 0) Try to transform the Unity coordinates into cartesian coordinates WRONG RESULT But this calculation gives weird results, not what I expect at all. Do you know how I could transform the Unity coordinates shown in the first screenshot into the coordinates shown in the second screenshot?

For creating a distant moon in a 3D game, is it better to use a model or texture? I'm working on my indie game and I want to create a moon (it's a 3D game) however I am unsure if I should create a model and put it far away, or if I should use a texture on a plane and have it constantly move so the face of the plane is facing the player. The problem I had last time I tried a model is the render view, as the model was really far away (as when I did it very small, you could sort of tell it was a tiny model rather then a far away moon) and with the texture I'm not sure if it comes across as tacky. I'd really like to hear the pros and cons of each, since I'm planning to use the 'render objects only when in view' method and basically want advice on which I should go with.

Changing alpha of Sprite I'm using OnGUI to draw a rect when I "box select" or "drag select". The texture that gets drawn is a PNG file made in Paint.Net with the opacity alpha channel set quite low. In Unity however, when I go to box select, the texture is completely opaque. How do I get Unity to honor the alpha set in Paint.Net? I also wouldn't mind using Unity itself to adjust the opacity, but I haven't found such an option in the import texture part of the inspector.

How Can I Fix Where The Tile Spawns? I am making a 3D game in Unity and C . I want to spawn another tile when the player is at the end of the current tile. But when I spawn the next tile it doesn't spawn at the right place(just after the current tile). How can I fix this? Thanks Old Code using System.Collections using System.Collections.Generic using UnityEngine public class Terrain MonoBehaviour public List lt GameObject gt objs new List lt GameObject gt () public GameObject terrain public GameObject player private float z 4130.875f private float safeZone 260.0f private float tileLength 260.0f private int animTilesCount 2 void Start() for (int i 0 i lt animTilesCount i ) spawnTile() void Update() if (player.transform.position.z safeZone gt (z objs.Count tileLength)) spawnTile() DeleteTile() public void spawnTile() GameObject go go Instantiate(terrain) as GameObject go.transform.SetParent(transform) go.transform.position Vector3.forward z Debug.Log(z) Debug.Log(Vector3.forward z) Debug.Log(go.transform.position) go.transform.rotation terrain.transform.rotation objs.Add(go) z tileLength public void DeleteTile() Destroy(objs 0 ) objs.RemoveAt(0) That's the position of the current tile. The correct position for the next tiles would be (6.103516e 05, 3.051758e 05, z). They have to spawn after the current tile.

How to fix this unexpected movement? I am facing a problem below is the detail. There are two scripts(actually more than two but these have the problem) Cannon.cs and Launch.cs and three buttons(up, down, and launch) to move cannon and launch the bullet. Cannon have bullets and each bullet has Launch.cs attached also a RigidBody2D. When specific event occurs the Cannon.cs calls the Launch.cs's Launch(direction) method. Parameter "direction" Cannon.transform.right. Bullets are being instantiated dynamically and are stored in the list Cannon.cs take one bullet and fires it(firing includes calling the Launch(direction)) . Launch(direction) will always be called once no matter what also to double sure myself I destroy the launch script on launch. The problem is once the bullet is fired or launched in the direction specified by the direction of cannon(since direction cannon.right) and I click on the up or down button the launched bullet changes its direction which should never happen because Launch() method is called only once in the lifetime of the bullet and also I detach the Launch.cs script on launch. I am using rigidbody2D.velocity direction thrust what I think is that rigidbody2D.velocity once called will possess the direction just like a method called by reference. I am totally lost I hope I made my question clear please do help me if you can.

What causes this graphics quality difference between WebGL Build and Unity 5 Editor? The Editor version and WebGL version of my Minesweeper clone have some graphics quality differences. I chose 'Fast' option when building this deployment. Is this the difference between 'Fast' and 'Fastest' options of Optimization Level in Build Settings, meaning that if I choose the 'Fastest' option, the WebGL deployment will be the same as Editor version, unlike below? If not, why this happens?

Unity 5.3.5 Blurry UI text after switching canvasses until text is refreshed by turning visibility off on or changing resolution I have multiple scenes in my project where the canvas are switched between, each canvas having UI text included on it. The project was originally created in version 5.0 and I have just updated to version 5.3.5 and I am now encountering the following issue The canvas that is active when the scene first loads displays all UI text just fine, but as soon as I switch to another canvas with the exact same text on, the text on the new canvas is blurred. As soon as I turn the text object off on (via a button click) it appears to refresh it and it all displays fine again. It is also rectified by changing the display resolution in the editor play window. It appears as though unless it has a 'refresh' through clicking something else, or is on screen when the scene first loads, it appears blurry. The font is 'Open Sans Bold' and I am switching canvasses via a raycast script. I have read issues of text blurriness in 5.3, but most instances appear to be down to the size of the text being in odd numbers which mine isn't. Screenshots attached. The settings shown are the same for all canvasses and text. Any help would be appreciated. Thanks in advance

Blurry text in Unity UI at default scale I'm working on a VR (GoogleVR Cardboard) game, and need to include UI elements within it. Ever since I first learned how to use Unity's UI elements, I've been limping around what seems to be a major problem at the default (1,1,1) scale, literally everything involving fonts that I add to a world space Canvas ends up looking like scaled, blurry bitmaps. I can kludge around the problem by manually changing the scale of everything UI related to (0.1, 0.1, 0.1) and multiplying the dimensions of everything by 10... but I can't believe this is how Unity's UI editing is intended to work by design. Somewhere along the line, I must have overlooked something major. The question is... what? Is there an option somewhere to either make Unity render fonts at a higher resolution, or to at least change the default scale for new items from (1,1,1) to (0.1, 0.1, 0.1) amp multiply all the default dimensions for new UI items by 10?

In Unity, how do get access to animation clips in selected model from EditorWindow? I need to add some animation events or copy them from other models. So I decided to make a EditorWindow. Unfortunately there's not much information about this, and I'm stuck in here. void OnGUI() GUILayout.Label("Source Object contains Animation Clips", EditorStyles.boldLabel) sourceObject (GameObject) EditorGUILayout.ObjectField(sourceObject, typeof(Object), false) if(GUILayout.Button("Copy")) if(sourceObject null) throw new System.NullReferenceException("Source Object is missing.") Do Copy here What I need to do is Extract all animation clips from the selected model(fbx) it's the source object Select "AnimationClip" to want to copy. Note that AnimationClip in here is not inside of model, it's seperated AnimationClip that duplicated from original model because basically animation clip from imported model is read only, so I have to duplicate to update it. How do I get animation clips from selected fbx model with ObjectField? Any advice will very appreciate it.

Thing is that they must be in classes, so for example I wrapped this code (which is from PadControl.js) pragma strict public var ball GameObject public var moveSpeed float 10 public var rotationSpeed float 10 function Update () var padMove float Input.GetAxis("Horizontal") var padRotate float Input.GetAxis("Vertical") this.transform.position.x padMove moveSpeed Time.deltaTime this.transform.rotation.y padRotate rotationSpeed Time.deltaTime function OnCollisionEnter(col Collision) if(col.gameObject.name "Ball") Debug.Log("SAY SOMETHING") like so pragma strict public class PadControl public var ball GameObject public var moveSpeed float 10 public var rotationSpeed float 10 function Update () var padMove float Input.GetAxis("Horizontal") var padRotate float Input.GetAxis("Vertical") this.transform.position.x padMove moveSpeed Time.deltaTime this.transform.rotation.y padRotate rotationSpeed Time.deltaTime function OnCollisionEnter(col Collision) if(col.gameObject.name "Ball") Debug.Log("SAY SOMETHING") As stated in this tutorial coming from Unity's website (https unity3d.com learn tutorials modules intermediate scripting statics) But when I do it, this is the error Assets PadControl.js(12,22) BCE0019 'transform' is not a member of 'PadControl'. Assets PadControl.js(13,22) BCE0019 'transform' is not a member of 'PadControl'. And I really don't know what's actually going on and what should I do. Any suggestions?

Can I add non trees to terrain.terrainData.treeInstances on Unity 3D? I need to create a brush in which there will be stones, poles, bushes and other elements of the environment. I bought a Prefab Brush. Whether it is possible to add the objects that I draw on the Prefab Brush scene to terrainData.treeInstances, as regular trees add? Is it possible to use a not prefab tree as an object for the TreeInstance class?

Strange artifacts in Unity Lightmaps I experienced this weird lightmapping bug in my game that causes some models to have glowing artifacts on their surface. These artifacts "move" around, when I edit the UVs of the model in Blender, so I assume that it has something to do with them. I took a few screenshots to hopefully clarify the issue. Engine used Unity 2019.1.4f1 3D Software Blender 2.79b If you need any other screenshots or something, let me know. Thank you in advance!

Flatten transform hierarchy at build time Nested hierarchies cause a performance overhead when they include moving objects. Every time a GameObject moves, altering its transform, we need to let every game system that might care about this know. Rendering, physics, and every parent and child of the GameObject needs to be informed of this movement in order to match. As the scope of a game increases, and the number of game objects skyrockets, just the overhead of sending out all these messages can become a performance problem. However, nested hierarchies are useful in organising a scene and keeping logical groups of gameobjects separate. What options exist to save performance whilst keeping the hierarchy? Is there any pre existing solution to flatten a hierarchy when building only?

How to handle back press in Unity? By back press on Android, I want to close all the open windows first then exit the game, I see everywhere it's suggested to check input key in Update void Update() if (Input.GetKey(KeyCode.Escape)) if (AreAllWindowsClosed()) Input.backButtonLeavesApp true But my issue with this is that it's calling the code in every frame and also may handle a single press multiple times! Isn't there a single BackPressed event in Unity for this simple task?

How can we view 3d objects from top down view in TD game I am making a tower defense game. I am working in x and y axis only. I have made a grid, snapped towers and made a pathfinding algo to run enemy. Initially I have worked with cubes and spheres in place of towers and enemies. Now I am going to place real towers (3D). Note that I haven't used z axis up till now. The user will analyze the game from top down view. I want the user to see towers placement with a little bit of 3d view but I have made my all code in 2d thing. Is there any solution to my problem that somewhat tower placement would view a 3D touch or you can say 2.5D ?? (like fieldrunners) or should I have to involve z axis and ignoring y axis ?

NavMeshAgent.CalculatePath produces a PathInvalid result Anyone know what can cause NavMeshAgent.CalculatePath to return false and give a path with PathInvalid status? I have two characters each character has a NavMeshAgent. Character x is a standard Humanoid, character Y is a vehicle with a custom agent type. Characters start out in scene A, which has two NavMeshes, one for each type, and both are able to navigate just fine. Characters get moved to DontDestroyOnLoad so that scene A can be unloaded and scene B can be loaded. Scene B has two NavMeshes, one for each type. Characters are placed on the ground, on a valid NavMesh location. NavMeshAgent is asked to path to another valid location on the NavMesh. Character Y (the weird one) paths just fine, but for character X, the call to CalculatePath fails and the NavMeshPath object's status is PathInvalid. I honestly have no idea what's going on here. If anything, I'd expect pathing to work for X and fail for Y, due to it being a nonstandard (and larger) agent. Not sure if the scene change is relevant or not including it just in case it is, and to show that the basic setup is working for 3 4 scenarios here. Anyone know how to go about debugging this?

Setting Camera's Viewing parameters manually I am working on Context aware camera in Unity. in this project i have to set parameters of the camera each frame manually depending on what camera sees on the screen. New View (v) direction is given and Up (u) and Right (r) vectors should be such that they minimize torsion with previous frame's u and r. I have deployed the following code to accomplish the given task Vector3 viewNew m Normal Vector3upNew Vector3.Cross(viewNew,m CameraPrevTransform.right).normalized Vector3 rightNew Vector3.Cross(viewNew, upNew).normalized ... transform.forward viewNew transform.up upNew transform.right rightNew The problem is it seems like Unity tries to automatically adjust parameters when one of the directions (up, forward, right ) are set. Is there a workaround ? is it possible to get more control of the camera?

How can i put a skybox on a new layer with a new camera and then move the skybox? I want to create a moving start effect. For example the space station is moving around the star or moving to the star. But instead moving the space station i think it will be better to make effect of the skybox moving. I have in the Hierarchy a RigiBbodyFPSController and a child MainCamera. Now i added a new Camera to the Hierarchy. Now how do i make the rest ? Moving the new camera and the skybox to new layer and move the skybox ? Or it's more logic to say to move the new camera that the skybox is with in it in the new layer. Not sure if my idea is logic or if there are a better ways to do it. The general idea is to make movement effect like the space station is moving around the star or to the star. Star i mean the skybox. The skybox is on the right. I can't see the skybox in the scene view i see it only when running the game in the game view. This is a screenshot when the game is running then i can see the skybox in scene view and game view

Control Camera with gyroscope and place a gameobject always in front of it Actually I have came here after searching from past 5 6 hours. Actually I am making a small game in which I have a camera and a gameobject. The Game Object is place in the center of the scene at 0,0,0 . My scene doesn't include anything but a skybox. I wanted to move my camera with gyro input, I got that working. My problem is that I want my object which is at 0,0,0 is to face camera always. The camera is controlled by gyro so the object should always remain infront of the camera. I have taken a script from wiki.unity3d and it seems to be somewhat working. Actually I want an offset for the transform.lookAt or if it's not possible I'll require some solution for it. public class CameraFacing MonoBehaviour public Camera m Camera void Update() transform.LookAt((transform.position) m Camera.transform.rotation Vector3.forward, m Camera.transform.rotation Vector3.up) Actually I have tried 3rd person and FPS shooter camera and Camera Follow script as well besides knowing it doesn't fit my need. As In most cases we want the camera to follow object. But in this case my input is through gyro of mobile device and I want the center object to always remain in front of camera. Here is the code for gyroscope. I have made the object which I want to always stay infront of camera as suggested by comment but the camera rotate with gyro but not the object that is child of it, which is pretty strange. private float initialYAngle 0f private float appliedGyroYAngle 0f private float calibrationYAngle 0f void Start() Input.gyro.enabled true Application.targetFrameRate 60 initialYAngle transform.eulerAngles.y void Update() ApplyGyroRotation() ApplyCalibration() public void CalibrateYAngle() calibrationYAngle appliedGyroYAngle initialYAngle Offsets the y angle in case it wasn't 0 at edit time. void ApplyGyroRotation() transform.rotation Input.gyro.attitude transform.Rotate(0f, 0f, 180f, Space.Self) Swap "handedness" of quaternion from gyro. transform.Rotate(90f, 180f, 0f, Space.World) Rotate to make sense as a camera pointing out the back of your device. appliedGyroYAngle transform.eulerAngles.y Save the angle around y axis for use in calibration. void ApplyCalibration() transform.Rotate(0f, calibrationYAngle, 0f, Space.World) Rotates y angle back however much it deviated when calibrationYAngle was saved.

submeshes and dynamic batching doesnt work as expected I'm duplicating one object with submeshes frequently, and assigning a random material from five materials to each submesh. There is batching happening, but it's not quite as efficient as I would have expected (details here). Note objects are all less 900 vertices no light maps and ... All are dynamic batching ready So if dynamic batching works there must be only 5 draw calls right but there isn't there is really much more than 5

When and where and how to turn on back the Player first person when loading a scene on button click ? In the Build Settings I have two scenes at index 0 and index 1 Then in the Hierarchy I have the two scenes The active scene is the MainMenu In the StartGameButton I added to it a script component. In the script using System.Collections using System.Collections.Generic using UnityEngine using UnityEngine.SceneManagement public class LoadSceneOnClick MonoBehaviour public void LoadByIndex(int sceneIndex) SceneManager.LoadScene(sceneIndex) And this is the StartGameButton Inspector I dragged the script on the OnClick I selected the function LoadSceneOnClick And set the index to 1 When the game start and I click on the button it stay on the Main Menu scene and not loading anything. The problem I guess is that I'm getting error in the game No cameras rendering The problem is that when I'm running the game and it start from the main menu scene in the space station scene I'm enable false the Player and the Player is a first person character with a camera You can see in the Inspector that the Player is unchecked the Player is not enabled. If I will enable the Player and even if the main menu scene is the active one it will show me the player and the player camera and not the main menu. So I had to turn off the Player. The question now is where by script do I enable back the Player when it's loading the scene ? Inside the LoadSceneOnClick script ?

With gravity enabled, how do you move a RigidBody forwards at a specific speed? I have a perfectly smooth cube on top of a perfectly smooth plane. I am applying a forward force of 1 unit per second, using rigidBody.AddForce(new Vector3(0, 0, 1), ForceMode.VelocityChange). I apply this force every FixedFrame(), taking into account Time.fixedDeltaTime, of course. When the "Use Gravity" checkbox on the RigidBody is not checked, the object behaves as expected after exactly 3 seconds, it has a speed of exactly 3 units per second. However, when I enable the "Use Gravity" checkbox, the object barely moves. Both the object and the surface are using Physic Materials with zero friction, and the moving object's RigidBody has zero drag and zero angular drag. Why does this happen? And more importantly, how would I apply a force to this object so that it moves forward at, say, exactly 3 units per second, with gravity enabled? Thank you.

Loading .PNG file and using it for UnityEngine.UI.Image Have an Unity UI Image. I want to load a .PNG file that is in my persistent data path and use it as the sprite source for the UI Image. Code byte bytes File.ReadAllBytes(Application.persistentDataPath " sprite.png") Texture2D texture new Texture2D(width, height) texture.filterMode FilterMode.Trilinear texture.LoadImage(bytes) Sprite sprite Sprite.Create(texture, new Rect(0,0,width, height), new Vector2(0.5f,0.0f), 1.0f) myObject.GetComponent lt UnityEngine.UI.Image gt ().sprite sprite This almost works. Only a portion of the image is displayed. The initial guess would be that I didn't load the image properly. However, if you use a SpriteRenderer instead of UnityEngine.UI.Image like myObject.GetComponent lt SpriteRenderer gt ().sprite sprite The image is displayed in full. So this seems to be a problem with UnityEngine.UI.Image specifically... ... However, if you drag an image from the editor into the Sprite Source property of UnityEngine.UI.Image, then such image is displayed in full then suggesting that there is something wrong with the way I load my image bytes. What should I do? Edit If you set the image type to Tiled, you can see that it tiles with the full image... So apparently the UI Image component DOES have all the image data but for some reason it won't render all of it.

Unity prefab object limitations TLDR What are limitations on how many objects a single prefab can handle safely? keeping in mind that I could potentially have almost a 100 of these I am busy creating a system to essentially load the game world in chunks as the player moves. This means that every single object in the world will be streamed into the game through script when needed(still designed in the editor, impossible otherwise) The problem I am having is with methods to store and load objects. I have looked at everything I could think of or get information on. After researching all the methods I found, I started thinking that prefabs is the best solution since it can live anywhere in the project(unlike streaming assets folder, which is also not recommended for many assets, let alone every single asset). Creating Game Objects at runtime is not as easy once GO's get complex with components and settings, also I assume the performance hit from creating GO's this way is worse than using an existing prefab. So my question is if prefabs can handle massive amounts of objects(lets say 1000) safely? testing this is hard because i would have a prefab(or a few) for each tile that gets loaded.

How to move rigidbodies Have i understood this correct If i want to use a rigidbody for physics then i should not move an object through its transform.position. I should never move it by riigidbody.velocity since i then affect the physics. So what is left is moving it using addForce. I guess its like mimicking how in the real world everything that moves has something that drives it.

Match 3 should pieces store their location in the matrix? I'm making a match 3 game. I have a TileManager script which stores all the tiles in a matrix, it's a singleton and it handles tile swapping and basicly everything regarding the management of tiles. I have a variable called selectedTile. I have a method called SwapSelected which swaps the currently selected tile with the one you just clicked on. As pieces don't know their location in the matrix I can only loop through the whole thing to find them but it feels extremly stupid I just feel like there's gotta be a better way. If pieces stored their location and I kept that updated all the time that'd feel stupid too. What could I do to make this method work nicer and more optimalized? Is there a way or there is no problem with how I do it? public void SwapSelected(Tile tileToSwap) Vector3 tempPos selectedTile.transform.position selectedTile.transform.position tileToSwap.transform.position tileToSwap.transform.position tempPos Vector2Int tileToSwapPosition new Vector2Int( 1, 1) Vector2Int selectedTilePosition new Vector2Int( 1, 1) OPTIMALIZE!!!!!!!!!!!!!!!!!!!!!!!!!!!!! for (int x 0 x lt tileMap.GetLength(0) x ) for (int y 0 y lt tileMap.GetLength(1) y ) if ( tileMap x, y tileToSwap) tileToSwapPosition new Vector2Int(x, y) if ( tileMap x, y selectedTile) selectedTilePosition new Vector2Int(x, y) tileMap selectedTilePosition.x, selectedTilePosition.y tileToSwap tileMap tileToSwapPosition.x, tileToSwapPosition.y selectedTile UpdateTileName(tileToSwap) UpdateTileName(selectedTile)

StateMachineBehaviour.OnStateExit is called before StateMachineBehaviour.OnStateEntered is called When I start my game I get null references in my OnStateExit of objects that are initialized in the OnStateEntered.

Reused Avatar moves mesh I have a humanoid avatar and it's animation controller. I also have two different human meshes, they're quite similar. When I use the generic avatar and it's controller in the animator the meshes shot out into the sky and perform their animation correctly. The animations run normal they just move in weird directions and don't stay in their original locations. How to fix it so the mesh doesn't move far away and retain original position?

How to make an object that has no rigidbody2d component smoothly fall on the ground in Unty2d? I have two character in my game enemy and main character. Enemy can throw different objects into the main character. For this moment i am doing this action in such way void FixedUpdate() if (CanMove) transform.position Vector2.MoveTowards(transform.position, TargetPlayer.transform.position, 15 Time.deltaTime) public void StartMove(bool canMove) CanMove canMove TargetPlayer GameObject.FindGameObjectWithTag(Tag).transform rigidbody2D.gravityScale 0 This script is attached to the prefab of the object that will be thrown into main character by the enemy. This script is working, but in this case the object that was thrown will follow by main character all the time, because of this line of code transform.position Vector2.MoveTowards(transform.position, TargetPlayer.transform.position, 15 Time.deltaTime) To my mind this is not good, because i want to give my player the opportunity to escape from the object that was thrown at him. For example run away. When the object reaches the player position (and the player is on the new position) he will simply fall onto the ground. I did this, but this wasn't looking nice, because when the object was reaching his position, he was hanging in the air. Can anyone give me an advice how to make this process more good looking? Edit I need to make good looking movement of the object, that was thrown by the enemy into main character. Every frame i am moving the instantiated object to the current player position. So the player can't escape from that object, because he always knows current player position. I think that this is not good idea, and i want to give to player an opportunity to run away from that object. In this case i am saving the position of the player into variable, and then every frame i am moving the instantiated object to that position. So when the player run away, the object, that was thrown doesn't know anything about new position of my player. But this is looking not good, because when the object is reaches its destination position he hangs in the air(( Edit 2 I was thinking about destroying that object anyway, but to my mind this will not look good the object is moving and suddenly disappears from screen(. May there is some ways how to make him smoothly fall onto the ground? The problem is in that this instantiated object has no Rigidbody2d component attached to it, so it will never fall down by itself.

unity animation won't play unless input key is held The code is simple. If the player presses the right arrow key, one animation clip plays. If the left arrow key, another clip plays, etc. However, the clip doesnt play fully unless the input key is held continuously. The second you release it, the second the clip stops playing. I think it's something to do with update() and the input not being remembered over next frame. The code is simple using UnityEngine using System.Collections public class animatorcontroller Logic MonoBehaviour Animator anim enum MovementState Idle 0, run 1, walk 2, MovementState currentMovementState void Start () anim gameObject.GetComponent lt Animator gt () void Update () if(Input.GetButton("right")) currentMovementState MovementState.run else if(Input.GetButton("left")) currentMovementState MovementState.walk else currentMovementState MovementState.Idle set movement state to idle anim.SetInteger("MovementState", (int)currentMovementState)

Is white the best base color to start with when planning to shade sprites within Unity? I'm looking into prototyping a game in Unity which will consist of solid square sprites tiles. I figure I can represent different types of objects with different colors for each of the tiles in the game. I figure that I can import a single square sprite and shade it appropriately in Unity as opposed to imported squares of many different colors. My experience with adjusting the hue and saturation within Photoshop shows that white is not an easy color to change as things that are white often stay white. My testing in Unity shows that I can change the "color" of a sprite to anything other than white and the sprite is seemingly shaded appropriately, despite what I would have thought given my Photoshop experience. Since white objects do seem to take on the appropriate color shading when changed within Unity my gut tells me that this is the best base color to begin with, meaning that I can import a single white square sprite and simply adjust the color to represent different objects and object states. Is a white sprite actually the best color sprite to begin with and why does something like this work in Unity as opposed to adjusting the hue and saturation within Photoshop?

Networking and physics Context I have been implementing my own networking for a third person multiplayer game, but controls and physics will be ala old school FPSs. I'm using Unity's transport layer, which allows me to send and recieve raw data between server and client. I used this model as reference, in order to implement better client response http www.gabrielgambetta.com client server game architecture.html Implementing prediction, and interpolation was no problem, but I'm having a problem implementing reconciliation, even though I successfully implemented for normal ground movement. I do the following each tick Client The client sends the server the delta updates on the player position, and the server validates this movement and updates the player accordingly on the server. Server I send a snapshot to all clients with all players' positions. Each client interpolates the rest of the players, and reconciliates it's own position. Reconciliation Ground movement seems easy, because each frame the player input determines how the player moves Each FixedUpdate, the player moves a certain distance. This makes reconciliation really easy, since knowing which was the last input the server has received, your client just needs to consider the rest of the inputs yet to be processed. Reconciliating jumping But I don't know how to deal with jumping. Jumping is an input that has an impact on the player's position over several frames while it's airborne (and for a few frames, as the placer decelerates in case his air speed was high). This means I can't just rely on the input "jump" to recalculate my client's position, since depending on the moment I'm present, I could be ascending, or descending. Even more, if I jump and collide with the roof, killing all my vertical speed, the movement would be completelly different. This lead me to think I should be sending to the server each update on the player's position Instead of sending "hey, im jumping here", I could send "I'm moving up 1 unit"..."I'm moving up 0.9 units".... describing the players parabole. But I feel this method is not enterily secure, since the client could be sending "I'm moving up 1" ever single time, allowing the player to just fly away. So the server has to be the one handling the physics on the jump. Other scenerios This problem is also present in anything physics related When the player is pushed away by an external force set up by the server or the client itself. If the client recieves a message saying has been affected by an explosion, I could set the client's speed accordingly, but If I have any kind of air control (which I want to have), I need to tell the server the change on air speed If the server makes a correction on the physics made, I need to be able to predict and reconciliate the position AND speed. For example If I collide against a wall in the server, which for some reason, is not present in the client, I also need to kill the player speed or it will keep slamming into an invisible wall. Posible solutions There are several solutions I was thinking about, but I'm not really satisfied with any of them As said earlier, I could could let the client handle the air movement by sending the position update back to the server, but this feels insecure since th client could technically make himself fly around, and make himself immune to being pushed away. Besides sending the player positions, I could also send the players' speed, storing this information could make reconciliation easier and more reliable, but it will also increase the size of snapshots and network usage. Maybe I'm missing a clever alternative, but I don't really see any other option. Any ideas?

Vector3 Array serialization ReorderableList I've been working on a ReorderableList, but it's given me quite the headache. I've come to the point where I want to define a "drawElementCallback" callback, which looks like this list.drawElementCallback (rect, index, active, focused) gt EditorGUI.PropertyField(rect, list.serializedProperty.GetArrayElementAtIndex(index), GUIContent.none) What it's supposed to draw is one Vector3 object from an array of Vector3 objects. I get this property like this ("property" is a SerializedProperty that contains the property that I need) SerializedProperty locationsProperty property.FindPropertyRelative("locations") The array is declared as follows public Vector3 locations Inside a container class that is marked as "Serializable". The problem I kept getting with different code is that the ReorderableList shows all the Vectors correctly but it doesn't allow me to reorder any of the items, nor delete them (I can add new Vector3 objects and change them as expected). With this code, I wanted to fix that issue. However, now I keep getting the following error "InvalidOperationException The operation is not possible when moved past all properties (Next returned false)" I wanted to make a reorderable list because it seemed easy, but I can't figure out the problem and I honestly wish I hadn't started working on it. It's taken up most of the past 3 days. If anyone knows how to fix this, I would be very grateful. To clarify, this code shows the array properly list.drawElementCallback (rect, index, active, focused) gt SerializedProperty item locationsProperty.GetArrayElementAtIndex(index) EditorGUI.BeginChangeCheck() item.vector3Value EditorGUI.Vector3Field(rect, string.Empty, item.vector3Value) But doesn't allow me to remove or reorder items. I thought I should show the code to demonstrate that there are indeed array items.

2D Unity How to make a enemy jump from a navmesh platform to another? I'm currently working on a 2d platformer, however I came across an issue where the enemy moves within a certain range of the platform. In this case I use a navmesh to limit the enemy's movement however I want the enemies to be able to jump within platforms. I'm not sure how to achieve this effect, where the enemy moves in the platform a couple of times and the jumps into the next one until the player gets in range for it to attack the player. How can I acheive this effect? Should i keep on using navmeshes or try another way around?

How do you support different VR platforms? I created an Android app for Gear VR in Java (using the GearVR framework) that I now want to port to Unity, so it can also be used for Microsoft's semi new Mixed Reality headsets (for Windows not HoloLens, though). I've never worked with Unity (or C ) before, that's why I have a question How would you set up something like that? Can you simply create a single project and then put it on your (Android) phone compile it on your PC depending on where you want to test it, or do you need separate projects for different platforms?

How to use 3 cameras simultaneously in Unity I'm working on a project that requires 3 panels, each rendering a game object. There will be a search box and when the player enters a string, that key word will zoom to the tagged location on the each object in the 3 panels. How can I go about accomplishing this?

Do I need a server to connect two players in a mobile game? I would like to make a 2 players app game, where 2 players can compete with each other in real time. If I want the player to be able to compete with the public (anyone who registered with my game able to compete with one another), do I need a server? If I want the player to be only able to compete with his facebook friends, do I need a server? Do I need a server at all in the first place, for 2 players game?

How do I import multiple animations into the same file in Unity? I have hit a major stump in my development applying transitioning animations to the same model. I have learned how to do a single animation with keyframes, but have no clue on what to do with more than one. I tried importing different animations seperately and applying them to the same model, but it didn't work. How can I get past this stumbling block?

2d ParticleSystem batching problem I have multiple ParticleSystems with TextureSheetAnimation pointing to the same texture, using different offsets rows to choose different textures. They seem to batch with each other, but they're also being split by Unity into multiple batches in a strange manner. Here's a Frame Debugger view These 4 Draw Dynamic are on the same atlas, using Mobile ParticlesAdditive shader. The reason of breaking batching is Objects have different batching keys. This is usually caused by using different vertex streams on ParticleSystems or by mixing Lines and Trails, or by mixing lit and unlit geometry. All of the ParticleSystems have a simple setup, some Color Over Lifetime, some Velocity Over Lifetime etc. The strange thing is that Unity breaks batching like it makes one batch, puts half of the stars and half of the smokes into that, and then, makes another batch from these two. So they do batch, and the don't o.O I couldn't find and help on the web about this issue. I'd be glad for help.

Critical input from server arrives late... it must not! To preface, my understanding of networking is mostly from Source Multiplayer Networking and 1000 Archers on a 28.8. For various reasons I have decided to go with a client server model instead of peer to peer. My C Unity multiplayer game is ruled by an authoritarian server, which uses UDP. Each network instruction has a time index, and is inserted into PlayoutBuffer's data collection. The buffer executes stored commands at the correct local time index, based on a fixed update loop. The server is slightly ahead of time, and clients will pause if they have not received any regular update from the server, allowing them to catch up. Each client will simulate object movement and this movement is corrected by the server (ten times a second). I've got the basic system working, but when I'm testing it in two windows on the same machine sometimes input arrives late, and is dropped. Usually the late message is 1 time index too late. The fixed loop is 50 ticks per second. The server is 5 ahead of time, and commands are scheduled 5 ahead of time (assuming negligible lag, since ping hasn't been implemented yet and is on the same machine). This is a problem. Inputs from server are grouped into a few specific channels Ping, Serialise, Inputs, Criticals, Corrections. Ping has yet to be implemented. Serialise packs and unpacks mostly pregame multiplayer lobby stuff. Inputs are player commands select unit, issue move order, etc. Criticals are essential updates create unit, shoot unit's weapon, damage unit, etc. Corrections are mostly movement updates. All channels are unordered and with the exception of Corrections all channels are "Reliable" in Unity terms (see Unity documentation). Given that movement updates happen regularly, if a few are dropped or arrive late this is not a critical system failure. But if a critical is lost, this would effectively result in a desync. How can I prevent and handle critical data arriving late from the server? My first thought is to implement a custom ping. This is used to set the time index for the data relative to the time the last ping took to get back from the client, plus server time index. But I doubt that would be enough... and if it fails? Should the client pause or catch up based on the difference between local time index and the time index in the late critical? Does the PlayoutBuffer need to become an AdaptivePlayoutBuffer to resolve these issues to handle CPU and network lag? If so, how so? Any other ideas welcome! EDIT The reason inputs were arriving one time index too late sometimes was because the buffer's for loop which read inputs counted from 0 to list.count, and removed items as it iterated... when I changed it to reading from list.count to 0, it fixed the issue and no inputs arrived late. Whoops.

How to fix lag in 64 bit Android devices My game's FPS drops to 30 8 FPS on any 64 bit Android device but is at 59 60 FPS on an even lesser 32 bit Android device. I've tried unchecking Development Build on Build settings and I've tried disabling debug calls on my game by using void Update () if UNITY EDITOR if(!Debug.unityLogger.logEnabled) Debug.unityLogger.logEnabled true else if(Debug.unityLogger.logEnabled) Debug.unityLogger.logEnabled false endif But there wasn't any change. And I tried setting all Stack Trace Log type to None(Edit gt Project Settings gt Player). Also no change. PS I used that update call because there are other imported assets that call the Debug class and I wouldn't want to mess around with their classes. EDIT As you can see in the screenshots below, the device that runs the game at less than 30 FPS(every 64 bit device) has Gfx.WaitForPresentOnGfxThread take 71.6 of the frames and RenderPipelineManager.DoRenderLoop Internal() takes up 51.1 . While the device that ran the game at 60FPS(every 32 bit device) has RenderPipelineManager.DoRenderLoop Internal() take up the most frames with 35.7 of the frame. How should I fix the frame rate drop on the 64 bit device? EDIT The 32 bit Android device is an Infinix Hot 4, 2GB RAM, 1.3GHz quad core MediaTek MT6580 CPU, OpenGLES2, Android 7.0, 1280x720. This reaches a maximum of 62FPS(Average 59FPS).

Game objects all blue underneath I have an empty scene with a single object in it, a cube. The cube renders initially as pink, when it has no material attached. When I attach a material though. Any material. Odd things happen. I have created some extremely basic materials, which are just colours. Some metallic, some not. If I apply when of these the cube does not go the colour expected. The exception of this is the Green and Blue materials, although I suspect they're the wrong shade. Please see below Why could this be happening? My settings look pretty standard on the cube... If I create a brand new cube and set the materials up the exact same thing happens. I have downloaded some sample materials from the asset store, and they behave strangely too. A brown wood bark texture does the following And here is that texture, definitely no sign of blue. There are no lights set up, and the cube is the only item live on the scene, everything else is switched off. I have also added a camera and rendered the scene. Same thing. Is there some sort of ambient light setting or something I am missing quite obvious? Really not sure what to do here.

Animation is not starting even though collider is triggered? progress is steady but it is a bumpy road. I have removed the animation script from my character and reworked it into the controller script. I have also added new animations. Doing this required replacing the character FBX I was using earlier. Doing this has caused an unexpected problem Remember that super cool item box that I made, that the character can trigger when he jumps under it, causing it to play an animation where the lid pops off? Well, that's broken now. The box's idle animation still plays, but the GetItem animation does not. Before importing the new character, his animations and the box's animations were in the same animation controller. I separated them into their own controllers, and applied them each where they belong. I did not make any more changes ( you can see all its properties in the demos below). There are still no transitions or parameters for the ItemBox. Funny enough, I tested it and the ItemBox's trigger is being activated. What could be wrong? Video links (SHORT) Link to video of new character demo Link to Animators Panels Video How can I get the GetItem animation to play for my itemBox again? whoops, here is the relevant script ItemBox.cs using System.Collections using System.Collections.Generic using UnityEngine public class ItemBox MonoBehaviour Start is called before the first frame update bool disabled false Animator anim void Start() anim GetComponentInChildren lt Animator gt () if (!disabled) anim.Play("ItemBox Idle") Update is called once per frame void Update() void OnTriggerEnter (Collider other) if (!disabled amp amp other.gameObject.tag "Player") print("itembox triggered") anim.Play("ItemBox GetItem") disabled true This is the heirarchy for the ItemBox prefab. Notice that animation frames can only be seen from first child ("Parent") of that prefab, downward UPDATE! GetItem animation is playing in the animation graph while I play the game, hitting the box from below, but the animation doesn't play in the game! The plot thickens! See (shorter) video shorter video

Use Unity Handles for interaction in the scene view I want to give an object with a specific script arrows to do special functions in the scene view. I have gotten Unity to render the arrows but I have no idea how to actually handle mouse events. The docs appear to say that I should be able to identify what receives a mouse down event by calling HandleUtility.nearestControl however when clicking on different arrows in the scene view I get the same ControlId (which i'm guessing is the gameobject itself). How are you supposed to know deal with mouse events properly? Code CustomEditor(typeof(Script)) class SceneGui UnityEditor.Editor void OnSceneGUI() if (Event.current.type EventType.Repaint) Transform transform ((Script)target).transform Vector3 pos transform.position Vector3.left 2 Handles.color Color.yellow Handles.ArrowHandleCap(3000, pos, Quaternion.LookRotation(Vector3.left), 2, EventType.Repaint) Vector3 pos transform.position Vector3.right 2 Handles.color Color.red Handles.ArrowHandleCap(3001, pos, Quaternion.LookRotation(Vector3.right), 2, EventType.Repaint) Vector3 pos transform.position Vector3.forward 2 Handles.color Color.blue Handles.ArrowHandleCap(3002, pos, Quaternion.LookRotation(Vector3.forward), 2, EventType.Repaint) Vector3 pos transform.position Vector3.back 2 Handles.color Color.cyan Handles.ArrowHandleCap(3003, pos, Quaternion.LookRotation(Vector3.back), 2, EventType.Repaint) else if (Event.current.type EventType.mouseDown) Debug.Log(HandleUtility.nearestControl)

A.I. dependencies based on components I'm working on a turn based game in Unity. I need to perform field grid analysis(2D grid) when i'm iterating trough each unit "entity". The A.I. should be able to plan ahead and therefor needs to consider the components each unit have. Not every unit will have the same ability. These abilities are defined as components. I want to make it flexible in the sense that I can plug in new abilities and my A.I. will take it into consideration. While user control is somewhat implemented, A.I. hasn't even been written. So I'm open to any suggestion. Q What is a way for the A.I. system to collect all abilities of one unit and make decisions depending on each component? edit I know there is the "null" checking method to see if the gameobject contains a component. But this is highly inflexible because you are hard coding a stack of if else. Something I want to prevent.

maya root motion animation jumps back and forth in Unity I have a custom made model from Maya that is supposed to have root motion. But when I put the animation into the animator in Unity it keeps jumping back. I have configured the model in Unity as Root motion. So now I don't know whether it's a problem with the model in Maya or the setup in Unity. I have compared my Unity setup to a Jose Diaz Toon Dinosaur setup which seems to be the same so I am suspecting that there is a problem with the model export from Maya.

Prevent counterclockwise rotation So I have an object that has a handle attached to it, the player is supposed to rotate this handle. For that, I'm taking in the horizontal and vertical axis of a controllers analogue stick and transform these values into degrees, which I then use to rotate the object. The problem is that I can't seem to completely block out the possibility of rotating the handle counterclockwise, as the player is only supposed to rotate it clockwise. What happens is that every couple of frames while I try rotating counterclockwise it detects a clockwise rotation, executing my according code, even though I was rotating counterclockwise consistently. The principles I use to determine which direction the rotation is going is done by comparing the input angle of the last frame to the current input angle, like Variant 1 var inputAngle Mathf.Atan2(x, y) Mathf.Rad2Deg float angleDifference inputAngle previousAngle if (angleDifference gt 180f) angleDifference 360f if (angleDifference lt 180f) angleDifference 360f if (Mathf.Sign(angleDifference).Equals( 1)) Counterclockwise rotation else Clockwise rotation ... previousAngle inputAngle In another attempt, I tried to do this comparison by simply checking if my current angle is larger than my previous one while having the input transformed in a 0 to 360 range and also handling the overflow from going back to 0 from 360 , which did not work consistently either. So I tried to see what the values are giving in this faulty case, but what this told me was simply that the values are not as I expected them to be, as the current angle should be smaller than the previous one while rotating counterclockwise, in those cases and I can't figure out why or how to prevent it? So I guess in the end my question would be how can I consistently prevent a player from rotating counterclockwise by reading a controller's analogue stick input.

It lags when it collides. Help? ( I am trying (and believing) to make a game of pong. I have got a slightly decent working game. I haven't implemented the scoreboard or AI yet because I want the physics to work first. I am trying to reverse the direction of the ball when it hits either paddle just to make it work cleanly and am having the issue where it changes direction twice, it bounces off the paddle as expected and then goes in the opposite direction to when it hit the paddle .

Even though that's the right way to reverse the direction. I think. Thanks Peeps!

Correcting imported animation to avoid hand going through the face of character I've imported an animation from Mixamo called standing draw bow. When I use it with my character in Unity the hand goes through the face of my character. Is there a way to move hand a little outside the face of the character using Blender or Unity? Or am I required to make up the animation myself? I tried modifying parameters Mixamo offers but doesn't resolve the problem. I actually tryed to solve the problem with IK by adding a Multi Parent constraint ( cause i didn't manage to have multi postion constraint to work ) and tried to move lowerarm r Bone a little bit off the face of the character but it only did force the bow to stay in the position and rotation of the quot Target quot while being buggy in certain keyframes. my aim is to force that bone to not rotate more than certain degree to not go through the face while executing the animation. I believe the problem is coming from the fact that animation is made for normal head character not big head ones.

How to join two cubes? If I want to make a character (in Blender) made of cubes, to export it to unity later, should I leave these cubes and all the other body parts as separate objects, or join them all into one mesh? And, If I should join them is it a good idea to leave the cubes elements inside of each other? Or I should remove them, add some loops and connect the vertexes? In the last case it will be difficult to keep the cubes surfaces flat, because of the vertex shifting during joining.

Making an 'anim in circular motion' get attracted by gravity of the center I am working on a project, where the main player anim is in circular motion with respect to a center point. This video shows what I have done to the anim till now. In that video, there are multiple apples are in circular motion. However, in my case, there is only one anim which is in circular motion. I have tried the following code for the circular motion. public Transform center public float degreesPerSecond 65.0f private Vector3 v void Start() v transform.position center.position void Update () v Quaternion.AngleAxis (degreesPerSecond Time.deltaTime, Vector3.forward) v transform.position center.position v The above code works perfect for the circular motion. At the center (0, 0), I placed a circle sprite with 'point effector 2d' component. (see below image). The reason why I 'added point effector 2d ' is to apply gravity effect to the player. But that didn't work. The player anim which is in circular motion around the circle sprite should get affected by gravity of that circle sprite and it should be pulled towards the center. Changing the 'Point effector 2d' parameters is good enough to create gravity? or do I require any change in code?

Unity How to create C classes with different properties like Objects in javascript and put them in an array? I just started my gamedev journey on unity this week and while I have a background with coding, I'm still somewhat of a beginner. Last year I made a text UI based game on the web browser with javascript and have been trying to make the same game on Unity. One of the main features of my game is that you press a button to "go hunting" and I had an array filled with enemies that were objects with different properties such as health, mana, attack, etc... Then I'd randomly pick one of those objects from the array to be chosen as my enemy that I'd fight. I've been trying to figure out the best way to do this with C and I might just be overthinking this. As a bonus, I'd also like to be able to see the individual enemy objects in the array in my inspector if possible so I could tweak the stats within unity. I've looked at scriptableObjects and different things but I am having a hard time putting it all together in an array from within unity. System.Serializable public class playerClass public string playerName public int lvl public int maxHealth public int health public int maxEnergy public int energy public int exp public class playerScript MonoBehaviour public playerClass player This is how I created an object for the player, I want to do something similar for the enemies but put them in an array so I could randomly pick from them. If there is a better way to do this I'd also welcome some advice ) thank you

Advice regarding Unity hosted content I'm currently trying to build a mobile application that, for the purposes of trying to keep small in size, I would like to have store much of its content Online and be downloaded to the users mobile when the application requires it. Ideally I'd like to do so not just as a means to reduce the applications original size, but also to allow new assets to be introduced over time (such as new objects and textures) without the user having to reinstall the application or download a new update. I am at the moment researching into the use of Unitys Addressible Assets for these purposes, and am currently trying to test and implement this idea on a small scale using assets stored using Google Cloud storage. If possible however I would like to to ask whether anyone here has any experience with storing and accessing assets on an external server, and if so, might they have any advice as to whether or not this could be a feasible solution for these purposes? Any help would be really appreciated, as this is an area that is completely new to me. Thanks in advance.

How can I create an "afterimage" effect like this one? How can I make an effect like this? With a particle system?

Does PBR mean only one, right technique to view 3D scenes? For example if I call Unity 5's render pipeline "PBR" (Physically Based Rendering) and also call Unreal Engine 4's render pipeline "PBR," does it mean that the same model with the same PB textures will be viewed identically in very similar or equal scene setups on both engines? I just wondering if someone says "PBR," does it mean only one, single, right way to do "PBR," or do implementations vary from one to the other?
