Building meshes conforming to terrain deformation I have an uneven terrain on which the player is supposed to build buildings. For most structures I can just fudge the foundations, have them extend through the terrain. For roads, pipes, tracks and such I do have however the problem how to make them line up. What techniques can I best use to make the meshes of adjacent pieces line up, making it conform to the terrain?

Unity finding force vector to separate colliders in OnTriggerStay events In Unity, I have Trigger Colliders, and catch the OnTriggerStay(Collider other) events. Once two Colliders are touching, how do I get the Force vector to make them want to separate again? In the example below, I have a Sphere and a Box Collider touching. The OnTriggerStay is being called for the Sphere. I cannot use the center positions of the transforms to get a direction, as that would not give me a very good force vector And I do not think I can use the Collider.ClosestPointOnBounds to figure out the Box touch position, because the point I look from (center of Sphere), could be inside the Box Collider itself, which I understand will just return me back the center of the Sphere again. I would not be able to resolve any force vector from that.

Unity Raycast not detecting layers I am having problems with layers detection using raycasts. Context I created a grid to use in a pathfinding algorithm on a 2D plane. I want to implement now different weights according to the layer each node of the grid is in e.g. a node in a normal terrain will have a "terrainPenalty" of 1 and more difficult terrains 2 or more. In order to detect the terrain type on the 2D plane, I am shooting a raycast on the node position for each node previously considered "walkable". The problem comes up now, because I observed that the paths created are neglecting such values, this is the slice of code which is giving me problems if (walkable) Ray ray new Ray(worldPoint Vector3.back 10, Vector3.forward) PROBLEM HERE (NOT DETECTING PENALTIES) RaycastHit hit walkableMask walkableMask if (Physics.Raycast(ray, out hit, 100, walkableMask)) walkableRegionsDictionary.TryGetValue(hit.collider.gameObject.layer, out terrainPenalty ) At first I thought that the problem was how the layers were called, because I created a LayerMask combining 2 layers using the bitwise OR operator, but then I tried to play around with all the layers (hence why there is walkableMask walkableMask now). The result was always a false output for Physics.Raycast(ray, out hit, 100, walkableMask). I thought that maybe I was getting the wrong coordinates for the ray, but I created some gizmos to actually check that the ray was piercing perpendicularly my plane and it did, as well as trying to change layers to see if anything worked, but the output is always false. What am I getting wrong? Here is the rest of the function, if needed I can upload the whole script as well void CreateGrid() grid new Node1 gridSizeX, gridSizeY Vector3 worldBottomLeft transform.position Vector3.right gridWorldSize.x 2 Vector3.up gridWorldSize.y 2 for (int x 0 x lt gridSizeX x ) for (int y 0 y lt gridSizeY y ) Vector3 worldPoint worldBottomLeft Vector3.right (x nodeDiameter nodeRadius) Vector3.up (y nodeDiameter nodeRadius) bool walkable !(Physics2D.OverlapCircle(new Vector2(worldPoint.x, worldPoint.y), nodeRadius, unwalkableMask)) bool walkable !(Physics.CheckSphere(worldPoint, nodeRadius)) int terrainPenalty 0 if (walkable) Ray ray new Ray(worldPoint Vector3.back 10, Vector3.forward) PROBLEM HERE (NOT DETECTING PENALTIES) RaycastHit hit walkableMask walkableMask if (Physics.Raycast(ray, out hit, 100, walkableMask)) walkableRegionsDictionary.TryGetValue(hit.collider.gameObject.layer, out terrainPenalty ) grid x, y new Node1(walkable, worldPoint, x, y, terrainPenalty) EDIT Here is how I create the layerMask foreach (TerrainType region in walkableRegions) walkableMask.value region.terrainMask.value is the bitwise OR operation, I could have simplified by writing " " walkableRegionsDictionary.Add((int)Mathf.Log(region.terrainMask.value, 2), region.terrainPenalty) Where TerrainType is the following class System.Serializable public class TerrainType public LayerMask terrainMask public int terrainPenalty I basically create an array of TerrainType objects that will store their layerMask and penalty and then upon positive output from the raycast I access the dictionary to retrieve the terrain penalty. For the terrain and obstacles I am using a 2D BoxCollider and 2D PolygonCollider respectively, they do not interact with any other layer. Thanks for any possible hints, I don't know what else to try .

Issues using NetworkServer.Spawn with Unity and Mirror Networking I am using Mirror to handle the networking aspect When I spawn an object on the network, I Instantiate it on the server and then use NetworkServer.Spawn to notify all clients to spawn the object. However, when this object is eventually spawned on the client side, it seems to be spawned at the wrong position for a few seconds and then corrected itself and move to the correct position as is reflected by the server. Is there something I am not doing? Is this normal? Also I noticed if I changed the Network Sync Mode to 0, then it will only spawn in the wrong spot for a split second. using System.Collections using System.Collections.Generic using UnityEngine using Mirror public class EnemySpawner NetworkBehaviour public uint theId public int maxNumEnemies public int spawnDelay public GameObject enemyToSpawn float curSpawnTime BoxCollider2D boxColl Start is called before the first frame update public override void OnStartServer() curSpawnTime spawnDelay boxColl GetComponent lt BoxCollider2D gt () void Start() if (!isServer) return theId netId Update is called once per frame void Update() if (!isServer) return if (transform.childCount lt maxNumEnemies amp amp curSpawnTime lt 0.0f) Vector2 spawnPoint new Vector2(Random.Range(boxColl.bounds.min.x, boxColl.bounds.max.x),Random.Range(boxColl.bounds.min.y, boxColl.bounds.max.y)) curSpawnTime spawnDelay SpawnEnemies(spawnPoint,netId) else curSpawnTime Time.deltaTime Server void SpawnEnemies(Vector2 spawnPoint, uint theId) GameObject gobj Instantiate(enemyToSpawn, new Vector2(60.7f,1.3f), Quaternion.identity) gobj.GetComponent lt EnemyController gt ().parentNetId netId NetworkServer.Spawn(gobj) The way I've organized things, in the hierarchy I have Enemies Area1 Spider(Clone) Spider(Clone) Area1 has the EnemySpawner script.

Hide "No custom tool available" window I have this annoying window in the bottom right of the scene view. From the manual, it seems like I opened it by clicking on the wrench amp scribe button next to the movement buttons. How do I make it do away now? Restarting doesn't make a difference, neither does creating a brand new project. The documentation say this appears it I've clicked on the tools icon and there aren't any custom tools (which I'm sure I have done). Surely is should vanish after a while though.

Unity3d or WebGL Where should I go? I am interested in making a simple 3D game this summer, and I'd prefer if it were playable in a browser. My choices I am considering are Unity and WebGL. Currently I have no experience in either. But I have taken an introduction course to OpenGL. As well I will later be taking a course that will use Unity. I have some C experience, but no web background. The factors I'm considering are ease to learn and the penetration each has. I know Unity games can be uploaded to Kongregate, which seems like a pretty big deal if I made a game that would be somewhat successful. But of course that may not be the case at all. Which way should I lean? Personally I think learning WebGL would be the easiest transition, but I am not sure

How to make the character move along the axis using touch? I have the following code it works, but I don't know how it works. This is the code I found void Update() if UNITY ANDROID if(Input.touchCount gt 0 amp amp Input.GetTouch(0).phase TouchPhase.Moved ) Vector2 touchDeltaPosition Input.GetTouch(0).deltaPosition float offset touchDeltaPosition.x 40f 18 Mathf.Deg2Rad transform.position new Vector3(0f, 0f, offset) transform.position new Vector3(0f, 0f, Mathf.Clamp(transform.position.z, 7.1f, 7.1f)) endif I need to move the player along the axis by touch, for example, like in the game Cube Surfer! What I want to get (I used android emulator) The code I wrote works well at 720x1280, but if you set the resolution to 1440x2960, the controls become too sharp. I know why this is happening because touch.delta is getting too big. My code if (Input.touchCount gt 0) var t Input.GetTouch(0) var delta t.deltaPosition if (delta ! Vector2.zero) var offset transform.position offset.x delta.x Sensitivity Time.deltaTime offset.x Mathf.Clamp(offset.x, 4f, 4f) transform.position offset How to fix it? ScreenToWorldPoint this does not fit because the player moves along a spline. Thank for help

Subsurface Scattering Transmittance I have a question related to SSS and especially transmittance. I've looked at several papers about that topic, most of them from Jorge Jimenez, which are very interesting and, I admit, a bit hard for me. Here is one of the papers http www.iryoku.com translucency I have some difficulties to understand the way it works and the way it calculates the distance the light traveled through the object. I think that I understand the very big lines but I am also a bit confused as I am trying to integrate this into the Unity engine and I have some difficulties to match Unity engine available values such as the shadows maps, the shadows coords, etc... to make them fit the way they are used in the paper. So here it is, I am a bit lost in the "in between" and I hope that somebody might be able to help me. Thanks a lot. EDIT added the shader code from referenced paper float distance(float3 posW, float3 normalW, int i) Shrink the position to avoid artifacts on the silhouette posW posW 0.005 normalW Transform to light space float4 posL mul(float4(posW, 1.0), lights i .viewproj) Fetch depth from the shadow map (Depth from shadow maps is expected to be linear) float d1 shwmaps i .Sample(sampler, posL.xy posL.w) float d2 posL.z Calculate the difference return abs(d1 d2) This function can be precomputed for efficiency float3 T(float s) return float3(0.233, 0.455, 0.649) exp( s s 0.0064) float3(0.1, 0.336, 0.344) exp( s s 0.0484) float3(0.118, 0.198, 0.0) exp( s s 0.187) float3(0.113, 0.007, 0.007) exp( s s 0.567) float3(0.358, 0.004, 0.0) exp( s s 1.99) float3(0.078, 0.0, 0.0) exp( s s 7.41) The following is done for each light 'i'.

How to get light level (brightness) of a particular location? I'm making a 2D top down survival game similar to Rimworld, I'm trying to emulate a day night system. Many features depend on whether any tile is light (or dark) enough, based on time of day or other light sources such as torches, so I'm wondering if there's an easy way to detect how much light there is on a certain tile without making a whole system that tracks light on a per tile level (or maybe the latter option is better)? I am using Unity 2020.3.6f1 and the URP, which means I'm going to be using the 'new' 2D lights. EXAMPLE When it's nighttime, I'm going to disable the global light (sun) so those tiles will be pitch black. When it's daytime, the global light will have an intensity of 1 so that tile will have 100 brightness (look normal). When it's nighttime, but there's a torch, the tile where the torch is sitting on will have 100 brightness, and that will slowly fade to 0 over a span of 5 tiles. Making a system that updates every single tile in the game with information about the light level seems pretty expensive. Is there a way we can observe a block quot graphically quot , or in other words, literally look at the pixel on the screen, and determine it's alpha value to check for light level? Any suggestion is super welcome. EDIT Every tile does not need to know its brightness every frame, but they do need to know it less often. Some examples are A plant checking every couple of frames to see if it can grow A character checking every couple of frames to see if he's in the dark (and if he is, he needs to start panicking) More importantly, I need my characters to make decisions based on light amount. For an example, if there is a job that needs to be done at a certain location, a character should first check the light level of that location before going to do it.

Change Camera Contrast in VR Game Hello there Firends , I'm developing a Virtual Reality game in Unity. As in every VR game , i have 2 cameras for stereo rendering. I want to show the same object in each camera having different color contrast ratio gt The effect is similar to the one shown in this image the grid in the center here is the same in each side but each camera is seeing it differently.i.e. its grey in the left and black in right (you will notice the black grid if you look closely) here is another example (source wired.co.uk) How do i get this effect ? Any suggestions ?

Adding more effects to a Unity3d mixer I recently started exploring the wonderfull world of audio in unity. I noticed that you can add a bunch of effect modules to a mixer. Now I'm wondering if you can add your own custom effects( for example export a plugin from a audio program or something) and add them to the list. I cant seem to find anything related to the question.

Restrict the rotation of the camera using button I've been trying to limit the Y axis of the camera rotation but I'm out of depth until now. I'd looked up many tutorials and I found the clamping method, but I seem can't get it to work on my code, and all the tutorials I found is using them in Update(), while I'm using a button to rotate the camera. Here's the code public void RotateLeft() cameraY Mathf.Clamp(cameraY, minAngle, maxAngle) if(cameraY gt minAngle) Camera.main.transform.Rotate(0, cameraY,0) public void RotateRight() cameraY Mathf.Clamp(cameraY, minAngle, maxAngle) if(cameraY lt maxAngle) Camera.main.transform.Rotate(0,cameraY,0) Does clamping works outside an Update()? What am I missing? Thank you in advance.

What happens to deleted or added assets in your app when updating to a new version in the Google Play Store and iOS App Store? So let's say I used Unity and built an app and uploaded it to the android and iOS app store, it is 100 MB and lots of people downloaded it. So now I want to update it to the newer version, however along the way I decided a lot of features were unnecessary so I remove about 50 MB worth of assets and the new build is 50 MB so I uploaded it to the respective app stores. Will the people who already had my 100 MB app and now update to the new 50 MB version continue to have 100 MB of storage space taken up, even though the new one is half the size or will their app size be reduced to 5 MB according to the new build? Essentially, how does app store updating work? Is the whole old app deleted and new one downloaded? Are matching files and assets retained and only differences in files and assets deleted or updated? Or are new assets and files just piled on top? Additionally, for larger games, where the whole game is too big to be allowed on the app store, and where the player has to download more stuff once they have downloaded the game, how does it work? Is the additional, no longer needed content left on user's device kept there? Is it automatically removed?

GPU (render time) increase if screen size increase i create a simple 2d scene in unity 2017.3.1f1 I changed the size (height and width) in the Game View and proflie to see how it affects the rendering.. (below photo) I saw that the rendering time increases by increasing size, and now if this happens when playing the game on a different resolution android phone, each The higher the resolution of the phone, the more likely it is to get gpu bound !??? And i do not understand Cpu graph in the two situations in above photo(lower GPU gt higher CPU !!!) I tested my game on the quot huawei mate 10 lite quot (android device) with a resolution of 1080 x 2160 and it looks like there is a lot of rendering time.(a simple scene with only 5 sprite renderer) (unity dosen't show GPU profiling when game run on android device and we can't check these...) I did all the optimizations I heard, like DynamicBatching, Sprite Atlas , Quality Setting , sprite Texture Comprestion Override for Android.. What can be done to ensure that rendering time does not exceed a specified limit on different phones ??

Unity Sprite disappears completely when just a part of it is outside the camera's FOV I'm making a game in Unity, and when the player walks past a sprite, the sprite disappears, and when the player walks back toward it, it reappears.

Unity gameobject design approach for item drops In a game like Minecraft, the player could have any of several hundred types of items in their inventory. Players can drop those items into the world, but obviously how they're rendered in the world differs from how they're rendered in the inventory. I'm trying to understand how to design for this scenario using Unity's GameObject concept. Individually, it seems like the expectation is that I would have one GameObject (with at least a SpriteRenderer) for every unique item that can appear in world. I would have one GameObject (with at least an Image component) for every unique item that can appear in inventories. With so many, I also need to come up with some sort of directory so that I can associate bulk prefab objects for use in game. Is this accurate? I feel like that's a lot of overhead. Would I be able to create one GameObject with both a SpriteRenderer and an Image and maybe toggle between then based on whether its in world or an inventory? I had also considered using one generic GameObject and replacing the sprite image based on the item needed, but that feels like it's misusing what GameObjects are meant for. It also likely subverts the benefit of pooling them, etc. Is there another approach I'm missing?

Unity Is type casting every frame too expensive? I have a state machine that controls my enemy AI. Each AI has a target which may be a Player, an obstacle, a shell, or even a Vector2 position. I'm trying to abstract my "target" member, and my first thought was to use GameObject, then downcast to whichever type I need for different enemies. Examples below class StateController MonoBehavior GameObject target FireAction action Update() action.Fire(this) class FireAction ScriptableObject public abstract void Fire(StateController c) Examples of different fire scripts class FireAtPlayer FireAction public override void Fire(StateController c) Player p c.target as Player use properties of Player object class FireAtPoint FireAction public override void Fire(StateController c) GameObject t c.target as Player use properties of GameObject object As you can see, my Fire methods would cast the target object at every call to Update. Will this negatively affect my game's performance? Note that I know for a fact what type of object the target is, so I'm not guessing when I'm casting. Thank you in advance of your help!

Handmade Terrain vs. Terrain Engine in Unity? I'm planning a game right now, to be made in Unity, and I'm trying to decide how I'll approach the basic level construction. Essentially, my game takes place on an island in an infinite ocean, very similar to Wuhu Island My question concerns all the stuff heightmaps can't handle. To use Wuhu Island as an example, note the lighthouse cliff, and the nearby similarly jutting out cliff. The volcano itself is also empty, and there are some tunnels through it on the other side. I was thinking I would just model the entire island myself in Cinema 4D, but as I read more about the terrain system, it seems Unity has special optimized rendering systems in place for terrain objects. Would I be shooting myself in the foot performance wise if I just built my island entirely by hand? This will be for mobile, so the little stuff might well count. Am I even approaching this question correctly if not, how would you best go about creating (something very close to) Wuhu Island as a level in Unity? Is there any reason for me to not do it as one mesh? I have effectively zero experience with 3D game dev only rendered 3D video stills for other applications, so this is a learning process.

How can I use different fonts for different objects in Unity? In Unity 3.5, I have a font that is strangely linked to four game objects. I want to put separate fonts on each object. In the Inspector, when I click on the circle icon next to the "Text" attribute, I can select a font. But, then it changes the font on the other three objects as well. I was hoping Unity would have something like a material ID from 3DS Max. If I could put a new material ID on the other objects, hopefully I could assign a new font to the text mesh. Regardless, is there a way to assign a different font to each of my objects?

Tile Palette problem in Unity I am working on isometric tilemap in Unity 2019.4.8f1. In the Tile Palette panel, the selection is always 1 block away. Please see this screenshot In the screenshot, apparently I selected an empty tile, but in fact I am select the green tile with flowers. How come? Every selection is one tile away. The same issue happens in the Tilemap selection mode too. I have to select the adjacent tile in order to select the tile I want. How do I fix it? It's quite annoying. UPDATE I have added the settings of Grid, Tilemap as well as the import settings of the tile sprite sheet below. UPDATE 2 Changed the Pivot in Sprite Editor to Bottom Center Recreated the Tile Palette, and it looks like hovering 0.5 unit up.

Getting user id from one scene then to the next scene I'm new to multiplayer and photon so pardon me if this question is somewhat frequent. I have successfully set up my project to start from a main menu waiting room actual gameplay scene. However I couldn't search my way through getting a sort of user id from waiting room(ie order of user joined to waiting room) then use it in the gameplay scene to manipulate sort by score by hp etc. Perhaps I got the while concept of having to identify unique players via such variable? I'm not quite sure. I just got my foot in the multiplayer development realm, so please go easy on me. Edit Sorry for my initial question being quite vague. Basically, I'm trying to replicate this with Photon. I've got various things set up but was stuck at where designating individual players to individual player info panels as if captured(Get WHAT to connect to those UI elements I've got set up). It'd be simple enough even for me if this was a singleplayer, but since it's not I'm also refactoring a lot on the way as well. Thanks to both of the answers given so far I'm looking into Photon UtilityScripts(To a novice to anything simply directing where to look helps a ton, so thanks again), but since I'm not quite there yet I'll update my progress.

Unity Animation Controller and walking diagonally keeps switching between the two diagonals? Using Unity 2019.4.1f1 Personal. I have the above Animation Controller. When only walking in one direction at a time and when you stop you stay facing that direction, this works as planned. All of the transitions do not have an exit time and have a fixed duration of 0. I don't know what info to give as this is the first time I've used animation. Let me know and I'll add relevant details. Here's my update function that updates the variables in the animator void Update() float h Input.GetAxisRaw( quot Horizontal quot ) float v Input.GetAxisRaw( quot Vertical quot ) animator.SetFloat( quot Horizontal quot , h) animator.SetFloat( quot Vertical quot , v) if (Mathf.Abs(v) lt Mathf.Abs(h)) flips the renderer to reuse other handed image spriteRenderer.flipX h gt 0 no actual movement until I figure this out What I'm experiencing that I want to fix is when running diagonally It seems that when walking diagonally then the animator variables for Horizontal and Vertical are both either 1 or 1 and this causes the alternating of the sprites. What I'd like to happen is that the state machine would deterministically pick either N S sprites or E W sprites when moving diagonally. Turning on quot Can Transition To Self quot seems to properly pick a direction and stick to it but it fails to animate when only moving in a single direction. It looks like it's constantly transitioning to itself which starts over the cycle so I've left that unchecked on all transitions. I'm not sure what the best way to fix this is. Most attempts I've tried so far complicate the state machine to the point it's unmaintainable. I also couldn't find anything about introducing priorities in a way that fixed the jitter. What's the idiomatic Unity way to achieve clean diagonal movement in 2D?

How to calculate a movement Vector3 to kill unnecessary momentum and start moving in the right direction? Imagine a rocket is accelerating in a straight line toward PointA, picking up momentum every frame, then suddenly decides it wants to go toward PointB instead. It can't just turn straight toward PointB and start accelerating, because the new acceleration plus the pre existing momentum will carry it wildly off course, and not straight toward PointB. It could turn exactly 180 around to aim directly away from PointA and thrust until it comes to a stop, then turn toward PointB and start accelerating from scratch. But that's very inefficient, especially if the two points are in generally similar directions. It would be more efficient to turn and start accelerating in some specific direction that will bleed off the unnecessary momentum but keep any useful momentum, course correcting so that it is now moving toward PointB. I'm trying to figure out how to calculate that quot specific direction quot that the rocket needs to start accelerating toward, in order to efficiently reach PointB. I have the rocket's position, the Vector3 of its inertia, and the Vector3 locations of PointA and PointB, but I'm not experienced enough in Vector Math to totally understand what's needed. Especially since we're talking about acceleration (not just speed), so the angle will no doubt need to be recalculated each frame as the changing momentum leads to a changing angle toward PointB, etc. Can anyone help me out?

How to use Facebook Web Hosting for my Unity Game for both WebGL and GameRoom As can be seen from the Facebook's official Docs It says that To have both a Gameroom and a Facebook Web Game, you should leave your Facebook Web Games URL (https) unchanged. For example, https friendsmashsample.herokuapp.com and also Otherwise, if you only have a Gameroom title, you should enter https localhost as shown here I wanted to know if there is a way to get both of them working instead of hosting WebGL game on my server and putting it's URL? I have even tried to enable the Simple Web Hosting but the toggle just reverts Back to off upon saving.

Is it possible to apply a texture to a 2D sprite in unity 2 d? I want to take an (animated) 2 d sprite and apply a texture to it. Basically, I want every non transparent pixel to be covered by the texture (color is disregarded). I understand I can probably accomplish this using masks but I am worried that may not be the most performant solution. I know you can put textures onto 3 d models, so I was wondering if there was a similar process for 2d sprites. Below I have a graphic demonstrating what I want. What I have tried so far I see there is an option to add a material to a sprite, so I tried creating various materials. 1. Default material When I tried applying this material to my sprite, the sprite disappeared entirely. I suspect because this default material type only works on 3D objects 2. Sprite Material I figured sprites probably expect sprite materials, so I tried creating one. However, there does not appear to be anywhere to upload an image to use as a texture. This appears to only be useful for adding tints to sprites.

When is the CheckResources() function called? This question is asked in the context of image effect shader implementations in Unity. Looking through the scripts for image effects in the standard assets package, I notice that initialization is generally done in the CheckResource() function. The following is a snippet of code from the BloomAndFlares image effect. public override bool CheckResources() CheckSupport(false) screenBlend CheckShaderAndCreateMaterial(screenBlendShader, screenBlend) lensFlareMaterial CheckShaderAndCreateMaterial(lensFlareShader, lensFlareMaterial) vignetteMaterial CheckShaderAndCreateMaterial(vignetteShader, vignetteMaterial) separableBlurMaterial CheckShaderAndCreateMaterial(separableBlurShader, separableBlurMaterial) addBrightStuffBlendOneOneMaterial CheckShaderAndCreateMaterial(addBrightStuffOneOneShader, addBrightStuffBlendOneOneMaterial) hollywoodFlaresMaterial CheckShaderAndCreateMaterial(hollywoodFlaresShader, hollywoodFlaresMaterial) brightPassFilterMaterial CheckShaderAndCreateMaterial(brightPassFilterShader, brightPassFilterMaterial) if (!isSupported) ReportAutoDisable() return isSupported I am probably wrong in assuming that this is essentially the Start() or Awake() functions for PoseEffectsBase, but I decided to try implementing something simillar. public override bool CheckResources() saturationPassMat CheckShaderAndCreateMaterial(saturationPassFilter, saturationPassMat) if (!isSupported) ReportAutoDisable() return isSupported Unlike the standard asset scripts, CheckResources() does not seem to be called consistently for me. Unity console throws UnassignedReferenceExceptions every frame, for the object saturationPassMat. When is the CheckResources() function called? Should it be used for initialization just like Start()?

How to change Texture2D type to Sprite during runtime (Unity) How can we convert the Texture2D type to "Sprite" using the script (not in Editor)? It seems that the Texture2D retrieved from file is by default Normal Map. I need to convert the TextureType to "Sprite". Texture2D texture LoadPNG("D download.jpg") testPlaneRenderer.material.SetTexture(" source",texture) LoadPNG method code public static Texture2D LoadPNG(string filePath) Texture2D tex null byte fileData if (File.Exists(filePath)) fileData File.ReadAllBytes(filePath) tex new Texture2D(2, 2) tex.LoadImage(fileData) ..this will auto resize the texture dimensions. Debug.Log("File Exists!") else Debug.LogError("File not exists!") return tex It seems that this texture is set as "Default" or "Normal" Type when imported from file and then assigned to Material dynamically. As the particular shader I'm using, works best if the Texture Type is set to Sprite (I tested it by manually placing the texture file in Project and then assigning the texture to Material). I need to change Type of Texture to Sprite before assigning it to the material. I've seen options like "AssetImporter" but it only works in Editor. The effect of the shader (which takes two texture types a) Inverted amp Blurred Texture b) GrayScale Texture And then returns a Sketch Effect to the object. I convert the original image to inverted amp blurred, grayscale texture using some image processing code (C , Unity working around with GetPixels and SetPixels)... Output with Defualt Texture Type Output with Sprite Texture Type

Unity ScriptableObject Conversation Dialogue and Reading I'm unsure as to how I would reference a scriptable object's variables within a struct from another class. I know I'd have to make a public Conversation, but I'm stuck understanding how I could access it's struct, and how I could access individual variables such as the Position, or line string array. Is this method even viable or should I look at creating a different way of accomplishing a dialogue conversation scriptable object? Thanks for any insights and help My current code System.Serializable CreateAssetMenu(fileName quot New Conversation quot , menuName quot Create Conversation quot , order 1) public class Conversation ScriptableObject System.Serializable public struct LineData public string line public string option public enum Position BottomLeft, BottomCentre, BottomRight, MiddleLeft, MiddleCentre, MiddleRight, TopLeft, TopCentre, TopRight public Position position public enum TextSpeed Normal, Slow, Fast, UltraFast public TextSpeed textSpeed public LineData Line

In Unity3D, try to load a png into a Texture2D in an Editor script and then run PackTextures, but they need Readable flag to be set I am trying to automatically create a texture atlas from a set of generated png files in an Editor script. The problem is that I can't seem to be able to load a png into a Texture3D without it being inaccessible by the PackTextures method. I have tried a few different ways to load the PNGs, such as Resources.LoadAssetAtPath(...), AssetDatabase.LoadAssetAtPath(...) and a few more. Since all of this is done in OnPostprocessAllAssets, I don't want to have to do any manual editing of the textures. I just want to be able to drop a PNG into a certain folder and get an updated atlas. Answers such as this seem to suggest manual editing. The actual error message is "Texture atlas needs textures to have Readable flag set!". So the question is, is it possible to do this kind of post processing in Unity3D? Is there any way to import a PNG into a Texture2D with the Readable flag set, without having to manually change it?

How should I handle animation state systems in derived classes? I'm trying to get some kind of state system for my game objects. I have a base Actor class that is derived by classes like Policeman, Informant or Brawler. Each of those classes describes different functionality, but I want as much of the functionality to be shared. On of those is animation system. Each class has their own states (for example Policeman has Walking, Shouting and Shooting, while Informant has Idle and Whispering). What is the best way of handling such states? Do I have the Actor class have something like enum ActorState state1, state2, state3, ... And just map each behaviour of appropriate actor (Policeman, Informant, etc) to ActorState, so that the rendering system of ActorState can take over? Or maybe is there some better solution that people use. Game is 2D, sprite based, and I'm using Unity3D system, with Actor being a component to GameObjects.

Unity LWRP Projection Shader I recently added the Lightweight Render Pipeline to my project as I'd like to start experimenting with Shadergraph to see if I can get a better basic understanding of shaders. Everything has gone pretty smoothly except the Shader used by my Projectors, the Projection Shader Standard asset no longer works (does not project the texture) and I have very little experience with Shaders. The main concern for me is that I cannot find anyone else who seems to be having this problem. I have tried reading through the older shader and recreating it in ShaderGraph but I'm out of my depth. So could anyone provide me with a simple projection shader or materials on where I could learn to write one, or just learn more about them projection specifically. thanks edit To clarify I was using the Projectors to project a simple square texture on to each tile that I could tint, to show selectable current target tiles. Old shader that no longer works under Lightweight Render Pipeline From DevGuy Unity Forums Upgrade NOTE replaced ' Projector' with 'unity Projector' Upgrade NOTE replaced ' ProjectorClip' with 'unity ProjectorClip' Upgrade NOTE replaced 'mul(UNITY MATRIX MVP, )' with 'UnityObjectToClipPos( )' Shader "Projector AdditiveTint" Properties Color ("Tint Color", Color) (1,1,1,1) Attenuation ("Falloff", Range(0.0, 1.0)) 1.0 ShadowTex ("Cookie", 2D) "gray" Subshader Tags "Queue" "Transparent" Pass ZWrite Off ColorMask RGB Blend SrcAlpha One Additive blending Offset 1, 1 CGPROGRAM pragma vertex vert pragma fragment frag include "UnityCG.cginc" struct v2f float4 uvShadow TEXCOORD0 float4 pos SV POSITION float4x4 unity Projector float4x4 unity ProjectorClip v2f vert (float4 vertex POSITION) v2f o o.pos UnityObjectToClipPos (vertex) o.uvShadow mul (unity Projector, vertex) return o sampler2D ShadowTex fixed4 Color float Attenuation fixed4 frag (v2f i) SV Target Apply alpha mask fixed4 texCookie tex2Dproj ( ShadowTex, UNITY PROJ COORD(i.uvShadow)) fixed4 outColor Color texCookie.a Attenuation float depth i.uvShadow.z 1 (near), 1 (far) return outColor clamp(1.0 abs(depth) Attenuation, 0.0, 1.0) ENDCG

How I randomise a list of audio clips in Unity and remove it from the list once the clip is finished? I have 4 audio clips. When I play a press a certain button in Unity, the data is sent to MAX MSP and the audio is played. I created a list a signals (As shown below in the code). What I want is that, the signal list is randomised. The user presses a button to listen to the audio (which works fine). Once the clip is finished the user presses Next Trial button. Once the Next Trial is pressed. The previous clip is removed from the list. Once all the clips are finished. A message is displayed in the Debug.Log( quot All trials finished quot ). I have the following problems One of the audio clips is repeated again. It appears that the audio clips are not removed from the list. How do I write the audioclip index to a csv file?

ScreenToWorldPoint and ViewportToWorldPoint I'm currently following tutorials on Youtube to learn howto use Unity. My code runs perfectly as per the tutorial, but i just have some questions regarding the code, with regards to screenToWorldPoint amp viewportToWorldPoint. The purpose of the code is for a 2D platformer, where the character's arms will rotate and face where the mouse cursor is. Code using System.Collections using System.Collections.Generic using UnityEngine public class ArmRotation MonoBehaviour public int rotationOffset 0 Update is called once per frame void Update () Vector3 difference Camera.main.ScreenToWorldPoint(Input.mousePosition) transform.position Gets the difference between difference.Normalize() Normalizing the vector float rotateZ Mathf.Atan2(difference.y, difference.x) Mathf.Rad2Deg transform.rotation Quaternion.Euler(0f, 0f, rotateZ rotationOffset) I've done some googling and am aware of the difference between screenToWorldPoint and viewportToWorldPoint as per the answer here https answers.unity.com questions 168156 screen vs viewport what is the difference.html Where Screen from 0,0 to Screen.width, Screen.height Viewport from 0,0 to 1,1 Questions Why do we have to calculate the difference between the position of the mouse cursor and the position of the character's arm instead of just setting the following . Vector3 difference Camera.main.ScreenToWorldPoint(Input.mousePosition) I've tried setting it to the position of the mouse cursor instead of using the difference between the arm amp the cursor and while the code still works and the arm is still able to rotate, it is a little "off" from the direction of the cursor. E.g A little higher than where the cursor is. Why does using the difference solve this issue? Why do we call difference.Normalize() ? To my understanding, Normalize returns a vector between 0 amp 1.However, Mathf.Atan2 returns the angle in radians whose Tan is calculated by y x. As such, calling Normalize and returning a vector to a value between 0 amp 1 makes no difference because the value calculated will be the same between a un normalised and normalised vector since the proportions are the same? When i use ViewportToWorldPoint instead of ScreenToWorldPoint, i do not use Normalize because to my understanding, the Vector returned by ViewportToWorldPoint should already be within 0 amp 1, hance we do not have to normalise it. However, when i test the code out in play mode,the arm barely rotates. Why is this so? I would appreciate any help or pointers in the right directions. Thanks! EDIT I had a look at the manual and realise that Normalize() returns a vector with the same direction, but magnitude 1, but i'm still just as confused

On button click wait I have a button I got from google material design asset pack which has a ripple animation when pressed. I'm using the button's click option in the inspector that calls a method that switches scenes. But when I tap the button it switches the scene immediately and feels unnatural since the animation hasn't finished the button ripples animation. I tried using co routines. Made the button call a method in which I call a IEnumerator method (since the button can't directly call a co routine) and then switch the scene. But that doesn't work since it starts the co routine and switches the scene, the co routine never pauses the code and never finishes (probably because I loaded a new scene and the object that carries the script isn't transferred). Code example The method that gets called when I tap a button public void OnButtonTap() StartCoroutine(Wait(0.2f)) SceneManager.LoadScene("OnePlayerGameIntro") The wait coroutine public IEnumerator Wait(float seconds) yield return new WaitForSeconds(seconds)

Unity Seamless Terrain I am programmatically generating terrain using unity's terrain object and assigning height maps to it via the terrainData, the problem is that there are seams even when using the GroupingId(which is used for auto connect). I even tried creating a terrain object in the editor with neighbours, and modified their terrain data via script, seams still there. I have also tried SetConnectivityDirty after applying terrainData. Most people who have reported this seemed(lol) to have issues with their normals at the edges, I cant see that being the issue here, but if it is, how do i approach solving it given I am using unity terrains. If there is no good answer I will have to resort to custom meshes and lose all the nice terrain tool functionality. Edit Here is how I'm setting heights. var terrain GameObject.Find("test").GetComponent lt Terrain gt () var terrainData terrain.terrainData var noiseMap Tool Generators.GenerateNoiseMap(chunkSize, seed, scale, octaves, persistance, lacunarity, 0f, 0f) terrainData.SetHeights(0, 0, noiseMap) Then the actual noise generation is just a 2D array of heights, i have been using a simplified version with only 1 pass for testing. public static float , GenerateNoiseMap(int chunkSize, int seed, float scale, int octaves, float persistance, float lacunarity, float offsetX, float offsetY) float , noiseMap new float chunkSize, chunkSize for (int y 0 y lt chunkSize y ) for (int x 0 x lt chunkSize x ) float noiseHeight 0 float sampleX (x offsetX) scale float sampleY (y offsetY) scale noiseHeight Mathf.PerlinNoise(sampleX, sampleY) noiseMap y, x noiseHeight return noiseMap

pragma target 3.0 or 3.5? What is gained. What is lost for compatibility with older systems I've just designed an image based layering system shader. Multiple textures with Alphas overlay to create a fully dressed character, using 1 material. pragma target 3.0 is where I had started (suggested default in UnityProjects). After creating so many transparent overlay layers in my code, I got this Shader error in 'Custom Test' Too many texture interpolators would be used for ForwardBase pass (12 out of max 10) The fix seems to be to upgrade to pragma target 3.5 My game is going to be a Steam distributed game, PC only. What do I lose by using pragma target 3.5? Will only super dvanced PCs be compatible? Or should a fairly good average PC be able to run this? I don't know the intricacies of this subject.

How can I make a health bar a UI element part of a character prefab? Description I want my character prefabs to come with their own health bar, but I can't simply add one as part of the prefab, because it's a UI element and therefore goes into a Canvas. Potential Solution I could write a script that takes in a separate health bar prefab and instantiates it when the character prefab's instantiated, but it's one extra script. Is there a more conventional way to do this? I'd think this is a common problem.

Entity Interpolation (Lost Packets?) I'm working on a networked game for a while. I'm aware of client side prediction and lag compensation (shooting) but I'm not sure about entity interpolation client side. I'm sending update sync packets at 10fps from server and client interpolates from current position to newly received position. Interpolation takes 100ms (because of 10fps) to reach target position but what if new position arrives late or 2 3 packets drop? There will be no target position and sync'd (client side) entity will be idle until new position packet but entity continuously moving forward server side. Basically, I don't know what to do in this situation.

Unity Smoothing between two floats which are continuously changing I'm looking for some help with smoothing between an original float and a target float, where the original float is consistently changing (potentially interfering with interpolation techniques and or Mathf.SmoothDamp) I tried Mathf.SmoothDamp with the below (float rocketBoostPower is a global variable) float yVelocity 0.0F float tempForce rocketBoostPower Input.GetAxis("Mouse Y") shiftSpeed 5f rocketBoostPower Mathf.SmoothDamp(rocketBoostPower , tempForce, ref yVelocity, 0.5f) This doesn't change the force at all however, it just stays locked in place. I'm currently using the below to change my power, however I want to smoothly change the power instead of just incrementing sharply on each Update frame rocketBoostPower Input.GetAxis("Mouse Y") shiftSpeed 5f Please can someone help? I need the assumption that every update will receive a new rocketBoostPower value, whilst still smoothing its previous value.

How can I speed up Unity3D Substance texture generation? I'm working on an iOS Android project in Unity3D. We're seeing some incredibly long times for generating substances between testing runs. We can run the game, but once we shut down the playback, Unity begins to re import all off the substances built using Substance Designer. As we've got a lot of these in our game, it's starting to lead to 5 minute delays between testing runs just to test a small change. Any suggestions or parameters we should check that could possibly prevent Unity from needing to regenerate these substances every time? Shouldn't it be caching these things somewhere?

Why is there a difference in frame rate between my fps calculation and Unity's calculation So I wrote my own script for calculating framerate but it consistently comes out with a different value than Unitys idea of current framerate. This is my implementation void UpdateFPSStats() double frameTime new double() frameTime Time.deltaTime m times frameIndex frameTime frameIndex if (frameIndex m numberFrames) frameIndex 0 int numberSamples 0 double averageFrameTime 0.0f foreach(double t in m times) numberSamples averageFrameTime t if (numberSamples gt 0) averageFrameTime averageFrameTime numberSamples m frameRate 1 averageFrameTime where m frames is a list of the last 60 frames frame times and UpdateFPSStats is called in Unitys Update(dt) function. On average in my scene my fps calculation gives a steady 50fps, while Unity calculates a steady 80fps. Which is right and why?

How do I draw lines to a custom inspector? I have a custom editor to which I want to be able to draw a basic line graph. I have much of the functionality down, but I have only been able to test as much via the debug. I am yet to figure out how to draw the actual lines to the inspector. How do I draw lines to a custom inspector? I have found plenty of online resources, in regards to custom drawing to the editor. However, everything I find pertains specifically to drawing in the scene view nothing seems to work inside of an actual inspector. The two general methods I have found involve using Handles.DrawLine and the GL library. Neither appear to work however, I have only been able to test functionality with blind coordinates, so far. I can not find anything in regards to actually determining the local coordinates of the area on the inspector where I wish to draw. Perhaps I need to start with an initial "origin" position, Perhaps I need to start with a local area defined by a Rect. I simply don't know. It has also been a while since I had to use OpenGL, directly. It is entirely possible I am simply doing it wrong, to begin with. Here is my current graph method private void DrawVelocityGraph(float velocityValues, float minimumVelocity, float maximumVelocity) float velocityValue velocityValues 0 float increment 0 Vector3 lineStart Vector3.zero Vector3 lineEnd new Vector3(horizontalIncrement, velocityValue verticalIncrement) GL.Begin(GL.LINES) for(int i 1 i lt velocityValues.Length i ) if(velocityValue velocityValues i amp amp (velocityValue minimumVelocity velocityValue maximumVelocity)) Handles.color VelocityGrapherColours.outOfRangeColour else velocityValue velocityValues i Handles.color VelocityGrapherColours.lineColour lineStart lineEnd lineEnd.x increment lineEnd.y velocityValue verticalIncrement GL.Vertex(lineStart) GL.Vertex(lineEnd) GL.End()

Sea is higher than land when importing large real world terrain I am trying to import some real world terrain into Unity with the help of Global Mapper. The data I am using is download from CGIAR SRTM(http srtm.csi.cgiar.org ,http srtm.csi.cgiar.org srtmdata ). The land part works well but I am having trouble with the sea part. This is a larger view of that weird thing in the first image. This strange is actually the sea. This is happening because I am using the gradient shader. Lokks like The sea is represented with white, but when Unity reading the .raw file, the white means the highest part. Does anyone know how to deal with problems like this? Thanks very march.

In Unity, what does the camera script's "Behaviour missing" error mean? I started in Unity few days ago and made a cube with a tank control style. Now I'd like to create controls similar to 3D fighting games (Gunz, Blade Symphony, ) Control body direction with the mouse and walk with WASD. However, the Camera is giving me a error called "Behaviour missing" each time I try, with all the cameras scripts I saw. I think that is a error with tagging the character movement in the camera, but I don't know how to do that. What might be the problem?

How to make a class diagram and data model of a Unity3D game? I'm developing a 3D platformer video game on Unity3D and I've been asked to present its UML class diagram and data model. If I'm not mistaken Unity uses an entity component system, which necessarily doesn't use heritage. How would a class diagram from a Unity game look like, in that case? Also, I've been taught that usually data model refers to entity relationship models that represent a database. In the case my game doesn't use a database, how could I diagram the way the player's data is store on the game? I'm storing the player progress on a file in the user's computer.

Pixel art sprite distortion with 1 1 pixel ratio So I've been studying the Unity's PPU, pixel density, camera settings topic to make my game pixel perfect. I've set everything in a way that my screen pixel to sprite texel ratio equals 1. The art looks very good and crisp overall on the game view... But! There are still some minor distortions and I don't know where it comes from. Take a look at this example In this example my settings are Screen 870x510 PPU 100 Camera size 2.55 Pixel snap on Sprite material on The issue happens when I move the sprite manually by 0.001 values on the Y axis. Same happens on the X axis. Any ideas what's the problem?

Unity how to put a target under a character's feet that follows ground model contours? In my current projects, one of the power ups needs to place a target marker centered on the position of the player triggering it the actual design for this is TBC, but will be a circle with a radius of 10 units. The ground for the playing arena is a model, and not flat. Assuming that I use a texture to show this target area, how can I have this texture render following the contours of the ground? Alternatively, any other approach to solving this would be appreciated. Thank!

Switch Vector 3 x,y,z Components Based on Rotation I have a cube that moves by rotating on its edge. I want my code to also work for cuboids. The following code is what I'm using to rotate my cube turnPoint transform.position new Vector3(0.5f direction x, 0.5f, 0.5f direction z) Location of edge (resets every 90 degrees) transform.RotateAround(turnPoint, axis, rotateSpeed direction) Turn around the edge It works fine, however I want to get this to work when the cube is scaled to be a cuboid. I tried multiplying the new Vector3's x, y and z components by the objects respective x, y and z scale. This works, but only for the first rotation. Is there a way this could work for all future rotations without using if else for all 4 rotations?

How to simulate car drivetrain (in Unity)? One of my hobby projects involves cars. Up until now I had a quick and dirty "one class" implementation of engine gearbox wheels, but I thought that this is ugly, and I want to go a bit more realistic. Sadly I couldn't find much on Google (either wrong search terms or there really isn't anything that is what I want). It seems like Setup in scene Four wheelcolliders attached to a big boxcollider. Things that I want in the system Separate classes for engine, clutch, gearbox, differential and wheels (and whatever else does stuff with torque). Throttlecontrol with revlimiter (works!), steering (works too!), brakes (not yet made, but also not very complex and will likely work). First thing I tried Mainly this rotates around how I tell the engine that the wheels are actually using or giving (engine braking) power to the system. so first I created all the classes each with their own updatemethod (not called directly by mainloop, but from a fixedupdate of a controllerclass). updatemethod of engine calculates engine torque from throttle, torque curve (animation curve) and engine friction. This is then used to speed up the virtual crankshaft which has its own inertia. But before speeding up the shaft, I decided to put some feedback torques on the engine torque, so if the wheels can't keep up, the engine can't speed up, or even slows down. Such a feedback torque is added for example by the gearbox, which in turn also has feedback forces from the differential and with that the wheels. The wheels calculate the torque needed to spin up to the speed of the shaft coming out of the gearbox and then it propagates all back to the engine over a few updates. Problem was, the torque feedback didn't really do engine braking, but catapulted it to several million RPM in a split second. Dividing the feedback torque by 1000 did work, but then the car didn't move at all. So this is fail number 1. Fail number 2 Okay screw this, I thought, and tidied up all the stuff. This doesn't use several updatemethod anymore, but recursive updating. Basically I call update on the engine, which in turn then calculates what torque it has available. With that it tells the transmission that it has t torques at r RPMs. The gearbox changes the values according to the current gear and then again puts the values into the differential. The differential SHOULD split the torque between its outputs. To do this I calculate how much torque the output (in this case wheels) would need to speed up to r RPMs. I do this for each output and make a list of it for each output. I also save the sum of these values. With this I can get a value of 0...1 for each output, that determines how much torque each output gets in its updatemethod. Its basically an intelligent differential that gives the output which needs more torque, more torque. I guess modeling a real differential would involve some more complex stuff. Now the torque is at the wheels and gets put into the motorTorque property of the wheelcollider. Up until here it works. If I throttle up and then let go of it the wheels start turning backwards. It's basically another feedbackloop just like with the first try. So also fail And fail 3 Instead of returning the torque that's left, I tried backpropagating the RPMs to the engine instead. So I apply torque, and get RPMs back. But again everything tries to move the car in the opposite direction that I want it to go. Here is where I'm out of ideas. I want a relatively realistic drivetrain, that is modular and can do enginebraking. A bought asset will most probably not solve my problem, and I also want to understand how it works, and not just use it. Does anybody have experience with how to properly model a drivetrain? If I forgot to mention something, please ask.

How should asset bundles be divided? The only way to load an asset from an asset bundle into memory is to load the entire thing, decompress and pull out the asset you want, then unload the entire thing, except the assets you want. This seems impractical for sharing assets between bundles. For example, if asset bundle A wants a single asset from asset bundle B, it must load all of B, pull out the asset, then destroy B. The alternative to this is to extract the shared assets and create a new bundle call asset bundle C. The problem with this is that B must have been designed this way before being built, which it won't be if it was built before A (it has to be since A depends on B). Using the resources folder results in a huge blob of bytes that, from what I understand, cannot be changed after build, and is certainly not differ able for patches. Putting the pros of asset bundles and the resource folder together, I figure that having an asset bundle for every asset is the best of both worlds. Is there problems with this? Is my understanding of asset bundles or the resource folder flawed?

Unity Record real time game play in high quality using offline rendering? I'm looking to record Unity gameplay at really high quality (360 Stereo 8k 120 fps). I can't do this in real time due to the GPU resources required so I need to do offline rendering (frame perfect rendering). The problem is offline rendering by its nature doesn't accept user input, so I can't record live gameplay footage. I'm looking for a solution that lets me record live gameplay and then render it out at this higher quality. I considered recording the user input or the gameobjects properties and then playing them back while rendering the footage. I tried a number of assets like Ultimate Replay 2.0, Record and Play, GameObject Recorder, even tried Unity Recorder to an animation but none of them record all of the changes to components on a gameobject. I think I'll have to write my own code, although I'm not sure what the best method would be, I'm reluctant to sink to much development time into this if there's an easier solution that I've overlooked? Initially I'm looking for a solution that works inside the Unity editor but would love to be able to give this ability to end users.

How can I launch Visual Studio via a double click on a C script in Unity? This is my first time using Unity and I am following the tutorial for the 2D RogueLike Game. Everythings seems to be working properly, apart that I cant get Visual Studio to launch, if I'm double click my c scripts. What I have tried so far Checked my preferences, that External Script Editor says "Visual Studio 2017" Reinstalled Unity and Visual Studio. Unity Version 2019.3.0a2 Personal Hope somebody can help me. Additional information After double click, nothing seems to be happening, even my mouse doesnt show a load icon When I create a new project, the bug (dont know if bug, or my fault) is still there. I can open the .sln file from my project in Visual Studio. Visual Studio can even autocomplete unity based code then, before it was a "miscellaneous file" and didnt autocomplete code like for example "Transform" or "Rigidbody2D".

Camera Movement Snap Camera back to origin in relation to the player object I am trying to implement camera movement like it is done in Guild Wars 2. Scenario is when A and D keys are pressed, the player rotates right left and the camera follows and stays behind the character player like this (Starts at 23 seconds) https www.youtube.com watch?v XkHJ2uSrLjE I can get the basic working fine, and I did it this way private void KeysRotateCameraAndPlayer() float keysOrbitingSpeed 120 this.player GameObject.FindWithTag("Player").transform if (Input.GetKey(KeyCode.A)) Debug.Log("Rotate Left") CenterPoint.eulerAngles new Vector3(0, 360 Time.deltaTime keysOrbitingSpeed, 0) player.eulerAngles new Vector3(0, 360 Time.deltaTime keysOrbitingSpeed, 0) else if (Input.GetKey(KeyCode.D)) Debug.Log("Rotate Right") CenterPoint.eulerAngles new Vector3(0, 360 Time.deltaTime keysOrbitingSpeed, 0) player.eulerAngles new Vector3(0, 360 Time.deltaTime keysOrbitingSpeed, 0) Now the next part I am trying to achieve , when the camera is rotated orbited around the player using the mouse and is left in a position that is not the origin i.e behind the player (in relation to player) when A and D keys are pressed, what happens in GW2 is the camera seems to snap back to the origin and then continue to follow the player from the back ( or its relation origin with regards to the player Object if that makes sense) This is what the game does (which I hope to achieve) https www.youtube.com watch?v qTTDaeuHl80 so at present moment with my current code https www.youtube.com watch?v a53lZ 0BDtg camera and player will continue to rotate (with A and D), from where the camera was last left during orbit. How can I add to this, to force the camera to snap back to origin like they have in Guild Wars 2?

How to obtain a camera stream from Unity without rendering it to the player's screen? I'd like to stream the output of two cameras to a separate process. Right now, it looks like the best way to do that is to grab the rendered camera views from the screen via platform specific screen capture hooks then compress them real time with h.264. Is there a way to grab the input of the cameras within unity and avoid rendering them to the screen? One solution I'm considering involves using Unity's multiplayer capability to run the game on a separate machine and grab it from that screen buffer, unbeknownst to the player.

Accesing child GameObjects of GameObject I have already tried really much with all "GetChildren" and similar functions, but I haven't found out how to do it yet. I have a GameObject named "koffer". I have added several other GameObjects as children to it. I have added a script to "koffer" in which I try to retrieve the children. In this script I have stated this line string sThis this.name just for testing. "sThis" becomes "koffer", so it looks perfectly fine. foreach (GameObject g in this.GetComponentsInChildren lt GameObject gt ()) doesn't retrieve anything. So obviously I'm not doing it correctly. However this doesn't retrieve anything. Is this not the correct function for such a case? Is there any built in function to retrieve theses game obects? I have found several custom made functions from some years ago, and I don't know if they are still needed or if Unity has integrated some functions for that. What really bothers me is that there are so many custom made functions that deal with "Transform" instead of "GameObject". Why would somebody need Transform instead of GameObject? Thank you.

How to properly interact with game objects in Unity3D? I am trying to make a game where player will be placed in the scene and the goal is to explore it. He can interact with game objects that player can find in the environment, like picking object, examining, dropping and putting back. Basically it is something like first person exploration... So the problem is how to properly implement code regarding interaction. One way I see and saw it on the internet is Raycasting. So the idea would be to in Update() method place Raycast fire code and see what it hits. Also all game objects with which player can interact are placed on separate Layer and also limit length of Raycast (which is obvious thing to do as player cannot interact with objects that are like 10 meters from him)... So as I understand, game objects should have at least some kind of collider (I know box and sphere colliders are simple, but sometimes I will need to use more complex one)... That being said, I wonder is this right approach Separate layer for interactable objects Raycast that checks objects in that layer Raycast length limited to like 1 meter This approach should not be that much CPU consuming or is there any other way? I am also thinking to putting some invisible box area (trigger) where raycasting would make sense, but I am not sure will this be overhead or not.... So, at the end what would be the right approach to this?

How can I set up a 3D camera for a top down game like Enter the Gungeon? DodgeRollGames, the developers of Enter the Gungeon, tweeted that the game was in fact made in 3D They tried to explain how they set their camera in this reddit post. Basically what they said was so the walls are tilted 45 degrees toward the camera, and the floors are tilted 45 degrees away from the camera, meaning that each should experience sqrt(2) distortion because of the additional length along the z axis. However, the vertical (y axis) floor length shouldn't be perceptually changed. The camera is not tilted at all. Camera 0 degree tilt. Walls 45 degrees tilt. Floor 45 degrees tilt. My question is What do they mean by quot However, the vertical (y axis) floor length shouldn't be perceptually changed quot . If I tilt the walls and floors by 45 degrees and 45 degrees as said, the sqrt(2) distorted walls (the walls have Z depth and are perpendicular to the ground) line up nicely, but the ground gets distorted (obviously). So I distort the ground tiles by sqrt(2) but this essentially stretches the ground by 40 so every vertical movement now has to be increased by 40 . Can somebody explain what's going on? Any help would be highly appreciated.

Why do asymmetric specular highlights appear in a scene with only ambient lighting in Unity? I have a scene in Unity (2019.3.0f3 Personal) using the High Definition Render Pipeline. There are no lights in the scene, and Baked Global Illumination is disabled. The skybox is a GradientSky. By all means, the lighting in the scene should be absolutely uniform, but instead there is a gradient from one side to the other. This is what the scene looks like Though the effect is faint, you can see that the right side of the plane is slightly lighter than the left. The ground shader is HDRP TesselationLit, and by bringing the Smoothness Remapping to max I can exaggerate this effect, as shown below. This is why I am under the impression the effect is specular in nature. Interestingly, if I switch the camera to the Isometric mode, the effect disappears Finally, the effect appears to occur in world rather than camera space, as shown by the changes in lighting when I rotate my camera in increments of 90 degrees What is causing this effect, and how can I disable it?

I suspect the issue is that I am setting each pixel individually for my Texture2D private static Texture2D CreateSolidTexture2D(Color color) var texture new Texture2D(Screen.width, Screen.height) for (int y 0 y lt texture.height y ) for (int x 0 x lt texture.width x ) texture.SetPixel(x, y, color) texture.Apply() return texture I have tried creating the Texture2D by resizing a Texture2D of a single pixel, but the color comes out as a translucent white, instead of the color passed private static Texture2D CreateSolidTexture2D(Color color) var texture new Texture2D(1, 1) texture.SetPixel(0, 0, color) texture.Resize(Screen.width, Screen.height) texture.Apply() return texture Why doesn't my second approach work? How can I efficiently create a screen sized Texture2D of a solid color?

How can I iterate over all entities with a particular component? I'm currently designing a game engine and want to implement my own ECS implementation, so I decided to look around for ideas. Unity has recently updated their engine and seems to be pushing towards using ECS, instead of their original components are systems design. I noticed that Unity has a method called "GetEntities", a generic method which can do something like this public struct SomeComponent IEntityComponent public string Message "Hello, World!" public struct Filter SomeComponent someComponent public MovementSystem EntitySystem public override Process() How can I accomplish something like this? foreach(var entity in GetEntities lt Filter gt ()) Console.WriteLine(entity.someComponent.Message) I like this style of iterating over entities, given a filter for a specific component they need to include. But I'm not sure how to accomplish something like this. If someone could shed some light on how something like this is even possible in C that would be great!

Why does WorldToScreenPoint return "strange" results? I would like to show a menu to the right side and at the same y coordinate as a certain gameobject (shown as a green cube in the screenshot). Therefore I'm trying to get the screen coordinates of the object in my scene using WorldToScreenPoint. The code I'm using is this Vector3 nPos new Vector3(GlowCube.position.x GlowCube.localScale.x, GlowCube.position.y, GlowCube.position.z) Vector3 nOff Camera.main.WorldToScreenPoint(nPos) The resulting values however don't look right to me. I have created a red rectangle in order to demonstrate where the coordinates "nOff" would actually be in the screen At first I thought I get these strange results because the GlowCube is parented to the case, but since I use GlowCube's world coordinates (GlowCube.postion...) and not its local coordinates (GlowCube.localPosition...), I thought that this wouldn't matter. What am I forgetting here? Thank you!

UNITY Huge amount of GRAPHICS in RTS Tiled game after year of development and week of unsuccessful optimization I turn for a help from you, guys. So, my game is turn based strategy with hexagon map. One hexagon consists of one texture for hexagon tile type and seven subtiles, which carry spriterenderer with graphics like piece of town. So if soldier steps on the subtile, the graphics of subtile hide. On good machines like mine, if I zoom out maximally (45 orthographic size) on 1920x1080 and have visible around 18x16 tiles I get solid 160 200 FPS at MAX details, but on my laptop I barely get 25FPS on 1280x720 and LOW details. Each tile has resolution of 636x499. I have tried Simple shader on SpriteRenderer supporting transparency, just merging texture with color (This had those best results of 160 250FPS at HIGH END and 25FPS on LOW END) Creating separate material for each subtile and replacing SpriteRenderer with Quad mesh, so those subtiles are statically batched or GPU batched (but I guess they did not batch at all, because frame debugger showed that sometimes more fo the same pieces got rendered and then sometimes just one) So this is just the 50x50 game, when I start large map, like 120x100, it's not really that worse, so I think the problem is just in the graphics and not in the amount of objects. What are your suggestions I should try to get better performance on LOW END devices? Do you think that manual GPU instancing would make it faster? I think, there would be a lot of trouble maintaining which graphic to render and which not.
