Unity VR player not moving when running in device I am following Udemy tutorials for learning VR using Unity and making a game named Ninja Slash. Everything seems to be working fine in the Unity Editor Play mode but when I run my app in a real device, my player doesn't move at all. I can't figure out what is the problem here. Here is my Player script. public class Player MonoBehaviour public GameObject sword public float speed 4.5f public float walkingAmplitude 0.25f public float walkingFrequency 2.0f public float swordRange 1.75f public float swordCooldown 0.25f public bool isDead false public bool hasCrossedFinishLine false private float cooldownTimer private Vector3 swordTargetPosition Use this for initialization void Start () swordTargetPosition sword.transform.localPosition Update is called once per frame void Update () if (isDead) return transform.position Vector3.forward speed Time.deltaTime transform.position new Vector3( transform.position.x, 1.7f Mathf.Cos(transform.position.z walkingFrequency) walkingAmplitude, transform.position.z ) cooldownTimer Time.deltaTime if (GvrViewer.Instance.Triggered ) RaycastHit hit if (cooldownTimer lt 0f amp amp Physics.Raycast(transform.position, transform.forward, out hit)) cooldownTimer swordCooldown if (hit.transform.GetComponent lt Enemy gt () ! null amp amp hit.transform.position.z this.transform.position.z lt swordRange) Destroy (hit.transform.gameObject) swordTargetPosition new Vector3 ( swordTargetPosition.x, swordTargetPosition.y, swordTargetPosition.z) sword.transform.localPosition Vector3.Lerp (sword.transform.localPosition, swordTargetPosition, Time.deltaTime 15f) void OnTriggerEnter (Collider collider) if (collider.GetComponent lt Enemy gt () ! null) isDead true else if (collider.tag "FinishLine") hasCrossedFinishLine true Here is the screenshot for hierarchy view.

Reading text from file changes the text? I'm currently trying to load a simple text file and filter it by a certain string. In the text file I'm using a new line for each value and sometimes use a " " to make things easier to read for me when viewing the .txt file. Now, when I load the file and split it by new lines I end up with a list of substrings, each representing a value I need. Plus, all the "seperators" I put into the file. My goal is to clean the list from all the seperators and basically just remove them from the list. However, RemoveAll does not work and I found out that the strings containing " " are not really " ", but something else, because using string.Equals(" ") fails on them. Somewhere when reading the data or splitting it, something happened to those parts, but I can't figure out what's happening. Here's the code void Awake() fileLines new List lt string gt () TextAsset txt Resources.Load lt TextAsset gt ("SubjectPages test") fileLines new List lt string gt () fileLines txt.text.Split(new string " n" , System.StringSplitOptions.None).ToList lt string gt () fileLines.RemoveAll(x gt ((string)x) "") fileLines.RemoveAll(x gt ((string)x) " ") for (int i 0 i lt fileLines.Count i ) Debug.Log( fileLines i " " ( fileLines i .Equals(" ")) " " ( fileLines i " ")) Removing empty lines with RemoveAll seems to work fine.

2.5D game vector choice I'm developing 2.5D game (3D assets, 2D gameplay). Since gameplay takes place on horizontal plane, majority of game objects have y component equal to 0. Most of my algorithms work on Vector2s, since these calculations obviously make more sense (and are a little bit faster, I guess). This makes field for hard to catch bugs, since Unity allows transparent conversion from Vector3 to Vector2 via cutting off z component. Since I'm still in a stage in which I can change calculations quite easily, my question is which approach will cause me the least trouble? Current Gameplay on XZ plane, custom conversion from Vector3.XZ to Vector2.XY Gameplay on XZ plane, calculations on Vector3.XZ (and making sure, that y is always 0 otherwise some of calculations may be erroneous) Gameplay on XY plane (that may cause some problems in editor I guess) and automated conversion from Vector3.XZ to Vector3.XY Gameplay on XY plane, calculations on Vector3.XY (though I see no benefit over solution 2) Or is there some other approach I may take?

How can I have realistically bending flexing paper? I am a new hobbyist to Unity and I working on a game where the player goes around picking up clues in the form of paper notes to solve a mystery. So far, thanks to the help I got here, I was able to animate a note made from a UI canvas and an image in game world to fly and rotate to align itself in front of the first person camera. Although, it looks nice, it still looks like a rigid plank of wood rather than a piece of paper. Is there a way I could bend flew distort the canvas to give the illusion of a piece of paper rather than piece of wood? Is it possible to bend a canvas or should I go towards another solution, like using an actual plane or quad during the animation effect?

2D procedural veins cumps of weighted ores rocks I'm evaluating methods for generating "clumps" or "veins" of rocks in a 2D top down procedural game. Obviously the most common suggestion is to use various types of noise, but I feel like noise (alone) won't achieve what I'm after. I've used a combination of voronoi and perlin noise because it's easier to generate "regions" of different noise. I can more easily turn these areas into "veins" of rocks or something than I could be using a "heightmap" alone heightmaps tend to be more swirly cloud like. With a high threshold and some rounding, I can turn this into a mask that works well for veins Changing the spacing and scale is as simple as toying with the math threshold. The difficulty lies with choosing which "rock" (or "ore") will fill each vein. Primarily, this is thanks to the fact that my rocks are weighted. Veins of rare rocks should not be common. I currently map the original voronoi cell value to a specific rock, which forces each vein to be a single type, but can't be weighted. As you can see in picture 1, there's a fairly even distribution of each shaded area. So either, I need a new way to choose a weighted random rock type for each vein, or I need a new way to place veins. Minecraft is a good well known example of what I need, except I work in 2D Regularly distributed ore veins Veins of common ores are found more often and are typically larger veins Veins of rare ores are harder to find, and are smaller in size Noise alone just can't seem to produce these values. What else can I try?

Unity OnTrigger detection issue with Child of Prefab I'm trying to make a set of tiles on the floor of my 3d world visible only when the Player is nearby them. This will work as single tile prefabs. Just not if I set them within an empty parent gameobject... which is what I really need, ideally, for the sake of game performance. Once I put them inside the empty parent gameobject, OnTrigger stops working or even registering (debug.log doesn't show anything). Does anyone know the correct way to access and switch the MeshRenderer on off via OnTrigger (or OnCollision might be even better... I've tried and same issue) when I have a LevelManager that loads all my game objects at runtime? The Level Manager instantiates a prefab (clone), which has an empty gameobject that's holding the tiles as children? Code I've tried and that's not working so far public class CubeVis MonoBehaviour Use this for initialization void Start() Update is called once per frame void Update() private void OnTriggerEnter(Collider other) Debug.Log("hit") if (other.gameObject.CompareTag("Cube")) Debug.Log("hittt") other.gameObject.GetComponentInParent lt MeshRenderer gt ().enabled true other.gameObject.GetComponentInChildren lt MeshRenderer gt ().enabled true other.gameObject.GetComponent lt MeshRenderer gt ().enabled true Inspector Hierarchy info as requested

Unity 5 Place objects in game to closest gameobject I am making a puzzle game in unity3D 5 for school and one of the puzzles is this The player (third person) can pick up certain objects (4 objects) and has to place them inside holes in a wall in a specific order for a door to open. I have 4 empty gameobjects named as slot001, slot002, slot003 and slot004 at the right positions at the holes in the wall. When the player has an item held and a certain button is pressed I link the transform of the object to the transform of the empty gameobject. The problem is that the objects transform has to link to the transform of the closest gameobject. So when you stand in front of the slot002 gameobject the objects transform should link to the transform of slot002. The same goes for slot 001, 003 and 004 ofcourse. I am not sure how to do this. I put the 4 empty gameobjects (slots) in a list. I know of the Vector3.Distance() function and I tried using that to check for the closest distance with Mathf.Min() but I couldn't quite get it to work. Any help or a nudge in the right direction would be appreciated! Thanks.

How to organize the highlighting of a 3D object with which contact occurs? I want to repeat a certain "Select () Deselect () ", as shown in the screenshot. Prompt with advice how to implement it or what you need to read to implement this feature. I tried to found something similar to what I want to do. PlayerInteraction.cs from Farm Alarm game by Brackeys private void OnTriggerEnter2D(Collider2D col) if (target ! col.gameObject amp amp target ! null) Deselect() target col.gameObject SeedBarrel barrel target.GetComponent lt SeedBarrel gt () if (barrel ! null) barrel.Select() SpriteRenderer srs target.GetComponentsInChildren lt SpriteRenderer gt () foreach (SpriteRenderer sr in srs) sr.color new Color(1f, 1f, 1f, 0.9f) private void OnTriggerExit2D(Collider2D col) if (col.gameObject target) Deselect() target null void Deselect() SeedBarrel barrel target.GetComponent lt SeedBarrel gt () if (barrel ! null) barrel.DeSelect() SpriteRenderer srs target.GetComponentsInChildren lt SpriteRenderer gt () foreach (SpriteRenderer sr in srs) sr.color Color.white But if I understand right it's way for 2D.

(Unity) Is there a way to automatically create a material for each texture and assign the texture to it? I have imported hundreds of textures in my Unity project, and I'd like to create a material for each of them. This would obviously take a lot of time, so how would I go about doing this automatically? These are just basic textures that I want to assign to albedo on the standard Unity 5 shader. No need for normal maps.

Scale object based on another object's position Despite an hour or so of Googling I can't seem to figure out how to calculate the scale factor based on distance. Here's the illustration of my problem. I've tried manipulating the x values and such, but until now I still cannot figure it out. Here's the snippet Vector3 v3Scale frontWall.transform.localScale frontWall.transform.localScale new Vector3(v3Pos.x 2.0f , v3Scale.y , v3Scale.z) Any ideas? Thanks in advance! UPDATE if(getTarget.CompareTag("LeftRightWall") amp amp getTarget.transform.childCount 1) float translate getTarget.transform.position.x getTarget.transform.GetChild(0).gameObject.transform.position.x Debug.Log("value " translate) foreach (GameObject frontWall in GameObject.FindGameObjectsWithTag("FrontWall")) Vector3 v3Scale frontWall.transform.localScale float scaleFactor translate frontWall.transform.localScale.x frontWall.transform.localScale new Vector3(translate , v3Scale.y , v3Scale.z) v3Pos.z getTarget.transform.position.z v3Pos.y getTarget.transform.position.y getTarget.transform.position v3Pos getTarget.transform.GetChild(0).gameObject.transform.position new Vector3( v3Pos.x, v3Pos.y, v3Pos.z) The LeftRightWall is the ones that I drag on the picture, with another vertical line as its child. The FrontWall is the horizontal line that is stretched when the LeftRightWall is dragged. Hope its clear enough. Thanks UPDATE This is the closest one from what I'm trying to achieve... (( Here's the code float translate getTarget.transform.position.x getTarget.transform.GetChild(0).gameObject.transform.position.x Debug.Log("value " translate) foreach (GameObject frontWall in GameObject.FindGameObjectsWithTag("FrontWall")) Vector3 v3Scale frontWall.transform.localScale frontWall.transform.localScale new Vector3(translate v3Pos.x, v3Scale.y , v3Scale.z) UPDATE This is what I'm able to do so far, thanks to the answer below. However I still don't know why the other side of the panel is behaving like that. The scale of horizontal lines also shrinks when I click on the vertical line. This is the updated code ray mainCamera.ScreenPointToRay(Input.mousePosition) float dist plane.Raycast(ray, out dist) Vector3 v3Pos ray.GetPoint(dist) if(getTarget.CompareTag("LeftRightWall") amp amp getTarget.transform.childCount 1) float translate getTarget.transform.localPosition.x getTarget.transform.GetChild(0).gameObject.transform.position.x Debug.Log("value " getTarget.transform.GetChild(0).gameObject.transform.localPosition.x) foreach (GameObject frontWall in GameObject.FindGameObjectsWithTag("FrontWall")) Vector3 v3Scale frontWall.transform.localScale float scaleFactor (translate v3Scale.x) frontWall.transform.localScale new Vector3(v3Scale.x scaleFactor, v3Scale.y, v3Scale.z) v3Pos.z getTarget.transform.localPosition.z v3Pos.y getTarget.transform.localPosition.y getTarget.transform.localPosition v3Pos getTarget.transform.GetChild(0).gameObject.transform.position new Vector3( v3Pos.x, v3Pos.y, v3Pos.z)

Unity GL.Lines going over 3D models I'm drawing lines using GL.lines but they disregard the zbuffer and always appear over my model. I found this thread http answers.unity3d.com questions 434827 gllines over game objects.html and decided to give the answers a try, but it didn't seem to fix things. For now I'm using the shader found in that thread, here is the rest of the code void OnPostRender() GL.PushMatrix() testMaterial.SetPass(0) GL.Begin(GL.LINES) for (int i 0 i lt basicMesh.linePoints.Length i ) GL.Color(new Color(1,1,1,1)) GL.Vertex(basicMesh.linePoints i .point1) GL.Vertex(basicMesh.linePoints i .point2) GL.End() GL.PopMatrix() Any advise on how to make the lines not go over my 3D models?

Full Engine or Not C Programmer Trying to get into Game Development I'm a fairly experienced programmer, and I want to try out doing some game development. However, I am unsure of whether or not to use a full engine like Unity or just start with something like OpenGL. How much flexibility extensibility do you use going with Unity. I know it can be used with minimal coding, but if you can write your own code, will it constrain you later down the line? For my first project I want to just build a simple tile based rpg and build it up to something larger. Any advice is welcome.

In Unity, is there a difference between Vector3.down and Vector3.up? I've noticed numerous tutorials and examples using something like "transform.up 1" or " Vector3.up" instead of simply saying "transform.down" and "Vector3.down". Is there a good reason for this, or is it simply a style difference? I'm specifically thinking about downward raycasts, if that matters at all.

Find References In Scene of scriptable object unity asset shows incorrect results I'm trying to work out why my game is loading a large sprite atlas that I don't think it should be. The snapshot view of the profiler shows that the atlas is loaded. The references pane shows that it's loaded through a scriptable asset object. That object does indeed reference the sprites in the atlas but I don't think the object is referenced in the scene at the moment. The game boots to this scene, so the atlas should not be loaded. I've replicated this profiling on both the editor and on android, so it's not an editor only thing. When I right click on the scriptable object in the project view, while the game is running, and Find References In Scene, it shows a few game objects. None of these objects seem to reference the scriptable object. None even have monobehaviours with fields for this type of scriptable object. Some are new UI button objects, that have Canvas Renderer, Image and Button scripts only. None of which could be referencing this scriptable object. Has anyone seen this behaviour before? What's going on?

How do I keep a rigidbody from making unnecessary collisions on smooth surfaces in Unity3d? I have been having trouble with a custom character controller I am making. The root of the problem lies with collisions. I am trying to make movement code, but I have a problem with ground movement. Pay attention to this gif. It might be hard to notice due to the low frame rate, but the collider registers collisions with objects (in red) that do not point out of the ground. They share the same y position as the ground. I've printed the normals of the collisions, and there are a lot of normals that are perpendicular to the normal of the ground (which is causing the rigidbody to get stuck). The problem lies with collisions in unity. If I were to print the y position of the bottom of my collider, it would be just a tad lower than the y position of the ground. The collider actually rests below the ground by an almost negligible amount (which is why it doesn't always collide with these objects). Here is what I have tried I created a function that runs at the beginning of every FixedUpdate() that uses current collisions to change the y position of the rigidbody. It only runs on collisions that would ground the player (meaning that they are below the collider). The problem with this approach is that the same issue can occur with walls, meaning that the collider can get stuck on walls. I cannot create another function that would do the same for walls for various reasons. Here is what would fix the issue I need help figuring out how I can make collisions more discrete in unity. Colliders rest slightly below objects when ontop of them. They can also "sink" just a little into walls. In other words, colliders can rest into other colliders, and I need this to stop. Any help is appreciated. Thank you.

The asset also came with a few animations like blinking, jumping, etc. How do I apply these? I'm new to unity and game development(started about a few days ago) so please help even if this may sound like a really dumb question. I use Unity BTW if it changes what the answer would be.

How should I store trading cards? I'm working on a Magic esque TCG in Unity. Currently, the cards themselves are all prefabs I have a Satyr Archer prefab, a Candle Wisp prefab, etc. This works fine for now, since I only have a few cards, but by the time I get to several hundred, I feel that this may become unwieldy. Are prefabs a good way to store a large list of cards? Should I be making those prefabs using an XML document and a script?

Unity assembly files missing from "Temp bin Debug" I'm trying to use VS Code on a Mac with Unity and C . When I try to open a Unity project in VS Code, it can't load Assembly.dll files from few locations which are defined by default in .csproj files "Temp bin Debug ". When I check the Temp bin Debug paths, while Unity is running, they are empty they doe not contain the assembly files, where I assume they should. The files are in "Library ScriptAssemblies". Moving them is not an option, because I would have to do that manually every time I change sth. in any script file. Changing the path in the .csproj files is also not a good idea, because those files get rewritten every time you open a project in Unity.

Instantiated object can't be parented I'm writing a script (in C ) which, on mouse down, will spawn a gun and parent it to a game object. But for some reason the gun is instantiated just fine, but it doesn't parent. I have an empty game object called "Hands" and I'm trying to have the gun become a child and be moved to the position of "Hands". To test what was going on I made two scripts, one which would parent the object upon pressing P, while the other script would just instantiate the item on mouse down. It worked, I first spawned the gun with mouse down, and then pressed P and it was parented. So my only guess is that you can't instantiate and parent in the same script all at the same time. I have absolutely no clue what's going on, so I really appreciate any help I can get. This is my code using System.Collections using System.Collections.Generic using UnityEngine public class GiveWeapon MonoBehaviour public GameObject Weapon public GameObject Hands void OnMouseDown () Instantiate(Weapon) Hands GameObject.Find ("Hands") Weapon.transform.parent Hands.transform Weapon.transform.position Hands.transform.position

How to return the scene view camera to the default view By the quot scene view camera quot I don't mean a GameObject with a Camera component, I mean the camera used to draw the Scene window in the Unity editor, controlled by this quot Scene Gizmo quot widget The default view shows an almost isometric perspective, where all three X Y Z axes are visible. But when I clicked the green Y cone, my view changed to look straight down the Y axis, and I can't seem to return to the 3 axis view. Clicking the other cones on this widget just switchest to look along the X or Z axis instead, and clicking the cube in the middle or the quot Top quot label just toggles between orthographic and perspective projection. How can I get back to the default 3 axis view?

What's the better approach, running multiple server builds on one instance or running one server build and managing matches in different rooms? We are building a racing multiplayer game using Mirror and Unity and we've been able to successfully run the authoritative server on AWS Gamelift and Playfab so far. Both providers are with the flexibility of running multiple server builds and mapping with different ports. So I think running multiple server build for different matches on one instance is a bit expensive in terms of server usage as compared to running one server and managing multiple matches in different rooms. But overall it seems to be a safer option to go with since build crash and similar issues will only happen on one match and other matches (servers) will be running fine on the same machine and also it's a bit easier to handle and scale. What's your opinion on this? It might be useful if you share any blog or resource to look at for scaling and managing servers on gamelift playfab. thanks!

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".

I understand that you can compile the C code to a shared library and use it in Java (for Android) in ObjectiveC (for iOS) to enable Unity on multiple platforms, but you cant use shared library on JS. Does Unity do language to language translation from C to JS to enable Unity on Web? As I understand now starting from Unity 5.0 it even doesn't use Unity Web Player.

Instantly snap into specific directions? In my 2d setup, I want the player to constantly move in a specific direction at a set speed. It's similar to "Snake" in that you can only move in four directions and you can't stop your movement. Right now, the way I do this is by having a char variable "direction", which can either be u, d, l, r (take a guess what those stand for). Based on those letters, I use GetComponent().MovePosition and increase decrease the position on the x or y axis. Is there a better way to do this? I would prefer if I could just enter the degree (0, 90, 180, 270) to make the player move in the right direction. I tried AddForce but I couldn't get it to work. Side note it's important for me that I can set the direction without player input, as there are some objects that force the player into a different direction. Edit As the tag would suggest, I'm looking for a Unity specific answer, as I'm not sure which function would best suit my needs.

I tried blending this effect with another effect that just fades the object from the bottom up but this does not create the effect I am looking for ( 1 is the fade effect, 2 is the two shaders blended together) The end effect should look something like this How can I achieve this effect? Answers do not have to be specific to Unity and a good answer should include the thought process to creating this effect, not just code or pictures of a shader graph.

Change Time.timeScale during an animation event Unity I have an animation. A few seconds after this animation starts I set an animation event that is correctly being triggered. This animation event calls a method where I am trying to modify Time.timeScaleand set it to 0.05f. This event is calling the following method public void Slowmotion() Time.timeScale 0.05f Time.fixedDeltaTime Time.timeScale 0.02f But this Slowmotion method is not working. Any ideas on what may be happening?

Screen record in unity3d How to do screen record in unity? I want to record my screen(gameplay) during my running game. That should be play stop , replay , save that recording on locally from device, open load from my device (which is already we recorded). In my game one camera which can capture native camera, and one 3d model. I wish to record that both and use my functionality whenever i want. Thank you in advance.

Causing Update loop with Coroutine Unity Total Noob Alert! lt 7 days with C and Unity My Win Game screen becomes SetActive and my Player is SetActive false when you are standing in a trigger and crouch. That all works fine except you cant see the crouch animation because he is IMMEDIATELY SetActive false. I tried to delay this by creating a coroutine. The problem with that is this is all happening in the Update function (or whatever it's called) because of the getkeydown for crouch. That gets called once per frame so my coroutine is trying to go off once per frame. I tried creating a bool called isCoroutineStarted and set it to false and then set it to true in the Coroutine to break the loop but that didn't work either. Don't know what to do so I reverted it back to before where it doesn't show my crouch animation. Here's my script (It's attached to a Game Object with the trigger) using System.Collections using System.Collections.Generic using UnityEngine public class xxxxxx MonoBehaviour public bool xxx false SerializeField private GameObject youWinUI SerializeField private GameObject player Determines whether or not the player is standing on the xxxxx void OnTriggerEnter2D (Collider2D other) xxx true void OnTriggerExit2D (Collider2D other) xxx false Turns on Win screen and makes player disappear when crouch on xxx void Update () if (Input.GetKeyDown (KeyCode.S) amp amp xxx true) youWinUI.SetActive (true) player.SetActive (false) P.S. ignore the x's no stealsies lol. Also this piece of script works as intended I just want a delay so you can see the crouch animation.

StartCoroutine from other MonoBehaviour is not working I am trying to replicate the model of Unity documentation about coroutines, but I want to partition it in another class I have these two public class A MonoBehaviour void Start() print("Starting " Time.time) B test new B() StartCoroutine(test.WaitAndPrint(2.0F)) print("Before WaitAndPrint Finishes " Time.time) public class B MonoBehaviour public IEnumerator WaitAndPrint(float waitTime) yield return new WaitForSeconds(waitTime) print("WaitAndPrint " Time.time) It prints, ignoring the coroutine Starting 0 Before WaitAndPrint Finishes 0 The two methods work well in the same class.

Help with NPC following the player in a sidescroller I'm a beginner with C and am having a bit of trouble coding an NPC that follows the player in a 2D sidescroller. The player has two speeds, a walk and a sprint. I have a very basic companion follow script but it's only set on one speed, and if I increase the speed so that the NPC will keep up when the player sprints, the NPC jitters when it follows the walking player, which makes sense. I'm just wondering if there's a way in which the NPC can dynamically follow the player in the exact same speed as the player so that this issue doesn't arise. I figure this would inquire an entirely new script, but that's fine. Again, I'm still new to all this, so any help would be greatly appreciated! Thanks! using System.Collections using System.Collections.Generic using UnityEngine public class CompanionFollow MonoBehaviour public float speed public float stoppingDistance private Transform target Start is called before the first frame update void Start() target GameObject.FindGameObjectWithTag("Player").GetComponent lt Transform gt () Update is called once per frame void Update() if(Vector2.Distance(transform.position, target.position) gt stoppingDistance) transform.position Vector2.MoveTowards(transform.position, target.position, speed Time.deltaTime)

How would I use an object from another animation in Unity? So I have two different .blend files with two different animations. Let's call my aiming with a gun animation animation A, and my other .blend file with idle, run, and jump animations animation B. If I wanted to play the aiming clip from animation A with the Animation B animator, it just looks like my character wants to shake hands, since the gun doesn't appear in the animation. The aiming animation works if I play animation A with animation A's animator. How would I use the gun object from animation A when playing animation A in animation B's animator? Here is an image of what the animation looks like in the import settings (what i want) and in the actual game (what is happening which I don't want.) The top image is what I want and the bottom image is what is happening. Thanks in advance.

Animator.SetBool am I supposed to call it only when its value changes? I've searched around the web for a while, but didn't manage to find anything about it. Despite using Animator in several projects so far, I've never been in this exact situation, so I'm unsure what to do. Does calling Animator.SetBool have any performance issue, so that I'd better call it only when its value has changed, or when its value doesn't change it's so quick that I can call it every frame? Keep in mind that, due to the nature of this question, I don't care if it's slow when I change its value, I only care if it's slow when it's false and I call it to set it to false again (same thing for true ofc).

Physics2D.Raycast not hitting any colliders I am making a topdown 2d game and want to get the x,y of mouse clicks so I can move the character to that location. I am writing a CharacterController script which performs the mouse click check and raycast in the Update function void Update () if (Input.GetMouseButtonDown (0)) RaycastHit2D hit Physics2D.Raycast(Input.mousePosition, Vector2.up) if (hit.collider ! null) Debug.Log (hit.point) This runs whenever I click the mouse, but the if(hit.collider ! null) condition is never met. I've looked around for other solutions, such as Unity Raycast not hitting to BoxCollider2D objects, but when I change my code to the one used in that answer RaycastHit2D hit Physics2D.Raycast( Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector3.back ) then the if(hit.collider ! null) block is always true, even if I click on empty space, and it always returns the same coordinate. To illustrate this, here is a video of me clicking the game view. The green area has a 2d box collider that is very closely mapped to its boundaries. You can see that the logged hit.point is always the same. video is here https i.imgur.com uhNp8wC.gifv screenshot

How To Create A Dynamic 2D Rope In Unity? I'm trying to create a 2D rope in Unity that is fixed at one end and other is moving up and down to pick up objects just like a crane. I've tried adding a cube and making more instances of it, adding a parent child relation and hinge joint between them when I press the Down arrow. It worked, but when I tried to move them sideways a big noise is generated. I then tried with a spring joint, but that didn't work.

Same dimension feel no matter what FOV Does anyone know a formula, way, ... to make a FPS player feel like an object has the same size on different FOVs (given that it's at the same distance of the player, of course)? I know that this can't be done perfectly, because of the distortion various FOVs cause and the position of the object (near the edges of the FOV more distortion). Let's ignore these distortions, and aim for a same size feel for objects that are directly in front of the player (so in the exact center of the FOV). To clarify things a bit further I want 1 object in my game to have the same scale feel on different FOVs, not my entire game world. I've tried giving it a percentage of the frustrum height, but that doesn't seem to give me consistent results. Note I'm using vertical field of view in my game.

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

How can I get separate caches for different coroutines? (Unity) I want to fade out an image, so I have a coroutine FadeOut(). However, I want to have a separate image each time I call FadeOut. If I try to do something like this IEnumerator FadeOut(GameObject image) SpriteRenderer render image.GetComponent lt SpriteRenderer gt () yield return null Ignoring all the color changing code which I took out, how do I make it so that I can save a separate cache for each image I add? I don't want to run GetComponent() each frame, because I'm running on mobile and because I want to think of a clever way to stash the renderer. For example, if I declare the renderer at the top like this private SpriteRenderer render and want to cache it on the first frame of the coroutine, there's the chance that calling FadeOut() on another object will change the renderer to a new object and the first FadeOut() will cancel. Can I make the method static? Will that cache a private version of renderer?

Setting object position in screen space camera I'm trying to set an Image gameobject's transform.position. My canvas is "screen space camera" because I needed to use a line renderer. However, when I set the position, say to new Vector3( 320, 240) the object (in play mode) gets positioned at 16266.44, y 15360, way off screen. I've tried to reset the localPosition and such based on some other answers but it doesn't help. What else could be translating my pixel coords? var go Instantiate(HexTilePrefab, this.transform) go.transform.localPosition Vector3.zero go.transform.localRotation Quaternion.identity go.transform.localScale Vector3.one go.transform.position new Vector3(screenX, screenY)

Using collision.contacts to determine if on a floor I'm trying to make my own first person character (because I get lost in the sea that is Unity's FP character script), and am trying to make it so it detects when it is standing on a floor. I tried using a playerController, but I've found rigidbody is just more malleable. Anyways, so I think how you'd do it is finding the direction of the contact, and if it isn't straight down, then to keep onGround as false. I'm just not entirely sure the scripting behind this, and several searches have turned up nothing. Several offered using mutliple colliders, but I would prefer to keep the number of objects, colliders or otherwise, at a minimum, considering there will be a large number of them in the scene as is. I also want something that's easily manipulable so that I can add extra features like climbing up a wall or the like, and I think that measuring the angle to the center is about as simple and easily manipulated as it gets.

Real time 3D Scene reconstruction into Physics Engine I am trying to create a game where the user scans the room using RGBD camera and reconstructs 3D scene. This scene would be integrated into physics engine, after an object recognition algorithm tells it what objects are there in the scene and of what shape and size. Finally, after being rendered in Physics Engine, user should be able to interact with the environment. I know how to do 3D scene reconstruction from images, I can figure out how to contruct objects and interact with them in Physics Engine. I know how to do object recognition, shape and size. However, I am not sure how to integrate the output of 3D scene reconstruction, Object Recognition as input to the physics engine. Any ideas would be helpful.

Hardcode per instance properties into the shader in unity I am using one of the packages from the asset store and using its Polyline feature for wire rendering. There are thousands of wires and its taking much fps Batch counts. The reason of the lack of support for static batching. Now there is a workaround suggested by the author of the package. if you don't use polylines for anything other than that, and all your shaders use the same properties, you could hardcode all per instance properties into the shader Due to a lack of shader knowledge(I am developing the knowledge currently and it will take time) I am unable to hard code the above properties I tried and here is the current scenario define int ScaleMode 1 define half4 Color (0,0,0,0) define float4 PointStart (0,0,0,0) define float4 PointEnd (0,0,0,0) define half Thickness 0.5 define int ThicknessSpace 1 define half DashSize 1 define half DashOffset 1 define int Alignment 1 HOw do i correctly hard code above values?

Model mesh overlapping while animating in Unity but not in Blender I made an FPS model in blender and created reload animation when I imported that model in Unity I saw that while the magazine ejecting from the rifle it overlapped some of the gun parts. Then I went back to the blender and changed some keyframes and positions in the blender but in Unity, it showed me the same problem. I tried many times it looks fine in the blender but in the Unity, it has the same problem.

Unity2D Child class inheriting onCollisionEnter() methods I may be an idiot for asking this but I can't seem to solve it myself, I have a GenericWeapon class which has a onCollisionEnter() method which I want applying to all child classes which inherit from it, here is the code public void onCollisionEnter(Collider target) Debug.Log("Collided with player!") if(target.GetComponent lt Player gt ()) bc2d.enabled false rb2d.Sleep() equip(target.GetComponent lt Player gt ()) My child class is the following using System.Collections using System.Collections.Generic using UnityEngine public class RangedWeapon GenericWeapon Start is called before the first frame update void Start() Update is called once per frame void Update() public void attack() and my in GameObject has the RangedWeapon class as a component however the GameObject does not seem to be picking up any collisions with the player. Could someone point out where I'm going wrong with this?

Why won't character stay at the x axis rotation I set In the inspector? Here is a snippet of my Update function, which contains everything regarding my rotations for the character Higher the Z float, the LESS of a rotation when moving Vector3 v3 new Vector3 (Input.GetAxis ("Horizontal"), 0.0f, 1.5f) A Quaternion variable named "quaternion" that's equal to LookRotation class that takes the "v3" variable Quaternion quaternion Quaternion.LookRotation (v3) The actual rotation is done using the Slerp class transform.rotation Quaternion.Slerp ( transform.rotation, quaternion, Rotspeed Time.deltaTime) When Countdown timer is done, then the animator is enabled adventureAnimator.enabled true When I put "357" on the X Axis tab of Rotation, why does it go back to 0 whenever the game starts? After some debugging I know it is because of my logic contained in my "transform.rotation Quaternion.Slerp" line of code. What do I need to change? If you need more information or need me to elaborate, please let me know.

How to Access a Field of an Unknown Class if the Field Exists It's a very poorly worded question because I'm not exactly sure how to put it into words that are of appropriate number for a title. Read on for a better explanation. (Using Unity API, C ) Basically, I have an AI class in a spaceship game. I can assign the AI a target GameObject, and the AI will look in the direction of and chase after it's target. I would like to make the AI be able to strafe in circles around the target. Since the AI always faces its target, I can simply TransformDirection(Vector2.left right) and it will orbit the target nicely, but if the target is moving it always breaks orbit. To combat this, I want to add the target's velocity to the strafe velocity of the AI. However, I have different classes for the player's ship and the AI ships whom also might be targeted by another AI. All of my ship classes have a field for the ship's velocity, but since they are different classes, I thought I may access the velocity field by doing a GetComponent() and passing some sort of predicate T has a Vector2 field named "velocity". Is there some way to achieve this?

How do I correct the turning effects on my car in order for it to turn properly? In my game, I'm currently working on a Physics based car driving game in Unity from scratch. My problem is that whenever I press the input controls used for turning, instead of turning, my car does barrel rolls in the air.

Tilemap is sent to back disappears behind background when I go into play mode or save (video included) screencap of the problem here I'm sure this has a simple solution but I haven't found it answered yet. I have two tilemaps, one a BG and one a middle layer, and everything works when I paint on the middle layer. It shows up on top of the BG. But if I save the project or open play mode to test it, the middle layer disappears. Seems like it gets sent behind the BG tilemap but the order of the tilemaps hasn't changed. Also of note is that nothing changes even if I reorder the tilemaps, and the only way I can make the tilemap quot reappear quot is by ctrl z undoing my last action. At a loss, any takers? EDIT I just realized that my video capture didn't pick up my drop down menus, but I create a new tilemap at the bottom of the hierarchy, put some assets in it, then save the project (stuff disappears) and then undo (stuff reappears).

How to get which gameobject the mouse is over in Unity? So I'm working on a simple drag n drop based trading card game for my own amusement. There is a card inspector included. What I want to achieve is to change values in the inspector (which has its own Inspector.cs, so I would change the variables in it) based on which card I hover over with my mouse. Each card has its own Card.cs attached from which I want to read the values of the current card. If I try to do this from within the Inspector.cs by something like this Name.text gameobject.GetComponent lt Card gt ().Name , then obviously it won't work, because using gameobject in the current context is not valid. So solution No1 would be to properly reference the gameobject over which the mouse is, which I don't know how to do. When I try to do the same from within Card.cs, I cannot use an event trigger OnPointerEnter and run the code through that, because I have to have a reference to the gameobject that contains that function. ( And I cannot do that in a prefab, only in gameobject already existing in the level.) So could anyone tell me how I could achieve what I want, please?

Create a 2D trail in Unity? I would like to make a trail for a pixelated snake such as this one As you can see, the cross simply repeats itself to create the snake.

How can I achieve this effect please? Thanks!

Issues with importing bezier curve animation (curve does not distort?) Hi guys i'm pretty new to unity and having a frustrating issue I've created a spear gun with an animation using a bezier curve grouped to the main gun shaft and distorted using a bone (bone relative) in blender. It works fine in blender, however when I export it into unity 5, the bezier curve does not distort and simple moves forward and back. I imported the blender model as a blender file. I have tried pairing the model components in all the ways i can think of to see if that was the problem? I have attached the blender views and animations and what it looks like in Unity. Is it an issue with unity being unable to animate bezier curve animations or the type of bone pairing i used?? unity animation, see the besiel curve simple moves forward and back instead of bending distorting to look like a rubber fitted on a real gun!

Need help with physics 2D Unity I'm making a 2D game in Unity. Basically there's just a rocket that goes where ever the user touches. With the code that i have right now, the rocket instantly rotates towards the point and moves there straight. Vector3 dir targetPos transform.position float rotZ Mathf.Atan2(dir.x, dir.y) Mathf.Rad2Deg rb.MoveRotation( rotZ) thrust 10.0f rigidbody2d.AddForceAtPosition(transform.up Thrust, transform.up) This code is placed in the Update function. I want the rocket to start moving in which ever direction It's currently facing and slowly rotate towards the point as it goes there.

Different implementation use case of component based approach Inspired by this question I made a small demo for an enemy that has a HP component. Basically there is a main enemy script and a HP script that considers you died on collision and lets the enemy script know on different ways. I could think of three different ways how to let the main script know that you died and included a basic implementation of each. The focus is more on how to let the main script know that you died. Broadcast public class EnemyBroadcast MonoBehaviour void HandleDeath() Debug.Log( quot Died via broadcast quot ) public class HPBroadcast MonoBehaviour private void OnCollisionEnter2D(Collision2D other) BroadcastMessage( quot HandleDeath quot ) Pro This seems to be the shortest code. Con IDE can't see the call and you need to know the broadcastevent Interface public interface IDeathHandler void HandleDeath() public class EnemyInterface MonoBehaviour, IDeathHandler public void HandleDeath() Debug.Log( quot Death via Interface quot ) public class HPInterface MonoBehaviour private void OnCollisionEnter2D(Collision2D other) GetComponent lt IDeathHandler gt ().HandleDeath() Pro Not possible to forget to implement methods Con Possible overhead of methods, reusibility Delegate public class EnemyDelegate MonoBehaviour void Start() GetComponent lt HPDelegate gt ().handleDeathDelegate HandleDeath void HandleDeath() Debug.Log( quot Died via delegate quot ) public class HPDelegate MonoBehaviour public delegate void voidDelegate() public voidDelegate handleDeathDelegate private void OnCollisionEnter2D(Collision2D other) handleDeathDelegate() Pro Outside objects are able to observe changes events Con more complicated to setup longer code Now the question is, what other ways are there in a component based approach, are there more pro con for each approach and when is which kind of implementation prefered over the others?

Vibration causing lag on OnePlus 6 has anyone experienced vibration causing lag on OnePlus 6 (or other device)? I'm developing a mobile game on unity and lately I have been Integrating Nice Vibrations to our game which is basically a wrapper for both Android and iOS vibration. Basically whenever vibrations become too rapid, like 10 vibration patterns second , my OP6 drops framerate from 60 to 20. This lagging happens with any game that uses a lot vibration so it can't be caused by any bug in our codebase. Has anyone else faced similar behaviour and managed to fix it?

How do I make UIText scale properly in a VerticalLayoutGroup in Unity? I have a Panel with an AspectRatioFitter on it. In there, I have a vertical layout group, with three buttons, Standard Mode, Speed Mode, Chaos Mode. I have the Layout Group's anchors set to keep its size relative to the parent Panel. The problem is that the text doesn't resize when I change the screen resolution. You can see it's cut off to say "Standard M" in the bottom image. But if I say "Best Fit", the texts aren't the same size, because the boxes are big enough to allow the shorter text to be bigger. The only way I've been able to fix this is to adjust the sizes and anchors of the text boxes by hand. Is there an automatic way to do this?

Vertex Snapping on a mesh with an armature I've made a selection of modular walls for a game i'm working on and some of the pieces have moving parts, like doors and flaps, but the moving pieces with an armature attached don't use vertex snapping like all of the other pieces and it leaves ugly gaps in the walls. I've tried everything I can think of to get them lined up, the closest I can get is lining them up by eye and this leaves small gaps when in game and isn't perfect. Does anyone know of a way to get vertex snapping to work with meshes that have an armature attatched? I've attached a picture to try and explain

Fill all unallocated space with texture I have a system of bunkers underground, and I need to fill all the free space where there are no buildings with earth. Yes, I can manually add a ground texture to the plane, but I have procedural level generation. I thought there might be some kind of filter on the camera that I don't know about. Or maybe there are some other solutions?

Is there a standard way to rig a humanoid? I am using some placeholder humanoid models for my game, which will be replaced later. I am concerned that when I replace them, they will not work with my animations, due to different rigging. Is there a standard rigging that artists use for humanoids? Such as, is there always a the same number of body parts attached in the same hierarchy, or does this vary based on the artist studio? If there is a standard, what is it? If there isn't how can I ensure that my animations and models play nice? I use Unity, if it's relevant. Disclaimer I am not an artist, and I have no idea what I am talking about. Please feel free to ask for clarification.

Using UDP vs Websockets I am running a Unity Game on a PC (for development purposes) and then on an Android phone (for production). I need to send data to the Game continuously from a WiFi enabled microcontroller (Esp32). Is it better for me to use UDP or Websockets for data transfer? What are the pros and cons of each method? In this scenario, the game device will act as a mobile hotspot while the esp32 will connect to this hotspot.

How can I easily assign an array in the inspector? If you make a public array class member in Unity, you can individually assign objects to the array in the inspector menu. It looks like this However, this is cumbersome if you you want to assign the same array to many objects. It's easy to do this programatically, but I'd rather not hard define the array in code it makes moving renaming the objects harder. If I want to pass the same array to multiple game objects, how can I do it more efficiently than dragging each individual element into the inspector?

Trying to understand exactly how the server sends data to the client to prevent malicious actions I recently started coding a game with one of my friends and he is taking care of the front end and I am doing the back end. I read many blogs articles tutorials on how the back end communicates with the client side and they all show different ways of doing this. In our game the player can move his character by right clicking where they want to go. Does this mean the movement happens on the client side or should the client send a coordinate to the server and the server checks if its valid and responds with 'move verified' which then allows the client side to carry out the action? If this is the case how does collision take place because it will have many calculations and can cause major stress on the server. but doing it client side will make it vulnerable to malicious scripts. The game needs to be in real time and 10 people will be playing simultaneously in a single match.I know the coords of all players have to be constantly sent to the client from the server so each player can see all players. We are using Unity and socket.io. We successfully got communication with one another. But I just want to make sure I am on the right track before I start going deeper into the code. I can show my code if its needed but its bare bones connections. Thanks in advance!

How to reduce the size occupied by my video animations? I have a mobile game but my build size is currently 4gb. Furthermore, it crashes on open and I suspect it has something to do with the huge build size. In my project are 10 animations made of a series of images, each one using around 250 300 images. Each one is quite large as the animation takes up most of the screen so they are high resolution. What can I do to reduce the build size? I have tried converting it into a video file and using the raw image component to display it as a movie texture, however, it seems unity doesn't support videos with alpha channels, and the alpha channel is critical to my animation. I thought about combining them into a single image, but lets be real, if each image is more than 1080p, then combining 250 300 images into a single file will be massive. So what can I do to reduce the size of the animations?

Mesh disapears before out of fov I use a C script to move the vertecies of my quad around the world space. It works perfectly fine, but when I move rotate the camera away, so it does not look at the position of the quad, the quad disappears. I cannot change the size of the quad, since that would not work with my other scritps. How can I force the camera to allway render the mesh of the quad?

Scale one object to be cover multiple other objects I have placed and aligned several objects next to each other. For the sake of understanding, lets just say I placed 10 cubes next to each other. I snapped them all together (Move V Click amp Drag). The cubes look great so far. Now I want to make a plane in front of the cubes, that has exactly the width of the cubes altogether. Now, I can place a new plane in front of the, no problem. I can snap a single edge to the cube on the most right, also no problem. But now, how can I make the size exactly the same as all the cubes together? Sure, I could eyeball it from top view, an kind of make it about the same size, but chances are, it's a little bit too short or too long. Isn't there a possibility to snap one edge, lock it, and snap another edge making the object scale automatically to the desired width?

Unity3D Creating Sharing light baked levels without updating the game I want to give myself freedom to add more levels after releasing the game. For creating levels I broke down structure and created a tilemap like a structure. here's an example I will add them up to create a level and send it to server from where I can download the JSON in game and read it at run time to place things around. The problem is I want to also use Global Illumination. What I can do is send lightmap data with created level to server and download and use it for lighting after generating level. But what If my map is huge?? I don't want to have lightmap size. The other thing I can do is create light baked prefabs, suggested by this article, https unity3d.com how to light baked prefabs on mobile. But every single object has to be attached to a surface and baked because of shadows. Is there a better approach? Thank you.

Blender rigid body physics animation into Unity? I'm stuck trying to get these cube objects to explode into chunks when destroyed in Unity. I've set up a physics sim in Blender of the effect I want, originally planning to replace the unbroken GameObjects with this fragmented one coupled with the explosion animation upon destruction. I guess it's not that simple. I've tried "Bake to Keyframes" in blender and exporting as an FBX, but Unity imports each individual fragment with its own Animator Avatar and a crazy amount of animations, which is almost useless. Any better ways to go about this?

My .FBX model is not picking the .TGA texture file I'm at a complete loss. An artist has sent me a 3D model so I can test it in Unity. This is exactly what I got Guy.fbx Guy DIF 512.tga Alright. So I move the folder into the Unity inspector. Suddenly, a Materials folder is created within such folder. The Materials folder has one material. Anyway, now I put the Guy prefab into the scene. It doesn't have textures applied. No problem. A simple Google search yields this response The textures for your model have to be in your Unity project for Unity to apply them automatically when you import. There are 3 different ways to make sure this happens 1 Use Textures for your 3D model from a textures directory already in your Unity project 2 Embed them in the FBX 3 Copy the textures into your project before you import your model I will avoid the second option for now to avoid troubling the artist. Let's see the third option... 3 If you are using 3D software packages that might not have newer FBX plugins or are importing native files you generally do not have the option to embed media, so you will need to copy the textures into a directory inside your project called textures nested next to the model before you import it e.g. Projectx Assets Models Textures ModelTexture.tga Projectx Assets Models Model.fbx Ok, so I created Assets Models Textures and imported the Guy DIF 512.tga file into it. Then in Assets Models folder I import the Guy.fbx file. Doesn't work. The model still doesn't have textures applied. Alright, so let's look at the first option then. ... Let's look at the first option... 1 If you create your textures in your Unity project to start with and source them from a textures directory nested under Models for example, Unity should always create materials and pick up the textures correctly at import Assets Models Textures Assets Models Uh, isn't this the same as the third option? How do I import my 3D model? I am using Unity 5.

Unity2D Horizontal Scaling to Support Various Aspect Ratios? I am trying to work out how to support various resolutions for my Android game. I have come up with a solution, but do not know how to implement it. Automatically, I am told that Unity vertically scales the screen to match the screen, leaving more room at the sides. How can I change this behaviour? I am hoping to shrunk the game down till it fits horizontally, and filling it the background above and below with more decorative features. How can I achieve this? I'm sorry if there is an obvious answer, I'm quite new working with the Unity UI system. If it makes it any easier, my game is heavily based on UI, and is locked in landscape. BIG EDIT I completely rephrased this question because it was so broad and messy.

How to sample from six cubemap images for a skybox in Shader Graph? I'm trying to update a skybox shader to URP and reimplement it in Shader Graph. The shader code itself is pretty straightforward, but I don't know enough about Shader Graph yet to set up the basic skybox. It's a standard cubemap skybox made up of six textures for x, x, y, y, z, and z. Trying to Google different variants of "unity shader graph cubemap skybox" turns up tons of noise and nothing actually useful that I can see. Does anyone know what the basic node setup is I would need to input six images and output a skybox?
