0 | How to approach a coloring app? I want to make a coloring app in unity. I don't need flood filling. THe player will select a color and click the shape to fill that color. The app will have designs as shown below Here the problem is, design has to be empty with black outline. One way would be to create textures using the jpg of each shape. However, there are thousands of shapes and each can be colored in about 7 colors. So, i will have to create 7 textures for each shape.Is there any way to create model with black outline so that only inner color can be changed? |

0 | How to serialize animation state? In Unity, I have an Animator on a character. Upon saving loading the game, I want to preserve the pose and animation state the character is in.

0 | Depth write and depth test in Unity Scenario several objects (o1, o2,.., on) have to be rendered with the z test disable, but the z values must be written to the depth buffer. In another pass, some other objects (t1, t2,..., tm) need to be rendered considering with the z test enabled, and considering the prior values from the previous pass. Is it possible to achieve this with Unity's material script? The goal is to support a custom order for the rendering of transparent objects (the o1,..,on in the scenario description) alongside with matte objects (t1,..., tm). I tried using the features mentioned here, but the results were incorrect, i.e. as if the z values were completely discarded inbetween passes. Can anyone, perhaps, share a code stub for this scenario? |
0 | Object made of cubes looks different based on the distance in Unity3D? I made a "Wall" from basic Unity3D cubes. They are placed tightly so the wall looks like one big rectangular prism. If I look at it from close distance, it looks as it should be one big rectangular prism. But if I start moving backwards, away from the wall, the cubes' edges become visible And this whole thing happens in a circular way. If I just start moving backwards from the wall, first I start to see the cubes' edges just at the further parts of the object, and then the pure white circle starts shrinking, the edges become visible at bigger and bigger parts of the object. then the blurrier edges appear at the further places and the previously appeared sharper edges circle starts shrinking as well. (this phase is shown on the image above) This should be some kind of shading optimization, like mipmap, right? How can I fix this? I want the wall to be seamless from all distances. Update Changing the shader to Unlit gt Color, fixes the issue. This thing only occurs on the lit side of the wall. The shadowy side of the wall, (which isn't lit directly by the directional light of the scene) is rendered normally. |
0 | How to "place" object in a 3d world without overlapping them ? I would like to place object in a 3d world "like minecraft player can do". What I'm trying to do is to allow the user to place objects, without overlapping them (like in minecraft you can do). So if the player try to place an object partially over another, my game automatically "move and place" the object in the allowed position. What can be the right approach ? |
0 | How do I account for the velocity difference between a ship and it's fired projectile? In my project, I have a ship that moves and increases it's movement speed with respect to time and how long the acceleration button is being pushed(just like the way a real life car works), now as expected, the ship fires projectiles when I press the fire button. The problem here, is that at a point in the game, the ship reaches it's highest speed terminal velocity, and now it's faster than the projectile it fired which is not what I want, so, how do I create a realistic projectile movement based on the ship's velocity? This is so that if the projectile is fired when the ship is moving slowly through the game scene, it doesn't move so fast that we can't see it travelling in the forward direction, and at the same time if it is fired when the ship is moving at top speeds, the ship is not seen to be faster than or as fast as the projectile's speed. I want to keep the code as optimized as possible, so I am using this line for the projectile's movement public float velocity 100f void Update() transform.position transform.forward Time.deltaTime velocity |
0 | Moving script not working after SetActive Pause change I have a pause menu for my game which instantiates a texture and sets a text frame to active and slides both objects onto the screen using the code below Instantiating the menu texture and activating the text frame public void MenuPressed () Vector3 newPosition new Vector3 ( 13, 0.06f, 2) Quaternion newRotation Quaternion.Euler (0, 0, 0) Instantiate (menu, newPosition, newRotation) menuButton.SetActive (false) textFrame.SetActive (true) Time.timeScale 0 Moving the menu items float xLimit 5 float speed 0.6f void Start () StartCoroutine ("MoveMenu") IEnumerator MoveMenu () while (true) transform.position Vector3.right speed if (gameObject.name "Main Text Frame") xLimit 7 if (transform.position.x gt xLimit) yield break yield return new WaitForEndOfFrame () Now this all works fine, but the issue that I have is on a multiple pause situation. When the pause button is pressed and spawns the menu and activates the text, the game pauses as expected. One of the options on the menu is to resume playing, when the pressed the game carries on as expected. The problem I am having is that if the pause button is pressed again, the menu texture spawns in and slides on screen as intended, but the frame for the text does not. The frame gets set active but does not actually move. Any ideas for how to fix this? P.S Here is the code I use to resume the game after it had been paused public void Button1Pressed () Time.timeScale 1 GameObject menu GameObject.FindWithTag ("Menu") Destroy (menu) gameController.paused false textFrame.SetActive (false) menuButton.SetActive (true) textFrame.transform.position new Vector3 ( 15.2f, 4.0f, 2.5f) |

0 | Correct way to project a texture with alpha and colors onto surfaces in Unity I am experimenting with Unity and wanted to project a unit circle beneath a unit and my very first naive approach was to create a child plane below the unit, assign the material to it and stretch it using the Pro Builder UV editor but it looked horrible In order to figure out what's wrong I read a lot of various approaches to "fix" that issue which were mostly the following use a higher resolution for the texture do not use any compression do not use a POT resolution change the filtering option from bilinear to point ... Eventually I figured that I have to do something completely different and that is how I stumbled upon the idea to use a shader attached to a projector game object in order to project a material. Unfortunately though it turns out the shader expects a grayscale image and only tints the projection based on a parameter. For reference this is the shader I have just copied from the web (source) 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 With that shader I was able to render the following effect Since I have no experience with shaders at all I just blatantly copy amp pasted it and do not know (yet) how to customize them or even write custom ones in the first place. Assuming my approach to combine a projector with such a shader is the way to go, I'd like to know whether there is any shader you can share that allows me to project an unlit texture with transparency and its own color such as the following example |

0 | How can I optimize coroutines? I have a script which has a Queue datastructure (code below). This queue holds more than 100 Actions. So currently my script does a yield return null after every Dequeue, which means that one Dequeue() call is executed every frame. private static readonly Queue lt Action gt DataQueue new Queue lt Action gt () private bool isHandlingQueue Helper bool to check if Coroutine is active private IEnumerator HandleQueue() isHandlingQueue true while (DataQueue.Count gt 0) DataQueue.Dequeue().Invoke() yield return null isHandlingQueue false yield return null I'm trying to achieve that multiple Dequeue and Invoke actions take place in the same frame. One Dequeue and Invoke takes between x and y ms, this varies depending on the Action itself. Example Lets say the Queue has 100 entries and the game runs at 60 frames per second (minimum). One iteration (Dequeue Invoke) in the while loop takes about 5 ms in this example. Here is the thing In this case it is essentially waiting for 11.67 ms for the next frame (16.67 ms each frame at 60fps). I don't want the system to wait, but use the remaining 11.67 ms to Dequeue and Invoke 2 more Actions, so it only waits for 1.67ms each frame. In this ideal case the Queue get's cleared in 34 frames instead of 100 frames. All help to point me in the right direction is appreciated! |

0 | Generating Mesh using Compute Shaders I am working on a game project in unity which has a procedurally generated terrain made up of 16 128 16 chunks of blocks. The map size is going to be finite (Possibly up to 100 100 chunks). Currently the data for the chunk is stored in a 1D Array, and takes a couple milliseconds to generate. But generating the mesh takes longer, averaging 30 40ms. So generating terrain as it enters the range of the camera isn't feasible as it's too slow, and generating all the meshes on load up would take a lot of memory as well as a long time. I've thought about attempting to try it on the GPU through Compute Shaders (although I don't have any experience with them). Would generating the mesh for each chunk in a Compute Shader be viable efficient? (The chunks could be made smaller if would be more performant) |

0 | How to access specific child indices (directly, not using tags or searches)? I have a game object whose prefab is structured a very specific way. It is a conveyor belt. I intend to arrange them end to end and animate them all at once using a script. Right now I am trying to get the normalized heading vector between two children, TargetStart and TargetEnd (see images below) You can see that both of these objects are children of the prefab's first child. Because all of these instances will be structured the same, I want to compute the heading for the conveyor belt by accessing the locations of these children by their indices relative to the parent (which sounds like it should be simple and should be more efficient than searching by name or tag). I am anticipating a structure like this (pseudo code) heading targetEnd's position targetStart's position vector3 heading gameObject.GetChild 0 1 .position gameObject.GetChild 0 0 .position vector3 direction heading heading.magnitude How can this be done? I would like to know this so I can access any child I need to for any object by the child's index. |

0 | How to get consecutive voice clips to sound natural In the game I'm working on I have to play several short consecutive voice clips to form a complete sentence. Example (each bracket is a different voice clip) Bob here, we're at some town and are on our way to some city . Stitching together different voice clips like this makes it sound stilted and disconnected. This is because there are unnatural pauses when switching clips, and the pitch and tone of the speaker changes. My current efforts include two methods for removing the unnatural pauses starting the next clip early if a silence is detected at the end of the preceding clip skipping the first few milliseconds of the new clip up to the first detected 'sound'. These work OK at removing the unnatural pausimh, but detecting what 'silence' is is difficult, especially when dealing with multiple voice actors and microphones. How could I make stitching together voice clips sound more natural? Any advice would be appreciated. This has to be done in real time inside the game (I'm using Unity), and can't be pre processed or done ahead of time. |

So for the GUI.Buttons (Unity4.5) to stick on their place I used a variable drawX drawX Camera.main.transform.position.x 100 The 100 is for calculating it to pixels. I then add this to my buttons when drawing. scaleX Screen.width 1920f scaleY Screen.height 1200f if (GUI.Button(new Rect((500 drawX) scaleX, 700 scaleY, 325 scaleX, 425 scaleY), "")) Now the problem is that under 1920x1200 my target resolution everything works exactly pixel perfect. But when changing the resolution or aspect ratio to something else the drawX increases to much or not enough so the buttons don't move on the same pace as they did in the 1920x1200 version. Somebody got the solution for me? |
0 | 360 Orbital Camera Controller I have a stationary cube in my scene that I'm orbiting a camera around. I have my MainCamera nested under a GameObject that I'm calling 'OrbitalCamera'. I setup the script so that a click (or tap) and drag will rotate the camera around the object in space so it feels like you're rotating the cube (ie if I click the top of a face on the cube, and pull down, I'm rotating the X value) but you'll actually be rotating the camera. For the most part, my script works. However, after rotating the Y so much, the camera is upside down and the X gets inverted. Here's my script public class OrbitalCamera MonoBehaviour public bool cameraEnabled SerializeField private float touchSensitivity SerializeField private float scrollSensitivity SerializeField private float orbitDampening protected Transform xFormCamera protected Transform xFormParent protected Vector3 localRotation protected float cameraDistance void Start () cameraEnabled true xFormCamera transform xFormParent transform.parent cameraDistance transform.position.z 1 void LateUpdate () if (cameraEnabled) TODO FIX PROBLEM WHERE WHEN CAMERA IS ROTATED TO BE UPSIDEDOWN, CONTROLS GET INVERSED if (Input.GetMouseButton(0)) if (Input.GetAxis("Mouse X") ! 0 Input.GetAxis("Mouse Y") ! 0) localRotation.x Input.GetAxis("Mouse X") touchSensitivity localRotation.y Input.GetAxis("Mouse Y") touchSensitivity Quaternion qt Quaternion.Euler(localRotation.y, localRotation.x, 0) xFormParent.rotation Quaternion.Lerp(xFormParent.rotation, qt, Time.deltaTime orbitDampening) Is there a good method to achieve this type of 360 camera? I'd like dragging from right to left to always move the camera left and dragging left to right to always move the camera right no matter how the camera is oriented. |
0 | Unity Hub 2.3.0 Buggy Setup? I recently downloaded the new Unity Hub 2.3.0 setup and since I hadn't used (or downloaded Unity Core) using the previous version of the Hub, I simply deleted the folder containing Unity Hub instead of uninstalling it like any normal person would. Now, every time I open the Unity Hub Setup and try and install it, it always shows the same "Installation Aborted, could not install successfully," error. I can't even uninstall the previous version from Windows Settings! I've tried changing the destination folder, but still doesn't work. Any help is appreciated! P.S. This error occurs when installing UnityHub, not the Unity Core Platform! I've also looked at all other similar posts. Thanks. |

0 | Projecting grid textures to select parts of the terrain (Unity) So I'm trying to be smart and not use 500 some tile prefabs to make a grid, and so far the back end portion has gone swimmingly. I initially used a dedicated mesh to represent the grid, but as I'm now opting for 3D terrain (and not tilemapping), I figured that was a lot of unnecessary vertices especially if I want to have the grid conform to the terrain. My shader inexperience, on the other hand, is causing me to stop and overthink this. Using FE as inspiration, I'm thinking about projecting the transparent grid texture onto a base terrain layer. If I wanted parts of the terrain to not be covered by the grid (such as the water area in the picture), would I simply use the world coordinates to tell the shader don't do anything there? The most confusing part for me, however, is how to go about highlighting tiles. I want movement and attack tiles to also be 'painted' onto the terrain in specific colors, but obviously they only affect an even smaller portion than the terrain than the grid. Would I simply be using the same shader to grab world coordinates once again and more or less start stop overlaying the movement attack texture over the grid terrain? And if I'm really being efficient, those textures belong to the same png and I just use UV's to switch between them like a sprite sheet? Is this even a good practice for shaders in the first place? Redrawing and adding textures to only parts of a material? Should I be redrawing and updating the whole texture instead? I guess I get thrown off because I'm only familiar with a 1 1 mesh to material design, so the so the thought of a single mesh but multiple textures on discrete parts that may or may not overlap makes somewhat sense on paper but implementation in Unity is just above me atm. Thanks! |
0 | Can't refer mesh size after using .BakeMesh() in Unity I can't figure out how to refer to the size of a particular mesh. The mesh is created through .BakeMesh(), then a box collider is added. Unfortunately the box collider has a scale of 1 by 1 by 1, regardless of how big the mesh I'm adding it to seems to be. This doesn't match my understanding of how creating a box collider should work, so I've set up a Debug.Log that outputs the mesh size. Here the plot thickens. The mesh's size just comes back at 0, 0, 0. My attempts at getting the size of the object are as follows objectToMeasure.GetComponent lt Renderer gt ().bounds.size objectToMeasure.GetComponent lt MeshFilter gt ().mesh.bounds.size objectToMeasure.GetComponent lt MeshFilter gt ().sharedMesh.bounds.size Assuming I'm referring to the size of the object in the correct way, this seems like it must be an issue created by baking the object. Do I need to wait a frame (via starting a coroutine) before trying to access the size of the object, or am I referring to the wrong component of the object, or is the BoxCollider setting it's size based on objectToMeasure's scale rather than it's size in the world? I feel sure that objectToMeasure.GetComponent().mesh.bounds.size should be right, since the script I use to bake to the mesh is meshToBake.BakeMesh(meshToMeasure.GetComponent().sharedMesh) I've been driving myself to the edge of sanity for 24 hours with this script not working, so advice is greatly appreciated. |
0 | How can I grab the script component of a collided object without knowing what script it is? CalculateDamage() is an animation event called at a point during the character's animation in my 2D game.

0 | How do I determine distance of a point within a ProBuilder mesh? As in the title, I have an effect prepped for my game which applies certain derived parameters to a post processing effect after the player enters a boundary I created with ProBuilder. Finding how far inside the bound the player is that is, how far the player would have to travel, at minimum, to leave it would help me scale this effect. It is not an axis aligned boundary, and its sloped shape is fairly important. Having the effect go full on on crossing the boundary would be jarring to the player. I'm tempted to resort to traditional edge testing with this, but I would like to highlight that it will be done at least once per frame on multiple objects, so I would like to keep it as simple, and non home rolled, as possible. The other possibility would be to keep track of time exposed and scale it by that but this isn't ideal and I'm seriously curious as to whether a penetration depth testing method exists out of box. A requested image of my setup It is laterally symmetric, and that is unlikely to ever need to change. However, future volumes are likely to have varying angles and heights. Depth is more or less irrelevant, as while I'm using 3D, this game has the physics of a 2D platformer so you can consider it to have infinite depth if you need to. As you can see on the right, I've added almost nothing to it, other than the MagneticField.cs custom script (which does not even reference the mesh, only whether it's been crossed) and a debug class, TriangleReport.cs, that I'm working on right now. One thought I had was to get triangles for the top, bottom, left, and right edges, use them to define planes, and then determine the distance from those planes but if you've got something better I am all ears! |

0 | Duplicate a Prefab as a separate asset in Unity 5.2 I have a Asset which is a collectable object Pickup and I currently have eight in my scene, I'd like to duplicate this asset and use it to harm the player Bad Pickup .

0 | How to make player stay on a moving object I've made an obstacle course with various moving parts to test out movement of a player. In the obstacle course there is a section where there are multiple cubes moves from side to side, and you have to jump from one to the other. But regardless of their speed, I can't seem to get the player to stay on top of any of the moving cubes. I have no clue how to fix this my only guess would be to use materials, but I can't apply any to the character controller. I appreciate any suggestion that you can give. Also the movement is done as an animation that I created in unity in the animation window. Thanks, Nova |
0 | How to efficiently keep the player from moving outside the gameobject he is colliding with? I am developing a game with Unity 2017. The game mechanics are as follow Classic top down RPG Movements are UP, DOWN, LEFT and RIGHT Player evolves in a 16 16 map He can dig in the direction he wants to make his way through the map one tile at a time At first I was using a very classical approach using tilemaps, RigidBody2D and BoxCollider2D on tiles and the player GameObjects. Collision detections went fine and my tilemap looked pretty much like that (red being the walls and white the empty spaces) The problem with this approach is that I have to keep in memory the state of 256 tiles in a List lt Vector2f gt and to create the 256 expected GameObjects representing either my walls (which a totally black), or my floor (the empty space). Creating a black GameObject with its own BoxCollider2D for each of the tile seems a little bit overkill. And this brings me to the second iteration of my game to keep in memory only the tiles the player digged. What I would like to achieve efficiently, is to let the player evolve as long as he is colliding with an underlying tile, but stop moving as soon as he doesn't. This is ok This isn't, and player should be placed to previous state. I could take advantage of OnTriggerEnter2d and handle custom collision and response, but I have the feeling that something more simple and more optimized may exists somehwhere in the wild! Thanks to any help provided! |
0 | Path solving for a game with a similiar pathing mechanic to Anno I cant quite wrap my head around how to solve pathing in my game. The basic premise is you will place buildings and roads on a 2d field and then you will be able to create routes from one building to another where the pathing alghorithm should figure out the shortest path between them (if there is one). Something to keep in mind is that the game is going to be quazi infinite scale (think factorio) and i cant think of a performant enough solution. Currently what i am working with is that i have every straight Path segment saved as two (startPoint, endPoint) Vector2Int points in a list. And everytime a new road gets added or some road segment deleted i update this list depending on what happened, example situation I have this road This would be represented in my Roads list as 0 startPoint(0, 0) gt endPoint(5, 0) 1 startPoint(5, 0) gt endPoint(5, 3) 2 startPoint(5, 3) gt endPoint(10, 3) I now add another road so we have something like this Which would change the road list to something like 0 startPoint(0, 0) gt endPoint(5, 0) 1 startPoint(5, 0) gt endPoint(5, 2) 2 startPoint(5, 2) gt endPoint(5, 3) 3 startPoint(1, 2) gt endPoint(5, 2) 4 startPoint(5, 3) gt endPoint(10, 3) What i am doing currently when a new route is to be calculated is that i create a 2d bool array which i am feeding into a A solver to get the shortest path so the above road gets transformed into 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 With some starting and endpoint. This works fine for now but when the player will build on a huge size 10kx10k, i cant imagine generating 10kx10k bool array everytime will be a good solution. Anybody knows how to optimize this? |
0 | How to figure out what's moving my GameObject? I have a GameObject as part of a complex scene with a handful of interconnected parts, that's moving when it shouldn't be. I've tried running under the debugger and setting breakpoints on all of the script points that are supposed to move its Transform, and ensured that none of them are firing. There seems to be some "spooky action at a distance" going on, some rogue script doing something I don't want it to be doing, but I can't for the life of me figure out where it is. What I'd really like is some way to set a "breakpoint" on the object's Transform that will break me into the debugger when it gets moved by any script, but that doesn't appear to be supported. Is there any way to figure out exactly what it is that's moving my object around when it shouldn't be? (And before anyone says "trial and error, disable components and see when it stops moving," I already know exactly which component to disable to make it stop moving. Unfortunately, that isn't helping track down the problem because the movement isn't coming directly from that component's MonoBehaviour script.) |
0 | Step by step 3D Game Design in Unity My main question is related to 3D game design for Unity, but please let me introduce my idea so that you can understand what I really mean. I am very eager to develop an adventurous travel 3D game (Unity), where the main character is given some kind of task in country A and if he deals with it, he goes to the upper level, which is in another country and so on. I have never developed a computer game before. I have knowledge of c and a bit of java (for the programming part of the game). But I really don t know where to start with the design. I have to think of a main character, episodic characters, environment and distinctive buildings for each country in 3D (for e.g. The Eiffel Tower in Paris, The Colloseum in Rome, The Great wall of China etc. ). My question is where to begin with the 3D design of the characters, the cities and the buildings? Can you please give me step by step instructions so that I can do something good and meaningful? I know that Blender is a good option for 3D modeling, but is it the only thing needed for the 3D game design? I have experience with Adobe Illustrator, so can I use it to some extent in this case (for 3D game elements)? Can I use Illustrator then import it in Blender and finally import the Blender product in Unity? I accept every advice given. I really need someone to explain these things to me because for now I am really puzzled and not orientated from where to begin. Thank you! |

0 | Profiling unity games on Android devices I would like to profile our Unity mobile game on Android devices in a way similar to profiling Unity games on iOS with Instruments. I am aware of how to do this using Unity's profiler, I would however like to use a third party profiler for the following reasons to validate Unity's profiling data to have more visibility into how the app is running, including Unity's functions, etc. the largest lag spikes cause unity's profiler to run out of samples. I'm however very interested in precisely these spikes I'd like to have profile data for longer periods than unity records for I'd like to do analysis over time (not just detailed data for each frame, but also aggregated over a time span) Essentially I'd like as much visibility as possible to make Android on device profiling as comprehensive as possible. As close to Instruments on iOS as possible. So far I've tried with DDMS, but could only get visibility into Andoid OS functions and seeminly nothing in the actual apk at least nothing I recognised. I tried with mono2x and il2cpp, with all debug features that I'm aware of in build and player settings enabled. The game is developed with Unity 5,4 with Mono2x. All help is appreciated. I've listed my intents above, so even if profiling on device is not possible in this way on Andoid, alternate solutions to the listed intents are still very appreciated. Thanks! |

0 | Export Spriter animations to Unity I want to use bone animations in my 2D game for Unity (5.0 beta). I am trying Spriter. Apparently, it has no official Unity support. There was some guy, back in 2014, who posted a plugin to convert Spriter files to Unity prefabs here http brashmonkey.com forum index.php? topic 3365 spriter for unity 43 updated integrated . However, the plugin does not seem to work (perhaps it is because I am using 5.0 beta). There are deprecated lines, like AnimationUtility.SetAnimationType(animClip, ModelImporterAnimationType.Generic) Or UnityEditor.Animations.AnimatorController.AddAnimationClipToController(controller, animationClip) If you remove them, of course it won't be able to properly export your files. So my question is is there a reasonable to use Spriter animations in Unity? I know I could just export to a spritesheet, but I was hoping to use bones for super fluid animations (I have several characters so I don't really want to make lots of spritesheets). Or perhaps there is a better bone based solution for 2D animation in Unity? |

0 | Unity3d iOS build where are the textures? First time building and running my Unity3D app on my iPhone and it appears that all the textures are missing. Everything is just a solid block of whatever color I made it. When running in Unity I see everything correctly. See images below. To complicate things I'm using custom shaders, and all the objects are custom procedural meshes. Quads that I build in script. If I switch the paper backplate shader to a built in shader I still only see white on the iPhone. So I suspect that somehow the textures just aren't making it to the iOS project. When I look in the iOS project I can't find any textures. Where would they be in the iOS project? For example in Xcode under Build Phases Copy Bundle Resources the only thing there is the Images.xcassets, which only contains the splash screens and icons. Surely I'm missing something simple. I tried renaming the folder where I keep my textures to "Textures". Also my textures are not built in to the shader but added programmatically like this void Awake () meshFilterComponent GetComponent lt MeshFilter gt () Material material GetComponent lt MeshRenderer gt ().material material.SetTexture(0, paperTexture) material.color new Vector4(1f, 1f, 1f, 1f) Where paperTexture is set up in the GameObject to point to the correct texture. Is there any way to force a texture to be part of a build? Let's say that you swap out textures in code, like swapping themes, how would you make sure they're all there to be loaded as needed?

0 | Unity Rendering Pass Before Refraction not showing In the documentation it states Before Refraction Draws the GameObject before the refraction pass. This means that HDRP includes this Material when it processes refraction. To expose this option, select Transparent from the Surface Type drop down.

Are there some other option that might be disabling it? |

0 | How to develop custom Unity graphics? Processing is a Java library for working with computer graphics, providing methods by which to draw primitive objects, custom meshes, etc., as well as mathematical methods (such as Simple Harmonic Motion) by which to animate and control them. p5.js is an equivalent library for JavaScript and working with graphics on the web. You also have openFramworks which is similar but for C . How can you achieve similar graphics capabilities in the Unity Game Engine? Suppose, for example, I wanted to build a game like Duet. I can imagine how I might go about creating those graphics in Processing or p5.js, but not in Unity and C . How can you have that kind of creative freedom to build and draw in Unity? Thanks. |
0 | How to create a puzzle where the player needs to rotate hexagons to connect to the neighbors? I was researching different puzzle ideas and came across a game called Warframe that requires the player to hack a console to progress further into the level. The player has to spin around the hexagons (randomly generated, and get more difficult later on) to link up the connections to other hexagon neighbors. It's simple for the player to do, but also quite fun from my research. How can I create something similar to this? Edit To be more specific I would like to know how to generate a puzzle like below and how to check for successful connections. The graphics, animations, and player input I can handle. I suppose it's more about the algorithms to create the puzzle and then check the conditions. I couldn't figure out good search terms to find something similar. So even if someone can point me in the right direction, that would be helpful. I will be doing this in Unity C . Example of doing a puzzle. |
0 | Does it make sense to export and use skeletal animation as sprites? As tools like Dragonbones, Spine lets you export animations as both sprite atlas and skeleton data (JSON binary), I'm not sure which format to use when importing to Unity. I have few concerns Will there be any differences between the quality of the animations, when imported as atlas vs skeleton data? Any other pros and cons, using one over the other? If I use a sprite atlas, I don't have to depend on a third party runtime though. It is for mobile, so performance is also a concern. |
0 | Unity Deactivating Keyboard Input Interpolation I'm working on a game in Unity, and it is a little jarring to use with keyboard controls. I'm using the built in Input Manager, where I have a set of axes mapped to the left and right keys. When the player is using the keyboard instead of a joystick, I'd like it to simply be 1 when hitting left, 1 when hitting right, and 0 otherwise, but this isn't the case. I've found that for the first few frames of the button being held, Unity automatically builds up to the value for example, if I'm holding right, the value wouldn't go straight from 0 to 1, but rather from 0, to 0.25, to 0.5 and so on, continuously up to 1. Can I deactivate this? If so, how? Thanks in advance. |
0 | Manipulating an animation towards a target object (ie.

I will give the punch a set amount which it can move from the standard animation and move the hand bone in the direction of the targets head object. But I don't know how to do this S So far i have used dragged the 3 animation files into Mecanim and coded it to do the animations when a button is pressed. Is there a way to manipulate the animation in this way? (ie. actually make the arm reach towards the target object ) |

0 | Keeping a Character Controller grounded? I've got a character that makes use of isGrounded() to determine whether I can jump, whether my air jump is reset, and the amount of friction to be applied. I've run into a common problem, isGrounded() is fluctuating every frame returning true and false randomly resulting in jagged movement. The standard suggestion is to constantly apply gravity. Unfortunately, aside from any other more nuanced issues that this could result in, this only works for me if I apply so much gravity that I am no longer able to climb up slopes. I need a way to keep the character grounded without applying large amounts of gravity every frame. |
0 | Agents going to the same position So more often than not I have a case where two agents get the same destination vector3.

0 | SpriteRenderer batching issue, with Z Position and Order in Layer I have two sprites (they look the same but with different colors) I want them to be positioned like on the image above, so there's a feel like blue is standing on the green one.

0 | 2D active ragdoll physics based procedural animation I'm trying to make a 2D quadraped robot stand and walk via physics. My robot looks like this. (art is not mine. Source is vapgames) It's rigged via Unity's 2D animation package and each joint bone has it's own collider rigidbody with the legs also having hingejoints connecting the lower part to the upper part and the upper part to the main body of the robot. I've also set up IK for both legs using the 2D IK package with the IK target being attached to their respective leg via fixedjoint and can be moved programmatically to move the legs with respect to IK. I want it to stand up, as at the moment is just falls and acts as a generic limp ragdoll. I've tried these methods Adding downward force to the legs via the IK targets Adding upward force to the torso Animating the IK targets to try and get the bot to stand up with animatePhysics enabled. All of these failed (downard force to legs did pretty much nothing, upward force to torso just made it float if there was no ground, animating the IK targets was too glitchy). I'm out of ideas on how to actually do this now. I've looked around for guides but there seems to be nothing good (I keep getting this suggested to me but it doesn't help. It's in 3D and the only thing that could help, spider legs, isn't finished and probably never will be) There's very little information on how to do this sort of stuff and even when I find people who know about active ragdolls they just say add force to the head (for a 3D active ragdoll), which I've already tried (see 2. on the list of what I've already tried) and don't explain anyt further. If anyone could help, that'd be great! |

0 | Component based programming with child objects I am presently working on a game in Unity3d and have come to a cross road regarding scripting for repetitive child objects. Should these child objects handle its own scripting for best practice? For example, I have a parent game object, Game Board, that spawns repetitive child objects, Tiles, on the board. Right now, I let these child objects handle its own position on the board and its own animation when the tiles move. However, I can just as easily do this with the parent object's scripting class. The reason I chose to let the child object do so is because I believe that child objects should be as independent to the parent object as much as possible. But since these are repetitive child objects, I start to wonder if it is just as easy to do all the scripting in the parent object. This way I decrease the number of class instances in the child objects. According the component based programming, which method is recommended? |
0 | Seams between tiled textured cubes I've created a textured cube in Blender, which I have uv mapped like this The tiles are 256x256, and I've mapped the coordinates exactly at the edges (e.g. x 256, y 512). I then export my model as an fbx file to Unity. In Unity, if I put many cubes adjacent to each other, seams appear between the cubes, like this I think I understand why this happens, because the uv coordinates are exactly on the edges, and thus two faces sample from the same points along an edge. I could solve this in some ways By making the uv tiles smaller, but it would look ugly with patterns. By adding some space between the tiles in the texture, and aligning the uv coordinates to them. My question is there a better proper way for achieving this? UPDATE So, about half a year later I still have issues with the seams. I've tried many things Start uv coordinates at 256.5 instead of 256, and so on... Turned of mipmapping. Set wrap mode to clamp. Set filter mode to point filter. Edge padded the texture atlas with first 4px, 8px, 16px, 32px. But still bleeding occurs at certain angles. Also updated the uv coordinates accordingly. Changed my atlas to be of Power of 2 instead, i.e. 1024x1024 instead of 1024x768. Set quot Non Power of 2 quot in Unity to None so Unity doesn't rescale my texture to nearest Power of 2. Set texture format to Automatic Truecolor instead of Compressed. With 32px edge padding it actually gets a lot better, but it still isn't perfect, I guess I could go on and try even more padding, but my textures will get bigger and bigger. I understand now that it is the mip levels that are causing the bleeding. At far distances I don't think this is a problem, but I can see this occuring just about 5 7 units away from the player, if the player is looking down. I believe there is something trivial about this that I'm missing. This is really a showstopper for me, forever grateful to the one who helps me solve this. Thanks in advance! This is how I have edge padded my texture (lines not visible on real texture), the problem does not only occur when the faces has such extremes distinct difference in colors as this one. It also occurs when the faces have patterns. |
0 | Unity I need to edit my prefab but I can't move anything inside it! I imported a character into Unity and turned him into a prefab. I couldn't get my custom "Look At" script to work for the eyes, which are children of the prefab I imported. So I opened the prefab and discovered (to my HORROR) that I am unable to transform his eyes AT ALL, even in the prefab view. It's like his body parts are made of stone, or something! I checked his eyes in the Blender scene and don't see any animation data attached to them. So how could this happen? How can I fix it? The eyes ARE children of a bone called "root", which I don't think has any keyframes in any animation. Further, all my bones imported as empties. |

0 | Unity Lerping Following Camera is too slow I'm using this script to follow a game object in 2D public class CameraFollow MonoBehaviour ... void LateUpdate() Vector3 position target transform.position float targetX position.x float targetY position.y targetX Mathf.Lerp(transform.position.x, targetX, 1 m DampTime Time.deltaTime) targetY Mathf.Lerp(transform.position.y, targetY, m DampTime Time.deltaTime) transform.position new Vector3(targetX, targetY, initial z) I've set damping time to 2. But with this when the object's speed gets higher it can't follow anymore, it lags. Any suggestions or solutions ? Here is the current situation |
