0 | strategies for detecting regressions I know writing tests would be a good way to catch regressions. But what are some other strategies? TDD and game dev don't suit, but catching regressions is obviously something desirable. I would love to find some cheap and easier ways to catch regressions without having to invest a lot of effort or writing tests after the fact. Strategies suggested don't have to be perfect, if they can give rough ideas or things to playtest rapidly then that would also be beneficial. Please advise. |
0 | Black and white textures load as turquoise? I have some black and white, and some grayscale textures, that are loading in unity as turquoise and white textures. What is causing this and how can I fix this? Also, can somebody verify that I am supposed to load roughness textures into the "Metallic" slot of the Standard shader? That feels so weird. I was using Principled Shader in Blender to make the original materials. EDIT "Autodesk Interactive" shader has a "Roughness" input but most of my roughness textures and some b amp w textures are still turquoise, what is happening... Here is one of the problem textures (the others are too big, 6mb) |
0 | Best approach for destructible car in Unity I'm developing a simple racing car game. I'm wondering what is the best approach to manage visually car destruction. For instance i think one option (expensive) is to build car 3d model with 'separate' mesh, each for any component (bump, door, glass) and relative cooliders.. Other options ? Thanks |
0 | Prefabs moved to before position when zooming scene I have build some pipes for waterline drawing, like following screencast https youtu.be WnJb1JwOW78 As you can see, when I zoom in the scene, Pipes moved to lower position. When i zoom out, Pipes moved to higher position. Actually I have changed the position and moved down the pipe position before, the unexpected higher position was the pipe before position. So i guessing this problem might about cache clean. So I I try to clear the GI cache, but the problem still exist. And then I try to build a windows executable file and run game again, problem still. How to fix it? I am using Unity 2018.4 |
0 | Roofs not appearing in Unity My buildings are fine until I import them to Unity. None of the formats I've come across( FBX, DAE, 3DS Max, Blender Files, any of the Autocad formats, OBJ, PRJ, WRL etc.), have roofs when importing the buildings as one cohesive file into Unity. In Sketchup, Blender etc. they all appear fine. Does anyone have suggestions? |

0 | How do you manage versioning across platforms in Unity? I'm just beginning to look into versioning games in Unity and noticed that Unity seems to offer different things depending on the platform you are building for. For instance, Android and iOS seem to have their own individual properties for versioning while Desktop has no versioning functionality at all out of the box. Since I'm working on a game that has builds for PC, Mac, Android, and iOS, I need to determine how we want to manage version numbers within our game without having to manually manage individual version for each platform. How do you solve this? |

What am I doing wrong? |

0 | Difference between Update method and FixedUpdate in Unity? i am starting to learn Unity3d and one of the confusion i get is difference between Update() and FixedUpdate(). I am following Lynda Unity 2D game development tutorial there, the instructor uses Update method, the player has RigidBody2D component and Box collider, he uses the Update method to translate the player, but when i do same in Update the player doesn't move but when i do it in FixedUpdate, everything works. He is giving tutorial from Unity 4.3 and i am taking the course in Unity 4.6. Where should i use Update and FixedUpdate? |

0 | Unity Input System On Screen Button doesn't work with touchscreen 2019.3.2f1 I am trying to make my player jump whenever the space button is pressed (if a keyboard is present), and I'm adding a on screen button for players on mobile. The on screen button works fine in the editor but when I try the game in a device the on screen button doesn't work. Here's how things are set up Change the Active Input Handling to Input System Package (New) on the player settings. Create the Jump action for the Player action map. Bind lt Keyboard gt space to my Jump action. Add a PlayerInput component to my player object, pass my actions file to it, and set up the events to call for each action. Change the StandaloneInputModule to an InputSystemUIInputModule in my event system object. In my canvas I add an image and add OnScreenButton component to it (I do NOT add a Button component). Set the control path to lt Keyboard gt space. When I try the game on the device the rest of the UI buttons work fine except the on screen button. On the editor though (using mouse input), the on screen button works fine. This is my first time using the Input System, I had actually found it somewhat nice to work with, however this does seem really strange. It is either a really strange bug (unlikely), or I messed up some setting (the setup process feels really convoluted actually). |

0 | How do I roll a ball with a Rigidbody? I have a ball in a game that rolls around just fine with Rigidbody.AddForce(). I have other non physics balls, however, that I control directly with Rigidbody.MovePosition(). It seems that no matter what I do, no matter how interpolation and collision detection are set, the ball does not "roll" when moved with Rigidbody.MovePosition(). It teleports, but IsKinematic is not set , as instructed by the documentation. How do I get the ball to roll properly with Rigidbody.MovePosition()? Alternatively, if that's not possible, how do I calculate the rotations manually? |
0 | Unity 3D, Making contiguous looking worlds Im currently involved in making a third person cooperative mobile game in Unity and in said game there will be an area for players to walk around in with various elevations and whatnot throughout the field. Its designed to be set up with 4 biomes in the area to go along with the games theme but I was wondering what would be the best way to mask the "boundaries" or "cut off points" in this area? From certain vantage points its pretty obvious that the terrain used to make the world simply stops and I was wondering if anyone knew any tips and insights on how to best mask these boundaries without too much "padding" in the game area in order to keep it relatively less taxing on a mobile device. Thank you in advance. |
0 | In Unity, how to hide objects from specific cameras without using Layers The situation is that there are multiple players that can collect items. When a player collects an item, the item will disappear from that player's screen but still be visible to other players. I know I can use LayerMask to achieve this effect. However, what if there are more than 32 players? (Unity Layer has 32 bits). How can I still hold this effect? I tried using OnWillRender() to check which camera is rendering the object in order to disable its renderer. This does not work because once the renderer has been disabled, OnWillRender() will not be called again for other cameras. |
0 | Unity3d CarController character positioning issue I use the unity standard asset components CharacterController and Car and put an empty gameobject onto the car where the camera should be placed when i am inside the car.

0 | Swiping with rigidbody My character moves continuously forward with rigidbody.velocity v3Force strength My Swipe script is based on a youtube tutorial from https www.youtube.com watch?v 9ZIHx09GevI I just changed the end result with rigidbody.AddForce(v2Force strength1) For Right Swipe and below for Left Swipe rigidbody.AddForce(v1Force strength1) Here are the vForce variables var v1Force Vector3 transform.right var v2Force Vector3 transform.right var v3Force Vector3 transform.forward The swipe works fine, but the result isn't what I'm aiming for because when I swipe left right my character seems to be moving only one frame left right. And then continues moving forward. When I disable the forward movement, the swipe works great and makes my character move right left for a period of time, after I swipe. My question is how do I reach this result(moving sideways more than just a frame) with my continuous forward movement enabled? |
0 | Making NavMeshAgent to look the direction it was moving when it stops I'm currently using NavMeshAgent as my player character controlled by keyboard or gamepad input.

0 | Transactions on lists of coins of different values For learning purposes, I am developing the first steps of an idle game with exponentially higher income numbers. Usual int, long, etc. can't store big enough numbers for that. I looked through many threads which I found on google and using a list (or an array) which is separated in e.g. bronze coins, silver coins, gold coins, etc. seems to be the cleanest version. In my first approaches I created this list namespace Coins public class script coinHandler MonoBehaviour public List lt Coin gt coinList new List lt Coin gt () list based on the quot Coin quot class new Coin() Name quot bronze quot , new Coin() Name quot silver quot , new Coin() Name quot gold quot , new Coin() Name quot diamond quot , public class Coin public string Name get set public int Amount get set public int Multiplier get set I want each coin type to go up to 999999. This means 1 silver 1000000 bronze, 1 gold 1000000 silver. I can't get my head around a way to do maths with this list. Example Player has 3000 GOLD, 320000 SILVER, 524321 BRONZE Player wants to buy something for 20 GOLD, 120000 SILVER, 300000 BRONZE Just subtracting 20 from GOLD, 120000 from SILVER, and 300000 from BRONZE won't always work. For example when a Player has no BRONZE but some SILVER you can't subtract 300000 BRONZE without converting SILVER to BRONZE first. Q What would be an efficient function to subtract the price from the total amount? What about multiplying and dividing? Accuracy is not important. When spending a few GOLD, nobody will care about 10000 BRONZE. |

0 | How to use rigid bodies for characters? First off, I am making a game similar to SSB, which relies heavily on physics, even though it is a sidescroller. I am currently using Unity. In Unity there are quot character controllers quot which are used for characters that move, but they don't interact with other physics objects. There are also rigid bodies, which are completely realistic physics components. I can't figure out how to use rigid bodies for human humanoid characters. Here's some questions I have How should I move the character? Applying forces is not the way to do it, right? Would you set velocities or pixel by pixel movement, perhaps? What kind of collider should I use? I've been using a capsule collider. But is that the best way? How do you make him not fall down!? After some experimenting, I discovered that the character falls over (from applying force velocity and from the capsule collider tipping it over). Would you constrain the rotation in the Z axis? What do you do when he gets hit? If you've ever played SSBB you'll be familiar with this topic. I'm thinking that applying a force would be best in this condition? If you did constrain the rotation, would you un constrain it? |
0 | Execute function every X points In my game, the score can go up quite rapidly and by varying amounts, depending on the action taken. For instance, at the start of the game, one could climb from 1 50 one by one, or they could rocket past 50 by getting a score of 10, 25, and 40. My question is How do I call a function every time they pass a factor of 50 (50, 100, 150, 200, etc.)? |

0 | Understanding Torque in Unity This is (hopefully) a simple question that should avoid me asking a more complex question. This is in Unity (2D) but hopefully this is a general physics principle I am not getting. I am applying a torque to a 2D object. The object has a scale of 1, a RigidBody2D with a mass of 1 and no angular drag or undergoing gravity. It is a CircleCollider2D with a radius of 1. There is nothing else attached to the object. In the following code I apply a torque of Pi for one second. In linear motion (and from my understanding of torque) I would expect the angular velocity, after one second, to be Pi (or 180deg s). However, running this code and printing out the speed at t 1.0, the speed is 90deg s. void FixedUpdate() if (time lt 1.0f) rigidbody2D.AddTorque(Mathf.PI) This is consistent, applying a torque of 2Pi gives me a velocity of 1Pi after the time. Where is this factor of 2 coming from? |
0 | Does transparency work with SSS in Unity's HDRP Lit shader? I am using Unity's HDRP Lit shader in Shader Graph (all are version 4.8.0 preview) on Unity 2018.3.0b12. I am trying to use both transparency and subsurface scattering on the material. However, it appears that the visual appearance loses SSS when transparency is introduced. Example The cube on the left has transparency enabled, and has no visible SSS. The cube on the right has the same SSS settings as the left cube, however the right cube has no transparency enabled. I need transparency to fade in the cube depending on its position, like this And here is my master node If anyone has an alternative solution that sidesteps this potential limitation, I am all ears. Cheers! |
0 | Unity Vector3 position inside collider I am trying to create a "wander" action that will make my NPC walk to a random position. The catch is that the NPC should only go positions inside of a collider. I have a huge Sphere that has a collider on it now I only want my NPC to go to positions that are inside that Sphere collider. My question is how do i find a random position inside of a colider? Update So after testing i am unable to use colliders because the sphere is too big here is an image of my gameobject As you can see from the image I have a huge sphere that my NPC's will have to stay inside when wandering In order to use the Collider.ClosestPoint() the collider has to be a Box, sphere or a mesh collider with a convex. Sadly this is not feasible for me because the sphere should not collide with other objects. So my question is how do I find a point inside this gameobject? |
0 | Unity blur on one camera effects the other as well I'm trying to fake a DOF effect for Sprites by using 2 cameras, one for the sharp objects, one for the blurred ones. I have set up the layers like Blur and Sharp accordingly. So I have these 2 cameras, and I use Unity's Blur (optimized) script to blur things, and I have this script on only one camera, the one that is responsible for the blurred render. I have the cameras like Cam 1 Clear flags Don't clear (this is the main, sharp cam) Culling mask sharp layer has no blur effect (or any other post proc effect). Cam 2 Clear flags don't clear (this is the blur cam) culling mask blur Has Blur (optimized). Now, if this blur cam is on the back, meaning its depth is LESS than the main cam's depth, I have a sharp player ground and a blurry background. However, I need a blurry foreground too that should be on top of the player ground. The issue starts when I set the blur camera's depth higher than the main cam's. In this case, everything gets blurred, no matter that the main cam has no blur effect on it. Question is, how to set this up so only the desired layers get the blur? |

0 | How do I prevent floating and jittering when on the ground and using spherical gravity? TL DR My ship floats and jitters when it lands on a sphere. To elaborate on the title I'm experimenting with a 3D space game. I have created a sphere, which in turn has a larger sphere overlapping it, within which, gravity will take place. However, once my player's ship (currently using an arrowhead) lands on the planet, it doesn't actually make contact with the surface of the sphere, and then the ship begins to rotate erratically and jitter. Code below. private void OnTriggerStay(Collider other) if (other.CompareTag("SoI")) inSoI true This trigger checks to see if the ship is in the larger overlapping sphere. I have another identical block for OnTriggerExit which sets inSoI to false. I also have a OnCollisionEnter which sets another variable, landed to true, and a OnCollisionExit which sets it to false. private void FixedUpdate() if (inSoI amp amp !landed) gravityVector (planet.transform.position transform.position) rb.AddForce(gravityVector.normalized planetrb.mass rb.mass gravityVector.sqrMagnitude) Simply, if in the larger sphere, then accelerate towards the planet. I tried disabling gravity if in contact with the sphere. It removed a lot of the jitter, however it still floats, and it still rotates side to side. The sphere by the way, is the standard Unity sphere, scaled 10000x in every axis. I don't need code (though it would help), any solution is fine, even if it means abandoning the project. |

0 | Game is darker on build I've been recently doing test builds of my game. In Unity, I worked on baking the lighting to ensure everything looked fine. However, upon building, the game level becomes far darker and much of the lighting and baking is ineffective. Here is how the scene looks in the editor And here is how it looks in the built game It's much darker than intended. Here are my lighting settings which I've baked in Unity's Editor. These settings and lightmap parameters were designed to, at least in the editor, provide decent quality while making light bake times relatively quick. However, I've noticed that newer Unity's Lighting settings are way different now, so perhaps something is amiss here? I've been at my wits end trying to figure this out for the past while, but I can't figure out why this is happening or how to fix it. Any ideas? |

0 | Is wireframe effect possible without geometry shader? I am trying to write a shader that highlight the edge between each pair of vertices, much like the UCLA Wireframe Shader. All implementations I came across require geometry shader support. I am wondering if this is possible with just vertex and fragment shaders?

On the other hand, I could just use geometry shader but it presents quite a problem when porting to iOS, which lacks support.) |
0 | Build includes sprite packer atlas and its original textures I use Unity's Sprite Packer, it's working great. However, when I looked at the build report (in the Editor.log) it turns out that the build often includes the generated atlas texture and its original textures too. It wastes too much space. I checked the size of the unzipped APK and the build report was correct. I tried several configurations (adding and removing textures) but I could not find any regularities. Some observations I could reproduce this only if I use 25 textures in an atlas with variable sizes. Texture compression settings did not matter. Packer policy could modify the result but did not solve the problem. Has anybody had similar experience? I can upload my test project if necessary. |

0 | Why are cube map axes sometimes labelled incorrectly? In both 3ds Max (which uses a right handed coordinate system) and Unity (which uses a left handed coordinate system), the cube map faces labelled "left" and "right" show the view facing the opposite direction. This is not the case with the front, back, up, or down directions. In 3ds Max, this is in the context of rendering cube map images from a Reflect Refract map. In Unity, both cube map textures and skyboxes exhibit the same left right "confusion". Oddly, however, the GUI labels for cube maps indicate that left is the X direction and right is the X direction which is correct in Unity while skyboxes indicate the opposite (all other axial labels are consistent between the two). The upshot of this is that cube map images rendered by 3ds Max (which each have a suffix indicating their viewing direction) can be assigned to the texture slots in Unity with the same name and everything will work, but only because both programs label the left view as "right" and vice versa. The only discussion of this I was able to find online was in a blog post on floored.com (search for "Unity Skybox Weirdness" and it should come up I'd post a link but I lack sufficient reputation to include more than two). Here's an image from the post that illustrates the issue Is there a reason why the left right axes of cube maps are mislabelled in both of these programs? Although it's trivial to ignore once you're aware of it, it seems like there should be a good (or at least historical) explanation for it, unless it's simply a case of a long overlooked bug in 3ds Max that the Unity developers decided to accommodate. Any thoughts would be appreciated! |
0 | How to disable animation root motion I downloaded some animations with root motion from Mixamo and the corresponding character model. After created an animator with those animations and added it to the character game object, the root motion was causing the transform to move around, which was not supposed to happen. I tried to uncheck "Apply Root Motion", and set "Motion Root Motion Node" to "None", but neither of them worked. The only thing that worked is checking "Loop Time Loop Pose", but it doesn't make much sense to mess with root motion, someone even proposed it shouldn't disable root motion. So, how to disable animation root motion? Also I'm confused, is root motion optional? Must I get animations without root motion if it's not needed? |

0 | How can I simulate a "Hot Swap" betwen Audio Clips? I have a Unity project with 3 separate looping Audio Clips and a single Audio Source. Based on certain events, I swap between which of them are playing. This works fine, but whenever I swap between Audio Clips, the AudioSource stops playing, and must be restarted... which means it starts over from the beginning. As the Audio Clips are the same length, how should I handle the logic to pickup where the previous Clip last left off? Neither Unity's AudioClip nor AudioSource classes seem to have either a "PlayFromTime()" or "GetPercentPlayed()" method that would facilitate using a single Audio Source. What's the expected way to handle such a scenario? Simultaneously "play" from 3 AudioSources at once, muting 2 of them and leaving the last the only one that is actually heard? |

0 | Text Pooling Optimizations In my game I have created popup text for gained points when enemies are killed. it pops up wherever the enemy was and will say something like " 32" float up a bit and fade away at the same time. This transition lasts for a few seconds if that. and hundreds could appear at a time when AoE attacks destroy a lot of enemies. That's all well and good. and it works! but I fear that this could become quite slow on mobile devices. So I did what any good game dev does. I pooled it! Then it occurred to me. I'll still be changing the display value of the text elements dynamically and libraries like TextMeshPro already, in surely an optimized way, instantiate actual meshes to render text. So is pooling these text elements really a big optimization? so here goes my question for experienced and knowledgeable devs. Is it more efficient to pool each character I need and assemble my short strings dynamically as sets of pooled gameobjects for these popups of just a few characters or should I simply pool text elements that will change their text just before appearing? Assume the memory usage difference is minimal. only worried about speed. This is on top of the game having possibly thousands of projectiles moving at any given time, so I believe it is a valid optimization question, but I ask this more for curiosity than practicality. For now, I already have a working solution. but I believe such an issue could arise in the future. and want to satisfy my curiosity now. |

How can I use pointers with the variable types in Unity (Vector3s, Transforms, GameObjects, etc...)? There are so many more questions I probably should and would like to ask so if you have any additional info or sources. |

0 | Random scene manager in Unity This may be hard to understand because this is hard to explain I have 6 scenes and one 'start' scene. The start scene will be where my scene manager is. So I want function where when the player clicks on the the start scene it goes to a random scene (from the 6 scenes) and then it goes to start. Then when you click again it goes to random scene, but this time these random scenes will be between the remaining 5 (excluding the scene the player just went on) and then it goes back to start. Then it goes to a random scene time, this time these random scene will be between the remaining 4. And so one. I already know how to go a random scene and back but I don't know how to do the remaining |
0 | How to make multiple AI surround a player I am working on a top down RPG game and I have come across a problem. I am working on an AI system to allow the enemy AI to surround the player. I've been trying to keep my implementation really simple, however, I've been running into problems. Here is what it currently looks like X represents the player and Y represents the friendly AI. There are 42 waypoints in total that the enemy can potentially occupy. However, if any of the waypoints of the player object encounters an obstacle, or if another friendly AI is too close, it will disable those waypoints This poses a big problem because I do not have all 42 waypoints. From the looks of it, I might need something more dynamic in my case. Are there any alternative ways to allow a large number of AI to surround the player or its allies? |

0 | Unity 3D Slow car (wheel colliders) My car is moving very slowly even though I apply high amounts of torque to the wheel colliders. The only thing I found to be helpful was to increase the wheel's friction stiffness, but that really messes up the braking and makes the car shake. The values I use for setting up the car and torque are realistic (1500 kg car, 20 kg wheels, a realistic torque value accounting for gear ratios etc.), so I don't understand the problem. |

0 | How to add tiles randomly? I made a set of 10 different "ocean" tiles, all interchangeable with one another, and I'd like to randomly attach these 10 different tiles together in different combinations over a large rectangular area what would be the best way to do so? I've thought of just adding each sprite into a script and then calling a for foreach loop to add it into my world but that seems extremely expensive since I'd be adding over 1000 sprites. I don't want to reduce the number of sprites I have to add, I'm just seeing if there's a typical way people do this sort of thing. |

0 | Is there any way to bring animation into unity without a rig bones? I am developing for mobile and to make the game run on lower spec mobiles, I was only going to import bones rig for the main character. There are other humanoid characters in the scene which do move about and are rigged already in my 3d app but since they wont be controlled in anyway by the player in the game, I just wanted to bake and import their animations alone without the bones. I know unity can handle blendshapes but I am more comfortable with rigs and also cos these characters are already rigged properly. |
0 | Recommended data structure for storage and fast access of infinite chunk based heightmap terrain I'm aiming to create a chunk based heightmap terrain in Unity. I already have a basic multifractal simplex noise set up and working, able to generate heightfields and meshes at runtime... but only individually for the moment. I'm attempting to work out how best to store and access each chunk. I already have a couple of methods worked out to convert global positions to chunk coordinates and chunk local barycentric triangle coordinates, so I can interpolate heights. I've used that to build a method to march a camera space to world space ray across the mesh and iterate through x z plane intersections until it finds the height intersection for a fast way to look up mouse position on the terrain without having to attach physics collision meshes for each chunk and use Unity's raycasting. That's all working nicely. I'm just a bit stumped now on how to implement the main infinite grid storage that I'll generate chunk meshes from. This is planned to be in service of a game with an isometric perspective, revealing the world as units explore fog of war over time... with the ability to move the camera around the uncovered terrain fairly quickly, so I'm guessing there might be limited scope for unloading previously generated chunks... it'll be an ever expanding dataset (so I'll presumably have to be looking for ways to keep it light on memory) I figure I can either Create a 2 dimensional array of float (or perhaps short 64k height levels should probably be plenty) for the entire terrain, and dynamically resize the array as each x z boundary is pushed back. Generate just the terrain mesh in chunks, to keep each mesh chunk under the Unity 64k vertex limit. Create a grid manager class, which has some kind of dynamic data structure that stores map chunk objects, and instantiates them retains references to them as they're demanded, each of which would contain its own (res res) sized heightmap array. Something else? I'm assuming option 2 will have the most mileage, but what I'm most unsure about is what kind of dynamic data structure to use. I'd guess some kind of key object pair structure, where the key is built from the chunk coordinates? Assuming I'll want to access height values quickly and constantly, across chunk boundaries, for things like my mouse ray intersection method, and for pathfinding code, etc... I presume I'll need a way to access chunks that is nearly as fast as looking up arrays by indices, and O(1) complexity. Or perhaps some way of caching recently accessed chunks or chunks that the camera is near? Or pointers to them, or something? As you can probably tell I'm fairly new to the gamedev side of things, but I have a VFX background, and so know my way around 3D geometry math and basic scripting. In terms of designing structuring implementing a game, I'm a total novice though, so any pointers to relevant tutorials and such would be much appreciated. |
0 | Avoiding singletons for puzzle system Say for instance I have a puzzle with 3 switches that need to be in some configuration (say all on) in one room, that opens a door in another, with a load screen separating, so I can't link the switches directly to the door. My first thought was to create a singleton that stored the state of each "solution element" which in this case is the switches, but could be a correctly turned knob, ect. then a given "Puzzle Gate" like a locked door would check the required solution elements to decide it's own state, but I'm hesitant to use singletons for all of the commonly given reasons. What alternatives do I have to singletons that would give me the same or similar control? |

0 | FBX model for 2d sprite charachter I was following along the unity platformer tutorial. https www.youtube.com watch?v 9WhZ1svdC3Q It is great. After looking the animation I found that there was a fbx model for 2d sprite character. I just want to ask can you use 3d animation like motion capture animation once you rig a character using bone for 2d(fbx model). I search but unable to find any good tutorial of how to create fbx model for 2d character and creating maps for these 2d character. I am really confused. Thank you so much for helping. |
0 | My Earthbound like Movement Script works in Unity Gameview, but runs differently in Gamebuild First programming question I've ever made in my short journey. I'm trying to create a script which moves members of your party in a line behind you (think Chronotrigger or Earthbound). Here's a clip of what I want it to look like. Problem Everything looks fine in the Game window when I play, but when I build the game to test, the characters begin to stack one on top of each other. I assume it has something to do with Update() frames dramatically increasing the frequency with which I enqueue the positions of the leading character (although I'm not experienced enough to say for sure, clarification on this would be helpful). I've tried increasing the offset, but this solution is variable depending on the players computer fps so that wont work. I've tried running both scripts in FixedUpdate() but a lot of my other systems run on Update() and so everything stutters. I've tried enqueue'ing from an IEnumerator and waiting for .1 second between each enqueue but that stutters as well.. What I'm doing The leading character has a script called PlayerTrail which creates a Queue of Vector3s. In Update the game object's transform.position is enqueued. The following character has a script called PlayerFollower which looks at the Queue and Vector3.MoveTowards the position, then dequeues that position and repeats. Each character only looks at the trail of the character in front of it. Everything seemingly works fine and well in the Unity program, this issue only arises once I build the actual game. Code Supplied Bellow using System.Collections using System.Collections.Generic using UnityEngine public class PlayerTrail MonoBehaviour public Queue lt Vector3 gt LeaderTrail public Vector3 LastMovement private void Start() LeaderTrail new Queue lt Vector3 gt () private void Update() if (this.transform.position ! LastMovement) LastMovement transform.position LeaderTrail.Enqueue(this.transform.position) using System.Collections using System.Collections.Generic using UnityEngine public class PlayerFollower MonoBehaviour public GameObject leaderObject public int Offset public int moveSpeed private PlayerTrail leaderTrail private Animator animator void Start() animator gameObject.GetComponent lt Animator gt () leaderTrail leaderObject.GetComponent lt PlayerTrail gt () void Update() if (leaderTrail.LeaderTrail.Count lt Offset) animator.SetBool( quot isMoving quot , false) return else Vector3 direction (leaderTrail.LeaderTrail.Peek() transform.position).normalized this.transform.position Vector3.MoveTowards(this.transform.position, leaderTrail.LeaderTrail.Peek(), moveSpeed Time.deltaTime) animator.SetBool( quot isMoving quot , true) animator.SetFloat( quot moveX quot , direction.x) animator.SetFloat( quot moveY quot , direction.y) Debug.DrawRay(this.transform.position, direction) leaderTrail.LeaderTrail.Dequeue() |

0 | Can I clip a collection of geometry to render only inside a particular worldspace volume? I am making a VR app in Unity. I have a giant map that I want to display on a virtual table. The map is too large to fit on the table, and I cannot change its size. (It is a third party asset, and does not easily have that capability.) How can I tell the camera not to render the parts of the map that fall off of the table? Perhaps something along the lines of Camera.DoNotRender(new Vector3(100, 0, 0)) I have been looking into using some MonoBehaviour messages such as OnPreRender, OnRenderObject, etc. But I do not know which one can help me, if any. Ideally, the pixels behind the non rendered pixels should be rendered, but that is not my priority. The map is made up of 100s of little renderers How can I have my Camera not render specific world space pixels? |
0 | Best practice for toggling between ragdoll and CharacterController One feature of the game I'm working on is that if a character is hit with a certain amount of force, it will temporarily ragdoll, then get up off the ground after a small period of time. This character is moved by a CharacterController (CC) component. At the moment, I have the model as a child of an object with a CC component and movement script. My issue is that when the ragdoll is activated animator is disabled, the model moves independently of the CC if it ragdolls with some arbitrary force in any direction, the CC does not move with it (as you'd expect). This would be fine if the ragdoll wasn't meant to be re enabled, but it is. At this stage, the model teleports moves to where the CC is, and it looks very weird. I have tried a few different methods to synchronize the two Decoupling the CC and model. Both objects are children of a shared parent, and I added them both to an PhysicsIgnoreLayer (for now eventually if I go with this I'll probably add all the ragdoll colliders to an array and ignore them individually). When the ragdoll state is enabled in the parent, the CC is disabled and the object is teleported to the root bone every frame. When the CC is enabled, the model is teleported to the CC object every frame. See here. The issue here is that setting the position means extra Update() calls and it lags behind the controller a little. Also, because the model isn't a child of the controller, it doesn't inherit the velocity of the controller, so it needs to be manually applied. Changing the parented GameObject at runtime. Depending on the state of the character, the CC model will be parented to each other if the CC is active, the model is set as its child and vice versa using SetParent. I couldn't get this one working (the local position variable was a little confusing to me, but no configuration I tried worked for me). Conjoined CC and model. I placed the CC on the same object as the model. This isn't really ideal for me because I want greater control over the rotation and presentation of the model. I couldn't get this one working either I don't know how I could set the position of the CC without moving the whole thing. Is there a more effective way of doing this? If so, what? I feel like I am greatly overcomplicating this. Any help would be great. In an ideal situation, I could have the model as a child of the controller (or behave that way) and move the CC when it is inactive without affecting the model position. |
