0 | Load Material from file path or parse .mat file to Material Unity Is it possible to load a material from a file path? Or, otherwise parse a .mat file saved on disk to a Material usable at runtime? I had naively thought it would be possible to assign the bytes from a .mat file, as read by File.ReadAllBytes to a Material object, but that does not seem to work. |
0 | How I start a over a new game using a ui button logic code? My Hierarchy have 3 main GameObjects Game Data where all the gameplay objects are stored as childs of the Game Data GameObject. Main Menu and all objects of the main menu stored as childs under the Main Menu GameObject. Game Manager GameObject that have a script that control the game like pausing the game or go to the main menu. By default the Game Data is disabled and all the gameplay objects childs disabled too. Then when starting the game with the main menu when clicking the button to start a new game I'm just activating the Game Data object This script is attached to the Main Menu using System.Collections using System.Collections.Generic using UnityEngine using UnityEngine.SceneManagement public class MainMenu MonoBehaviour public GameObject gameData public void StartNewGame() gameData.SetActive(true) public void ResumeGame() public void QuitGame() Application.Quit() This is working for first time starting a new game. And this script is attached to the Game Manager GameObject using System.Collections using System.Collections.Generic using UnityEngine using UnityEngine.SceneManagement public class GameController MonoBehaviour public static bool gamepaused false public GameObject gameData public GameObject mainMenu private void Update() if (Input.GetKeyDown(KeyCode.P)) gamepaused !gamepaused if (gamepaused) Time.timeScale 0f else Time.timeScale 1f if (Input.GetKeyDown(KeyCode.Escape)) gameData.SetActive(false) mainMenu.SetActive(true) Time.timeScale 0f This script is working. When pressing the P button the game pause continue. When pressing the ESCAPE key the game also pause but also back to the main menu by switching the gameobjects disable enable. Now let's say I pressed the escape key while playing the game and I'm back to the main menu now I want to start a new complete game but clicking the StartNewGame ui button. The problem is that this time I don't want to just active the Game Data like I did before gameData.SetActive(true) This time at least in my logic I want to destroy the existing Game Data and instantiate a new Game Data using a prefab I already have of the Game Data. This is my logic but I'm not sure how to do it. Or something like that. The main goal is to be able to start over a new game each time clicking the StartNewGame ui button. |

0 | Unity, Player isnt following along the waypoints I have a player with a Rigidbody, I want it to follow along the Waypoints, I have a script for it I tested it first on a Cube, everything worked fine, but on my character it just moves Towards the first waypoint then stays on the first waypoint instead of going ahead.

0 | Is it possible to customize the Scriptableobject inspector for Simple level data, without the use of PropertyDrawers? I've invented an innovative, new game mechanic for Bricker Breaker Quest and want to create a quick prototype to recruit a game development team. After wasting a week researching the best way to easily represent the simple level data, I reluctantly started using Scriptableobjects. Each level is defined as a List lt Block gt , where public class Block MonoBehaviour, IComparer lt Block gt public int x public int y public int lives 0 private int pastLife 0 private SpriteRenderer spriteRenderer private TextMeshPro text private void OnCollisionEnter2D(Collision2D collision) lives if (lives gt 0) UpdateVisualState() else gameObject.SetActive(false) private void Awake()... public void AddLives(int life)... How do I properly serialize the Block object so that I can enter the X, Y, and Lives integers directly in the Inspector? As a quick hack, I created a List lt Vector3Int gt instead of the Block List and use the Z input field to enter the lives. Seems like overkill to create a PropertyDrawer just to relabel one field. Any other advice is appreciated. |

0 | why contacts length could be 0 when collision2D happens in Unity3D?

0 | Unity Animation makes object spawn at x0 y0 z0 I was making an animation for a coin in my game in Unity, and when I was testing the full game, I saw that the coin is spawning at x0 y0 z0 and is doing the animation there. Then I realized that it was the animation, that increases and decreases y position and y rotation, starting at 0. So, I need to make the animation, that increases and decreases position y and rotation y, without affecting the actual position, because it will be different the position of the coins each time. In a while I will upload a screenshot for describing better the problem. Any clue? |

0 | How do I make a slot car game? I new to game development with Unity and my first project is a slot car racer. For a realistic slot car like driving experience, I first build a track with a channel in the track and a pin on the car. This kind of works, but it does not look like a slot car, its more like a car with a pin and sometimes the physics just go crazy and kick me out of the channel. I next tried making a spline with a simple game object following the track. I attached my car to my "follower" with a fixed joint. This didn't work so well My car was tumbling and pulled sideway but I never archived that my car gets pulled down the track. How should I be approaching this? I'd like the car to accelerate and decelerate quickly, with that acceleration and deceleration controllable by the user. |

0 | Combining mesh on the fly without using gameObject I procedurally generate chunks and use the marching cube algorithm to create meshes in 3D. At first, I just created a gameObject for each cube (of course, I knew it was not optimized, but I wanted to see if the algorithm worked). For now I stock all gamesObject in child of "blocks" but it would be much more optimized to directly merge the meshes between them and only create a single gameObject. However, i did not find any way to directly merge the meshes between them. So my question is is there a way to directly merge meshes between them without having to use gameObject? (don't worry about texturing) Here's the code public static GameObject GenerateChunk(int ,, map, int chunkSize, Vector3 chunkPosition) GameObject blocks new GameObject("BlockList") GameObject newMesh int cubeVertices new int 8 create each mesh in a gameObject as child of "blocks" for (int x 0 x lt chunkSize x ) for (int z 0 z lt chunkSize z ) for (int y 0 y lt chunkSize y ) define the vertices (cubeVertices) Vector3 cubePosition new Vector3(chunkPosition.x x, chunkPosition.y y, chunkPosition.z z) newMesh GenerateCube(cubePosition, cubeVertices) if (newMesh ! null) newMesh.transform.parent blocks.transform combine every children of "blocks" and delete them MeshFilter filters blocks.GetComponentsInChildren lt MeshFilter gt () List lt CombineInstance gt combine new List lt CombineInstance gt () for (int i 0 i lt filters.Length i ) if (filters i .sharedMesh null) continue for (int j 0 j lt filters i .sharedMesh.subMeshCount j ) CombineInstance ci new CombineInstance mesh filters i .sharedMesh, subMeshIndex j, transform filters i .transform.localToWorldMatrix combine.Add(ci) Destroy(filters i .gameObject) create the chunk and set the final mesh with the CombineMeshes function GameObject chunk new GameObject("Chunk", typeof(MeshFilter), typeof(MeshRenderer)) chunk.GetComponent lt MeshFilter gt ().mesh.CombineMeshes(combine.ToArray(), true, true) Destroy(blocks) return chunk |

0 | Approximately circular range of motion on a square tile grid I've been working on a grid based tactics style game to learn the ropes of Unity. I have an issue with movement range for a player unit. Let's say the units move range is 3 spaces..

0 | How can one replicate the 'Quake Disruptor' of Wipeout XL 2097? Following my previous question, I am wondering how one can achieve the same effect under Unity? The effect in action https youtu.be kzmmLeCwL0g?t 790 Description of the effect When you fire the Quake Disruptor weapon, it creates a sine wave that mimics an earth quake, it happens over the next track sections forward to the player ship as you can see on the small video. This results in instant damage and slowdown to the ships that are caught in the quake. Technical challenges Deforming the mesh The function for generating a quake like wave to apply to each section of the track mesh is easy, e.g. a Gaussian filter will probably be good enough https www.desmos.com calculator goasdepcmv Applying the deformation to mesh This is where it starts to get trickier, a track is made out of sections that have few faces, each face being nothing more than a quad. Here you can see three sections and their faces (wall, track, track, wall) The challenge in here is how to apply the deformation and yet being able to check collisions against the track (remember that we can't use a mesh collider since it'll be updated in real time). I first thought that subdividing the mesh using tessellation would be needed to apply smooth deformations, hence my previous question. However, if you look closely at the video they simply move either edge of faces according to where they're against the 'quake' function being applied to the track mesh. Here's a link to a video with the best quality, around 13 mins 10 secs https archive.org details PSX Longplay 243 Wipeout 2097 We're getting closer but we still need to be able to check for collisions. Being able to still collide against the track This is the big question mark, since we cannot update a mesh collider in real time as it's a CPU hog, I really have no idea on how to address this part of the problem. This also leads to another problem, since we cannot use a mesh collider, how are physics are going to be handled, by writing a physics system from scratch ? Question How can such effect be achieved under Unity, if possible at all? PS You will want to remember that the PS1 had a 33Mhz CPU and certainly no mesh collider like the one we can find in Unity, yet they achieved to do it. For sure there is a trick involved but I couldn't figure it out. |
0 | How to create HDR and bloom in Unity3D? Unity3D's reference describes the HDR Bloom as Using HDR allows for much more control in post processing. LDR bloom has an unfortunate side effect of blurring many areas of a scene even if their pixel intensity is less than 1.0. By using HDR it is possible to only bloom areas where the intensity is greater than one. My question is how to achieve it in a surface shader? I have tried to output both the Albedo and Emission greater than 1, but still when I set the Threshold of Bloom equal to or greater than 1, no visible effect can be seen. The relevant part of shader snippet is float rim saturate(dot(normalize(IN.viewDir), o.Normal)) if (rim gt 0.98) o.Emission 1.5 or any large value Which basically outputs a bright white circle when view angle and normal are at almost same angle, and I want to enhance it with HDR. But outputting a value greater than 1 is not being registered and setting the threshold almost equal to 1 (0.98 or above) creates the Bloom on areas other than the bright white spot, which is not what is needed. I have tried to output extremely large values of Emission and have also tried output Albedo 1. Please tell what I am doing wrong or missing. I think I have not been able to figure out what is the meaning of pixel intensity 1 and what settings does this translate to. |

0 | How do I determine the rotation of a Tile using Tilemap in Unity 2d? I want to know the rotation of the tile in C in order to do some logic on another object that is sitting on the tile. The rotation matters for the logic. I don't see anything except GetTileData in the doc, but that doesn't actually seem to "Get" the tile data. I could cast to Tile but not all tiles are Tile. Alternatively, I think I can get the rotation if I can get the GameObject for the tile but I have no idea how to do that either from a BaseTile. Anyone have any suggestions? Maybe I'm trying to do this wrong and I should make different tiles for each orientation or extend BaseTile or some other solution instead of trying to determine rotation. Any help or ideas would be greatly appreciated! Additional info When I inspect around in the Unity editor I see that the rotation is stored in Z in something called "Grid Selection" but I can't find a programmatic way of accessing that. |
0 | World rotation independent mouselook Preface I am terrible at using quaternions right. I wanted to create a world rotation independent mouselook script. That is, no matter the 'down' for the camera, the mouselook should feel natural to the player in relation to what is displayed on screen. I now have the following script running on update in my camera Quaternion worldRot Quaternion.LookRotation(Vector3.forward, Vector3.left) xRot rotSpeed Input.GetAxis("Mouse Y") yRot rotSpeed Input.GetAxis("Mouse X") transform.rotation Quaternion.AngleAxis(yRot, worldRot Vector3.up) Quaternion.AngleAxis(xRot, worldRot Vector3.right) worldRot Unsurprisingly, it tumbles all over the place. I think the issue is in basing the rotation angles on the worldRot (World rotation as seen by the camera), while then also rotating the whole by worldRot. I cannot get my head around how else to go about it, though... My initial alternative was to use transform.rotation Quaternion.AngleAxis(yRot, Vector3.up) Quaternion.AngleAxis(xRot, Vector3.right) worldRot But this anchors the mouse's movements to the world rather than the camera, which as described above isn't desired either. Based on this (or, perhaps, in a completely different way), how do I make a mouselook system with an arbitrary down vector? |
0 | Is there a way to view all colliders in a unity project at runtime (after the game have been deployed)? I'm have created a small Unity project but physics has weird behavior (bug). Unfortunately it only happens on some specific hardware (after build), not on development machine. I don't know what is the reason it's probably due to different framerate. Viewing all object and their colliders would probably help me a lot. Is there a possibility in Unity to view all colliders in the game at run time (some kind of debug mode). Something similar as Game tab view in Unity with Gizmos option enabled, but for all objects ? |
0 | How do I draw a context menu next to my object? I want to show a menu next to an item in an inventory. This is what I try to rebuild I do this by placing a canvas in 3D world space next to the inventory As I don't want the menu to be rotated, I rotated the menu the opposite X value as the camera. The camera has an X rotation of 11, so I rotate the menu by 11 to make it look straight Since I don't want the menu to get stuck in the case, I move it closer to the camera One can see that the menu is now offset to the left and to the top because of the camera perspective. How could I offset the menu in such a way that it still aligns with the right top corner of the item? Thank you! |

0 | Preparing a 2D character to export from Blender to Unity? I'm an animator for a game currently, and I don't have Unity (can't download due to too much gigs coupled with slow internet,) but the game designer told me I can use Blender to export animations into Unity. I asked if I needed to prepare multiple files to export, and they told me that I could just have one file with all the animations in it. The game, as stated in the title, is 2D. My problem now is, how do I turn a rig into an actual character with different animations under it? (Right now I only have an 'idle' animation, but need to make running, jumping, walking, etc.) I mean how do I save this 'idle' animation and work on another animation without overwriting the previously finished animation(s)?

0 | How can I implement UI in Unity using Chromium? I'm looking for an alternative to UI Builder. Ideally I'd like to have basically a Chromium instance atop Unity3D which would have its JS calls somehow land in the C (maybe in the quot Update quot loop it listens to a constant stream of potential calls and the parameters will correspond to function names in my Unity code, I don't know) here's what I found which doesn't quite live up to my expectations Unity WebView doesn't support Windows. 3D WebView for Windows and macOS (Web Browser) requires the UI to be served on an actual live URL and for Unity to access it via that URL and for all interaction to be handled via API, impractical or slow at best. PowerUI HTML CSS is interesting, but was made in 2011. The documentation is all gone. the support for css feature is probably incredibly slim. Embedded Browser looks pretty good, but I'm unsure that it could be bent into a UI system. I want it to frame my game, not to cover it. Coherent Gameface looks probably the best, although the CSS implementation seems a tad lackluster. Also this project was started in 2012, it's probably carrying very old, very slow code. This Unity forum thread may be relevant. Chromium Embedded Framework was a tool used by some assets on the asset store to create chromium UI but it has been removed. If not using these assets, how can I implement my idea of using Chromium as my UI layer? |

0 | How to create a solid cross scene game manager in the editor of unity? I have been checking dozens of known 'solutions' for how to create a game manager in Unity, but none leave me satisfied. I know I can create a singleton GameManager.Instance() that would have data to persist across multiple scenes, but it doesn't show up in the editor unless I assign it to a game object. The problem is, this game object would then be destroyed upon loading a new scene except if I use DontDestroyOnLoad(). However, when I use DontDestroyOnLoad(), and I open up a new scene in the editor, this GameManager Object doesn't exist in the new scene. The DontDestroyOnLoad() method assumes that the program entry point will always be the main first scene, which is often not the case when working in the editor. This isn't great. Example When I have events within scene2 (say a button or something), I cannot reference the gameobjects in scene1 in the Unity Editor (most importantly, the game manager). Instead, I have to first attach a settings.cs script to my UI Button GameObject. When pressed, the Button will then call a function from the settings.cs void ChangeInput() GameManager.Instance().ChangeInput() . This feels quite clunky because the Button Element cannot reference the GameManager directly, since the Button is scene specific but the gamemanager is not. Is there a proper solution for issues like this? |
0 | Architecture for extremely modular game? I'm developing a modular game in Unity 5.6. Each module has very little overlap in assets with the others. I'm concerned about having a bloated repository after a few months of development, and since I'm using Bitbucket (a free account) I'm limited in my repo size, but not in my number of repos. So instead of having one huge folder for my game I'm considering having a launcher project and scene that loads builds from a folder in Assets. Each module would be its own project, and I would just drop its build into the launcher's folder. My question is, is this a reasonable approach to building a highly modular game? Hopefully I'll be continuing development for quite a while, and I want to make sure the project is as lightweight and extendable as possible. Or am I overthinking this, and should I just use one big repo? |
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 | Unity3d How to use controller joystick to look around? I try to use my xbox controller as input device for a game targeted to run on windows. However the documentation fails to explain how to set it up. E.g. how can I use the right stick from my xbox controller to look around, like in any 3D game? Even such a common task is not documented. I found a very old wiki entry where the xbox controller is briefly described, I was able to find out that the Y Axis of the right analog is called 5th axis (Joysticks) and the X Axis is called 4th axis (Joysticks). I post the images below, in case the link get's dead. Linux Note wired controllers only support axises for the d pad, while the wireless controller only supports buttons for the d pad, refer to the table above for the wireless controller configuration. I figured out that the name of a control is responsible for the action which the button, stick, key, pedal etc. does. But it is not documented how the control has to be named for looking around vertically or horizontaly like you can do in an 3D game to look around with the camera by using the right joystick (e.g. witcher 3) How can I control the camera by using the right joystick? |

This is a problem since I don't see how I could easily make it so that each TextLine object fills 33,3 of the canvas. Am I right to assume that I can only solve this by making a scripts that holds a reference to each TextLine object and which then calculates their position when the scale of Canvas is known?

0 | Need advice concerning the creation of open world game in Unity 3D I just wanted to ask for advice those being an expert in Unity 3d and overall in game industry about how it is possible to create an open world game by means of Unity 3D, that is, I already tried to combine several tiles of terrains, 4 to be exact, and their respective size is 500x500. However, once I started to add the fifth terrain to those terrains, Unity stopped working. Moreover, another problem that I faced was with light mapping in Unity, that is, the more terrain I add to the scene the more it is difficult to bake the light mapping. The question is if I am doing correctly by adding terrains to each other and how open world games are actually created. Yes, I heard of chunk loading but is it possible to code it on my own without using ready plugins. Lastly, Is it possible to combine tiles of terrains just manually without using any tools like Terrain Slicing kit or Gaia please I really need your help Thank you for your attention))). |

Here's a screenshot of the cave entrance in blender (which is the floor I'm looking at in Unity) All normals of the faces seems to be facing correctly, and mesh has simply been modelled by extruding edges from existing parts of the mesh, so there shouldn't actually be any actual holes.

I tried to parent it to another kinematic body, and make the child also function as a moving platform (the script only moves the parent), but it seems that the friction is ignored for the child object, and the carried object slips behind it and falls down when the child platform moves. The child platform is the same physical material as the parent. Is there any way i can make the child's friction work too, while having the script only move the parent?

0 | "Instantiate" function in Unity spawns enemy but it doesn't show up So, I'm making a top down shooter (2D) and I already made an enemy prefab. It walks to the player and damages it, and reacts to bullets physically until it eventually dies. The prefab itself is ok, because I can spawn it manually and it works as intended. The problem comes when I want to automate the spawn process with a script. So I made a script to do so, here it is using System.Collections using System.Collections.Generic using UnityEngine public class GameController MonoBehaviour public GameObject enemy private float spawnPositionX private float spawnPositionY Vector2 spawnVector Start is called before the first frame update void Start() SpawnEnemy() void SpawnEnemy() spawnPositionX Random.Range( 630f, 630f) spawnPositionY Random.Range( 340f, 340f) spawnVector new Vector2(spawnPositionX, spawnPositionY) Instantiate(enemy, spawnVector, Quaternion.identity) As you can see, it's nothing too complex. I just refer to a game object (which I linked by the way) and then create some variables that will hold the x and y positions in which the enemy will spawn at random. Then when I call the function, those positions get set and stored into a bi dimensional vector to then be used with the instantiate function. This... works... kinda? When I run the game, the instance of the enemy gets made, I can see the clone in the hierarchy and I can select it and see that it's indeed moving, but it's like... not there? I can't actually see it on the screen and it's not invisible as I can't interact with it either. It's really weird and I have no idea what's going on. I tried to put the script on the camera, on the canvas, on a new empty object, nothing. I also checked that the prefab and the instance that's being spawned are indeed active. I thought about the coordinates being out of bounds, but when I check my player coordinates they are inbounds, so that can't be it either. I'm completely lost on this one, thoughts? Thanks. |

0 | Unity Render only select objects but show previously rendered objects I am making an RTS game which is having performance issues. Is it possible to render the ground and units separately so I can only render the ground when the camera moves but keep the result displaying the units over the top? I'm not sure what details to include but The camera is fixed angle and orthographic The profiler says drawing takes up about 50 of CPU when units are moving. All the logic is done by a c script outside of monoDevelopment but called through a gameobject each frame, (takes 2 of cpu in tests). Units are put in place using the "transform.position" command each frame. Units and tiles are instantiated and destroyed when the Camera passes them. The game is using rigged .3ds models for the units. The units have disabled rigidbodies. Each tile in the game is a separate sprite. The performance drops with 100 low poly units without animation or 20 higher poly units with animation. |

0 | How to make the whole game wait until some new feature at beginning is finished? In Unity I have been working on a driving game and its almost finished. I'm just trying to add some polishing touches. Ironically this part im stuck on now would not have been any issue at all in purely code based frameworks i used before (LibGDX Xna) because I could just make a boolean that's called ReadyToPlay or something and just put that around all the code i want to wait to start. I've made a secondary camera which rotates around the players car, it works fine but my problem is that the GUI is also already loading AND the race start countdown occurs still whilst the camera is still spinning. I'm not sure in Unity how to go about stopping that to allow the time for the camera to spin. One idea I have to fix this (i'm checking first because this doesnt seem right to me) is to use the yield routine in the GUI loading script and tell it exactly how many seconds the camera is going to spin for. I'd rather have just have the camera detected when its done a full spin and then make a boolean true, or trigger another method to start the game properly. I promise I have done some research trying to find ways but the only thing i can find except yield, is Monobehaviour.Invoke but the invoke method still requires me to specify the time. The whole strategy for yield or invoke feels wrong to me. I guess my main problem is that the code is spread over a few scripts, instead of being funneled thru a main.cs and then gameManager.cs etc etc so theres no way (that I know) to break the chain higher up. I'd have to add bools to each script to say isLuxuryCameraAlive and that still seems wrong to me as I might have 5 10 scripts and have to also section of bits of code in each script. How would you experienced programmers attack this issue?? Thank you!! |
0 | Issues with 3dsmax and Unity3d scale I changed the units in Blender so they are identical to Unity 3d. If I make a 1m 3 box in Blender, it will import into unity as exactly the same size as the standard cube. With 3ds max, I changed the unit setup to metric and made sure it was centimeters in the system unit setup tab. However, when I import an obj file made in Blender and used in Unity, it is absolutely tiny. I have to convert the model to meters on import and then, when exporting, I have to set the model scale to .01 otherwise it is enormous in the unity scene. I've tried changing the max units to meters and nothing changed. How do you change the max unit grid setup so one grid unit is 1m 2 and exactly equivalent to unity's grid? |

0 | How to make Scriptable Objects derive from other Gameobejcts? I encountered a problem where I want to make a Scriptable Object that derives from another class, but C does not support multiple inheritance. Further, I do not think it would not make sense to make interfaces for this example. There is a lot of duplicate code within methods that only an abstract class could contain implementations of. Basically, I want an abstract class that models "anything that can take a turn." I call it a TurnTakeable. But I also want the TurnTakeable to be split into friend and foe derived types, as the two are slightly different. Yet they mostly have the same behavior. Is there a workaround, or do I have to make an interface? ( |
0 | Whats the best way to make my Unity game moddable? Basically the title. I'm building a game with several NPCs and complex systems, and I want it to be nice and modular for modders right from the beginning. So far, I have looked into Asset Bundles, I don't completely understand these, probably will have to write some custom loading code? I don't know how if this will let the modders write code. Lua Based Modding, I don't particularly like Lua, but I will fall back to it if I absolutely have to (The Unity Lua Plugin makes this a seemingly very fast way.) Exposed C (original idea from this Question). But again, as stated in the question raw c has a lot of disadvantages, not to mention the security risks and compatibility issues. Minecraft Style? Completely custom? Basically a lot of events and registries? I'm not sure about this option. To give you an example, there are several Tribes in the game. Ideally, if a modder wanted to make a new tribe they would need to extend from some Tribe base class and then register add their custom tribe to my AvailableTribes list. Not to mention the models, animations, and sounds for the Tribe NPCs and such. Any help is appreciated! |

0 | Weird windowed resolution can't seem to change without changing the name My game is windowed, and when I set the resolution in the build settings (960x540 16 9 Windows standalone), and build it, it works as intended, but from then on, I can no longer change the resolution (can change it in the editor, and it also saves, but when I build it, it is still the original res (960x540))unless I change the Product Name as well. When I change the product name, I can change the resolution, build it, and it will change, but then it is stuck as well. When I change back to the first name, the resolution automatically change it the resolution for the first name (960x540) (it doesn't show up in the editor, only when you build it.) So basically Name1 960x540 Name2 1280x720 Name3 1024x576 etc So you can change the resolution every time you change the name and build it, and that name is stuck with that resolution (no matter what you change it to in the editor later). I am fairly new with unity, so am I missing something very basic here? Thanks for any help! |
0 | Why do these textures tile rather than just overlap? It might help to provide all the details, so here is the YouTube tutorial which sparked my question. There's a prefab of the background tile called "Tile Background." This prefab has the default settings, except that Pixels Per Unit is set to 512, and that it has a script attached to it called BackgroundTile which hasn't even been opened. It's just there for the other script to reference. An empty object was created called Board, which has Tile Background as its tile prefab. It also has a script, Board.cs, the contents of which are here using System.Collections using System.Collections.Generic using UnityEngine public class Board MonoBehaviour public int width public int height public GameObject tilePrefab private Backgroundtile , allTiles Start is called before the first frame update void Start() allTiles new Backgroundtile width,height Setup() private void Setup() for(int i 0 i lt width i ) for(int j 0 j lt height j ) Vector2 tempPosition new Vector2(i, j) Instantiate(tilePrefab, tempPosition, Quaternion.identity) Width is set to 4. Height is set to 7. Other than that, the camera position is X 1.5,Y 3 and the aspect ratio is 9 16. My question is this why, when this is run, does Vector2(i,j) get interpreted as tiling the sprites, rather than placing the sources of the sprites in a 4x7 pixel grid, where they overlap almost entirely? There's no place where their positions get multiplied by the size of the tiles, right? Halving the pixels per unit doesn't even just halve the height of the board it stays a constant size and looks really weird, despite the board not having set dimension attributes. What's going on here? |
0 | Unity text component not updating text properly It was worked fine previously, but after some point, it's not working. This is the code.

I just want to print it to the screen, but it's always prints "Health 100" even it changes. So I printed the value to the console, but it prints well in the console and only text components was not printed properly. So I printed Time.deltaTime instead of the health and it works! Seriously, what the hell is happening? Is this a bug? If health variable wasn't changed, it should be also printed 100 in the console, but it's not! Try this to another text component, still not working. |

0 | Problem modifying GameObject in list of GameObjects Unity So I've been working on a little project that involves Valve's quot Portal quot style portals, the type where you can seamlessly see what's on the other side and walk through. I've run into a problem when it comes to teleporting an object to it's new location upon hitting the portal. I have a List lt GameObject gt that contains all the objects that are in close enough range to feasibly travel through the portal, but when I try to modify the transform.position of one of these GameObjects, nothing happens, no error messages. So I've been going through my script line by line and writing little dummy functions to test different parts of it to see where the problem lies, and everything seems to work up until I index the list and try to modify a value, nothing happens. So was thinking that perhaps the List doesn't actually contain a reference to the GameObject in the scene, but simply a copy of the GameObject's data at the time it was passed into the list. So I checked this by making the list public so that I see it in the inspector, and when I click on an item in the list it highlights that same GameObject in the hierarchy, which suggests it is actually a reference. See bellow... I am at a loss as to what's happening here and would really appreciate if anyone could offer a suggestion, Here is the dummy function where I try to arbitrarily modify the GameObject data from the List... if (Input.GetKeyDown( quot k quot )) for (int i 0 i lt trackedTravelersObjects.Count i ) trackedTravelersObjects i .transform.position new Vector3(0, 30, 0) Debug.Log( quot K quot ) You'll notice a Debug.Log( quot k quot ), this is just to check that the code is actually being called, which it is. Thanks. |
0 | Best way to constrain character to a path? I'm in the process of developing a level based runner for mobile phones, and I've hit a wall when deciding which method to use to get the character to move through the level. Basically I need my character to travel a constrained path across the level as I manipulate the character by speeding up down and jumping to avoid obstacles. I couldn't just place a straight path and use Curved World look as I needed a realistic feel to character motion. I also have up down slopes that have to affect the character's speed. I'm not use whether using iTween is the best for this as it makes it difficult to manipulate character speed and especially the jumping 'arc'. I've tried using MoveTo() but problems arose when trying to change character parameters... PutOnPath() made sense in theory but I found it harder to implement. Is there any easier way to go about this? I'm almost completely new to Unity, so an easier implementation is what I'm going for, for now. Thanks in advance! |

0 | Basic Character Controller Not Working Properly in Unity I've been trying to setup a simple mouse camera which I had all the code working fine, except when I move with wasd and move my mouse to turn the camera simultaneously the input freezes up and gets stuck repeatedly inputting whatever the last input was. I've tested the simplest way to replicate the issue and it doesn't even need a camera for the issue to come up. If anyone would like to test and try to replicate the issue these are the steps its super fast and simple. create new project(basic PC 3D project) create a plane, and a cube Add a basic character controller script to the cube (this time I used the official Unity code to be sure it's not an issue with code) and that's it, that's actually all that was needed to create the issue for me. And to explain to anyone who may want to test it the issue is as follows when you use wasd keys normally, everything works fine and the controls are responsive. However if you hold down one of the wasd keys while also moving your mouse (just wiggling the mouse should suffice) suddenly things will lock up and the cube will keep moving for a bit even after you let go of the respective wasd keys. In general if you hold a direction while simultaneously wiggling the mouse for a longer period of time, it will extend the amount of time the cube keeps moving after you let go of the direction. And this was done on Unity version 2020.1.16f1 If anyone has any idea what the issue may be its really appreciated. |

0 | How would I properly flip a character when they reach the edge of a ground object in Unity 2D? The idea here is that the raycast shoots downwards from an empty game object and when it detects that there is no ground below it the character should bounce back and walk the other way. When I get to the edge of my platform the character just gets stuck in place and keeps rotating on the Y axis. public class npcAI MonoBehaviour public float speed public float distance private bool movingRight true public Transform groundDetection raycast goes downward from this point private Vector2 movementDirection void Start() Initialise direction movementDirection Vector2.right void Update() transform.Translate(movementDirection speed Time.deltaTime) RaycastHit2D groundInfo Physics2D.Raycast(groundDetection.position, Vector2.down, distance) if (groundInfo.collider false) if (movingRight) movingRight false movementDirection Vector2.left transform.localScale new Vector3(0.30F, 0, 0) else movingRight true movementDirection Vector2.right transform.localScale new Vector3(0.30F, 0, 0) The code above was edited to reflect the answer below. If you find yourself attempting to do the same thing and need to flip your sprite when you reach the edge change 0.30F to whatever double the X value of your sprite is in order to flip it. My sprites scale was (0.15, 0.15, 0) so I used 0.30F to flip my sprite. Be mindful of when you should use and when you should use . |
