0 | Unity How to add a shader to a material via c script? I found already some things but those seem not quite what I need. (perhaps outdated functions?) https docs.unity3d.com ScriptReference Material shader.html here, it seems you can add a shader to a renderer using UnityEngine using System.Collections public class ExampleClass MonoBehaviour public Shader shader1 public Shader shader2 public Renderer rend void Start() rend GetComponent lt Renderer gt () shader1 Shader.Find("Diffuse") shader2 Shader.Find("Transparent Diffuse") void Update() if (Input.GetButtonDown("Jump")) if (rend.material.shader shader1) rend.material.shader shader2 else rend.material.shader shader1 well i dont have a renderer. i only have a material. and there is no "material.setShader" , only a material.setTexture" sooo can anyone solve this mystery of how to add a shader to a material via script? |
0 | Change value in arrays in array The title might be confusing and I don't think this short explanation is 100 accurate, but I will try my best to show the problem.

0 | Unity Client and Multiplayer Networking Architecture My background is in Enterprise and SaaS web infrastructure. Zero information about games and how their networking works. I only know about the world of browsers and RESTful APIs. I'm planning on using Unity for the client FYI. Authentication and Authorization I'm planning to use Unity and Firebase. Seems like this is fairly standard HTTP connections during the auth faze. Nothing surprising here unless there is something I missed. The client authenticates against a service, Firebase in this case. And then all future calls after authentication are made using the returned credentials. Gameplay and Player State This part confuses me. I assume shooters use a UDP type protocol or some proprietary protocol on top of UDP. But can a game use a REST API and HTTP or TCP connections to send client updates? Clients would then poll the game server or have a long running connection open to request updates. For example the Auction House in WoW. Is there a long lived TCP connection open between the client and the server updating the auction house data every X seconds? Then when a player submits a purchase order that same long lived TCP connection is used to update the game server state? Or is it all literally a REST API like a SaaS app would use? Is my experience with browsers and Single Page Apps in an Enterprise environment applicable to a WoW auction house type situation? Thank you, Any tips or feedback is helpful at this point. |
0 | Help understand Z value of CameraToWorldPoint I do not understand what this CameraToWorldPoint function is used for, what is the use case of this function 1.From my understanding, my cursor is sitting on the near clipping plane, so I am actually clicking all the points on the near clipping plane, the near clipping plane represents my screen, am I right? 2.When I use this function to convert B point to world point, I am getting the point C position, is that true? 3.Is part A gt C represent the Z value, or part B gt C is the Z value? 4.Then finally, is this function useless? Because I get a world position in the predefined Z position, and I do not even know what Z value should be in the first place, I can randomly assign a pointless Z value, so what is use case for this function, I know raycast can do anything I want, but when to use this function? |
0 | How do I use GetComponent on multiple children? I'm a beginner and I'm making a game in Unity where I set random colors for four enemies.

0 | Efficient way to store information about neighbour chunks I've finally managed to implement an infinite chunk loading system for my voxel engine. Since every chunk needs to have information about the border of the neighbouring chunks, I need to access them fast. First some information about how I'm storing the voxel data I have an Integer array of block information on each chunk (rather than byte because of the read write access speed), which is stored in an Dictionary(Vector3i chunkPos, Chunk chunk). When building a chunk I have to access the voxel data of the chunk and of the neighbouring chunks several times. Without information about their neighbours it currently looks like this So I've tried the following two things getting the chunk data every time like this public static int getBlockAt(int x, int y, int z) Vector3i chunkIndex new Vector3i( x gt gt ChunkManager.logChunkSize, y gt gt ChunkManager.logChunkSize, z gt gt ChunkManager.logChunkSize ) if (chunkManager.chunkData.ContainsKey(chunkIndex)) return chunkManager.chunkData chunkIndex .data x amp ChunkManager.chunkMask, y amp ChunkManager.chunkMask, z amp ChunkManager.chunkMask return 0 storing chunkSize 2 information on each chunk, which makes editing much, much slower, but improves chunk loading alot In general I want to implement something like using approach 1 only when the block data isn't on the chunk. I really don't know how I could do it! Do you have an idea, or experience from writing voxel engines? Thanks in advance! |
0 | Game 30 done on HTML5. Maybe it was a bad idea. Should I change to Unity3d? I'm creating a 3d game on HTML5. It's 30 complete and the hard part is already coded. The server is on node.js.Now I'm realizing that maybe it was not a wise choice. This is because I realized Three.js still has many bugs. I don't see the same thing on every machine. Each browser, OS, can give different results. I'm afraid my clients will have a great stress installing my game properly. I have tons of sprites and models on my game. I wonder if my clients will have to load all them again everytime they want to play? I wonder if a Node.js server will be fast enough to handle it, and I'm afraid it won't be scalable. What would you advise me? Should I continue and finish the game on HTML5 or is it better to remake it on something else, like Unity3d for the client and (what?) for the server? |
0 | Center Gravity in Unity a 2d planet in the center, where the players will be able to walk on it and also will be affected by center gravity. planet will be static and there won't be any other planets. so Is there a way that I can change the gravity position? yes you can adjust gravity via project settings but I want it to be in the middle x,y,z(0,0,0) I have tried creating my own gravity but it wasn't very useful because objects wouldnt fall, stand on foot and also in contact with another object they would vibrate instead of standing still.

0 | Inconsistent CapsuleCast Collision behavior when a GameObject is selected My gameobject has a CapsuleCollider and I use CapsuleCast to check for horizontal collisions when moving horizontally so the gameobject won't pass thru obstacles. It works 100 of the time except when I select the gameobject in Hierarchy. When I have the gameobject selected, whenever I try to bump a wall continuously, it shakes jitters until it eventually goes thru the wall. But this only happens when I have the object selected in Hierarchy. If I click on the scene so that the object is not selected and do the exact same thing (bump a wall continuously), there is no shaking jitter and it doesn't pass thru the wall no matter how long I bump it. This passing in the wall when selected is also consistent. Hundred percent of the time it will pass thru when I have it selected (and does the shaking) and also hundred percent of the time it doesn't if I don't have the object selected. Shouldn't selecting an object don't have any effect on this? Please give me some ideas of why. |

0 | Synchronization problem with Visual Studio 2017 and Unity 2017.1.1f Sometimes I need to change a lot of files and Clean and Rebuild the Solution to get the changes on Unity, am I missing some configuration on Visual Studio or Unity? I uninstalled everything and make a clean install and few days later I'm getting the same problems.

The class name and file name are the same, with no syntax errors. Some times opening a file with an external editor changing the encoding, cleaning and rebuilding the project solves the problem, but just sometimes and I'm tired of do that for test any change, now I have a lot of Debug.Log just to check if Unity is getting my code changes. Any suggestion will be very greatful |
0 | Unity What changes to a game object trigger baked lights to need a rebake?

0 | UNET Performance of (many) Kinematic Rigidbodies I am building a game in Unity in C using the UNET networking elements. I am trying to figure out what is the performance cost of kinematic rigidbodies? My understanding is that, when kinematic, rigidbodies are outside the physics system and therefore are not as resource heavy as non kinematic rigidbodies. For my game, I will need to use a lot of kinematic rigidbodies in the scene, because they are used to detect collisions between player placed objects (with box colliders) and the rigidbodies. All the objects instantiated in the scene will therefore need a kinematic rigidbody to allow this collision checking to take place. Thanks very much for your help. |
0 | How do I make an infinitely scrolling background? I am trying to make a game where a torpedos keep coming from random directions and the player has to maneuver a submarine to escape them. I am currently offsetting the background to give it an illusion that the submarine is moving i.e. if the submarine moves forward, I move the background (quad) backwards. This is primarily being done as I want it to be an infinite space. The position of the submarine does not change, the player just controls the rotation of the submarine and the background moves in the opposite direction. The background is set to repeat to give it an infinite space illusion. The torpedo gets spawned at a random distance and moves towards the submarine. Since, the position of the submarine does not change, the torpedo will always hit the submarine. How do I structure this game, specifically the background repeat so that I can actually move the submarine in absolute dimensions and still maintain the infinite space illusion? |

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? |

The Problem I want to click on different objects and send the knight towards whatever object I click on. The knight does NOT move, though the object I click on registers a click (all objects have colliders). Is Raycast the most appropriate way to do this? Checking another users question similar to mine, (how to move one object to another objects position) they seem to use a method similar to "Vector3.MoveTowards". EDIT Moving my code from "OnMouseDown" to "Update" solves that issue. but is there a reason why OnMouseDown won't work or even how to make it work? I was trying to limit my code from going into Update as that's called every frame. |

However I want all the units to maintain the same relative position to the leader throughout the behavior ie say for example if one of the unit falls far behind the group due to an obstacle in its path, it should converge back to the main group to its initial relative position so that the formation of the group is not broken and stays the same throughout I have stored all my units in a list and offset them from the leader at the start of the game.

0 | Is there a way to display navmesh agent path in Unity? I'm currently making a prototype for a game I plan to develop. As far as I did, I managed to set up the navigation mesh and my navmeshagents. I would like to display the path they are following when setDestination() is fired. I did some researches but didn't find anything about it. EDIT 1 So I instantiate an empty object with a LineRenderer and I have a line bewteen my agent and the destination. Still I've not all the points when the path has to avoid an obstacle. Furthermore, I wonder if the agent.path does reflect the real path that the agent take as I noticed that it actually follow a "smoothier" path. Here is the code so far GameObject container new GameObject() container.transform.parent agent.gameObject.transform LineRenderer ligne container.AddComponent lt LineRenderer gt () ligne.SetColors(Color.white,Color.white) ligne.SetWidth(0.1f,0.1f) Get def material ligne.gameObject.renderer.material.color Color.white ligne.gameObject.renderer.material.shader Shader.Find("Sprites Default") ligne.gameObject.AddComponent lt LineScript gt () ligne.SetVertexCount(agent.path.corners.Length 1) int i 0 foreach(Vector3 v in p.corners) ligne.SetPosition(i,v) Debug.Log("position agent" g.transform.position) Debug.Log("position corner " v) i ligne.SetPosition(p.corners.Length,agent.destination) ligne.gameObject.tag "ligne" So How can I get the real coordinates my agent is going to walk throught ? |

0 | Random Object in Array I am using Unity. I have created eight different types of objects, stored in an array, and I am displaying them on the scene in a grid pattern with random order. The first four objects in the array are red. The player needs to destroy all four red objects to go to the next level. The code I've writted so far uses the Random.Range method, which chooses objects completely randomly. Sometimes it generates a grid that doesn't contain four red objects, so my player can't destroy them and proceed to the next level. How do I randomly generate this grid so that it is guaranteed to have exactly four red objects? Here is my code. public int gridWidth 0 public int gridHeight 0 public GameObject facePrefab new GameObject 8 void Awake() gridHeight Random.Range (3, 5) CreateGrid(gridWidth,gridHeight) void CreateGrid(int numX, int numY) for (int x 0 x lt gridHeight x ) for (int y 0 y lt gridWidth y ) GameObject go Instantiate (facePrefab Random.Range(0,facePrefab.Length) ) as GameObject |
0 | How can I render from a buffer that exists and was created on on the GPU? I'm looking for a unity API or function call to allow me to do the following ... I wrote some really complex functions that are compute shaders. These compute shaders manage a huge compute buffer containing voxel information. I then take portions of (or the entire) voxel buffer in another compute shader and produce a vertex buffer. All of this is done on the GPU with only compute shader calls from the CPU. Now I want to render that vertex buffer but I must be looking in the wrong place because I can't find any information on how this is done within unity despite there being other examples on how to do this using raw DX or openGL approaches. Can anyone point me in the right direction to determine how I can render using a specified shader a buffer already in graphics RAM (and ideally give it some textures too)? |
0 | Command pattern for network games I am currently programming a multiplayer game. The basic idea is that the game uses Command Pattern for any actions that happens in the game. If the player right clicks to move then a command is issued to the selected object to move to the location. I implemented gRPC to include multiplayer. Here is my problem, when the player right clicks on the ground I send a gRPC call with that command then the server acknowledges the commands and sends it back to all the clients, the client then processes the command and everything goes well. Now if the player enters the game while a command is underway the client never received that command so its never process on the client. What would be a good way to fix this problem without sending the info of all the actors (x,y,z) and what they are doing at each server ticks? Thanks! |

0 | How to create a 2d jelly soft blob body? I'm a developer looking into game development. I have an idea that requires a 'character' that needs a jelly like body. I've found this video which really demonstrates what I want. I've looked around and there are libraries assets that do this (like Jelly Sprites) but none state how they do it, and that's what I'm interrested in. What I've read so far is that a way of doing it is using multiple rigid bodies joined with joints that don't collide with each other. Witht he common sidenote that it might not perform that well. I'm hoping anyone has any pointers or tutorials that explain the concepts of jelly soft blob bodies. Any pointers towards achieving the effect shown in the video would be awesome. |

0 | How to restrict the players movement win relation to screen bounds in Unity? (Without colliders) I am really enjoying making the switch to Unity. But here I have found one of those rare moments where it appears to make things more difficult (at least it is for me as I am crap at understanding the actual manual) Basically my 'player' is a space ship. It starts life at 0,0,0 world coordinates and I have been doing all the movement based off of that. (ie. Add force X to move left or right, and there is a constant Z speed which is done via rb.transform.Translate().) I want to restrict the movement on the X Axis, so in Libgdx id use something like if (player.position.x lt 0) player.position.x 0 if (player.position.x gt viewport.getX()) player.position.x viewport.getX() The thing is that wont work for me in Unity for several reasons (1. I dont know much about the viewport as I didnt create it. 2. the player.position is being affected by the rigidbody forces. AND i am working in world coordinates with the players position). As I said, the player is constantly moving forward on Z axis, so making colliders doesnt seem like the right choice for me. I'm pretty sure Unity devs would of put this in Unity v0.001 but I just cannot for the life of me find how to actually do it. (Any info I can find seems from like 2011 and also is pretty badly written code making this simple matter takes dozens of lines of code and some methods I'm hoping there is a Unity method already made, like player.transform.ScreenPosition or something but yeah I cannot find it!? Any help would be massively appreciated as always. |

0 | Networking assigning IDs to entities Maybe I'm asking dumb question, but this problems bothers me... So I have my networked game in Unity (client), and server written in C (without Unity). I Use ENet library for networking. Most of networked components are written by myself (lobby, components etc.). Server doesn't know about Unity entities like players, obstacles etc. In most cases I send message ("hide object with id 4") to the server, and server pass that message to other clients where they applied message information. What my problem is, how to assign proper IDs to networked objects, that will be the same across all players? What I do is that On all clients I get all components with specific network component (e.g. NetworkRigidbody) I sort all of objects using special comparer which compares based on component name with all parents appended to it ID is just an index in sorted array Above algorithm works, but I have a feeling that in normal games that problem is handled in other manner. I searched over Mirror, MLAPI and other libraries source code and I couldn't find how entity id is generated, especially when server is not Unity application. |

0 | Unity Tilemaps Best practices I'm pretty new to Unity and I just finished some courses and tutorial found in the official documentation. I'm now in the process to apply what I learned so far using different assets from the ones provided with the tutorial, to see if I understood all the material. I'm trying to build a simple top down game with some free asset I found online. My tile palette is composed, among others, of tiles like these Now, in order to create something like this sorry for the quality, I recreated it in gimp since I'm not on the computer where I have Unity now I had to create three Tilemaps under the same Grid. The botton tilemap contains the grass (sort order 2), the middle one contains the fence (sort order 1) and the top one contains the house (sort order 0). My first question is given the tileset I have, is this the most efficient way to obtain what I needed? After having solved this problem I wanted to add a collider to the fence and to the house, but since they are on two different tilemaps I cannot use a composite collider to optimize the collider's layout. Is there another way to do this in a more efficient way? Instead of using tiles for quot interactable objects quot , should I use quot proper quot game objects instead? |

0 | In Unity, how do I correctly implement the singleton pattern? I have seen several videos and tutorials for creating singleton objects in Unity, mainly for a GameManager, that appear to use different approaches to instantiating and validating a singleton. Is there a correct, or rather, preferred approach to this? The two main examples I have encountered are First public class GameManager private static GameManager instance public static GameManager Instance get if( instance null) instance GameObject.FindObjectOfType lt GameManager gt () return instance void Awake() DontDestroyOnLoad(gameObject) Second public class GameManager private static GameManager instance public static GameManager Instance get if( instance null) instance new GameObject("Game Manager") instance.AddComponent lt GameManager gt () return instance void Awake() instance this The main difference I can see between the two is The first approach will attempt to navigate the game object stack to find an instance of the GameManager which even though this only happens (or should only happen) once seems like it could be very unoptimised as scenes grow in size during development. Also, the first approach marks the object to not be deleted when the application changes scene, which ensures that the object is persisted between scenes. The second approach doesn't appear to adhere to this. The second approach seems odd as in the case where the instance is null in the getter, it will create a new GameObject and assign a GameManger component to it. However, this cannot run without first having this GameManager component already attached to an object in the scene, so this is causing me some confusion. Are there any other approaches that would be recommended, or a hybrid of the two above? There are plenty of videos and tutorials regarding singletons but they all differ so much it is hard to drawn any comparisons between the two and thus, a conclusion as to which one is the best preferred approach. |

0 | Unity Transforming horizontal distance between two spriteRenderers to set UnityEngine.UI.Button width to this distance In my Unity scene, I have a couple of spriteRenderers and a UnityEngine.UI.Button called thisButton. The spriteRenderers are spread horizontally across my scene. I want to change the button width to span from the leftmost spriteRenderer to the rightmost spriteRenderer. To do this, I have subtracted the x Coordinate of the rightmost spriteRenderer (fRightEndingPosition) from the x Coordinate of the leftmost spriteRenderer (fLeftStartingPosition). float fLeftStartingPosition leftmostSpriteRenderer.transform.position.x float fRightEndingPosition rightmostSpriteRenderer.transform.position.x float fButtonTargetWidth fRightEndingPosition fLeftStartingPosition Then, I try to set the width of thisButton to the value of fButtonTargetWidth by doing RectTransform buttonSize thisButton.GetComponent lt RectTransform gt () buttonSize.SetSizeWithCurrentAnchors(RectTransform.Axis.Horizontal, fButtonTargetWidth) However, when I try to use this as the width of my button, the result is not correct. I am pretty sure this has something to do with different types of coordinates being used for the spriteRenderers and the button (world, screen, viewport, etc.), but I haven't been able to figure this out on my own. In one specific example fLeftStartingPosition is 1.1, and fRightEndingPosition is 1.1. In my scene, a button that spans this distance has a width of roundabout 40 on its RectTransform. So clearly, setting the width of this RectTransform (buttonSize) to fButtonTargetWidth (2.2) in code results in a button that is way to narrow. In fact, after setting it's width to 2.2, it is not visible at all. How do I transform this distance of 2.2 to the desired width of roundabout 40, in a way that this distance would be transformed correctly, no matter what the actual value of fButtonTargetWidth is? |

0 | Project transfer, will re importing all my models damage my project at all? Recently I had to transfer my Unity game project to another computer and downloaded the same version of Unity I was using for my 3D project and checked that all the files and folders were in the same place and everything. When I start up the game though my models have vanished and in the hierarchy it just says missing prefab instead of telling me what it was, like it used to if I'd move a model to another folder or something like that. It shows all my files there and I was about to reimport them all but I got a warning that said "Rebuilding assets is only if your project has been corrupted due to an internal Unity bug. It can take several hours to complete, depending on the size of your project. Please submit a bug report detailing the steps leading up to here." I am sure that re importing all my models will fix this but I want to ask if this will have any negative effects on my project or possibly damage anything? This game is extremely important to me and I've been working on it for the past 3 years(being self taught which is why it's taken so long and I'm still learning) Thank you guys in advanced! D |

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 | Why can't I rotate anything to be "more than 360 degrees or less than 0 degrees"? I've been trying to make an animation in Unity, but most assets already come bundled with everything facing at 0 degrees, not to say it's a bad thing. However, the problem I'm facing is that the animation keyframes aren't playing out correctly. When this is done with raw measurements (simply dragging the XYZ rotations), negative and greater than 360 degree angles are taken account. But then again Unity could be simply remapping them, whcih is not the case. For example, the prop robotArm prefab, found within Unity's Robot Factory asset pack has a rotator script that simply rotates the whole thing along the Y axis. void OnFixedUpdate() transform.Rotate (new Vector3(0, rotateSpeed Time.deltaTime,0)) Meaning that after slightly more than a full revolution, the Y rotation value should be more than 360 degrees, which it does end up becoming... Eventually. Thinking that was possible, I tried to mimic this behavior by making the arm rotate 720 degrees (twice) in an animation file (this is not using the rotator.cs script attached to the body in the example above). Instead, all I ended up was the arm's body staying still as 720 is the same as... 0 degrees in rotation changes. So, I tried a second experiment trying to rotate from 359 degrees to 1 degree (or 1 to 1 degree). Just like above, it didn't go to plan. When the animation is run, it simply runs from 359, through every angle in between before reaching 1, instead of 359, 360 (0) and 361 (1). If you don't get what I mean, see the diagram below. So, I was wondering, is there a way to allow for such rotation to be defined in an animation curve? Every time I try doing it, any value greater than 360 (or lesser than 0) is replaced by its co terminal counterpart that's between 0 and 359.999999...999. |

0 | Unity Import a mesh that only has vertex and edge data but no faces I am working on a game that requires meshes that only have edges and vertices but no faces. In blender, you can make a mesh with only edges and vertices, but if you export it to FBX or OBJ, once it is imported into Unity, the resulting prefab has no mesh data linked to it. The prefab has no MeshFilter. It's as if I imported an mesh with absolutely no mesh data. For example, if I create a plane in Blender and then delete the face but leave the edges and vertices, and then export as OBJ, I can open the OBJ in a file editor. This is a square with no faces Blender v2.78 (sub 0) OBJ File '' www.blender.org mtllib egdes.mtl o Plane v 1.000000 0.000000 1.000000 v 1.000000 0.000000 1.000000 v 1.000000 0.000000 1.000000 v 1.000000 0.000000 1.000000 l 3 1 l 1 2 l 2 4 l 4 3 So it appears that OBJ actually does export with the correct mesh data, however, it seems that Unity does not know how to import an OBJ if there are no faces. Does anyone know if anyone has come up with a solution to this problem yet? If not, I guess I'll just have to write my own parser. If that's the case, does anyone know if there is a way to extend or override Unity's built in OBJ parser? |
0 | How to find intersections using MapBox Unity SDK I'm currently using MapBox's Untiy SDK, which allows me to render 3D Buildings and roads. I want to place a gameobject at each intersection in an area. But, I'm having trouble finding a good way to do that. The roads are gameobjects attached to a quot Tile quot gameobect. The roads have a local position 0,0,0 with meshes on them that dictate their rendered position. A long road can cross multiple tiles, and thus the same quot road quot may exist as two or more gameobjects on two or more tiles. The Mesh itself is rectangular prism extruded from some line data by Mapbox. I have tried to use colliders with no success. For one, in order to get points of intersections between two colliders, they need to have rigidbodies attached to them and it's too expensive to do that, since there are hundreds of roads. Furthermore, many of the meshes have bad verts in them, which wont allow mesh colliders to work anyway, and box colliders wont work for non straight roads. Some road meshes are sprawling, twisting, and winding and could quot collide quot with a number of roads without actually touching them. I am not above brute force looping through every mesh's vertex in every tile to detect intersections, but I am as of yet unsure of the best way to do this or if it is necessary. I am also not sure if MapBox has some hidden feature for this the way Google Maps Unity SDK allows for access to the road lattice and intersections. If I could get some info about the line that represents the road, it would be easy to tell if roads overlap. The best way I can figure is to loop through the verts on a road to determine if the lines between verts overlap that of the roads within the same time, but am not sure if that is the best course of action |

0 | Animator.SetBool am I supposed to call it only when its value changes? I've searched around the web for a while, but didn't manage to find anything about it. Despite using Animator in several projects so far, I've never been in this exact situation, so I'm unsure what to do. Does calling Animator.SetBool have any performance issue, so that I'd better call it only when its value has changed, or when its value doesn't change it's so quick that I can call it every frame? Keep in mind that, due to the nature of this question, I don't care if it's slow when I change its value, I only care if it's slow when it's false and I call it to set it to false again (same thing for true ofc). |
0 | Sort Textures by name before looping through them im using a system to get textures from the device persistent data path and assign them to an array in order to show them in the game scene.

Now in both Unity editor and my phone everything works fine and no matter how many times i load the level its the same image. Whereas on my wifes it either skips a couple of images from the array (displaying the 5th for instance as index 1) or everytime i open the level i see a different one! Thank you! Edit it seems my problem is that i need to sort them out before assigning them to that array so any help would be appreciated! |

0 | Unity, Pixel Perfect and Scaling I am totally stuck on with pixel perfectness of the game. I have tried a few pixel perfect camera assets, but they have lots of issues considering scalability. is it normal that these cameras zoom in and out, instead of scaling the camera screen when using different resolutions for the game. Because this is a huge problem for me, cause i need to make a game for aspect ratio of 16 10, and every resolution that has the same aspect ratio is needed to scale it correctly keeping the pixel perfectness. The ortographic camera size is dependent of screen width (width PPU 2) So it always zooms in or out with different resolutions. Question is Is there a way to make it scale the game sprites instead of zooming the view? |

So how do I get my Nav Mesh Agent to ignore clicks made on a particular UI element? How about ignoring clicks made to any and all UI elements? Thanks. |
0 | Limit a scrollbar's OnValueChanged to full step intervals only So I have done some research on the matter but I can't find anything. I created a UI scrollbar and asigned 10 steps to it.Then I noticed that the values of the scrollbar does not change in reference of the handle's steps but in reference of the pointer's position(like a slider).That seriously slows down the performance since it has a lot more to process "onValueChanged" and it is unnecessary for what I am trying to achieve. The values of the steps should go step 1 0.1(1),step 2 0.2(2) etc.I need to get these values and nothing in between or the step that the handle is currently on. How can I do that ? |
0 | How to transition between "rooms" virtual cameras on a button press? I'm trying to make a game that navigates like the example here I'd like it so that after combat, the player can push the button corresponding with an exit (left, right, up, down) and navigate like in this game. Also I eventually hope to randomize each run of the game so it would hopefully have some flexibility outside of being hard baked. I've seen examples of it being done with a player object and a collider, but the player won't actually be moving their character. I like this style of navigation because I think it still provides the joy of exploration for the player, but is more friendly of a navigation system for a novice like me. How would I implement something like this? |
0 | How do I load Player position as new gameobject? I want to make game like time travel, the player has the ability to go to the future by limited time, for that, I want to add some game mechanic like save the player position. Additional information ignore the red text. When pressing the button the player will create a new platform and immediately teleport to the original position. After the player teleported, the player will save the new platform as the new teleport position. after 2 seconds or pressing a button. the new platform will disappear and the player will return to the platform position. I have this playerController Script and I already implement the save position, but I don't know how to make it like what I explain. public Rigidbody2D theRB public float speedMovement public GameObject prefabGameObject Space(10) private BoxCollider2D boxCollider2D SerializeField private LayerMask GroundMask public float jumpVelocity Space(10) public float past public float future Space(10) public float hor Start is called before the first frame update void Start() theRB gameObject.GetComponent lt Rigidbody2D gt () boxCollider2D transform.GetComponent lt BoxCollider2D gt () Update is called once per frame void Update() PlayerPosSaveLoad() PlayerMovement() PlayerJump() public void PlayerMovement() hor Input.GetAxis( quot Horizontal quot ) if (hor gt 0 hor lt 0) theRB.velocity new Vector2(hor speedMovement Time.deltaTime, theRB.velocity.y) if (hor gt 0) transform.localScale new Vector2(1f, transform.localScale.y) Animation Debug.Log( quot ToTheright quot ) else transform.localScale new Vector2( 1f, transform.localScale.y) Animation Debug.Log( quot ToTheLeft quot ) public void PlayerJump() animation if (isGrounded() amp amp Input.GetKeyDown(KeyCode.Space)) theRB.velocity Vector2.up jumpVelocity public bool isGrounded() float extraHeighText .1f RaycastHit2D raycast2d Physics2D.BoxCast(boxCollider2D.bounds.center, boxCollider2D.bounds.size, 0f, Vector2.down, boxCollider2D.bounds.extents.y extraHeighText, GroundMask) Color raycolor if (raycast2d.collider ! null) raycolor Color.green else raycolor Color.red Debug.DrawRay(boxCollider2D.bounds.center, Vector2.down (boxCollider2D.bounds.extents.y extraHeighText), raycolor) return raycast2d.collider ! null SerializeField private Vector2 saveThisPosition public void PlayerPosSaveLoad() if (Input.GetKeyDown(KeyCode.E)) saveThisPosition transform.position SpawnGameObject() if (Input.GetKeyDown(KeyCode.Q)) SwitchWithsavedPosition() Destroy(prefabGameObject) private void SwitchWithsavedPosition() Vector2 temp transform.position transform.position saveThisPosition prefabGameObject.transform.position temp public void SpawnGameObject() Instantiate(prefabGameObject, transform.position, transform.rotation) And this is the Camera Script because connected with the player. lang cs public Transform Player Start is called before the first frame update void Start() Update is called once per frame void Update() transform.position new Vector3(Mathf.Clamp(Player.position.x, 7.3f, 7.3f), Mathf.Clamp(Player.position.y, 1f, 2f), transform.position.z) |
0 | Unity adding objects through script to scrollview (SetParent) Objects overlap I need to add X objects to a scrollview. I do it like this GameObject statsObject Instantiate(instance.statsObjectPrefab) statsObject.transform.SetParent(statsParent.transform) statsParent is the content container if the scrollview. Scrollview Viewport Content This is statsParent In the pause I see that then objects are added successfully, but they all overlap and no scrollbar is visible. The content has a content size fitter and a vertical layout group, but I tried now all settings and the result is always the same. I use Unity 2019.2 |
