0 | How can I assign a layer to tiles on an individual level? I've just started out with my first game in Unity. It's a simple 2D Platformer with a tile based level. When coding in the movement, I used the Physics2D.OverlapCircle() and an empty to check whether my player was touching the ground. However, I need to use a layer to make sure only the ground is detected. my code below fixed update used for physics calculations void FixedUpdate() right or left arrows being pressed float moveX Input.GetAxis( quot Horizontal quot ) Vector2 moveDir new Vector2(moveX playerSpeed, rb.velocity.y) rb.velocity moveDir update used for spacebar input and force void Update() if (Input.GetKeyDown(KeyCode.Space)) rb.velocity Vector2.up jumpForce Time.deltaTime is my circle overlapping any other colliders Collider2D collider Physics2D.OverlapCircle(feet.position, checkRadius, groundLayer) Debug.Log(collider) When I tried assigning layers to my tiles, I couldn't find a way to do it. I would be really grateful if anyone could show me how to, or if anyone can tell me a more efficient way to deal with jumping in a 2D platformer. |
0 | Unity Duck volume of audio source inside a boxed area I'm trying to lower the volume of an outside ambient wind sound while the player is inside a building or room. Is there any way in Unity to do this without scripting? Or would I have to script this to check whether the player is in a certain collider to duck (or lowpass filter) the sound? The room is seamlessly in the scene's outside environment. Any ideas on this? |
0 | Making a master server in Photon Unity Network? I am trying to make a game that requires a dedicated server running 24 7 and I would like to use Photon Networking but can Photon Network handle do a dedicated server setup? The reason I ask is because every tutorial I watch read is talking about client hosting and not server to client. Another question I have is that if PUN can handle dedicated servers will I have to make separate applications, one for the server and one for the client? To me that seems to make the most sense. The third question is that if I do have to make a server and client application how do I connect to my server application with my client application? Does PUN provide a URL which I can connect to or is there something else that I have to do? If you guys have any tutorials you could point me to working with PUN and dedicated servers that would be awesome and if you guys have any information you are willing to bestow upon me that would be greatly appreciated! |

0 | How can I combine my scrolling effect with the vertex lit shader? I want my shader to work in both Forward and VertexLit rendering modes. I'd written a texture scrolling shader, but I also want to consider lighting which is produced by Vertex lit shader. I can't add my effect directly in the vertex lit shader, so I'd created 2 passes the lighting one and the effect one. Here's my code now SubShader Tags "RenderType" "Opaque" "LightingMode" "Vertex" Pass Name "Hardware lighting pass" Tags "LightingMode" "Vertex" Zwrite On Cull Back Material Diffuse Color Lighting On At the second pass we'we turned the multiplicative blending on to combine our texture effect with the ightin that has been couputed at the previous pass.

0 | C Network flooding I just created a simple MMO in unity3d, then me and my friends test it via LAN and the result is very smooth. But when I hosted it in public (100ms ping) the server became unresponsive and causes random disconnection. Host Setup 1gbps 32gb ram 256 ssd off firewall Server Setup max of 100 players every 100ms update no other updates, just only X and Y location of player by index c sockets w async Server Flow when 100ms tick reaches, server sends position of player base on index in a loop. ex. if (gtick gt 0.1f) for (x lt maxPlayers x ) check ifs couples of ifs here... send sendToWorld(x ... player x .posX ... player x .posY) somewhere, gtick 0, then counts up again... then the result is delay, unresponsive, and random disconnection. maybe it flooding itself, I don't know. but when we test it locally (10 players), it is very smooth and no problem at all. My question is, How can I update all players every 0.1 without server flooding itself? |
0 | Check if a game object's component can be destroyed Developing a game in Unity, I'm making liberal use of RequireComponent(typeof( ComponentType )) to ensure components have all dependencies met. I'm now implementing a tutorial system which highlights various UI objects. To do the highlighting, I'm taking a reference to the GameObject in the scene, then I clone it with Instantiate() and then recursively strip away all components which aren't needed for display. The problem is that with the liberal use of RequireComponent in these components, many cannot be simply removed in any order, since they are depended on by other components, which have not been deleted yet. My question is Is there a way to determine whether a Component can be removed from the GameObject it is currently attached to. The code I'm posting technically works, however it throws Unity errors (not caught in try catch block, as seen in the image Here's the code public void StripFunctionality(RectTransform rt) if (rt null) return int componentCount rt.gameObject.GetComponents lt Component gt ().Length int safety 10 int allowedComponents 0 while (componentCount gt allowedComponents amp amp safety gt 0) Debug.Log("ITERATION ON " rt.gameObject.name) safety allowedComponents 0 foreach (Component c in rt.gameObject.GetComponents lt Component gt ()) Disable clicking on graphics if (c is Graphic) ((Graphic)c).raycastTarget false Remove components we don't want if ( !(c is Image) amp amp !(c is TextMeshProUGUI) amp amp !(c is RectTransform) amp amp !(c is CanvasRenderer) ) try DestroyImmediate(c) catch NoOp else allowedComponents componentCount rt.gameObject.GetComponents lt Component gt ().Length Recursive call to children foreach (RectTransform childRT in rt) StripFunctionality(childRT) So the way this code generated the last three lines of the debug log above is the following It took as input a GameObject with two components Button and PopupOpener. PopupOpener requies that a Button component is present in the same GameObject with RequireComponent(typeof(Button)) public class PopupOpener MonoBehaviour ... The first iteration of the while loop (denoted by the text "ITERATION ON Button Invite(clone)") attempted to delete the Button first, but couldn't as it is depended on by the PopupOpener component. this threw an error. Then it attempted to delete the PopupOpener component, which it did, since it is not depended on by anything else. In the next iteration (Denoted by the second text "ITERATION ON Button Invite(clone)"), it attempted to delete the remaining Button component, which it now could do, since PopupOpener was deleted in the first iteration (after the error). So my question is whether it is possible to check ahead of time if a specified component can be removed from its current GameObject, without invoking Destroy() or DestroyImmediate(). Thank you. |

0 | How is this rotation done? There is a video here that shows how the camera rotates around Leon. The camera rotates around Leon in a circle, this is not difficult, but I don't understand the timing logic. Once given a short push, the camera keeps rotating for a few more milliseconds. If the camera would only be rotated during the real mouse movement, the camera would not keep rotating a bit after there is no more mouse movement. However, in this video, the camera rotates a few more milliseconds even after the last mouse movement. How could this be accomplished? Specifically, I would like to ask if somebody can tell me if the developers add some extra movement in the direction of the mouse movement which they then "smooth out", or if they "smooth out" the end of the user's mouse movement. Thank you! |
0 | Unity Mechanim makes physics behave weirdly I'm developing a 2D Wrestling game in Unity 5 build 5.1.2f1. It's just the beginning so the character only has a number of animation states and a rigidbody2d. This is the state machine and these are the Animator and Rigidbody2D components Note that I'm using Root motion to animate "High Knee" state since I've animated the character jumping in the air(high knee) by animating character's transform. This is the simplest form of code to move the character void Start () rb GetComponent lt Rigidbody2D gt () anim GetComponent lt Animator gt () void Update () print (rb.velocity) if(Input.GetAxis("Horizontal") gt 0) rb.AddForce(new Vector2(0,50)) anim.SetBool("isWalking",true) else if(Input.GetAxis("Horizontal") lt 0) rb.AddForce(new Vector2(0, 50)) anim.SetBool("isWalking",true) else if(Input.GetAxis("Vertical") gt 0) rb.AddForce(new Vector2(50,0)) anim.SetBool("isWalking",true) else if(Input.GetAxis("Vertical") lt 0) rb.AddForce(new Vector2( 50,0)) anim.SetBool("isWalking",true) The Character starts moving in x direction with a constant speed as soon as i press the horizontal keys. But for the y axis, when i press up or down key, character starts at 0 and speeds up really really fast( like 50 milisecs) and then the speed keeps increasing and increasing until i release the key. It still keeps moving but the speed doesn't increase anymore. I'm not sure but i think the former behavior is weird and latter is fine (or vice versa). When i remove all the "anim.SetBool" lines in the above code, speed becomes constant for the y axis too, that is, it starts behaving exactly like the x axis. But when i disable the Animator component, x axis movement starts behaving like y axis, that is, speed starts at 0 and quickly increases and keeps increases as long as the key is held down. When i uncheck the "Apply Root Motion" check box, character doesn't move at all. I don't know what's happening. Any help would be appreciated. |
0 | How to make sure an object NEVER passes through an edge collider (2D)? In my top down perspective game, I have a ball that bounces off of walls. The ball should behave in a way where it will always bounce off in a 90 degree angle. The ball can only move up, down, left and right and the walls are slanted so that they should always (theoretically) bounce a ball up, down, left or right. On the ball object, I have a small circle collider 2D and a Rigidbody 2D attached, the walls have a single edge collider 2D attached. Approximately one time out of twelve times, the ball will simply pass through the edge collider, so it's not consistent. How can I make sure that the ball always registers the collision? Here's my setup The script I use to move the ball void Update () switch (direction) case 'u' transform.Translate(0f, ballSpeed Time.deltaTime, 0f) break case 'd' transform.Translate(0f, ballSpeed 1 Time.deltaTime, 0f) break case 'l' transform.Translate(ballSpeed 1 Time.deltaTime, 0f, 0f) break case 'r' transform.Translate(ballSpeed Time.deltaTime, 0f, 0f) break Additional info every wall is it's own object with it's own edge collider. the ball always hits the center of the wall because I center the ball object using the center of the wall it touches. Note I had issues with the ball passing through walls even before I implemented the centering. |
0 | Shooting weapons Unity I'm trying to create a falling word game like z type (code here). Once the game starts a few words are displayed on the screen. When the user types a letter and if that matches with the first letter of any of the words displayed, an "activeWord" tag is added to the word. I have also created a laser script that checks if the tag is active and when that happens, it shoots the laser. What's happening right now is that the laser is shot only once i.e when the first letter matches but doesn't shoot a laser when the remaining words are typed. Can someone please have a look at the code and tell me where I'm making a mistake. this is the word display script where the active word is assigned public void RemoveLetter() remove the first letter if its correct and so on for the remaining letters. change the color of the word to red and add the "activeddWord" tag. text.text text.text.Remove(0, 1) text.color Color.red text.gameObject.tag "activeWord" public void RemoveWord() Destroy(gameObject) removes the word from display here is the input manager script public class WordInput MonoBehaviour public WordManager wordManager void Update () foreach (char letter in Input.inputString) wordManager.TypeLetter(letter) EDIT This is the player script where the laser is instantiated public class Player MonoBehaviour public GameObject laserPrefab void Start () transform.position new Vector3(0.0f, 3.92f, 0) player position void Update () Instantiate(laserPrefab, transform.position, Quaternion.identity) This is the updated laser script public class Laser MonoBehaviour public float speed 10.0f private Vector3 laserTarget private void Start() GameObject activeWord GameObject.FindGameObjectWithTag("activeWord") if (activeWord ! null amp amp activeWord.GetComponent lt Text gt ().text.Length gt 0) laserTarget activeWord.transform.position find position of word transform.Translate(laserTarget speed Time.deltaTime) for (int i 0 i lt Input.inputString.Length i ) Debug.Log("Character from input string " Input.inputString i " n" "Character from word displayed " activeWord.GetComponent lt Text gt ().text 0 ) if (Input.inputString i activeWord.GetComponent lt Text gt ().text 0 ) laserTarget activeWord.transform.position find position of word transform.Translate(laserTarget speed Time.deltaTime) shoot the laser After I do this, there are two major errors that I get As soon as I hit play, the laser fires continuously without stopping. The laser still shoots only once after the word is typed...This is the message I get in the console (screenshot attached). There is a difference of one word between the input string and whats displayed on the screen...Can someone please tell me how to rectify these..... |

0 | How can I spawn an object where I clicked in a 3D space, but spawn it in a 2D location? I have a game where I have an object sat on a 3D plane and I want to click above it to drop an object. Wherever I click I want the object to drop where I clicked on the Z axis, but on a fixed position on the X and Y axis. Please see the below image I am using the following code to do that, which I have attached to my long cube (the platform). using System.Collections using System.Collections.Generic using UnityEngine public class clickBehaviour MonoBehaviour public GameObject GameCube Ray ray RaycastHit hit Update is called once per frame void Update() ray Camera.main.ScreenPointToRay(Input.mousePosition) if (Physics.Raycast(ray, out hit)) if (Input.GetButtonDown("Fire1")) GameObject obj Instantiate(GameCube, new Vector3( 75, 9, hit.point.z), Quaternion.identity) as GameObject Debug.Log(hit.point) GameCube refers to the GameObject of the smaller cube on top of the platform. What seems to be happening, is that when the user clicks a block appears. If the mouse is low down the screen on click then it appears where it should be. If it is higher up the screen it appears off in one direction away from where it should be. I believe this is because Unity is picking up the click way in the background, but I'm dropping the new cube in the foreground. Because of this the Z coordinate is then quite a way off. The further in the background I click the further off it is. How can I have the cubes always appear in the correct position, above the platform? I'm guessing this is a common requirement, but struggling to work out how to do it, or what to Google to find out more info. Thanks |

0 | Cannot implicitly convert type 'T' to 'UnityEngine.Vector3' I'm trying to use C generics on a method in order to send a Vector3 (position) as a parameter. I can print the value correctly but can't store it on a local variable. I also can't access its x, y or z attributes separately. I'm implementing a state machine. My intention is to use generics for allowing sending different parameters to the different states. The value will be sent to an "Enter" method which will be called once on each state every time that state is set to active or current. So for example the player will be on the DefaultState something happens change state to HeroTeleportingState while sending it it's new position This is my Enter method on the HeroTeleportingState class void IState.Enter lt T gt (T newPosition) The following line prints the correct value Debug.Log("move this hero to " newPosition) The following lines don't work pos newPosition pos.x newPosition.x The method call is just something like currentlyRunningState.Enter(Vector3.one) pos newPosition gives me the following error on Visual studio (I'm paraphrasing cause my visual studio is in spanish) Cannot implicitly convert type 'T' to 'UnityEngine.Vector3' And pos.x newPosition.x gives me something like 'T' does not contain a definition for 'x' and no extension method 'x' accepting a first argument of type 'T' could be found EDIT IState interface public interface IState void Enter lt T gt (T value) void Execute() void Exit() |

0 | Which is the better way to distribute server workload for MMO server? I'm making a server for MMO in Unity, which implies that I'll have a big world, split into maps which will be on different servers (to distribute the workload), managed by one master server. Now I can't decide weather I should use one executable per map and have few executables run on each server or have few maps on one executable, which will have it's own server. Second solution also would allow me to redistribute the workload by moving maps from one server to other (which shouldn't take long to do since servers don't need to load models). Btw servers need to be made in Unity for the physics simulation and collisions... The networking part can easily be multithreaded simply by using many threads to process the requests and generate response. But since Unity is single threaded adding more maps would slow down the physics engine (plus the same thread has to apply all actions of the players to the game), so the first solution helps here by using multiple executables. (Edit Note physics engine will take considerable amount of CPU time, even while the scene is empty) Which solution should I chose? EDIT On the end I decided to use both few executables on each server, with each executable being able to run multiple maps and being able to dynamically create dungeons when needed. |

0 | Unity C order of execution for multiple start functions? I have a scene in my project where a lot objects need to access different objects to share data with. Some objects have functions that need to be executed only once during the void Start function. These call a predefined function in a different class. So now you know a bit what is happening I am experiencing an issue. During the Start function they call a method that only works when the Start function of that class has already been progressed. Example Class A has certain values to calculate and set. Once this has happened function A will work. Class B, C and D have a function B that is called at the last line of the Start function. Function B does some magic and then calls function A from Class A. The problem here is however that the void Start from class B, C and D executes before the Start from Class A. This results in not all values being set properly. I only discovered this through debugging and tracking timings of when each function was executed. Is it possible for Class A to make the void Start execute before the void Start from the other classes? For example is the order of execution based on alphabetical values or something awake (per class) start (class A) start (class B) update (per class)? So that start A would happen before start B with a simple change of class name? If I put this code in the awake call I will have the same issues since the awake in other classes might happen before or after the current awake will be executed.

0 | Normal mapping for Android and iOS I'm making a mobile game for Android and iOS on Unity. At the moment I am researching and designing the technical aspects of the game. Since it is not plausible to use highly detailed models for mobile platforms, should normal mapped models be used instead? Thus I have couple of questions about normal mapping. Are normal mapped models much more costly to make, in other words, do they take a lot longer to create? And are they much more expensive to render? At least there are no additional draw calls, but of course the shader is more complex. |
0 | Unity Set LightProbes to "Off" on Static objects Since I use Light Probes for Indoor Scenes only I only need them to work on Dynamic Objects. Objects in Indoor Scenes are all Lightmap Static and baked, objects in outdoor scenes rely on real time lighting. Most objects are not within range but sometimes the Lightprobes from inside interfere with Static objects outside and add light to them that should not be. It's really time consuming to disable LightProbes in every individual Mesh Renderer I sort all Prefabs amp Game Objects by Static, LightmapStatic and Dynamic. Turning Lightmapping on and off can be easily done in the hiearchy but turning off LightProbes needs to be done in every individual Mesh Renderer. Is that so, or am I overlooking something? If not this is really something that should get fixed. My Version is 2017.3.1f1 |
0 | How to achieve 2D ski movements similar to Alto Adventure? I'm trying to achieve 2d movement similar to Alto's Adventure with Unity 2D. When grounded I want the character to slide alone the terrain parallel to the slope, but I want to be able to freely rotate the character in mid air. In my current failed implementation I tried using a 2d collider attached to an gameobject with a movement custom script. I'm using vertical and horizotal raycast to detect the slopes, and the object rotates based on the angle of the slope. Long story short I've given up on this implementation for now. Do you guys have any suggestions or pointers on achieving this type of movement? |

0 | Hierachy organisational methodology in Unity I'm just getting into Unity, so I do not know if my system of organisation will have any negative consequences. I intend to store my project files and assets under an assets directory, then into scripts and such, as is commonplace. For the hierarchy I intend to have a top level empty object titled something like "Hierarchy", under which all objects will be children. I am also thinking that I will further subdivide into logical and physical objects, putting objects that do not have components on them but have a physical space in the game (not including transforms) under the former, and anything with a physical presence under the latter (lights, player etc). The main reason is so that I know where to look, based on functionality. I can also use alt click to close all objects at once. I find this helpful for navigating the hierarchy. Is this a bad plan? |

0 | LOD culled gameobject still interacts with raycast The camera is sort of top down and the player can move objects around, rotate them, delete them etc. I use a raycast to check what was hit when the player clicks. But some objects are culled by the LOD group when far away, but the LOD group only disables the renderer, not the colliders, so it still interacts with the raycast. This means a player can move or delete an object that they can't even see. I've tried looping through all the renderers in the lod group and using renderer.isVisible but it doesn't solve the problem of collision and raycasts. I'd really rather not poll isCulled every frame in update either because there are thousands of gameobjects, that would be horrible for performance.

0 | Any way to combine instantiated sprite renderers into one texture so I can apply into a plane at runtime? So I am procedurally generating a tile set in Unity by instantiating different tiles that only have a transform and sprite renderer components. I managed to pack the sprites using unity sprite packer assigning them a packing tag so that I reduce the draw calls drastically. But Im still having to deal with a great amount of game objects in the scene when the camera zooms out, increasing the batching and giving me problems when I try to apply light to them for example. So I am trying to find a way to combine all these sprite renderers into a texture.So I can then apply this to a plane and Ill only have to deal with one plane gameObject for the map. But I cant figure out how to do this. I cant really use the combine meshes way as they are sprites only, not meshes. I tried taking a screenshot at run time but It comes up a bit blurry. Any idea how can accomplish this? Thank you for your help. |

0 | How should I load change activate scenes? Scenes are confusing the hell out of me and I'm pretty sure they should be simple to understand. When the game loads, only the current scene has a buildIndex ! 1. In order give it a 'real' build index I need to load it by path or name (because there's no build index). The scenes are ten game scenes, one title scene and one persistent scene (which has the player and the status bar with the score etc.). Should I load a scene every time I change scene and then load additive afterwards or should I be using Set Active Scene? All the scenes are ticked in the Build Settings. I'm looking at the index with this private void Start() var sceneName "Persistent" var sceneBeforeLoading SceneManager.GetSceneByName(sceneName) Debug.Log( "Scene sceneBeforeLoading.name , BI sceneBeforeLoading.buildIndex ") SceneManager.LoadScene(sceneName) var sceneAfterLoading SceneManager.GetSceneByName(sceneName) Debug.Log( "Scene sceneAfterLoading.name , BI sceneBeforeLoading.buildIndex ") Which outputs Scene , BI 1 UnityEngine.Debug Log(Object) Title Start() (at Assets Scripts Title.cs 10) Scene Persistent, BI 1 UnityEngine.Debug Log(Object) Title Start() (at Assets Scripts Title.cs 13) |

0 | Unity3d change texture on terrain at specific vector3 at runtime I need the terrain texture to change at certain positions depending on where trees etc. are randomly positioned at runtime. I'm struggling to find any solid information about how to take a particular vector3 and tell the terrain to paint a different texture of size x at that location. So far I have found a lot of information about how to change textures based on height map information. As my map is flat, that information doesn't seem very relevant. EDIT using the following code when each tree was randomly instantiated public void ChangeTextureAtTreeLocation(Vector3 treePosition) int mapX (int)(((treePosition.x terrainPos.x) terrainData.size.x) terrainData.alphamapWidth) int mapZ (int)(((treePosition.z terrainPos.z) terrainData.size.z) terrainData.alphamapHeight) float ,, splatmapData terrainData.GetAlphamaps(1, 1, 4, 4) terrainData.SetAlphamaps( mapX, mapZ, splatmapData) terrain.Flush() got me this result As you can tell, the results aren't great. There are two main deficiencies I don't know how to access the terrain texture array directly so I paint a portion of the map first (see the bottom left of the image), sample that portion, and then set that sample at the location of the trees. This is not ideal as I cannot change the shape, size, or opacity of the added terrain texture. There is also no blending between textures, which gives the texture a rabbit burrow look. you cannot see it in the image, but the textures do not appear under the trees but are directly north east of them. Not sure why that is. I'm assuming it has something to do with how textures are drawn relative to their origin. |
0 | How to drag an object with mouse with collision? I want to drag a GameObject with the mouse but I need collision. The basic mouse dragging code simply sets the position of the object to the hit.point with an offset from the difference at the start of the drag. As for collision, I've tried using kinematic rigidbodies and setting the position with rigidbody.MovePosition(uh) but that allows the object to rotate while pushing it up against a corner on one side. With rotation constraints enabled, it flickers a lot and still intersects a lot. I also tried playing with collision detection and interpolation. None of the settings improved it. I also tried Physics.ComputePenetration but that is extremely messy because some of the objects I'm dragging, have several colliders. The distance it calculates is per collider so it doesn't calculate the offset required to separate the entire object. I tried disabling all the colliders and then adding a single box collider sized to fit the bounds of the object. That had bad flickering problems. The last thing I tried was box casts on each side that would find the closest point and offset the mesh in that direction. But if I moved the mouse too fast it would go inside the other mesh and would no longer register any colliders intersecting the box casts. It also suffered from flickering problems. Ideally, I want to have fairly accurate detection. I don't want to approximate the other colliders (not the ones on the object I'm dragging). Assume the other colliders could be any type (box capsule sphere mesh). The image below shows the problem I'm having. The green dot shows approximately where the cursor was (also the hit.point from the raycast on the surface of the red cube). What I expect is that the couch should be offset so that it was close to the cursor but prioritizes not intersecting other meshes over sticking to the mouse. |
0 | Coloring a Voronoi Graph Intro I want to convert a Voronoi Graph made with this awesome library by jceipek on GitHub into something I can work on. So far so good, this user provides with a demo to start with and shows how to generate the VG. Question How do I convert the VG (made by edges and that dot in the middle) into something that I can work with? Such as, after you generate some noise and apply to it (height), you colour the polygons based on it. Thoughts Something comes to my mind about instantiating meshes and tiles based on the edges and the position of the dot as a start, but it won't work if I can't "detect" the polygon. Expected result Image from this blog about Voronoi Mapping link What I have It is drawn with Gizmos (for visual debugging in Unity) I want to know how to color my polygons as in the expected image above. So I thought about doing a mesh or individual tile (and color it based on height afterwards but that is sauce for another question if needed) Edit of my progress To further explain this question I provide the next image. The image shows that I could use that position data somehow and turn that random polygon shape into a "tile" that will have a colour (mesh?) and possible data in it (script). I hope this helps otherwise let me know in the comments. |

0 | What am I suppose to use instead of Unity Resources if I have to load and unload sprites at runtime? I recently read this guide posted in the Unity website about Resources. It is clear from the get go that it is discouraged to use Resources unless you are prototyping something. My game is like a 2D RPG, and it has over five thousand monster sprites (yes, a lot). As far as I'm concerned, it makes perfect sense to put all the sprites in the Resources folder, and just load the ones that I need (using their name) when a battle starts and then unload them. The Unity article makes one point that might support my approach Generally required throughout a project's lifetime Well, I'm not so sure about it in a single game session it's entirely possible that thousands of those sprites will not be used at all as the player simply doesn't encounter those monsters. The article goes on to talk about why is it discouraged to use Resources This operation is unskippable and occurs at application startup time while the initial non interactive splash screen is displayed. Initializing a Resources system containing 10,000 assets has been observed to consume multiple seconds on low end mobile devices, even though most of the Objects contained in Resources folders are rarely actually needed to load into an application's first scene. And it is indeed true my game does in fact take several seconds to load on some low end devices, especially Android ones. It is also true that none of those sprites of mine need to be loaded at startup. So I am willing to stop using Resources but I am at a loss now the article doesn't mention a reasonable alternative to this. Here are the (unreasonable) approaches that I have thought of Create a component with a collection of all the sprites, that way they are all loaded without using Resources. Yeah but I have five thousand sprites. This sounds extremely tedious. Same as the previous suggestion, but use Texture Packer or something similar to pack lots of sprites into different sheets this way I have to do less work. My sprites are large and packing them won't be a huge help I'd still end up with a thousand or so sheets. My point is, I just can't have 5000 sprites preloaded. I need to load them at runtime via Resources, but Unity clearly discourages it. Is there a solution to this? |
0 | How do I properly change the value of a prefab'd instance variable? I am currently following a tutorial on how to make a 2D platformer in Unity. The tutorial explains how to make an enemy wave spawner, but it doesn't explain how to make enemies stronger after I have completed a certain amount of waves. So, to explain I have an Enemy class, which has an EnemyStats class in it public class Enemy MonoBehaviour System.Serializable public class EnemyStats public int damage 20 public int maxHealth 100 public int CurrentHealth get return currentHealth set currentHealth Mathf.Clamp(value, 0, maxHealth) private int currentHealth public void Init() CurrentHealth maxHealth public EnemyStats stats new EnemyStats() private StatusIndicator statusIndicator void Awake() stats.Init() statusIndicator transform.Find("StatusIndicator").GetComponent lt StatusIndicator gt () if (statusIndicator ! null) statusIndicator.SetHealth(stats.CurrentHealth, stats.maxHealth) And in the WaveSpawner class I have the method to spawn the enemy private void SpawnEnemy(Enemy enemy) Transform sp spawnPoints UnityEngine.Random.Range(0, spawnPoints.Length) if (CurrentWave 5 0) enemy.stats.maxHealth 20 Instantiate(enemy.transform, sp.position, sp.rotation) In the WaveSpawner you can set a certain number of waves (let's say 5), and after you complete all of the waves I've set them to repeat. So after I beat the 5 waves, I want the 5 waves to repeat and the enemies to be stronger (for example to have their max hp increased by 20). I do that with the line enemy.stats.maxHealth 20 But the problem here is that after this line is executed and I Instantiate the enemy prefab, the prefab changes its value in the inspector. So let's say that the initial value of the prefab was 120, after I beat the 5 enemy waves, the value of the prefab is set to 140. Then, after I reset the game, the initial value of the prefab is 140 and the max health of the first enemies is 140 and not 120. I have tried to not change the maxHealth variable of the EnemyStats class, but instead to have another variable tempMaxHealth and do the changes on it. This doesn't resolve my problem, as other problems arise and I don't know what to do anymore. I hope that you have an answer for me, I would be grateful if that's the case. |

0 | C Events in Unity to separate GameObject features into Components Broadly speaking, this is a question about how to separate my game object's code into distinct feature components that can be added and removed as needed. More specifically, I am trying to achieve this using C events in Unity. But I am open to other solutions. Scenario We have enemies that have health. When their health reaches zero, they die. Some enemies (think asteroids) may spawn a number of child enemies (think smaller astroid pieces) when they die. Others however, just die. I want to have two scripts EnemyHealth Tracks the enemy's health and kills the enemy when its health reaches zero. EnemyChildrenSpawner Spawns child enemies after the enemy's death This way, all enemies will have the EnemyHealth script, and some enemies will have the EnemyChildrenSpawner script in addition. My idea is to have the EnemyHealth script raise an event when the enemy dies, and have EnemyChildrenSpawner subscribe to said event to spawn the children. What would be the best way of achieving this? Here's my attempt. It works. Just not sure if this is good practice, especially using the GetComponent in the second script? EnemyHealth.cs public class EnemyHealth MonoBehaviour The event to invoke when this enemy died public event EventHandler OnDied Gets called when this enemy's health reached zero private void Die() Invoke the died event OnDied?.Invoke(this, EventArgs.Empty) Destroy this enemy EnemyChildrenSpawner.cs public class EnemyChildrenSpawner MonoBehaviour private void OnEnable() GetComponent lt EnemyHealth gt ().OnDied SpawnChildren private void OnDisable() GetComponent lt EnemyHealth gt ().OnDied SpawnChildren private void SpawnChildren(object sender, EventArgs e) Spawn children |

0 | 2d ParticleSystem batching problem I have multiple ParticleSystems with TextureSheetAnimation pointing to the same texture, using different offsets rows to choose different textures. They seem to batch with each other, but they're also being split by Unity into multiple batches in a strange manner. Here's a Frame Debugger view These 4 Draw Dynamic are on the same atlas, using Mobile ParticlesAdditive shader. The reason of breaking batching is Objects have different batching keys. This is usually caused by using different vertex streams on ParticleSystems or by mixing Lines and Trails, or by mixing lit and unlit geometry. All of the ParticleSystems have a simple setup, some Color Over Lifetime, some Velocity Over Lifetime etc. The strange thing is that Unity breaks batching like it makes one batch, puts half of the stars and half of the smokes into that, and then, makes another batch from these two. So they do batch, and the don't o.O I couldn't find and help on the web about this issue. I'd be glad for help. |

It teleports to nonsense locations like player is looking at x but it teleports to x. Anybody have solution for this? Since it is not rigged, root motion is not working.

Idle is stable as a position, but attack animation is changing position in canvas for example animation canvas is 1920x1080 canvas size and animation starts from the left size to right size. I can't move the character with a script because it has its own timing that I can't set up with script. So I am trying to get the last frame position and pass it to idle animation at that position but instead of that without code it teleports back to the initial position after attack is completed.

Is there a way to limit the particles in a sensible way? |
0 | Unity Deactivating Keyboard Input Interpolation I'm working on a game in Unity, and it is a little jarring to use with keyboard controls. I'm using the built in Input Manager, where I have a set of axes mapped to the left and right keys. When the player is using the keyboard instead of a joystick, I'd like it to simply be 1 when hitting left, 1 when hitting right, and 0 otherwise, but this isn't the case. I've found that for the first few frames of the button being held, Unity automatically builds up to the value for example, if I'm holding right, the value wouldn't go straight from 0 to 1, but rather from 0, to 0.25, to 0.5 and so on, continuously up to 1. Can I deactivate this? If so, how? Thanks in advance. |

0 | How to make a one way trigger? In my game, there is a cat that jumps on pillars. When it lands on a pillar, force is applied and it jumps. There are three animation states which are just single image. The states are idle,up and down. When cat lands on the pillar, Collision is triggered where i set animation state to idle. Then, force is added and animation state is changed to up. But problem is, this collision and add force happens so fast, the cat switches between down and up without showing idle. To overcome this, i added an empty child object to pillar. Then added Edge collider set as trigger. This child was placed slightly above the pillar. So when cat hit this, animation state would switch to idle. Then the cat would land on pillar and jump. This worked except, the trigger is two way. When cat jumps from pillar, it collides with this trigger and state is changed from up to idle. I tried to add platform effector with one way, but the effector cannot be used on a trigger. So, is there a way i can add a collider to the empty child which will let it go through aftyer setting state to idle? |

0 | Retrieve the original prefab from a game object How would one proceed to retrieve the original prefab used for instantiating an object? In the editor these two functions work Debug.Log(PrefabUtility.GetPrefabParent(gameObject)) Debug.Log(PrefabUtility.GetPrefabObject(gameObject)) But I need something that works in the release version. I have objects that can be transported between scenes ands I need to save their data and original prefab to be able to instantiate them outside of the scene they have been originally instantiated. ie Game designers create new prefabs. Game designers create objects from prefabs and place them in scenes (50 to 150 scenes). Game is played and objects are moved across scenes. Game is saved and infos about objects which have moved are saved in the save streams (files or network). This is where I got stuck. Currently, to palliate to the shortcomings, we're saving the name of the prefab in the prefab. But each time a prefab is moved, renamed or duplicated the string must be changed too, sometimes the objects created from the prefab keep the original name (game designer might have edited the prefabPath field). Maybe there is a better way to achieve proper save games without having to access to the original prefab name. But currently we keep the saves segmented on a per level basis (easier and safer to save load to files and transfer the save games to from servers) |

0 | How to make an expanding radial search in Unity? I am currently working on a City Builder Game and I often come across the problem of having to decide wich location to use. Examples The citizen has a job and needs a home. There are several buildings with open slots. The citizen is at a positon and is hungry. There are several restaurants on the map. How can I choose the right building to go to? I don't really wan't to check the distance for each, because there could potentially be hundreds of buildings and that decision problem occurs quite often. I also don't care for the optimal solution, any nearby result is fine. Currently all buildings register them self in a LinkedList. When searching for something I'd start at the beginning and the first occurrence that was 'good enough' would be returned. Citizen now drive across the map for something that was right next to them if the one far away was built earlier in the game. Any suggestions? |
0 | Why is Raycast hitting masked layer? Many questions have been posted on this topic but I'm facing a weird behavior which I could not find an explaination for. I perform a raycast giving it a LayerMask parameter which is defined as public variable and set in the inspector with thick on layer "Wall" and "Enemy". At first glance it appeared to work fine because raycast rightly stops on GameObjects with that layer. But then I saw that it stopped also on GameObjects with default layer, like if the LayerMask was ignored. Is there something I'm missing? According to this answer I set up everything correctly and I expected it to work fine. Looking at the inspector at Runtime I can clearly see that my mask is set only to "Wall" and "Enemy", and that the GameObject the collider is attached to has default layer set. I'm then stating that the mask the way I'm using it does not exclude other layers. The only way I found to have this working is by setting that GameObject layer to Ignore Raycast but in this case the LayerMask is not necessary. I'm calling the function this way RaycastHit2D inSight Physics2D.Raycast(start, end, lm) Maybe is there something different using Physics2D? I would really enjoy touse LayerMasks instead of giving specifically Ignore Raycast to whatever I want to ignore. Any clue? |
0 | How to use the latest MongoDB C driver with Unity? I recently updated my Unity 2018 to the 2020 version then I created a new project to connect my game to a MongoDB database. My main goal is to be able to store not only common data in my collection but also files and images by using GridFS. I use Visual Studio 2019 Community so for my project. I installed the MongoDB drivers directly from NuGet. In Visual Studio everything is OK, I added a using for all required libraries and I have no errors but when I switch to Unity 2020 it seems that I can't start my project because my MongoDB driver is not correctly loaded there. I found some tutorials like this one where they had the same problem and fixing it by adding the DLLs directly in the Unity folders. That works for me, but only with the DLLs shared in the tutorial (you can access the working DLLs in the video description). What is a bit disturbing is that the DLLs' versions seem to be outdated, since the connections process is a bit different from the one in the MongoDB documentation. I cloned the latest MongoDB C driver repository from GitHub and tried to reproduce the same process with the latest DLLs, but once again it only works in VS 2019 but not in Unity, even though I have added the DLLs in the Unity folder. Is there is some kind of compatibility problem between Unity and the latest MongoDB? How can I fix this to work with the latest version? |

0 | Storing wins and losses locally in Unity I am writing here as I have made a game in Unity where I want to store how many wins losses a player has. The way I am thinking to do it is by putting 2 counters One for every time a player wins, and one for every time a player loses. What I do when a player wins or loses is that he can shoot something and restart the game I load scene 0 here. I know that the counters will reset once the player closes the application, but that doesn't matter. Anyway, is there a better way to do it? The other thing I am thinking about is storing how many times a player has played the game in total, and this has to be stores locally too and must not get reset when the player closes the application.

0 | Unity augmented reality app doesn't work on android I am pretty new to unity and augmented reality applications. I use unity 2019.4.4f1 and my project is very simple as you can see in the screenshot below I am using Wikitude plugin for image tracking and the image i am using as the marker is the Jack of Clubs card as you can see in the assets. The project works fine when i press play and use my laptop's webcam , but when i build the project for android (unity 2019 automatically uses Gradle to build the project) and install the .apk file in my android phone, all i see on my phone screen when i open the application is As you can see the phone camera doesn't work and it gets stuck in this screen. How should i fix it? Does it have to do something with Gradle? I haven't tried using unity version 2018 to build it using the quot Internal quot build option. Anyways that's just my own thought and i might be wrong, but the final question remains which is how this problem can be fixed? By the way i don't build the .apk file directly from the unity engine. I use the export option in unity to get a gradle project folder then i use that in Android Studio to build the final .apk file. The reason that i don't use unity to build .apk is that it gives errors and doesn't work for me so this is the solution i found for it.

0 | Navigate UI with Dpad from Xbox controller on Mac Unity ? So, according to some documentation I found, the Xbox controller on Mac does not return Dpad presses as vertical horizontal axes As you can see, the Dpad is only recognized as buttons 5, 6, 7, and 8, and not as horizontal vertical axes. For my character's movement, I just created code that returns 1 or 1 for axis depending on the button pressed. It works perfectly fine. But then I found another problem UI navigation. I can't navigate my menus with the Dpad on Mac because the the EventSystem is expecting navigation via horizontal vertical axes, which the Dpad is not providing.

0 | Unity how to render to texture with VR distortion I've also asked the question here http answers.unity3d.com questions 1392099 how to set a render to texture camera to be a vr c.html (but it's currently "under moderation") So, I want to do some post processing effects in VR. I put a camera as a child of the Main Camera and set it to render to texture. Then, I take what is rendered, and display it (with my post proc shader) on a quad in front of the Main Camera (The main camera and the child camera render different layers, so I don't render the same thing twice). (Also worth noting I know that the depth will be collapsed out of the rendered to texture content this is intentional.) The problem is, in this process, the positional data (that was rendered to texture) gets misaligned. I've already fixed a problem where I have to manually set camera project.GetComponent lt Camera gt ().aspect main camera.GetComponent lt Camera gt ().aspect every frame. (Changing setting the screen size auto sets the aspect ratio of the main camera it does not automatically set the aspect ratio of the child camera. So, with just that, everything lines up great and looks fine when it isn't in VR. But, when it is in VR, it appears that maybe some distortion is happening to the main camera that isn't happening to the render to texture camera, and thus, the overlay (the post proc'd content) isn't lining up. So what can I do to emulate the VR distortion in the child camera? Are there other properties of the Main Camera that are getting auto set in VR that I can manually copy to the Main Camera? (I also noticed that aspect wasn't listed in the camera documentation https docs.unity3d.com Manual class Camera.html unless you knew to search for it explicitly, so I think it might be likely there is some other property I'm missing?) |
0 | Top Down Octree Generation of Procedural Terrain I'm trying to implement a voxel based terrain generation system in Unity3d (C ). I have successfully implemented a uniform 3d grid system, and have extracted the isosurface out using Marching Cubes and Surface Nets algorithms. I quickly bumped up against the inherent issues in representing all space with a 3d grid. Much of this space was either above or below the surface, and I turned to space partitioning with octrees, as it didn't seem too difficult. One of the great things about octrees is that octree nodes that that don't have edges intersected by the surface don't need to be split again. I researched, and found a couple resources to construct my code. One is Volume GFX, and another is the original Dual Contouring paper by Ju et al. My edge checking is done by the Marching Cube's checking from Paul Bourke's code. If the "cubeindex" is either 0 or 255, then no edge is intersected, and the octree node does not need to be split. My Octree generation code works for something like a quarter sphere, where the surface features are extremely normal As seen in the picture, only octree nodes containing the surface are subdivided. Working great. Now, however, when we move to something more complex, like Unity3d's PerlinNoise function GASP! What's that hole doing in the mesh at the lower right corner? Upon closer inspection, we see the octree didn't subdivide properly (red lines highlighting the offending node's dimensions) This turns out to be the same issue Jules Bloomenthal highlights in her paper on polygonization, page 10, Figure 10. Traditional methods at generating top down octrees ("Adaptive Subdivision"), are sensitive to fine surface features relative to the size of the octree node. The gist X X lt Node X X X's tested values, all outside of the surface! lt surface The surface breaks the surface, but comes back down before it goes over a vertex. Because we calculate edge intersections by looking at the signs at the two vertices, this does not flag the edge as crossed. Is there any method to determine if these anomalies exist? Preferably, the solution would work for more than just the Unity3d noise function, but for any 3d noise function (for cliffs overhangs floating islands, etc). UPDATE Thanks to Jason's awesome answer, I was able to answer my own questions I asked (in the comments under his answer). The issue I had was that I didn't understand how I could create a bounding function for trigonometric functions (sine,cosine,etc) due to their periodic nature. For these guys, the periodicity is the key to bounds functions. We know that sin cos reach their extrema values at a set interval, specifically every 2. So, if the interval we are checking contains any multiple (cos) or half multiple (sin) than 1 1 is the certain extrema. If it doesnt contain a multiple (i.e. the interval 0.1,0.2 ), then the range is simply the values of the function evaluated at its endpoints. UPDATE 2 If the above doesn't make sense, check Jason's answer to my comments. |
