0 | 2D Animation based on Time.deltaTime has problems when the game performs long operations I animate my 2D sprite using the Update() method float timer 0.0f float delayPerFrame 0.04f void Update() timer Time.deltaTime if (timer gt delayPerFrame) timer 0 Logic to display the next frame As you can see, it is pretty simple every 0.04 seconds the next frame will be set. But sometimes, my game needs to do some exhausting processing (like loading large scenes and whatnot), which causes a tiny little lag in the game. When this happens, my sprite begins with a wild, fast animation. Then eventually it resumes at a normal pace. I imagine this is because the lag caused the Time.deltaTime value to skyrocket for a period of time. I am also under the impression that Update() is called too often during such period (although that shouldn't matter). I don't want to use existing animation features of Unity. My game is already built under this particular piece of logic, so I'd like to fix it. Using FixedUpdate() doesn't help. I can also confirm that Time.deltaTime does indeed peak at the beginning. Note that this occurs only after doing an exhaustive operation. If you spawn a sprite of these in the middle of the game, everything will go smoothly. But if you spawn them immediately after doing something like loading a large scene, then they will have some sort of boost at the beginning. |
0 | How can I resize a game object using single drag handle? Really need your help. I'm trying to create a custom controller for my app to allow users to resize and rotate game objects using a single drag object. I was able to create the code to create the visuals and to rotate it but I'm stuck on how to resize the game object. To position the drag handle at the start, I'm getting the bounds of the target object and taking the bounds.extents.magnitude to determine the y position. So I was hoping the behavior would be such that when you drag the handle closer to the center of the target object it shrinks the bounds.extents.magnitude based on the new handle position and then becomes bigger if you go further away from the center of the target object. Here is where I am now using System.Collections using System.Collections.Generic using UnityEngine public class CircleMaker MonoBehaviour public float lineWidth .1f private int segments 360 private LineRenderer line private float radius private Renderer boundsSource private Bounds bounds public GameObject dragHandle public GameObject target private int pointCount private Vector3 points public int angle 0 public float zPosition 8.0f public bool isDraggingHandle false void Start() line GetComponent lt LineRenderer gt () boundsSource target.GetComponent lt Renderer gt () bounds boundsSource.bounds line.useWorldSpace true line.startWidth lineWidth line.endWidth lineWidth line.positionCount segments 1 line.receiveShadows false line.shadowCastingMode UnityEngine.Rendering.ShadowCastingMode.Off pointCount segments 1 points new Vector3 pointCount float r bounds.extents.magnitude float d2r Mathf.Deg2Rad (target.transform.localEulerAngles.x 360f segments) dragHandle.transform.position new Vector3(Mathf.Sin(d2r) r, Mathf.Cos(d2r) r, zPosition) target.transform.position DrawCircle() void Update() if (isDraggingHandle) rotate object based on drag handle location Vector3 direction target.transform.position dragHandle.transform.position int sign (direction.x gt 0) ? 1 1 float offset (sign gt 0) ? 0 360 float angle Vector2.Angle(Vector2.down, direction) sign offset target.transform.rotation Quaternion.Euler(0, 0, angle) if (target.GetComponent lt DragAndDrop gt ().isDragging true) dragHandle.transform.parent target.transform else dragHandle.transform.parent null DrawCircle() draw circle around target gameobject based on bounds.extents void DrawCircle() radius bounds.extents.magnitude target.transform.localScale.x for (int i 0 i lt pointCount i ) float rad Mathf.Deg2Rad (i 360f segments) points i new Vector3(Mathf.Sin(rad) radius, Mathf.Cos(rad) radius, zPosition) target.transform.position line.SetPositions(points) |
0 | How to Stop TextMeshPro Truncate from Removing Next Line? Unity 2020.3.1f1 In updating from Unity 2019 to 2020, it appears the TextMeshPro (TMP Text) is behaving differently. The code for TMP stayed the same upon updating Unity, so I presume Unity itself must be doing something differently. Nevertheless, I also updated the TMP package and it did not resolve the issue. The Issue I have two lines of text in one text box. I want the overflow to be truncated, but to keep the second line in existence. Example Input This is the really long text on the first line that I want cut but still have this line show. In short, I want it to read as follows when using the quot truncate quot option like it used to work before This is the really long text still have this line show. Instead, the second line disappears and it acts as if I have only that first line (centered vertically). This is the really long text So how do I get this functionality back? Is it possible? |
0 | Text Based Tutorials for Unity3d I hope this is the right place to ask this. I'm very new to Unity but not to programming. I also have some basic game programming experience. I'm searching for text based versions of the videos from unity3d.com learn tutorials. These tutorials are very good, but I end up forwarding videos a lot to get key screenshots and code snippets. Is there any text pdf html .doc .rtf (i'm very open) version or similar resource to learn unity? Again, those tutorials are amazing and I'd hope to find something of similar quality, but I know that if I have to skim through tens of hours of video I'll end up frustrated. I get that the long hard way is probably the most robust one for deeper understanding, but I was hoping to hack a quick project. EDIT If this can make it a relevant question, then I am currently looking at the "Roll a Ball Tutorial". Really, any other text tutorial would be very welcome |
0 | How to stop my particle systems from being frustum culled Please could somebody advise on whether it is possible to control the culling of particle systems in Unity? I am referring to the entire system, not individual particles. In my use case, I am modifying the vertex transformation to get the quot distant object effect quot . When the camera thinks it is not viewing something it will cull it (frustum culling). For most game objects you can get around this by inflating the size of the bounds to make the camera think it is within its frustum and therefore not get culled. However, particle systems are not a single object, they are many particles and I can t see a way of manipulating the total bounds of the system. Any ideas? |
0 | Render object with different shader depending on the camera I have an object with a custom shader. When it is being rendered by cameraA, then I want it to render a particular way (ex red). When it is rendered by another cameraB, I want it to render a different way (ex green). Is there some way I can tell what is the current camera rendering in the shader? Or perhaps I can toggle a boolean value in my shader between rendering of each camera? Where would I do this (OnPostRender() maybe?). |
0 | Should larger Unity Projects use Visual Studio I've worked with several engines and I'm most comfortable with a mature engine, world editor and C codebase. I'm now looking at Unity as a side project and have mostly been working in Javascript. Has anyone done a large scale project with Unity and does it require Visual Studio or is sticking to the Javascript approach best? Are there any big pitfalls with large scale Unity projects or with working with Visual Studio? Most the stuff I've seen has been focused at smaller Indies or people with little experience. I should have phrased this as an external IDE, Visual Studio is just my IDE of choice |

0 | Raycast implementation in order to optimizate collision detection I want to know if a gameobject (a plane) is facing another one to prevent collisions. Right now I have an array that contains all planes in the scene and, for each one, compare position in order to detect if is facing it or not. The number of planes is small, but I want to increase it and this method is a little... Mean. I was thinking to implement a raycast to detect if the gameobject has another one in front of it. Is it worth? Will it be less expensive? I think that raycast it's very expensive. In addition, I think that I will have to run three raycasts for every plane. Obviously this is not executed every frame, but every two seconds. |

0 | How to restrict movement of Leap Motion hand object I have a quot Hand quot GameObject controlled by a Leap Motion Controller. The Hand despite having RigidBody and Box Collider just seemingly moves with no regards to physics (transform translate movement I suppose). So it clips through other Rigidbody objects. I'm trying to pseudo introduce physics to it. I created a second GameObject quot HandClone quot (with Rigidbody and Box Collider) that copies the first Hand position but moves with actual physics. HandClone script private void FixedUpdate() rb.MovePosition(targetTransform.position) rb.MoveRotation(targetTransform.rotation) Now HandClone goes where Hand goes, and HandClone is successfully bumping into other objects. However, when HandClone gets stopped by something, Hand still keeps moving past HandClone and clips into the other objects, like before. Now I am thinking that the way to solve this is to constrict Hand's movements to the bounds of HandClone so that finally Hand will stop clipping through objects. But how can this be achieved, would that even work, and is there a better way? Will movement streamed from Leap Motion Controller even respond to scripts like that? Edit I've now decided to hide Hand and place HandClone where Hand was. But my script for HandClone to copy Hand's movements is making HandClone fly all over the place. Here's the script using System.Collections using System.Collections.Generic using UnityEngine public class clone1 MonoBehaviour private Rigidbody rb public GameObject target void Start() rb this.GetComponent lt Rigidbody gt () Update is called once per frame void Update() private void FixedUpdate() Vector3 newRotation new Vector3(target.transform.eulerAngles.x 8.5f, target.transform.eulerAngles.y 172.78f, target.transform.eulerAngles.z 94.02f) rb.MoveRotation(Quaternion.Euler(newRotation)) The reason why I am adding those float numbers is because when the game isn't playing, those numbers are what make HandClone sit in the correct position, so I thought it would help with alignment in playmode. But HandClone is just flying everywhere regardless. Any advice with making the HandClone stay attached to the avatar's wrist would help. |

0 | Sprite with transparency Create box collider (ignoring transparent area) I have a sprite which has a transparent area in it. The non transparent area is a free form graphic (red). I would like to create a box collider around it (yellow), but ignoring the transparent area. Some notes to the image above Left This is what happens, if I apply a PolygonCollider2D. The yellow line represents the area covered by the PolygonCollider2D. This is not what I want. Middle This is what happens, if I apply a BoxCollider2D. The yellow line represents the area covered by the BoxCollider2D. This is also not what I want, as it includes the transparent area of the sprite. Right This is what I want Have a BoxCollider2D outside my free form graphic. Here's how I currently load my sprite data into the game during runtime My sprites are located in the Assets Resources SceneData ... folder structure of my project. The graphics are stored as .png files. When loading a level, I load the required graphics as sprites like this var sprite Resources.Load lt Sprite gt ("SceneData AfternoonAtTheBeach DragAndDrop Graphics Level1 ElephantWithIceCream") "ElephantWithIceCream" is the .png file (Resource.Load wants me to refer to this file without file extension) After that, I create a new game object and attach a SpriteRenderer component to it. The sprite is assigned to the SpriteRenderer by setting the sprite attribute of the SpriteRenderer component. My first thought on how to solve my problem was to do something like this Create a PolygonCollider2D and try to convert it into a BoxCollider2D. But I was not able to find code examples on how to do this. After that, I thought of trying it to do like this Create a PolygonCollider2D and try to extract some useful information out of it (such as bounds, center, extents, etc...). Delete the PolygonCollider2D and create a BoxCollider2D. Use the previously extracted info to create the BoxCollider2D. But I fail doing so. I am also a bit confused as sometimes they refer to world space or local space. Does anyone have a working recipe for doing something like this? I do not really understand how to work with center, bounds and extents. If there is any better way of doing this, I am highly interested. Thanks a lot for your help! |

The problem is that Unity internally stores rotations as Quaternions and that there can be several euler representations for a single Quaternion, like Euler 123f, 17f, 235f and Euler 57f, 197f, 55f are the same thing. Is there any way I can bring an Euler representation into some kind of normalized form that allows me to reliably check it against my limits? |

0 | Rotate bone on 1 axis to look at another object Unity 3D I'm new to game development and I'm trying to create a basic 3D Tower Defence game as my first project. I've created a basic turret in Blender and I'm now trying to rotate 2 different bones to make the turret follow the enemy. The first bone (which I have working) rotates the turret to face the direction of the enemy. The second which I can't get right needs to rotate the gun at the top of the turret to look down at the enemy. I need it to keep facing the same direction as the rest of the turret and don't want it to tilt to either side. So it needs to move on 1 axis only. I have tried various things, including examples from the Internet but I can't figure it out. So far I've managed to get it to look down at its base, up at the sky and spin like a wheel. Basically everything except where it's supposed to be looking. Here is the code I have at the moment if (enemiesInRange.Count gt 0) Rotate Platform This section works fine Transform platform transform.root.Find("Armature BaseBone PlatformBone") Quaternion targetRotation Final rotation (I.e. facing the enemy) Vector3 turretPosition platform.position Store the turrets current position turretPosition.y 0 0 the Y axis to stop the turret tilting up or down Vector3 targetPosition enemyManager.activeEnemies enemiesInRange 0 .transform.position targetRotation Quaternion.LookRotation(targetPosition turretPosition) float rotateSpeed 2.0f Time.deltaTime platform.transform.rotation Quaternion.Lerp(platform.transform.rotation, targetRotation, rotateSpeed) Rotate GunBox TO DO This part is not working Transform gunBox transform.root.FindChild("Armature BaseBone PlatformBone LowerArmBone UpperArmBone GunBoxBone") Vector3 gunBoxPosition gunBox.position float angle Vector3.Angle(gunBoxPosition, targetPosition) gunBox.RotateAround(gunBox.position, Vector3.left, angle) Debug.Log(angle) Here's a picture of the turret to give you an idea what I'm working with. You can see in the screenshot that the bone's default X rotation is roughly 50. Enemies walk through the trench around the turret. The PlatformBone rotates everything from the silver platform upwards. I also don't understand why the line below makes the turret rotate instead of tilting it. I would expect to rotate the turret around the Y axis to keep it flat on the floor and face another direction. Yet I seem to have to do the opposite (If I select the PlatformBone its Y axis is facing up as expected) turretPosition.y 0 0 the Y axis to stop the turret tilting up or down |

0 | Show hide soft keyboard on demand I'm writing simple chat app using Unity. The problem with Unity's default implementation of soft keyboard visibility is that it hides itself when i'm clicking outside of keyboard panel. What i want is that keyboard stays always shown until i explicitly tells otherwise. For a couple of days i tried to find similar questions but none of them helped me. I have very little experience in "native" android development (i.e. Java). So far i managed to create simple native plugin for Unity. I tried to manually open keyboard with this code imm (InputMethodManager)context.getSystemService(Context.INPUT METHOD SERVICE) imm.toggleSoftInput(InputMethodManager.SHOW FORCED, InputMethodManager.HIDE IMPLICIT ONLY) The result was fine, except the keyboard had InputType set to TYPE CLASS NUMBER. For my app i needed TYPE CLASS TEXT. So i tried to research how to set InputType and stumbled on fact that this property can only be changed inside EditText object. As i'm writing my app in Unity, i had no way of finding my InputField's inside native code. So i tried to create EditText inside my native plugin. I followed the logic that if i create custom EditText, place it inside main layout and set visibility to NONE or make background transparent, then i can set focus to that element and be fine FrameLayout myLayout activity.findViewById(android.R.id.content) focusedText new EditText(context) focusedText.setFocusable(true) focusedText.setInputType(InputType.TYPE CLASS TEXT InputType.TYPE TEXT VARIATION NORMAL) myLayout.addView(focusedText) focusedText.setFocusableInTouchMode(true) focusedText.requestFocus() focusedText.setBackgroundColor(activity.getResources().getColor(android.R.color.transparent)) imm.showSoftInput(focusedText, InputMethodManager.SHOW FORCED) The end result was a mess. Soft keyboard behaviour became undesirable. In order for keyboard to show, i first needed to select InputField, then i would see transparent EditText be created in the middle of my layout with all input characters visible.

0 | How can I display a 3d object and my player on a canvas? The main goal is to animate my player with animator on a canvas. The problem is that any 3d object (my player, a cube) I drag over the canvas is transparent not seen. The main camera is set to Clear Flags Depth Only and Culling Mask to Everything. The Main Menu Canvas is set render mode to Screen Space Camera and I selected the main camera. The Main Menu Background Material is set to New Material I created and on the new material I added a shader I created that make this image to be blur. The main camera settings screenshot And the Canvas settings And the Main Menu Background settings You can see in all the screenshots in the scene view top left that my player and the cube both are transparent on the canvas. Now if I change the Main Camera Clear Flags to SkyBox then I see my player and the cube but also they are not looking like they should be with the texture materials and also I don't want the Main Camera to be the clear flags on SkyBox I want the objects to be over the blur image so the Main Camera should be clear flags depth only. The main goal again is to put my player on the canvas with the blur image and animate my player. This is for my main menu. The canvas that will display the player if the player will be on his own canvas should be transparent and only display the player so the canvas will not overlap the other cnavas with the blur image. I want to animate using animator the player not only to display it as static object. This is a screenshot of what I mean I used paint to cut my player and put it on but the player canvas should be transparent or without a canvas the player should be on like the ui button on the left Another screenshot. On the top it's the scene view window the player the ui button and the blur image. On the bottom the game view window the ui button is on the blur image. I want the player to be the same as the ui button on the blur image and then to animate the player. Not like in my other screenshot the player should not have a skybox background or something it should be like the ui button on the blur image |

0 | How can I prevent a latitude longitude based chunk system from Mercator projection stretching? I'm working on an little mapbox based game and I'm currently working on an latitude longitude based chunk system. The distance between each of them should be the same. As you can see in the example the width and height of each chunk are equal. The little grey square is just the chunk middle. Those chunks were created near latitude longitude zero, where they aren't effected by the Mercator projection. But due to the Mercator projection the distances between the chunks are increasing as more as they move away from the middle (they look kinda stretched). As you can see the distances between each one aren't equal anymore. The height of each of those chunks did increase. Here's another picture of the Mercator projection to visualize what I mean The chunks of the first picture were created near the middle of the word map (where the big black upper arrow points towards). The chunks from the second pictures were created near the bottom of the world map, where the other arrow points towards. The type of game I'm developing requires equal chunk sizes and also it doesn't look that good when at some point the chunks look different due to the stretching. I want to achieve a chunk system like this on the mercator projection I calculate the chunks as follows First we need the player latitude longitude coordinates 3.0146683, 5.3046076 One latitude is about 110.57 km gt 110570 meters. One longitude is about 111.32 km gt 111320 meters. One chunk should be about 750 meters on the map. Because latitude and longitude got different ranges we need to adjust the chunk size. One latitude factor 110570 750 147,43. One longitude factor 111320 750 148,42. One latitude chunk size 110570 147 750 meters. One longitude chunk size 111320 148,42 750 meters. (Maybe this step is unnecessary) Now we convert the Lat Lng to meters. Latitude in Meter 3.0146683 110570 meters 333 331.873931 Meters. Longitude in Meter 5.3046076 111320 meters 590 508.918032 Meters. Now we need to calculate the meters till the last chunk by using modulo. Latitude Modulo gt 333 331.873931 modulo 750 331 meter. Longitude Modulo gt 590 508.918032 modulo 750 258 meter. After that we are able to calculate the Latitude and Longitude chunks. Latitude chunk position 333 331.873931 331 333 000.873931. Longitude chunk position 590 508.918032 258 590 250.918032. When we didive that now through the chunk size we get the actual chunk position. Chunk X 333 000.873931 750 444,0011. Chunk Y 590 250.918032 750 787,001. Rounded Chunk X 444 Chunk Y 787. Now we know that the player stands right in this chunk 444 787 . In the next step I just calculate the Chunk X and Y back to latitude and longitude and convert them via transform.AsUnityPosition to 3D coordinates, where I place those grey objects then. So basically I need a way to have the same visual distance between each of those chunks. Or either a way to change the projection from Mercator to a square projection, where nothing is stretched. I never worked with mapbox Google Maps before... so I'm a newbie. Or is there maybe a formula I can use to prevent my chunks from being stretched by the projection? Thanks for your time and attention! ) |
0 | Unity inconsistent memory profiling when running same scene I'm in the making of a 2D silhouette style game where I'm trying basically 2 setups One where it consists only of sprites, One where it consists of a mix of sprites and meshes with NO texture. Now, I'm experimenting with the two as I wish to want the scenes to take up the least memory. I have these weird outcomes SPRITE SETUP Total 280 MB, Textures 155.5 MB, Meshes 1.7 MB Total 249 MB, Textures 151 MB, Meshes 4.1 MB Total 279 MB, Textures 151.0 MB, Meshes 10.8 MB SPRITE amp MESH SETUP Total 334.4 MB, Textures 188.2 MB, Meshes 1.8 MB Total 241 MB, Textures 148,0 MB, Meshes 2,3 MB Total 253.1 MB, Textures 157.7 MB, Meshes 4.2 MB Total 301.8 MB, Textures 157.7 MB, Meshes 8.4 MB Total 234.8 MB, Textures 145.3 MB, Meshes 1.9 MB Now, I find these result strange because It was checked on the exact same scene (the mesh setup had same amount of objects, just swapped the sprites for meshes) and the data is inconsistent, meaning there is about 100MB difference between the same mesh scene A scene of mostly mesh with zero textures uses more, or at least not less, textures than a sprite only scene?? By taking a look at the data above, I would require someone skilled to guide me through this. Shall I keep using those meshes or just go for sprites? What is really goind on here with this data? |
0 | Importing audiofile into Unity3d gets shown after ending playmode I am working on a game where the user has the possibility to import custom audio tracks that can be listened to during the game. For this I am making use of System.IO.File.Copy method. This works, there are no issues or flaws here. When I inspect the target and destination folder the file(s) get copied properly and show up in the folder. The issue however is that the Unity Editor doesn't show the file despite it actually being there. During play mode in the Unity editor the new file isn't shown in the resources folder (which I use as destination for now). When I use windows file explorer I can clearly see the file in the corresponding folder. Using debugs (in Unity) also state that the folder is empty, however when I use debugs outside of Unity it shows that the folder contains the copied item. Keep in mind that these both debugs are called roughly at the same time. I have tested this in many ways to be 100 certain that Unity doesn't see the file, while it is there. So once I stop playmode it starts loading importing processing the new file and then it shows up in the folder in unity as well. When I launch playmode after this the file is indeed loaded and included in the game as well. I however need this to happen without having to stop playmode. So there is probably some type of processing that I haven't called for Unity to process the addition of the new file and for it to be visible. So in a nutshell basically copying a file from folder to folder isn't enough for Unity to directly utilized in the same play session (and all after). How can I make the audio file directly showable and accessable? There aren't any errors or warnings. The file plays correctly after it has been processed. I am at a loss with this issue bug. |

0 | Unity LWRP Sprite Renderer Sorting incorrectly after upgrading I'm making a project where every tile is a sprite renderer, this would work fine in the old unity system (from the fact that it used it until recently), but upgrading to the LWRP broke the sorting of the sprite renderers. Previously, I didn't have to change the order at all, but now they phase in and out of each other based on the position of the camera, like the picture shown below. They all use LWRP 2d Sprite Lit Default, as any other of the LWRP materials do not use the texture from the sprite renderer and instead make it all black. I do not want to use sorting layers because I have meshes sprinkled in, and what i have seen there is no way to control if the mesh is on anything but order 0, besides some hacky way. Even using a box mesh it gets cut off when the floor is closer to the camera. Here is what it looks like far away, the floor should be there the entire time and not have the darkness of the walls seeping down into them. I don't think I can use mesh renderers either, as I want a way to control the texture from each individual object, and share a material through all of them. I think if I used a mesh renderer I would have to use a material for each different tile, and I would not be able to tile them like I am doing now. |
0 | How can I reduce Unity's package size? I've been experimenting with Unity3D 4.3's 2D features. I've created a simple prototype game to learn how Unity works, how to create sprite animations, collisions and all the basic things. My project compiled for PC was approximately 23MB. The game includes one larger bitmap for a background (originally 1MB JPEG). The player spritesheet was black and white with almost no details. So all the assets had (in their original, compressed form) no more than 2 3 MB. I ended up with one large executable file (about 10MB) and a folder with .dll files and assets (5 6MB). Can that be reduced? My experience with C WinForms code makes me believe that executables and DLLs grow that big only when binary data was involved (images, sound, etc). Is that the case with Unity? I am interested in developing 2D applications for Android and iOS, where low total app size is a priority. |

0 | Client not executing commands in Unet Edit Okay, so I partially solved the problem by adding a rigid body component to the capsule. I read somewhere that apparently you have to have one in order to move on the server. Problem 2 The next problem I have is that I can now move a capsule that is spawned by the client fine and the host can move it as well as many times as they like. The problem I am getting now is that when the host spawns a capsule the client cannot move it at all and I get a sort of glitch effect on the client side and the capsule still doesn't move on the host side. Is there a reason why it would only work one way and not the other way around? I thought at first it might have to do with Spawn vs SpawnWithClientAuthority but that doesn't seem to make a difference. Project Summary I have a pretty simple multiplayer project, all I want to do is have one player host and the other join as a client. Once they are joined together the two players can spawn a capsule and then when the user clicks on a capsule. They should be able to pick it up and move it around the scene and the other player should be able to see this action. I can get both players to connect to the server and spawn their own capsule and both players can see this. The movement script is done as well. However, it is only transmitted on the host side. When the client picks up the object it does not update on the server. Problem I have done a bit of debugging and have found that when I call the command on the client it is not being executed at all through line breaks and simple debug statements. Code public void OnInputClicked(InputClickedEventData eventData) Debug.Log("clicked") if (isLocalPlayer) if (Physics.Raycast(transform.position, direction transform.forward, hitInfo out hit, maxDistance range)) Debug.Log("Hit capsule") objectID GameObject.Find(hit.transform.name) objNetId objectID.GetComponent lt NetworkIdentity gt () playerIDThatClicked player.GetComponent lt NetworkIdentity gt () CmdAssignAuthority(objNetId, playerIDThatClicked) Debug.Log("grabbed") else if we are releasing the object we want to unassign our authority if (objNetId ! null) CmdAssignAuthority(objNetId, playerIDThatClicked) objNetId null Debug.Log("released") Command void CmdAssignAuthority(NetworkIdentity target, NetworkIdentity player) Debug.Log("inside cmd") current target.clientAuthorityOwner playerconn player.connectionToClient if (current ! null amp amp current ! playerconn) Debug.Log("Had authority now removing and replacing") target.RemoveClientAuthority(current) target.AssignClientAuthority(playerconn) else if (current ! null) Debug.Log("removing authority") target.RemoveClientAuthority(current) else if (current null) Debug.Log("No authority, adding one now") target.AssignClientAuthority(playerconn) else Debug.Log("CmdAuthority error") target.RemoveClientAuthority(playerconn) Question Am I calling this command correctly? The script is attached to a player prefab and the capsule prefab contains a network id and a network transform. I am pretty new to Unet and this feels like a noob mistake. |
0 | Unity Proximity Warning System Trigger issues I'm trying to set up a proximity warning system but I'm having some trouble. To simplify things as much as possible I have two game objects in a scene (Object1 and Object2). Object1 has a large child object (twice as large as Object1 or Object2) which has no mesh renderer, but has a box collider (with the Is Trigger box ticked). Object 2 has a rigidbody component. When Object1 gets close enough that it's child's Box Collider overlaps with Object2's rigidbody, a script on Object1 should Debug.Log the name of the object it's close to once a frame until Object1 moves away. My code is as follows public Collider objectCollidedWith void OnTriggerStay(Collider other) objectCollidedWith other.transform.GetComponent lt Collider gt () void Update() Debug.Log(objectCollidedWith) Unfortunately, something about my setup isn't working. The console just shows "null" once a frame and the objects getting close doesn't change this. Can you tell me what I'm doing wrong? Many thanks for your time. |

0 | Camera relative movement is pushing into off the ground instead of parallel I'm building upon roll a ball tutorial in unity, and I have managed to rotate the camera around the ball just fine with the code below. But there's one problem. In this code, when I add force to the ball, with W for example, the force will be added in the exact direction the camera is looking at the ball, meaning pushing the ball onto the ground, increasing friction and lowering speed.

0 | Problems with gravity and box colliders in Unity 3D I have a game character that can jump or roll in order to avoid obstacles. He is able to roll while on the ground and he can also roll while he is in the air after jumping. Everything was working fine when I made him roll. I want to make it so that when he rolls while he's in the air after jumping, he would fall at a faster pace than if he was just falling normally. So I did this in my c script IEnumerator IncGravAcc() Physics.gravity new Vector3(0, 50f, 0) yield return new WaitForSeconds(2f) Physics.gravity new Vector3(0, 9.8f, 0) I call this coroutine in the function that runs when the down arrow is clicked. Everything is working fine. When he rolls while in the air, he falls at a faster than normal rate. However he doesn't land properly and he just falls right through the platform like it's not even there. Here's a video to show what I mean https youtu.be sirc4L3MnqM I have a box collider, not set to isTrigger, on the player (you can see it, the green box, right underneath him in the video) and the player's also a rigidbody. The platforms don't have rigidbodies on them but they do have box colliders set to trigger. You can see the platform's box collider in the relation to player's box collider in the picture provided (the platform's box collider is the larger one of course) How do I get it so that the character doesn't fall through? Please let me know if there's anything else you need to know about the project. Thank you for helping me! |

0 | Creating an object in javascript with unity (unityscript) So I have a ton of experience with JavaScript (its what I do for a living) but I am new to unity. I have built a game engine in javascript but now want to move it over to unity. I have been trying to implement my player class but am running into this error. I have a getter function for my level up stats. and inside of my level up function I call that getter function and store it now I know this would work in normal javascript but its not in unity and I have having a heck of a time googling any information on objects in unityscript. Here is the relevant code function level getter() return base level exp float , lvl exp modifier float , current level int function level up() var level object new Object() level object level getter() level object.current level 1 level object.base level exp level object.base level exp level object.lvl exp modifier level setter(level object.base level exp, level object.lvl exp modifier, level object.current level) I guess my first question is, is it even valid to return an object like that in unityscript?(in the level getter() function). If its not valid what do people suggest I do instead. Set a getter function for each var? My second is how do I declare level object so that it can accept the return if it is valid, and so that I can access the members of the object. I have been looking around at tutorials and google for several hours now and have found nothing to clear up my confusion over objects in unityscript. So any help would be appreciated. |
0 | pre load new scene in unity async but don't show it I have a top down dungeon crawler in 3D where I show one room at a time. Each room is it's own unity scene. Each room has an exit point that when clicked I fade the screen, load a new scene and then fade in the screen. What I'd like to do, but not sure how, is to pre load the next possible scenes (note the S, there will be 2 but could be more. 2 because it's the next room or the previous if the player decides to go back) while in one scene. I know the scenes that are possible to get to, but how can I pre load but not show them and because there is more than 2, I assume if they go in one direction, there is a pre loaded one that I need to unload. Overall I want to do this to make a faster smoother transition between rooms, but I want the one room at a time for artistic style. |
0 | Unity build does not launch and leaves no logs errors I have released my first title Audio Infection ( https store.steampowered.com app 911580 Audio Infection ) for a bit over a year ago. Recently 1 user has so far encountered an issue where the game does not launch. He is the only user that encounters this problem. He has this issue on both Win 7 and Win 10. His system specs are fine and his drivers are up to date. The game does not leave a log file, rather it looks like it is unable to boot. There are no Windows error reports on it either. I watched it through Discord screenshare because I could not properly understand his issue. I had asked a few other random people to test my game and demo (he has the issue with both, the demo and full version) however no one else (including me) is able to reproduce this behavior. At this point I have tried updating Unity from 2018 to 2019 (no change in behavior) added manual logging (with no results) updating drivers (on his system) installing Visual C (on his system) empty project with Unity sample scene (he was able to load the sample scene!) deleting crashhandler.exe (used to fix similar issue in the past based on older threads) modifying files deleting and downloading the files What else can I try in order to figure out what is causing the issue? I am honestly clueless. Since the sample project was able to boot on his system there is definitely something wrong with the build on my end. However he is the first person with this issue. It doesn't even get to the point of launching on his system and it can't be found in the memory either. It is almost as if Windows is blocking it from launching, however that is not the case. But the result is very similar to that. There is a free demo on the store page available in case you want to see if it boots on your system. It works for both VR and non VR systems. When no VR devices are detected all VR related contents are disabled. This has been thoroughly tested and worked on loads of different Windows systems with different specs, with VR and no VR. Once again, there are no errors, no logs, the build doesn't even make it to that point, yet that exact same build works for literally everyone else on various systems. I am absolutely clueless about what to do in order to resolve this issue. Any help advice or pointers towards the right direction are greatly appreciated! PS he is not a troll, I have known this guy for a long time now and he genuinely wants to support me. |

0 | Creating multiple levels in Unity without duplicating scripts I'm trying to create a falling word typing game like z type. I have used the code provided here I want to create multiple levels in the game, and it seems like I need to make some changes in the code for each level. For example, in the word display file, I want the active word to be changed to red for level 1 and blue for level 2. So I created a copy of my level 1 scene, created a duplicate WordDisplay script file, changed the code for active word to blue.... public class WordDisplay MonoBehaviour public Text text public float fallSpeed 1f public void SetWord (string word) text.text word public void RemoveLetter () text.text text.text.Remove(0, 1) text.color Color.red ... Here's the duplicate script I made public class WordDisplay1 MonoBehaviour public Text text public float fallSpeed 1f public void SetWord (string word) text.text word public void RemoveLetter () text.text text.text.Remove(0, 1) text.color Color.blue ... Then I made a copy of the WordSpawner as well because I was getting an error I had to change the method's return type to to WordDisplay1 and then got one more error which was in the Word file, leading to more changes... public class WordSpawner MonoBehaviour public GameObject wordPrefab public Transform wordCanvas public WordDisplay SpawnWord() ... public class WordSpawner1 MonoBehaviour public GameObject wordPrefab public Transform wordCanvas public WordDisplay1 SpawnWord1() ... Then I created a duplicate of the word prefab and selected the appropriate word spawner file... All of this seems like too many changes for a simple colour. Is there a better way to have multiple levels without having to create a duplicate of all these files and the word prefab? |
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. |

I do not need to know how to render this, all I am looking for is some kind of function or something that I can use to tell the character to walk along the ground rather than walking through it.

0 | Effects of collisons broken glass, damaged cars, how are they created? My question is related in particular to achieving the effects of collision in game engine, how is this done? I have searched a bit, read from the internet and went through a few tutorials, and saw that one way to create one of the effects, explosion, or something breaking is to create the model in pieces, and apply force (in a game engine such as Unity 3D) to make the pieces fly off. It seems to be a solution, but it doesn't address the problem of items that are vaporized in a big explosion, with so many pieces. How is this done? Basic methods and tricks etc would be helpful. Secondly, the problem of things bending and getting damaged on impact, such as a car's front end destroyed when it hits a wall? How is this done? One thing that comes into my mind is to create each component of a car in a different state as an animation in 3Ds Max or Maya, and then in the engine, according to the collision, switch the model state in the time bar. Is this how it is done? Finally, what about materials, such as net of a basketball net, or a soccer goal net for example? Effects of ball hitting it can be calculated and applied in a script, but how to make the net bend and stretch with it? Is it done through models or materials? Also what about a flag fluttering in the wind? My questions are specific to game engines, particularly Unity3D. Some good links on the subject would also be helpful. |
0 | Building a game project in C for Unity in VS? Say that a project needs to be created from scratch for later use in Unity, for scripts. What is the ideal way to setup this without using a template in Visual Studio? Can this be created in C with some simple classes and one or two game loops? |
0 | LeanTween How to check if gameObject is destroyed? I am trying to animate a gameObject using LeanTween which has got destroyed already. The MissingReferenceException occurs in LeanTween.setOnUpdate() The null check doesn't work either (gameObject ! null) I have used LeanTween.cancel(gameObject,false) but it still throws an exception. |

0 | Why does Unity not follow the z value when drawing text? I'm currently working on the credits of our game. For this I'm using multiple elements in a canvas I want the order that these elements are drawn in to be as follows, I gave them a z value based on this Z Object Object type 0 Text (The actual credits) Text 1 Hider (Green for demonstration) Sprite 2 Divider (The grey line) Sprite 2 Gametitle Text The camera has a z value of 10. The canvas is in "Screen Space Camera" render mode. But for some reason Unity is not drawing these items based on these Z values As you can see, the Divider is drawn over Text, but Text is above Hider and Gametitle. Why is this happening and what can I do so the credits get properly drawn? |
0 | Unity Photon Networking Cant understand OnPhotonSerializeView In all tutorials I see that an object sends data over the network and receives the data. For sync in the same method Code void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info) if (stream.isWriting) stream.SendNext (transform.position) stream.SendNext (transform.rotation) else Debug.Log("never gets called ") never gets called... transform.position (Vector3)stream.ReceiveNext () transform.rotation (Quaternion)stream.ReceiveNext () But when I test my code, the lower part, where the data gets received, is never executed! I never see the logs. But the object is SYNCHED because it is set in the inspector But the problem is that the object is not interpolated so it looks kind of funny. So, I need to know how can I make the upper method to work so I can do some interpolation stuff. |
0 | How to move the player while also allowing forces to affect it For now, that's how I move the player rb.velocity Vector2.right input.x And I affect him a force while he is damaged by an entity rb.AddForce(Vector2.right force) It works fine, until I try to move while I'm damaged by an entity. Since my velocity input.x while I move, I can't affect any forces to it. I've tried to summarize velocity rb.velocity Vector2.right input.x But then I need to clamp the speed and if I clamp it, my force which is affected to player is also clamped. How can I resolve this problem? |
0 | How to share some elements of array with different players on Photon in the same Room? Unity3d I want to assign cards to different players in the room. I've a Class "Cards" that contains an array of 52 cards like this "2 of spades","3 of spades"....... and so on. All i want is to assign random indexes or values to different players on the basis of which I'll instantiate Cards Sprites. How can I do that? I've heard that there are RPC calls but how do I manage to make a "Middle Man" script that would deal with different players? |
0 | How can I implement a revealing light beam? In SEARCHLIGHT, you control a ray of light that illuminates incoming enemies that are otherwise invisible in the night sky. Here is an illustration How would I go about doing this, preferably in Unity? I imagine this is less about lighting and more about shaders, but I'm not sure on details. The fact that I know very little about coding shaders makes it worse. If it is about shaders, what are the specifics? Is there a stretched quad that moves with said shader applied to it, or perhaps is using the Line Renderer a better option? As a beginner, may I try to achieve a similar effect, or should I leave it for when I'm better? (P.S. The game was made in Unity. Here is its itch.io page.) |
0 | Unity mailchimp Klaviyo subscription form Hey everyone so i want to add a subscription form on my game. so far i can send data to a database and display them on a leaderboard, i found a similar question here but its a bit outdated. Ideally i would like to use klaviyo but since this is the only lead i have i might want to get familiar with how it works! using System using System.Collections using System.Collections.Generic using UnityEngine using UnityEngine.Networking using UnityEngine.UI public class MailingScript MonoBehaviour public InputField emailField public InputField nameField public void onClick() StartCoroutine(SendToMailChimp()) private IEnumerator SendToMailChimp() WWWForm form new WWWForm() form.AddField( quot EMAIL quot , emailField.text) form.AddField( quot b 0f079b7af1cef143021ff4236 6cd74c0a6a quot , nameField.text) form.AddField( quot subscribe quot , quot Subscribe quot ) UnityWebRequest www UnityWebRequest.Post( quot https slaga games.us1.list manage.com subscribe post?u 0f079b7af1cef143021ff4236 amp amp id 6cd74c0a6a quot , form) yield return www.SendWebRequest() if (www.isNetworkError www.isHttpError) Debug.Log(www.error) else Debug.Log( quot Registered quot ) this is my code so far but it wont do anything. i have a same code for the database which works! |
0 | Unable to move GameObject? This simulates a GameObject swinging between two positions. I am unable to manually move a GameObject on the Y axis using the Unity editor (in scene view) when the following script is attached and running, it's like a solid animation Vector3 min, max void Update() min wall1.position new Vector3(4,0,0) max wall2.position new Vector3(4,0,0) transform.position Vector3.Lerp (min, max, (Mathf.Sin(2 Time.time) 1.0f) 2.0f) |
0 | Limit rotation angles for Quaternion I have a short snippet that's rotating the meshes of the wheels as I'm driving forward, but it's also rotating wheels to match the direction I'm turning, and I wish to turn this off completely. Quaternion quat Vector3 position m WheelColliders i .GetWorldPose(out position, out quat) m WheelMeshes i .transform.position position m WheelMeshes i .transform.rotation quat How would I lock what angles I don't want the wheel meshes rotating? |
