0 | How to enable the option "edit physics shape" in the Sprite Editor? I can successfully import .png files, create tilesets, and use them in my tilemaps in Unity. Thanks to DMGregory, I just learned that there exists an option to customize the Tilemap Collider 2D in the Sprite Editor, which allows me to set a custom collider for every tile instead of going through them one by one. The steps I follow while creating a tileset in Unity is as follows. Import the .png file. Open the Sprite Editor. Select the option Multiple for Sprite Mode. Select Slice from the Sprite Editor. Then, I create a Tile Palette in a folder, drop and drag my created tiles, and start creating my level. I have never encountered the option to modify the colliders tile by tile. What am I doing wrong? |
0 | Elegantly exposing properties in Unity inspector There are various game objects in my scene that share some common characteristics, so I created an interface, like so public interface IHasLimitedRangeOfMotionAlongZAxis float MinimumZ get float MaximumZ get For certain types that implement this interface, I would like MinimumZ and MaximumZ to be publicly assignable in the Unity inspector. Therefore, I would like to be able to expose these properties in Unity. I am aware that one approach is to write C scripts in the Editor folder to implement an ExposePropertyAttribute (see here). However, this approach is unsatisfactory for two reasons My solution is not co located with my Assets folder. I write my code in a separate solution, and then use pdb2mdb.exe to import my scripts into my Unity scenes. (The reason for doing this is to avail myself of C language features introduced beyond C 4.0, which nonetheless target .NET Framework 3.5.) I shall have to create a custom editor for every single type that implements the interface with publicly assignable properties. This leads to a lot of boilerplate code. Is there a more elegant approach than adding private backing fields with the SerializeField attribute for all of my public properties? |
0 | How do I connect Unity to a server backend developed in .net core? I'm currently running to a wall in my game development and I need now some discussion to clear my mind... In my mind I have a plan for some little online game (focused around clicking and idling), which I imagined could be served both on website and winapp, and in future even in mobile platforms. I have chosen C for it, build some server backend (join server, game server), but 'cause I want this server components be runned on linux, I have chosen .net core. Which is now my problem, because I'm building the game client in Unity, which only works in .net standard. My main problem now is that I have build some quot base network library quot for communication, written in .netcore with plenty of NuGet packages, which I now have implement to Unity to get it work, but there are now conflicts (the main one is that unity is using another version of System.Threading). Now I am wondering what steps should I choose nexts... There are some work behind now (but not so much, there are only some basic proceses for login and creating game worlds), so probably make that base network package compatible with .netstandard and .netcore. Or I am thinking if it isn't more suitable to choose some another technology like c and some 2D engine in it (which to choose?). What are you opinions? And what would you do in this situation? |

0 | Skipping a loop in foreach? I'm trying to get Unity to filter through a list of nodes, but I am unsure on how to do so.

Any advice on the proper syntax to deal with this will be greatly appreciated. Also, an example of how do peform filtering using LINQ will be helpful. |

0 | Detect collision without reaction Okay, so this has been bugging me for quite some time now. I'm making an old school platformer type of game in 2.5D, I want objects to pass through each other, but I still want a collision to be detected. If the player gets hit by an enemy, I just want to detect a collision for receiving damage to the player, I don't want the player to move on impact, and I just want the enemy to continue moving where he was heading. I'm using rigidbodies and box colliders on my objects. First I thought using triggers combined with ignoring layers was the solution, but apparently trigger events aren't called when ignoring layers. I still want to be able to use AddForce and stuff for moving objects. Is there someway I can still utilize Unity's OnCollision... OnTrigger... Or other... for just detecting a collision and having no impact movement added when a collision occurs? Have a nice day! |

0 | How to load and unload objects at a certain radius from the player? I am making a procedurally generated space exploration game in unity. I'm currently generating 5000 stars in a cube of a fixed size. Each star just gets a random 3d coordinate. What I would like to do is to dynamically load and unload stars at a certain radius from the player. This would be the maximum view distance. The algorithm that does this must be working with a seed for the universe, as the stars need to be loaded in the same spot when you revisit them. My idea is something like in the amazing Space Engine. I have pretty much no knowledge of algorithms that can do this, so I ask for your help. |

0 | Is it possible to get object rotation in a shader for dynamically batched objects? All the batched objects have the same rotation. To simulate the effect of directional light I need to determine the object sides actual (world) directions.

0 | Should I code game logic separately from game engine scripts I'm developing a game in Unity3d, economic strategy. I wonder if I should code logic inside unity scripts, or write it as an external module library? By game logic I mean game model, which describe game entities, they relation with each other, their methods. And this logic has nothing to do with and doesn't need to know anything about networking, rendering, representation etc. If I do it inside unity scripts, then logic is tied to unity engine and I don't see a way to implement multiplayer(client server) without rewriting whole logic for server side, where unity cannot be used. I would like to define logic outside of scripts, and later, reference it inside some "main" unity script. This way I could implement multiplayer easily. Is this a common practice, or should I avoid it, or maybe there is some alternative patterns? |

What i want is a solution that will run all over the grid, and check if a group has less than 3 triangles then do (A) if it has 3 triangles then do (B) if it has 4 triangles then do (C) etc ... Am not sure about this, but i thought the best way is to have a list for every group, and then check those conditions over the lists. I tried it here but the list keep re initializing itself, so it always either have 0 cells or 1 public List lt CellSetup gt listedCells(int y, int x, int value) List lt CellSetup gt cList new List lt CellSetup gt () base state if (!gSetup.isValidLocation(y, x) gSetup.getCell(y, x).value ! value gSetup.getCell(y, x).cMAtch.isInMatchPool) return cList keep track of matched cells gSetup.getCell(y, x).cMAtch.isInMatchPool true cList.Add(gSetup.getCell(y, x)) collect List lt CellSetup gt up listedCells(y 1, x, value) up List lt CellSetup gt left listedCells(y, x 1, value) left List lt CellSetup gt right listedCells(y, x 1, value) right List lt CellSetup gt down listedCells(y 1, x, value) down return cList The result of that method when its called here for (int y 0 y lt gSetup.cell2DArray.GetLength(0) y ) for (int x 0 x lt gSetup.cell2DArray.GetLength(1) x ) print(listedCells(y, x, 1).Count) is printing "1" three times and "0" 22 times.

0 | Why don't my generated instances update when I change their prefab? I m making an Editor tool a ScriptableWizard that instantiates a prefab on a grid. But I find that when I update the prefab, the instances don t update. When I instantiate prefabs interactively in the Editor by dragging them from the Project panel to the Scene or Hierarchy, then updates to the prefab affect the instances as expected. I see another difference between my scripted instances and the ones created when I drag the prefab into the scene when I do it interactively, the instance in the hierarchy is listed in blue. But the instances I create from script using the same prefab are listed in black, similar to objects created directly in the scene. Here s the hierarchy the JitterPrefab was dragged into the scene, and the ones under gridParent were instances of the JitterPrefab generated from my script Here s how I m generating the instances public GameObject prefab ... void OnWizardCreate() ... Transform instance Instantiate (prefab.transform, pos, rot, parent.transform) instance.name string.Format ("L 0 D2 R 1 D2 C 2 D2 ", l, r, c) ...

Why are my scripted instances no longer connected to the original prefab? And, separately, how to I tell in the editor (or in script) whether an object in the scene is an instance of a prefab or not? |
0 | Unity OnRenderImage hides UI I have a component which renders a few different cameras and the images. However, this obscures my UI when in Screen Space Overlay mode. I can put the canvas in WorldSpace mode, which works, but then the UI is affected by the image effect I've built and is, of course, not locked to the camera. Suggestions? Update additional details At design time, the OVR camera rig contains a single camera centered between the "eyes." This component is attached to the camera rig's centerEyeAnchor. At run time, the rig creates two additional cameras one for each eye. These aren't supposed to be modified by user code. (Among other things, their projection matrices are pretty weird.) I need to modify the image per eye. I created a new component which create two additional cameras per eye. One renders a low res version of the entire scene, the other renders a high res image of a portion of the screen, each to a dedicated RenderTexture. Pseudocode void Update() called once per frame called twice per frame once per eye void OnPreRender() called twice per frame once per eye void OnRenderImage(RenderTexture source, RenderTexture destination) low res render of entire scene var camOuter m cameras ... hi res render of part of the scene 10 20 of original image area var camInner m cameras ... update cameras to match current eye camera camOuter.copyFrom(Camera.current) camOuter.targetTexture m outerTexture render scene to low res texture camOuter.Render() camInner.copyFrom(Camera.current) camInner.targetTexture m innerTexture target texture that the Oculus wants to render to var ovrTexture Camera.current.targetTexture save projection matrix var originalProjectionMatrix camInner.projectionMatrix var scale new Vector3(m innerTexture.width 1.0f ovrTexture.width, m innerTexture.height 1.0f ovrTexture.height) zoom pan matrix to clip to part of the scene var gazeMatrix Matrix4x4.Scale(scale) offset projection gazeMatrix.m03 (1 2 gaze.x) scale.x gazeMatrix.m13 (1 2 gaze.y) scale.y camOuter.projectionMatrix gazeMatrix amp originalPRojectionMatrix render hi res portion of the scene centered at gaze pixel camOuter.Render() restore projection matrix cam.projectionMatrix originalProjectionMatrix composite images m material.SetTexture("InnerTexture", m innerTexture) m material.SetTexture("OuterTexture", m outerTexture) Graphics.Blit(null, destination, m material) (I'm also worried that there may be additional scene renders happening in the background.) The problem is that the UI does not render if set to Screenspace Overlay or Screenspace Camera. I can get it to render in Worldspace, which may be the only way to do this, but then it seems I'd need to create yet another hi res texture matching the viewport dimensions and render the UI layer to that, and keep it locked to the current eye's camera position. Alternatively, I could re use one of the current cameras, I guess, and just tweak its settings. Is there a better way to do this? Ideally, I'd like to have the engine just render the UI as it does in other applications without having to jump through hoops. However, at this point, I'll take anything I can get that works and looks good. Update the 2nd Okay, it looks like the UI is rendered perfectly if I use a regular camera instead of the OVR rig. ( Having the rig in the scene, though, prevents it from drawing at all. |
0 | How to put the game object to the upper left corner of the screen in Unity and make it visible entirely on all screens of mobile devices I have game object which displays health indicator in my 2d video game in Unity. This gameobject contains a lot of sprites and i put it into left top corner of the screen. In my game editor it is visible entirely but on my mobile device is visible only half of it. How can i make it visible entirely on all screens? Can anyone help me to solve this problem please. P.S. I have some ideas how to do this 1. Create health indicator from GUITexture elements. But it is not good for me, because health indicator consists of a lot of small elements and it will take a lot of time for me to resize every GUITexture according to my needs. Put my gameobject with health indicator into another gameobject with zero transform, and then put parent GO into top left screen using Camera.main.WorldToViewport method. But may be there is more easy way to do this? |
0 | Jumping onto higher ground Collider issues What's the general solution to the following character animation problem (I'm using Unity)? You have a character with a capsule collider and a jump animation that allows you to jump onto higher ground (such s boxes, etc.). The character shouldn't be able to jump unrealistically high so she goes into a crouched posture while in the air and the collider is scaled accordingly in an animation curve. However when the character jumps onto the box to land, the character animation (and collider) want to extend back to wards the ground but there is not enough space and either collision detection fails and the character falls into the geometry or the collider starts a collision fight with the box and keeps bumping up and down, keeping the character in an airborne state. Please see screenshots to get a better idea... What would be a good way to work around this problem? |

0 | Ping Pong bat is not detecting the collision with the wall I have been learning Unity for last couple of days. I want to make one simple ping pong game. The idea is simple. The game has a Sphere as a ball, a plane as ground, 2 rectangles as bats and 4 rectangles as walls. Look at the image It is a 2 players game. One player will use 'W' and 'S' key and another player will use 'Up Arrow' and 'Down Arrow' on the keyboard to move the bat up and down. But I have a problem here. If a player moves the bat at the limit (up or down), the bat does not detect the collision with the wall. It just goes through the wall. Look at the image. The bats and the walls have Box Collider, but still the problem persists. So what should I do so that the bat detects the collision with the wall. |

0 | Creating a content pipeline for a Unity I have a game with lots of assets, such as data files, images, etc. My understanding is that Unity is optimized to know about all resources at build time. i.e. binding those assets to Scene GameObjects or prefabs. And for performance reasons, dynamically loading files from the Resources folder is discouraged. My question is how can I set up a "content pipeline" for converting my asset files stored outside of Unity into a format that Unity expects. With the XNA toolset you can create a separate project and "build" the content into a bundle. Is there way to achieve similar results in Unity? Or is the best I can do creating an external tool, and simply copying files into my Unity Textures or Unity DataFiles folder and generate the Unity metadata files myself? If there isn't an off the shelf solution, do you have any experiences or recommendations with solving this problem? |

0 | How should I organize 2D sprites? I'm using a Unity Tilemap in my 2D game, and I have several hundred 32x32 sprites. Most of the examples I've seen using sprites have a few consolidated sprite sheets that contain all of the game's sprites. For instance, I'd have a few 1024x1024 sprite sheets that contain all of my game's sprites. Those examples all say that the reason to do it this way is that performance is improved when sprites are packed together like that. The problem with these large consolidated sprite sheets is that it's difficult to find the sprites that I want when I'm making a tile pallet or animated scripted sprite. For example, I have two 1024x1024 sprite sheets called "House Interior 1" and "House Interior 2" that contain all my walls, floors, furniture, doors, windows, and miscellaneous interior objects. Now I want to create one Unity tile pallet that has only tiles for western style houses and one tile pallet that has only tiles for eastern style houses. Each tile pallet is going to require some, but not all, sprites from both of my sprite sheets (House Interior 1 and House Interior 2). Additionally, I want to create some animated tiles. Each animated tile will use a few sprites from somewhere in the middle of one of the large sprite sheets. My problem is that each sprite sheet image has so many child sprites that it becomes very tedious and time consuming to visually scan through each huge sprite sheet to find the tiles I want, and then drag each of them individually onto my tile pallet. Making animated tiles results in the same problem because when I assign each animation frame, I have to find the correct sprite from a huge list of sprites that are named House Interior 1, House Interior 2, House Interior 3, and so on. I'd like to have smaller sprite sheets that only contain one specific type of sprite, rather than huge sprite sheets of often unrelated sprites. For example, I'd like to have one sprite sheet that has only masonry walls, one that has only brick walls, one that has only the animation frames of a fireplace, and so on. That way it'll be easier to build up Unity tile pallets by dragging several sprite sheets into the tile pallet in the Inspector, and it'll be easier to find my animated tiles because I can easily find the sprites named Fireplace 1, Fireplace 2, and Fireplace 3. So my questions are How big of a performance hit will I experience if I don't pack my tiles together into a few big spritesheets? Is it even worth taking this into account considering modern devices are so powerful compared to what is necessary to do sprite based graphics? Is this a case of balancing the pros and cons of both methods, or is it generally strongly recommended that I large consolidated sprite sheets? |

0 | Smooth Flat shaded meshes cause shadow artifacts (understanding the source of the problem) I'm using blender to create assets to use in Unity3D, and I'm having some trouble understanding how the smooth flat shading interacts with shadows, I'm sorry if it has been asked before, but all the "related" answers refer only to the shading of the object itself, not the shadow it casts. I'm a 3D artist, I do not understand Unity and the mechanics behind it the same way I understand 3D stuff, I'm also trying to understand if the problem lies in the 3D object or some configuration in Unity. I'm using a real time directional light. 1 and 2 are flat shaded. 2 has open geometry while 1 has closed geometry, both have such artifact but it's clearly seen on 2. 3 and 4 both have closed geometry. 3 is fully smooth shaded while 4 is flat shaded. Solution A Mess around with Bias and Normal Bias. With Normal Bias at 0, the shadow artifacts are gone but the mesh itselt gets some other artifacts. Solution B Use Two sided shadows, this method completely fixes the problem, in any situation, but it adds another draw call and makes it more expensive (I'm not 100 sure it does) is this an optimal solution? This same issue was discussed in a closed group but no one could give me a conclusive answer. However, someone who works with 3DS Max said that exporting a mesh with proper smoothing groups does not result in these artifacts, I tested that in 3DS Max and it did not work I think I did it the right way, but I'm not 100 certain. For all the proposed methods, I tested several times, with diferent mesh modifier and exporting options. I'm using mostly .fbx but I also tested in .obj format (which includes a specific option for smoothing groups in blender). Smooth shaded objects work perfectly, flat or smooth flat shaded objects result in this drama. Please help me to bring light to this issue, I might be blind to some obvious aspect, I'm confused because in the other discussion I was presented with contradicting arguments without conclusive proof of anything. Now I don't know if the problem lies with Blender export or Unity configuration. Let me know if I can provide more information. |

0 | Is a mesh OK to use for grass if there will be 1000's of them across the terrain? Am creating a low poly game in Unity 3D for PC. The terrain is made in Blender, so it's a fixed size, but quite large for the player to explore. I want to add things such as grass and flowers, but am not sure the best practices are for creating those types of assets. Is using a mesh for small clumps of grass the wrong way to do this if there will be 1000's of them? I will likely be using the occlusion culling system Unity provides, but I'm not sure if I still need to look at doing things such as grass in a different way for performance sake. |
0 | Speech recognition in Unity 5 for Android I've been working on a game in which the player have to say particular words to perform various tasks. For example, if the player says "boat", a boat pops up in the game. The game I'm building is specifically for offline play, on an Android device. Just for reference, there is a game titled "Pah!" which implemented this offline speech recognition for one specific word. In this game, when you say "pah", the GameObject moves jumps. I've tried everything from speech to text to forums, and even tried Google and used using Windows.Speech, but nothing works. From what I've learned, I need to use the Google speech API for Android speech recognition. I am a bit new, when it comes to Java. I gave it a try and created a basic script, which I thought might take at least one input in speech from the player, but Unity disagrees and says it couldn't recognize the script. I created another script in C , by taking help from tutorials, but when I switch the platform from Windows to Android it doesn't work, because Unity.Windows.Speech is a Windows namespace I am blank, and hence, this question. I have googled, visited forums, and even looked at YouTube videos for an answer. I came across a few Unity assets which I paid for, and they are all garbage. If anyone could help me, how do I implement speech recognition in Android, using Unity 5? |

0 | collision detection and normals from rigidbody Until now I've been developing my player character using a Character Controller, but have since decided to switch to rigidbody due to the controller's limitations. In order for my movement code to run as expected I need to know when the player is colliding with anything, and the normal of the surface it's colliding with. This is easy with a Character Controller, but is there a simple way to do it with a rigidbody? Here is a stripped down version of the script I'm using for collisions. Used in other scripts (Necessary) public GameObject ground null public Vector3 groundNormal public bool onGround Used internally public bool isColliding public float slopeLimit Character Controller public CharacterController controller void Start() controller GetComponent lt CharacterController gt () void Update() Check if the player is colliding with anything (Character Controller) if (controller.collisionFlags CollisionFlags.None) isColliding false else isColliding true Check if the player is standing on the ground if (isColliding amp amp groundNormal ! Vector3.zero) onGround true else onGround false void OnControllerColliderHit(ControllerColliderHit hit) Check for floor if (Vector3.Angle(transform.up, hit.normal) lt slopeLimit) Store floor object data ground hit.gameObject Store ground surface normal groundNormal Vector3.Normalize(hit.normal) else reset variables ground null groundNormal Vector3.zero slopeLimit is a static value. Additionally, getting the ground object isn't actually necessary atm, but I plan on using it later. Edit Currently I'm using controller.collisionFlags to detect when the player is colliding with something and haven't been able to find a similar alternative. Setting the isColliding bool to true using Rigidbody.OnCollisionStay would be simple, but setting it to false without use of another void function seems difficult. is that possible at all? |

0 | How to stop the Unity Editor from continuously rendering? Look closely at the image below. Even though the game is not running the scene shows that green wheel is spinning. This means the scene is being rendered constantly and my battery is dying. I know Unity used to not do this and was in fact one of the reasons I liked Unity over some other engine that defaulted to always running and would make my laptop fans start up even when just sitting idle in the editor. Is there any way to get Unity to render on demand. Meaning, only render when I interact with it, when I move the camera or change a setting like it used it? I saw in preferences there's an "interaction mode" setting but the best it can be set to is don't render faster than 30fps. That's not useful. Is there some other setting to get the editor to only render when interacted with? |

0 | Distinguish between HTC Vive controller grip buttons in Unity In Unity, I can check for grip button presses via the SteamVR API like so if(controller.GetPressDown(SteamVR Controller.ButtonMask.Grip)) ...

For Unity's Input API the documentation states 1 The grip trigger differs between platforms The HTC Vive controllers each have two grip buttons but both map to the same axis. The value for these buttons is 0.0 when not pressed and 1.0 when pressed (intermediate values between 0.0 and 1.0 are not possible).

Is there any way in Unity to check which one of the grip buttons of a HTC Vive controller is pressed? |
0 | Rotating a gameobject in the Inspector doesn't change direction When I add a Cube to a scene, the blue axis ( forward) of the cube points into a certain direction. When I now change the Y rotation of the cube to 90 in the inspector, the blue arrow doesn't rotate. I would have expected it to rotate with the rotation that I have defined for the cube. What is happening here? To explain more in detail why this is bothering confusing me I want to rebuild the RE4 inventory (which is actual 3D). The items in this inventory can be moved within the "grid" To do that I have created a suitcase and then I added a gun to it As one can see, I have assigned the facing direction properly The blue axis ( forward) points into the direction of the gun. Now I wanted to rotate the gun in such a way that it is shown like in the original RE4 inventory. To do that, I apply a rotation of Y 90. The gun looks correctly now However, the blue axis now faces the wrong direction in my opinion. Why does it not rotate along with the rotation of the gameobject? This really confuses me because now when I want to move the gun left or right, I have to change its X position value instead of changing the Z position value. This just seems wrong to me. Can somebody tell me what I'm missing here? Thank you. |

0 | How to run a long task without freezing my game? I have a component that is in charge of generating a level at runtime, and this is an operation that takes quite some time. As a consequence, I experience a hang when this operation is executed (when the scene is loaded). This problem can be summarized to the fact that SceneManager.LoadSceneAsync in fact is not async at all in its second phase, when it initializes all the objects. There are three approaches I have searched for and thought about Slicing the operation as explained on this video This is non trivial, I would have to rewrite chunks of code for the sake of avoiding a few seconds hiccup at scene load. Furthermore, the person explaining in the video says that they changed Unity source code which I don't have access to. Running the operation in a background thread This is definitely interesting, it would require minimal changes. The only problem is that at some point I have to create Unity objects (GameObject, Mesh etc) and this is not possible when outside Unity thread. I was thinking more or less of this code to be run on the background thread class Builder public void Build() 1. do something long 2. create Unity object with result from 1 something like that await RunInUnitySynchronizationContext(() gt new GameObject(...)) 3. do extra stuff on the result of 2 The thing is I have no idea at all on how that second step should be written, if possible at all. Use a non animated Loading screen and wait for it to finish This is the simplest and effectively does away with the problem by 'just' hiding it. Question What's an effective approach to solve this problem? |

0 | How to make rhythm game long notes in Unity? I'm making a rhythm game for a university course and I can't figure out a way to make the long sustained notes. For reference, this is what I mean taken from Guitar Hero I already have a system working for regular notes. The way I do it is that the notes are stored in an external file as numbers which represent the absence or presence of a note as well as what type of note it is, separated into musical bars 000 010 020 001 There are three lanes for the notes to be, and this means that in this particular bar there are notes wherever it's not 0 (with the numbers being different types of notes). I had thought of using this system to create long sustained note start and end markers (say 3 and 4) and that create another game object which would be the line between the start and end markers. But the way my note generator works is that the notes are not all generated at once because that'd be pretty heavy. Instead, the notes are generated at a certain time taking into account its speed so that it's instantiated and will reach the player's activator when it's supposed to. The following is a part of my note generator code, put in the Update method if current song time time offset is greater than time taken for all executed bars so far spawn the next bar's notes if (songTimer timeOffset gt (barExecutedTime barTime)) StartCoroutine(PlaceBar(noteData.bars barCount )) barExecutedTime barTime And here is the PlaceBar coroutine go through all notes in a bar creates an instance of note prefab depending on which note is meant to be spawned private IEnumerator PlaceBar(List lt SongParser.Notes gt bar) for (int i 0 i lt bar.Count i ) if (IsThereNote(bar i .bottom)) GameObject obj (GameObject) Instantiate(GetNotePrefab(bar i .bottom, true), new Vector3(bottomLane.transform.position.x distance, bottomLane.transform.position.y, bottomLane.transform.position.z 0.3f), Quaternion.identity) if (bar i .middle ! 0) GameObject obj (GameObject) Instantiate(GetNotePrefab(bar i .middle, false), new Vector3(middleLane.transform.position.x distance, middleLane.transform.position.y, middleLane.transform.position.z 0.3f), Quaternion.identity) if (bar i .top ! 0) GameObject obj (GameObject) Instantiate(GetNotePrefab(bar i .top, true), new Vector3(topLane.transform.position.x distance, topLane.transform.position.y, topLane.transform.position.z 0.3f), Quaternion.identity) yield return new WaitForSeconds((barTime bar.Count) Time.deltaTime) So if I were to make start and end markers, the start marker would not know where the end marker is because it doesn't exist. Could anyone help please? |

0 | Unity protect MonoBehaviour derived classes from instantiating via new in C When the class hierarchy grows and you deal with a lot of custom types in your project, it sometimes becomes hard to remember which types are allowed to be created via new and which types are derived from MonoBehaviour and therefore can't be created via new but must instead be attached to the GameObject as a Component. Is it possible to have some safety mechanism for this? The goal would be to have two base classes to control the ability to use new on a certain type. Ideally resulting in a compile time error instead of an easy to miss warning in the console ("You are trying to create a MonoBehaviour using the 'new' keyword. This is not allowed. Blah blah."). My attempt to make the constructor protected, like this public class UnCreatableBase MonoBehaviour protected UnCreatableBase() using new should be not allowed public static T Create lt T gt () instead this method allows object creation return GameObject.Instantiate (Resources.Load ("Prefabs " typeof(T).Name) as GameObject).GetComponent lt T gt () public class CreatableBase public CreatableBase() new is ok here still allows me to write var whyDoesThisWork new UnCreatableBase() I can access the protected constructor even from an outside scope. Now, the obvious solution would be to make constructors of MonoBehaviour derived classes private. Manually. All of them. Manually. I was wondering if there's a way of achieving the same in a more generic way. |

0 | How to "merge" multiple intersecting circles so that only the outer edges of each show? In my RTS (In Unity) each unit or building has strategic circles in a similar fashion to SupCom. If you have multiple units or buildings selected it looks like the picture to the left. I want to make it look like the picture to the right, where anything inside the outer edges of their circles is no longer shown. I draw these using vectrosity, mentioning this just in case vectrosity provides a way of doing this, or can be modified to do this. The circles are essentially just an array of points with lines drawn in between them. How would I go about "merging" the circles inside of their overlapping area? This is similar to How to make unit selection circles merge?, however I am not interested in a shader solution. Edit To re explain the above. I'm not seeing how the answers are applicable. I've read through the other thread before posting, which is why I posted it here to avoid this exact thing (being marked as a duplicate). I have an array of points with straight lines in between them to create a circle like effect. This is not a true circle, but a really granular polygon. I am interested in solutions that are achievable in C within Unity, not with shaders or with rendering mechanics. Edit2 Another picture based on one of Roberts suggestions This seems viable, though computationally expensive. If I have a circle made up of 250 points, and 50 circles all intertwined that's 615,500 checks in a worst case scenario. |

Do I have something wrong in my importing order or is something missing? I tried to refresh or reload the asset in the AssetDatabase but that didn't worked. The OnImportAsset method looks like the following. I implemented the ISpriteEditorDataProvider to support the sprite editor. public override void OnImportAsset(AssetImportContext ctx) name GetFileName(assetPath) aseFile ReadAseFile(assetPath) GenerateAtlasTexture() if (spriteImportData null spriteImportData.Length 0) SetSingleSpriteImportData() GenerateTexture(ctx.assetPath) ctx.AddObjectToAsset("Texture", texture) ctx.SetMainObject(texture) foreach (Sprite sprite in sprites) ctx.AddObjectToAsset(sprite.name, sprite) With the GenerateAtlasTexture method I create a sprite atlas out of the aseprite file. I had to create my own SpriteImportData class because Unitys struct won't get stored through the serialization process and I have to store the import settings of each sprite in a way. The GenerateTexture method uses Unitys own TextureGenerator class to generate the textures or sprites and store them in a instance variable called sprites. Here is the link to the repo. It is currently in the "sprite editor" branch. https github.com martinhodler unity aseprite importer tree sprite editor Thanks a lot |
0 | Upon import, isosphere is missing To build my tank for a Unity game, I am using Blender. Currently, I am making a turret consisting of an isosphere with half of the faces removed (I needed the bottom to be "flat") with some minor visual edits, two cylinders (one is the hatch, the other the antenna), and a cube to act as a hinge The inside is hollow. When I imported it to Unity (drag and drop from File Explorer straight to Unity Assets folder), the entire isosphere was missing as you can see from the preview I have tried to correct the normals with CTRL N as mentioned in other Blender forum pages but it still doesn't work. How exactly do I make my isosphere appear in Unity? NOTE This works if imported as a .fbx file but I would much prefer the file to be a .blend file instead (which is default). |
