0 | Character falls through the Platform Effector 2D in Unity. How can I fix it? Character falls through the Platform Effector 2D in Unity. How can I fix it? Here is the demonstration https imgur.com G5YkTxa. I tried changing the Edit Project Settings... Physics 2D Default Contact Offset from the current 0.01 value to the 0.1 value. The result is the same and here is the demonstration of it https imgur.com 3TAOsNY. Here are my settings for the platform Here are my settings for the character's RigidBody 2D Here is what character colliders look like when my character runs https imgur.com CTialU3. I basically run the recorded inside Unity animation of running and move my character with the help of the private void FixedUpdate() ... some code which computes the velocity vector depending on the input (the pressed buttons) characterRigidBody2D.velocity velocityVector I googled for a while now similar issues, but was not able to find a solution. I want to avoid the character falling down randomly during running. |
0 | How to implement the swipe up and down number select Unity3d I want to implement the UI like in the image. I want the users to select the number by swiping up and down. I found the tutorial on the YouTube which is similar to the what i wanted (https www.youtube.com watch?v mL FLsV3WRs) But it shows only the numbers from 0 to 9. I want to show from 1 to N (n can be any number). Any idea to help me to get this would be great. |
0 | Why is there a discrepancy between these two transform.up vectors? I was trying to implement a feature which required transform.up, the result didn't match the green axis gizmo displayed in the editor so I assumed it was being put off by the rotation of the object despite expecting the gizmo to adapt to that. I then modified the prefab such that everything was now child to an empty object and the secondary objects were child to that instead of the rotating model, and wrote a script that simply copies the transform so that it tracks. This still didn't show the values expected from what the gizmo in the editor showed. I then did a Debug.LogError in the track script and this time the result was as expected. Why is transform.up showing the value expected from the local y axis gizmo but when passing a reference to the original script and checking tracked.transform.up gives off results? To reproduce in a simpler environment I set up a simple test scene. Simple default cube with the hierarchy structure shown in the screenshot. The transform values are as follows parent zeroed x 0, y 90, z 0 for cube x 0, y 90, z 90 for TrackPoint Scripts are as follows test.cs attached to trackpoint private void Update() Debug.LogError(transform.up) Track.cs attached to tracker public Transform transformToTrack private void Update() transform.position transformToTrack.position transform.rotation transformToTrack.rotation Debug.LogError(transform.up) byref.cs attached to cube public GameObject refObj private void Update() Debug.LogError(refObj.transform.up) When run, if you clear the console then click pause you'll see that one of them differs from the others. I don't understand why. My project and this sample scene differ in which it is that is giving unexpected results but the results are inconsistent with what I would expect. But wouldn't they all give the same result? |

0 | Achieving 2D Lighting for Terraria Like Game I'm trying to achieve the fog of war lighting style that Terraria and Starbound have. Terraria's lighting system seems to be more blocky tile based, but Starbound's is a lot more smooth. The Desired Effect Starbound is using a shader to render its lighting, but how it's going about that is quite a mystery to me. The idea I had on how to achieve the desired effect is the following Create a texture that is black and somehow calculate the area that is white, storing this in a light map render texture, finally doing an Additive Blend of both the main texture and the light map texture to achieve a similar effect to Starbound's. (However this does not take into account lights in the world, which I also have absolutely no clue how to include in my calculation to the light map render texture) I say somehow in italics because I have no clue as to how I can create this "Mask" effect in the light map render texture. How I can do calculations necessary to create the mask is beyond me I don't even know how I can begin to translate the game world's data, relative to the what the camera sees, and update the texture accordingly. TLDR How can I achieve lighting similar to that of either Terraria or Starbound in Unity 2D? |
0 | Can we merge multiple FBX files, using Maya, and export as a single FBX file? I have a humanoid model which is made up of four FBX files one is for the human, one is for the T shirt, one is for the pants and one is for the hair. I want to merge them into one FBX, because the manner in which I am using it requires using a single FBX file to represent the character. Can we merge four FBX files into one, using Maya, and export as a single FBX file? |
0 | How to avoid game starting before start button is clicked? I've made a game with a Title Screen (Canvas), and a Start Button attached to the Title Screen. Points, GameOver, Restart, and even the Start Button sort of works, but it's possible to play the game before the user presses start. Is there a way to make the GameObjects only appear after the button is clicked? I've tried to move and change the "public void StartGame()", but I can't get it right.

0 | Counting triangles and vertices in Unity's cube I want to understand logic behind drawing triangles of primitives in Unity. When we spawn simple cube, variable mesh.vertexCount gives us value 24. Also when we list all vertices positions (from mesh.vertices) and triangles numbers (from mesh.triangles), we get 0. (1.0, 1.0, 1.0) 0 1. ( 1.0, 1.0, 1.0) 2 2. (1.0, 1.0, 1.0) 3 3.

0 | Profiling unity games on Android devices I would like to profile our Unity mobile game on Android devices in a way similar to profiling Unity games on iOS with Instruments. I am aware of how to do this using Unity's profiler, I would however like to use a third party profiler for the following reasons to validate Unity's profiling data to have more visibility into how the app is running, including Unity's functions, etc. the largest lag spikes cause unity's profiler to run out of samples. I'm however very interested in precisely these spikes I'd like to have profile data for longer periods than unity records for I'd like to do analysis over time (not just detailed data for each frame, but also aggregated over a time span) Essentially I'd like as much visibility as possible to make Android on device profiling as comprehensive as possible. As close to Instruments on iOS as possible. So far I've tried with DDMS, but could only get visibility into Andoid OS functions and seeminly nothing in the actual apk at least nothing I recognised. I tried with mono2x and il2cpp, with all debug features that I'm aware of in build and player settings enabled. The game is developed with Unity 5,4 with Mono2x. All help is appreciated. I've listed my intents above, so even if profiling on device is not possible in this way on Andoid, alternate solutions to the listed intents are still very appreciated. Thanks! |

0 | Top Down 2D Collision C I know this has been asked before, but I don't understand why my code isn't working. I'm doing top down collision with no gravity.

0 | How do I include a blend tree in my controller? I want my player to aim up and down with a pistol. I have stored an quot aim up quot pose in one anim file, and I have stored an quot aim down quot pose in another anim file. I want to blend between these 2 poses according to the mouse pointer on the screen If the mouse pointer is at the bottom of the screen, the blend tree should only play the quot aim down quot pose If the mouse pointer is at the top of the screen, the blend tree should only play the quot aim up quot pose If the mouse pointer is at the middle of the screen, the blend tree should play a 50 50 mix of the quot aim down quot and of the quot aim up quot pose To do that, I have added a 1D blend tree to my animator. It looks like this I have tested the blend tree. When I scrub through the quot timeline quot using the red line, it works as expected Now I wanted to test it out in my game, but I don't see how to set the blend weight of this 1D blend tree. The docs say that the blend tree is controlled by the animation parameters. As far as I can see, Unity automatically created one for me when I added the blend tree. The name seems to be quot Blend quot , as can be seen in the screenshot The following however has no visual effect for me animator.SetFloat( quot Blend quot , 1f) To check if this parameter even exists, I have changed its value to 0.3 in the animator. Then in my code, I check the value like this, and it does return 0.3 float fCur animator.GetFloat( quot Blend quot ) So this is proof that the parameter does exist. However, when I set a new value like... animator.SetFloat( quot Blend quot , 0.56f) ... then this value is accepted, but it doesn't have any visual effect, and it doesn't show in the animator's paramters. Can anybody tell me how I could achieve what I want? Edit I have tested it in a new, stripped down project. In this new project, I have the blend tree as the default state in the animator, and everything works. So the fact that my blend tree is NOT the default state in the other project seems to be the problem. This is what it looks like I will first try to investigate more on this. |

0 | How to find the minimum number in a float array C Unity i have a for loop that detects the position of every game object in a list and gets the difference between that object and an object anchored in the center and then stores all values in a float array. what should happen next is find the minimum distance in that array and make that object (the object with the smallest distance) move towards the anchored center. the problem is that no matter what i do, it always gets the maximum number (which is the furthest game object). here is what i have so far public RectTransform panal public GameObject characters public RectTransform center private float distance private float minDistance private bool isDragging false private int distanceBetweenCharacters private int minCharNum private void Start() int charLength characters.Length center GameObject.Find("CenterCompare").GetComponent lt RectTransform gt () distanceBetweenCharacters 200 private void Update() for (int i 0 i lt characters.Length i ) distance i Mathf.Abs(characters i .transform.position.y center.transform.position.y) float minDistance Mathf.Min(distance) Debug.Log(minDistance) for (int a 0 a lt characters.Length a ) if (minDistance distance a ) minCharNum a Debug.Log(minCharNum) if (!isDragging) LerpToChar(minCharNum distanceBetweenCharacters) void LerpToChar(int position) float newY Mathf.Lerp(panal.anchoredPosition.y, position, Time.deltaTime 5f) Vector2 newPosition new Vector2( 386, newY) panal.anchoredPosition newPosition public void StartDrag() isDragging true public void EndDrag() isDragging false I assume that the problem is with the array because when i set the minCharNum to a specific integer, it works just fine.

0 | Unity Remote 4 on Galaxy S5 won't connect to Unity 5 I'm having some trouble connecting Unity Remote 4 to Unity 5. I'm using a Samsung Galaxy S5. I've searched a bit and the other solutions with other phones aren't working for me. What I've tried so far I installed the Android SDK by using Android Studio. I'm not sure if that's part of the problem but either way. I installed the Google USB Driver, the 5.0 (API 21) and 5.1 (API 22) SDKs. My phone is running on Android 5.0. All the SDK tools (Platform tools and build tools) are installed. I set USB Debugging, Stay Awake and Allow Mock Locations in the Developer Options on my phone. I set the Android SDK path in Unity (Program Files Android android sdk) I set, in the Unity Editor Settings, Device to Any Android Device. I made sure my computer sees my phone, which it does. And I tried to open Unity first then the Unity Remote and Unity Remote first then Unity Engine. And set Android as my Platform in Build Settings. And I've tried plugging my phone in a USB 2.0 and a USB 3.0. All that and each time I press the play button nothing happens in the phone. I have no idea what I'm doing wrong. I tried using Unity 4 and Unity 5. If my OS is a factor, I'm using Windows 7 Ultimate, 64 bit. If the following information is needed Hardware Version G900P.04 Model number SM G900P Android version 5.0 Kernal version 3.4.0 If any other information is needed I will provide it. Anyone have a solution to my problem? Thank you. |
0 | Unity ScrollRect many objects perfomance issue I have scrollrect setup and over 1000 objects to scroll through. Currently i'm Instantiating all the 1000 objects at once and notice fps drop.

0 | Nestling into contact with a group of physics objects without exerting forces on them I'm making a pool game, and would like the circle (imaginary) to be in contact with the table and balls, and to fit perfectly as a ball would. Now I thought I would use Rigidbody and lerp the position of the circle to the raycast hit, and its collider it would force it into a fitting position. The problem I encountered is that since it has a collider, it also pushes the balls, which I do not want. So my question is, how do I make an object act like it's touching amp blocked by other GameObjects with Colliders and Rigidbodies, without pushing them? |
0 | Get random point on NavMesh async I am trying to spawn some entities on a navmesh at runtime. The entities need to spawn at a random point.

How can i make this piece of code run in the background until there is an actual value returned. Cause this holds up the main thread till a value is obtained. |

0 | How to calculate a normalized direction of two rotations? In Vector math and translations we can do dir (v1 v2).norm and then v1.translate(dir 50) so v1 moves to the v2's direction. What about rotation and eulerAngles? Here's my attempt, but it doesn't work, probably from some obvious reasons. Vector3 initial ob1.transform.rotation.eulerAngles get it's initial rotation ob1.Rotate(new Vector3(0,0,90)) rotate Vector3 after ob1.transform.rotation.eulerAngles store new rotation ob1.Rotate(new Vector3(0,0, 90)) rotate back to initial here I need to calculate the direction so I can do rotate(dir 50) or something similar I need to get the rotation direction, so I can rotate the object continously with direction, not with a fixed desired angle value. To be super clear, I need to get this blue line direction The object is initially rotated by (0,0,57). I need to rotate it around it's center (green axis). I know I can do logo1.transform.RotateAround(logo1.transform.position, logo1.transform.up, 80) and it works, but I need the direction from this, so I can use it in Tweening. |
0 | Character controller falling with positive speed I'm having very weird problems with my player's vertical movement. I'm using a Character Controller component with a capsule collider and no rigidbody. For testing purposes, I've ended reducing my jump script to just this line owner.CharacterController.Move(new Vector3(0, 0.01f, 0)) When executing this script, the player should just fly upwards at a constant speed, right? Well, what ends up happening is that the player starts jumping in place repeatedly. The jumps are smooth, as if the movement was being affected by gravity. I thought that the standard Character Controller doesn't handle gravity automatically and you have to do it yourself, so I can't understand what's going on here. There is no other code affecting the player, if I comment that line it just rests in place. If I try a different direction (like (0.01f, 0, 0)) the player moves in a straight line in the provided direction as expected. But when moving vertically, weird stuff happens S |

0 | Shooting the closest enemy that you can see I'm trying to make my main character aim at the closest enemy that he can see. My issue is with the close range criterion taking priority. If the enemy is near the player but the player can't see him, I'd like the player to look for another enemy inside his range. As you can see in the image, There is an enemy behind the wall. The player is not aiming at him because he can't see him. So far this is correct. But the player is also ignoring the enemy in front of him because he's busy rejecting the one behind the wall.

0 | Unity Editor stops updating ScriptableObjects if I click away from them in editor I'm trying to be better about structuring my code, and I think I'm doing it right. The issue I've got right now is I need to get joystick inputs, scale those values appropriately, and then use that scaled data on any number of MonoBehaviour scripts. I'm trying to split the input conditioning from the end user, and I'd like to do that by using a ScriptableObject to hold the conditioned data. I was thinking that a MonoBehaviour script would run, get the joystick data, scale it, and then push that data to variables in the ScaledJoystickData ScriptableObject. Later, a second MonoBehaviour script would access the variables in the ScaledJoystickData and use those to move the things in the game. I'm understanding the benefits of structuring the code this way, especially in that I can access the ScriptableObject from the editor and manipulate those values I don't actually need to have a joystick connected, and I'm free to test either end of the input handling independently. The problem is that, if I am looking at the ScriptableObject instance in the editor, it stops updating as soon as I click away from it (to the consuming GameObject). If I click back to the ScriptableObejct instance, none of the values update. Nothing on the GameObject's script updates unless I start the game with that GO selected in editor, and again THAT fails to update if I click off and click back. The GameObject script is currently using the values from the ScriptableObject instance and piping them to public variables, and the public variables aren't updating. Is there some bug with ScriptableObjects, or am I doing this wrong? EDIT Here's an example. Make a script called "ExampleSO" and replace the contents with using System.Collections using System.Collections.Generic using UnityEngine CreateAssetMenu public class ExampleSO ScriptableObject public float stashedVar 0f Make a script called "ExampleWriter" and replace the contents with using System.Collections using System.Collections.Generic using UnityEngine public class ExampleWriter MonoBehaviour public float scaling 2f public float scaledInput 0f public ExampleSO exampleSO null Update is called once per frame void Update() if(exampleSO! null) scaledInput scaling (Input.GetKey(KeyCode.LeftArrow) ? 1f 0f) exampleSO.stashedVar scaledInput Make a script called "ExampleReader" and replace the contents with using System.Collections using System.Collections.Generic using UnityEngine public class ExampleReader MonoBehaviour public float display 0f public ExampleSO exampleSO null void Update() if(exampleSO! null) display exampleSO.stashedVar Create an instance of the ExampleSO, add the ExampleWriter to a game object, and put the ExampleSO instance into the ExampleWriter slot. Highlight the game object holding ExampleWriter and run it. Push the left arrow key and see the value toggle 0 2. Click the ExampleSO instance. Nothing is happening there now. Click back on the game object, and now it doesn't update either. If you have the ExampleReader on the same game object then it won't work at all. ExampleReader will read fine, if you have it on a separate GameObject, but again if you click off and click back then it stops responding. |

For now, I have something like void Update() target firstCircle here I need to perform some calculations this.transform.RotateAround(target.transform.position, Vector3.forward, speed Time.deltaTime) As you can see in the code, it rotates around the upper circle now. I need to switch the target variable to the secondCircle when the player comes back to it's initial position (or is near it). I came up with something like if(Mathf.Abs(Mathf.DeltaAngle(360f,this.transform.rotation.eulerAngles.z)) lt 5f) change target and it works but has two issues. First the epsilon value. If I set it to 5f the above if is true like 7 times (depending on the player's speed). Of course I could make a lock to run it only once per cycle, but there's a second problem. If the object is moving too fast, the if will be false each time, cause the speed step is always higher than the epsilon. How is this done in 'gravity' games like AngryBirds when the bullet changes it's attraction point? |

0 | Function Not Storing New Value of Variables? I'm currently building a small scope RPG and running into an issue with modifying variables. My goal is to alter my character's stats when I run a procedure to change their equipment. My code is as follows public class Player MonoBehaviour Base stat variables public static int PAtk 12 public static int PDef 6 Battle exclusive stats. Will have equipment added onto them. public static int Attack PAtk public static int Defense PDef Equipment variables. public string weapon public string armor private void Awake() Get equipment EquipWeapon( quot Bronze Sword quot ) EquipArmor( quot Bronze Armor quot ) void EquipWeapon(string WeaponName) weapon WeaponName EquipmentManager.GetComponent lt Equipment gt ().EquipStatIncrease(PAtk, Attack, PDef, Defense, WeaponName) void EquipArmor(string ArmorName) armor ArmorName EquipmentManager.GetComponent lt Equipment gt ().EquipStatIncrease(PAtk, Attack, PDef, Defense, ArmorName) public class Equipment MonoBehaviour Create dictionary to give each weapon a key ID. This will be used for calling items in another array. Dictionary lt string, int gt WeaponDictionary new Dictionary lt string, int gt () Create weapon array for stats. public int , WeaponStats Start is called before the first frame update void Awake() Declare weapon IDs WeaponDictionary.Add( quot Bronze Sword quot , 0) WeaponDictionary.Add( quot Bronze Armor quot , 1) Declare stat array Table ID, Atk, Def WeaponStats new int , 0,4,0 , 1,0,4 public void EquipStatIncrease(int BaseAtk, int BattleAtk, int BaseDef, int BattleDef, string Equipment) BattleAtk BaseAtk WeaponStats WeaponDictionary Equipment , 1 Debug.Log(BattleAtk quot Battle Power quot ) BattleDef BaseDef WeaponStats WeaponDictionary Equipment , 2 Debug.Log(BattleDef quot Battle Defense quot ) The general gist of it is once EquipWeapon or EquipArmor is ran, the equipment variables in the Player class will be updated. Afterwards, another function in the Equipment class will be ran with variables from the Player class passed over, in order to be modified by the WeaponStats array. The Debug logs in EquipStatIncrease show me that I am getting the desired results. However, the Attack parameter that is being placed into the function is not being permanently modified. During the first execution of the EquipStatIncrease method, I will get a result of 16 BattleAtk and 6 BattleDef, due to the weapon being equipped. However, once it's run a second time to equip the armor, I'm shown a result of 12 BattleAtk and 10 BattleDef, even though BattleAtk should have stayed at 16. This leads me to believe that the variables I'm trying to transform are not being modified, and I'm not sure what to do about this. In the EquipStatIncrease parameters, BattleAtk gives the message Parameter 'BattleAtk' can be removed if it is not part of a shipped public API its initial value is never used However, I don't know what action to take to resolve this. I'm aware of being able to use an int function instead of void, but unless I'm missing something, that only works if I'm trying to change one variable. If I want to have an equipment object that affects 2 different stats at once(ex. a weapon that increases BattleAtk and BattleDef), then I don't see how an int function would work. |

0 | Selecting Dictionary item based on custom classes instead of keys I am attempting to write my own path finding code for a game I'm working on that will implement a form of the A algorithm.

At one point I need to test the dictionary and return from it the node with the lowest "f" value. I came across the morelinq MinBy function with seemed promising, but so far have not had any luck getting it to work.

I need a way to return the Dictionary item with the smallest "F" value, this would be pretty easy if it were an integer but the F value resides in the Node class. I don't have to use MoreLinq, I would be happy to do it any other way that someone can come up with. Cheers! One more note the code above is incomplete in an effort to minimize it down to only what is necessary to understand the problem more complete code can be provided if necessary. |

I want to change Tile's sprite during runtime, but it doesn't render. class SwitchableTile Tile usable sprites public Sprite sprites index to the sprite private int spriteIndex 0 I don't know when it's called but set sprite to current spriteIndex public override void GetTileData(Vector3Int position, ITilemap tilemap, ref TileData tileData) .. if (sprites ! null amp amp sprites.Length gt 0) tileData.sprite sprites spriteIndex called per Tilemap.RefreshTile public override void RefreshTile(Vector3Int position, ITilemap tilemap) tilemap.RefreshTile(position) Also tried to refresh the tile according to the position in MonoBehaviour BoundsInt bounds tilemap.cellBounds bool updated false foreach (Vector3Int pos in bounds.allPositionsWithin) TileBase tile tilemap.GetTile(pos) if (tile amp amp tile is SwitchableTile) if (!updated) just loop index Sprite sprite ((SwitchableTile)tile).GetNextSprite() set sprite ((SwitchableTile)tile).sprite sprite updated true refresh tilemap.RefreshTile(pos) Since Tilemap.RefreshTile calls TileBase.RefreshTile per refresh, the problem's solved after I implemented TileBase.RefreshTile. I'm not using 2d extra's animation tile because I want to change sprites only under certain condition. Also not using Tilemap.SwapTile because in this case I'm solving it using customized Tile, instead of creating a new Tile. Update Well...It proves that I need to implement RefreshTile for a Tile. Now the sprite refreshes. But I'm still not sure about GetTileData, do I need to implement it? When it is called? |
0 | What should I set my managed stripping level to? I know the higher the Managed Stripping Level the smaller binary size but I also know the higher the level more issues you can run into so I have some questions about all this. If I set my managed stripping level to high will I see the effect of that and be able to properly test it when running my game in the editor or would I have to compile to make sure everything runs alright? Can issues with a high managed stripping level be platform specific (Meaning a high level is good on one platform but causes issues on another)? Does managed stripping level only effect binary size or can it also effect performance? If it can effect performance would a binary with a high managed stripping level run faster than a binary with a low managed stripping level or would it be the other way around? |
0 | how to implement ARVR controller in unity vuforia hello i've been strugling figuring out this thing. i'm trying to make ar controller for my vr cardboard game, so the idea is using AR and VR simultaniously. you will completely in vr game but your phone camera wil be turned on and set to AR mode. while you're in vr mode and your AR camera will detect your marker and repositioned it based on your view and the distance between camera and object. that marker will appear in your vr game and you'll make it as a controller. then maybe you want to make that marker appear as a gun, a sword, a shield or whatever it is that can be work with this concept or maybe you just can watch it to get the idea if my explanation is not clear enough https www.youtube.com watch?v a v a23u6n0 so i'm trying to implement it with vuforia as it's augmented reality API and of course Unity. now i'm on the stage where i already now how to use AR amp VR simultaniously and how to transtition between AR to VR or otherwise. i'm still strugling on how to re potitioning my marker to correct position in my VR world. i already tried asking this in vuforia forum but there's still no answer until now. if you guys can help me with this it would be a big help !! thx before |

0 | Constructing a building in the "Past" scene, and finding a different version of it in the "Future" scene I am trying to create a game where one scene would be the quot Past quot and one scene would be the quot Future quot . The player can travel through a portal to move between the past and future scenes. In the past scene, the player makes a wooden house and in the future scene it will be turned into something else. There can be multiple instances of these buildings in different places in the scene. So far, I've tried... Using DontDestroyOnLoad to carry the object through from the past to future when loading between scenes. Using singletons to avoid duplicating the object multiple times when loading back and forth. But that has a problem using singletons causes restricts me to just one instance of the building per scene, and I want to have several. The reason why I wouldn't want to unload the old object when the scene unloads is because I wanted the player to be able to build in any area available within the scene. Something like the Fallout 4 building mechanics, where you can build in certain areas and keep those buildings, but I want it to become a different prefab in the future scene. How can I implement a feature like this? |

0 | Third Person Flying Camera I am having issues creating a third person camera for my Rogue Squadron (N64) like game. First I have posted my issue on the official Unity Answers site here. So far my ship is behaving as I want and the camera follows position correctly (XYZ), however, it doesn't rotate how I would like. My first attempt was to set the rotation of the camera to the rotation of the ship and realized that is not what I am looking for either. I have found some information on rotating around a (pivot) point but I am having trouble understanding them. For example, I have found this and this but Im not sure how they work. The end result would be something like the camera found here. Thank you for any help, I would greatly appreciate a description of what you are doing how it works. Lastly this is done in C in Unity. I can provide my code if needed. |
0 | Unity 2D Graphics Optimization For Mobile Devices I want some advices on how to create graphical assets for mobile devices so that the game will have a good performance and not lag on mobile devices. I had 3 issues with my games and that is they all lag after playing a little while, some lag more some less but they all lag, I think the problem is in the graphical assets. Some of the games were simple as flappy bird with a couple of images in the project but the game was lagging after playing it for a minute or two. Now my question is, how to create graphical assets, do I need to export them on 16bit or 32bit and what is the difference, which options should I set in unity, compressed, true color, 16 bit? And are there some other options that I can check or uncheck in unity so that the graphics will perform better on my game? When I pack my assets in a sprite sheet, should I put them on larger sprite sheets for example 2048x2048(which is one of the options for max size in unity) or should I pack them on smaller sprite sheets? Does a sprite sheet have to be to the power of two e.g 1024x1024 or 512x512 or I can pack my assets until they fit and the size does not matter for example the sprite sheet can be 640x410 or something like that, not on the power of two? Does it make a difference when there is free space in a sprite sheet does that affect graphic performance or do I need to squeeze the sprites closer to each other so that there will be no empty space in the sprite sheet? Please answer the question that I'm asking, last time I posted the same question people started asking me about the game, did I do this or that and my question then went off topic and got closed, the game is not the question, the question is everything that I mentioned above or if you have something to add that will help me. If you can help me about this then please answer, and again please don't ask about the game and did I do this or that in the game. I hope that my question is clear, and that it is not off topic. |

0 | Can you use a standard multi thread if only reading unity objects? First of all I know about coroutines and how to use them (they're awesome). A friend of mine was telling me about the way the he implemented his saving system in a game he was working on, after asking him what he was using I found out that he is using system.threading and not coroutines to save data. I know that Unity isn't thread safe but apparently he has had no issues with saving which leads me to wonder if it is ok to use normal threads as long as you're only reading data and no pre existing data is modified in the gameworld? would this affect the game at all (other than some moving objects being slightly ahead of where they should be because of the time it took to get to that object and save it)? |
0 | How to align 2 IMUs' quaternions? Suppose I have 2 IMUs that output 2 quaternions. I place one IMU on my left hand and another one on my right hand. I put both my hands flat on the table and point it forward to the same direction. What I expect is that they should give very similar quaternion. But it turns out that the IMUs reading differs about 10 20 degrees around the Y axis when plotted in Unity3D. This means I cannot just apply the quaternion to the hand model inside Unity directly. I need to know the exact offset of this 10 20 degrees error in order to make the hand model point in the same direction. How do I figure out this offset automatically? Or is there another way that I can align both IMUs? How do people deal with this IMU problem? PS. Putting the IMU on the hand is just an example. I can put them both directly on the table near each other and they still give slightly different quaternions. |
0 | Mouse input position is being printed as Unity coordinates, but the actual coordinates used seem incorrect This will be hard to explain, but I'll try to keep it short and simple I'm trying to set the position of a UI rectangle to the position of the mouse when clicked. When initialized, the position of the rectangle works fine (if, during Awake(), I initially set it so that x 100 and y 100 and then check the Rect Transform component during run time, Pos X and Pos Y are both set to 100 as intended). However, if I use the X and Y coordinates of Input.mousePosition, Pos X and Pos Y are given strange numbers that I have no clue where they're coming from. I don't think they're pixel coordinates because the value for Pos X of the rectangle when my mouse clicks at the farthest left possible during run time is a value over 300 when it should be 0, and that value goes up as I progressively click rightwards. Now here's the strange bit. When I try to use print() to print the mouse position x and y values that I use to set the rectangle's position, they're printed as intended (clicking the bottom left of the game area yields x 0 and y 0) yet the rectangle's position is far from close the values printed (rectangle's position is x 337.5 and y 192.5). Can someone please explain why this happens, and how I can fix it? I suppose I can manually fix it by subtracting the new position values by 337.5 for x and 162.5, but it feels too brute force ish and there's bound to be consequences down the line.

0 | How to create a re usable layout of text fields that can be bound to in world space? Current tools Unity 2020.3.2f1 (Win10) UI Builder preview package My end goal is to do the following At varying intervals, change values for many data objects in the background, such as prices, resources, demand, supply, etc. Display those values in a flat table list (as they change) in world space to the player, e.g. on a TV screen (or a transparent panel hovering above it, etc.) Have the ability to apply that layout (and its bindings) to another world space object of a different size, e.g. on a smaller or wider TV screen Imagine an office with 15 desks, all with 3 monitors showing the same data feeds and changing statistics, except the monitors were all different shapes and sizes. How could you avoid building all 45 monitor layouts individually, and binding to each field separately? So my question is What is the quot right quot way to build a re usable UI (ideally with UXML USS), display it in world space, and have the ability to update the text in that layout? I thought that UI Builder UXML USS would be the answer, but I am having trouble parsing how my end goal would be accomplished using that (or if that is even an appropriate use case for UI Builder). Fields that are displayed using UIDocuments are not exposed in the Hierarchy, and can't be dragged onto a script's input in the Inspector, for example. I'm able to project a UXML USS layout onto a texture gt material gt object, but I'm not sure how to bind to the fields within the layout The screenshot above is my latest attempt, a POC of a live timer (on the right) manually being updated (using a TextMeshPro field, works great), and the yellow panel to the left is a UXML USS layout pasted onto a texture material that's applied to a panel (in a canvas). On the far left is that same layout being used as a HUD, just to confirm it works the same as the floating panel. In game, this data will not be part of the HUD, it will only be in world space. As a POC, I have been trying unsuccessfully to get the timer value from the gray panel to bind to the quot should be time quot text in the UXML. So, should I just bite the bullet and build each layout by hand using game objects (such as in the gray panel)? Or am I halfway there with the UXML and just misunderstanding how UIDocuments work? Or is there a new smarter way of doing this I haven't heard of yet? Not looking for a full code example or anything, just a push in the right direction. |

0 | Rotate object always at same speed on screen, no matter camera distance? I am rotating a globe like XCOM's hologlobe, I rotate it using Quaternion.RotateTowards(Quaternion from, Quaternion to, float maxDegreesDelta). I found a good value for maxDegreesDelta, in my case it is 5.0f. There is a limit on how close or far the camera can be, let's assume clos is 1.0f and far is 2.0f. I want to be able to zoom into the globe, but obviously when I do, it rotates a bit too fast then. When zoomed out, rotation speed is satisfying When zoomed in, rotation is too fast, making it more difficult to manipulate And the problem is even more evident as game view size gets bigger, i.e. fullscreen. Using Mathf.Lerp and Mathf.InverseLerp, I've tried to make maxDegreesDelta and mouse delta proportional to the distance the camera is but it's hardly convincing. Note I rotate the globe, not the camera. Question How can I ensure object rotates at same speed on screen, no matter how close or far camera is ?

0 | Calculating size and position of Tilemap for camera bounds I'm new to Unity and I'm following a series of tutorials covering off building a 2D Zelda like game. I'm at a stage where I have two Tilemaps side by side and I'm working on a transition between them, triggered when the player collides with a trigger at the edge of Tilemap 1. I have a basic camera movement script which follows the player and constrains the camera within the bounds of Tilemap 1 it's constrained by two Vector2 fields (a min and a max). I got the values for these two Vector2 fields manually in the Scene editor by moving my camera to the desired edges, noting its transform position and entering in those values to the camera movement script. For the transition, I will change these min and max Vector2 values in the camera movement script to then constrain the camera to Tilemap 2. I could just hard code these in again, but it seems like a good learning opportunity to try and calculate these values dynamically. My room change script stores a reference to the camera movement script so that it can amend the min and max values itself. In an attempt to get it to calculate the next room's bounds dynamically, I added a public Tilemap field to the room change script so it can examine it and determine the bounds of the next room itself. I then set this field in the Inspector to point to Tilemap 2. I've so far been unable to calculate these new bounds from the Tilemap reference. The cellBounds property looked promising Position ( 44, 7, 0), Size (19, 20, 1) the size is right, but the actual origin position I calculate manually by moving my camera in the scene editor is 35.14, 2.02. As a result, setting the bounds off of what cellBounds tells me does not work. I've made sure that I've used the 'Compress Tilemap Bounds' too. I've tried accessing individual tiles within the Tilemap and using CellToWorld this only seems to give me the Tile's position relative to the Tilemap (?). The transforms for all of the Tilemaps in my scene and their parents (which are Grids) are set to 0, 0, 0. Basically, I know I should calculate a value of approximately 35.14, 2.02 for my new min position, but I can't see any way to calculate that. How do I go about achieving this, and the same for max? Here is what my scene looks like Main Camera Camera, Audio Listener, Camera Movement (script) Player Sprite Renderer, RigidBody 2D, Box Collider 2D, Player Movement (script), Animator Room1 Grid Ground Tilemap, Tilemap Renderer Collision Tilemap, Tilemap Renderer, Tilemap Collider 2D, RigidBody 2D, Composite Collider 2D Room2 Grid Tilemap Tilemap, Tilemap Renderer RoomTransfer Box Collider 2D, Room Move (script) |
0 | Check whether an object is fully inside overlapped by other objects in Unity3D? I have structures made of voxels (cube gameobjects), and I want to make complex structures from them. But I don't always want to place them on the grid. I want them to be more realistic, like diagonal (Don't mind those visual artifacts) (If I would want to make a fortress like this on the grid, these diagonals would be ugly and zigzaggy.) My problem is that due to this there would be double the voxels at the overlapping places. I want to remove every cube (for example from the selected wall object) which are being FULLY overlapped. This way there won't be double voxels (only partially at the edges, which is fine) and it would look good as well. How could I check this? I don't want to modify the structures manually because both the angle and the other object may vary, thus one structure would need lots of variations. |

Edit A rough sketch of what I am after. Here the black dots represent the physical shape of the object and the lines should be able to wave around the whole object and all be connected, regardless of whether there is an edge there or not. |
0 | Character movement in Unity For an endless runner game such as Subway Surfer, in order to move your character so smoothly in both z axis and x axis, which component of the followings is better CharacterController or RigidBody? Can we use both of them together if so, will it have any effect on the performance of our game? |
0 | How can one achieve the mechanic of hitting cars or bumping into them like in Burnout games' takedown modes? In Burnout games there's this game mode where the player can trash other cars by bumping into them or bumping them into walls. As you can see in this video link This is known as a takedown. I'm working on a racing game and I would like to work on a similar feature. I added a bouncy material to my cars collider in hopes that this effect would be replicated to some degree but all it did was to slightly push the cars away from the player. I don't have that much experience in making games so I'd appreciate any help I could get about the subject. |
