0 | Problem with Blender model imported to Unity (Lighting problems) I made a simple box in blender and imported it to unity. Now I'm facing with this weird lighting problem I've been messing around with normals, duplicated vertex, lots of things, even lightning properties but still I'm not getting any results at all. Why does this happen and how can I solve it? Source blend file https drive.google.com open?id 1Ze1JBRFBvhnnY w36U2KDe7Q2zcfXsmf |
0 | Prototype experience Unity3D vs UDK Has anyone yet prototyped a game in both Unity3D and UDK? If so, which features made prototyping the game easier or more difficult in each toolkit? Was one prototype demonstrably better than the other (given the same starting assets)? I'm looking for specific answers with regard to using the toolkit features, not a comparison of available features. E.g. Destructable terrain is easier in toolkit X for reasons Y and Z. I can code, so the limitations of the inbuilt scripting languages are not a problem. |
0 | Conservation of energy of a bouncy ball in Unity3d My problem is that in the project I have a ball with a physicMaterial where Dynamic Friction and Static Friction both are 0 Bounciness 1 Friction Combine is set to Multiply Bounce Combine is set to Maximum This ball has a rigid body attached in which mass 1 drag and angular drag both are 0 useGravity true There are some cubes which create a boundary for the ball to bounce inside. The ball bounces in a closed boundary. The problem is overtime its top velocity keeps on increasing and after sometime it gets out of the boundary. I want the velocity of this ball to NOT exceed a provided maxVelocity. Here i am sharing my project through google drive bounceProblem.unitypackage |
0 | Unity3D behaves differently in scene and game view We are having AI being able to shoot. Everything works fine when having them play in Scene view, but when going into Game view the position they are shooting from is different. Does anyone know what could cause this? That the Unity "Scene view" behaves other than "Game view"? Hope there's anyone there to help us out, thanks in advance. |
0 | Preventing a Child object (eg. some weapon) from going inside other objects in the scene? I have Cube with a sword like object as its child object. But when the cube moves in the scene the sword goes into the other objects in the scene. The sword have a BoxCollider attached to it but the scene contains objects that are stationary and don't have a Rigidbody attached as I don't want them to be controlled by physics, same for the sword. If I attach Rigidbody to it then it will be displaced from its main position on collision. I tried to render only the Cube including the sword with one camera having higher depth value then the main camera in the scene. If my game was in first person then this works fine but In 3rd person when object get behind other objects in the scene we can still see the object. How can I prevent the sword from going into other object without being controlled by physics? Image |
0 | How to disable gravity for a RigidBody moving on a slope? I created a script that handles movement for my player (moving around, going down and up slopes). However, since I'm using a RigidBody not a CharacterController when I go up slope and stop on the middle of it the gravity pulls me backward, which is fine, but the problem is when I move forward, the gravity force pulls me backward when I'm trying to go forward. This problem wouldn't have appeared if my character wasn't a sphere but my character is a sphere so it always roll down when gravity is applied to it. What I want is to somehow stop the gravity for a second or reset it to zero when I move my character, and when I'm going up a slope so it won't hold me back. I tried if(grounded) rb.velocity Vector3.zero but I don't think it's the right approach. |
0 | How to stop counting point when player dies (Destroy) In my game, I'd like to stop counting points when the player's y is 4. When the pink and red balls fall off the Plane the player gets points. But it seems a bit strange to be able to collect points after the player dies. This is the code for the player if (transform.position.y lt 4) Destroy(gameObject) gameManager.GameOver() And in the GameManager.cs I have this public bool isGameActive public void UpdateScore(int scoreToAdd) score scoreToAdd scoreText.text "POENG " score public void GameOver() isGameActive false restartButton.gameObject.SetActive(true) gameOverText.gameObject.SetActive(true) And this is the code for adding points when the enemies fall over the edge if (transform.position.y lt 4) Destroy(gameObject) gameManager.UpdateScore(pointValue) How can I make the game stop counting points when the player dies? |
0 | Unity3d Rigidbodies overlap even at low speeds I have an issue that I can't solve. There are many questions relating to similar issues and they come down to "change some settings" and "object is travelling too fast". My problem doesn't seem to equate to either of these. I am running through the basic tutorial for the Breakout Game and have added some of my own tweaks to the code, my issue is that even at low speed my ball overlaps with the bricks, rather than bouncing off them. I have read various related questions but nothing seems to fix this for me. Things I've done Set Project Settings Physics2d Maximum penetration For Overlap 0.0001 Set Ball RigidBody Collision detection to "Continuous Dynamic" . Set Brick RigidBody Collision Detection to "Continuous" Forced a speed limit on the ball of 25 15. Which I think is not fast at all, as most the given solutions are talking about situations arising when the offending object is travelling at much higher speeds. Bricks are standard rigidbody cubes and ball is a standard rigidbody sphere. According to this answer I have also set the rigidbody interpolation to "interpolation" for both ball and bricks. But this seems processor expensive and doesn't solve the issue. As well as set the Project Settings Physics Solver Iteration Count to 25. This does seem to have helped somewhat (ball no longer gets "stuck" inside brick wireframes, but still overlaps). Below are some screenshots of my issue and my code. The only aspect that I can't fully account for is that I've added an acceleration function so when ball is launched it accelerates over a course of several seconds to it's max speed. It's start speed is 8 (although the force applied is actually 1000 when launched, ignore that figure), and the max speed is set to 25 15. I don't know enough to say if this is somehow "breaking" rigidbody overlap detection but it seems pretty silly if so. See line 63 below Ball Source Code using UnityEngine using System.Collections public class Ball MonoBehaviour public float initialVelocity 500f public float accelerationSpeed 5f public float MaximumSpeed 15f private Rigidbody rb private bool ballInPlay false void Awake () rb gameObject.GetComponent lt Rigidbody gt () void Update () if (Input.GetButtonDown("Fire1") amp amp ballInPlay false) transform.parent null rb.isKinematic false rb.AddForce(new Vector3(initialVelocity,initialVelocity,0)) ballInPlay true void FixedUpdate () Gradually increase ball speed if (ballInPlay true amp amp rb.velocity.magnitude lt MaximumSpeed) speedUp() Debug.Log("Ball Speed is " rb.velocity.magnitude) Clamp to maximum speed if (ballInPlay true amp amp rb.velocity.magnitude gt MaximumSpeed) rb.velocity rb.velocity.normalized MaximumSpeed rb.velocity.magnitude void speedUp() This is line 63 rb.AddForce(rb.velocity.normalized accelerationSpeed,ForceMode.Acceleration) Why are the rigidbodies not detecting and preventing overlap? |

0 | What makes a shader function with a LineRenderer? A LineRenderer has both Material and Color properties. But many shaders do not work, ie the line will not respect the Color property, or the line will show black (regardless of the materials having its own color). For example the Standard, Diffuse, Mobile Diffuse shaders all show black. Unlit Color ignores the LineRenderer color and uses only the Material Color property. Particles Additive works great, but Particles Standard Surface does not. What part of the shader code is important to make a LineRenderer display using its own Color property? When it does work, how should shader code decide how to merge between the two colors? |
0 | Looking for the best way to store game data that is meant to be user editable at runtime I have a broad question, hopefully I'll synthesize it well. I've been looking for the best way to store the standard data of my project. So far, I've found 4 possible answers to my problem Binary files, Json files, XML files and local DB(using SQLite). While the first 2 seems to be common sense for store data, I would still need some opinions about it, instead of create a bunch of content and code in vain. The chosen option must generate files that can be editable at runtime. Already used some XML files for basic saving and watched tutorials on Json and Binary files but I'm still uncertain about what road to take. I believe DB's are a different animal, but maybe it would worth for my case. To contextualize, my project is a sports game, so I must start to generate and store virtual players and teams. After that I need to link those virtual players at their respective teams. It happens that I would like to enable human players to edit those generated virtual players and teams attributes at runtime through some kind of editor. Furthermore, I want to enable human players to create their own virtual players and teams, so the chosen method must have scalability, so it's expected to have hundreds of teams and thousands of virtual players at some point. My target platform is PC, so file sizes and general performance isn't so critical as it could be on mobile for example. Anyway, hopefully my doubts are clear enough. It would be cool if someone have something to say, I would like to know the best choice for my case. PS Already take a look at these 2 questions How to choose how to store data? Would it be better to use XML JSON Text or a database to store game content? But most of it's answers have some years now and I still have doubts on this matter. |
0 | I have a game based on combining 2 ingredients to create a product. What is the best way to code this? (Unity) So to go a bit more in depth, in my game, you can combine a variety of ingredients to make a product. For example, you could combine water and dirt to make mud. What I am currently doing to achieve this is by listing each combination possibility that a particular ingredient has. The one thing i managed to do to make it a little more efficient is that I managed to remove duplicates (So for example, if i have coded ingredientA IngredientB Cheese, there isn't another entry for IngredientB Ingredient A Cheese). The problem I have with my method is that it is very annoying adding new ingredients. If i do so, I have to go back to every previous ingredient i have coded, and add it's interaction with the ingredient(s) i want to add. The amount of ingredients I have means this is becoming increasingly time consuming. Is there a better way to do this? This is a Unity game, coded in C . Let me know if you need any further info. |
0 | How to build a hidden 3D snapping grid effect? Looking to build a 3D grid similar to the image below taken from Google Blocks. Seems like it consists of these main components A set of spheres that can go transparent. A stencil that follows the controller's location. When stencil overlaps with spheres, they show up, otherwise, alpha fades to zero. Any advise on how to approach building this? |
0 | How to flatten the collider for a tilemap? I am relatively new to game development, and am working on a simple 2D platformer. I have created a tilemap and painted some tiles for the character to walk on.. but he is getting stuck. Yes, I know this is a common question and I did find some answers (including this one Player gets stuck on edges between TilemapCollider2D tiles), but none seem relevant for me. The thing is my tiles are not flat.. they have pointy edges due to grass.. see the image below As you can see, the edge is not flat. I have overcome the problem of getting stuck by changing the quot Edge Radius quot to what you see in the above screenshot and that works, but the character now looks like he is floating slightly above the ground. Is there any way I can just tell Unity to ignore the jagged grass and make the collider flat and move the edge of it down a bit? That way it would fix the issue and also have the added bonus of looking like some of the grass is behind him and some in front.. |

0 | Changing contents of level depending on which character was selected I'm trying to create a character selection menu in Unity, where each character has their own version of the level that follows. There are about 10 characters. Each character has a different location where they spawn in the level, and each enemy has a different spawn position as well, depending on which character was selected. What I have been doing is to create separate levels (scene files) for each character. Then in the character selection menu, I load the level depending on the level selected by the user. This seems to be a lot of code and data repetition, as the scene is the same in all levels it's just that the spawn positions and enemies are different. Is there any way have only one level scene, and get the spawn position and enemy spawns based on the character? This is the code I have so far in GameManager.cs public GameObject enemy public Transform enemySpawnPoint public GameObject player public Transform playerSpawnPoint public static GameManager instance private void Awake() if (instance null) instance this void Start() StartCoroutine("SpawnEnemies") SpawnPlayer() IEnumerator SpawnEnemies() while (true) yield return new WaitForSeconds(1.0f) SpawnEnemy() public void SpawnEnemy() Vector3 enemySpawnPos enemySpawnPoint.position Instantiate(enemy, enemySpawnPos, Quaternion.identity) public void SpawnPlayer() Vector3 playerSpawnPos playerSpawnPoint.position Instantiate(player, playerSpawnPos, Quaternion.identity) ...and the character selection script public void Level1() SceneManager.LoadScene(1) public void Level2() SceneManager.LoadScene(2) ... public void Level10() SceneManager.LoadScene(10) Now the issue is, if I want to make any changes in one scene, like the skybox or background color, I will have to open all the other level scenes and make the changes. Another thing is that if I want to add new levels, I will have to do the same thing, which seems like a lot of repetition. Is there some way to set the enemy prefab, enemy spawn positions, player prefab and player spawn position once the character has been selected? For example, if the user clicks on level1, all the preceding variables are set automatically and so on..... |
0 | ScreenToWorldPoint problems in otherwise awesome Unity demo I am using this neat Unity demo I found on Stack Overflow, which demonstrates texture masking via RenderTexture Can you erase a texture in real time in Unity But the mapping from mouse position to world space is wrong.

Through debugging I found that the world coordinates returned on line 49 are off. I also tried setting the z value of mousePosition to 10, even though the cameras are orthographic, like so Vector3 mousePos Input.mousePosition mousePos.z 10 Vector2 v GetComponent lt Camera gt ().ScreenToWorldPoint(mousePos) The mapping from the mouse to worldspace is still wrong though. Mouse coordinates within a small rectangle near the center are mapping to the full width and height of the image in world space. |
0 | Get closest Child to cursor I'm currently rewoking my RTS cover system. This should highlight the closest coverspots from my mouse cursor and sent the units to these locations. everything works, but I can't get the closest sport, it always selects the sames ones, regardless to the mouse position. These cover spots are child objects of the obstacle, that has this script attached. This is my not working implementation of the idea void Update() var dist Mathf.Abs(transform.position.z Camera.main.transform.position.z) var v3Pos new Vector3(Input.mousePosition.x, Input.mousePosition.y, dist) v3Pos Camera.main.ScreenToWorldPoint(v3Pos) mousePos v3Pos ... public void getPointDistances() foreach (CoverPosition pos in coverPositions) if (!pos.occupied) pos.distanceToCursor Vector3.Distance(pos.transform.position, mousePos) Array.Sort(coverPositions, delegate (CoverPosition x, CoverPosition y) return y.distanceToCursor.CompareTo(x.distanceToCursor) ) Later, I simply Iterate over the sorted array and make it visisible. I'm woking on this for hours, but i cannot find, a solution why it always displays the same cover spots. I hope, someone can find my (possibly stupid) error.

0 | Keeping a Character Controller grounded? I've got a character that makes use of isGrounded() to determine whether I can jump, whether my air jump is reset, and the amount of friction to be applied. I've run into a common problem, isGrounded() is fluctuating every frame returning true and false randomly resulting in jagged movement. The standard suggestion is to constantly apply gravity. Unfortunately, aside from any other more nuanced issues that this could result in, this only works for me if I apply so much gravity that I am no longer able to climb up slopes. I need a way to keep the character grounded without applying large amounts of gravity every frame. |
0 | Rotating game object without using localEulerAngles I'm building a player controller. While aiming, the player can rotate the chest bone. This looks as if the character aims in different directions. The chest bone should only be allowed to rotate within a certain range. If this range is exceeded (either to the left or to the right), the chest bone should stay at its current rotation, and the player should be rotated instead. I'm having problems applying the desired rotation to the parent game object instead. I'm trying to work with the localEulerAngles in order to applying an additional Y rotation to the gameobject, but the Y rotation value tells me for example "359.9" while I expected to work with a value of 0. private void pHandle LateUpdate Aim() Quaternion oldNeckRotation Neck.transform.rotation Fade old input before capturing new, so we don't dull the freshest data. float yawBlend Mathf.Pow(1.0f Aim yawInputFalloff, referenceFramerate Time.deltaTime) A Lerp toward zero is just the same as a multiplication by the blend factor.

0 | Cannot implicitly convert type 'T' to 'UnityEngine.Vector3' I'm trying to use C generics on a method in order to send a Vector3 (position) as a parameter. I can print the value correctly but can't store it on a local variable. I also can't access its x, y or z attributes separately. I'm implementing a state machine. My intention is to use generics for allowing sending different parameters to the different states.

So for example the player will be on the DefaultState something happens change state to HeroTeleportingState while sending it it's new position This is my Enter method on the HeroTeleportingState class void IState.Enter lt T gt (T newPosition) The following line prints the correct value Debug.Log("move this hero to " newPosition) The following lines don't work pos newPosition pos.x newPosition.x The method call is just something like currentlyRunningState.Enter(Vector3.one) pos newPosition gives me the following error on Visual studio (I'm paraphrasing cause my visual studio is in spanish) Cannot implicitly convert type 'T' to 'UnityEngine.Vector3' And pos.x newPosition.x gives me something like 'T' does not contain a definition for 'x' and no extension method 'x' accepting a first argument of type 'T' could be found EDIT IState interface public interface IState void Enter lt T gt (T value) void Execute() void Exit() |
0 | Instantiate and launch prefab that's overlapping player? I m very new to Unity and C . I m trying to create my first game and I have now invested about 15 hours trying to find solutions to this issue...I m stumped! My player sprite (blue square) needs to launch a prefab sprite (red circle) of similar size appearing to originate from itself.

0 | How to align angular velocity wit target rotation in 3D? I'm making a space crew sim (controlling a ship) and have recently posted a question about how to calculate ETA between two rotations. I how now a new question more well defined. Background I have Qtarget and Qcurrent(the ships rotation) and can find Qdelta using Qdelta Qcurrent 1 Qtarget. And I have the angular velocity in rotation speed around the world axis from the Unity. I want to control the ship only using delta angular velocity around ships axis. I want to get the angular velocity aligned with Qdelta so i can just use that angular velocities e.g. x part and the angel to solve for if I should accelerate or decelerate and just decelerate along the y and z axis. After that I want to rotate that data back to ship rotation. I have this test code using UnityEngine using System.Collections public class RoationTest MonoBehaviour public Vector3 startAngularVelocity new Vector3() public Vector3 targetRoation new Vector3() public Vector3 maxShipDeltaAngularVelocity new Vector3() Use this for initialization void Start () rigidbody.angularVelocity startAngularVelocity Mathf.Deg2Rad rigidbody.WakeUp() Update is called once per frame void Update () Vector3 currentAngularVelocity rigidbody.angularVelocity Mathf.Rad2Deg This seams to work Quaternion deltaRoationQuat Quaternion.Inverse(rigidbody.rotation) Quaternion.Euler(targetRoation) This seams to work float deltaAngel Quaternion.Angle(rigidbody.rotation,Quaternion.Euler(targetRoation)) This seams to work Vector3 xAxis new Vector3(1,0,0) Vector3 deltaRotationAxis deltaRoationQuat.eulerAngles Vector3 deltaRotationAxisClampedToShortestDist ClampEulerAngelsToClosest(deltaRotationAxis) Quaternion AlignQuat Quaternion.FromToRotation(deltaRotationAxisClampedToShortestDist, xAxis) Vector3 angularVelocityAligend AlignQuat currentAngularVelocity This should be Quaternion.Inverse(AlignQuat) currentAngularVelocity But that does not work as I think I should but this do. Vector3 maxDeltaAngularVelocityGlobalRotaion rigidbody.rotation maxShipDeltaAngularVelocity Transform max delta angular velocity from ship rotation to global space. The same as maxShipDeltaAngularVelocity Quaternion.Inverse(rigidbody.rotation) but Unity do not suport that. Vector3 maxAlignedDeltaAngularVelocity AlignQuat maxShipDeltaAngularVelocity private Vector3 ClampEulerAngelsToClosest(Vector3 rotation) if(rotation.x gt 180) rotation.x rotation.x 360 if(rotation.y gt 180) rotation.y rotation.y 360 if(rotation.z gt 180) rotation.z rotation.z 360 return rotation Questions Why do this Vector3 angularVelocityAligend AlignQuat currentAngularVelocity align y axis with x axis? It should be Vector3 angularVelocityAligend Quaternion.Inverse(AlignQuat) currentAngularVelocity in my understanding. Also how can Vector3 maxDeltaAngularVelocityGlobalRotaion rigidbody.rotation maxShipDeltaAngularVelocity be right? General thoughts Is this clear enough or am I taking the wrong approach? I general words I want to find the optimal solution in every frame on how to reach target rotation only using delta angular velocity limited by a max value (the ships engines effect) and also receive and ETA. I understand this is an approximation I state above since i assumes no rotation perpendicular to Qdelta but this solution will do for a start. |

0 | How to move player out of multiple penetrating colliders? The player in my game can teleport like Noctis from ffxv.The player shots a weapon projectile and then teleports to the projectile. I'm using raycast to calculate the weapon position after thrown. However, I need to check if the weapon is stuck in an unteleportable position after being thrown. It is possible to have multiple penetrating colliders. Ex spear gets sandwiched between two walls that is narrow enough for the weapon to pass through but not tall enough for the player to stand. I want to somehow check for a nearby valid position for after teleporting in that situation. I also want the teleport to fail if the weapon is horizontally in the middle of the "pipe". I could do a bunch of overlapBox checks within a radius distance from the teleport point but that doesn't seem efficient. I want to give the player some leeway when aiming a teleport. Also, the teleport is not immediate. The player can wait some time before teleporting to the weapon. So it is possible for a moving platform to block a raycast from the player. In which case I still want the raycast to succeed. I'm using unity and a custom raycast based 2d character controller for normal movement. |
0 | Position GUI Text in 2D game I am working on a 2D game, and my camera is a orthographic with a size of 320. I want to display some text, but not with OnGUI(). Rather, with a GUI Text game object. I couldn't help but notice that positioning my GUI Text object is a real pain apparently, the onscreen coordinates where the text appears range from 0 to 1. That is, 0.5 is the center of the screen. If I wanted to put my label at exactly (100,50) regardless of the screen size, I would have to calculate something like (100f Screen.width, 50f Screen.height) Is there a way to tell the GUI Text to appear at the actual transform position as it appears on the scene editor? Currently, if you move the GUI Text game object's transform slightly to the right, the rendered text will be displaced a LOT to the right instead... |

0 | How to store a Transform , grid in an ArrayList? I am new to Unity game dev and trying to expand my knowledge of data structs. I'm building a match 3 game, and I currently have a multi dimensional ArrayList holding transform coordinates on a grid of x width and y height. I have game objects tied to these coordinates in world space, with the grid syncing the data back in game space. I am attempting to push these coordinates into the nested list (familyList) to be deleted pending 3 or more units being added to familyArrayList (seen below). Here's the abridged code private static Transform , grid new Transform width, height public static ArrayList familyArrayList new ArrayList() Go through game grid line by line and add game objects from game space into family ArrayList for (int y height 1 y gt 0 y ) for (int x 0 x lt width x ) if (grid x, y ! null) Add grid x, y to familyArrayList familyArrayList.Add(grid x, y ) Debug.Log(familyArrayList 0 ) Output Green Unit(Clone) (UnityEngine.Transform) How can I get familyArrayList to properly story the grid coordinates and not the game object the grid coordinates are referencing? i.e. familyArrayList 0 '3,4' Should I instead use a nested list? At a later point in the code, I want to clear the game object from the board in world space as well as set the grid x,y to null Loop through all family array and destroy game objects foreach (var x in familyArrayList) Destroy(familyArrayList(x).gameObject) Loop through all family array and set their values to null in grid as well foreach (var x in familyArrayList) familyArrayList(x) null But I get errors like "Argument 1 cannot convert from 'object' to 'int'" and "Non invocable member 'Piece.familyArrayList' cannot be used like a method" which I can imagine are explained by my above problem of not storing the grid coordinates properly and instead storing the referenced game object. I'm truly stumped on this problem and thank anybody in advance who can point me in the right direction to solving this. |
0 | When creating an FPS style game, how should the iron sights be setup? I am working on creating an FPS style game for learning purposes. I previously was using self created animations for aiming down the iron sights of a gun. The animation would play when you zoom to iron sights and it would hold it there as long as you have the mouse held down. However, talking to a high rated designer, he told me usually it is done with a second camera that sits perfectly aligned with the guns iron sights. I would imagine you would still have to have an animation that then transitions you into that iron sight camera though. Now my animation works fine but I feel I may run into a problem later down the road if I am approaching it the wrong way from the start. Can someone verify the right way to do this and explain why it is? |

0 | Why does physics not behave consistently in Unity? I'm making a game in which AI players throw a ball. In the screenshot, you can see the arena which is separated by a net in the middle. Each side of the arena has 6 players belonging to one of 2 teams. Right now, one of the players on the right side has the ball (the top right player). He is going to throw the ball to the left side. According to my code, the ball should always land on the same place, because the player always applies the same force to the ball. However, I have noticed that the ball doesn't always land in the same place. I have marked where I've seen the ball land with several red circles. Interestingly, on my main PC, the ball almost always lands on the right most circle. It rarely lands on the other circles, although that does happen. On 3 other PCs I've tested this game on, however, the ball most often lands on the legs of the top left player, sometimes on his head or behind him, but never on the right most circle (in front of him). My game relies heavily on physics. The AI is supposed to calculate how to throw the ball to get it to land on a very specific location, as well as guess where it'll land depending on the ball's position and movements. If the physics don't behave consistently on all machines all the time, how is the AI supposed to calculate all of this accurately? Here is the code in charge of throwing private IEnumerator Serve() var ball GameObject.Find("Ball").GetComponent lt BallController gt () if (ball.ServingPlayer ! this) yield break yield return new WaitForSeconds(3) Vector3 shootDirection transform.forward.normalized var q Quaternion.AngleAxis( 45, transform.right) ball.RigidBody.AddForce(q shootDirection 20f, ForceMode.VelocityChange) As you can see, the ball is always thrown "forward" (facing the net) at a 45 upward angle, using a normalized vector and a constant speed (20f). Before each throw, the position of the players is reset to the exact same location (and rotation) they are seen on the screenshot. player.transform.localEulerAngles new Vector3(0, playerRotation, 0) player.transform.position startingposition posOffset In this case, playerRotation is either 90f or 90f depending on which side the player is on, startingposition is their "horizontal" position (relative to the net), and posOffset is their "vertical" position. The ball has its velocity and angular velocity reset, but not its rotation (since it's a sphere, its rotation shouldn't influence anything). Its position is also set to a fixed location relative to whichever player has to serve the ball. rb.velocity Vector3.zero rb.angularVelocity Vector3.zero transform.position ServingPlayer.ServingPosition Here, rb is the ball's RigidBody. Finally, I am not influencing the ball's movement in any way. I simply apply a force to it when serving, which happens only once. 3 seconds after the ball lands, the match is reset and everything repeats. The flow is basically like this (pseudocode) Start() ResetCourt() StartCoroutine(Players 0 .Serve()) event BallLanded() wait for 3 seconds repeat starting with ResetCourt() I really need the ball's trajectory to be reproducible every single time on every possible machine. Obviously I'm doing something wrong here, but what? |

0 | How can I create color fonts to be used in Unity? I've been searching, downloaded a couple programs that lets you convert images into fonts, but none let you obtain the color. They all switch them to black and white. While searching the internet, I found a few colored fonts. Yet, almost all games have their own fonts that are colorful. How do they do it? Did they just opt to program the font with coded position and sizes? I'd just like to make my own true type or open type font (ttf or otf) from some images I created. And the images aren't even that colorful, just fill and stroke color. |
0 | Unity Animate Sprite Shape Sprite? Is it possible to animate a sprite shape? I don't see the Sprite Shape Profile in the animator properties, so I was just wondering if there's another way to do that. To clarify Our game is 2D animated by hand, and one level has conveyor belts that span the level. We can animate it normally, but that will end up taking more video memory than if we were able to animate the conveyors as tiled sprite shapes. It may not end up being worth the effort to save the memory, but I figured it was worth a shot. Because the sprites span the level, they end up taking up lots of space in a sprite atlas. |

0 | Unity Rigidbody sitting on top of another Rigidbody does not move with the Rigidbody its sitting on I have a mesh with a rigid body that moves back and forth like a platform. Other rigidbodies fall onto the upper surface of this cube. The problem I have is that when the platform rigid body moves the other rigid bodies stay in the position they landed in, they do not move with the cube. Everything else physics wise works. I have tried adding a physicsmaterial to both the platform and the rigidbodies falling onto the platform but this made no difference. I do no want to tether them to each other because I want them to fall off when they are pushed by other objects. The platform is moved back and forth using the RigidBody.MovePosition function. |
0 | Multiple Input.GetKeyDown happens in low frame rate There is a code that needs to be invoke each time user pressed specific button in my game. So I used Input.GetKeyDown to achieve that, but some reason, that code invokes multiple times even I keep pressing the button. After some tests, I figured out this happens a lot when the game has low frame late. In a very laggy moment, GetKeyDown returns true very many times. void Update() if(Input.GetKeyDown(KeyCode.RightArrow)) print("Pressed") I saw a similar issue in here but couldn't find any related information. https forum.unity.com threads problems with input at low framerates.16828 My game is a very input sensitive game, so my code when the user each time pressed a specific button always invoke when they pressed. I checked my keyboard is something wrong, but there was no problem with my keyboard. Why does this happen? According to the Unity doc, it said Returns true during the frame the user starts pressing down the key identified by name If I used wrong way, then how do I check each time user pressed a button?

0 | How should I load change activate scenes? Scenes are confusing the hell out of me and I'm pretty sure they should be simple to understand. When the game loads, only the current scene has a buildIndex ! 1. In order give it a 'real' build index I need to load it by path or name (because there's no build index). The scenes are ten game scenes, one title scene and one persistent scene (which has the player and the status bar with the score etc.). Should I load a scene every time I change scene and then load additive afterwards or should I be using Set Active Scene? All the scenes are ticked in the Build Settings. I'm looking at the index with this private void Start() var sceneName "Persistent" var sceneBeforeLoading SceneManager.GetSceneByName(sceneName) Debug.Log( "Scene sceneBeforeLoading.name , BI sceneBeforeLoading.buildIndex ") SceneManager.LoadScene(sceneName) var sceneAfterLoading SceneManager.GetSceneByName(sceneName) Debug.Log( "Scene sceneAfterLoading.name , BI sceneBeforeLoading.buildIndex ") Which outputs Scene , BI 1 UnityEngine.Debug Log(Object) Title Start() (at Assets Scripts Title.cs 10) Scene Persistent, BI 1 UnityEngine.Debug Log(Object) Title Start() (at Assets Scripts Title.cs 13) |
0 | Does marking a GameObject as static actually improve performance? I'm currently working on a small game that will include somewhat large levels. Each level will have a somewhat large amount of GameObjects lying around as props. I was told by a friend of mine that marking the GameObjects that the map is comprised of as static will improve performance. However, I am aware that this can greatly increase the amount of space the built game takes up on the disk. Does the performance boost gained from marking GameObjects as static outweigh the cost of increased build size? Is there even a performance increase at all? |

I'm trying to create a nice looking hand of cards, when the card is hovered over, it bobs up and down and rotates. This is triggered by OnPointerEnter, however, whenever it turns on its side and out of the mouses path OnPointerExit triggers, I've tried MANY things, including a bool that triggers the hover effect OnPointerEnter but it is just toggled off when it's turned on its side.

0 | How to calculate the stopping distance of a wheel collider? I have an 'AI' bus in my game that needs to pull over occasionally at a bus stop. What I want to do is change the acceleration and brake force based on the stopping distance of the bus. I don't want to simply use the distance between the bus stop and the bus because each time the bus pulls over, it could be traveling at a different speed. Right now it uses the distance between the bus stop and the bus. It doesn't really work well though because if a bus is traveling faster, it will take a longer distance to stop and will likely go past the bus stop. Same thing if it were going slower. How do I calculate the stopping distance my bus will take to come to a complete stop? |

0 | I found out how to rotate both Sphere and Cube (1) like a Turret facing a target but why is it so hard? I just added 3 objects to my scene to a new project. To be sure where the problem is I created a new project. Then added to the scene 2 Cubes and 1 Sphere 1 empty GameObject. Cube is the target. Sphere and Cube (1) are the Turret and both are childs of the empty GameObject. The script is attached to the empty GameObject. The logic say if I will rotate the empty GameObject both Sphere and Cube (1) will rotate at the same time. But I found that if I'm not setting both Sphere and Cube (1) same direction before running the game they will never face to the target only the Sphere. I had to figure out where is the Sphere facing direction before running the game and change the Cube (1) to face the same direction of the Sphere on the Z Blue axis. I can't figure out yet and understand why is it so hard to rotate two objects at the same time to be facing the same direction (target). Now it's working once the sphere and the cube (1) are facing same direction before running the game. It didn't work if I made them childs or parents or changed the Cube (1) position to 0,0,0 nothing. They were both rotating but never faced the target only the Sphere faced the target. So now each time I want to rotate two objects at the same time to face another gameobject like a turret, or cannon or anything that is built of two parts I need first to make them facing same direction ? I guess I did something wrong but not sure what. The script using System.Collections using System.Collections.Generic using UnityEngine public class Rotateturret MonoBehaviour public float speed 3.0f public GameObject m target null Vector3 m lastKnownPosition Vector3.zero Quaternion m lookAtRotation private void Start() Update is called once per frame void Update() if (m target) if (m lastKnownPosition ! m target.transform.position) m lastKnownPosition m target.transform.position m lookAtRotation Quaternion.LookRotation(m lastKnownPosition transform.position) if (transform.rotation ! m lookAtRotation) transform.rotation Quaternion.RotateTowards(transform.rotation, m lookAtRotation, speed Time.deltaTime) bool SetTarget(GameObject target) if (!target) return false m target target return true Here is a link for a short video clip I recorded showing what I mean Video clip of the problem |

0 | Keep state in Unity editor without hitting serialization In my game I have a MonoBehaviour WorldView that, when created at editor time, initializes a large dictionary. Later from a Editor WorldViewEditor I call WorldView.SetBlock() that tries to access this dictionary, but finds it empty. If I understand correctly this is because my editor doesn't access the same WorldView instance, but rather a copy it received through serializing and de serializing my original instance. Pushing this dictionary through the serializing process is a performance nightmare and not supported by Unity out of the box. This dictionary should never be shown in any editor, is private to the instance and initialization will be called every time the scene is loaded. This sounds like a perfect case for keeping it somewhere outside the serialization process. I could try to leverage ISerializationCallbackReceiver but this still requires me to pull the entire dictionary through some serialization process. I'm looking into keeping everything state related in a separate library outside of unity, but this has it own downsides. Is there a way to put this dictionary in a place where its state is kept? |

0 | Programmatically creating sprite animations in Unity Some background I have a set of animated gifs which I've converted to spritesheets, which are then imported into Unity as multiple sprites. The end result is that each spritesheet in the Unity editor contains a list of sprites named xxxxxxx yyy zzz for example 1313000 000 000 to 1313000 000 014, followed by 1313000 001 000 to 1313000 001 008, followed by 1313001 000 000 to 1313001 000 031, and so on. Now, I would like to make simple sprite animations out of this spritesheet. In the example above, 1313000.anim should contain all sprites beginning with 1313000 played in numerical order, 1313001.anim should contain all sprites beginning with 1313001, etc. etc. This isn't hard to do by hand highlight desired range of sprites, drag and drop but we're talking about a lot of animations. Creating an editor script which lets me right click a spritesheet and generate a series of .anim files seemed the best solution, but I'm turning up conflicting info on the subject. Getting a sprite array from the spritesheet is simple enough, but programmatically creating an animation is something very few people seem to have discussed. Essentially, is it possible and practical to create and populate sprite animations from an editor script? |

Code TouchControll.cs public GameObject PlayersPartical void OnTriggerEnter2D(Collider2D other) here my player collided with obstacle foreach (Transform child in transform) if (child.tag "point") GameObject partical Instantiate(twopartical Random.Range(0,1) , transform.position, transform.rotation) ParticleSystem heal partical.GetComponent lt ParticleSystem gt () heal.Play() GameObject partical Instantiate(PlayersPartical, transform.position, transform.rotation) ParticleSystem heal partical.GetComponent lt ParticleSystem gt () heal.Play() ObjectPooler.Instance.SpawnFromPool("redandbluepartical", transform.position, Quaternion.identity) ObjectPooler.cs public static ObjectPooler Instance public void Awake() Instance this System.Serializable public class Pool public string tag public GameObject prefab1 public GameObject prefab2 public int size public List lt Pool gt pools public Dictionary lt string, Queue lt GameObject gt gt pooldictionary which gameobject you should be pool void Start () pooldictionary new Dictionary lt string, Queue lt GameObject gt gt () foreach(Pool pool in pools) add a pool in list Queue lt GameObject gt objectpool new Queue lt GameObject gt () for(int i 0 i lt pool.size i ) GameObject obj Instantiate(pool.prefab1) GameObject obj1 Instantiate(pool.prefab2) obj.SetActive(false) obj1.SetActive(false) objectpool.Enqueue(obj) pooldictionary.Add(pool.tag, objectpool) public GameObject SpawnFromPool(string tag,Vector3 position,Quaternion rotation) two tag red and blue partical if(!pooldictionary.ContainsKey(tag)) Debug.Log("doesnot exist" tag) return null GameObject objecttospawn pooldictionary tag .Dequeue() here how to call my trigger objecttospawn.SetActive(true) objecttospawn.transform.position position pos objecttospawn.transform.rotation rotation rotation pooldictionary tag .Enqueue(objecttospawn) return objecttospawn Image1 Image2 How do I call these particles? |
0 | I can add event animation but I can't add keyframe? I am trying to add animation to my UI panel but the problem is I can't add a keyframe to my animation (the button is grayed out). But I can add event animation (the button is not grayed out). Here is the video of what's happening. Anyone know how I can resolve my problem? |
0 | Is there anyway to disable the script "gameplay" from running once you start the simulation? Was following the tutorial in this video https oxmond.com how to make multiple copies of a gameobject on how to duplicate object. I want to modify my code I learned from this tutorial https www.youtube.com watch?v OR0e 1UBEOU amp t 4178s so that the bird will increase its size proportion to the distance travel and when scale gt certain value, it break into 2 identical bird object that possess the same properties as the first one. I already did the part size increase in proportion to the distance travel. Now I create an empty game object and attach the script quot explode quot together with prefab of the bird object to it but how to write the proper code to carry out the function if the main bird object is destroyed then it run the code quot explode quot to duplicate bird? using UnityEngine using UnityEngine.Assertions.Must using UnityEngine.SceneManagement public class Bird MonoBehaviour Vector3 OldPosition Vector3 DistanceDifference float TotalDistance 0 Vector3 initialPosition private bool birdWasLaunched SerializeField private float launchPower 500 void start() OldPosition transform.position private void Awake() initialPosition transform.position void Update() if ( birdWasLaunched amp amp GetComponent lt Rigidbody2D gt ().velocity.magnitude gt 0.1) DistanceDifference transform.position OldPosition TotalDistance DistanceDifference.magnitude OldPosition transform.position transform.localScale new Vector3(0.2f Mathf.Abs((TotalDistance 0.2f)), 0.2f Mathf.Abs(TotalDistance 0.2f) , TotalDistance 0.5f) if (transform.position.y gt 20.00 transform.position.y lt 20.00 transform.position.x gt 23 transform.position.x lt 23) string currentSceneName SceneManager.GetActiveScene().name SceneManager.LoadScene(currentSceneName) void OnMouseDown() GetComponent lt SpriteRenderer gt ().color Color.red private void OnMouseUp() GetComponent lt SpriteRenderer gt ().color Color.white Vector2 directionToInitialPosition initialPosition transform.position GetComponent lt Rigidbody2D gt ().AddForce(directionToInitialPosition launchPower) GetComponent lt Rigidbody2D gt ().gravityScale 1 birdWasLaunched true private void OnMouseDrag() Vector3 newPosition Camera.main.ScreenToWorldPoint(Input.mousePosition) transform.position new Vector3(newPosition.x, newPosition.y) This the 2nd script to duplicate the bird but i'm not sure what the correct codes I have to put in if the 1st game object destroy, then it duplicate 2 bird? using System.Collections using System.Collections.Generic using UnityEngine public class Explode MonoBehaviour public GameObject Bird Update is called once per frame void Update() (if Destroy(Bird)) GameObject BirdClone Instantiate(Bird) |
