0 | Wrong Second position of LineRenderer I'm drawing some kind of bullet trace effect with LineRenderer in my 2D Game Project with Unity. At some position, setting position of LineRender result weird In the above screenshot, you can see two types of lines are exists. Pure red lines are result of Debug.DrawRay which is only renders in Scene view, not actual game play, and another lines which has yellow to red gradient are actual line renders I want to draw. I used exactly same code for rendering both two, Debug.DrawRay() and LineRenderer.SetPosition(), but as you can see only DrawRay works as I expected and LineRenderers are cutted and pointing wrong direction. Here's the code I'm trying void Fire() Vector3 shootDirection m ShootPoint.right RaycastHit2D hit Physics2D.Raycast(m ShootPoint.position, shootDirection, m Range) Debug.DrawRay(m ShootPoint.position, shootDirection.normalized m Range, Color.red, 20) On Hit, set end position where it hits if (hit) CreateBulletTrace(m ShootPoint.position, hit.point) Otherwise, render straight until it's range else CreateBulletTrace(m ShootPoint.position, shootDirection.normalized m Range) void CreateBulletTrace(Vector3 startPos, Vector3 endPos) GameObject bulletTraceObj Instantiate(m BulletTraceLineRendererPrefab) LineRenderer bulletTraceLineRenderer bulletTraceObj.GetComponent lt LineRenderer gt () bulletTraceLineRenderer.useWorldSpace true bulletTraceLineRenderer.SetPosition(0, startPos) bulletTraceLineRenderer.SetPosition(1, endPos) Destroy(bulletTraceObj, 0.1f) Note that LineRenderer checked use world space to true. What am I missing? Using Unity 2019.1.0f2. |
0 | A canvas to let through a given layer I have two canvases, both of them having a UI element on them. At some point, both canvases will be active in the game (I just act like so, I want to make sure that my game works even if that's the case) and I want one of them to never block the other canvas's layer. These two, let's say Canvas1 is on layer UI and is responsible for character jumping. Canvas2 is on layer toggle time scale and it's job is to switch between timescale 0 and 1. I want Canvas2 to be ALWAYS accessible, so its layer, toggle time scale is NOT blocked by the first canvas. I tried messing around with the Blocking Mask but that didn't help, sometimes the ray still gets blocked out. How to set up those Blocking Masks for my canvases to work? |

0 | Do realtime reflection probes and precomputed GI work on iOS in Unity 5? Seems they don't from my tests but just to double check. My setup is made up of a few objects marked as static, all sharing a standard shader material with some emissive color, GI set only to precompute and a realtime reflection probe (set to render on every frame) attached to the player, which is the object that moves and passes near the emissive objects. The player has a metallic material, also standard shader based. In the editor, this generates reflections on the player as it passes near an emissive object, as you'd expect. On iOS, the player looks dull, very dark, and no reflections appear on its surface. I also tried setting instead the probe to Custom and tell it to render from within a script, since I can't just pre bake the probes, because the static objects are brought in at runtime. This doesn't seem to work either the probe doesn't seem to render anything. Any ideas? |
0 | Objects rendering only on editor, but not on build (they get invisible) Everything works fine in the editor, but when I build the game, none of the objects in the scene are rendered, and only the skybox and UI text is visible. But although they aren't appearing, they are working as normally (i.e. these objects' triggers work normally when the determined event occurs, like for example, colliding to a specified object, or in other words, they are invisible). I searched for this issue but didn't found any answer. Could it be my cheap computer's fault (Intel Celeron without an external graphics card)? In editor game mode In buit game I ran both the editor and the built game in the same quality, and also tried to run it in Fastest quality, but no, it made no difference in the built game. Also, there is no object tagged with "Editor only", only one have a custom tag and all the others are "Untagged". And the camera's culling mask is set to "Everything". The result is the same either for web or Windows. Edit OK, I built for Android and the objects render normally. So, I'm not completely sure, but probably it's my PC that can't render the objects, because both building for web plugin and desktop have this disappointing result, but for Android it works perfectly (even the shadows, which wasn't being cast in the editor), so... |

0 | How do I draw a tilemap within unity3d? I'm pretty new to Unity and after a bit of googling around I have come up with this code to draw my tilemap (the script is attached to my camera). I am simply trying to use nested for loops to draw a grid of grass tiles, here is my code public class DrawMap MonoBehaviour Use this for initialization void Start () Sprite grass (Sprite)Instantiate(Resources.Load("Grass")) float x, y for (int i 0 i lt 20 i ) for (int j 0 j lt 20 j ) x i 1.28f y j 1.28f Instantiate(grass, new Vector3 (x, y, 0f), Quaternion.identity) Update is called once per frame void Update () I keep getting an error where I initialize "grass" saying the it cannot cast the source type from the destination type. I created "grass" to be a prefab from a slice of a spritesheet that i imported. Any help would be greatly appreciated |
0 | Unity2D How to destroy spawned object once it exit out of camera's view? I'm trying to destroy spawned objects once it exit out of camera view automatically straight away. You see I'm trying to make a flappy brids type of game but things also comes in from the bottom and if they get a really high score then things will be spawned in from above and from the left side. So, so far this is what my game looks like (I'm still working on it). However I'm having problems with deleting spawned objects once it exit out of camera's view, I tried all sorts of things like private var hasAppeared boolean function Start () hasAppeared false function Update() if (GetComponent. lt Renderer gt ().isVisible) hasAppeared true if (hasAppeared) if (!GetComponent. lt Renderer gt ().isVisible) Destroy(gameObject) But with this script, it doesn't destroy the game object quickly enough that and only some of them is being deleted. I also tried this method public void OnBecameInvisible() Destroy(gameObject) But not all of them is being deleted as well and it also takes a long time for any of my game objects to be destroyed. My last result was this script, it destroys the game object straight away once it exit out of the camera's view (which is what I want) but only these sides works where as the other's don't, I think it destroys my enemies (spawned objects) before it has even entered the camera's view. How do I get the script to work on this side? This is my script void Update () DestroyAllEnemy () public void DestroyAllEnemy() GameObject enemies GameObject.FindGameObjectsWithTag ("enemy") if ((enemies.Length gt 0) amp amp (camera ! null)) for (int i (enemies.Length 1) i gt 0 i ) just a precaution if ((enemies i ! null) amp amp ((camera.WorldToViewportPoint (enemies i .transform.position).x gt 1.03f) (enemies i .transform.position.y lt 6f))) Destroy (enemies i ) Thank you ). |
0 | Getting neighbors of hex tiles in 3D space I have a hex tiled model like attached below. Each of the hex tiles are separate objects meaning I can access each of the hex tiles individually inside Unity Now in my program I want to be able to get the 6 neighboring tiles of the selected tile. At first I thought I would get the 6 edges of the current tile and then check to see if any of the remaining tiles have those edges in common but that would be very expensive if I want to compute neighbors of all the tiles. Any ideas?? |
0 | Unity Editor Get Mouse coordinates on left click on Scene Editor I need a simple script which does the following When I left click somewhere in the Editor Scene (doesnt matter if there is an object under the cursor or not) Do NOT deselect the current selection in the Inspector. Do not select the object under the cursor. and Just print the mouse X and Z interception with the Y Plane in the Debug.Log() i stumbled on many solutions but somehow i couldnt get this to work. i tried HandleUtility.AddDefaultControl(GUIUtility.GetControlID(FocusType.Passive)) and Tools.current Tool.None both seem to do nothing ..... X.x EDIT Happens that "HandleUtility.AddDefaultControl(GUIUtility.GetControlID(FocusType.Passive)) " needs to be inside public void OnSceneGUI() and called every frame to "block" the mouse clicks on the editor. i thought it toggles it off. still the problem of the mouse coordinates persists. |
0 | Why is Particle System Not Visible Without Scene Window Viewing the Origin? I have a particle system, which is supposed to be highlighting an important game object, but the Particle System doesn't show on the game window unless the Scene window camera has the Origin (0,0,0) in view. The origin is at the corner of my UI canvases, in which you can see the two white lines marking the edges. Take a look at these screenshots. On the 1st screenshot, the particle system is not visible. The 2nd screenshot was taken just moments later and the particle system is completely visible (and the number of particles is as if it had already been emitting the whole time.) The only difference is that I slightly rotated the camera of the Scene Window in between screenshots. The camera was rotated down just a tiny bit to put the origin visible in the scene view. The particle system immediately becomes visible on the game window as soon as I rotate the SceneView camera so that the Origin is in view. This is Unity version 5.6.0f3. There are other questions about particle systems not working, but the cause and solutions appear to be very different. Here are things I've already tried The particle system is already set to "Play on Awake" both before and after rotating the camera. I've ensured that all of components and game objects are visible and enabled both before rotating toward the origin and after. All of the particle settings (size, etc.) are correct both before rotating to the origin and after. Why is the particle system not visible without the origin in the scene view? |
0 | 360 Orbital Camera Controller I have a stationary cube in my scene that I'm orbiting a camera around. I have my MainCamera nested under a GameObject that I'm calling 'OrbitalCamera'. I setup the script so that a click (or tap) and drag will rotate the camera around the object in space so it feels like you're rotating the cube (ie if I click the top of a face on the cube, and pull down, I'm rotating the X value) but you'll actually be rotating the camera. For the most part, my script works. However, after rotating the Y so much, the camera is upside down and the X gets inverted. Here's my script public class OrbitalCamera MonoBehaviour public bool cameraEnabled SerializeField private float touchSensitivity SerializeField private float scrollSensitivity SerializeField private float orbitDampening protected Transform xFormCamera protected Transform xFormParent protected Vector3 localRotation protected float cameraDistance void Start () cameraEnabled true xFormCamera transform xFormParent transform.parent cameraDistance transform.position.z 1 void LateUpdate () if (cameraEnabled) TODO FIX PROBLEM WHERE WHEN CAMERA IS ROTATED TO BE UPSIDEDOWN, CONTROLS GET INVERSED if (Input.GetMouseButton(0)) if (Input.GetAxis("Mouse X") ! 0 Input.GetAxis("Mouse Y") ! 0) localRotation.x Input.GetAxis("Mouse X") touchSensitivity localRotation.y Input.GetAxis("Mouse Y") touchSensitivity Quaternion qt Quaternion.Euler(localRotation.y, localRotation.x, 0) xFormParent.rotation Quaternion.Lerp(xFormParent.rotation, qt, Time.deltaTime orbitDampening) Is there a good method to achieve this type of 360 camera? I'd like dragging from right to left to always move the camera left and dragging left to right to always move the camera right no matter how the camera is oriented. |
0 | Too Low Amount of Tris in Statistics Window, Only in the Tens (Unity) I'm working on a mobile game, and for optimization it would be useful to see the correct amount of polygons rendered.

0 | Top down off screen indicator, Unity3D C I'm working on a top down 3D game where things spawn off camera. Movement only occurs on 2 axis (x and z). Rotation is about y axis. The player is in the center of the camera and needs to have indicators at the edge of the screen to show where the item is relative to the players location. I've managed to figure out the distance from my player to the target just using the distance between 2 Vector3 points. However, I can't figure out how to translate this into a direction angle for an indicator arrow that I have instantiated as a child of the canvas UI and make it point to the edge of the screen. |
0 | How to divide sprite sheet, but keeping the in same png? first post here, but couldn't find an exact answer in your database, so guess I'll have to ask.

0 | Unity Change Text with Time (Text Flashes) I am trying to display instructions within the Unity game. The idea is to have the instructions appear over time. For example, "instruction 1" then wait 5 seconds and show "instruction 2" instead of instruction 1 (on the same spot, in this case, I am changing the "message" variable in the code to change the instructions). This code does change the instructions but the problem is that it does it in a haphazard fashion. It appears that "instruction 1" is replaced with "instruction 2" and then it reverts back to "instruction 1" within a second and then back to "instruction 2" so instead of just 1 appearing 1 disappearing 2 appearing etc in a smooth fashion, it does this weird flashing thing before proceeding to the next instruction. How could I fix this? using UnityEngine using System.Collections using UnityEngine.UI public class Growing MonoBehaviour public Text instructions public string message void Start () instructions.text message void Update () Instructions() other code to begin moving a game object IEnumerator Instructions() run instructions message "GET READY FOR YOUR FOCUSED BREATHING EXERCISE" yield return new WaitForSecondsRealtime(5) message "MAKE SURE YOUR BODY IS COMFORTABLE" yield return new WaitForSecondsRealtime(5) |

0 | Get object length and width divided by two? I have googled and found a script for the following task Make the camera move to touched position. However, this script will jump to x and y positions on an object, while i would like for it to move to the middle of the object, and then only be able to jump to others. using UnityEngine using System.Collections public class TapToMove MonoBehaviour flag to check if the user has tapped clicked. Set to true on click. Reset to false on reaching destination private bool flagTouchCoords false destination point private Vector3 cameraDestination alter this to change the speed of the movement of player gameobject public float duration 100.0f vertical position of the gameobject private float yAxis void Start() save the y axis value of gameobject yAxis gameObject.transform.position.z Update is called once per frame void Update() check if the screen is touched clicked if ((Input.touchCount gt 0 amp amp Input.GetTouch(0).phase TouchPhase.Began) (Input.GetMouseButtonDown(0))) declare a variable of RaycastHit struct RaycastHit hit Create a Ray on the tapped clicked position Ray ray for unity editor if UNITY EDITOR ray Camera.main.ScreenPointToRay(Input.mousePosition) for touch device elif (UNITY ANDROID UNITY IPHONE UNITY WP8) ray Camera.main.ScreenPointToRay(Input.GetTouch(0).position) endif Check if the ray hits any collider if (Physics.Raycast(ray, out hit)) set a flag to indicate to move the gameobject flagTouchCoords true save the click tap position cameraDestination hit.point as we do not want to change the y axis value based on touch position, reset it to original y axis value cameraDestination.z yAxis Debug.Log(cameraDestination) check if the flag for movement is true and the current gameobject position is not same as the clicked tapped position if (flagTouchCoords amp amp !Mathf.Approximately(gameObject.transform.position.magnitude, cameraDestination.magnitude)) amp amp !(V3Equal(transform.position, endPoint))) move the gameobject to the desired position gameObject.transform.position Vector3.Lerp(gameObject.transform.position, cameraDestination, 1 (duration (Vector3.Distance(gameObject.transform.position, cameraDestination)))) So this is how the game looks. The script moves correctly, but will jump at different positions when it hits the collider on the lily pads. I could reduce the collider, but I feel like there should be an easy way to get length and width of a collider, and reduce it by 2 to make the camera move directly in the middle. Anyone care to help? Thanks in advance. ) |

0 | Handling an item database with procedurally generated items? Let's say you have an item database which has every item in your game. This works fine for regular items like a Health Potion, a normal Iron Sword etc, because these items have ItemID's so we can get an exact copy of this item. But what if we have an Iron Sword with an enchantment ' 5 Fire Damage'? (or whatever) If you were to save that item to a player's inventory, exit the game and load the game, the item will load as a regular Iron Sword, because it still has that ID. Specifically, how would you save that item to a file? I'm using Unity, so to save the Player's inventory, I use PlayerPrefs.SetInt("Inventory " i, inventory i .ItemId ) Would you create a custom item ID for every item with enchantments or is there a better way around this? |
0 | Rotating a gameworld using quaternion I'm a hobbyist programmer at best and I had an idea I wanted to test in Unity, I wanted to rotate the game world around 90 degrees, to this end I've been learning a tiny bit about quaternions, in this simple test I have a empty game object at position 0,0,0 and 2 cubes placed so only one will be in the foreground at once (both children of the empty game object). I simply want to rotate the parent object on a mouse up like so. if (Input.GetMouseButtonUp(0)) Quaternion newrot Quaternion.Euler (0,90,0) transform.rotation Quaternion.Slerp (transform.rotation,newrot,0.05f) The problem I am having is that this does not do the rotation in a single click and never reaches 90 degrees, it only ever tends towards 90 (for fun I decided to click for 2 minutes and only got up to 89.99999 ... well you get the picture). Can someone tell me what I am doing wrong and if there is a better way of doing this? |

0 | How can I tell if a Gameobject is currently touching another Gameobject with a specific tag? I've seen similar questions to this here on Stack Exchange Game Development, but none of the answers to them have helped my problem. I am working in Unity 2019.2.18f1 with Visual Studios 2019 Community. What I want to know how to tell when one Gameobject (the player) is currently touching another game object with a tag name of "Block". When the player collides with a "block" I want it to set jumpPossible true But when it leaves the block (by jumping or falling off) jumpPossible false What I currently have in my PlayerController script (the important stuff anyways) private void OnCollisionEnter(Collision collision) if (collision.gameObject.CompareTag("Block")) jumpPossible true private void OnCollisionExit(Collision collision) if (collision.gameObject.CompareTag("Block")) jumpPossible false The problem I am having is when the player is currently on a block and then touches another block. When it leaves the one of the blocks, it will set jumpPossible false and so you can't jump. What I want for this script to do is whenever the player is touching any Gameobject with a tag of "Block" it should allow it to jump. |

0 | ToonRamp Shader Normal Maps How to keep strict lighting bands? I'm trying to achieve a shading similar to the one on this image Image 1 https imgur.com a eTTvSCD To get something similar to this I wrote a toon ramp shader (similar to the one in the Standard Assets) with normal maps.

0 | RTS Unit AI When to let the unit stop (due to local avoidence) I am developing an RTS like game, that have units that move and attack. I implemented path finding and local avoidance. One problem is when multiple units being ordered to the exact same position, they can never reach the position due local avoidance and collision. Only this will make the units scratch each other, this will also cause the unit not able to STOP, as the unit might be still far from the target position. And whether stopped or not is important for battle (unit can only attack when stopped). I studied how SC2 handles this, it appears that the units will stop after a few seconds of scratching. PS, I have used group formation to avoid the situation, but it can not be avoided, when the group are ordered to goto some impossible position, and they would cluster at the edge of the valid navmesh. |

0 | Move a ball horizontally left and right but restricting forwards and backwards motion unity 2d I am trying to develop an endless runner where there is a sphere as the player and it is moving left and right following the position of a finger on a touch screen. However, when I try to do this I cannot get the player to lock on the Y axis. I want a constant force that speeds up overtime which I have using the constant force 2d supplied by unity.

0 | Simple Line Formation I'm working on the first formation for my game's troops. These should simply stand on land, facing the same direction. To achieve this, I tried to create offsets towards a pivot unit, that is approximately the unit in the center of the formation. The units are (temporary) elements of a squad list withing the Squad class. I divide the List by 2 and get the closest integer, that should be the pivot point of the formation. Now I generate offsets for all units on the left side (Unit 1 to pivot 1) and right (pivot 1 to last unit) based on the distance gaps. This is the code for the line formation. Sadly, the units are only forming a very stange line with no visually detectable system int count (int)(squadMembers.Count 2) pivot squadMembers count center pivot.transform.position switch (type) case FormationType.Line int space 5 for (int i 0 i lt squadMembers.Count i ) Unit tmp squadMembers i int dist 0 if (i gt count) dist (count 1) space center.x dist if (i lt count) dist (count 1) space center.x dist tmp.StartMove(center) break It also appears that this only works along the x axis, any idea how i can realize this with the walking facing direction ov the pivot? Is there any (obvious) error? How can I improve this script? PS Any idea, how I can transform this into a double line (2 Lines behind with half spacing) |

0 | How to make an object that has no rigidbody2d component smoothly fall on the ground in Unty2d? I have two character in my game enemy and main character. Enemy can throw different objects into the main character. For this moment i am doing this action in such way void FixedUpdate() if (CanMove) transform.position Vector2.MoveTowards(transform.position, TargetPlayer.transform.position, 15 Time.deltaTime) public void StartMove(bool canMove) CanMove canMove TargetPlayer GameObject.FindGameObjectWithTag(Tag).transform rigidbody2D.gravityScale 0 This script is attached to the prefab of the object that will be thrown into main character by the enemy. This script is working, but in this case the object that was thrown will follow by main character all the time, because of this line of code transform.position Vector2.MoveTowards(transform.position, TargetPlayer.transform.position, 15 Time.deltaTime) To my mind this is not good, because i want to give my player the opportunity to escape from the object that was thrown at him. For example run away. When the object reaches the player position (and the player is on the new position) he will simply fall onto the ground. I did this, but this wasn't looking nice, because when the object was reaching his position, he was hanging in the air. Can anyone give me an advice how to make this process more good looking? Edit I need to make good looking movement of the object, that was thrown by the enemy into main character. Every frame i am moving the instantiated object to the current player position. So the player can't escape from that object, because he always knows current player position. I think that this is not good idea, and i want to give to player an opportunity to run away from that object. In this case i am saving the position of the player into variable, and then every frame i am moving the instantiated object to that position. So when the player run away, the object, that was thrown doesn't know anything about new position of my player. But this is looking not good, because when the object is reaches its destination position he hangs in the air(( Edit 2 I was thinking about destroying that object anyway, but to my mind this will not look good the object is moving and suddenly disappears from screen(. May there is some ways how to make him smoothly fall onto the ground? The problem is in that this instantiated object has no Rigidbody2d component attached to it, so it will never fall down by itself. |

0 | Get rotation of camera in Google VR I'm trying to move child of camera object smooth. To implement that, I need to know the movement of x and y axis, like Input.GetAxis in general PC platforms. I saw the documentation and examples of Google VR, but there's not much explained well. One thing I found is GvrControllerInput.Gyro, but it's said it's deprecated and use GvrControllerInputDevice.Gyro instead, but there's no Gyro value in GvrControllerInputDevice. Seems like basic usage is totally changed, so they are not providing static methods, and force to using internal method of the object, but couldn't find any related information about this. So, how do I get gyro from GvrControllerInputDevice? Or is there an alternative way to make child object rotate smooth from their parent? Any advice will very appreciate it! |
0 | Set Layer of UI Object being Dragged In my game, I have an inventory system with slots and images in those slots. The images are by default disabled, but when an item is added to the slot, the image component becomes enabled. I have implemented a very simple drag and drop system for moving objects around in the inventory using IBeginDragHandler, IDragHandler, and IEndDragHandler. As I am dragging an item from one slot to another, I want the item image to be rendered in front of the slots and the rest of the inventory. Currently, when dragging an item image, it renders behind the empty slots. I don't want to use hierarchy order to organize the layers of these slots because moving items around is very dynamic and the hierarchy order of the slots changes seemingly randomly when I press play. Is there another way to ensure that the item image being dragged is "closer to the camera" or in front of the rest of the inventory? Thanks. |
0 | How to revert to MonoDevelop's old "ctrl tab" behavior? I believe MonoDevelop (bundled with Unity3D) has changed its ctrl tab and ctrl shift tab behavior and I would like to get back to the old behavior, as the new way frustrates my workflow. Ctrl tab (and ctrl shift tab) previously (and ought to) go to the "last viewed tab", in a similar way to how alt tab works on Windows. Unfortunately there seems to have been a change and now it goes to the "tab on the left of the current one". An example of why this is frustrating quickly looking at a class definition, you hit F12 to load the definition (perhaps in a new tab), and then you want to go back to the code you were working on. Previously you could hit ctrl tab and you'd be back there. Now you can't do that and you have to actually remember what you were doing, which isn't good for my workflow (read ailing memory). I'm not sure when the change happened, or if it's a setting somewhere (I can't find it). I'm running Unity 5.1.2p2 and its bundled MonoDev 4.0.1. Noticed it after a clean install of Windows 10. How can I fix this to revert to the old behaviour, or is there some other method to jump back to the last viewed tab? It seems pedantic but it has a major impact on my productivity. |

0 | Unity Disable push on dynamic Rigidbody2D objects I have a player, and several NPCs. I also have several static colliders in the world (trees, water, fence, etc), I want my NPCs to collide with this, so the Rigidbody2D needs to be dynamic, since kinematic does not collide with static colliders (colliders without a rigidbody). My problem is that since both player and NPC have dynamic rigidbodies, they push each other when they collide. I could disable this by setting the following in the NPC script void OnCollisionEnter2D(Collision2D other) if (other.gameObject.name "Player") isMoving false myRigidBody.isKinematic true However, the NPC still gets pushed a few pixels before it stops, its barely noticable, but it is noticable, and if you keep colliding with the NPC you could move it as far as you wanted (tedious, but possible). I've spent a few hours looking and cannot find a good solution to this. I want my NPC to collide with static colliders, but I don't want them to get pushed by the player. How can I solve this? |

0 | Unity Smooth collision I'm making a topdown 2D RPG in Unity. All moveable objects have Rigidbody2D components with gravity set to 0, linear drag set to 5 and different masses. Walls are stationary boxes with BoxCollider2Ds. Here's my problem http a.pomf.se nifmcn.webm The rock is not particularly easy to see, but if you watch when I'm trying to walk into a wall, the player kind of jags in and out of the wall. Of course, this is because I'm moving the player by moving it's Rigidbody2D, for example rigidbody2D.transform.position Vector3.up Time.deltaTime speed The box then throws the player in the opposite direction of what he was going. What's a good way of stopping a player from moving in the direction he's trying to go? More specifically, how do you detect which way he's going? Do you find the angle between the player and the object wall? This is kind of an open question, but I think it's extremely important. |
0 | 2D physics without "rebound" I'm trying to get my 2D top down shooter to use some physics. I want the player and enemies not be able to exist in the same position, in other words, use collisions. My first attempt was to use a CharacterController, but I could not get my other game objects to collide with my player, even though I had a RigidBody2D and a BoxCollider2D on them. Obviously, due to using a CharacterController, I was not able to add these components on my player. Going one step back, I removed the CharacterController, and rather opted to go the Rigidbody2D route. This worked partially. I now get collisions on my player when he walks into other gameobjects (with RB2D and BC2D on them), but there seems to be a quot rebound quot anomaly occurring my player moves around after collision. I've tried playing around with the settings on the RigidBody2D on the player, but it does not seem to have any effect.

0 | Causing Update loop with Coroutine Unity Total Noob Alert! lt 7 days with C and Unity My Win Game screen becomes SetActive and my Player is SetActive false when you are standing in a trigger and crouch. That all works fine except you cant see the crouch animation because he is IMMEDIATELY SetActive false. I tried to delay this by creating a coroutine. The problem with that is this is all happening in the Update function (or whatever it's called) because of the getkeydown for crouch. That gets called once per frame so my coroutine is trying to go off once per frame. I tried creating a bool called isCoroutineStarted and set it to false and then set it to true in the Coroutine to break the loop but that didn't work either. Don't know what to do so I reverted it back to before where it doesn't show my crouch animation.

0 | "Hold to jump higher" suddenly outputs a much higher jump I'm programming my first game in Unity and I'd like to make a very controllable jump. The idea is to apply an upward force while the player is still pressing the jump button, and then after some time ignore jump input. Kinda like how Mario and Mega Man jump. Problem is, somehow, my character occasionaly jumps much higher than it normally does. I set three variables on the inspector jumpImpulse the initial speed after pressing the jump button riseAcc the acceleration applied to the character while holding the jump button maxJumpHoldTime the longest possible time one might hold the button while still rising. if ((onGround onPlatform) amp amp Input.GetButtonDown("Jump")) GetButtonDown prevents holding jump and keeping jumping rb.AddForce(Vector2(0,(jumpImpulse rb.mass)), ForceMode2D.Impulse) force that starts the jump itself. rb.mass makes F ma into F ma m gt F a, so "Force" is actually acceleration. This is to better control mass and jump mechanics. jumping true DEBUG debugJumped true if (jumping amp amp Input.GetButton("Jump")) rb.AddForce(Vector2(0,(riseAcc rb.mass)), ForceMode2D.Force) first acceleration jumpHoldTime Time.deltaTime if (jumpHoldTime gt maxJumpHoldTime) jumping false else jumping false jumpHoldTime 0 Made this so I know how high the character jumps. if (debugJumped amp amp (!onGround) amp amp rb.velocity.y lt 0) Debug.Log ("Jump height is " transform.position.y) debugJumped false In the console, the jump height is listed normally as 2.376213, but sometimes it appears as 5.008272. It appeared once as 2.377432. Also, this variation seems to appear more frequently when I'm also moving the character left or right. And I'm not sure if this is related, but there are many times when I press the jump button and the character simply doesn't jump. Also, I put everything here under the FixedUpdate function. |

0 | Unity sprites are no longer batched after the object rotates moves With Unity 5 and access to the profiler, I'm running our game through some stress tests so I can find where our performance issues are. While testing having 1024 units on the screen with 4 selection box corners each I ran into an odd problem. When I select all the units, 4096 selection box objects come into existence, my draw calls go from 25 to 50 with 50 batches. Now when I tell the units to move, they rotate and the number of batches climbs up to 2090 and the draw calls climb to 2090 and stay there even after the units stop rotating or moving. If I then reselect all the units, the selection boxes are destroyed and re instantiated (I know, not the best way) and the batches and draw calls go back down to 50 from 2090. What is causing this, and how would I go about fixing it? After Selecting All Units After having them rotate and move After Re selecting Them All |

0 | How to optimize two pass operations on an array with Unity Coroutines I am working on simulating vacuum decompression in a 2D top down environment. I have 2 2 dimensional arrays one that stores the pressure at a location, and one that stores the vector of fluid flow. The algorithm looks likes this private void Flow() Diffuse() Vectorize() private void Vectorize() for(int x 0 x lt xRange x ) for(int y 0 y lt yRange y ) float myPressure pressure x,y ... Vector2 flowVector calculate the resultant vector from the pressure differentials O(1) op ... vector x,y flowVector private void Diffuse() for(int x 0 x lt xRange x ) for(int y 0 y lt yRange y ) float myPressure pressure x,y ... float newPressure calculate the new pressure from the pressure differentials O(1) op ... pressure x,y newPressure The problem is that as the area of the simulation space increases, the performance continues to drop off as the iteration steps block the update loop. I want to convert these to Coroutines in such a way that both yield but more or less maintain a lockstep appearance. Since flow is dependent on pressure differential, and pressure differential is partially dependent on flow, if an order has to be enforced, then Diffuse should take precedence. My initial attempt followed the following form IEnumerable Flow() StartCoroutine(Diffuse()) yield return null StartCoroutine(Vectorize()) IEnumerable Vectorize() for(int x 0 x lt xRange x ) for(int y 0 y lt yRange y ) float myPressure pressure x,y ... Vector2 flowVector calculate the resultant vector from the pressure differentials O(1) op ... vector x,y flowVector yield return null IEnumerable Diffuse() for(int x 0 x lt xRange x ) for(int y 0 y lt yRange y ) float myPressure pressure x,y ... float newPressure calculate the new pressure from the pressure differentials O(1) op ... pressure x,y newPressure yield return null This tended to cause a jittery simulation. Even on a small 20x20 simulation field, there was noticeable difference between the first and second solutions. Are there any tricks to coroutines that will allow a more lockstep simulation that scales well? Any suggestions on optimization is welcomed as well. |

0 | How to make AI detect a target behind a wall, who is only partially exposed? I'm making an FPS game where, even when a target's whole body is behind a wall or box, but its finger or foot exposed, the AI should be able to detect it and shoot its finger. So far the way I've thought of to implement this it so traverse all the targets, find who is near a wall, and compare their position with the corner of wall. But I don't know how to check whether its finger is exposed. I could use a raycast forward from the AI's gun, but would I need to add a collider to every small body part of every target? |

0 | How to blend motions with Mecanim I'm struggling with Mecanim. My concern is to blend straight turning animations with strafe animation for a humanoid character.

0 | Detecting mouse clicks in Unity UI Beta I want my game script to detect mouse clicks everywhere on my screen, except one corner where I have a pair of buttons to control the sound and will be handled separately. To help identify this corner, I've created a soundPanel object with the Rect Transform component (available in the Unity 4 Beta 17 ) and have sized positioned it appropriately in the editor in my UI layer. In my game's script, I have passed in this corner object, and tried using it in the following way bool tap (Input.GetMouseButtonDown(0) Input.GetMouseButtonUp(0)) amp amp !soundPanel.rect.Contains(Input.mousePosition) Clicking in the soundPanel still triggers a tap. I figured this is because the mouse position and soundPanel.Rect are not in the same coordinate space. Since the documentation on the new Unity Beta UI is a bit lacking hard to find, I tried converting the mouse coordinates to everything I could if (Input.GetMouseButtonDown(0) Input.GetMouseButtonUp(0)) if (soundPanel.rect.Contains(Input.mousePosition)) print("Raw") if (soundPanel.rect.Contains(camera.ScreenToViewportPoint(Input.mousePosition))) print("ScreenToViewportPoint") if (soundPanel.rect.Contains(camera.ScreenToWorldPoint(Input.mousePosition))) print("ScreenToWorldPoint") if (soundPanel.rect.Contains(camera.ViewportToScreenPoint(Input.mousePosition))) print("ViewportToScreenPoint") if (soundPanel.rect.Contains(camera.ViewportToWorldPoint(Input.mousePosition))) print("ViewportToWorldPoint") if (soundPanel.rect.Contains(camera.WorldToScreenPoint(Input.mousePosition))) print("WorldToScreenPoint") if (soundPanel.rect.Contains(camera.WorldToViewportPoint(Input.mousePosition))) print("WorldToViewportPoint") print(" ") When I click with the above code, "ScreenToViewportPoint" and "ScreenToWorldPoint" print no matter where I click, and no others trigger. I suspect I need to transform the soundPanel somehow. Here is the Hierarchy, Scene, and Inspector. The selected rect is the soundPanel, and it is in the bottom right of the UI Canvas |

0 | OnTriggerExit() called when game object with collider component gets re parented I have an object Hand, with a rigid body attached to it. In every Update() call, the user's hand controller rotation and position are tracked. In my scene, there is an object Pin, with a mesh collider attached to it. In OnTriggerEnter() (inside the Hand class), Pin becomes re parented to Hand. (Pin's original parent is something else.) My scene also contains other objects with colliders. However, these other objects do not get re parented only Pin does. Once this re parenting takes place, OnTriggerExit() (in the Hand class) is called immediately. This is surprising to me I had expected OnTriggerStay() (in the Hand class) to be invoked instead, since Hand is still in contact with Pin. Is such behaviour by design? Is there an elegant way of working around such behaviour? UPDATE In response to this comment Does the pin object have a parent before it becomes a part of the hand? Yes. As mentioned in my post, Pin's original parent is something else. Or is it placed inside another collider? And does the pin leave any of these collider areas when the parenting takes place? As mentioned in my post, Pin itself has a mesh collider component attached to it. Perhaps I am not understanding the question correctly... You can prevent the hand's script from getting this OnTriggerExit by adding a seperate rigidbody to the pin. I added a separate rigid body to the pin (setting isKinematic to true), but OnTriggerExit() inside the Hand class is still called immediately after Pin gets re parented. MORE INFORMATION Pin's original parent (before it gets re parented to Hand) does not itself have a collider component. When OnTriggerExit(Collider collider) gets called immediately after the re parenting takes place, the collider argument passed to the method is the Pin itself. |

0 | Unity Setting up the Universal Rendering Pipeline for Layer Masking I've been watching this video about Field of View (Player) by CodeMonkey which explains on how to set up a scriptable rendering pipeline for the layer unmasking masking of objects. However, the interface changed with the latest updates. There's an Opaque Layer Mask and there's a Transparent Layer Mask. I've followed the Render Features as described in the video but I wasn't able to get the masking done correctly as there's these two options that I can't seem to figure out what it does. I tried toggling to and from layers to see which one is meant to be in the other one but this is the best I could get For simplicity's sake, these are the layers that I am using Characters (things I want to see when the Field of View mask is over them) player enemy friendly dead Field of view (the unmasking layer) Fog of war (the thing that makes everything have a black transparent fog) UI (the layer that I want to see regardless of the where the Field of view mask is) As of right now, I could see the Field of View and the UI. Everything else is missing. I have asked in their own community however, no one reached out to me. Let me know in the comments if you need more info. edit 1 to reproduce create the following layers (Player, Enemy, FogOfWar, FieldOfView, Wall, UI) Set a game object with sprite component to player, enemy. Set them to the Player and Enemy respectively. This one, we want to see if the field of view layer is on top of it. They will be invisible if the field of view is not on top of it. Place a Sprite Renderer (a square) and set it to the Wall. This one, we want to see regardless if it's masked or not. If the field of view layer is not on top of it, this should be darkened by the fog of war. Set a Mesh Renderer (A simple plane would do) to Field of view and set it above the player and enemy. Make sure the face of the plane is facing the camera. This object would reveal or hide the Player and the Enemy layer. If this is on top of the FogOfWar, the area that the FieldOfView is upon will be invisible. That way, the sprites underneath it is not darkened. Have a sprite renderer (A square) and set it to black with 50 opacity and make it cover the the Player, Enemy, and FieldOfView. Set this to FogOfWar Create a button, and set it to UI layer Create a universal rendering pipeline. head over to the options and add the settings (keep in mind, I don't know what to set here. The Opaque and Transparent Layer Mask are my problem.) a. Opaque Layer Mask Wall, FogOfWar, FieldOfView b. Transparent Layer Mask Player, Enemy For the render features, add these three Behind Masks contain Player amp Enemy edit 2 I forgot. I have three cameras. All orthographic. They only render a specific layer. Main Camera Culling Mask is Wall Character Camera Culling Masks are Player and Enemy UI Camera Culling Masks is UI Character and UI camera have a depth. UI Camera's depth is 0. Character Camera's depth is 1. I want to render the UI below the characters. Hence, I separated them into their own camera. |

0 | Same dimension feel no matter what FOV Does anyone know a formula, way, ... to make a FPS player feel like an object has the same size on different FOVs (given that it's at the same distance of the player, of course)? I know that this can't be done perfectly, because of the distortion various FOVs cause and the position of the object (near the edges of the FOV more distortion). Let's ignore these distortions, and aim for a same size feel for objects that are directly in front of the player (so in the exact center of the FOV). To clarify things a bit further I want 1 object in my game to have the same scale feel on different FOVs, not my entire game world. I've tried giving it a percentage of the frustrum height, but that doesn't seem to give me consistent results. Note I'm using vertical field of view in my game. |
0 | Unity3D C Drag object smoothly on it's x axis that's already bouncing In my scene, I have a bouncing ball that collides with a cube. On each collision the ball returns to the same height. How can I get the ball to smoothly move along the x axis by dragging my finger across the screen, while at the same time having no effect on the y or z values? The y position is changing every frame depending on the state of the jump, so setting it's y position to transform.position.y in the Update function causes the movement to be jittery if the frame renders when it isn't caught up with the position of the ball. Also, I set the interpolate value of the rigidbody to interpolate to get a smoother jumping motion, not sure if this is relevant to my problem or not. Here is where I am at so far with little success. A few mobile games that replicate what I'm trying to achieve in terms of ball movement are Hop, Color Hop, and Splashy! void Update() if (Input.touchCount gt 0 amp amp Input.GetTouch(0).phase TouchPhase.Moved) Control sliding using touch input.

0 | Unity Android Button Select (Highlight) by touch, before clicking I have a multiplatform game with dozens of buttons in many menus. I used the animated buttons setup to have a normal state and highlight state. Highlight will most of the time resize the button with a nice anim AS WELL as make a dedicated text box appear with extra information. So far so good. Everything works perfectly on PC. However, as I am testing my build on android, I cannot find how to access the "highlight" state since touching the screen click and it execute the on click () associated. What I need is a way to select a button when it is first touched, since selected highlight (somewhat) then if it is touched (clicked) a second time while selected then to do the on click ( ) function. I have a few theory on how to do it, but it would require recreating every of my 80 or so buttons as well as changing everything from using the Unity GUI system to make my own C version which would take weeks. I am also trying a few other way to achieve the same thing. One of which is using the "button.select()" to select the button on its first click. That works. problem is I cannot seem to write a way to do "if (thisbutton.IsSelected true)" that just refuses to work. |

0 | What determines the hit detection ordering for graphic elements in Unity (2d game)? I have a bunch of overlapping buttons spread across several UI Canvases. The default mouse behaviour only registers hover click events with one of the overlapping buttons, which is ideal for my project. The problem is the order of which button gets activated, is not tied to the Layer it is on or the Sorting Layer the item is on. I cannot seem to control which button is the top button that gets activated. Using a RaycastAll() function returns the name of all buttons on any given point, and reflects the problem that for some reason, the buttons are arbitrarily ordered. How do you control the order in which buttons are registered by the mouse? |
