0 | How to make pathways corridors in a randomly generated dungeon? I am trying to make a random dungeon generator using Unity. I have been able to setup the rooms properly and connect them to each other using a minimum spanning tree algorithm. I have attached an image below where you can see what I have so far. The next step will be to create pathways corridors to connect the rooms together but I am having difficulty understanding how I am supposed to go about it. I want the corridors to be straight or form an 'L' shape when connecting to each other. So I was wondering if anyone could help me out with this. Any help is appreciated. |
0 | How does Unity call "update()" in the scripts? I understand that you can expose your C code to a scripting language such as ChaiScript. From this you can call code that you've made in C . In Unity, however, they have functions in the script, such as Update() that get called. In other words, how do I call script functions from C ? |
0 | How to make an Assert.IsNull test pass when the value is reported as ? I've just started using unity tests with the built in editor tests. After making my test and finding out that it constantly failed I debugged the code and found that a static object was set to a new game object when running the test while it is set to null when playing in the editor. Is there a way to force unity to treat the test the in the same way that it treats scripts at run time? Edit After changing some code around i get another strange error does anyone know why "null" isn't "null". The null objects are stored in an array, but that shouldn't make a difference right? Edit Edit (Edit 2?) Here is the code that has the issue public class StatCollector MonoBehaviour public static StatCollector running ensure that there is only one object running at the same time public void Awake () if(running null) DontDestroyOnLoad(gameObject) running this else if(running ! this) DestroyImmediate(gameObject) and here is the test Test public void SingleTest() create gameobjects GameObject collect new GameObject 2 collect 0 new GameObject("one") collect 1 new GameObject("two") collect 0 .AddComponent lt StatCollector gt () see if gameobjects were created correctly if (collect 0 null collect 1 null) Assert.Fail("failed to create game objects") test what happens when the second stat collector is added to the scene collect 1 .AddComponent lt StatCollector gt () collect 0 .GetComponent lt StatCollector gt ().Awake() collect 1 .GetComponent lt StatCollector gt ().Awake() Assert.IsNull(collect 1 ) I'm assuming that there is no way to keep Awake private which is why it is public (just so that the test case has access to it) |
0 | Saving total play time could be fine? I'm making a game that needs to save total played time into file (using JSON) for comparing amp resolving data conflicts between local and cloud. I will override outdated one. Currently, I'm just adding Time.realtimeSinceStartup, but is that okay? What if the time is really, really big and couldn't be handled in Unity anymore? Could that eventually happen? If so, what are some alternatives? |
0 | Unity Z position issue on gameobject with subcomponents I'm following this tutorial from Ryan Miller on how to create a rig of sorts from a sprite atlas sheet.

0 | MCS character mouth open is this mo cap animation problem? I have MCS Female Character where I can assigned Mocap to my character. I have downloaded mixamo animation and assigned this to the character but the problem is, the character mouth remains open. I am not 3d artist or animation guy, so here are my question. How can I solve mouth open problem in unity? What is the reason that mouth is open? Either mocap data has open the mouth or what else problem? |
0 | Editing attached component property in Unity (C ) This might be more of a general C programming query, but since it's game dev related, I'm putting it here. I am trying to randomise a property in a custom component (C script) across several Unity game objects. hostiles is a list of game objects, each with an attached Stats component. foreach (GameObject gO in hostiles) Randomise spawn area gO.GetComponent lt Stats gt ().AreaNo Random.Range(0, 3) Perhaps unsurprisingly, all of my objects end up with the same value for AreaNo. It seems as though I m reassigning some global version of Stats.AreaNo in my loop, rather than the individual instances. What am I missing? (Sorry in advance for the noobish question!) |

0 | How can I instantiate enemies in a 2D game at a set Viewport Position before my camera enters the room? (Or alternative solution!) I'm currently working on a 2D game where I'm trying to pre populate my level with encounters, I want the enemies already in the room when the player enters. Right now the encounter is triggered upon entering the room when the camera bumps into the collider and the enemies are instantiated at the Viewport position, however because it does it while the camera is moving into the room the position is incorrect. Using hard values isn't an option because the maps could of course change and also I may want them randomly generated at some point. So I guess ultimately the problem is the camera not being in the right position when they instantiate and not wanting enemies to quot pop quot in once it is. Is there a way I can I instantiate an enemy at the same point on the screen regardless of resolution in each specific room at the start of the level? Encounters will have up to 3 enemies and they will always hold the same formation (with spots randomized to add diversity) Here is my instantiating code SerializeField public List lt GameObject gt levelEnemies new List lt GameObject gt () GameObject levelEnemy Vector3 enemyPosition Vector3 viewportPosition new Vector3(0.8f, 0.5f, 10f) Place on the screen I decided I want single enemies to appear Camera cam void Start() Debug.Log( quot Enemy Triggered quot ) cam Camera.main enemyPosition cam.ViewportToWorldPoint(viewportPosition) levelEnemy Instantiate(levelEnemies 0 , enemyPosition, Quaternion.identity) instantiate test enemy at the converted position navigation.DisableNavigation() Here is what my camera collider looks like (Room 1) and my enemy encounter collider looks like (Room 3) Here's what should be happening when the enemy is instantiated (triggered manually through the editor once camera has been moved fully) Here is what happens when the camera collider bumps into the encounter collider Any help in the right direction would be much appreciated or a workaround! Here is what my camera collider looks like (Room 1) and my enemy encounter collider looks like (Room 3) |
0 | Change texture settings for each object So I'm kinda new to Unity, but I've used it a couple of times before. Here's my issue I have two cubes with a random texture applied to them (drag'n'dropped something from the Asset Store). These cubes have different sizes, where one is a square and one is a rectangle. I want to set the tiling size to be different on them (because they are obviously stretched on the rectangle), but when I click on one and change it, the settings changes for both of them. This is how it looks right now http i.imgur.com JtubBle.png Is it possible to make these settings unique for each object somehow? |

0 | Uploading APK build to Google Play Console error "You uploaded a debuggable APK or Android App Bundle" I was trying to upload my andoid app apk build to my play console account and I keep getting this error You uploaded a debuggable APK or Android App Bundle. For security reasons you need to disable debugging before it can be published in Google Play. In accordance with the informations given at https developer.android.com studio publish preparing.html publishing configure and https answers.unity.com questions 1653647 you uploaded a debuggable apk or android app bundl.html Here are what I have done so far 1) I have gone to the root folder of my unity project, searched for AndroidManifest.xml, and I found multiple Manifest files, and changed the value of "android debuggable" to false for each of these manifest files that were generated by unity(and I did not edit the google generated manifest files). 2) I have scanned every c file on my project that contains the keyword "Debug" and I have either deleted or commented out the Debug.log lines except on the files generated by google(as a result of the integration of google play services into my game). And yet, I still have the same problem when I try to upload my apk to play console. What else am I missing? Should I also remove the Debug.log lines from google generated c script files? |
0 | SerializeField UntiyEvent not properly saving modifications in EditorWindow I'm making a node editor in Unity using an EditorWindow, I'm currently trying to make it so designers can add their own methods to a node using serialized UnityEvents but I haven't been able to get it to function properly. SerializedObject serializedObject new SerializedObject(selectedNode.NodeState) SerializedProperty property serializedObject.GetIterator() property.Next(true) while (property.NextVisible(false)) EditorGUILayout.PropertyField(property) serializedObject.ApplyModifiedProperties() serializedObject.Update() The above code runs through all necessary fields of the class so the user can modify them. Everything functions perfectly with the exception of UnityEvents. They almost do as I intend them to do, except they don't preserve the variable inputs of inserted object's method. If I keep working within the editor window they stay, but if I close the window and re open the inputted variable resets. I thought this may be caused by an issue somewhere else in my code, but all other fields work fine. |
0 | How to do collision detection in Unity between Character Controller, Rigidbody Collider and a NavmeshAgent? I would like to know more about how collision detection works in Unity especially when character controllers and NavmeshAgents get involved. For example, how can I detect collision between NavmeshAgent and a CharacterController? I have added a sphere collider to my NavmeshAgent, but it doesn't seem to detect a collision unless I set it to "IsTrigger". I have tried OnCollisionEnter(), OnControllerColliderHit() and OnTriggerEnter(). OnTriggerEnter() seems to be the only one that works and only when I enable "IsTrigger". How come the other two don't work? Shouldn't they? What if I didn't want to make the collider a trigger? |

0 | Unity custom shaders and z fighting I've just readed a chapter of Unity iOS Essential by Robert Wiebe. It shows a solution for handling z figthing problem occuring while rendering a street on a plane with the same y offset. Basically it modified Normal Diffuse shader provided by Unity, specifing the (texture?) offset in 1, 1. Here's basically what the shader looks like Shader "Custom ModifiedNormalDiffuse" Properties Color ("Main Color", Color) (1,1,1,1) MainTex ("Base (RGB)", 2D) "white" SubShader Offset 1, 1 THIS IS THE ADDED LINE Tags "RenderType" "Opaque" LOD 200 CGPROGRAM pragma surface surf Lambert sampler2D MainTex fixed4 Color struct Input float2 uv MainTex void surf (Input IN, inout SurfaceOutput o) half4 c tex2D ( MainTex, IN.uv MainTex) Color o.Albedo c.rgb o.Alpha c.a ENDCG FallBack "Diffuse" Ok. That's simple and it works. The author says about it ...we could use a copy of the shader that draw the road at an Offset of 1, 1 so that whenever the two textures are drawn, the road is always drawn last. I don't know CG nor GLSL, but I've a little bit of experience with HLSL. Anyway I can't figure out what exactly is going on. Could anyone explain me what exactly Offset directly does, and how is solves z fighting problems? |

0 | Local avoidance together with any angle types of A Pathfinding Recently I have been implementing the Block A any angle path finding algorithm in a project I have, for which I need extremely efficient results due to the large number of NPCs. However, I still do not know exactly how to handle the problem of local avoidance between the NPCs moving at the same time in the same scene. So, my question is this what is the best method to implement local avoidance with any angle path finding? Just testing for LOS and steering to the tangent of the predicted encounter is a good enough solution or should a specific AI implementation be included within the pathfinding routine? I would highly appreciate references (academical or not) with state of the art implementations of local avoidance for me to explore the most recent developments in that field. Many thanks. |
0 | Is it possible to have FixedUpdate execute once every n frames? I'm currently building a small game, and I've created this simple character controller using FixedUpdate, which executes every frame. using UnityEngine public class PlayerMovement MonoBehaviour lt summary gt Check for a key press, and if that key is pressed, move in a specified direction if there are no obstacles. lt summary gt private void MovePlayerOnKey(KeyCode keyCode, Vector3 direction) Collider hitColliders Physics.OverlapSphere(this.transform.position direction, 0.1f) if(Input.GetKey(keyCode) amp amp hitColliders.Length lt 0) this.transform.position direction lt summary gt FixedUpdate is used to ensure that the player is moving in sync with the step of the Physics engine, and not executing a variable amount each frame. lt summary gt public void FixedUpdate() this.MovePlayerOnKey(KeyCode.W, new Vector3(0, 1f, 0)) this.MovePlayerOnKey(KeyCode.A, new Vector3( 1f, 0, 0)) this.MovePlayerOnKey(KeyCode.S, new Vector3(0, 1f, 0)) this.MovePlayerOnKey(KeyCode.D, new Vector3(1f, 0, 0)) While the code itself works, the player moves much too fast for my liking, and I can't change the step of the player either, it has to stay at 1 in order for other game mechanics to function properly. The only solution I can think of is changing how FixedUpdate runs by running it less often. Is it possible to make FixedUpdate run once every n frames? |

0 | Collisions and Colliders Does anyone know how to prevent a gameobject from colliding with another gameobject but can still register collisions? Like a ball that can bounce off of the wall or ground and can pass through the player himself. What I have tried Creating two Colliders on the ball(which has a rigidbody component) and making one of them bigger than the other (and turn on quot Is Trigger quot on the bigger collider). Then write code in the OnTriggerEnter and the OnTriggerExit functions to disable enable the smaller collider so that the ball could fly right through the player. But that is completely useless when the ball is not in motion and the player walks over it(because it'll fall straight down through the ground). |

0 | UV mapping Untextured faces? Im currently trying to texture a (transparent) cylinder. I want the texture image to wrap sideways around the cylinder but not the top and bottom faces, they are supposed to just stay untextured (so transparent, in this case). So what I did (in Blender) is UV unwrap only the side faces and leaving the top and bottom faces as they are. However, this method doesn't seem to work very well, because when I import the .obj in Unity the top and bottom faces are mapped to a "random" place in the texture and therefore have color. My current workaround is to map the top bottom faces to areas in my texture that are transparent, however, this only works when textures have a transparent place, which isn't always the case. |

0 | Load all materials with loadallassetbundles before objects? I have a lot of objects as assetbundles and they're growing. I didn't want to have the user to download the materials for every asset because they all share their materials. so I put all the materials in an assetbundle and load it by LoadAllAssets() in the Awake() function so they are present in the game for the assets to use. The problem is that asset load without materials. the ones that have material don't have shader. Is LoadAllAssets() not the answer? what should I do? |
0 | Something is preventing my NavMeshAgent from moving I apologize for the vague title. I really wish I could ask something more specific, but I can't. I had my click to move script working fine with the NavMesh. I showed it to my colleague earlier today, and must have accidenntally made a change and saved. Now the guy's not walking. There are no errors and my debugging leads me to believe all code paths are working as expected. When I click on a location, it checks that it is valid on the NavMesh, then updates the NavMeshAgent's destination I am not going to post the code because I don't think the problem resides there, but rather it was something I did in the editor. The character also turns in the correct direction, and starts the walk animation correctly, but it looks like something is blocking its movement, and I can't figure out what that is. The following screenshots will help clarify my situation. Note that the camera is shaking because its position is set to match the character's in Update. The character appears to be colliding with something, which makes it look like the camera is colliding too (note this is not a physics based game in any way). edit here's some more screenshots, showing the person slightly above the ground and their collider (it's the box near their feet). I disabled the collider on the floor so there are no colliders other than the player's. |

0 | How can I scale my UI elements to the lesser screen dimension in Unity 5? I want to create a custom mobile pad for my game. The mobile pad consists of two parts (both inside an ui canvas) The D Pad, which will be anchored to the bottom left side. The button group will be anchored to the bottom right side. I would like to resize the element on different resolutions, so that the element (in my case, the D Pad is an image) Has a size of 20 of the minimum of the width and the height. Has pivot of x 0.5, y 0.5. Having anchor of left bottom, its coordinates are (15 , 15 ) wrt the minimum of the width and the height. What I tried is to use an Aspect Ratio Filter in the D Pad image with ratio 1, but it did not work as intended (the coordinates led the image to an unexpected place). Note I am a n00b to Unity. I don't know whether it is right but my Canvas Scaler scales by Constant Pixel Size These images should illustrate what I want to achieve What should I do to make it work like in the pictures?

0 | Need help with a field of view like collision detector! I ran into a trouble while making a field of view for my character. I figured how to make it work with a Linecast, but what I really need is a cone shaped field, so that the character can detect objects or enemies if they get in that field of vision.

0 | Animation works well on preview but not when hitting play I'm using a simple animation where I want to move an sprite just a little bit bellow its current position, and this works well on preview mode in the Animation tab. But as soon as I hit play, the value I'm trying to animate is not the same as the one in the keyframe, the value is lesser than the one I setted. I don't know what I'm doing wrong...

0 | Adding underwater shadow to 2D top down boat I have a boat hovercraft sprite in my game. It's topdown 2D view, but it's actually a 3D scene, for better lighting and other effects. I want to add a buoyancy effect, so that the hovercraft floats with the waves and has a little margin for going under water, like a real boat. So when idle or when going off a ramp, when landing in the water it will kinda "bounce" a bit under and then back up. But the problem is the water and boat sprites are on top of each other (because it's 2D). See this picture So it can not go underwater, because then the water will be on top. But I still want those edges of the vehicle to be a bit darker as it floats. I already have an effect that changes the Y value to make it float up and down. But now the edges have to become a bit darker to show they go underwater. I kinda have this idea to add a 3D capsule and make it move up and down through the sprite to simulate this So as the boat and the capsule go down with each wave, it could mask the sprite, and the visible part (marked with black lines in the image below) could be made darker. To simulate the "under water" effect. Later I will also add foam and stuff, but the first problem is the underwater part. So how could I mask my sprite inside this capsule, and more importantly, make the "outsides" (so the parts of the sprite not touching the capsule darker? Any help would be greatly appreciated! ) |

The camera is facing in a different direction. Any help would be appreciated. Thnx Matt Follow up from answers I cannot get either solution to work. alejandrodlsp solution doesn't compile (I've added a comment to the answer explaining why). If I do not set offset on Start (aka its always 0), then the camera rotates. The problem is that is at the feet the player and not behind like I wanted. Once I compute offset, then the camera never rotates behind the player. |

0 | How do I position a mesh just outside the camera view? I want to slide in an object into view, coming from the right of the screen. In order to achieve this, I need to position the object next to the camera view, so that it is still not visible, but close enough for a quick slide in.

0 | Jumping onto higher ground Collider issues What's the general solution to the following character animation problem (I'm using Unity)? You have a character with a capsule collider and a jump animation that allows you to jump onto higher ground (such s boxes, etc.). The character shouldn't be able to jump unrealistically high so she goes into a crouched posture while in the air and the collider is scaled accordingly in an animation curve. However when the character jumps onto the box to land, the character animation (and collider) want to extend back to wards the ground but there is not enough space and either collision detection fails and the character falls into the geometry or the collider starts a collision fight with the box and keeps bumping up and down, keeping the character in an airborne state. Please see screenshots to get a better idea... What would be a good way to work around this problem? |

0 | Interpolation on Rigidbody2D not working I'm trying to achieve smooth movement for a ball. I seem to be failing to achieve this and now I've created a sample scene, which shows my setup from the game and the problem exists in that sample scene, as well. I've uploaded the sample project to github https github.com iQew PhysicsTesting (open Assets Scenes SampleScene) Here's a recording of the problem. It's a bit more extreme here than it is in the editor, but it shows the problem even better because of it https imgur.com a ByzwKlg Scenario I have a 2D mobile game (android) using Unity 2019.4.14f1 with URP. The camera does not move and will always have the same settings. The playfield consists of a certain area, which is blocked in by walls, which have a BoxCollider2D on them. The ball is a simple sprite with a CircleCollider2D, RigidBody2D and a Trail Renderer. I have deleted all quality settings except the quot Low quot one, which has VSync Count set to quot Don't Sync quot . In the Awake block of a controller script I set the Application.targetFrameRate to 60. In the Start block I use BallRigidBody2D.AddForce(new Vector2(1f, 10f), ForceMode2D.Impulse) to make the ball move. The RigidBody2D of the Ball has the following settings Body Type Dynamic Material DefaultBall (a Physics2D material with friction 0 bounciness 1) Simulated true Use Auto Mass false Mass 0.025f Linear Drag 0 Angular Drag 0 Gravity Scale 0 Collision Detection Continous Sleeping Mode Start Awake Interpolate Interpolate All other project settings are at default. When I launch the game, the ball starts moving as expected. Most of the time the movement is smooth, but there is stuttering every now and then. I am wondering, if there is a way to make this stuttering go away. The tutorials I found on the internet, which solve this exact problem set the Interpolation mode of the RigidBody2D to quot Interpolate quot , but I did that and there's no change. There are no other scripts interfering with the physics calculation at all. So, I assume this has to do with some kind of project settings? Using a smaller Fixed Timestep does not help, in fact it gets a lot worse, if I use 1 120 for example. Any help would be greatly appreciated! |

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 get which gameobject the mouse is over in Unity? So I'm working on a simple drag n drop based trading card game for my own amusement. There is a card inspector included. What I want to achieve is to change values in the inspector (which has its own Inspector.cs, so I would change the variables in it) based on which card I hover over with my mouse. Each card has its own Card.cs attached from which I want to read the values of the current card. If I try to do this from within the Inspector.cs by something like this Name.text gameobject.GetComponent lt Card gt ().Name , then obviously it won't work, because using gameobject in the current context is not valid. So solution No1 would be to properly reference the gameobject over which the mouse is, which I don't know how to do. When I try to do the same from within Card.cs, I cannot use an event trigger OnPointerEnter and run the code through that, because I have to have a reference to the gameobject that contains that function. ( And I cannot do that in a prefab, only in gameobject already existing in the level.) So could anyone tell me how I could achieve what I want, please? |
0 | How to make a 2D sprite slowly vanish as it crosses a line as if disappearing behind a wall? ...Except there is no wall. Only one of its edges. Here is what I mean. Notice how the lines "sink" into the center square. I've been trying to do something very similar, in Unity. My approach is to detect when the lines come into contact with the center square (hexagon, in my case), and first initiate an animation that decreases the width of the lines, precisely timed via math to last exactly as long as needed. But there's a problem. The animation doesn't play. I've spent the last few hours debugging it, to no avail, and now have finally given up, because the problem is too complex to post here. Too many variables. Are there any better methods of achieving this? My own, even if it had worked, wouldn't have been perfect, because the width would've decreased on both sides (of the line running in the middle of the thick squares or hexagons that are to disappear), giving it a strange, swallowing effect, but I'd be satisfied, since it's just a practice project. So, I'm giving up on this approach. What are easier ways to do this? (Preferably in Unity, but I'll take anything.) Hasty edit Keep in mind that my "lines" are not sprites but line renderers, but I'm looking for ways to work on either. |

0 | When creating a game, what are some architectural desgin concepts I can use to be able to port my game from single to multiplayer? I am a software developer but, I mostly develop games in Unity. I have experience creating single player games as well as multiplayer games. I am at a crossroads where I am in the middle of development of a proof of concept or small demo and all of a sudden I am asked to turn it into a multiplayer game without prior knowledge of this I turn around and say it would add 50 to development time because I basically have to start over from scratch because I didn't necessarily take into account that later down the road they might want to change the experience from single to multiplayer. So with all of that out of the way, are there any different methodologies out there that would make it easier on the developer to port a game from single player to multiplayer? I have thought of a possible way of doing this by just setting the game up as single player, however, making my functions where they are easily able to wrap them using Commands and RPCs. But I find this may or may not help me and is only dependent on what the requirements are. My biggest time killer when it comes to porting these PoC's is typically the UI. Most of the time my requirements are so that the UI will be the same shared UI for all clients and having to update it for each action performed on it and dealing with handling ClientAuthority. (Any tips for dealing with this would be greatly appreciated too) Think of this as something like, making something with Legos in multiplayer and having shared instructions based on the step the user is on. Summary What are different ways that I can design a small demo concept where I can easily port it to multiplayer later on, or make my game where it is "multiplayer friendly" ? Or should I try to stay away from this type of thinking altogether and just develop a single player aspect and just develop a multiplayer aspect, arguments for and against this concept are sought after. |
0 | How can i make my soldier to patrol over the space stationin random? I mean i want to bake all the places in the space station and make the soldier to move automatic around the spaceship to random places. What i did so far is placing the soldier at a start point. Added a camera as child to the soldier. Added a nav mesh agent component to the soldier. Attached a script to the soldier It's not my script. I don't want the soldier for now to chase only to walk randomly around the space station. I didn't change any of the setting on the Nav Mesh Agent component in the inspector and i didn't Should i change anything in the nav mesh agent component and if so what ? How do select or set what areas to bake so the character will know to walk to this areas or if i want to select all the areas ? How do i tell the character when to turn right or left in case there is a wall ? Could be also random to turn left or right. Depending if there is left and right ways or maybe there is also straight way so that's 3 possible ways to move to. clicked the Bake button yet. I didn't write yet the script. using UnityEngine using System.Collections public class SoldiersPatrol MonoBehaviour |
0 | Relative vertical alignment of 3 Texts on Canvas This is a menu that appears if I press Enter on the RE4 inventory if an item is selected. I have drawn a thin red rectangle around it And here is a video that shows some of the menu's effects. I am familiar with a simple text canvas. I understand that I need to make each line a separate "Text" object so that I can scroll up and down through them. Here is what I have so far The problem that I'm facing now is that the Canvas will be scaled at runtime. I don't work with fixed values. This is a problem since I don't see how I could easily make it so that each TextLine object fills 33,3 of the canvas. Am I right to assume that I can only solve this by making a scripts that holds a reference to each TextLine object and which then calculates their position when the scale of Canvas is known? Or is there any easier solution? Thank you! |

0 | "Overloading" GameObject? I would like to show weapons and health items in an inventory grid. The item can be rotated in the grid, and it occupies a certain region in the grid. Currently I store this information (where the item is located, if it is rotated, etc.) in an additional array. However, this is not elegant and error prone. I would therefore like to ask if it is possible to somehow store this additional information directly in the weapon or health GameObject. Ideally I would like to be able to do something like this Pistol.GridProps.Rotation 90 Pistol.GridProps.Row 5 Pistol.GridProps.Col 3 Is it possible to add something like "GridProps" to all my game objects?

0 | How do you rotate RigidBody2D along a given access using velocity and not transform? I am trying to rotate my player along the centre of the world in Unity3D. All the tutorials and references I have looked through till now have left me to this working code void MoveAlongCurve(bool moveClockwise) if (!moveClockwise) timeCounter moveSpeed Time.fixedDeltaTime else timeCounter moveSpeed Time.fixedDeltaTime float x Mathf.Cos (timeCounter) float y Mathf.Sin (timeCounter) transform.position new Vector3 (distFromCentre x, distFromCentre y,0) Also this seems to work fine as well transform.RotateAround (Vector3.zero,new Vector3(0,0,1),speed) Now my question is how do i move my player using velocity? I was forced to keep my body as 'kinematic rigidbody2D' however I want my player to be a 'dynamic rigidbody2D'. My reason for this is several 1. Movement via velocity makes it independent of the timeCounter. 2. Dynamic Bodies enable collisionDetection. Hence it is basically a requirement for my game. Thank you so much for taking the time to read this! Any suggestions or nudges in the right direction would be greatly appreciated and if you find anything wrong in my code or approach please comment! |

0 | How can I make the cursor avoid something completely? I wrote some code for a UI button that causes the mouse to avoid it. I realize this is kind of a weird thing to do in a game design wise, but this is a really weird game. I need a button that is not only unclickable, but also unhoverable. I got it mostly working, but I cannot seem to change the position before the mouse is drawn, probably because mouse movement is handled by the OS, unless there is a problem with my code that I missed. As a result, pushing the mouse against the button boundaries results in a stutter. The mouse briefly appears over the button before I can move it, so it is still possible to click the button. A demonstration of the button avoidance and stutter https youtu.be 7tgIrJ vMDg DllImport("user32.dll") public static extern bool SetCursorPos(int X, int Y) DllImport("user32.dll") public static extern bool GetCursorPos(out Point pos) ... void Update () var mousePos Input.mousePosition if (Application.isFocused amp amp isOver) Get the current mouse position from OS so we can change it Point cursorPos GetCursorPos(out cursorPos) if (oldMousePos.x gt xMin amp amp oldMousePos.x lt xMax) Coming from above or below. Figure out which one and move mouse accordingly if (oldMousePos.y gt uiPos.y) cursorPos.y (int)(rt.rect.height 2 (mousePos.y uiPos.y)) else cursorPos.y (int)(rt.rect.height 2 (uiPos.y mousePos.y)) else Coming from either left or right. if (oldMousePos.x lt uiPos.x) cursorPos.x (int)(rt.rect.width 2 (uiPos.x mousePos.x)) else cursorPos.x (int)(rt.rect.width 2 (mousePos.x uiPos.x)) Give new coordinates to OS to update mouse position SetCursorPos(cursorPos.x, cursorPos.y) else track the old position to know what direction they moved their mouse from so we can put it back oldMousePos mousePos I tried using the Cursor API to force it to software mode thinking that might fix it, but it still stutters, and I would prefer to use the default cursor anyway, and hardware mode if possible. Is there any way to work around this or remove the stutter? |

0 | Some meshes are visible in game view while others are not I have a FPS character in unity. The FPS character is divided into a few different pieces (upper arm, lower arm, hand, fingers, etc). I exported it from blender, so I'm using the camera that got converted from the blender camera. For some reason, the mesh is not showing up in the game view camera vision. I did a little bit of testing and found out that If I move the camera away, the mesh shows up, so the mesh isn't invisible or anything I put a version of the character that I imported from blender earlier as a test(different rest pose and less animations attached to it) in the same location as the FPS character, and attached the same animator to it. When I did that, you can see the earlier version but not the newest one The same thing happens even if I change the camera The camera has a field of view of about 67, and a focal length of 18. Near is set to the lowest value possible. Both characters are visible in scene view, just not in game view. |

0 | How is the density of a collider determined? I read here that, once determining the density of a Buoyancy Effector, "Colliders with a higher density sink, those with a lower density float, and those with the same density appear suspended in the fluid." However, I did not find a density field in my CircleCollider2D. What I found is that If I increase the mass of the attached RigidBody2D, then the body sinks into the fluid since apparently its density increases. If I keep the mass but decrease the size of of the circle collider, then again the body sinks into the fluid indicating that its density increases. So my conjecture is that the density is calculated by the mass of the rigid body, divided by the volume of the collider. But I did not find the formula in the Unity manual. Is this correct? |

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?

0 | Trying to find a solution for instant knockback in multiplayer game I'm making a server authoritative fast paced multiplayer game. I'm trying to implement wack hammers, they are a melee weapon that knocks close players, in other words, that sets their velocity to inverse of their mass to the direction aimed at the force of the hit. Even if the enemy player is only seen getting knocked after the client input gets processed on the server and after the enemy's position and velocity get sent back, I want to make it seem like your action appeared instantly. I've tried one thing when you knock a player, that player gets predicted for a short amount of time instead of being interpolated. That way, players appears to have been knocked out instantly, but there's an issue with that. When should I stop predicting? And how? When you think about it, the prediction is done on your own client time. The positions and velocities of other players are a few millisec old, so when you try to interpolate between your local quot futur quot predicted player position to the quot old quot server player position, you essentially move the other players back in time, and it looks real bad. I'm not quite sure what to try to hide this issue. I can't possibly predict the enemy player's position forward in time, its movement can get too chaotic. I've already watched the GDC talk from Overwatch's and Rocket League's netcode a million time, I'm not sure if they can help me with my issue. Edit I still haven t found the best solution yet but there s some useful information over at https forums.unrealengine.com development discussion c gameplay programming 1455487 responsive knock back in multiplayer game |
