0 | unity problem in limiting rotation of object? I am trying to make a game with unity. In this game, player uses mouse to rotate a container or box around x and z (rotate to left and right and also toward the camera and opposite). I used below code to control movement and limit it. float zRot transform.eulerAngles.z float xRot transform.eulerAngles.x float yRot transform.eulerAngles.y Debug.Log ( "xDir " xRot.ToString() " yDir " yRot.ToString() " zDir " zRot.ToString() ) if ((xRot gt 330 xRot lt 30) amp amp (zRot gt 330 zRot lt 30)) transform.Rotate (Input.GetAxis ("Mouse Y"), 0, Input.GetAxis ("Mouse X")) else Debug.Log(xRot.ToString() " " zRot.ToString ()) transform.Rotate ( transform.rotation.x , transform.rotation.y, transform.rotation.z ) The contatiner rotate 60 degrees in x and z and when it gets to the limits it stops, which is what I want. However when I rotate in both direction to the near the limits (330 or 30), the contatiner becomes out of control and it rotates freely and constantly. It's like the contatiner has passed the limits. The questions are Did I used a good approach to limit the rotation and how to stop the object completely when it get to the limit of rotation? When and why the object becomes out of control exactly? |
0 | Unity3D playing sound when Player collides with an object with a specific tag I using Unity 2019.2.14f1 to create a simple 3D game. In that game, I want to play a sound anytime my Player collides with a gameObject with a specific tag. The MainCamera has an Audio Listener and I am using Cinemachine Free Look, that is following my avatar, inside the ThridPersonController (I am using the one that comes on Standard Assets but I have hidden Ethan and added my own character avatar). The gameObject with the tag that I want to destroy have an Audio Source In order to make the sound playing on the collision, I started by creating an empty gameObject to serve as the AudioManager, and added a new component (C script) to it using UnityEngine.Audio using System using UnityEngine public class AudioManager MonoBehaviour public Sound sounds Start is called before the first frame update void Awake() foreach (Sound s in sounds) s.source gameObject.AddComponent lt AudioSource gt () s.source.clip s.clip s.source.volume s.volume s.source.pitch s.pitch Update is called once per frame public void Play (string name) Sound s Array.Find(sounds, sound gt sound.name name) s.source.Play() And created the script Sound.cs using UnityEngine.Audio using UnityEngine System.Serializable public class Sound public string name public AudioClip clip Range(0f, 1f) public float volume Range(.1f, 3f) public float pitch HideInInspector public AudioSource source After that, in the Unity UI, I went to the Inspector in the gameObject AudioManager, and added a new element in the script that I named CatchingPresent. On the Third Person Character script, in order to destroy a gameObject (with a specific tag) when colliding with it, I have added the following void OnCollisionEnter(Collision other) if (other.gameObject.CompareTag("Present")) Destroy(other.gameObject) count count 1 SetCountText() It is working properly as that specific object is disappearing on collision. Now, in order to play the sound "CatchingPresent" anytime the Player collides with the object with the tag, in this case, Present, I have tried adding the following to the if in the OnCollisionEnter FindObjectOfType lt AudioManager gt ().Play("CatchingPresent") But I get the error The type or namespace name 'AudioManager' could not be found (are you missing a using directive or an assembly reference?) AudioManager.instance.Play("CatchingPresent") But I get the error The name 'AudioManager' does not exist in the current context As all the compiler errors need to be fixed before entering the Playmode, any guidance on how to make the sound playing after a collision between the player and the gameObject with the tag Present is appreciated. |

0 | How to use a whole new set of assets (reskinning) I need to be able to load my game with a different set of assets, basically reskinning it. I knew beforehand that I would need a way to do that in the future so right now i'm accessing my assets via a ScriptableObject that I call an "Accessor". Basically the accessor only hold references to the assets and when I want to get, for example, the sprite for my cards I make a call that looks like that Sprite cardSprite Accessors.Instance.GetCardFrame() Solution seem simple, I add a layer above the accessors that allow it to choose between differents sets of references. The problem is that right now I only use the accessors for dynamically generated gameobject ( When I instantiate a card for exemple ). How could I do that with, let's say, UI in the editor ? It will be nearly impossible to work on the UI if I can't see it due to the sprite not being loaded in editor mode. |
0 | Will Unity skills be transferable? I'm currently learning Unity and working my way through a video game maths primer text book. My goal is to create a racing game for WebGL (using Three.js and maybe Physic.js). I'm well aware that the Unity program shields you from a lot of what's going on and a lot of the grunt work attached to developing even a simple video game, but if I power through a bunch of Unity tutorials, will a lot of the skills I learn translate over to other frameworks engines? I'm pretty proficient at level design with WebGL, and I'm a good 3D modeller. My weaknesses are definitely AI and Physics. While I am rapidly shoring up my math, and while Physics is undeniably interesting there's only so many hours in the day and there's a wealth of engines out there to take care of this sort of thing. AI does appeal to me a lot more, and is a lot more necessary. AI changes drastically from game to game, is tweaked heavily during development, and the physics is a lot more constant. Will leaning AI concepts in Unity allow me to transfer this knowledge pretty much anywhere? Or will I just be paddling up Unity creek with these skills? |
0 | Unintended window opening when pressing Unity's "Submit" button I've been working on a top down 2D game for a while now, and yesterday I found a strange bug that I just can't explain to myself whatsoever. I have a loot window for looting enemies, as well as a character panel to equip gear see stats. I realized that after I open and close a loot window, if I press the space button (used for attacking, not for opening any windows) while holding A LeftArrow or W UpArrow it opens the character panel. Once this happens, I can press space to open close the character panel. Went to the character panels OpenClose() function (all it does is set the canvas group alpha to 0 and block raycast to false and vice versa) which is being called unintentionally, put a debug.log inside to verify if it really was being called, and yes, it is. I look up all references to see where I used it, but I only use it in a single place in the project that is behind an if statement looking for they keycode C (NOT space). I added a debug.log for the Input.inputstring to see if somehow a magic C button press is ending up in that function, but no. If I press C to open the window, the debug log pops up, if I press space, the inputstring appears to be empty, so the if statement to get to the only place in the code referencing that function cannot be met. Removed the space button from my Player entirely, the behaviour still persists. Added another debug.log with stackTrace.GetFrame(1).GetMethod().Name to show who is actually running this function, but it turns out that if I run it and press C, it says it's being opened by the update function in the UIManager (as expected). If I run it the strange, unintended way, it says it is being run by the EventSystems Invoke function. Coupled with the fact that the behaviour persists despite the space button being removed from the player, I realized that it's Unity's built in "Submit" button being pressed. Strange behaviour It appears to call the submit function on the OpenClose button for the character panel, but only under the circumstance that I closed a loot window and haven't clicked the mouse anywhere yet afterwards. If I deactivate the button that holds the character panels OpenClose function, the behaviour stops. The button shouldn't be pressed though, because it is on a canvas group with alpha 0 block raycast false, just like all the other buttons with the identical function that work fine. The loot window has no idea about the character panel either, and all the windows are properly wired to their own OpenClose function. Upon further inspection, the window only starts showing up if, after closing a loot window, i press A LeftArrow Space or W UpArrow Space. This is getting more and more confusing for me. So basically my issue is how do I figure out why this function is being called? It feels as if closing the loot window somehow "caches" the OpenClose button for the character panel onto the submit button, but only until I click elsewhere on the screen. Did you guys have any experience with a similar situation? Could you share some pointers on how to debug this? What is the "submit" button usually used for, and what would make it only work in combination with the left top directional buttons? I've spent about 4 hours on this now and don't know how to get any further. |
0 | How can I increase the speed and frequency of a spawn? I'm using the official Unity tutorial for the Space Shooter game, and I'm at the part where the ability to spawn a set amount of hazards in a wave at a certain delay is introduced. I want to make it so that at the end of a certain level, the speed of the hazards, and the amount of hazards both increase. I'm pretty sure that can be handled in the game controller, but I don't know the commands I would be needing to use to make that happen. This is the existing code public class GameController MonoBehaviour public GameObject hazard public Vector3 spawnValues public int hazardCount public float spawnWait public float startWait public float waveWait void Start () StartCoroutine (SpawnWaves()) IEnumerator SpawnWaves () yield return new WaitForSeconds (startWait) while (true) for (int i 0 i lt hazardCount i ) Vector3 spawnPosition new Vector3 (Random.Range ( spawnValues.x, spawnValues.x), spawnValues.y, spawnValues.z) Quaternion spawnRotation Quaternion.identity Instantiate (hazard, spawnPosition, spawnRotation) yield return new WaitForSeconds (spawnWait) yield return new WaitForSeconds(waveWait) What commands would I need to use to increase the amount of hazards that spawn at the end of each round? And likewise, how could I change the Hazard's script so that it will increase in speed by a certain factor at the end of each round? Is there a way I can reference the hazard's script in this script, by any chance? |

That means that the user must not collide with other players, but must not pass walls, trees, and must take care about terrain height levels (I mean, I can't put it as kinematic and remove the collider because the Vector3.MoveTowards which moves the player will ignore the height dimension and will pass the mountains, etc) My was thinking about tagging the players and in some way try to skip the collider between them.

0 | How can I update a sprite sheet without affecting the sprites already being used? Every time I overwrite my sprite sheet with additional or updated sprites, I have to reattach the textures to all of my Animations and Sprite Renderers. How can I update a sprite sheet without affecting the sprites on that sheet which are already being used? During the development of even a small game, hundreds of textures are being used. And new textures are being added and updated every day. This results in many hours spent reattaching textures which could otherwise be used being productive. What strategy can I use to prevent this? This is an example of what I mean I have a sprite sheet with 40 textures. All of its sprites are attached to their relative GameObjects. I decide I want to change the color of one of my sprites' hat. I go into gimp and load the sprite sheet. I change the color of the hat. I overwrite the old sprite sheet. Back in Unity, all of the textures are no longer attached to their respective GameObjects. I go in and splice the sprite sheet again and manually reattach all of the textures. Then I decide I like the old hat better. I go back into gimp, change the sprite sheet, and am then forced to reattach all of the textures...again. There has to be a better way! (Also would like to be capable off adding new sprites in addition to editing old ones.) |

0 | How to move object on local space not object space in unity I am watching this (game dev, space parenting amp rotation) Sebastian Lague video and found that there are three spaces actually (not two) and these are world space, local space and object space. World space The static space (0,0,0) Object space related to the object space Local Space related to the parent of the object I am amazed that i didn't find the distinction between these two spaces(local and object) on official unity forms but actually it exists. My question is that why there is no Space.Local? I found that there are Space. Self and Space.World. Space.Self is refer to object space. I can move my object to object space using this void Update () transform.Translate(new Vector3(0,0,1) Time.deltaTime 2,Space.Self) And i can move my object to world space using this void Update () transform.Translate(new Vector3(0,0,1) Time.deltaTime 2,Space.World) but there is no support for local space that i could move the object to local space (means move the object related to its parent object). There is a fair distinction between Local and Object space but unity didn't consider it i guess or i am wrong. |
0 | Going up and down stairs by Unity3d's NavMesh Purpose I want to create a navigation mesh that is optimized for going up and down stairs and stopping. Question I'm making a nav mesh to make a character go up and down stairs. I'm making a nav mesh that makes a character go up and down stairs, but when the character stops in the middle of a step, his foot floats or his foot gets stuck in the stairs. I'm having a hard time creating a good path for the nav mesh. I'm wondering if you have any knowledge on how to bake a nav mesh for ascending and descending stairs. Please let me know what you know about baking navmeshes for stair climbing and descending, and what pages or ideas I should refer to when implementing stair climbing. Please let me know what you know about baking a nav mesh for stair climbing. Preparation Create the stairs and the ground in Probuilder so that the nav mesh can be baked. Case 1 Bake the nav mesh of the stairs. Test result. When ascending and descending the stairs, my feet sink into the ground. Every time I ascend or descend a flight of stairs, the surrounding scenery wobbles up and down. Case 2 Make a board to accompany the stairs. Bake the nav mesh with the stairs hidden and the slope displayed. Test result. When ascending and descending the stairs, the feet do not sink in. But when I stop at the step, my foot floats away. The scenery does not wobble because you are running on a board. Case 3 I made a board to accompany the stairs. I want to make the nav mesh of the step part flat. I want to make the nav mesh of the step part flat, so I'll edit the step part with the Probuilder function. Instead of a straight slope, lower the knot to create a slope and bake it. Test result. There is not much change in the shape of the nav mesh from Case 2. The phenomenon that the foot lifts off the ground when stopping at the step was not improved. The scenery is not wobbly because you are running on a board. Navigation mesh we want to achieve Development environment Unity2019.4.9f1 Package used ProBuilder4.2.3 |

0 | Send a Push Notification from a device to another device (Unity, Firebase) I have setup Firebase authentication in my game for Android. I need to implement a feature in my Android game, where a user can challenge another player. I need to implement it this way The user is shown the list of all users registered on Firebase on the Game. To any user, he can tap on a button for respective user to send a challenge. When, he taps, a push notification is to be recieved by that user. When he taps on the notification, he is redirected to a specific part of the game. Maybe a specifc scene for now and he is shown there the Challenger's name. I have explored the Firebase documentation, but it does not provide information for client client push notifications. Maybe there are other options available like GameSparks and OneSignal. But I don't know if there is a requirement of own Server for implementing it. |

0 | Discarding triangles in Unity I have about 2 years of experience in computer gaming development and I just started writing my own shaders to help me utilize performance. I have this problem that I'm trying to work around but after several tries nothing seems to work. Basically, I have a plane that's made of 16641 vertices thats 32768 triangles and I know that is pretty much. The plain has a texture on it with some colors. Now, what I am trying to do is placing units on that plane. Where they stand, the vertex under them will have a certain color but all other vertexes on the plain will have the color white. The idea is to discard and don't draw vertexes that aren't white. Now in the shader, I tried two things. 1 In the vertex input I check if the vertex, called o, had the o.color.b value ! 0. If so it was given the alpha value of 0 and would not be seen when rendering. 2 In the vertex output, I checked the same thing ( if(i.color.b ! 0) discard ) and discarded the fragment so it would not be rendered. That way I thought Unity should not count these triangles and thus wouldn't waste performance. Now when I run my game and open the stats, with the plane active I have 85.8k triangles and only 28 draw calls. With the plane un active I have 20.2k triangles and 26 draw calls (Note there are some units, interface, skies etc around that counts up to 26 draw calls, thus the plane is just 2 draw calls). I thought this solution would be clever to save draw calls (developing for mobile games) by treating this plane and the colors under the units as one instead of making them all a separate gameobject. Turns out, I'm way over budget on the triangles. Does anyone know if this is possible and if so, give a good answer or explenation? Here is the following shader. Shader "Custom Ottar VertexBasic" Properties MainTex ("Particle Texture", 2D) "white" Transparency("Transparency", Range(0,1)) 1 SubShader Tags "Queue" "Transparent" Blend SrcAlpha OneMinusSrcAlpha AlphaTest Greater .01 ColorMask RGB Lighting Off ZWrite Off Fog Color (0,0,0,0) Pass CGPROGRAM pragma vertex vert pragma fragment frag pragma multi compile builtin pragma fragmentoption ARB precision hint fastest include "UnityCG.cginc" uniform float4 MainTex ST float Transparency VertexInput struct vI float4 vertex POSITION float4 texcoord TEXCOORD0 float4 color COLOR uniform sampler2D MainTex VertexOutput struct vO float4 pos SV POSITION float2 uv float4 color vO vert (vI v) vO o o.pos mul (UNITY MATRIX MVP, v.vertex) o.uv TRANSFORM TEX(v.texcoord, MainTex) float4 viewPos mul(UNITY MATRIX MV, v.vertex) o.color float4(v.color.rgb, v.color.a 1) if(o.color.b ! 0) o.color.a 0 else o.color.a 1 return o float4 frag (vO i) COLOR if(i.color.b ! 0) discard else half4 texcol tex2D( MainTex, i.uv ) return texcol i.color Transparency ENDCG Fallback "Particles Alpha Blended" |
0 | In Unity how can I know which direction is the screen auto rotated? From the Screen.orientation description I get If the value is set to ScreenOrientation.AutoRotation then the screen will select ... automatically as the device orientation changes. This seems to imply that if the screen does auto rotate, then Screen.orientation has been set to ScreenOrientation.AutoRotation. If that's so, how can I know in which direction it has been auto rotated? Disabling the auto rotation doesn't count (obviously), and I need to distinguish between LandscapeLeft and LandscapeRight, so checking height and width doesn't work either. This should be cross platform, without including any kind of non C plugin. (the answer, given this documentation, seems to be "you can't", but maybe I'm missing something) |
0 | Player going out of boundaries So, I been following up the Space shooter tutorial on Unity, I had an issue where the project was acting up with an alpha version, so I was able to get a version that worked on a old release and applied all the new things I developed But suddenly, my ship is acting up when getting closer to the boundary of its movement This is the player movement code public class playerMovement MonoBehaviour public float speed 0.0f public float tilt public Boundary boundary void FixedUpdate () float moveHorizontal Input.GetAxis("Horizontal") float moveVertical Input.GetAxis("Vertical") var movement new Vector3(moveHorizontal, 0.0f, moveVertical) var rigidBody GetComponent lt Rigidbody gt () rigidBody.velocity movement speed rigidBody.position new Vector3 ( Mathf.Clamp(rigidBody.position.x, boundary.xMin, boundary.xMax), 0.0f, Mathf.Clamp(rigidBody.position.z, boundary.zMin, boundary.zMax) ) rigidBody.rotation Quaternion.Euler(0.0f, 0.0f, rigidBody.velocity.x tilt) System.Serializable public class Boundary public float xMin, xMax, zMin, zMax And this is the player boundary properties It used to work previously moving forward to the alpha, now I'm working on 2019.2.0f1, but since working on the alpha this is the behaviour I'm having As you can see, getting closer to the player boundary, takes the player out of the play area, and I can't determine why this might be happening. I already tried removing the Math.Clamp, as I though there migth be bug with the function in this version, but even without it, the problem is present. |
0 | Frequent stuttering, high FPS spikes with VSync option turned on in Unity standalone build I'm experiencing an issue using Unity 4.3.2 and standalone builds. If I turn on VSync in the project's Quality settings, running the game at the native monitor resolution, I'll frequently get high framerate spikes (over 100FPS), and a strong stutter for a few frames, and then it drops back down to 60FPS and runs normally. If I run the game at a lower resolution (800x600 for example), the framerate stays at around 500FPS and the stuttering is consistent. However, if I turn off VSync in the Quality settings, and force it on in the Nvidia Control Panel, I don't experience any stuttering or framerate spikes, nor when I turn off VSync completely (but lots of screen tearing, which is very ugly and distracting). Can anyone explain this behavior? Is there anything that can be done to circumvent it? I'd imagine other Unity developers have used the built in Unity VSync with success before (or maybe not?!) so I'm hoping I'm just doing something wrong on my end. |

0 | Unity how to change runtime code for different platforms? In Unity, how can I programmatically control what source code is compiled? I have a script with various BuildPipeline.BuildPlayer calls, allowing me to build all versions of my game. However, I'm using the AVPro Video asset to play video, and it doesn't support 32bit Mac. As such, I need to fall back other video playing code on 32bit Mac. There's no preprocessor directive to differentiate 32bit OSX (like you can do for other platforms https docs.unity3d.com Manual PlatformDependentCompilation.html ). However, since I'm building each version in sequence, it seems like I should be able to set some state so that during compilation, the right code is used. I tried this VersionHandler.onMac32 true BuildPipeline.BuildPlayer(levels, path, BuildTarget.StandaloneOSXIntel, BuildOptions.None) VersionHandler.onMac32 false And then checking that static variable in game. However, that static is "never set", presumably because the the state of the variable during compilation doesn't affect the value at runtime. Is there any other way I can "get at" the compiled code and set a flag for certain builds? As a fallback, I can manually swap code in every time I build for OSX 32 bit, but I'd prefer not to do that. |

0 | Why does my AI Enemy slide towards its target when it is supposed to be idle? So using Unity standard assets to get a stage rolling, Ive built a simple terrain and used FPSController as the player and AI ThirdPersonController (Ethan) as the enamy.

Ive tried adding friction materials to the terrain and the collider on Ethan but he still slides. Help thanks |
0 | Select a button without calling click i have a grid layout group containing buttons. My game must be playable with a joystick and so I have to navigate the buttons using horizontal vertical input. My problem right now is when the layout group first becomes visible. Once I click on a button (with my mouse), it becomes "selected" and I can navigate through the layout group with my keyboard and 'click' with spacebar. This functionality is all fine, except for the need to click the button with a mouse to set the first selection. I've tried both of the following void buttonClicked() Debug.Log("clicked") void Start () this button is actually instantiated from a prefab, not shown here Button btn inventorySlot.button btn.onClick.AddListener(buttonClicked) attempt 1 btn.Select() attempt 2 eventSystem.SetSelectedGameObject( btn.gameObject, new BaseEventData(eventSystem) ) both these commands do select the button, but they also inadvertently call the onClick, and the button is clearly being clicked because it changes color (I have configured this through button opts in the inspector). My question is how can I "select" the button without clicking it? I perhaps should also note, I am populating the layout group with buttons at runtime. Each button is intantiated from a prefab in Start() (not showing that here). I only add the event listeners and try to select the button after it's already added to actual game objects in my scene. |

0 | How to set keys for emission on off for a prefab? I am making a prototype for a Mario game and am having difficulty completing a canned animation for a prefab. There is an item box asset that has 3 materials and an "ItemGet" animation. One of these materials has an active emission property that is supposed to turn off during a specific frame of the "ItemGet" animation. These boxes will have an "Active" and "Inactive" state. While "Active", the item box just bobs up and down and IF Mario hits the trigger, the "ItemGet" animation plays (and the player gets a unique item). The box then becomes "Inactive". While "Inactive", no animations play, the emission effect is gone and the trigger cannot be reactivated. Challenges finding the correct property to set a keyframe for in the Animations panel. Making sure Active versions of the prefab remain Active after any ItemBox becomes Inactive and that all materials don't change when GetItem plays. Ideas Instead of keying the emission on off property (assuming that exists and does what I think it does trouble finding it), swap the materials. ( . . . ), swap the mesh. Can somebody please help me find a viable way to finish this animation that fits this object's intended use case? |

0 | Unity C Using Linecast with collider bounds I'm trying to to detect when two 3D objects overlap each other 'visually' without actually touching. For example, if I have two spheres in a scene that are 1 meter apart and I rotate my camera around the objects so that one sphere is blocked by the sphere in front of it, I want to detect when this occurs. After many searches in this forum, I patched together the solution below. However, it only partially works it only detects overlap when the center of the occluded object is reached (i.e., "bounds.center"). I read that there is a way to use the bounds in this scenario so that it samples multiple rays from around the object.

0 | Unity3D) Is there a way not to draw line renderer if vertex pos is zero? I make a curved line with line renderer. and a sphere move along it. i want to draw a line only behind the sphere. so i do something like this. lr.positionCount 256 while (delta lt time) lr.SetPosition(i , curPos) yield return new WaitForFixedUpdate() and the problem is, because of i set the size of Positions 256, if time is short, there are zero vectors in position. so line renderer draw meaningless line. is there a way to set PositionCount dynamically like List? or any good way to not draw if positions are zero? |
0 | How to make Scriptable Objects derive from other Gameobejcts? I encountered a problem where I want to make a Scriptable Object that derives from another class, but C does not support multiple inheritance. Further, I do not think it would not make sense to make interfaces for this example. There is a lot of duplicate code within methods that only an abstract class could contain implementations of. Basically, I want an abstract class that models "anything that can take a turn." I call it a TurnTakeable. But I also want the TurnTakeable to be split into friend and foe derived types, as the two are slightly different. Yet they mostly have the same behavior. Is there a workaround, or do I have to make an interface? ( |

0 | How can I attract repel the mouse cursor from particular UI controls? This question came from some of my students. I wanted to share it here so others can find amp improve on the solutions we've found so far. In particular, my answer below doesn't behave as well as I'd like in windowed editor mode UI buttons no longer respond to hovering the cursor. I welcome alternative answers that solve this more completely. We're making a visual novel game using the Fungus asset for Unity. We want to add a twist where some dialogue options are easier or harder to press, because they attract or repulse your mouse cursor. Unfortunately, we haven't been able to identify a cross platform way to manipulate the mouse's position, nor a way to create a "Fake" mouse cursor image that can still interact with Fungus's UI buttons. How can we pull this off? |

0 | Gradient Input in Game view I want to develop a little tool to help visualize fireworks before using them in a show in Unity where the user can set several parameters and gets a preview of the firework effect in a preview window. To allow the user to customize color over time like I can currently statically do in the visual effects graph, I wanted to add a Gradient input field to my UI. After fiddling around with manually trying to make things work, I stumbled upon the new UIElements UI Toolkit and following this Medium post was able to render a simple text UI in a Panel Renderer. However the Gradient Field I added won't show up (which is quite reasonable because in the UI Builder it said something about quot Editor only quot ). Just to make sure, the box on the left is what I mean I was strolling around in the Asset Store for a while but couldn't find anything like what I was looking for (just shaders and stuff to apply a gradient to UI elements amongst other things). Other searches led to tutorials on how to completely custom build a single color selection tool which both seemed like a larger effort and didn't allow creating a full gradient. The question is Is there some sort of library, package or tool I could use to add an input like that to my quot game quot ? Or am I taking a completely wrong approach with this? |

0 | GameObjects deleted before scene loads I am trying to persist objects on scene loading, but the objects always get deleted when the scene does load. LevelManager.CS public void LoadLevel(string name) if (name "Main") SceneManager.LoadSceneAsync(name) GameManager.LoadState() else GameManager.SaveState() SceneManager.LoadScene(name) Debug.Log("the scene is " name) I placed the LoadScene method ontop in the hopes it would complete loading the scene before moving onto the next method call. In the next method call, I restore objects to their state. GameManager.CS public static void LoadState() ES3.Load lt Dictionary lt Vector2, Building gt gt ("Buildings") foreach(Vector2 v2 in buildingPositions.Keys) Building b buildingPositions v2 if(b.GetType() typeof(Farm)) newFarm Instantiate(farmPrefab) as Farm Debug.Log("Build " newFarm) newFarm.transform.position v2 Debug.Log(newFarm.transform.position) newFarm.level b.level newFarm.name b.name newFarm.levelText newFarm.GetComponentInChildren lt Text gt () CheckTheCall() What actually happens is when the scene is changed, the LoadState code is run at the same time, which then causes my object to be deleted after the scene has finished loading, because its created before the scene changes. The third last line "newFarm.name b.name" gives me an error that newFarm was destroyed. The last line "CheckTheCall()" calls newFarm (which I declare at the top of the script to ensure scope wasn't the issue) and that shows newFarm exists as a farm. THEN after all this, the scene changes, so my instantiated object is deleted. I'm so confused I tried with just SceneManager.LoadScene(name) but the result is still the same. It's like the entire function completes and then the scene loads. Any ideas on how to get around this one? I need the objects to spawn back into the main scene in the same state they were. |

This is working. I still wonder why the unity docs example didn't work but this is working and I don't need the editor script.

0 | Unity 2D Cinemachine weird behavior for non rectangular confiner I have been trying to emulate a sort of Megaman X4 way of following the player around platforming levels, where the camera is confined to certain boundaries of such levels. However, all the tutorials and guides out there only show rectangular or square shaped confiners for the virtual cameras, and not odd shapes like an L shaped confiner, when using a weirdly shaped confiner the camera just tends to snap from one position to another and the game ends up feeling bad when that happens. I have tried solving this problem by using dolly tracks, which work nicely... But I end up having tons of virtual cameras to change to on sections that are weirdly shaped since the camera ends up also suddenly snapping on to weird positions on sharp turns and it also tends to get way off track, even when the settings of the virtual camera are configured to have very little damping and if there's no damping the camera just stutters all the time. Is there a way to have this kind of behavior to confine a virtual camera to oddly shaped level boundaries? |

0 | Why does my Unity Android game get a small amount of lag when not being touched for some time? I have made a 3d version of space invaders. I made all the assets myself in Blender. I feel that it's a very basic game and my Galaxy Note 3 test device should handle it no problem. (Although it's a few years old now so perhaps some kind of shader issue or something that my phone not updated enough for ?) There are 55 enemies all with one mesh each. There's the flying saucer model and the player model. Then there's a plane for a background, and 4 defensive meshes (although I've tested without these and the result is the same). Basically, it all runs superbly (I have turned down much of the lighting and graphics quality etc, but have left basic shadows in). However I notice that if the player just lets the phone sit there in game without touching it, there is very slight (but noticeable) frame lag. All the enemies have a very short animation which moves its arms a small amount. I could post the code but its massively unorganized and really quite an embarrassment (HAHA!). Also I'm not sure what parts are relevant so it would be a huge post. Is there any known issues that can cause the lag only when not being touched? As I feel like some of my old projects might have had this happening too but they've been deleted now unfortunately so I can't really dabble with it. It works smooth as silk in the Unity Editor Android 'emulator' and as I say, if I actually play the game on my phone it's smooth too. |
0 | Why is there a discrepancy between these two transform.up vectors? I was trying to implement a feature which required transform.up, the result didn't match the green axis gizmo displayed in the editor so I assumed it was being put off by the rotation of the object despite expecting the gizmo to adapt to that. I then modified the prefab such that everything was now child to an empty object and the secondary objects were child to that instead of the rotating model, and wrote a script that simply copies the transform so that it tracks. This still didn't show the values expected from what the gizmo in the editor showed. I then did a Debug.LogError in the track script and this time the result was as expected. Why is transform.up showing the value expected from the local y axis gizmo but when passing a reference to the original script and checking tracked.transform.up gives off results? To reproduce in a simpler environment I set up a simple test scene. Simple default cube with the hierarchy structure shown in the screenshot. The transform values are as follows parent zeroed x 0, y 90, z 0 for cube x 0, y 90, z 90 for TrackPoint Scripts are as follows test.cs attached to trackpoint private void Update() Debug.LogError(transform.up) Track.cs attached to tracker public Transform transformToTrack private void Update() transform.position transformToTrack.position transform.rotation transformToTrack.rotation Debug.LogError(transform.up) byref.cs attached to cube public GameObject refObj private void Update() Debug.LogError(refObj.transform.up) When run, if you clear the console then click pause you'll see that one of them differs from the others. I don't understand why. My project and this sample scene differ in which it is that is giving unexpected results but the results are inconsistent with what I would expect. But wouldn't they all give the same result? |
0 | World space coords for 2d images How can I make an 2d image using World space coords with a shape? Like a circle instead of a quad.In 3d you can modify the vertices but if I want a smooth circle there will be too much vertices. What I want to achieve is something like a cirle mask that will be move over the global texture at runtime. So has anyone done something similar? I've tried combining some shaders with two uv's one for world space and one for alpha uv mesh but it gives some weird artifacts. This is the how the shader looks on the right Shader "Unlit WorldspaceTiling" Properties MainTex ("Texture", 2D) "white" SubShader Tags "Queue" "Transparent" "IgnoreProjector" "True" "RenderType" "Transparent" LOD 100 ZWrite Off Blend SrcAlpha OneMinusSrcAlpha Cull Off Lighting Off ZWrite Off Fog Mode Off Pass CGPROGRAM pragma vertex vert pragma fragment frag include "UnityCG.cginc" struct appdata float4 vertex POSITION float2 uv TEXCOORD0 struct v2f float2 uv TEXCOORD0 float4 vertex SV POSITION sampler2D MainTex float4 MainTex ST v2f vert (appdata v) v2f o o.vertex mul(UNITY MATRIX MVP, v.vertex) Gets the xy position of the vertex in worldspace. float2 worldXY mul( Object2World, v.vertex).xy Use the worldspace coords instead of the mesh's UVs. o.uv TRANSFORM TEX(worldXY, MainTex) return o fixed4 frag (v2f i) SV Target fixed4 col tex2D( MainTex, i.uv) return col ENDCG |
0 | How to share microgame with WebGL Publisher? (Unity) I did unity lego microgame tutorials and now I want to publish it with WebGL publisher. I created build files but I can't publish. I get this error I rebuild again to solve this problem. (3 more times..) And clicked quot locate existing building quot again but I still get this error. What should I do? |
0 | How to efficiently keep the player from moving outside the gameobject he is colliding with? I am developing a game with Unity 2017. The game mechanics are as follow Classic top down RPG Movements are UP, DOWN, LEFT and RIGHT Player evolves in a 16 16 map He can dig in the direction he wants to make his way through the map one tile at a time At first I was using a very classical approach using tilemaps, RigidBody2D and BoxCollider2D on tiles and the player GameObjects. Collision detections went fine and my tilemap looked pretty much like that (red being the walls and white the empty spaces) The problem with this approach is that I have to keep in memory the state of 256 tiles in a List lt Vector2f gt and to create the 256 expected GameObjects representing either my walls (which a totally black), or my floor (the empty space). Creating a black GameObject with its own BoxCollider2D for each of the tile seems a little bit overkill. And this brings me to the second iteration of my game to keep in memory only the tiles the player digged. What I would like to achieve efficiently, is to let the player evolve as long as he is colliding with an underlying tile, but stop moving as soon as he doesn't. This is ok This isn't, and player should be placed to previous state. I could take advantage of OnTriggerEnter2d and handle custom collision and response, but I have the feeling that something more simple and more optimized may exists somehwhere in the wild! Thanks to any help provided! |
0 | Using CNN's in Unity via Tensorflow and TensorFlowSharp I have a project that tracks hands made in python, shown here https github.com timctho convolutional pose machines tensorflow I want to effectively import this into Unity. I have generates the .bytes file from the model, but have no idea how to do anything further than this. If anyone has worked with ML Agents or TensorflowSharp in Unity and or would be willing to have a look, this would be great. The image processing stuff would be done probably in a C file beforehand, I just want to know how to run the network. Thanks. |
