0 | Unity, VRChat SDK3, Udon Graph (bug?) I'm trying to create a VRChat world in Unity, using VRchat World SDK3. But I'm getting a strange behavior in Udon Graph assets (as shown by the arrows in the screenshot). Steps I took I've installed the appropriate Unity version (2018 04 20f1) via the hub, Then proceeded to importing VRChat SDK 3 (VRCSDK3 WORLD 2020.12.09.04.44 Public.unitypackage), Then on the project tab, I navigated to the quot Udon quot folder, created a subfolder and inside it I created a Udon Graph Program Asset. Finally, I opened Udon Graph and I added a public GameObject variable. The result was as seen in the image seen bellow the GameObject variable displays a buggy text (the text self (GameObject) shows up twice, superimposed on top of itself as indicated by the arrows in the attached screenshot). |

0 | How to make your own 2D AABB collision system in unity? I can't use the built in unity 2d physics engine for my game, so I tried to make my own using the unity bounds.Intersects, that is working perfectly but my problem is that I don't know how to make the player stop when It collides. Ive tried multiple things like storing the players last position and "teleporting" it back to that position when it collides (That looks choppy). Ive also tried to invert the controls when your colliding (So like W makes the player go down, A makes it go right ect) but that is extremely buggy. How should I do it? |
0 | How can i make fade in out of the alpha color of a material from black to none black? This is script is attached to a black plane. I have a plane and i added to it a material and the plane is in black. When running the game the alpha color of the plane material is changing slowly. The script is working it's getting slowly from dark black to none black. But i want to make some changes It's not my script i took it from the youtube and did some changes the first one converted from js to c second added the fade bool variable. First of all i don't see any meaning setting the variable timer to 10 at the top. Any ideas what is the point ? Second is how can i check when the alpha color value is high enough to do some stuff Enabled true the fpc again. Once it's not black again the fpc is still enabled false. If i want when the alpha color value reached it's max to make automatic fade back to black Now i'm using manual fade bool variable but i wonder how to do it automatic fade in out. using System.Collections using System.Collections.Generic using UnityEngine using UnityStandardAssets.Characters.FirstPerson public class FadeScript MonoBehaviour public float timer 10.0f public FirstPersonController fpc public bool fade true Use this for initialization void Start() Color tempcolor GetComponent lt Renderer gt ().material.color tempcolor.a 1f GetComponent lt Renderer gt ().material.color tempcolor fpc.enabled false Update is called once per frame void Update() timer Time.deltaTime if (timer gt 0) Color tempcolor GetComponent lt Renderer gt ().material.color if (fade true) tempcolor.a 0.1f Time.deltaTime else tempcolor.a 0.1f Time.deltaTime GetComponent lt Renderer gt ().material.color tempcolor |
0 | Make standard Unity 3D objects non transparent I have a problem. When I add a cube or sphere to the scene they are transparent. How can I disable it?

0 | World coordinates on vertical grid game for different aspect ratios (Unity) new to game development and unity so hopefully someone can help. I want to make a 2D portrait mobile game that will have a grid of constant size where units can move on in Unity. This should support different aspect ratios. To do that I was thinking to cut sections at the top and bottom of the screen for smaller aspect ratios. Additionally, I would like the coordinate system to be natural to the grid, so coordinate (0,0) would be the bottom left tile in the grid, (1,0) would be the tile to the right of that,... To illustrate this concept I drew something quickly I tried with a script that resizes the size of the orthographic camera to fit the content horizontally. Problem I had with that is that I couldn't get a good coordinate system on the grid after the camera gets resized depending on the aspect ratio since the number of horizontal world units varies depending on the aspect ratio. Any thoughts on what would be the best way to do this? Thanks! |
0 | In Unity, how do I correctly implement the singleton pattern? I have seen several videos and tutorials for creating singleton objects in Unity, mainly for a GameManager, that appear to use different approaches to instantiating and validating a singleton. Is there a correct, or rather, preferred approach to this? The two main examples I have encountered are First public class GameManager private static GameManager instance public static GameManager Instance get if( instance null) instance GameObject.FindObjectOfType lt GameManager gt () return instance void Awake() DontDestroyOnLoad(gameObject) Second public class GameManager private static GameManager instance public static GameManager Instance get if( instance null) instance new GameObject("Game Manager") instance.AddComponent lt GameManager gt () return instance void Awake() instance this The main difference I can see between the two is The first approach will attempt to navigate the game object stack to find an instance of the GameManager which even though this only happens (or should only happen) once seems like it could be very unoptimised as scenes grow in size during development. Also, the first approach marks the object to not be deleted when the application changes scene, which ensures that the object is persisted between scenes. The second approach doesn't appear to adhere to this. The second approach seems odd as in the case where the instance is null in the getter, it will create a new GameObject and assign a GameManger component to it. However, this cannot run without first having this GameManager component already attached to an object in the scene, so this is causing me some confusion. Are there any other approaches that would be recommended, or a hybrid of the two above? There are plenty of videos and tutorials regarding singletons but they all differ so much it is hard to drawn any comparisons between the two and thus, a conclusion as to which one is the best preferred approach. |
0 | Decelerate moving platform at targets I'm trying to make a moving platform move at a constant speed and then when it is near the target start to slow down, I have trying to do this with Lerp, but I'm not satisfied with the results because of two reasons it goes way too fast between targets, and way too slow near targets. Also, when it reaches a target it immediately boosts off in the opposite direction. What I want to achieve is for the platform to move steadily between targets, decelerate near targets, and when reaching a target start to accelerate back to the steady speed. What is the best way for achieving this? Lerp, Smoothstep, other? Thanks!

0 | How can I optimise my game and its game objects? I have a 3D game in Unity and I use blender to design models for it. My game has a feature where if you click a button, an object is cloned. An example from my game is a tree that is cloned around 100 times with different sizes and positions to form a forest. The issue is that after a few presses of the button, the game starts to really lag. Is there a way to optimise the game in Unity or optimise the models in Blender to reduce this lag? I use the instantiate function in Unity to do my cloning.

0 | Trouble Positioning Object In World I have a lightning effect that travels from point A to point B, I am having trouble placing placing point B correctly. As you can see from the object hierarchy the points (LightningStart, LightningEnd) are nested 3 levels deep. parentReaction.affectorWidget.transform.positionis the position I would like the object to be at. As you can see below I have tried setting the position equal to the other widgets transform, I have also tried using transform.InverseTransformDirection and transform.TransformDirection in varying combinations, I have tried many options the code below is just me going back to basics to see what I missed. I am not sure even which object I am supposed to call TransformPoint from, the Widget with the effect )(Point A) or the Widget at Point B? Given the above scenario how would I position LightningEnd so that is at the same position as parentReaction.affectorWidget.transform.position? I understand this is a very common question and I have read many previous questions related to this but two hours later, I would just like to know how its done so I can understand where I am getting this wrong.

0 | Creating a master server for Unity game (Unity 2017) I have a basic FPS game made in Unity. I am using the Unity NetworkManager, NetworkManagerUI and NetworkIdentity components that came with Unity. The game is working fine on my local network when I make one pc a client host and other a client. It is also working great using the 'Mulitplayer' service that is free with Unity (for up to 20 max over all games projects etc, and is supposed to be only for testing I believe) I'm 99 sure it is possible to run a 'server version' of my app on a pc in my home, and make this into a dedicated master server, but I cannot find much at all from Unity officially regarding this (It seems to always point me to just extending my deal with them to get more players into the server they provide, for which the costs are 1000x more than the budget I have for the game) Before Unity were offering these pricey services, there was info such as this https unity3d.com master server But it says that is only compatible with Unity 3.x I've asked this question 2 3 times already on the Unity Answers site, and there are no answers at all. I've also browsed it for similar questions and all those seem to be unanswered or way out of date. As I stated last time I ask this, I know thatt Rust game is made with Unity. In past, I downloaded (officially from Facepunch, the devs of Rust) the 'Rust Dedicated Server' application, which I ran on my desktop PC (with fibre network connection) and then I was hosting a server in game. The server ran smooth as silk, so for my game I dont think i would need an actual modern server machine or direct internet connection (otherwise, how did Rust manage it??) So as I say, I have the network functionality all up n running. But the last piece of the puzzle is that I'm using Unity's Mulitplayer Service, and this only allows 20 max concurrent players. This isn't quite enough, as I'd like to have at least 50 if possible. Also I would end up running 10 20 of these so that there is a choice of 'rooms'. Ideally I would be able to let people download and run their own just like Rust. Before I got to this stage, I was trying to make one user become the Client Host, but I couldn't figure out how the other clients would be able to tell what is the IP address for the host. Please can anybody help me, I feel like I've gotten the majority of the way there but now I can't get any further by myself. Many thanks! |

0 | How to proper manage a world composed by multiple scenes? I have a UI only scene for my game that have only Unity UI elements (those that need a Canvas), separate from the world scene. In the UI scene I have a MonoBehaviour that manage all the effective actions and all the interactions between different UI elements, and In the world scene I have another manager responsible for controlling all the other things in the game scene. This design worked pretty well until I faced the following situation in a specific moment the player need to click in BoxColliders that are in the world scene but it is actually a UI related action. This action of clicking in these BoxColliders are essentially the player clicking in buttons that in this case happen to be 3d objects that need to be composed in the environment, thus need to be in the world scene. In the situation described above the clicks on those BoxColliders should be managed by the UI Manager, that is alive in the UI scene. So the problem is how should I approach this whole situation without breaking a lot of clean code rules? What is tipically done when developing in Unity to solve this kind of problem when you need a reference for an object that lives in another scene without keeping a hard reference for this object (or just calling GameObject.Find in the scene startup)? |

0 | Animation imported from Maya has interpolation issues I have imported animation from Maya (.fbx) and the curves for the animation in Unity are very different than in Maya. I can clearly notice a flicker for few seconds when I am scaling the object (0 to 1) in loop. The curve for scaling is shown below. The rest in the animation work fine except for the scale. The problem is that Unity adds interpolation automatically to these curves which is why it creates an issue. I have selected the keys in the curves for the scale attribute and quot Both Tangets gt Constant quot , but it did not have any effect. How can I fix this? |

0 | How to increase the difficulty setting as close as possible to maximum difficulty automatically? I have a simple 2D version of Mini golf. The goal is to manage to clear each level in the least amount of shots, the ball is bouncing at most 3 times (stops on the 4th hit) from a wall but not reducing in speed, there is no out of bounds and no obstacles that would remove the ball. Now I would like to add some water instant death obstacle at the most annoying places. How do I find those places? The player can aim in a 360 radius, if I set the goal of managing a given level in 2 shots, there are 129,600 ways of how the player could shoot the ball. While it should be possible to simulate all of those shots fairly easy, I don't want to add randomly water and check if the level is still possible to clear, rather simulate the level, record all places the ball went over and place on the spots with the most hits water. What is the best strategy a good algorithm to blockade the most ways but to guaranty that at least one way stays clear? Does the strategy change significantly if moving obstacles (on a fixed path, same rule for bouncing as normal wall) are included? |

0 | LOD culled gameobject still interacts with raycast The camera is sort of top down and the player can move objects around, rotate them, delete them etc. I use a raycast to check what was hit when the player clicks. But some objects are culled by the LOD group when far away, but the LOD group only disables the renderer, not the colliders, so it still interacts with the raycast. This means a player can move or delete an object that they can't even see. I've tried looping through all the renderers in the lod group and using renderer.isVisible but it doesn't solve the problem of collision and raycasts. I'd really rather not poll isCulled every frame in update either because there are thousands of gameobjects, that would be horrible for performance.

0 | How to detect when the mouse is over a particular enemy collider, without falsely selecting bullet colliders? I have an enemy shooting around. My game mechanic involves hovering over the enemy with the mouse to drain its health. While the enemy is moving, you need to follow it with your mouse. If you don't succeed to follow it and the mouse leaves the enemy's collider, the enemy's health should be refilled.

0 | Unity Messages in Compound Colliders Lets say I have a 2D character with two colliders a circle collider that represents the feet, and a box collider that represents the body. Lets say that the character is currently standing on the ground, i.e. only the feet collider is in contact with the ground collider. According to the Unity manual, I will receive an OnCollisionEnter2D message. That message contains a Collision2D object that contains an otherCollider field of type Collider2D. I don't see anything in that object that would tell me which of the two colliders the body or the feet initiated the message. So my question is this how do you figure out which collider in a compound collider initiated a collision trigger message? |

0 | Calculate heading required to turn ship so that its weapon can fire at target I have a ship, the ship travels towards a heading (vector3, blue arrow) with an arbitrary speed. The ship has a weapon on the side, the weapon can point in any direction, except straight forward backwards from the ship heading. (In example image the weapon is a perpendicular 90 right). The weapon has a firing arc, in n degrees (so, n 2 degrees in either side from the weapon "point direction"). Given a target at any position on the same side of the ship as the weapon (red circle), how do I rotate the ships heading so that when oriented towards the new heading (in this example, the yellow arrow), the target is inside the bounds of the firing arc? (The ship cannot rotate on the spot, it turns by driving forward towards a heading, like a simplified aircraft) While my game is set in full 3D, I think a 2D solution will be more than enough. I use Unity, and C , but I'm thankful for any solutions. Edit To clarify, I am looking for the "math based" solution, collision checks etc isn't really feasible. |
0 | Creating a curved mesh on inside of sphere based on texture image coordinates In Blender, I have created a sphere with a panoramic texture on the inside. I have also manually created a plane mesh (curved to match the size of the sphere) that sits on the inside wall where I can draw a different texture. This is great, but I really want to reduce the manual labor, and do some of this work in a script like having a variable for the panoramic image, and coordinates of the area in the photograph that I want to replace with a new mesh. The hardest part of doing this is going to be creating a curved mesh in code that can sit on the inside wall of a sphere. Can anyone point me in the right direction? |

0 | Unity 2D Inconsistent jump height in game window Whenever I start the unity editor and play it in the Game windows, sometimes the object can jump higher sometimes it is just small jump. I didn't change any value in my script nor changed it in inspector window. It usually happens when I restart the unity editor or having my computer shutdown restart and reopening the project. Here are the jump code void jump() if (isInGround) float currentJumpForce jumpForce Mathf.Abs(rigidBody.velocity.x) 3.53f rigidBody.AddForce(Vector2.up currentJumpForce) animator.SetTrigger("isJump") I place the code inside the FixedUpdate method, for what I have read the physics calculation should be inside FixedUpdate right? private void FixedUpdate() if (Input.GetKeyDown(KeyCode.UpArrow)) jump() I have read many are having similar problem, but it really doesn't answer this question. UPDATE I forget to explain it in the question. The jumpForce is calculated based on the velocity of the gameObject has. I capped the velocity to certain speed based on this code void accelerate() if (rigidBody.velocity.x lt maxSpeed) rigidBody.AddForce(Vector2.right acceletateForce) where maxSpeed is a constant. I know this is probably not the accurate way to cap the velocity, or is it? Maybe this is where it gets messed up? I just kinda assume the velocity is the capped from the camera movement and the 'display' or the movement of the screen. It seems the same to me. |
0 | In unity, some part of mesh doesn't show only in play mode This is screenshot of not playing mode. You can see the the speedloader and bullets inside of the revolver. And this is when playing mode. As you can see, I can see the speedloader and bullets in scene view, but not player's camera. Sometimes, it disappears in scene view either! I made this model same as other weapons, but others are working fine. Only this weapon causes this problem. All weapons that I made are based on same model and rigs, and I kept the weapon's scale fit as same as possible. I tried move the camera and scale down a little bit, but still couldn't saw. Why this is happening? How do I solve this? Any advice will very appreciate it. |
0 | Queueing with Unity's NavMeshAgent I have created a strategy game where the units use Unity's NavAgent pathfinding and flocking algorithms. This works well. However, I need to add queueing so that units will queue sensibly. This works most of the time, but it isn't perfect and I want to know if there's a better way of doing it. My first draft was to simply check which unit is closest to the destination, but this caused issues because a group might be navigating around an obstacle and the unit closest is at the back of the queue... so the whole group stops. Second draft checked the distance to destination based upon the length of the path each unit had to take. This works far more often, but sometimes still has issues. Sometimes the same problem happens, but much less often. The one who is supposed to be moving stops, and so the entire group stops. There's also a problem I've noticed, where the waiting units could sometimes benefit from rotating, even if they shouldn't be moving. Unfortunately they sometimes get stuck and will wait before they can move, to rotate. If they could rotate when forbidden from moving it'd help considerably too. What I need to know... How can I make Unity NavAgent's queue, so that they will wait for the other agents closest to the destination to move first? How can I ensure that this does not stop agents from rotating while in a queue (rotating may move them into a better position in the queue). Code Unit Movement Function private void Movement() Unit is moving. if (moveVectors.Count gt 0) navAgent.isStopped false Check for whether to wait in queue. Vector3 nextVector transform.position nextVector transform.forward speed Time.deltaTime foreach (Unit unit in list) if (unit ! this amp amp unit.moveVectors.Count gt 0 amp amp Vector3.Distance(unit.transform.position, nextVector) lt (unit.footprint footprint) amp amp PathDistance(unit) lt PathDistance(this)) navAgent.isStopped true return There's a bit more to Movement, but it's not relevant so we'll ignore it for now.

0 | How can I uniquely identify a GameObject in Unity? I'm trying to serialize and deserialize my custom classes with Unity. I've got an ISerialize interface that mandates the class can Load() and Save(), so then I setup one master class to iterate across everyone and find the ISerialize components and trigger them to Load() and Save() correctly public class SerializationTest2 MonoBehaviour, ISerializationCallbackReceiver GameObject gameObjects null Start is called before the first frame update void Start() gameObjects UnityEngine.SceneManagement.SceneManager.GetActiveScene().GetRootGameObjects() comment Update is called once per frame void Update() public void OnBeforeSerialize() Debug.Log("Unity is serializing... saving state!") foreach (GameObject gameObject in gameObjects) Save(gameObject) public void OnAfterDeserialize() Debug.Log("Unity finished serializing... loading state!") foreach(GameObject gameObject in gameObjects) Load(gameObject) private void Load(GameObject gameObject) Debug.LogFormat("Found 0 ", gameObject.name) ISerialize serializers gameObject.GetComponents lt ISerialize gt () foreach (ISerialize serializer in serializers) serializer.Load() int nChildren gameObject.transform.childCount for (int i 0 i lt nChildren i ) Load(gameObject.transform.GetChild(i).gameObject) private void Save(GameObject gameObject) Debug.LogFormat("Found 0 ", gameObject.name) ISerialize serializers gameObject.GetComponents lt ISerialize gt () foreach(ISerialize serializer in serializers) serializer.Save() int nChildren gameObject.transform.childCount for(int i 0 i lt nChildren i ) Save(gameObject.transform.GetChild(i).gameObject) So this works GREAT and exactly as intended I get a list of all the top level root objects on Start(), then I get the serialize deserialize callback. I iterate down the tree of GameObjects for each root and get everyone. The idea here is that this class will eventually open an XML file and save to that file for serializing or will load from that file for deserializing. I need to build that XML hierarchy, though. I could have multiple instances of a class scattered across a bunch of different GameObjects, so I need some way of identifying which GameObject I've currently got so I can serialize deserialize to the correct components for that GameObject. The problem is that, when I use the above code, I get UnityException GetName is not allowed to be called during serialization, call it from Awake or Start instead. Called from MonoBehaviour 'SerializationTest2' on game object 'Registrar'. See "Script Serialization" page in the Unity Manual for further details. So, then, how do I uniquely identify the GameObject I'm currently on? If I can't call gameObject.name, what should I be calling? EDIT As an example, consider two enemies one has a scale of 2x the other and a hitDamage of 2x the other, but they otherwise use the same EnemyAttack script. I need to deserialize the hitDamage values to the correct GameObject, but if I can't use the GameObject's name during the serialization process then I don't know how I'm supposed to distinguish the two. |

0 | Why are my animated objects (from Blender) always playing at the global origin in Unity? I created and animated a sledgehammer in Blender 2.67b using an armature. The sledgehammer has one animation (created using the Action Editor) called "Idle". I parented the imported sledgehammer to an empty GameObject and set the sledgehammer's position to (0, 0, 0). I then moved the parent GameObject to where I want it in the scene. When I launch the game, the animation plays but the sledgehammer child always re positions itself to be at the global origin, no matter where I place the parent GameObject. See the image below Notice how the sledgehammer's position goes from (0, 0, 0) to ( 1087, 3, 1149). The armature has a single bone and has the sledgehammer object as a child. I've spent about 4 hours looking this up on the Internet, but it seems like parenting the animated mesh to an empty GameObject worked for everyone else except me. Anyone else experience this?

0 | UI background animation makes camera render beyond canvas, need fix? I have a background animation for a menu where I have to make the background larger than the canvas and drag it over it.

0 | How to rotate an object based on the movement and angles of Lifters I have Lifters that quot carry quot an object. I want the object to move and rotate based on how those Lifters move. Requirements include Supporting 1 4 Lifters at any side of the Object (e.g., both on one side, opposite, so on can't make any guarantees about their positions relative to the object) Supporting any orientation of the Object (e.g. the Object could be flipped on its side, sideways, or upside down can't make guarantees that Forward is always facing forward, etc) As such I implemented this by having the object move by setting its velocity to the average of the Lifters' velocity. Now, if not all of them move (or if there's a disparity in their velocities), I want the object to rotate, like so This is done by keeping track of how much an individual lifter has moved in a frame from the Object's position, and calculating the angle via m Angle Vector3.SignedAngle(lastPos transform.position, currentPos transform.position). This quot movement angle quot I add up for every Lifter and then at the end, Rotate the Object via Transform.Rotate(Vector3.up, m Angle). However, this approach has some problems Calculations are done along the Y axis and therefore does not angle the Object up or down if the Lifters have different vertical positions, m Angle actually overshoots, but I found simply dividing m Angle by the number of Lifters made it perfectly accurate. I do not know why this works. Because I want this to rotate the object in quot 3 dimensions quot , I have attempted to calculate the quot euler angles quot of each Lifters' movement via Vector3 oldDisplacement lastPos transform.position Vector3 newDisplacement currentPos transform.position Quaternion rotation Quaternion.FromToRotation(oldDisplacement, newDisplacement) m EulerAngles rotation.eulerAngles And then at the end, I rotate the Object based on these quot movement angles quot transform.Rotate(m EulerAngles, Space.World) This works in three dimensions, however it is off in the same way that m Angle was before I divided it. It rotates the object too far. On top of that it seems to produce rotations along axes that have no displacement. I want the object to only rotate exactly by the angle created by the Lifter's movement. This should keep it quot synced quot to Blue instead of rotating past as you see here. When I check how much rotation Blue is adding per frame, I get an output like so Blue is adding (0.000, 359.507, 0.066) on movement ( 0.015, 0.000, 0.000) Despite moving solely on the x axis, there is a z euler angle being created, and the y euler angle of 0.493 degrees is too much for 0.015f movement. I do not know why rotation.eulerAngles is inaccurate in my usage. The only issue I can perceive is that since the Object's position is also moved at the end, the angle calculation assumes it is not moving and generates a larger angle (e.g., perhaps newDisplacement should be something like currentPos (transform.position m Body.velocity Time.deltaTime) ). However, removing the Object's movement from the finalPosition of the Lifter seemingly has no effect. Or perhaps there is some finite precision in Quaternion.FromToRotation? Or my math is incorrect in some way? I'd love a sanity check on the code or approach or if I should approach this problem from a different perspective. EDIT Here's an example gif of the functionality with m EulerAngles code (so the rotation overshoots, but works in 3D also I recorded the gif at lower fps that's not the game's framerate) |

0 | How to draw texture with unlit effect on surface base texture I am writing a shader to my Unity game and I want to have effect this type of effect Base texture, for example, skin of character is a texture that will use shadows, lighting.

0 | Exposing type definitions to modders in Unity Note that this question is not about modding assets data and not about security, I plan to rely on community trust. I don't know much about DLL's and I was wondering how I can provide interface and attribute definitions for modders. For Kerbal Space Program modders only have to reference the Assembly CSharp.dll, UnityEngine.dll and UnityEngine.CoreModule.dll files of a games build, to create and compile their own DLLs. Are there certain things I have to do, to mimic this behavior, or does this work out of the box? Are there gotchas to this approach? Will a mods DLL, that was compiled using an older version of Assembly CSharp.dll, break if the Assembly CSharp.dll is updated, even though no types relevant to the mod changed? Will modders be able to use Visual Studios debugging features for their DLLs? Is there a better approach to provide type definitions? My question is related to this question. But I would argue that that question is kind of broad, while mine is about one specific aspect. Might not be needed for the question, but here are the two levels of modding that I would like to support for my game 1. Easier modding I want to compile .cs files of modders that implement special interfaces like IAbility, IItem, etc. I will use Roslyn or cs sript to do so. 2. More advanced modding I also want to load .dll's that modders compiled, allowing them to register their own Types in the games DI Framework, mark methods classes with attributes like CallMethodOnLevelLoad and use Harmony. |
0 | Food Game using Online Searchs I am thinking of making a simple game with Unity. The aim would be to keep a person healthy by feeding it well balanced food and drinks. Rather than hard codding every single type of food or drink I can think of I was thinking of letting the player choose any type of food he wants and then screen the internet for it's calorific value, saturated fat, sugars etc ... This would make the game much more enjoyable than being limited by the foods I can think of. I was wondering how you would go about doing that ? Could I use an API to extract data from google or wikipedia. I noticed that when you type " food calories" in Google you get a return from the Wikipedia page like this Obviously, there is a way of extracting the data from Wikipedia and I could automate the searchs by taking the player's entry as a string and running a search with it. How would one recommend going about this ? Also, is it safe ? Thanks |

0 | Keeping high scores on Unity web player I want the player to be able to save his score when she makes it into top 10 of high scores. Upon success, player will be asked for a name to submit. This does not need to be unique per player. I just want a basic global score board available for everyone who plays the game via web player (from github.io page of the project). When searched for how to keep high scores, I came across PlayerPrefs. On Web players, PlayerPrefs are stored in binary files in the following locations Mac OS X Library Preferences Unity WebPlayerPrefs Windows APPDATA Unity WebPlayerPrefs As far as I understood, the results are kept in local machine and won't be same for everyone. So it's good for keeping track of your own score, locally. As a placeholder in the current version of the game, I keep the scores in a local .txt file in the project directory. Can I succeed with this approach and use the github.io server to maintain a global scoreboard or do I necessarily need a database to achieve this goal? |
0 | Adding some new velocity to player in FixedUpdate. Should I use FixedDeltaTime or nothing? I am trying to learn how to move objects in Unity without using the built in features like AddForce etc. Some tutorials on Unity website (and other places) is where I have got most of my 'knowledge' so far from. This script for moving players (in topdown Space SHMUP) has been working fine for me and includes acceleration and artificial drag (basically 'smooth' movement, or like being on ice). I'm sure this code is overly long, bloated, inefficient and in most cases downright wrong, but it is written for me to understand it, rather than simply using Unity Prefabs and AssetPackages i download from Store. QUESTION Do I need the Time.fixedDeltaTime mutlipiers when calculating my 'delta v' values here. And also what about on the drag part at the bottom. As usual all help and comments are greatly appreciated.

Then at this line 39 if (transform.localPosition.x gt begin.x) The value of the x of the transform.localPosition is 3.039021 and the x of the begin is 540 So it's getting inside and move the transform. Then when the transform has finished moving I see on this line if (transform.localPosition.x gt begin.x) The transform.localPosition x value is 540.7267 and the x value of the begin is still 540 So now it will not get inside and will not move the transform anymore. But two wrong things happened The transform stopped moving but it didn't move to it's original position only close to it. Because it didn't move to it's exact original position then the localPosition x and the begin x are never equal so the this will never be true if(transform.localPosition begin amp amp goBack) And the flag atOriginPos is never true. I want the transform to move back to it's original position and then when it's reached the original position set the flag atOriginPos to true. |

0 | How do I run functional tests against my Unity3D game? Context I am continuing some legacy code for a game in Unity3d, and I want to write some functional tests meant for regression, to ensure I don't break things when implementing new things or when refactoring. I already know there is the 'Unit Test Tools' suite for Unity3d available as an asset. I have used it as a unit test suite, so I test my models (classes). Example of what kind of test I am thinking about For "functional test" I mean things like this Run the program When in the menu scene, assert there is a button that says "start" Click it Then assert a new scene is loaded Assert pixel XXX is red Click in coordinate XXX Assert now that the pixel changed to green etc. Questions Q1 How do I write and run functional tests for my game? Is this also typically done in the UnityTestTools (UTT)? Q2 If UTT is more for Unit Testing, then is there a separate suite for functional testing? Which one? Notes I'm targetting Android, and running Unity5.3.1f1 |
0 | Can't change materials of model from FBX I was used 5.x before, and that version when I loaded FBX, Unity generated each material automatically, so I can change them like assigning textures or change shader. And now I switched to 2017.3, and when I imported FBX, now Unity didn't generate materials anymore. I can see the properties of each material but every parameter is locked. It seems materials are inside of model and can't change like animation clips. Some of model has multiple materials, so I can't generate manually and assign them. I'm creating mobile game so I really need to change the shader to mobile shader, not standard(PBR). How to change materials of model from FBX in Unity 2017.3? Note that model created from Blender 2.7c and exported as FBX. |
0 | How is Unity's Command supposed to behave? Here's a very simple class call hierarchy public class NetworkPlayer NetworkBehaviour public static NetworkPlayer localPlayer get private set Command public void CmdTurnDone() Debug.Log("Turn done! isServer " isServer " isClient " isClient " isLocalPlr " isLocalPlayer) public class SomeMonoBehaviour MonoBehaviour void Update() NetworkPlayer.localPlayer.CmdTurnDone() When Update() gets executed on the host, it outputs as expected Turn done! isServer True isClient True isLocalPlr True Now, when Update() is executed on the remote client it outputs the following at the remote client's log only. However, the message does not appear at the server's logs Turn done! isServer False isClient True isLocalPlr True What puzzles me is why the message appears at the remote client's log only. If I'm not mistaken, calling CmdTurnDone() at the remote client should execute it on the server. But why does the log message appear at the remote client's log instead of on the server's logs where it is executed? Is it valid to call CmdTurnDone() from a MonoBehaviour? Do you have any ideas why it's behaving like this? Is this the intended behavior? Thank you. |
0 | How to displace a segmented line along a sine wave with Shader Graph? I have a mesh made of three identical cylinders (conceptually just line segments with a non zero thickness) crossed over each other at 60 degree angles, so the ends describe the points of a regular hexagon. The cylinders are divided into a lot of segments, which I'd like to displace in a sinewave pattern. The pivot is in the center of the mesh. My concept is pretty straightforward Subtract object position from vertex position to get vertex position relative to the pivot (VPR). Normalize VPR and swap the X and Y to get a vector in the XY plane perpendicular to the orientation of the cylinder. Take the magnitude of VPR, multiply by a V1 parameter (Waviness), then take the sine. Multiply the sine by the perpendicular orientation vector to get the displacement. Add the displacement to the vertex position. Assign result to master node's vertex position. This really feels like it should work. Each cylinder should be distorted along a sine wave, with the magnitude of the distortion increasing the further it gets from the center, so I end up with three wavy lines crossed over each other at 60 degree angles. Increasing Waviness should increase the frequency of the wave, as the base value is multiplied by it before feeding into the sine node. Instead, things curve just a little bit at a low Waviness, but as I increase it the cylinders get both thicker and longer, neither of which should be happening, and start wrapping themselves around the mesh in weird patterns. I have no idea what I'm doing wrong! Here's my graph setup, with the mesh assigned to the preview so you can see what a mess it's making of it Any ideas how I can fix this? |
0 | Unity Mesh and Collider not aligned on rotation I have a GameObject with a mesh and a collider. When I rotate the object the mesh and the colider do not act the same way and when the GameObject is rotate 65 degrees on the z axis the mesh and the colider are no longer aligned.

0 | Player with Character Controller and children colliders won't collide properly I have a player that consists on a root object with the Character Controller attached and some children with its components. Those have box colliders attached. When moving the player I want to be able to collide with other objects using the box colliders, but it won't, instead it will only collide with the Character Controller. As you can see in the image, the red object didn't stop when the collider crashed with the framed cube, but it did when it did with the Character Controller. There is any way to use the player colliders instead of the Character Controller for collision detection? |
0 | How do I cover a plane in a bumpy foam material effect? I need to fill a weapon bag with foam material. This is what it should look lik The material in the upper part of the bag looks like this I'm using HDRP. How could I do this? Thank you! Edit I have played around with Parallax Occlusion mapping, and I got this result. Edit2 I am not sure if I use the Pixel Displacement as it has been suggested to me. Also, I'm not sure if I use it the correct way I have created a Height map and put it into the Height map slot. This doesn't create any effect. I have to put the same map into the Base map slot in order to see the effect. If I put a black image into the Base map slot or if I choose Black as the Base color, no effect is visible. I don't understand why this is so. I think even if my Base map is black, the Shader has pixels that it can move. This is my height map Edit 3 It was suggested that I should use a normal map. This doesn't look at all what I expected. The normal map was created from the Height map using an online tool By Philipp's answer I found out that the normal map alone is not enough. |
0 | How to pause audio playback when a breakpoint is hit or resume afterward? When my code hits a breakpoint, audio that was previously started (via an AudioSource) continues to play while the threads are paused. I'm using a coroutine to query the status of the AudioSource, and update my UI. Because the audio continues to play, then after I've spend some time stepping through code the next frame tick when Unity gets control back runs the next iteration of this coroutine, which updates the UI. I never get to see the in between states. Because it's a relativley short audio clip it's usually finished playing before I've finished stepping through the code. I'm using Unity 2018.4 with VSCode and the Debugger for Unity extension, if that helps. I'm quite lost at what to try here. Looking for issues with Unity's AudioSource and breakpoints yields a lot of varied information about audio issues in general in Unity. I've tried using Debug.Break(). It pauses the Unity editor, which can be useful but has the following caveats it requires extra effort on each breakpoint that requires enabling (if the call is not there already) it requires manual intervention to resume the editor once you've finished stepping through code because it is code, it cannot be added after Unity is playing, e.g. to additional breakpoints that are added once debugging has started Does Unity have a mechanism that enables this behaviour that I've just missed? If not, what's an appropriate alternative approach? |
0 | AudioSource.Play() outputs only noise from the sound clip I'm trying to reproduce a sound clip on the AudioSource of a game object by using the .Play method. What i'm trying to do is a card game of sorts, but with each card being a different section of a song of a genre. I combine different cards with different genres and when i press play, the combination should start playing, but now when the play button is pressed, only noise comes out. The code for the start method looks like this public class AudioStart MonoBehaviour AudioSource thisAudioSource Start is called before the first frame update void Start() thisAudioSource this.GetComponent lt AudioSource gt () Update is called once per frame void Update() if (playButton.playPressed) thisAudioSource.Play() else thisAudioSource.Stop() The way i'm doing it is by having a button that on click changes a bool to true or false depending if there is sound playing (the truth check on the if statement). The AudioSource outputs to an AudioMixer on a specific group under the master group (which group depends on the slot that the card is dropped in). The AudioStart script is attached to different game objects with a different audio clip each. I've also noticed that when i try to reproduce two cards, only one AudioSource gets played. Any help would be appreciated. Thanks! |
