0 | First object jumps on re entry of second colliding object The scenario is that I have two objects Object A and Object B. The Object A is lying on the ground and when Object B enters the collider of Object A, the Object A moves (only X and Z axis) with Object B. The movement works well with the script shown below. The issue is that most of the time, the Object A's initially position shifts by few meters whenever Object B enters its collider. I feel it is related to offset position. What should happen is that, Object A should be the same position when Object B enters the collider and move along with Object B only when Object B moves. So how do I fix this? private Vector3 offsetPosition public Transform ObjectB public bool ObjectB Collision false void Start () offsetPosition ObjectB.transform.position this.transform.position void ObjectB HasEntered() offsetPosition ObjectB.transform.position this.transform.position Update is called once per frame void LateUpdate () if (ObjectB Collision true) this.transform.position new Vector3 (ObjectB.transform.position.x, this.transform.position.y, ObjectB.transform.position.z) new Vector3 (offsetPosition.x, 0, offsetPosition.z) public void OnTriggerEnter (Collider col) if (!enabled) return if (col.gameObject.name quot Object B quot ) ObjectB HasEntered() ObjectB Collision true public void OnTriggerExit (Collider col) if (!enabled) return if (col.gameObject.name quot Object B quot ) ObjectB Collision false |
0 | Unity ECS How do I stop an entity from spawning twice? I am implementing a flight dynamics model using Unity's built in ECS package, Entities, and I keep running into one particular issue where the aircraft I'm trying to spawn gets converted into an entity twice. Essentially, I have a singleton Monobehaviour that handles setting up the aircraft entity from a GameObject Prefab. Here's the script public class GameManager MonoBehaviour private BlobAssetStore blobAssetStore public static GameManager main public GameObject planePrefab public float zBound 0.0f public float throttleMaxBound 1.0f public float alphaMaxBound 20.0f public float bankMaxBound 20.0f public float flapMaxBound 40.0f public float throttleMinBound 0.0f public float alphaMinBound 0.0f public float bankMinBound 20.0f public float flapMinBound 0.0f public State state public Properties prop Entity planeEntityPrefab EntityManager manager private void Awake() if (main ! null amp amp main ! this) Destroy(gameObject) return main this manager World.DefaultGameObjectInjectionWorld.EntityManager blobAssetStore new BlobAssetStore() GameObjectConversionSettings settings GameObjectConversionSettings.FromWorld(World.DefaultGameObjectInjectionWorld, blobAssetStore) planeEntityPrefab GameObjectConversionUtility.ConvertGameObjectHierarchy(planePrefab, settings) SpawnEntity() private void OnDestroy() blobAssetStore.Dispose() void SpawnEntity() Entity plane manager.Instantiate(planeEntityPrefab) prop new Properties( 16.2f, 10.9f, 2.0f, 0.0889f, slope of Cl alpha curve 0.178f, intercept of Cl alpha curve 0.1f, post stall slope of Cl alpha curve 3.2f, post stall intercept of Cl alpha curve 16.0f, alpha when Cl Clmax 0.034f, parasite drag coefficient 0.77f, induced drag efficiency coefficient 1114.0f, 119310.0f, 40.0f, revolutions per second 1.905f, 1.83f, propeller efficiency coefficient 1.32f propeller efficiency coefficient ) state new State( 0.0f, time 0.0f, ODE results 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, roll angle 4.0f, pitch angle 0.0f, throttle percentage 0.0f flap deflection ) float3 position new float3(state.q1, state.q3, state.q5) manager.SetComponentData(plane, new Translation Value position ) After a little bit of commenting here and there, I was able to determine that the following two lines are responsible for creating two separate entities, though the latter is the only one I'm capable of manipulating using the system. It's also worth mentioning that these two entities are virtually identical in the Entity Debugger, except for the fact that the first entity contains the quot prefab quot tag. planeEntityPrefab GameObjectConversionUtility.ConvertGameObjectHierarchy(planePrefab, settings) and... Entity plane manager.Instantiate(planeEntityPrefab) Is there a way to spawn this entity without both showing up in the debugger or is this unavoidable? If not, is there a way to remove the entity with the quot prefab quot tag from the world? Thanks! ) |
0 | Method subscribed to an event is called twice for every time the event is raised I am trying to make an inventory system in Unity with ScriptableObjects and a text driver that displays the contents of an inventory. So far the code looks like this An InventoryObject is defined as having a quot Container quot List of ItemObjects (simple scriptable objects, they just have a little information on the object as its sprite, its name, and whether or not it is stackable) and some methods to properly add or remove items (taking item stacking into account) from that list. https pastebin.com t4P3aGmi A PlayerInventory is a script that will be carried by the player's character. It contains a method for adding items collided with to its assigned InventoryObject instance. It also contains an OnItemPickedUp event that takes its InventoryObject instance as a parameter and passes it to listeners like UpdateDisplay. OnItemPickedUp is raised whenever a collision with a compatible item happens. https pastebin.com RsV7XYPp An UpdateDisplay script that listens to the OnItemPickedUp event and subscribes the ProcessInventoryToSingleString(InventoryObject inventory) method, that subsequently calls several methods to transform the contents of the InventoryObject's Container list into a single, formatted string. https pastebin.com N0nsvcWH The items are represented by giving a GameObject with a collider2D, aSpriteRenderer and script that contains the particular ItemObject's data and sets its SpriteRenderer's sprite to the ItemObject's. The problem I'm having is that the method subscribed to the event is being called more than once for each time the event is raised. as shown by the debug logs. Sometimes it's called twice, sometimes even four. This results in my UI display showing more items than there are. https files.catbox.moe afa467.mp4 https files.catbox.moe 6oxh9b.mp4 Here are pictures of the console debug logs I appreciate any help. EDIT These errors also appear. I'd like to believe that they're unrelated. |
0 | Most efficient way to modify character mesh at run time What is the most efficient way in unity to alter the mesh of a character in this scenario When the player pick up an item A part of the mesh should be replaced, for example, the left arm is swapped by a robotic, rock, wood etc... arm. The animations are the same. Other parts may change in a different way, for example, left arm stone right wood.(This happens in a different pick up later) There is no problem if the game slows for a sec as this not happen "in action". One more thing In general terms, what are the thing to consider when doing these modifications in terms of performance?(Such as polygons of the mesh, resolution of textures...) Will many changes end up in consuming memory or other resources? |

0 | Why aren't my Unity rotations working properly? I'm experiencing a rather annoying bug and I was hoping someone could offer some help because this just isn't making sense to me. I have a Ballistic script that tells the bullet to move in its local forward direction, which should be whichever way the gun is pointing. I have a PlayerAttack script that calls for a bullet to spawn with OnShootEnter(). It sets the bullets position to that of a bulletSpawn transform, which is a child of the gun. OnShootEnter() is being properly called and bulletSpawn is properly assigned and yet, when the bullet spawns, its facing Vector3.forward, instead of it facing bulletSpawn.forward. These are the only two scripts affecting the bullets spawn, rotation, and direction. Everything looks in order to me what am I missing? public class PlayerAttack MonoBehaviour public GameObject bulletPrefab public Transform gun public Transform bulletSpawn public float damage void OnShootEnter() GameObject bullet Instantiate(bulletPrefab, bulletSpawn.position, bulletSpawn.rotation) public class Ballistic MonoBehaviour public GameObject model public float range public float accuracy public float speed Vector3 dir Vector3.zero void Start () model.transform.SetParent (this.transform) dir transform.forward void Update () transform.GetComponent lt Rigidbody gt ().velocity dir.normalized speed range Time.deltaTime if (range lt 0) Destroy (this.gameObject) |

0 | Can I use different Tile Sprite Sizes on the same Tilemap? My partner and I are creating a 2D RPG with D amp D elements with Unity. I am very new to Unity and making games in general, apart from 2 games which I created with Java and the rougelike tutorial which I did with Unity. For this university project we have 4 months and my partner has the job creating tiles, sprites, sound and music. I will program the game. My question is Can we create 32x32 tiles and 64x64 sprites in the same tilemap or does everything need to be the same size? If we can combine them, will a 64x64 sprite on a 32x32 tilemap take 4 tiles, or can we scale it down to one tile? |
0 | Unity DontDestroyOnLoad FindObjectsOfType(GetType()).Length is always returning 1 I'm trying to have an object with the DontDestroyOnLoad property. I want an object with NetworkIdentity to persist across scenes, so I can have a holder script for RPCs. This answer suggests the following code public void Awake() DontDestroyOnLoad(this) if (FindObjectsOfType(GetType()).Length gt 1) Destroy(gameObject) Despite this, I still end up with duplicate objects. FindObjectsOfType(GetType()).Length is always returning 1, and I don't know why, or how to fix it. It makes no difference whether this object is a prefab instance or a simple object in the hierarchy. I have also tried to clone this object in my NetworkManager script, which is automatically persistent, but GameObject.Find("ObjectNameHere(Clone)") is always returning false. However, the above solution seems simpler so I'd prefer to figure out FindObjectsOfType(GetType()).Length. |

0 | Can't refer mesh size after using .BakeMesh() in Unity I can't figure out how to refer to the size of a particular mesh. The mesh is created through .BakeMesh(), then a box collider is added. Unfortunately the box collider has a scale of 1 by 1 by 1, regardless of how big the mesh I'm adding it to seems to be. This doesn't match my understanding of how creating a box collider should work, so I've set up a Debug.Log that outputs the mesh size. Here the plot thickens. The mesh's size just comes back at 0, 0, 0. My attempts at getting the size of the object are as follows objectToMeasure.GetComponent lt Renderer gt ().bounds.size objectToMeasure.GetComponent lt MeshFilter gt ().mesh.bounds.size objectToMeasure.GetComponent lt MeshFilter gt ().sharedMesh.bounds.size Assuming I'm referring to the size of the object in the correct way, this seems like it must be an issue created by baking the object. Do I need to wait a frame (via starting a coroutine) before trying to access the size of the object, or am I referring to the wrong component of the object, or is the BoxCollider setting it's size based on objectToMeasure's scale rather than it's size in the world? I feel sure that objectToMeasure.GetComponent().mesh.bounds.size should be right, since the script I use to bake to the mesh is meshToBake.BakeMesh(meshToMeasure.GetComponent().sharedMesh) I've been driving myself to the edge of sanity for 24 hours with this script not working, so advice is greatly appreciated. |
0 | How to mitigate when applying horizontal force to a rigidbody seems to overpower gravity?

It actually is being applied but it seems as if the force being applied to the body is overriding the force of gravity because as soon as I let go of the movement keys the body suddenly drops. I am not applying any force on the y axis so I'm not sure what exactly is at play here. What is going on here and what can I do to mitigate this behavior? |

I need the 3d poop emoji model in the chest on the right to blink, visible invisible visible, several times This is a 3d gameObject oriented to face the camera, shaded with an unlit material. I need the object to "blink flash" to indicate that the item has been obtained. The object needs to be generated the moment the lid opens (done), stay unchanged until the lid pops all the way up (0.2 seconds), and flash 3 times during the 0.6 seconds the lid is up.

0 | Use an image as mask only where pixels are opaque We are into a game where to build our tile map, we carve on an image with a mask (At first the whole map is an image, and we create holes on it with tiles to create the map and le the background show. It is like substracting instead of adding new tiles in any common tiled based game). We have done this with just a tile that acts as a mask using stencil buffer. The problem comes when we want to mask with tiles where all their pixels are not opaque, for example a slope. The problem is that it applies the mask as if all the pixels in tile where opaque and we want to apply the mask in two differnet ways 1) Keep the pixels of the big image where the mask pixels are opaque 2) Mask the pixels of the big image where the mask pixels are transparent (alpha 0) I have read a lot of info about using stencil and alpha blending but can't make it work. Checking the pipeline order it seems that stencil is applied after the fragment color has been calculated. Is it possible to access the alpha value at stencil stage and write to the stencil as needed to just mask part of the image (tile in my case). Update to add a visual example |

0 | RTS game unit structure I want a way to make a lot of different units without having to program stuff like moveTo and Attack actions more than once The way I see it, there are 2 ways I can do this. A single generic Unit class with flags that specifies what it can can't do (then create instances in a static array and grab them when needed) Abstract unit class with abstract methods for Unit specific actions like (Attack, Harvest, Patrol), which then all need to be implemented in the subclasses, even if the unit can't actually harvest anything. the first way of doing this seems the simplest, but i would end up having a lot of code being unused for the majority of the units. the second way could also work. But if i decide to have two different units that can harvest resources, i'm gonna have the exact same code in two different classes, which doesn't seem like the right way to do it. Is this even the right approach to this problem? In a game like AoE, every unit has, what i presume is, some kind of List of Actions Orders, I would really like to know how to achieve something similar to that, where i can just code each Action Order once, and then give it to all the units that need said Action. If i'm unclear (highly plausible) or you need more information on what exactly i'm looking for, just ask me in a comment. |
0 | Unity Inaccurate rotation if object is rotated on two axis at once I have an object which i want to rotate relative to world space. I have three variables (one for every axis) which store the rotation. By pressing buttons on my controller I add or subtract 90 to these variables (rotX, rotY, rotZ). Then I rotate my Object like this transform.Rotate (rotX delta, rotY delta, rotZ delta, Space.World) As this is called every frame the object would spin forever so i subtract the ammount I've allready rotated afterwards rotX rotX delta rotY rotY delta rotZ rotZ delta This works fine as long as I don't rotate two axis at once. Then the object rotates rotates only partially to the desired position (e.g. 83 if I want to rotate to 90). I can't see what I've done wrong. It actually seems like the moment I start an rotation around an axis all other axis get canceled. But if I monitor the variables they look exactly as they should.

0 | How to write a PBR Unlit Shader in Unity? I have a REALLY specific case here I have an Texture (a webcam), that is used by a shader to pickup a few x,y colors at the cordinates, and renders to a Custom Render Texture, that is later fetched (download pixel color information from GPU to CPU), and I can handle the algorithm from there. The thing is, once I upgraded the project to PBR (Physically Based Rendering), all my Unlit scripts become PINK, and they stopped working. This is a special case because It doesn't need to appear on the screen It acts as a "Compute Shader", but with backward compatibility to old phones It works well without PBR, but once PBR is enabled it becomes pink and stops working It doesn't need to reflect, refract, output pixels or anything to the "Screen", only to my Custom Render Texture so that I can fetch it later. The algorithm doesn't fits on a Graph based programming (it has iterations and etc) Well, I didn't find documentation on how to write custom PBR shaders and here I am. |

0 | Unity3D How to just center a mesh inside a character controller! Hi I have a simple character mesh and it's parented to my character controller invisible capsule object and all the moving code is applied to the parent (if that's relevant), but the point Is I'm trying to line up the mesh to be exactly inside the capsule to make it look like the player is walking ABOVE the ground (pretty normal ...?) So by default the character controller is origined in the center so I move it up by half of it's height to try to get it to line up with the character mesh, which has it's origin below it's feet a little, and this is the result as you can clearly see, his feet slightly go into the ground, I have no idea why this is happen, then should be just above the ground like any other normal feet! Here's the code for setting the capsule up half of it's width, since it starts by lining up the mesh in it's CENTER for some reason Vector3 tempPos player.transform.position tempPos.y (capsuleSize.y 2) chassidSize.y 12 chassid.transform.position player.transform.position player.transform.localPosition tempPos chassid.transform.parent player.transform and here's a picture of the mesh (which is just a blender file, easier for import) As you can see, in the blender file, the origin is slightly below the characters feet, IN THE CENTER, so I don't know why it's not working as planned. Also, you can see in the first picture that he's slightly moved to the center of the controller on the z(?) axis, but I want him to be completely centered in, any idea how to fix this? |

0 | Objects rendering only on editor, but not on build (they get invisible) Everything works fine in the editor, but when I build the game, none of the objects in the scene are rendered, and only the skybox and UI text is visible. But although they aren't appearing, they are working as normally (i.e. these objects' triggers work normally when the determined event occurs, like for example, colliding to a specified object, or in other words, they are invisible). I searched for this issue but didn't found any answer. Could it be my cheap computer's fault (Intel Celeron without an external graphics card)? In editor game mode In buit game I ran both the editor and the built game in the same quality, and also tried to run it in Fastest quality, but no, it made no difference in the built game. Also, there is no object tagged with "Editor only", only one have a custom tag and all the others are "Untagged". And the camera's culling mask is set to "Everything". The result is the same either for web or Windows. Edit OK, I built for Android and the objects render normally. So, I'm not completely sure, but probably it's my PC that can't render the objects, because both building for web plugin and desktop have this disappointing result, but for Android it works perfectly (even the shadows, which wasn't being cast in the editor), so... |

0 | Distributed Rendering in the UDK and Unity At the moment I'm looking at getting a game engine to run in a CAVE environment. So far, during my research I've seen a lot of people being able to get both Unity and the Unreal engine up and running in a CAVE (someone did get CryEngine to work in one, but there is little research data about it). As of yet, I have not cemented my final choice of engine for use in the next stage of my project. I've experience in both, so the learning curve will be gentle on both. And both of the engines offer stereoscopic rendering, either already inbuilt with ReadD (Unreal) or by doing it yourself (Unity). Both can also make use of other input devices as well, such as the kinect or other devices. So again, both engines are still on the table. For the last bit of my preliminary research, I was advised to see if either, or both engines could do distributed rendering. I was advised this, as the final game we make could go into a variety of differently sized CAVEs. The one I have access to is roughly 2.4m x 3m cubed, and have been duly informed that this one is a "baby" compared to others. So, finally onto my question Can either the Unreal Engine, or Unity Engine make it possible for developers to allow distributed rendering? Either through in built devices, or by creating my own plugin script? |

0 | Level Selector with possible future levels? Unity I have a level select screen which is a simple grid layout of my levels. The level data comes from a scriptable object for each level. The problem I have is what is the best method for populating the grid of levels that use the scriptable object and is able to add more levels to the grid layout if let's say I add an asset bundle in the future? My thought was that I use a levelDB which holds a list of all of the scriptable objects. Then when an asset bundle is used then it adds the content to the levelDB. The UI would then just use this levelDB to populate the screen. NOTE I have very little to no knowledge of how asset bundles work and what you can, and cannot do with them. |
0 | Unity Camera Follow target with view port point's offset from center Some additional remarks before I address the issue How Viewports work in Unity Whatever the dimensions of the screen's rect, the viewports coordinates are mapped in normalized coordinates, where 0 represents left and bottom, for x and y respectively, and 1 right and top, for x and y respectively (image below). Follow a Target (Easy implementation for the sake of demonstration) Consider this following simple algorithm to follow a target CameraFollowExample MonoBehaviour public Transform target public bool relativeToTarget public Vector3 followOffset private void LateUpdate() if(target ! null) FollowTarget() private void FollowTarget() transform.position target.position (relativeToTarget ? target.TransformDirection(followOffset) followOffset) transform.Lookat(target) Issue The following works as expected, but the target will always be at the viewport's center ( 0.0, 0.0 ) What I am trying to Achieve This is what I am trying to achieve make camera follow a given target, with an additional offset from the viewport's center. This offset being additional to the following offset applied to the target. So for example, if I define two ranged floats, centerX and centerY respectively, I'd like the camera to be positioned with an additional offset, so the defined offset is at the target. As an example, on the image below, I have centerX and centerY on 0.2, 0.25 respectively, so the target should be at that viewport's point. Having a resulting (partial) script CameraFollowExample MonoBehaviour public Transform target public bool relativeToTarget public Vector3 followOffset Range(0.0f, 1.0f) public float centerX Range(0.0f, 1.0f) public float centerY private void LateUpdate() if(target ! null) FollowTarget() private void FollowTarget() Vector3 destination target.position (relativeToTarget ? target.TransformDirection(followOffset) followOffset) transform.position destination GetCalculatedOffset() transform.Lookat(target) private Vector3 GetCalculatedOffset() interpret the Vector centerX, centerY to return an offset. return (interpretedOffset target.position) What I have already tried Make the camera position to the destination plus an offset of the center centerX, centerY 0.5, 0.5 , the direction is ok, but obviously, the target is not positioned at the expected viewports' point coordinate. Have a global vector that is the custom center point relative to the camera's transform and the nearPlane, and then make an offset between that point and the target, ignoring the z. The camera gets away from the target. What I am not trying to achieve Something like following example (define an additional offset vector, and position the camera with the additional offset) CameraFollowExample MonoBehaviour public Transform target public bool relativeToTarget public Vector3 followOffset public Vector3 additionalOffset private void LateUpdate() if(target ! null) FollowTarget() private void FollowTarget() Vector3 destination target.position (relativeToTarget ? target.TransformDirection(followOffset) followOffset) transform.position destination additionalOffset transform.Lookat(target) I mean, this technically works, since the target won't be at the center of the viewport. But the intention is for the target to be positioned at the defined viewport's point. Any additional information you may need, let me know. Thank you beforehand, and Happy New Year. |

0 | Unity 5 Error with code to make pitch changes based on distance I really need help. It's 2 00 AM here and my brain is half dead so I can't, for the life of me, find out what's wrong with this code anymore. It's supposed to find the distance between the game object to which it's attached (the target), and another game object (the player). Then, depending on the that distance, it should change the pitch of an AudioSource inside a child (in the player). However, the pitch only changes when I'm practically over the gameobject. So, for about 9 10 of the way, nothing changes in the pitch, but when I'm right there the pitch suddenly changes (but not to maximum value of Clamp function). What's going on? I want the pitch to, at first, stay at 0. But soon after you walk some steps in the right direction, the pitch must change gradually (and in a evenly manner), as (player) gets closer to (target). ps. The script is inside a instantiated prefab, that's why I used FindGameObjectWithTag and FindChild.

0 | How can I limit the y rotation of a cinemachine POV camera based on the player's direction? I'm using Unity (2019.4.11.f1, HDRP). My goal is to create a first person POV camera. To this purpose, I tied a Cinemachine (2.7.3) Virtual Camera to the head of a third person player character (one from the Basic Locomotion demo of this asset). The Body of the camera is set to 'Hard Lock to Target', Aim to 'POV', and Recenter Target to 'Follow Target Forward'. This works fine. The camera has a Horizontal Axis Value Range ( to ), that limits the rotation of the camera, but I cannot figure out how to tie this to the rotation of the Follow component (the head of the avatar). When I walk my character around, the camera can only rotate within the set Value Range angle that has it's 0 point in one absolute direction (let's say north), independent of the player's orientation. It seems to use World Orientation, but I don't know and wasn't able to find out where to change that. Does anyone know how I can change this behaviour? |

Is there any way I can bring an Euler representation into some kind of normalized form that allows me to reliably check it against my limits? |
0 | Hierarchical "Select GameObject" Dialog or names with prefixes? I am attempting to connect a series of teleporters with entrances inside a single scene. Once the player touches a teleporter he is moved to another place. I am doing this by simply connecting two game objects as shown in the following screenshot. The particle system in the center of the upper side is used as teleporter, the red line indicates the game object where the player will be transported to. Sadly, this results in an utter mess when attempting to select a new entrance the teleporter should link to. There is no way to guess which entrance corresponds to which side and dice So the tl dr of my problem would be this The name of the object that should be selected is meaningless when isolated. It's the path to the object (or in other terms the name of some parent) that is relevant. I would see three possibilities to solve this, but sadly I haven't gotten around to find out how to do any of them. Switch the "Select GameObject" Dialog to use the same hierarchical view as used in the scene viewer. Is there a hidden option somewhere in Unity that I overlooked? Somehow prefix the names of my entrances programatically. Is there a way to include the path to a certain game object in its name?

0 | Character rotation according to camera causes rapid flipping when game starts When I load my scene, my character rotates 90 and 90 on the X axis very fast about 4 or 5 times, and then he stops at 90 on X axis (lays back down).

0 | Manage vertical levels rendering I've been working on a semi professionnal project for more than one year. The game is in 3D with a TopView camera. In this game, the player will be in very vertical spaces, with lots of ladder and stairs. The actual problem is that I need to show only what is at the actual height of the player. I have made a shader that 'cut' the objects above a given height. The problem is that my mesh are open above this height, and we just see nothing inside. If you have any idea on how to make something to fill an open mesh or any other system that will do the job, i'll be very pleased to read you ) This is what I have This is what I aim to (black above top of walls) |
0 | How to make a PROPER main menu (or any other UI windows modals) in Unity? So, I'm currently learning both about Unity for the first time as well as the 'new' 2D UI system, but I'm having a hard time figuring out how to make windows, modals dialogs, main menus etc. which are not only functioning, but also modular, reusable and written following proper coding standards. Most how to's, blogs, Q amp As or tutorials I find only cover the most basic parts of UI development (e.g. how to drag a button from the toolbar to the scene window in 2 hours). So basically, I'd like to have a main menu which meets those (very common) requirements A button which 'starts' the game (e.g. by simply loading another scene) A button which 'quits' the game, but also opens up a confirmation dialog before A button which opens up an options dialog, which again is composed of multiple parts (audio, video...) and finally, it should be possible to go back to the previous screen using a 'back key button', for example Escape What I started with is a canvas which I called GameMenu. This canvas has several nested canvases, such as MainMenu OptionsMenu OptionsMenuAudioPart OptionsMenuVideoPart CancelMenuModal Then I created a menu script which works as some sort of state machine public class MenuScript MonoBehavior private GameObject currentStateObject private GameObject previousStateObject public void SetState(GameObject newStateObject) if(newStateObject null newStateObject) return if(CurrentStateObject ! null) CurrentStateObject.SetActive(false) previousStateObject currentStateObject CurrentStateObject newStateObject CurrentStateObject.SetActive(true) Every button has now an event trigger attached which calls the SetState(...) method on MenuScript. However, I've got the following problems How do I pass multiple parameters to methods invoked by event triggers? As soon as I add another parameter to SetState(...), for example bool isModal false to tell the method that it shouldn't disable the previous state, then it disappears from the event trigger action selection menu. How to I register key press events within the event triggers? It's easy by script (Input.GetKey(...) etc.), but I didn't find one on the event type selection. How do I make e.g. event triggers conditionally? So that certain events cannot be called when certain states are active? I know I can solve all those problems within the script and make a fully functional main menu which does exactly what I want, but then... I cannot use it for something else I don't use the new Unity UI system, which makes me wonder what's the purpose of it I got to reference all involed game objects (the canvases, buttons etc.) in script, which makes it not really 'extendable' anymore as this means for every changed requirement, I have to alter the script (e.g. a new state, menu, button etc) The main goal in the end is a script which I can use for all kinds of UIs without writing the same logic over and over again just because it's another scene, game state etc. |
0 | How To Place Object On Ground Within Radius? I'm using Unity and I'm building an object placement system where you'll be able to position objects around the player. I'd like to place objects flush with the ground, parallel to world up, even on slopes, so I'll use a raycast for that. How would I limit the distance to maxDistance? I tried using ScreenPointToRay but the max distance on the raycast makes the movement of the object stop if the raycast doesn't hit. As an example, If I'm looking down in front of me, the object i'm controlling should be at that position. However, if I'm looking straight forward into Infinity, the object should only ever be maxDistance away. If I rotate, the object should follow smoothly. Thanks! edit here is a video of what I have now, but as you can see, the object gets stuck if the raycast doesn't hit anything due to the maxDistance. It doesn't get stuck if i use Infinity for the ray distance, but then the object doesn't respect max distance like I want it to. https streamable.com bacij8 Code snippet https gist.github.com zackperdue 270e9574bed4a937bef791fb41512291 |

0 | OnMouseUp not working in unity A common problem in Unity my OnMouseUpAsButton() is not being called, and I do not understand why. I have attached box collider 2d (though its size is set up during runtime, but by the time I click on it it has proper size and covers the whole button). My object is an UI element, created from prefab during runtime. Here you can see its inspector info Code using UnityEngine using System.Collections public class button controller MonoBehaviour void OnMouseUpAsButton() Debug.Log("Clicked event button") switch(click action) case action.NONE action none() break I tried going through other threads where people had similar problems but nothing seems to work. Any ideas what might be happening? EDIT I found out that if I add a new button , directly from the inspector to the canvas, whose collider is within the canvas all other buttons start working. Interestingly I cannot put this new button anywhere, it has to be at least a bit within the canvas |
0 | Programmatically generated mesh vertex colors not showing up in Unity? I'm sorry if this is an obvious thing to solve but I just can't figure it out...did I miss something...I've generated a mesh and during vertices generation I've also set its colors (and colors32 just in case) by reading those values from a ply file, and afterwards I've added a number of vertex color shaders but none of them will show the vertex point colors in play mode, it's either solid black or just like I added no material to the mesh (which I've tried doing manually in play mode too).

UPDATE I added this to the Update if (radius gt 0) var newPos (transform.position Turret.transform.position).normalized radius newPos Turret.transform.position transform.position newPos The problem is now that some times when the radius the distance from the Turret is small for example 20 or less some times the transform is getting right above the turret not sure why. I want it to rotate around the turret at the fixed set distance(radius) but not to be above the turret. Can't figure out why sometimes it's moving right above the turret then after some time it's getting back to the set distance. |

0 | Why do prefabs speed up loading? I have a scene with a massive terrain. It took a long time to load (approximately 60 seconds) when I pressed play. I am in the editor. I prefabbed it.

0 | Behavior Trees or GOAP for Rimworld like game? I am currently making a Rimworld like game. For now, it is identical in appearance, how the map works and how the pawns (colonists) are supposed to function. Core world generation logic and A pathfinding is done, so my next step is to implement AI. The question for a game such as Rimworld (since the original author of the game never mentioned what sort of technology he used), is it preferable to use Behavior Trees or Goal Oriented Action Planning AI methods? I use Unity and have found assets for both of the technologies GOAP Behavior Trees I am expecting large map sizes, anywhere from 200x200 to 400x400, and an AI agent might have to take a lot of things into consideration (his environment, the position of his allies and enemies, possibly nearby items and structures). I am leaning towards GOAP because even though it seems harder to implement at first, it seems easier to maintain later, because the agents figure out stuff on their own based on the information they are given, so I won't have to hard code every single action or pattern (please correct me if this is wrong.) I also have no experience with either of the technologies so this might be something to take into account, but I am willing to learn. Any suggestions, comments or ideas are much appreciated and I'm open for discussion. |

But cameraPosition has to be relative because its location depends on the player's location, so I can't figure out how else to write it. |
