Why in the dialogue system it's showing in the conversation only 2 sentences and not the whole 3 sentences? The first script the manager is attached to new empty gameobject I want the conversation to start automatic when running the game so i'm calling the method TriggerDialogue in the manager using System.Collections using System.Collections.Generic using UnityEngine public class DialogueManager MonoBehaviour public DialogueTrigger dialoguetrigger private Queue lt string gt sentences Use this for initialization void Start () sentences new Queue lt string gt () dialoguetrigger.TriggerDialogue() DisplayNextSentence() public void StartDialogue(Dialogue dialogue) Debug.Log("Starting conversation with " dialogue.name) sentences.Clear() foreach(string sentence in dialogue.sentences) sentences.Enqueue(sentence) DisplayNextSentence() public void DisplayNextSentence() if (sentences.Count 0) EndDialogue() return string sentence sentences.Dequeue() Debug.Log(sentence) void EndDialogue() Debug.Log("End of conversation.") Next the DialogueTrigger using System.Collections using System.Collections.Generic using UnityEngine public class DialogueTrigger MonoBehaviour public Dialogue dialogue public void TriggerDialogue() FindObjectOfType lt DialogueManager gt ().StartDialogue(dialogue) Last the Dialogue using System.Collections using System.Collections.Generic using UnityEngine System.Serializable public class Dialogue public string name TextArea(3, 10) public string sentences In the editor I filled the all 3 TextAreas each one with a sentence. Hello world Hi everyone I have woke up When running the game it's showing only to the Hi everyone it's not showing the I have woke up. And it also not showing the "End of conversation." in the log.

Overcoming float limitations for planet sized worlds in Unity As far as I know, going further than 1M units from the world origin in Unity is hardly possible due to floating point precision issues. Making a world more than 1M units in radius would require either using double vars for coordinates or utilizing some space division technique to divide a massive scene into hierarchical chunks with the smallest of them being around 10 000 units, i.e. each world space position would be expressed by the chunk hierarchy the object's in and a bunch of float vars representing its local position (and possibly rotation and scaling) inside the last chunk. Either way, doing this would require implementing a completly new coordinate system, so I'd like to know whether or not that is possible in Unity, and if so, how may I make it work with existing Unity systems like physics and so on. P.S I can't just move the world into origin as the player moves since I want to have things going on simultaneously around the planet. Thanks!

How is entering cover animation done for cover system? I am trying to create a cover system for my 3rd person shooter game in Unity. My implementation is a basic one On Player enter Trigger Player move to preset cover position Player play Enter Cover animation (eg dash to cover) This is fine without root motion enabled, when it is enabled (so the movements look natural), instead of dash amp stop behind the cover, the Player will dash and stuck himself inside the cover (due to root motion). So I am curious, what is a good way to do the animation for cover system?

Draw GUI.Button on certain position on a scrollable background Problem is in a 2D game I have a large background around 2 screens wide. And on there I got 4 buttons placed on top of background all over complete width. Now when I swipe of move my mouse around I scripted that the camera will move with it. So for the GUI.Buttons (Unity4.5) to stick on their place I used a variable drawX drawX Camera.main.transform.position.x 100 The 100 is for calculating it to pixels. I then add this to my buttons when drawing. scaleX Screen.width 1920f scaleY Screen.height 1200f if (GUI.Button(new Rect((500 drawX) scaleX, 700 scaleY, 325 scaleX, 425 scaleY), "")) Now the problem is that under 1920x1200 my target resolution everything works exactly pixel perfect. But when changing the resolution or aspect ratio to something else the drawX increases to much or not enough so the buttons don't move on the same pace as they did in the 1920x1200 version. Somebody got the solution for me?

How I randomise a list of audio clips in Unity and remove it from the list once the clip is finished? I have 4 audio clips. When I play a press a certain button in Unity, the data is sent to MAX MSP and the audio is played. I created a list a signals (As shown below in the code). What I want is that, the signal list is randomised. The user presses a button to listen to the audio (which works fine). Once the clip is finished the user presses Next Trial button. Once the Next Trial is pressed. The previous clip is removed from the list. Once all the clips are finished. A message is displayed in the Debug.Log( quot All trials finished quot ). I have the following problems One of the audio clips is repeated again. It appears that the audio clips are not removed from the list. How do I write the audioclip index to a csv file?

Flatten transform hierarchy at build time Nested hierarchies cause a performance overhead when they include moving objects. Every time a GameObject moves, altering its transform, we need to let every game system that might care about this know. Rendering, physics, and every parent and child of the GameObject needs to be informed of this movement in order to match. As the scope of a game increases, and the number of game objects skyrockets, just the overhead of sending out all these messages can become a performance problem. However, nested hierarchies are useful in organising a scene and keeping logical groups of gameobjects separate. What options exist to save performance whilst keeping the hierarchy? Is there any pre existing solution to flatten a hierarchy when building only?

How to draw a 2D cross section of a 3D object? I am creating a game where I only want the user to see the 2D intersection of a plane with a 3D object. The goal of the game is to move this plane to a certain position and rotation, which gives a certain 2D shape. Here is a link to a website which illustrates the 2D slices of a 3D object. How do I approach this if I only want the player to see the slice. Just to be clear, the solution does not necessarily have to be in 3D, since the ui for the player is going to be 2D anyway

Unity Editor Scene View does not match built executable I'm trying to make my game resolution independent. I'm using Unity's 4.6 UI, and I've got custom resolutions defined at 1280 x 720, 1600 x 900, and 1920 x 1080. In editor, if I swap between any of these resolutions, the observed scene doesn't change. It looks like this I then build an executable (set to only allow 16x9 resolutions), and run this scene. On 1280 x 720 (as selected from the resolution dialog), I get this While on 1920 x 1080 (as selected from the resolution dialog), I get this Which matches the editor view. (Ignore the character sprites those are in worldspace on a separate camera and aren't relevant to this question). What is it about the executable that causes lower resolutions to be "zoomed in" like this, even if that lower resolution is the Reference Resolution for the Canvas Scaler?

Small health bar above entity is drawn differently when the entity is rotated differently Here is a simple positioning code for my health bar transform.position Camera.main.WorldToScreenPoint(target.position 0.2f target.up) Here is the prefab HealthBar is middle center anchored, and 0.5, 0.5 pivoted, Background and Fill are stretched and 0.5, 0.5 pivoted, but background is Left, Right, Top, Bottom 1 positioned. Here is how it should look (all images are zoomed in) And here is a video about the entity rotating around https i.imgur.com EOzFEvt.mp4 2 example rotations, in which the health bar is drawn incorrectly (see the border of the bar) Why? Edit Another interesting artifact If I'm moving the camera up, the healthbars are offsetted up a bit, and if I start moving down, it's instantly offsetted down, with left and right the same, etc. As soon as I stop, it's at the correct position, but as soon as I start moving, it becomes offsetted to the direction I'm moving. See gif https i.imgur.com K8mwzTW.mp4 Fix for this Place it in LateUpdate.

Character bobs when moving Whenever I try to move a character in unity, the character kind of, like, bobs around when walking. Is there any way to remedy this? I have tried the trick of putting the inputs into update and the outputs into fixedupdate, if that's any consolation.

When serializing a class, can its fields take their defaults from the Unity editor? Can I have a custom serialized class whereby I set a value in the editor and that value persists into runtime, as happens with serialized monobehaviour fields? Currently it sets itself to 0 or a default hard coded from within the class. I noticed that using a struct actually works but using a struct breaks the events used in my actual use case (included below). Example code public class Class1 MonoBehaviour this variable can be set in the editor and persist into run time SerializeField private float testVar1 this variable can not SerializeField private Class2 class2 private void Start() class2 new Class2() Serializable public class Class2 SerializeField private float testVar2 My use case Serializable public class EditorFloat SerializeField public float value public EventProperty lt float gt eventProperty public EditorFloat(EventProperty lt float gt eventProperty) this.eventProperty eventProperty Object.FindObjectOfType lt CentralParams gt ().OnUiChange Update this.eventProperty.OnChanged UpdateEditor public void Update() eventProperty.Value value public void UpdateEditor(float valueFromEventProperty) value valueFromEventProperty Thanks!

Storing Type Game Data Within A Unity 3D Game Using An Offline Flatfile Database I've read several documents on how to manage game type data Would it be better to use XML JSON Text or a database to store game content? How to choose how to store data? Im developing an offline RPG game in Unity3D. I've made online games before, but with online we had an edge for the database. For the online game we used a MySQL database each time the player loaded the game, they would download the database (JSON setup) and we would parse it on the client side and it would be good to go. However for an offline RPG I don't have the luxury of storing my game type data online. To be clear when I say type data I mean things like Monster tables Item tables Ability tables etc What I liked about the MySQL database was that it was tabluar and I could edit rows and columns easily and not need to create hundreds of classes subclasses to manage the type data. My question is how can I mimic the MySQL database in Unity3D? I considered using an excel file but I feel that would be so easy for the user to hack. Just change the excel data and boom, you've hacked the game. Is there a way I can create an offline (secure ish) flatfile database that will let me avoid having to create tons of type data class files to manage all my game data?

How to play sound in WebGL build in Unity? I have a project that works fine when I build for windows, but doesn't work when I switch platform to WebGL. The SerializeField AudioClip variables in the inspector are all 'missing', even after I check 'override for WebGL' convert to AAC. And when I try to link any audio file to an AudioClip within a WebGL build in the inspector, it doesn't seem to work. How do I get sound to play within WebGL? To recreate the problem Switch platform to WebGL. Create a new Script in any recent unity version, then add a SerializeField AudioClip x. Put that script on a new gameobject and try to link an audio asset to it (default import settings, however don't forget to check 'override for WebGL' to AAC, otherwise you will get compiler errors when you switch platform).

Getting player cube to move left or right in relation to camera based on camera's rotation Right now I'm trying to make the player cube move left, right, up and down in relation to the camera's rotation and position. I figured what I could do is create an empty game object, make the main camera the parent, and then get the vector pointing from the camera's child to another game object that follows the cube's exact position, and that would give me the direction the cube should roll towards. I have my example in profile view, but in 3D view the camera should be facing the cube with the cube at the center. So I have the following line of code code Vector3 forwardVector (position1.transform.position position2.transform.position).normalized If you look at the image on the right hand side, I Debug.GetLine'd the resulting vector from the cube's position and ended up with a vector pointing down. In theory though, it should be pushing off to the right hand side. Here's the rest of the code Vector3 perpendicularVector Vector3.Cross (Vector3.up, resultant).normalized if (Input.GetKey (KeyCode.UpArrow)) cube.rigidbody.AddForce ( forwardVector moveSpeed) if (Input.GetKey(KeyCode.DownArrow)) cube.rigidbody.AddForce ( forwardVector moveSpeed) if (Input.GetKey (KeyCode.LeftArrow)) cube.rigidbody.AddForce ( perpendicularVector moveSpeed) if (Input.GetKey (KeyCode.RightArrow)) cube.rigidbody.AddForce ( perpendicularVector moveSpeed) As a result, when I press the up arrow key, I end up with the cube flying upwards toward the sky, and the down key brings it back down towards the plane, but my intention is for the vector to move along the XZ plane. Also, with this line of code, I was hoping to get the line perpendicular to my intended vector and Vector3.up, but I naturally get wonky results from that. Vector3 perpendicularVector Vector3.Cross (Vector3.up, resultant).normalized If there's an easier method to achieving my goals, that's fine, but it would be nice too to figure out why the vector is pointing down instead of to the right. It's also might be worth noting that the camera already successfully rotates around the player cube.

What's a viable way to get public properties from child objects? I have a GameObject (RoomOrganizer in the picture below) with a "RoomManager" script, and one or more child objects, each with a 'HasParallelagram' component attached, likeso I've also got the following in the aforementioned "RoomManager" void Awake () Rect tempRect HasParallelogram tempsc foreach (Transform child in transform) try tempsc child.GetComponent lt HasParallelogram gt () tempRect tempsc.myRect blockedZoneList.Add(new Parallelogram(tempRect)) Debug.Log(tempRect.ToString()) catch( System.NullReferenceException) Debug.Log("Null Reference Caught") HasParallelgram is an empty script with a public Rect set in the editor and nothing else. Unfortunately, attempting to assign tempRect tempsc.myRect causes a null pointer at run time. I've done some more digging, and the reason for the null pointer is relatively simple the RoomManager script gets woken ("Awake") before the HasParallelagram script gets instantiated ("Start"). It's an issue of timing I need to wait until all objects have been instantiated before calling the RoomManager. Does Unity support a means of doing that? What's the proper way to get a child's component?

How can I move an object over linerenderer lines positions? I have 4 cubes the first 3 cubes connected with two lines one of the lines is curved. The fourth cube I want to move over the lines. The lines is built using linerenderer and in the linerenderer there are 397 positions. I created a small script that move an object over the positions. I checked and I have in the array 397 positions and the loop get to 397 but the object (Cube (3)) never moving all the positions only some. Or maybe the positions I get are not the same in the linerenderer ? This screenshot show some of the positions in the linerenderer this is the positions I want the object to move on Why the object is not moving over all the positions , only on some ? And this is the script I created that should move it using System.Collections using System.Collections.Generic using UnityEngine public class MoveOnCurvedLine MonoBehaviour public LineRenderer lineRenderer public GameObject objectToMove public float speed private Vector3 positions new Vector3 397 private Vector3 pos private int index 0 Start is called before the first frame update void Start() pos GetLinePointsInWorldSpace() Vector3 GetLinePointsInWorldSpace() Get the positions which are shown in the inspector var numberOfPositions lineRenderer.GetPositions(positions) Iterate through all points, and transform them to world space for (var i 0 i lt numberOfPositions i 1) positions i transform.TransformPoint(positions i ) the points returned are in world space return positions Update is called once per frame void Update() if(index lt pos.Length 1) objectToMove.transform.position pos index Time.deltaTime speed index Now I checked using a breakpoint the first position in the linerender at index 0 is X 30.57, Y 6.467235, Z 4.98 But in my script in the pos array I see that in index 0 the position is X 30.6, Y 6.5, Z 5.0 And the result is that the object that move Cube(3) is moving only some of the way and also it's not exactly on the line Why the object is not moving over all the positions , only on some ? Something is wrong in my script with getting the right positions from the linerenderer and maybe also the loop and the move is wrong. I can't figure out ho to do it.

How does Unity's QualitySettings.masterTextureLimit work? I'm trying to get to the bottom of how masterTextureLimit works, but my results have been inconsistent so far. I created a massive sprite (8192x8192), and I'd like to resize it at runtime to save performance. The idea is to start with large sprites and then resize based on the monitor's resolution. Here's what happens at different settings Texture import size 8192, masterTextureLimit 0, mipmaps off 2ms Texture import size 8192, masterTextureLimit 0, mipmaps on 1.5ms Texture import size 8192, masterTextureLimit 1, mipmaps on 1.5ms Texture import size 4096, masterTextureLimit 0, mipmaps off 0.9ms Texture import size 4096, masterTextureLimit 0, mipmaps on 0.9ms Texture import size 4096, masterTextureLimit 1, mipmaps on 0.83ms Looking at these results, I have a couple of questions If masterTextureLimit is supposed to halve the texture resolution, why did it not affect performance while setting texture size to 4096 did? Why did turning mipmaps on improve performance at 8192 texture size but not at 4096? My camera is orthographic, and it's only 1 unit away from the sprite.

Unity3D Button Slicing Problem I'm having trouble getting my button to appear correctly, as you can see in the image below, the right and top sides are stretched out and not displaying properly. I cannot figure out if this is a problem with the image itself or something wrong in the way I'm setting up the button. Here are the settings in the inspector window Here is the original image UPDATE So everything looked fine when I just opened up Unity, so I tried to figure out what I did last time for it to make this switch. It happens when I build and export the scene to my Android device.

(Unity) Shortest way to instantiate an object and obtain it script Normally I use ScriptName script ((GameObject)Instantiate( Resources.Load("Prefab"), new Vector3(x, y, z), Quaternion.identity )).GetComponent lt ScriptName gt () It is a little too long and too much of brackets, so I wondering if there is any other way to get instantiated object's script without break it in two statements.

Unity RTS Single Selection Problem I am trying to build an RTS game and I have managed to form a way to select a unit using Raycast and the tag system. I made it so that if the object the ray falls onto is of tag "TankUnit" Make so and so variable true and allow it to move to another place. However, Units of the same tag even when not selected also move. How do I fix this problem? The script is bound to each unit. using System.Collections using System.Collections.Generic using UnityEngine using UnityEngine.AI public class UnitController MonoBehaviour bool clicked false public float speed 10f public float rotationSpeed 10f public LayerMask groundLayer public NavMeshAgent playerAgent Update is called once per frame void Update() if (Input.GetMouseButton(0)) Debug.Log("Clicked") FindClickPos() if (Input.GetMouseButton(1) amp amp clicked true) Debug.Log("I clicked right mouse") Ray ray Camera.main.ScreenPointToRay(Input.mousePosition) RaycastHit hit if (Physics.Raycast(ray, out hit)) MoveTo(hit) private void FindClickPos() RaycastHit hitInfo new RaycastHit() bool hit Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), out hitInfo) if (hit true) Debug.Log("I hit " hitInfo.collider.name) if (hitInfo.collider.tag "TankUnit") Debug.Log("I hit" hitInfo.collider.tag "!") clicked true else Debug.Log("I didnt hit a unit ") clicked false else Debug.Log("I didnt hit anything...") clicked false void MoveTo(RaycastHit hit) Debug.Log("Position " hit.point) playerAgent.SetDestination(hit.point)

GameObject not exiting through leftScreen I'm trying to wraparound game object so that, it exits through right screen and enters through left and vice versa. The code snippet below is what I'm working on. Vector3 Pos mainCam.WorldToScreenPoint(transform.position) Vector3 LS mainCam.ScreenToWorldPoint(new Vector3( 1, 0f, 0f)) Vector3 RS mainCam.ScreenToWorldPoint(new Vector3(1, 0f, 0f)) if (Pos.x gt Screen.width) transform.position new Vector3(LS.x, transform.position.y, transform.position.z) if (Pos.x lt 0) transform.position new Vector3(RS.x, transform.position.y, transform.position.z) So far, exit through right and re enter through left works, but the gameObject does not exit through the left screen, there seems to be a barrier preventing it, or maybe my parameters for the second if statement are wrong.

Unwanted rotations with transform.RotateAround I didn't tough i would have issues with this, but unfortunatly I did. I have a Character (which is more a pile of cube) with a body, a empty GameObject for each leg attached to the body with a join and 2 cubes for leg too. The body and the two empty gameobject are child of a Empty gamebject. The 2 cube that represent leg are both child of one of the empty gameObject. What I want to achieve is to rotate the leg around the position of its empty parent by doing this if(Input.GetKey("l")) l leg.transform.RotateAround(l leg.transform.parent.transform.position, new Vector3(1,0,0), 75 Time.deltaTime) unfortunatly, I only want it to rotate on x, but all of the axis are changing, which lead to unwanted rotation. Now, I know rotations aren't independant like translations, but I don't know how to fix this. If possible, i'd prefer to rotate locked joint via script but I have now idea how, I haven't seen anything about it when I looked up 2

Manually creating an instance of object derived from MonoBehaviour I'm currently "newing" an instance of a class I have that derives from MonoBehaviour and store it in a list. The value of this instance is "null" however, even though it has all the fields of my derived class in it so it passes as null in null checks. After more reading it seems it's a bad idea to manually new up an instance of an object that derives from MonoBehaviour. The class is an Actor class. I have a situation where enemy actors are 3D models in my scene and so I want them to derive from MonoBehaviour, but the player actors don't have world representations really. I just have a picture of them in the corner. Similar to Legend of Grimrock. I wanted the 1 Actor class since the data they need is all the same and I wanted to avoid having 2 classes for no seemingly reason other than not newing up a MonoBehaviour derived class. What are my options with this requirement when my player actors don't need MonoBehaviour but my enemy actors do but they all need to have the same properties?

How to write a custom shader in Unity 3D that lights up a specific pixel or group of pixel? I'm making a FPS game in Unity, and I want the environment to light up as the player is shooting on his environment. The map would be entirely put in darkness at the beginning, but as the player shoots the environment, it would be rendered with its "real texture". So say I have a tree. First it is entirely black or greyish, but if I shoot somewhere, I would see some green. To accomplish this, I'm using a raycast to get the impact point and so I can access any renderer of the point that the player is shooting on. I guess the next step would be to write a custom shader to light the exact pixel that is shot. Do you have any idea how I could write this shader or another way of doing this effect? Regards

translation and rotating at the same time and waiting before animation? I am having difficulties here. I want to move my character with the buttons and I want the character to rotate wherever he is going. Also I want to play an animation when there is no keys pressed. I am able to do that but I want the animation to play after 10 seconds of no key being pressed, and only once. Than after a movement that resets and again after 10 seconds of no key the animation plays. (The animation works but it happens right after I stop pressing a key and continuously.)

What's the proper way to use static objects and singletons in Unity? I have a GameObject in Unity, which I've attached this script to, in order to make it function as a Static Singleton using UnityEngine using System.Collections public class SceneStatics MonoBehaviour private static SceneStatics instance public static SceneStatics Instance get if (instance null) instance new GameObject ("SceneStatics").AddComponent lt SceneStatics gt () DontDestroyOnLoad(instance) return instance public void OnApplicationQuit () instance null I have two other scripts that I'd like to be able to access from scene to scene. What's the proper way to do that? Do I attach my Inventory and Room scripts to the same game object as the SceneStatics? If so, how do I access them? Can I go from SceneStatics.Instance to one of the other scripts directly via GetComponent? Alternatively, what happens if I add two child gameObjects (each containing one of the other scripts) to the SceneStatics? Or is the intended use that I simply make any other static items I need properties of the SceneStatics class? (I.e., add in a Public static Inventory and Public static Room attributes)?

How do I ensure consistent behaviour when using Unity's Collider2Ds for triggers and collisions? I am experiencing inconsistent behavior using Unity's 2D Physics engine and their Collider2Ds to detect collisions and triggers on my projectiles. I will classify it into two problems. The first is that occasionally the projectile will pass through walls objects it should collide with. The second is that occasionally the projectile will pass through enemies that it should hit without triggering. I will try to elaborate in detail below. A projectile is organized into a container Projectile GO and two children GO a PhysicsColliders GO and a HitBoxColliders GO. The PhysicsCollidersGO job is to hold the colliders that define the solid regions of the projectile using Collider2D components. It's GO is on a Projectile layer which is set to collide with other solid layers such as the ones my walls are on. Walls are static colliders. The HitBoxCollidersGO job is to define the a HitBox area. It's GO is on a HitBox layer and also uses Collider2D components that are set to be triggers. A HitScript on the GO listens for OnEnterTrigger. Projectiles are set in motion by setting the velocity of the RigidBody once upon firing. Here is a visual of the structure ProjectileGO PhysicsCollidersGO HitBoxCollidersGO Here are descriptions of the GameObjects and their components ProjectileGO RigidBody2D Component (collisionDetectionMode is set to Continious) PhysicsCollidersGO (Layer is set to Projectile) BoxCollider2D Component HitBoxCollidersGO (Layer is set to HitBox) BoxCollider2D Component (IsTrigger is set) HitScript Component Problem 1. Projectiles will sometimes not collide with walls solid objects etc... Problem 2. Projectiles will sometimes not trigger a hit. What could be causing these inconsistencies? How can ensure that collisions and triggers will consistently behave correctly?

Collider does not call callback functions I have a script that will create new GameObjects and will place it where the mouse is placed on the terrain. Now I need to have a check for collision on other already placed GameObjects on the field. I check different tutorials and documentation and cannot find a way to do this in code. My code looks like objectToPlace (GameObject)AssetDatabase.LoadAssetAtPath("Assets Game 3D Models Buildings " objectName ".fbx", typeof(GameObject)) objectToPlace.SetActive(true) objectToPlace.transform.localScale new Vector3(1, 1, 1) objectToPlace Instantiate(objectToPlace) objectToPlace.transform.Rotate(Vector3.right 90) BoxCollider collider (BoxCollider)objectToPlace.AddComponent(typeof(BoxCollider)) collider.isTrigger true In the same class as the above code I have OnTriggerEnter function. But that function is not called. How can I link the Collider to that function in Unity 5.6? I also tried using the Physics.CheckBox for checking if my new create gameObject does not collide to any other object. But without any succes.

Encapsulating parameterised prefabs I'm currently using the following general pattern for most of my configurable components (i.e. MonoBehaviours) public class MyComponent MonoBehaviour Configurable fields SerializeField private bool someParameter SerializeField private int anotherParameter Fake constructor to act as a replacement for GameObject.AddComponent with additional parameters. public static MyComponent AddTo(GameObject gameObject, bool someParameter, int anotherParameter) var myComponent gameObject.AddComponent lt MyComponent gt () myComponent.someParameter someParameter myComponent.anotherParameter anotherParameter return myComponent Public properties and other methods ... This works around the lack of constructors for MonoBehaviours but still encapsulates the parameters in such a way, that they can only be set at the time the object is created, or through the Inspector (which is effectively the same thing once the game is built). Unfortunately, this approach doesn't help once I want to use my component inside a prefab. When I instantiate the prefab, the component has already been created, and I can no longer touch those parameters. And as far as my google fu can tell, there's no way to pass parameters into prefab instantiation (much like there isn't a way to pass a parameter into AddComponent). It seems like everyone just instantiates their prefabs and then fiddles with some public properties to configure them. So the question is, is there any way to set things up, such that I can configure some fields on my prefabs, but without exposing them publicly and breaking encapsulation? (I realise that I could add a similar static "factory" method which instantiates a specific prefab and then configures the component inside that prefab, but a) this means adding one such method for each prefab and b) it breaks down once I want to configure multiple components within the same prefab.)

I want camera to be positioned on the player also x axis should move continuosly by .05f in unity 2d I am creating an 2d platformer and I am newbie to Unity any help will be highly appreciated. I want the camera to be positioned on the player and also the X axis should move continuously by .05f. And if player is not moving or stuck somewhere and if player is behind camera player (because X axis is automatically moving by .05f) then player should die. Is it doable? I am using Cinemachine and any script logic will be appreciated.

Set the start orientation of the gyroscope to initial phone orientation I am making a mobile VR project in Unity, and I have a 360 degree video that starts playing where I can look around using a VR headset.

2 cameras that each player sees through a different one Im very new to Networking in Unity 5. Im trying to bring the finished basis for my 2 player, 1 vs 1, turn based game I made for local multiplayer (both players on same computer) to an online matchmaking system. In the game currently (for local), there are 3 cameras. 2 centered on separate canvases for selecting attacks for each player. that once p1 chooses his attacks and presses continue, the camera is deactivated and the 2nd camera for p2's attacks is activated. Once p2 presses to continue the 2nd cam is also deactivated and the 3rd cam is put on, this camera is set on the battle arena and plays out in turns the moves picked by the 2 players through a turn determining system. What I want to do for the online is have both canvas cameras activated at the same time and each player to be assigned to a different camera. So is there a good way i should do this? NetworkView on one of the cams? Hope I explained the premise enough P

How to use Input.GetAxis("Mouse X Y") to rotate the camera? I want to make a first person camera that rotates with the mouse. I looked at the Input.GetAxis Scripting API page and found a sample code, which I have included at the bottom of my post. Upon trying it out, I realized that although it has the same basic functionality I hoped it would have, it does not keep the camera parallel to the xz plane, particularly when moving the mouse in circles. After a while the camera would be at an odd angle, and the player would be completely discombobulated! Is there a quick fix to this code that would restrict the camera movement somehow, or is there a better way to rotate the camera? using UnityEngine using System.Collections public class ExampleClass MonoBehaviour public float horizontalSpeed 2.0F public float verticalSpeed 2.0F void Update() float h horizontalSpeed Input.GetAxis("Mouse X") float v verticalSpeed Input.GetAxis("Mouse Y") transform.Rotate(v, h, 0)

How can I rig an object to animate from two different orientations? As an example Say you're animating a skateboard. The board has a nose and a tail. Normally, the nose points forward and the tail points backward. Now say you have two animations idle and trick. The idle is animated with the nose pointing forward. The trick, however involves the board rotating 180 , ending with the nose pointing backward, functionally swapping the nose and tail. Now, if you were to blend the trick animation back into idle, the blend would rotate the board back around so the nose points forward, which would not be the intended behavior. The intended behavior would be for the animator to somehow know that the tail is now the forward facing orientation and animate as if the tail were the nose. I'm competent but no expert with rigging animation and I've been racking my brain trying to come up with either a way to cleverly rig the object to somehow work as intended or to be able to modify the animations procedurally in code or something, but I haven't been able to figure it out. This seems like a problem that must come up somewhat frequently with game animation, but I haven't been able to find any specific resources. I'm using Blender and Unity. Edit To be clear, I'm not talking about root motion or the animating object's position rotation in the world, just the orientation of the bones being animated.

How to make the camera follow the mouse in first or third person camera I currently I have a game made of a few small scripts, the PlayerController, PlayerStats, and CameraChange (each below). My question is how do I get the camera to follow the mouse movement? I want the player to be able to switch between each camera and look around with the mouse.

Unity Custom Inspector Platform dependent property section I want to make a custom inspector for one of my scripts that builds UI elements at runtime. This requires small changes to the default values depending on what platform I'm targeting. How do I add something that is similar to the graphics settings where there is a default option but each platform is able to override the default setting for a platform specific value? I'm looking for the same kind of thing that Unity has for the player settings (Edit Project Settings Player). This allows you to set the details for each one but you can override them for each platform if they need to be different.

How do I dynamically use the rect tool in Unity2D? The rect tool in Unity2D (I honestly do not remember if it is present in Unity3D) allows you to scale down scale up an object in just one direction (what it does is it simultaneously increases decreases the height of an object in transform.scale and transform.position. I was trying to scale down an object while keeping its position the same using this code (P.S. I took the first four lines of code from here The Best Way To Generate a Random Float in C ) float range (double)float.MaxValue (double)float.MinValue float sample scaleRand.NextDouble() float scaled (sample range) float.MinValue float f (float)scaled if (f gt 0.6f) f 0.6f gameObject.localScale new Vector2(gameObject.lossyScale.x, (gameObject.lossyScale.y f)) However, this code does not work. So, how can I recreate the effect of using the rect tool in Unity Editor using C ?

Press and hold camera movement with mouse in new Input System? I am transitioning to the new movement system and am having trouble figuring out how to move the camera when a mouse button is pressed and held. Here's how I did it before private void Update() Get the position of the mouse when a middle click occurs if (Input.GetMouseButtonDown(2)) dragOrigin cam.ScreenToWorldPoint(Input.mousePosition) If the MMB is still held down, calculate the distance and move the camera if (Input.GetMouseButton(2)) Vector3 difference dragOrigin cam.ScreenToWorldPoint(Input.mousePosition) cam.transform.position difference I have tried doing something similar in the new input system but it doesn't work public void OnMMB(InputAction.CallbackContext context) if (context.phase ! InputActionPhase.Started) Get the position of the mouse when a middle click occurs dragOrigin cam.ScreenToWorldPoint(Mouse.current.position.ReadValue()) else If the MMB is still held down, calculate the distance and move the camera Vector2 newPosition cam.ScreenToWorldPoint(Mouse.current.position.ReadValue()) Vector3 difference dragOrigin newPosition cam.transform.position difference Here is how I set this up inside the Input editor The Action Type of the action is Button.

Creating a delay by using Invoke Is it possible to delay the effects of a script that is attached to a game object? I have 2 characters in a scene, both receiving live motion capture data, so they are both animated identically. I have rotated one by 180 degrees and placed it in front of the other one, to create the impression that they are copying mirroring each other. Each has several scripts attached to them, of course... Now, I would like to be able to delay one character a bit (e.g. 1 sec) to make it look more realistic, as if one character is observing the other character and then copying its exact movements. Is it possible to do this by somehow using the Invoke method on the other character's Update perhaps? Or any other possibilities to achieve what I described? EDIT I used a buffering mechanism, as suggested by all the helpful comments and answers, instead of delaying, because delaying would have resulted in the same network data being used, except after a delay, but I needed the same old data being used to animate a second character to create the impression of a delayed copying... private Queue lt Vector3 gt posQueue private Queue lt Quaternion gt rotQueue int delayedFrames 30 void Start() posQueue new Queue lt Vector3 gt () rotQueue new Queue lt Quaternion gt () void Update() Vector3 latestPositions Quaternion latestOrientations if (mvnActors.getLatestPose(actorID 1, out latestPositions, out latestOrientations)) posQueue.Enqueue(latestPositions) rotQueue.Enqueue(latestOrientations) if ((posQueue.Count gt delayedFrames) amp amp (rotQueue.Count gt delayedFrames)) Vector3 delayedPos posQueue.Dequeue() Quaternion delayedRot rotQueue.Dequeue() updateMvnActor(currentPose, delayedPos, delayedRot) updateModel(currentPose, targetModel)

Flare (particle system) showing weird semi transparent rectangles instead of smoke when there's fog in the scene I'm making an FPS game with some fog in the scene. I've added a flare particle system (from the standard assets' prefabs) but it looks like it has some weird collision with the fog. Whenever the fog is enabled I get these weird rectangles on top of the flare like in this screenshot I've noticed that when I turn off the fog they disappear, also I've noticed that when I turn off the Emission part of the particle system the rectangles disappear, but of course, also most of the wanted effect is gone.

How do I make a rainbow hue shift over time on text? What I'm trying to do is make a Text object have an animation that allows for the hue of the color to go all the way up and loop back around, so it creates a cool rainbow thing. I've looked on google for a solution but the solution I found only worked in older versions of Unity, which were used back in 2015. What I found Any help would be appreciated!

Problem with Factory Method Pattern when I try to create a Weapon MonoBehaviour I'm learning about Design Patterns using Unity and I'm not sure about how to solve the following problem with the Factory Method Pattern I want to read a XML file and using the Factory Method Pattern to create a Component (a Weapon) to add it to a GameObject which will be cointained on a Pool Manager, but Weapon "Is A" MonoBehaviour and for that reason It can't be instantiated using a "machineGun new MachineGun() " public abstract class WeaponFactoryMethod protected string fileName "weapons.xml" public abstract Weapon CreateWeapon() public class MachineGunFactoryMethod WeaponFactoryMethod public override Weapon CreateWeapon() string filePath Path.Combine(Application.streamingAssetsPath, fileName) Weapon machineGun null XmlReader xmlReader new XmlTextReader(filePath) if (xmlReader.ReadToDescendant("Weapons")) if (xmlReader.ReadToDescendant("Weapon")) do I CAN'T DO THIS machineGun new MachineGun() machineGun.ReadXml(xmlReader) while (xmlReader.ReadToNextSibling("Weapon")) else Debug.LogError("There aren't definition for Weapon") else Debug.LogError("There aren't definition for any Weapon") return machineGun public abstract class Weapon MonoBehaviour, IXmlSerializable public float AttackRange get set Every weapons Shoots in a different way public abstract void Shoot() Serialization public XmlSchema GetSchema() return null public void ReadXml(XmlReader reader) XmlReader childReader reader.ReadSubtree() while (childReader.Read()) switch (childReader.Name) case "AttackRange" childReader.Read() AttackRange childReader.ReadContentAsInt() break public void WriteXml(XmlWriter writer) public class MachineGun Weapon public override void Shot() Raycasting.. At the end I want something like GameObject (player) Component (A Weapon script with the data from the xml) Should I just create a GameObject (player) and do an "AddComponent lt MachineGun " and later copy the info from the xml file instead using the Factory Method Pattern?? Is there a better way?? Any suggestions, corrections or advice will be very grateful. I'm sorry by my English.

Aspect ratios for sprites in Unity3d I'm using Unity3D version 5.0. I'm wondering what the best way to deal with changing resolutions in Unity is. In Swift I can just use the x2 x3 in order for it to pick the correct sprite for it to use. Is there a similar mechanism in Unity? Thanks

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. Thank you in advance and have a amazing day!

How can I send commands to only certain clients? I am building a multiplayer game server with Unity. In the game there are players moving around the map. Now, because this map is quite large compared to the number of players, I was thinking to have the server send each clients' position only when they are nearby, and then slow the rate down when they are far away. At first I was using the convenient SyncVar to do sync everyone's position, until I discovered its shortcomings, that is there is no conditional way to either sync or not a certain value. I came out with this player synchronization class so far (I removed all optimizations for simplicity) public class PlayerSyncPositionConditional NetworkBehaviour Vector3 lastPos void FixedUpdate () TransmitPosition() ClientCallback void TransmitPosition () CmdProvidePositionToServer(transform.position) Command void CmdProvidePositionToServer (Vector3 pos) transform.position pos Now, what this code does is nothing more than sending its position to the server when I am looking at the dedicated server instance, each players' position is correct. Also, as expected, each client will not receive any updates. From my research, I found that instead of SyncVar, I can use Server and ClientRpc to dispatch commands from the server to all clients, so this Server public void MoveTo() RpcMoveTo(transform.position) ClientRPC void RpcMoveTo(Vector3 newPosition) transform.position newPosition this will run in all clients would move all clients to the transform current position whenever needed. Now, the problem is that those commands, apparently affect every client, while I only want to affect ones that are near each other. I know how to have the server issue the MoveTo at any rate I want, setup more than one interval, etc. but I don't know how to have it send only to certain clients at a single time. I am not asking for the code itself, but I am getting really confused with all these client server architecture concepts, which class does what, etc. so any heads up will be greatly appreciated.

How to play an animation backwards in Unity? I know this question has been asked before but it all involves using the Animation(?) component, so that is no longer any good in Unity 5.3.1f1, I explain a bit more later. I'm trying to simply get an animation to play backwards. On the object that I want to have an animation play backwards on, I have an animator. private Animator anim ... anim GetComponent lt Animator gt () If I do animator.speed 1.0f It tells me Animator.speed can only be negative when Animator recorder is enabled. Animator.recorderMode ! AnimatorRecorderMode.Offline So I try putting on an Animation component on the game object, and making the clip the animation. Every time I do anything with the Animation component in script, it tells me the component must be marked as Legacy. That is no good, because when I tried making it Legacy it caused multiple problems including not being recognized by the Animator. Also GetRef errors. The entire Animation component seems like it's treated as legacy now or is just broken. So I decided well maybe I could just try to get the animation to play backwards in the animator and having the animator record it, and then using that backwards recorded animation in the actual game. I cannot figure out how to this, even if I click record in the Animation view anim.recorderMode ! AnimatorRecorderMode.Record. I don't know what to do. All I want to do is play the same animation backwards without having to copy and paste an animation in the Project and moving all of the keys around so that they are reversed. Please help. Unity's animation system seems so convoluted in script.

Unity, Cannot See Items on the Scene I am new to unity. I have created an asset by using Blender and managed to put it in the scene. But somehow now I can only see one item at a scene. For example I can only see camera when I clicked "Main camera" at the Hierarchy toolbar. When I clicked the asset, the camera is hidden from the scene along with lighting etc. This is difficult for me since I need to put my asset in front of the camera. Where can I toggle back the views for everything in the scene?

How to display custom UnityEvents in the editor? I recently stumbled upon the UnityEngine.Events.UnityEvent class, and it seemed pretty cool so I started using it in a project.

Other stuff ... But now it doesn't show up in the editor, making it harder to wire up my subscribers. Is there a way to make unity events with extra arguments show up in the Unity editor?

With a Texture Atlas that has 128x128 tiles, how can I use that in Unity3D? So I've got a working texture atlas that has tiles fitting 128x128. However, I can't quite figure out how to use them. I know it's probably got something to do with TileRenderer.material.SetTextureScale(" MainTex", new Vector2(0.25f, 0.25f)) TileRenderer.material.SetTextureOffset(" MainTex", new Vector2(0 0.25f,0)) but I'm not sure where to take it from there. Can anyone offer some advice? The size of the image is 1024x128 if that helps, which I think it might.

How to make an expanding radial search in Unity? I am currently working on a City Builder Game and I often come across the problem of having to decide wich location to use. Examples The citizen has a job and needs a home. There are several buildings with open slots. The citizen is at a positon and is hungry. There are several restaurants on the map. How can I choose the right building to go to? I don't really wan't to check the distance for each, because there could potentially be hundreds of buildings and that decision problem occurs quite often. I also don't care for the optimal solution, any nearby result is fine. Currently all buildings register them self in a LinkedList. When searching for something I'd start at the beginning and the first occurrence that was 'good enough' would be returned. Citizen now drive across the map for something that was right next to them if the one far away was built earlier in the game. Any suggestions?

How to seamlessly handle multiple procedural 2D levels in Unity3D? I have a dungeon generating algorithm, but I would like to generate X levels, which are all connected somehow. I have a few approaches, but all of them has problems and questions, and I wonder how i.e. Diablo II handles them so seamlessly. 1. Approach Upon leaving a level, generate the next one on the fly. This would be the easiest, but would result in a relatively long loading screen everytime the player enters a new level. So generating the levels should be at the beginning of a new game, thus the next level will just have to be loaded, which is much faster. In theory not even a loading screen is necessary. 2. Approach Generate every level at the beginning of a new game and store them. Okay, now levels just have to be loaded, which could be done under half a second. No loading screen is necessary, maybe just a fade out fade in. How do I store them? Make custom files (i.e. scriptable objects) for them, or is there a simpler way? 3. Approach Generate and load every level at the beginning. Zero loading time, because everything is already generated and loaded into the tilemap. But how do I guarantee that levels don't collide, and the player can't see level Y from level X if there are lots of levels? And wouldn't it affect the performance? Because everything is loaded all the time. Yes, renderers, rigidbodies, scripts, etc can be turned off, improving the performance a lot... but still... this seems wrong. What is the best way to solve this problem?

Trouble with Inventory System and Item References I'm currently trying to get a simple inventory system to work but I'm having a lot of trouble. This isn't the exact code I have, but it's a shorter version that I'm pretty sure would function the same public struct ItemSlot public Item item public ItemSlot(Item item) this.item item public class Item MonoBehaviour public string itemName public class Accessory Item public class Inventory MonoBehaviour public ItemSlot itemSlots new ItemSlot 1 public void AddItem(ItemSlot slot) itemSlots 0 slot public class Player MonoBehaviour public Inventory inventory private void Update() if (Input.GetKeyDown(KeyCode.E)) Ray ray Camera.main.ScreenPointToRay(Input.mousePosition) RaycastHit hitInfo if (Physics.Raycast(ray, out hitInfo, 20)) GameObject target hitInfo.collider.gameObject inventory.AddItem(new ItemSlot(target.GetComponent lt Item gt ())) Destroy(target) if (Input.GetKeyDown(KeyCode.G)) print(inventory.itemSlots 0 .item) For a bit more prefacing I have a capsule object with the Player script on it, an empty with the Inventory script on it, which is then attached to the Player script (I'm not sure if I want to make the inventory a scriptable object which is why I've done this), and then lastly I have a cube object with the Accessory script on it. So, when I press E and pick up the item it gets added into the player's inventory and then destroyed from the scene. Then, when I press G to display that item in the inventory the console just says null. Not Null, which is what an actual null would show up as, but the string "null". If I use visual studio's debugger and have a look at what the accessory's base is, it also says null, but for some reason if I then try and print the accessory's name then that works fine, even though that variable is defined in the Item class. If I instead do this in the Inventory class public void AddItem(ItemSlot slot) ItemSlot 0 slot print(ItemSlot 0 .item) It works fine and prints Item (Accessory) in the console. Even if I print it right after I destroy target in the Player class, that also prints Item (Accessory), so I have no idea why it doesn't work on the next block of code. Sorry this is so long and maybe an easy fix, but I'm lost. Edit I think everything should be fixed now.

How to clip what is outside scroll view when using a custom UI element? I have created a custom UI element (that use CanvasRenderer). Here is code Mesh mesh new Mesh() Rect drawArea GetComponent lt RectTransform gt ().rect using (VertexHelper helper new VertexHelper()) helper.AddVert(new Vector3(drawArea.xMin, drawArea.yMin), Color.white, Vector2.zero) helper.AddVert(new Vector3(drawArea.xMin, drawArea.yMax), Color.white, Vector2.zero) helper.AddVert(new Vector3(drawArea.xMax, drawArea.yMax), Color.white, Vector2.zero) helper.AddVert(new Vector3(drawArea.xMax, drawArea.yMin), Color.white, Vector2.zero) helper.AddTriangle(0, 1, 2) helper.AddTriangle(2, 3, 0) helper.FillMesh(mesh) var canvas GetComponent lt CanvasRenderer gt () canvas.SetMesh(mesh) canvas.SetMaterial(Material, null) It creates a simple rectangle that is same size as rect transform. It works great. However if I put this inside a scroll view, everything that is outside scroll area viewport is rendered (while it should be clipped). The scrolling works as it should (rectangle get scrolled by changing position when scrollbar is used). I have tried to call canvas.EnableRectClipping(...) but without success.

Unity problems with OnTriggerStay and Input.GetKeyDown Background information Some weeks ago, I start by creating my own platform game. You control a character, that can collect logs and should hold all the campfires on in the game. When the user has collect more then one log, the player have to use this log to hold the fire on. So you should walk to the campfire and should press E to give the log to the fire. Problem What the problem momently is, is that when I press the E key, it will fired the input more then one time. This is because I use a OnTriggerStay2D function, to check every second if my Player is collide with the campfire object. Do some search on the internet, results in people with the same problem. So one of the solutions was to create an bool and set it to true on OnTriggerEnter2D. But this isn't working for me. The same problem as before will occur. Is there another solution to fix this conflict. When the user press the button, it should be fired ones. Below script is linked to the campfire object. Also tried it with if(Input.GetKeyDown(KeyCode.E)) isTrigger true and the same for GetKeyUp, but then isTrigger false My current working code public Animator anim public int campfireStatus bool inTrigger false Use this for initialization void Start () anim GetComponent lt Animator gt () Update is called once per frame void Update () anim.SetInteger("Intensity", campfireStatus) void OnTriggerEnter2D(Collider2D other) inTrigger true void OnTriggerExit2D(Collider2D other) inTrigger false void OnTriggerStay2D(Collider2D other) If player comes in contact with gameObject if (other.gameObject.tag "Player") print ("player") if(Input.GetKeyDown(KeyCode.E)) print ("E Pressed") if (WoodBehaviour.count gt 0) campfireStatus So when the Player is collide with the campfire object AND the player pressed the E key AND you have more then one logs (this counter will be set in the WoodBehaviour script, that is linked to the player object ) than it should increase the campfireStatus with plus one. The problem is, that the if statements will fired more then one times when pressing the E key.

Managing shared dll correctly in Unity I'm developing a dll that is to be used in two Unity projects. I've read that the way to reference a dll is to drag it into a 'plugins' folder so that it is added to the Unity project's dependencies, as their is no "add reference" available for this project in Visual Studio. But doing that the Unity project does not take into account that the dll evolves (as it is still in development). What I'd like (if possible) is to set up an automatic way so that the Unity projects update their dependencies when the shared dll is updated. I've try the reimport option (right click on the dll in Unity) but it seems that it is not working. What is the best way to manage this situation?

Issues using NetworkServer.Spawn with Unity and Mirror Networking I am using Mirror to handle the networking aspect When I spawn an object on the network, I Instantiate it on the server and then use NetworkServer.Spawn to notify all clients to spawn the object. However, when this object is eventually spawned on the client side, it seems to be spawned at the wrong position for a few seconds and then corrected itself and move to the correct position as is reflected by the server. Is there something I am not doing? Is this normal? Also I noticed if I changed the Network Sync Mode to 0, then it will only spawn in the wrong spot for a split second. using System.Collections using System.Collections.Generic using UnityEngine using Mirror public class EnemySpawner NetworkBehaviour public uint theId public int maxNumEnemies public int spawnDelay public GameObject enemyToSpawn float curSpawnTime BoxCollider2D boxColl Start is called before the first frame update public override void OnStartServer() curSpawnTime spawnDelay boxColl GetComponent lt BoxCollider2D gt () void Start() if (!isServer) return theId netId Update is called once per frame void Update() if (!isServer) return if (transform.childCount lt maxNumEnemies amp amp curSpawnTime lt 0.0f) Vector2 spawnPoint new Vector2(Random.Range(boxColl.bounds.min.x, boxColl.bounds.max.x),Random.Range(boxColl.bounds.min.y, boxColl.bounds.max.y)) curSpawnTime spawnDelay SpawnEnemies(spawnPoint,netId) else curSpawnTime Time.deltaTime Server void SpawnEnemies(Vector2 spawnPoint, uint theId) GameObject gobj Instantiate(enemyToSpawn, new Vector2(60.7f,1.3f), Quaternion.identity) gobj.GetComponent lt EnemyController gt ().parentNetId netId NetworkServer.Spawn(gobj) The way I've organized things, in the hierarchy I have Enemies Area1 Spider(Clone) Spider(Clone) Area1 has the EnemySpawner script. The spider is registered a spawnable prefab. Both Area1 and the Spider have a NetworkIdentity with no boxes checked. Additionally, the Spider has a NetworkTransform and NetworkAnimator.

Drawing circles at the background of a 3D scene and updating their size So, here is what I am trying to do in Unity 5 (using C ). I want to draw a a 2D circle at the background of a 3D scene and apply a texture image to fill it. Just like it would be if the circle was in the GUI, but now being always behind everything else instead of always in front (think of a moon in the sky of a piloting game, or a distant planet in a space game, etc). What would be the fastest way to draw such a circle and, of course, update its radius depending on the camera distance? Of course, I don't want to use a sphere, I want to learn how to that with a simple circle that gets bigger or smaller depending on the distance of the viewer.
