GUITexture from script?

How to create GUITexture from script (c#)?

public class GHUD : MonoBehaviour {
private GUITexture gtxt = new GUITexture();

void Awake() {

DebugConsole.Log("object: "+gtxt );

In console: "object: UnityEngine.GUITexture", so it's looks like it is created...

gtxt.transform.position = new Vector3(0,0);
gtxt.texture = someImage;

when I try to access transform or texture Unity throws NullReferenceException
what's wrong ???

 

Not sure why texture is failing but you should be defining a proper Vector3 (0,0,0).


Also, I'm moving this to the GUI section in 3... 2... 1...

 

Vector3 has nothing to do with that error.... (btw, in docs there is Vector3 (x : float, y : float) constructor )

Just for test I have created New Project , created Empty GameObject and attached the following script

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class NewBehaviourScript : MonoBehaviour {
6.     public GUITexture myText;
7.  
8.     // Use this for initialization
9.     void Start () {
10.         myText = new GUITexture();
11.         print("object:"+myText);
12.         print("pos:"+myText.transform.position);
13.     }
14.    
15.     // Update is called once per frame
16.     void Update () {
17.    
18.     }
19. }
20.  

access to myText.transform.position throws:
NullReferenceException
NewBehaviourScript.Start () (at Assets/NewBehaviourScript.cs:11)

is it a bug in the Unity ??

 

GUITexture is only a component, not a game object.

So what you would do is add a new game object to the world and instead use AddComponent to add the guitexture properly to the game object in question.
then you will also have the possibility to access the other game objects components that are present commonly like transform etc

Generally you would never create Components through new, always through AddComponent

 

Thanks you! I had that thought , but when you look into documentation and see that GUITexture has all these Inherited Variables you get the idea that it should contain all transforms,etc....quite a mess in docs or in the class tree...

a bit later...

It is working like that, but you have to set scale to:
gtxt.transform.localScale = new Vector3( 0.0F ,0.0F ,1.0F );

 

<facepalm> Sorry for missing that obvious point in my first reply...

 

//...example want to create cube and add ur component with GUITexture you should follow this....
void CreateCube(){
cube=GameObject.CreatePrimitive(PrimitiveType.Cube);
cube.AddComponent<GUITexture>();
}
