Title: NGUI Camera targetTexture to GUI.DrawTexture
Post by: jkaris on November 07, 2012, 12:54:05 AM
Hi,

I'm attempting to draw the view of the camera to the GUI and I can't get it working.

This is basically what I have tried:

  1. using UnityEngine;
  2. using System.Collections;
  3.  
  4. public class s_guiCam : MonoBehaviour
  5. {
  6.         RenderTexture rt;
  7.         public Camera guiCamera;
  8.        
  9.         void Start ()
  10.         {
  11.                 rt = new RenderTexture (Screen.width, Screen.height, 24);              
  12.                 guiCamera.targetTexture = rt;
  13.         }
  14.        
  15.         void OnGUI ()
  16.         {
  17.                 GUI.depth = -5001;
  18.                 GUI.DrawTexture (new Rect (40, 0f, (float)Screen.width, (float)Screen.height), rt);
  19.         }
  20. }
  21.  


Can someone let me know if this is even possible or what I'm missing.

Much thanks,
JK.

OnGUI is Unity's GUI. It's not NGUI. Get rid of the OnGUI function and use a UITexture to display the render texture you're rendering the camera into.

Hi ArenMook,

Thanks for the speedy response - I've only had NGUI for a couple days and I'm not exactly sure how to do what you said.  Could you please explain a bit further how to achieve this?  Sorry for the noob-ness...

J.

Add a Simple Texture (aka UITexture). Set uiTexture.mainTexture = rt;

Hi ArenMook,

I have attempted the following:

I have a game object in the Hierarchy named "NGUIObject" - I have attached a component UITexture to it.

I have created a UI Root (2D) and it simply contains 1 single label.

I have attached the following script to "NGUIObject"

  1. using UnityEngine;
  2. using System.Collections;
  3.  
  4. public class CameraToTexture : MonoBehaviour {
  5.        
  6.         public Camera NGUICamera;
  7.        
  8.         RenderTexture rt;
  9.         UITexture uiTexture;
  10.        
  11.         void Start () {
  12.                
  13.                 uiTexture = gameObject.GetComponent<UITexture>();
  14.                
  15.                 rt = new RenderTexture (Screen.width, Screen.height, 24);
  16.                 NGUICamera.targetTexture = rt;
  17.                
  18.                 uiTexture.mainTexture = rt;
  19.         }
  20. }
  21.  

When I run it, I can see in the Inspector for "NGUIObject" that the texture is being assigned to the Texture in UITexture - but I am seeing nothing on the screen.

Am I missing a step somewhere?

Thanks again,
J.

... NGUI camera shouldn't have a render texture. That's what draws your UI. You should assign the render texture to your camera that you want to do the rendering -- like a camera set to view your character's model, for example.
