Graphics.DrawTexture side effect

Hi... I have this simple script method

Code (csharp):

1. void OnGUI()
2. {
3.     // Paint the full bar.
4.     Graphics.DrawTexture(
5.         fullTarget,
6.         textureLifeBar,
7.         fullBar,
8.         0, 0, 0, 0);
9. }

This works as expected: Paints a portion of the texture like a life bar. However is also re-painting it below for what it seems to be the third of its original size. Really don't know why I'm getting this second bar (attached image shows this undesired result, which I'm pretty sure is my bad somehow).

Every variable is set once in the Star() method, there is nothing inside Update() or FixedUpdate(), no other scripts change this variables... in fact there are no other scripts running.

Thanks for any help.

 

You are using Graphics.DrawTexture, try using GUI.DrawTexture and see what happens.

 

Thank you for your tip... I used Graphics.DrawTexture because was very easy to draw a clipped texture with it. Finally, as you suggested, I ended using GUI.DrawTexture which required tripple the lines and more preparation to do the same.

If someone knows how to fix the issue I'll be back to Graphics.DrawTexture.

 

Don't know if this will help:

"If you want to draw a texture from inside of OnGUI code, you should only do that from EventType.Repaint events. It's probably better to use GUI.DrawTexture for GUI code."

Thanks for your reply. I've read that before, but I don't understand what are or how to code Repaint events.

 

Just a guess:

Code (csharp):

1.  
2. void OnGUI()
3. {
4.    if (Event.current.type == EventType.Repaint)
5.    {
6.      // Paint the full bar.
7.      Graphics.DrawTexture(
8.         fullTarget,
9.         textureLifeBar,
10.         fullBar,
11.         0, 0, 0, 0);
12.    }
13. }
14.  
15.
