Fading a GUI.DrawTexture?

Archived Forums Questions & Answers

I am trying to use a white texture that I draw full screen as a transition effect between different menus that I am using. The issue arises because I am using many GUI elements, and I need this white texture to be on top of everything else when it fades. I have tried a few different methods, but since I can’t control a textures alpha directly when it is drawn as a GUI element, I can’t seem to figure out a solution.

Any ideas?

you can change the alpha component by setting GUI.color before drawing the texture.

e.g

 Color c = GUI.color;
 Color old = c;
 c.a = fadeAlpha;
 GUI.color = c;
 GUI.DrawTexture(....);
 GUI.color = old;

You can control the alpha of the texture by setting GUI.color:

void OnGUI()
{
	var c = Color.white;
	c.a = 0.4f;
	GUI.color = c;
	GUI.DrawTexture(new Rect(20,20,400,300), texture);
}

You can control the order by setting the script execution order of your OnGUI script for the top level.

Or by setting the GUI.depth
