I have two questions with regard to fading in out / changing the alpha value over time: 1.) FadeIn/Out a GUITexture: I would like to fade in / out a GUITexture on a certain event. So I have found the JS FadeIn-Script (http://www.unifycommunity.com/wiki/index.php?title=FadeIn) and would like to modify it a bit and make it C#. Now in C# when I type guiElement.color = Color.red; I get the following error: 'UnityEngine.GUIElement' does not contain a definition for 'color' --> What would be the C# equivalent for this?? 2.) Change color/alpha of a Plane: In the Start()-function I set the color of the plane to which the script is applied: renderer.material.color = new Color(1,0,0,a); The color is set fine (I have tried with several), though the alpha value has no impact (plane is always opaque) --> Why??
1) .color is a member of GUIText and GUITexture, but not of GUIElement. Try guiTexture.color instead. 2) The plane must have a shader that supports transparency. You're probably using the default Diffuse shader, which doesn't.
1.) I get the same errors for GUIText as well as GUITexture. Furthermore "guiElement.color = Color.red" does work in JavaScript --> so it should work in C# also. Any ideas?
Well, no, it shouldn't...that uses dynamic typing, which C# doesn't have. guiElement is obsolete anyway (as I believe the warning tells you). --Eric
