Hey guys, why i have this error? In c#?

GUI.color.a = LogoAlpha;

error CS1612: Cannot modify a value type return value of `UnityEngine.GUI.color’. Consider storing the value in a temporary variable

You cant set the individual component “a” in C#. You will have to do something like this

GUI.color = new Color(r, g, b, LogoAlpha);

Cause you can not modify directly a unique struct item, cause these itens are “read only”.
The structs gives you only a “Get” method to these itens, but not a “Set” method.

You need to assign a object, even if you need to set only a unique item.

Exemple:

GUI.color.a = LogoAlpha; //this will give you the error

You need to do:

Gui.color = new Color(Gui.color.r, Gui.color.g, Gui.color.b, LogoAlpha);

Hope this help and sorry for my poor english,
