Using an Enum for GUI.Toggle?
Hi!
Say this is my enum info:
public enum Difficulty
{
Easy,
Normal,
Hard
}
public Difficulty currentDifficulty;
How do I go about making 3 GUI.toggles out of this enum (where only one can be "currentDifficulty"/active)?
Something like this:

You use a SelectionGrid. Have the names taken from the Enum by Difficulty.GetNames(). Because Enums are convertable to ints and vice versa, the folllowing should work:
currentDifficulty = (Difficulty)GUILayout.SelectionGrid((int)currentDifficulty, Difficulty.GetNames(typeof(Difficulty)), 3, toggleStyle);
EDIT: the correct line of code.
Thanks for the quick response!
I got this (sort of) working:
currentDifficulty = GUILayout.SelectionGrid((int)currentDifficulty, Difficulty.GetNames(typeof(Difficulty)), 3, toggleStyle);
But I get this error:
Cannot implicitly convert type `int' to `$$anonymous$$ain$$anonymous$$enuScript.Difficulty'. An explicit conversion exists (are you missing a cast?)
Do you know how I can convert it correctly? (I am using C# by the way)
You need to typecast it by putting (Difficulty) in front of the int that throws the error. $$anonymous$$y guess for the appropriate place is
currentDifficulty = (Difficulty)GUILayout.SelectionGrid((int)currentDifficulty, Difficulty.GetNames(typeof(Difficulty)), 3, toggleStyle);
