upgrade screen

Unity Engine

I want to figure out a way to open and close different gui objects in a script by clicking in game. I cant find it in the manual so any help would be appreciated.

There are several ways:
Use an if:
if(doInventory) {
GUI.Button(…
}

use a switch and enums or ints:
switch(guimode) {
case GUIMode.Inventory:
…
case GUIMode.Spells:
…
}

or use delegates , which is nicely outlined in this thread:
