you dont need to draw action areas fot the action areas (lol) just use inactive/active image for them. nothing else. The "real" button is configured the other way around: no images but a defined area.
Thats it! Thanks.
Now I set the active images of all 3 "action area buttons", if I enter the action area of the "real button" and I set the inactive images of all 3 "action area buttons", if I leave the action area of the "real button". And only 1 of the 3 "action area buttons" is visible at the same time (conditions).
And the conditions are set automaticaly by object name. If the object name ends with "_N" then you see the nose in the interface. If the object name ends with "_E" then you see an ear in the interface. Otherwise the mouth is active.
