when you goto a room, and edit a 'when player enters room' script, you can type all your stuff out, then it appears in green for the script (well most of it). then you press ok etc. until you reach the main screen of QDK again, where all your rooms/objects are. Then if you go back to the same room, and goto the script tab, all that script has gone, but if you click 'Edit Script', its all there in the menu, and when you press ok it appears again. if that didnt make sense, test it out, you'll get what i mean then lol
