was wondering if it would be posible to give the player a choice in which charactor to play as (Diablo style) like create a first room with the charactors in view they click on a hotspot over the chatacters and then when they start the game they are that character....
You ... just asked this. (http://www.adventuregamestudio.co.uk/yabb/index.php?topic=23528.0) (OK, not exactly, but the same command applies.)
And you answered your own question:
Quotecreate a first room with the charactors in view they click on a hotspot over the chatacters
That, or a GUI, along with what strazer told you is all you need to know.
