anyway the first thing i'l ltell you is :
those stage things you'Re making there .....
stop them
Stages dont work like this in gamemaker
you built the stuff piece by piece from objects in Gamemakers Level builder
anyway I forgot a lot about gamemaker in anyway I havnt worked with it for ages
but there are 2 chars in this gmk file : Ashura and knux the codes of both have self explanating entrys which tell you what piece of code does what most of that stuff is stil lfrom Gamerdee's engine which I've used as base
you can get the engine below it includes the needed objects and such the menu is easy to understand too
so if one of yo uguys here is interested in building the stuff further :
http://www.sendspace.com/file/02lhzm
this is the engine
if you got further questions just pm me
also check all the bojects in there to see what they work like this engine basically explains itself as I've allready said earlier
