Some Little Questions

ok im currently working on an MMORPG and I have to say it ain’t easy lol.

Kind i am sort of after is like MapleStory if you want to see what that is just go to YouTube and search lol… MapleStory o.O.

I have everything working towards characters and monsters like

-AI that goes everywhere for flying and up slopes and across grounds for non-flying
-Character moves (shooting, jumping, etc.)
-backrounds made
-Monsters follow and attack you
-random damages that show

but there is one thing i can not seem to get working…

I want a camera to move with the User Interface and that the platforms are able to be jumped on atm i can’t see to land on them, lol… If possible please make a .fla showing some code of how to get on platforms and with gravity falling, get back off.

Any Ideas?:!:
