How do i make it so, if my player ( hero) presses two keys at the same time, theres a combo, lets say he pressed y and u at the same time, the player does arial kick, how do i do it? player instance: hero http://www.newgrounds.com/dump/item/2613b8b8765a8e59d46e1262705738cf
He pretty much wants it so that if two keys are released at the same time an action will play out, I'm not going to type out the exact code, but it would look something like this.
} if(Key.isDown(key number)){ gotoAndStop(frame number){ }else{ if(Key.isDown(key number)){ if(crouch=true{ gotoAndStop(frame number){ (can use a 0 or 1 if you like number better)
Like I said that's not the exact code and I'm not in the editing window for actionscript(which helps me a lot) so there are probably a couple of errors in that code.
Btw: Like Darkroot said I have a feeling you've just been copying and pasting. Good games never come from copy and pasting, you can tell from just playing the game if the creator did that. Just a tip.
