Fighting Game - Key combo

hey,

Well… I’m currently making this “street fighter” style game… where you have characters attack and block etc… However… the problem i’ve run into is the “multiple” key detection actionscript…

So far… I can only get those one key presses to work… but i want to do combos… like if i were to press UP+DOWN+Z or something in sequence in a limited amount of time… say… 1 second… and then it’ll execute an animation…

Anyone know how i should do this?

thanks.
