    How to do a translation after a rotation?

    The question isn't totally as dumb as it sounds...After rotating the Stage, I want to be able to pan across it using a normal axis. How do I correct for this?

    For instance, if I rotate 20 degrees...translating 200 pixels up will translate me 200 pixels up if the North direction was slanted 20 degrees...I want to go 200 degrees north in the usual axis.

    _x += 200sin(20), _y -= 200cos(20)
    who is this? a word of friendly advice: FFS stop using AS2

    Thanks...I figured that about 10 minutes before you posted by sketching it out, though it took awhile...That seems to work.
