Does anyone know any tips for speeding up ActionScript, particularly with regard to script loops and array access?

It seems very slow… eg. trying to move more than 20 small sprites around the screen forces the frame rate below about 30 fps.

do you have a single clip telling them to move, or are they moving themselves? If each clip moves itself through it’s own “onClipEvent” it tends to make the movie run faster.
