I've written a small animation using 18 PICT resources (slices taken from a Javascript rollover) in a FOR/NEXT loop that's choppy regardless of timing. I figure using GWorlds could smooth things out and make it look as smooth as in the original Java. Here are my questions: 1). Does anyone have a simple GWorlds shell routine they'd be willing to share? Ideally it would simply show how to copy a PICT resource to GWorlds and then call it back again into a PICTURE FIELD. The simpler the better. 2). Any GWorld tips/traps I should be aware of? 3). Has pixel manipulation in FB^3 changed with the shift to registers and PPC? (I can't find anything about it in the new FB^3 reference.) 4). Would it be easier to convert the rollover to a QuickTime movie, and then call that? If so, does anyone have some simple code demonstrating use of QuickTime movies in FB? (I really prefer the PICT resources, but would like to better understand QT's interaction with FB.) Ken
