I think you mean blitting, not blipping. In my limited graphics experience decision-making on whether you should double-buffer is still case-by-case. How many of your objects are changing at once? Even though it's only a few, are all of them changing? If so some of the caching may not be worth it, redrawing each time will be more efficient. If they aren't changing (or only one is) you can sometimes take advantage of the bitmap caching for the ones that aren't changing and turn it off for the ones that are. You'll just need to experiment...

All of the examples I have read so far involve many objects that don't change a lot and combining them into a single large bitmap. My question to those of you that know anything on these topics is as follows: Is this technique also appropriate for a only few objects that scale and transform in size, color, blend modes and alpha? -trey -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!
