[paragui-users] blitting

[Keith]

hi, i've been working on an animation engine for some time now but have only
started trying to tweek things recently. i'm currently haveing an issuse
with what seems to be drawing/blitting too often. in short, i use eventidle
to determine if it's time to draw the next frame, when it is, i switch the
frame and call update, which calls the eventBlit. i've placed a time check
message in the eventIdle, perfect, only off my 1 or 2 ms here and there. the
blit is called and just as fine, 1-2 ms off, however, the blit gets called
at least 10-20 more times which then makes the animations appear to fall
behind audio. so i guess my question is when and why is the blit called so
often? i thought that it's only called on the update once. or is there
something else that calls the blit, and is there a way to stop that? if
anyone wants, i can put the code online and you can play with it, but it
ties in with ogg vorbis audio to compile it. i suppose i could cut that out
and you'd just get animation, but then you probably wouldn't notice the
problem... like happened to me, until the audio is there.
