- Is it ok to use Setscreen to do double buffered animation (i.e., draw
- on one buffer while the other is being displayed and switch. I don't
- know if I've used the right term for this). By that I mean, does it
- work on all nominally ST compatible computers, including those with
- video cards? (Of course, I'd also pay attention to what GEM tells me
- when I start up so that I reserve enough memory for each screen.)
-
- Also, a little while back, someone (Dave Baggett??) was talking about
- how one should sync one's game to update the screen every n vblanks
- (where n depends on how much is happening in the program), which will
- among other things, insure that the game plays at the same speed
- across variants of ST-type computers. Unfortunately, I wasn't paying
- attention at the time. How do I do this?
-
- After a hiatus, I've decided I'm going to return to trying to program
- the ST again, so I want to make sure whatever I do will work on as
- many ST-type computers (i.e., STe, Mega STe, TT, Falcon, unusual
- configurations of those etc.) as possible (actually, working on all of
- them would be preferable).
-
- Thanks!
