Okay, I was finally successful at getting double-buffering to work
while remaining friendly with Intuition, but sheesh! it's slow!!!
I mean, using my '030 no sweat, but in 68000 mode it's really bad.
Here's my code:
(I have an array of 2 bitmaps)
void do_flip()
{
struct BitMap *BitMapt;
BitMapt=&bm_main[dbuff];
ms_p->BitMap=*BitMapt;
MakeScreen(ms_p);
RethinkDisplay90;
dbuff ^= 1;
}
(oops, the 90 is a ()).
anyway, there's gotta be a faster way, right?
MakeScreen and RethinkDisplay are just too slow.
Would some Amiga wizard please send me some Lattice code (e-mail)??
thanks in Advance!
