General coding questions / Re: Twist Scroller - old Amiga effect
« on: September 14, 2011 »
@Hotshot:
Thanx!
I've used 6510 and 680x0 ASM many years ago. Then switched to C/C++, and lately doing some AS3 (flash), mainly for the purposes of recreating old C64 intros (like this one). But I guess language is not as important as is the logic behind it.
@jace_stknights:
Thank you for your answer. Yes, that was one of the ideas I had, but figured it would be a bit complicated and tiresome rendering precalc font 180x for each char and would end up eating too much space anyway, but that certainly is one of the ways of doing it. Some time ago I tried scanning through RAM while running Hardwired to see any gfx data resembling rotated chars (that would suggest precaclulating this), but found only 2d font and some parts of the twist effect without chars applied to them. This is how I figured it must be some other trick they must have used. But never tried looking for and disassembling the actual code as I suck at MC68k ML.
Anyways, thanx for your answer.
