Subject: Aw: [stella] Question about HMOVE at cycle 71 From: cybergoth@xxxxxxxx Date: Thu, 14 Jul 2005 09:01:31 -0400 |
Hi there! > I looked at the trace log from Z26 to try to figure out what was going on. > When I position my sprites and hit HMOVE they're positioned at 69 and 82 > respectively. When I hit HMOVE again (no positioning this time) they shift > to 61 and 74. I do a HMCLR 2 scan lines after the HMOVE was done so why > are the sprites changing positions? Uhm... the second HMOVE was also on cycle 74? Please notice that all HMPX values are shifted 8 pixels when doing HMOVE @74, so when the HMCLR writes a zero "0" to the movement registers, it's actually saying "shift 8 pixels to the left". To effectively "clear" the motion registers for that trick, you'll have to individually load all affected HMXX with $80... (Either that, or *don't* HMOVE until it's really required again...)
