Ok, am I being dumb here?
I have one variable, YPosFromBottom...this is how many
scanlines the top of the sprite is from the bottom...
if that number is less than 6, I assume it has hit the floor.
--snip--
;check if player hit floor
LDA #6
CLC
CMP YPosFromBot
BMI DoneCheckingHitFloor
;we need a better bounce routine, like reducing the speed?
LDA #-4;
STA PlayerVertSpeed
LDA YPosFromBot
STA COLUBK
LDA #10
STA YPosFromBot
DoneCheckingHitFloor
--snip--
The thing is, this seems to happen if YPosFromBot
is large, like maybe around 160, as well as small,
the under 6 I was hoping for. At least, that's
what I think I'm seeing, and I've been doing a lot
to isolate it (I had to...combined with my "have
I hit the ceiling routine, I was getting the sucker
freezing in place and acting otherwise confusingly...
other than this, I think my movement routine is
coming along very well...) Any suggestions what
I'm doing wrong here? Something with the carry bit?
Thanks for any help!

PS I actually have to 6502 books on order from the
library, but they're slow to get here over the
holidays...
