[A86] Re: Some more questions...
Woa, yeah you're not going to want to use the disassembled source, cause all
of the labels will be hard to follow, the finished product of an assembly
program doesn't have any labels or comments assembled into the binary.... I
dont have the original source though, sorry. It wouldn't be hard to make
again though :)
And yes, that is correct, your description of masking and clipping. You use
masking so that you can have "clear" pixels in your sprite, it generally
consists of having a second bitmap that has all 1's on pixels that will be
changed by your real sprite (the other bitmap), so the routine will clear
any pixels that are set to 1 in the mask, and write their intended value
from the first bitmap, in this fashion, pixels that are 0 in the mask, wont
be chaged in the final.
I dont mind questions btw, i enjoy answering them :) it reminds me of back
in the day when i coded.
