Sorting
are sorters really so slow in games? :) I have made my unrolled version for my theoretical game (;), and it takes 132 rlines to sort 32 numbers o_O worst case is ~200 lines. tho when its the case of 4 numbers have to be swapped only it does the job in ~10 lines. wastes a lot of memory but I like it :) |

I mean to use that kind of indirection every time when you want to read Y coo.
so instead of
ldy sorted_virtual_sprite_pointers
lda ycoordinates,y
ldy sorted.....+1
cmp ycoordinsates,y
lda (sortedpointers),y
cmp (sortedpointers+2),y |

Yes that is what I did above. The load and cmp of y coordinates is faster, but the sorting of the indexes becomes slower. And with the double dey all in all the original implementation is faster (unless I missed something). |
