- CPU-side
v_pos
variable tracking vertical screen position - We can retrieve that value in a render cog at the start of the
slgen
routine, and add it tocursl
while calculating the tile map line memory location, before loading it - To check wrapping, I think we just check if
v_pos + cursl >= MEM_TILE_MAP_HEIGHT * 8
after the the above step...
cursl: | 1 | |
---|---|---|
v_pos: | 15 | |
net: | 18 | |
max: | 16 | |
cmpsub net, max wc | ||
|___net= | 2 |
