Vertical callback or per pixel callback : I understand/How does Tilengine work?

[System64]

Hi!

From top priority to least priority, the draw stack is:

Top  ->      Priority sprites
                Priority tiles
                Regular sprites
                Regular tiles
Bottom ->  Background color or bitmap

• In layers of the same priority, lower indexes are drawn on top of higher indexes (so layer 0 always on top)
  
• In sprites of the same priority, there is a display list order that can be altered with TLN_SetFirstSprite() and TLN_SetNextSprite()
  

Hope this helps!

Hi!
So if I understand well, sprites layer is drawn 2 times and tiles layers are drawn 2 times too?
