I change my spr render engine to a pixel one, i mean i apply what brad taylor says in his 2C02 reference, i think its the best way, cos its accurate as possible, but my unclear question is that he says that multiplexer do the following to choose if a spr pixel or bk pixel is drawn:
Code: Select all
if ((ObjPrioriy == FORGROUND) || (PFPixel == Transparent)) && (ObjPixel != Transparent)) PrintObjPixel() else PrintBKPixel
what about colour 0, when its drawn? some docs says that if bk pixel is xparent and sprite pixel is xparent it uses color 0. Am i wrong?
