;bit5=screen-bound? if set, this object must move in accordance with background layer 0
;bit6=object active? if set, this object is active and needs to be processed. if clear, this sprite doesnt need to be processed
;bit7=object present? if set, this slot has an object. if clear, its considered empty and can be overwritten

;bit5=bg-bound? if set, this object must move in accordance with background layer 0
;bit6=object active? if set, this object is active and needs to be drawn. if clear, this sprite doesnt need to be drawn, but must be processed, anyway

.db %00100000 ;object type designation 2
;bit7=pseudo 3d sprite that needs to be moved according to z-value when background moves
;bit6=don't upload tiles for this sprite. useful for stuff like particles and such where lots of sprites share the same tiles.
