SpriteMask
constSpriteMask:BuiltinComponentDef<SpriteMaskData>
Defined in: ecs/component.ts:962
Turns this entity’s Sprite into a stencil: the sprites drawn AFTER it that ask to be
masked (Sprite.maskInteraction) are cut by its shape. The mask’s own sprite is not
drawn while it is masking — it is the cut, not a picture.
