absolute position of displayObjects/sprites/primitives


Recommended Posts


ive been struggling with the positions of sprites within displayobjectcontainers. Its hard to calculate the absolute position on the screen.

Ive been calculating it like this:

 var sx = attacker.sprite.position.x + attacker.sprite.parent.position.x; var sy = attacker.sprite.position.y + attacker.sprite.parent.position.y; var tx = target.sprite.position.x + target.sprite.parent.position.x; var ty = target.sprite.position.y + target.sprite.parent.position.y;

now im shooting lasers (another DOC) from sx|sy to tx|ty and im having a hard time to calculate whether the laser intersects with the target sprite since the positions 

of everything is pretty much fucked up. Is there a good way to get the "world"-position or "absolute"-position?
