hello,

im working on a space invaders game. i have it so your the ship. and you shoot the enemies and they blow up.
the enemies are images and when you hit them their picture changes to a blown up skull.
i need to know how to have the laser shoot past them once they've been hit. because the picture is black and the laser
just stops on the blackness. so i need to know how to get the laser to just go by. any ideas?
