well it`s not a gun lol, it`s a spaceship. i`m not to sure what you mean though, i thought if i declared an entity like entity* enemy then i could use that as a pointer for the mesh to go to like my_scale.x = enemy.x; but that fails, eve nwhen it hits the enemy it passes through. and if the enemy is movewing as i will be then it wont be possible to use a block would it? i`d get the same problem of the beam passing through the enemy and seeing it passing out the other side.
