Instant hit Laser?

I'm trying to make an instant hit, rotating laser. If it's not possible to make it instant hit, it should be very fast. Here is a picture oof what I mean... <img src="http://i280.photobucket.com/albums/kk182/codemonkeyaaaa/laser.jpg"> Anyone know how I can do this?

I would try using the bullet behavior. Shoot a bullet from the turret, use instant hit. Upon hitting a wall, set the x/y coordinates to private variables in the laser. Then then set the length of the laser by geting the distance from the laser's point of origin to the xy you set earlier.

Admittedly, I haven't tried this, but it should work in theory.

Yes but it works only in theory becouse i tried same ideology but it was failure becouse that instant-hit is a bit... inacurate , when using a detector with speed of 1000 it works pretty good yet its slow,

Here's a quick example.
