[solved] Laser Beam

[IvanYiu247]

I recently made a Laser Beam Attack for Davis, but everytime it gets hit by Louis or Henry's Blastpushes, it'll be destroyed. How should I do to make it remain undestroyed when get hit by any attack? I even removed its body. Sorry, but I'm a little bit n00bish in DC.
