Updated.
Now fires in a strait line and not at the closest actor. When you miss it still shoots a (harmless) laser, and the fund dropping works for both teams. I've also added comments and slightly improved the function.

Want to add a secondary fire mode to this, but I need ideas. I was thinking of dropping the medkit and having the gun heal, you guys have any better ideas?

Enjoy!

Perhaps a weaker version of the beam that jumps to many more targets across a longer distance as the alt fire?

Maybe a Lua'ised version of the old one?
So it just damages actors in a straight line away from it in a longer range ignoring terrain.

A laser that arcs to more entities, but does less damage, and can jump before each actor dies.

...and we would have Red Alert 2's Prism Lasers! YAY!
somebody already did the tesla gun, now let's see the prism laser!
