Okay, I really need to know one thing. How do I make a weapon use lua? Like, is there a piece of code I need to insert somewhere for it to include the lua?

Check the coalition homing rocket launcher, it has the stuff you need. Just search for Lua in the file

thanks, ^.^

Thing to note: Weapons, when held, are considered Attachables, not separate MOs, and Attachables do not run any Lua. You have to work around this by making the round particles use Lua, or the Actor itself.

Or AEmitted particles.
