What in god's name is wrong with my weapon?

[Treelor]

So I've taken it upon myself to create a gcombat weapon that behaves like a hybrid between the old Phaser Mk2 and the MW4 Energy Weapons I made for GCX long ago. The only problem is that this is now far more complex than the simple Flak 88 edits those energy weapons were.

Problems:
-does not seem to update self.TX/Y/Z variables, as self.Angle doesn't seem to compute anything except for a target vector to the map origin.
-does not fire. Ever. No errors.

Does anybody see what's wrong with this? I've got to be doing something wrong, this is my first foray into Lua since '07, so by all means tear this thing apart.
