Well, your coding looks a bit funky.
Hmm, I take that back, alot funky.
You misstype code alot, hope it's only when you post.
But this is also a bad thing, becouse then we don't know the real problem and can't help you.
Look at code for minigun in objects.rfa.
Look at ad tracer part, it says 0.5/0/0.
This means that every time you shoot one bullit you don't, you shoot 2 tracers.
Change tracer to 0/0/0 and replace projectile.
Or replace tracer with a projectile.
At same time you can change firerate to 0.25.
All of this is in tutorial except tracer 0.5/0/0 and how to fix that.
Read it.
