i know this has been posted before but i can't find it.... how would i have 2 different ejections for bullets? like an overunder shotgun? or a gun with 2 barrels?

What do you mean?
Like a shotgun that ejects both shells when you reload, or something along those lines?
OR a gun that empties multiple casings at once?

You want to eject two casings?
Well, you can make a MOSRotating the casing that gibs into the two casing you want. To gib it you give it a lua script that gibs it on creation.

like you said miggles and you can do it with out lua it was quiet fun especially when you had 4 barrels
can fires one round then another

Like I said, how? I said two things.
Also besides the first 4 words of that sentence I could not comprehend what you were saying.

im sorry, the gun has 2 different muzzels that can fire bullets from 2 different locations

Hm. I'm fairly sure this can be done somehow, even if it surmounts to using a cheap emitter trick or two.

i do remember an emiter in there somewhere and was the message board cleaned a while ago? like 2 years?

Had to double post because i found it
