This is actually a briliant way to solve this problem. I was thinking you'd have to use lua and complex trigonometry to get a gun to fire parralel bullets, but using AEMitters attached to a MOSRotating is a briliant way of letting cortex command do all the hard work for you.
Please excuse the terrible example sprite:
What you want is for the gun to fire a MOSRotating, the red bar, (that doesn't do anything) with 2 AEMitters attached, the blue bars, that emmit the actual particles that do damage (the green lines).
Code wise you need something like this:
(Note if copy/pasting from these forums into an ini file, you'll need to change the spaces in front of each line to tabs)
You'll need to put in all the names and probably also tweak various values, especially for the emitted particle. The parent offsets for the AEmitters might need to be tweaked as well. The AIFireVel and AILifeTime may not be needed at all, these are used purely by the ai for figuring out how to aim a weapon.
Edit: Fixed the code errors.
I thought i was just trying my luck when i requested an example. You will soon see this well used Thanks.
