Nevermind this, everyone.
I have found a way to do it, using Saffith's autoghost script for a homing shooter. I modified it slightly, to make the safe distance a parameter in Misc. and I set the homing parameters high enough to render the homing nonexistent. The only thing I haven't figured out yet is how to make the enemies not knock link back (as real shooters do not have any effect when "touched").
Saffith, do you know how to do the above?
And thank you to Saffith and anyone else who looked at this thread.
EDIT: Nevermind the above request, I just discovered the SetOffsets function, and figured out how to tweak it such that the hitbox is 0, so there is no other issue.
