This plugin basically replicates a cone of fire. It is distance based accuracy. Depending on how far away you are from your target, your bullet will be offset by a variable.
I created the plugin but never took it anywhere because I realised the DoD default cone of fire suffices for my purposes, but I figure someone will someday have a use for it, and by that time I might be long dead. So I figured I'd post it here in case anyone else wants to use it.
I have commented it all out so it should be relatively easy to follow.
