There is no need to change the bodyguards to enemies m8.
Trust me on this.
I created a mod last year using lua that sets everyone fighting eachother...including the members of the same clique also fighting one another.
This is controlled with a few lua codes and you do not have to spawn any bodyguards to do this.
It is controlled via the PedSetPedToTypeAttitude(x, x, x) where the first x is the ped type (faction ...second number is the other faction or ped type you want their attitude to be changed towards and the third x is the attitude.
I will do a complete tutorial and writeup later tonight explaining how this works....this will allow you to edit the attitudes for everyone and not have to bother with changing a bodyguard to a enemy since this just kinda defeats the purpose of the mod in the first place.
This is kinda like selling your car for gas money......defeats the purpose and is a bit silly sounding when you think about it. Hopefully this makes some sense to you.
