Yup...but without the brackets since that could confuse someone.
It should be PedRecruitAlly(gPlayer, 2, true) which in this case 2 is Zoe since you can find the model numbers in default.ide located in your objects folder inside the main bully game folder.
if you remove true from this and just have PedRecruitAlly(gPlayer, 2) then you get a normal ally which is Zoe in this case.
You should never use 0 or 1 on the model ids since it will glitch very badly and you should also never use the id for the punching bag since even tho it is setup as a ped...it really can't do anything and just glitches the game up.
