Pett attack/follow macro

how to make a macro like vanilla?

/script if UnitExists("target") then if a==0 then PetAttack(target) CastPetAction(4) a=1 else if UnitExists("pettarget") and UnitIsUnit("target", "pettarget") then PetFollow() a=0 else PetAttack(target) CastPetAction(4) end;end; else PetFollow("") a=0 end;

ctrl 1 ctrl 2

Here's a way to make the toggle automatic -- if your pet is attacking, it'll call him back; otherwise he'll go to attack your target.

Code:

---

/petfollow [@pettarget,exists]
/petattack [@pettarget,noexists]
