As the title of this topic says, i need to play an animation on a zombie.
i analyzed some treyarch scripts and they use this to play an animation by script

SetAnimStateFromASD

but i don't know how use it because doesn't exists in bo3 api reference.
I tried using Animscripted and obviously i setup the Animtree (UseAnimtree in script and .atr) but the zombie clears all animations for a moment and after that it continue to plays the previous animation it was playing but the animation that i want to play doesn't start 
I also tried using SetAnim but nothing...
Does anyone know the solution to this problem?
