How would i get this animation to permanently loop?

i have a script that is supposed to make an animation permanently play on the zombie, but it doesnt work. In the animation editor i have set looped to true, and i have tried putting the animation:Play() in a while true do loop. Here is the script:~~~~~~~~~~~~~~~~~

local char = workspace.ZombieDoor.ZombieDecor

local AnimationTrack = char.Humanoid:LoadAnimation(ZombieAnimation)

AnimationTrack:Play()
