How do I make animations run that are looped and have a Humanoid in them?

I am a noob, and I'm following a video online. I made an animation of a bird with a Humanoid in it, and I don't know how to make it run. Its also set on loop. Here is a script I found:

local animation = Instance.new("Animation") animation.AnimationId = "http://www.roblox.com/Asset?ID=580342958" -- Local variables local animTrack = nil local canPlay = true

function playShockAnim(Source) if canPlay then local player = script.Parent.Parent canPlay = false animTrack = player.Humanoid:LoadAnimation(animation) -- Load animation into Humanoid canPlay = true animTrack:Play() -- Start the animation end end

playShockAnim(script.Parent.Parent)

Please help.
