I'm really REALLY new to scripting, I honestly don't know much and I only know very very few things. I need help with this because I don't know how to do it myself. Thanks, hakerethan.
I think this should work
local Health = game.Players.LocalPlayer.Character.Humanoid.Health Health.Changed:Connect(function() if Health <= 20 then game.Players.LocalPlayer.Character.Humanoid.WalkSpeed = -- The walkspeed number
As for the animation I do not know, should be around the same gist of this though
