Need some help making this Animation Local and OnTouch, Please?

local char = script.Parent --the npc
local hum = char:WaitForChild("Humanoid") --the npc's humanoid
local animation = hum:LoadAnimation(script.Animation) 
if char ~= nil then
    animation:Play()
    animation:AdjustSpeed(0.5)
     --plays the animation
end

Hey, guys, do you think you can help me turn this into a Local Animation? So basically OnTouch it would trigger the animation for that one player and only that player and no one else can see that animation happen.
