How do I improve this punch script?

wait(2)

local player = game.Players.LocalPlayer
local Mouse = player:GetMouse()
Anim = script.Animation

Mouse.KeyDown:connect(function(key)
if key == "e" then
s = player.Character.Humanoid:LoadAnimation(Anim)
s:Play()
end
end)

I want to make it so that: -it does damage -there is sound -it doesn't inturrupt the walking animation.

You should use Cframing not an animation. Cframing also improves Damage so it doesn't hit the player 1000 times over.
