script.Parent.Touched:connect(function(Part)
	local Human = Part.Parent.Parent.Parent:FindFirstChild("Humanoid")
	if Human and Human.Parent.Name ~= Character.Name then
		Human:TakeDamage(20)
	end

Mouse.KeyDown:connect(onKeyDown)

I'm trying to make it where the player damages other players/npcs when you press the key.

game.Players.LocalPlayer.Character.LeftHand.Touched:connect(function(hit)
	local Humanoid = hit.Parent:FindFirstChild("Humanoid")
	if Humanoid and not leftready then
		Humanoid:TakeDamage(20)
	end
end)

game.Players.LocalPlayer.Character.RightHand.Touched:connect(function(hit)
	local Humanoid = hit.Parent:FindFirstChild("Humanoid")
	if Humanoid and not rightready then
		Humanoid:TakeDamage(20)
	end
end)

Add a debounce or else it will instakill your opponent, I'm too lazy right now lol.
