Create a punch tool?

So i already have a basic outline with two scripts, a local script for animation and a server script for damage. But its not working. Can anyone help?????

local tool = script.Parent
local player = game.Players.LocalPlayer
local character = player.Character
local humanoid = character:WaitForChild("Humanoid")
local isAttacking = false
local idleAnim = humanoid:LoadAnimation(tool:WaitForChild("Idle"))
local punchAnim = humanoid:LoadAnimation(tool:WaitForChild("Punch"))

tool.Equipped:Connect(function()
	idleAnim:Play()
end)

tool.Activated:Connect(function()
	print("Activated!")
	if isAttacking == false then
		isAttacking = true
		local rightArm = tool.Parent:WaitForChild("Right Arm")
		punchAnim:Play()
		rightArm.Touched:Connect(function(hit)
			print("Collided!")
			local humanoid = hit.Parent:WaitForChild("Humanoid")
			if humanoid then
				tool.TouchedEvent:FireServer(humanoid,hit)
			end
		end)
		wait(2)
		isAttacking = false
	end
end)

tool.Unequipped:Connect(function()
	idleAnim:Stop()
end)

There, that's the local script the root of my problem (probably).

• Nothing is avoiding the hand to touch on the lower arm and make the character do damage to itself.

• Sometimes touched event gives a list of parts that were touched almost together, so if the hand touches multiple body parts at once, it will give damage for every body part.

• You are not disconnecting your touched event after use, everytime you activate the tool it will create a new connection to the touch and multiple firings will start to happen the more you activate the tool till the game crashes.

• The Wait() function should be called inside a new thread or it can stop the rest of the script to run while it is waiting. Instead of using wait(), try delay() or put it inside a spawn(). And after you use this you will have to create a debounce sistem for the touch, like a cooldown.

• Looks like you did not played the punch animation
