How to make it so a person doesn't spam the onTouched event ?(PLEASE LOOK)

How do I make this so a person can not spam the onTouched event?

`function onTouched() Instance.new("Hint", game.Workspace) wait() game.Workspace.Message.Text="Worked" wait(5) game.Workspace.Message:Remove()

end

script.Parent.Touched:connect(onTouched)`

Perhaps make sure that the object touching the part is an actual player, else any brick could touch it. ;)

function onTouched(Hit)
	local Player = Hit.Parent and Hit.Parent:FindFirstChild("Humanoid") and Hit.Parent.Humanoid.Health > 0 and game.Players:GetPlayerFromCharacter(Hit.Parent)
	if Player then
		local MSG = Instance.new("Hint", game.Workspace) -- Define this new instance with a variable. You'll have more control over the object you're making.
		wait()
		MSG.Text="Worked"
		wait(5)
		MSG:Destroy() -- This locks the message in "nil." ":Remove()" is deprecated.
	end
end

script.Parent.Touched:connect(onTouched)

Debounce is a very useful concept to learn. It means that you can only process one chunk of executions at a time. It's like regenerating a car (if you're an old ROBLOX player like me, you remember this ;)), the purple regenerating button turns black for a certain amount of time. Then becomes back to purple, allowing you to regenerate the car again.

The most common way of implementing this is to manipulate a static variable and wrap an "if" statement around your chunk of code.

Debounce = false

function onTouched(Hit)
	local Player = Hit.Parent and Hit.Parent:FindFirstChild("Humanoid") and Hit.Parent.Humanoid.Health > 0 and game.Players:GetPlayerFromCharacter(Hit.Parent)
	if Player then
		if not Debounce then
			Debounce = true
			local MSG = Instance.new("Hint", game.Workspace)
			wait()
			MSG.Text="Worked"
			wait(5)
			MSG:Destroy()
			Debounce = false
		end
	end
end

script.Parent.Touched:connect(onTouched)

Try adding and end) or end 2 times on the end

Debounce

debounce = false

function onTouched() Instance.new("Hint", game.Workspace) 
if not debounce then debounce = true
wait() 
game.Workspace.Message.Text="Worked" 
wait(5) 
game.Workspace.Message:Remove()
debounce = false
end

script.Parent.Touched:connect(onTouched)`
