How to fix my Sword script so it doesn't attack when I'm not clicking?

Before the first click, when I touch the monster without clicking, the monster's hp doesn't go down. But, after the first click, whenever I touch the monster without clicking, the monster's hp will decrease. How to fix it?

PlayerName = script.Parent.Parent.Parent.Name
Tool = script.Parent
Damage = script.Parent.Settings.Damage
local ButtonPressed = false

Tool.Equipped:connect(function(Mouse)
	Mouse.Button1Down:connect(function()
----------------------------------------------------------------------	
		script.Parent.DamagePart.Touched:connect(function(hit)
			if not ButtonPressed then
				--is it not pressed?
				ButtonPressed = true
				-----------------------
				if hit.Parent then
				local human = hit.Parent
				hum = human:FindFirstChild("Settings")
				if hum then
					hum.HP.Value = hum.HP.Value - script.Parent.Settings.Damage.Value
					
					x = hit.Parent:FindFirstChild("Fighters")
					y = x:FindFirstChild(PlayerName)
					if not y then
						z = Instance.new("IntValue")
						z.Parent = x
						z.Name = PlayerName
					end
					
				end
				
				wait(1)
				end
				------------------------
				wait()
				ButtonPressed = false
			end
		end)
---------------------------------------------------------------------
	end)
end)
