How to detect a player's click without a tool? [SOLVED]

I'm trying to destroy a part when I click it. What I tried to do is below:

local mouse = game.Players.LocalPlayer:GetMouse()

mouse.Button1Down:Connect(function()
	mouse.Target:Destroy()
	warn("working")
end)

I'm using a local script but the warn doesn't work and neither does the destroying of the part. I also used a remote event to see if that would help, it accomplished nothing. I'd appreciate any help to this problem.

using clickdetector. it works so well that it will work with a part, or a model. basically you do this, put a script file right under the object you want to destroy,

local part = script.Parent
local cd = Instance.new("ClickDetector", cd)
cd.MouseClick:Connect(function(player)
	-- do whatever you want to destroy the part.
end)
