What can i use to make a combo system?

this is not a request a wiki article or video would be nice

do people make combo systems using debounces, or a specific property, etc?

Yeah, so it'd be like

Local Combo = 0

MouseButton1Down:conncect(function()
	Combo = 1
		if Combo == 1 then
			--script
			Combo = 2
			MouseButton1Down:connect(function()
				if Combo == 2 then
					--script
				end
			end)
		end
		wait(timebeforecombowouldend)
		Combo = 0
end)

Or something along those lines
