Lua Constant loop

[sestorme]

I want to create an addEvent which will constantly loop itself if a condition is met:

			function run(left)
				if (left > 0) then
				          doSendMagicEffect(getPlayerPosition(cid),5)
				          addEvent(run, 1000, left-1)
                                                    if (getCreatureMana(cid) >= 1) then
                                                    run(1)
                                                    end                              
				end
                                run(1)

And of course it don't loop.

Also tried like this:

			function run(left)
				if (left > 0) then
				doSendMagicEffect(getPlayerPosition(cid),5)
				addEvent(run, 1000, left-1)

				if (getCreatureMana(cid) >= 1) then
				
				function run(left)
					if (left > 0) then
					doSendMagicEffect(getPlayerPosition(cid),5)
					addEvent(run, 1000, left-1)
					end
				end

				run(1)

				end
				return true
				end
			end

			run(1)

I bet it's rather easy, it's just need to be implemented in the right way.
