-- a queue of items that i need to process in-game by using skills/spells 
while (queue is not empty) do

	getItemFromContainer() -- may fail
	processItem(head) -- this takes time, can fail, and uses mana. I also want to pause execution when I run out of mana to regenerate
	putItemInContainer() -- this step may fail as well
	removeCompletedItemFromQueue()
