This is probably a no-brainer, but I've had a bit of difficulty figuring it out. I am working on setting up some vanilla class systems for a PvP idea my friend and I thought up (not to be disclosed) and I need a way to make sure that players are keeping their items in their inventories. I know how to test for items in a player's inventory, and I know I could use a NOT gate after the testfor, but in a multiplayer environment that would ruin a bunch of stuff because whenever someone dropped something, everyone of the same class would get their stuff reset. So if there's a way to add like an ! in there or an alternative command, let me know, and I'm still open to suggestions if anyone has another idea. Also I am using the latest snapshots, if that helps (14w27b).
