Okay, so the game I'm working on has lots of items in it, and I don't want players dropping the items on their own, but after a certain point in the game, some of the items are useless, so I'd like to get rid of them. Is there anyway to make it so that the items do drop, but only at a certain point in the game? Like: The player has a key. There's a locked door. The player uses the key to open the door. As soon as the door is opened, the key is automatically dropped.
