I makemade a custom crafter in Minecraft 1.10.2. I want to obtain it by throwing a dropper and crafting table on the ground together. Everything is okOK, but if iI throw a dropper and a crafting table really far away from each other (crafting table far 50 blocks away from dropper), it still runruns. That's not ok. So, how to test thatif 2 item are nearby one to another in Minecraft?
