hi, there I was wondering if anyone could help me with something I would like to know how to set up a command block where if a player was to chuck an item on the ground how would i get a command block to tp that item back to the player inventory???

You could have it be a hopper with a carpet on top, so when you throw the item the hopper will collect it and activate a command block giving you the same item back.

• Place a command block and set it to repeating and always active
• Put in: execute @e[type=item] ~ ~ ~ tp @p
