How to Turn On Keep Inventory on Your Minecraft Server
Keep inventory is a gamerule. Once it is on, players keep their items and experience when they die.
From the console
Open Console while the world is online and type, without the slash:
gamerule keepInventory true- If the console says the gamerule is unknown, your version uses the newer snake_case name:
gamerule keep_inventory true.
In game
As an operator, type the same command with a slash. See How to OP players.
Good to know
Gamerules are saved with the world, so it stays on after restarts. Turn it off with false. On modded worlds, some mods add graves or their own death rules.
