Minecraft You can’t directly roll back the kill action of a player to get their items back, but you can roll back the items that they dropped in the area when they died. This would work regardless of what happened to the items after they died, whether they burned, fell into the void, were taken by another player, just despawned, or a mix of them all.
You need to know the location that the player died, and then you’ll need to perform a lookup to make sure that the item drops were logged. In the image to the right you can see that I died to fire and then dropped a number of items. You’ll need to run a lookup command to target just the item drops using the inventory action.
I used the following command to target all of the negative inventory transactions within 5 blocks of where I died. I ran the command while standing in the location, but there are other ways of defining the selection.
/co lookup user:mov51 action:-inventory radius:5 time:15m
To get the items back, all you have to do now is replace lookup with rollback and the items will be returned to the player’s inventory.
