Permanence Per Player Keep Inventory Add-on 1.21+

Every experienced crafter knows about the setting in Minecraft where a character's inventory is preserved without loss even after dying in lava. Unfortunately, not everyone is fond of this setting, and many want to make survival more challenging. Meanwhile, there are newcomers for whom inventory is extremely important. That's why the mod Permanence - Per Player Keep Inventory allows enabling and disabling inventory preservation for each player individually.

To activate it, you need to enter the command /scriptevent "permanence:toggle" [player's nickname]. If you don't specify a player's name, the command will apply to the person who wrote it. All other players will lose their inventory.
