keepInventoryWithoutXP

A datapack for a modified keepInventory gamerule that still clears your experience levels on death for those who don't want to lose their hard-earned equipment but still have some incentive not to die.
Note that this doesn't drop the XP but completely erases it!

To install put the zip file into your world's "datapacks" folder.
To uninstall run /function nj.keepinvnoxp:uninstall, which deletes the scoreboard that the pack needs to work and then disables the datapack. Afterwards you can remove the zip file from your world folder.
(uninstalling will set keepInventory back to false, regardless of what it was before)
