A datapack for Minecraft 1.19. This datapack is similar to X-Life, although there are a few changes.

Features of the datapack:
-You start with one heart.
-When you die, you gain a heart but loose a life.
-If you die with 10 hearts but 1 life, you get put into spectator.

Admins:
-Use '/function xlife:allreset' to reset the entire server's lives.
-Use '/function xlife:notifyload' to send everyone how many lives they have.
-Use '/execute as {PlayerName} run function xlife:selfreset' to reset only a specific players lives.
-Use '/scoreboard players set {PlayerName} lives {NumberOfLives}' to set a players lives.

If you have found any bugs or issues, please comment them.

I have not tested any other Minecraft versions and so they may or may not work with this datapack.

If people ask for it I may add a disable able way of getting lives back.
