🫀 Single Heart – Minigame Datapack

Created by: MrLeon07

📜 Description

Each time you die, you permanently lose one heart.
Lost hearts can only be restored by eating Enchanted Golden Apples.
Each Enchanted Golden Apple restores exactly one heart.

If all hearts are lost, the player is forced into Spectator Mode permanently and cannot change their gamemode by any means.

The only way to return is by using a datapack-specific command
(Operator permission required).

/function singleheartpack:reviveplayer

Restores gameplay and gamemode
You can continue playing normally.

Revive another player

/execute as <player_name> run function singleheartpack:reviveplayer
