Shared Inventory & Health is a multiplayer Minecraft datapack that links all players together by synchronizing their inventories and health.

Whatever happens to one player affects everyone.

Features

• Shared Inventory
  All players use the same inventory. Picking up, moving, dropping, or using an item is synchronized between players.

• Shared Health
  Damage and healing are shared between all players, so everyone effectively fights with the same health pool.

• Multiplayer Support
  Designed to work with 2 or more players, including larger groups.

• Death & Respawn Handling
  The datapack includes special handling for player deaths and respawning to avoid desynchronization and repeated death loops.

• Vanilla Friendly
  No mods are required. The datapack runs entirely on the world/server.

How It Works

Once the datapack is enabled, every player becomes part of the same shared system.

If one player:

• picks up an item, everyone receives the updated inventory;
• drops or moves an item, the shared inventory updates;
• takes damage, everyone’s health is synchronized;
• heals, everyone is updated accordingly.

This creates a completely different multiplayer survival experience where cooperation becomes extremely important.

One mistake can affect the entire team.

Important

Because all players are synchronized, unusual situations such as simultaneous item interactions, deaths, respawns, or multiple players taking damage at nearly the same time may behave differently from normal Minecraft.
