Shared Lives

Shared Lives is a Forge server-side mod for Minecraft 1.20.1 that links all players together through a shared health and hunger pool. Every hit, every meal, every death — felt by everyone.

Features

Health Synchronization

When a player takes damage, all online players receive the same amount of damage simultaneously — complete with the hurt animation and the hurt sound.
When a player heals (natural regeneration, golden apple, etc.), all players heal to the same health value.
When a player dies, every other player dies too — and all inventories are cleared.
A joining player's health is automatically synced to the group on login.

Hunger Synchronization

Food level changes are detected each server tick and propagated as a delta to all other players.
- Example: if a player eats and gains +4 food, everyone gains +4 food.
A joining player's hunger is synced to the group on login.

Action Bar Notifications

When a player takes damage, a configurable message is displayed on everyone's action bar, showing who took damage and how many hearts were lost.

Player Exclusions

Specific players can be excluded from all synchronization via the config file (by exact username, case-sensitive).

Configuration

The config file is generated at:

saves/<world>/serverconfig/playersync-server.toml

[general]
    # Enable health synchronization between players
    syncHealth = true

    # Enable hunger synchronization between players
    syncHunger = true

    # Players excluded from synchronization (exact username, case-sensitive)
    # Example: excludedPlayers = ["Steve", "Alex"]
    excludedPlayers = []

[messages]
    # Show an action bar message when a player loses health
    showActionBar = true

    # Message format. Placeholders: {player} = player name, {amount} = hearts lost
    # Supports color codes with &
    healthLostMessage = "&c{player} &flost &c{amount} heart(s)"

Use Cases

Hardcore co-op — if one person dies, the run ends for everyone.
Challenge runs — every mistake punishes the entire group.
Custom game modes — build your own shared-fate experience.
