Handoff Relay

Handoff Relay

Handoff Relay is a Minecraft Fabric mod designed for timed, serialised gameplay handoff challenges.

The mod allows a Minecraft world to be passed between players while preserving player progression, timer state, inventory state, and world continuity between sessions.

Handoff Relay supports both:

• singleplayer/world-transfer workflows
• dedicated Fabric server hosted workflows

Core systems include:

• timed gameplay sessions
• reconnect timer continuation
• timer expiry enforcement
• expired player reconnect blocking
• player inventory persistence
• armour/offhand persistence
• ender chest persistence
• XP/health/hunger persistence
• potion/status effect persistence
• location and respawn persistence
• single active-player enforcement
• spectator account allowance
• configurable participant count tracking
• player order tracking (Player 1 of X, Player 2 of X, etc.)
• anti-creative / anti-flight enforcement
• dangerous command abuse blocking
• LAN cheat escalation mitigation
• persistent handoff save tracking
• backup save recovery
• integrity lock protection

The project is intended for:

• serialised gameplay recordings
• challenge runs
• collaborative survival handoff projects
• structured world-transfer events
• hosted sequential multiplayer experiences

Current project state:
Stable public release (v1.0.0).

Notes:
Handoff Relay is designed to preserve fair serialised gameplay progression between participants. Administrative filesystem tampering or deliberate world file modification is outside standard gameplay expectations and may affect continuity.
