Duality Switch
by JaaiDead
Duality Switch pairs two players into linked identities that take turns controlling one shared character, handing over at each phase change.
What it does
Players are automatically assigned paired roles, labeled D and N. At any moment, the game activates just one of these groups. When the phase timer runs out, the active players pass their complete state to their linked counterparts, and the inactive side stays cut off until the next swap. The result is a relay-style survival run in which two people continue the same journey in turn. The mod needs Fabric API, runs on client and server, and is published for Fabric only, for 1.21.1, under All rights reserved.
Key features
Paired identities
Each player gets a synchronized dual identity, and the two halves alternate control of the same character.
Automatic role assignment
Players are placed into D and N roles without manual setup, so each pair knows which side it starts on.
Phase-based handover
When the timer ends, active players pass their full state to the linked counterpart while the other side waits in isolation.
