Multiverse
by senseiwells
Multiverse lets server operators create extra dimensions at runtime with a small set of commands, each one a separate world with its own terrain.
What it does
Once installed, the multiverse command becomes available to operators. Creating a dimension uses the create subcommand, which has two branches. The first specifies a pre-defined dimension type and gives the new dimension a namespaced identifier, with an optional seed; without a seed one is chosen at random. The second gets the same identifier and seed choices and also lets the operator decide whether the dimension has its own gamerules or inherits them.
Dimension types control how terrain is generated and some behaviors. The vanilla types cannot be reused as identifiers because vanilla already uses them. Commands can be set to run only inside a specific dimension, and a dimension with its own tickrate is affected only by its own ticks.
Multiverse requires Fabric API and Fabric Language Kotlin, runs on the server alone, and is published for Fabric only across 9 release versions, 1.21.8 – 26.3, under the MIT License. Permissions for its commands can be changed with LuckPerms, which is optional.
Key features
Runtime dimension creation
Dimensions are created while the server runs, without editing world files or restarting into a new save.
Pre-defined dimension types
A new dimension can use a vanilla type or one of the three types the mod adds, such as a void or flat world.
Gamerule inheritance choice
The create subcommand decides whether a new dimension has its own gamerules or inherits the ones from the world.
Per-dimension tick control
Commands can run inside one dimension and affect only that dimension's ticks, or follow a custom tickrate.
