Spawn Dimension

How to relocate the world spawn location to another dimension.

Spawn Dimension Settings

When a different spawn dimension is set, the spawnpoint, starting structures, and spawn chunks move to that dimension.

Field	Type	Default	Description
dimension_id	string	"minecraft:overworld"	The dimension players spawn in, accepts any dimension ID.
respawn_mode	string	"last_dimension"	How the spawn dimension is determined on respawn, one of "last_dimension", "last_dimension_no_anchors", "always_spawn_dimension", or "vanilla" (see below for details).
keep_loaded	string	"spawn_dimension"	Which dimensions keep their spawn chunks loaded, one of "spawn_dimension" or "both" (see below for details).

Respawn Modes

Respawn modes determine the spawn dimension when a player dies without a spawnpoint set. Setting a new spawn with a bed or respawn anchor will work as normal.

Mode	Description
last_dimension (default*)	Spawns the player in whatever dimension their spawnpoint was last set.
last_dimension_no_anchors	Spawns the player in whatever dimension their spawnpoint was last set, excluding spawnpoints set with a respawn anchor (to prevent players getting stuck in the nether).
always_spawn_dimension	Always spawns the player in the spawn dimension.
vanilla	Always spawns the player in the overworld (vanilla default).

*If the spawn dimension is unset or set to the overworld, defaults to vanilla instead.

Chunk Loading Modes

When a spawn dimension is set, spawn chunks will be kept loaded in that dimension instead of the overworld. The keep_loaded setting can optionally allow the overworld spawn chunks to be loaded as well.

Mode	Description
spawn_dimension (default)	The spawn dimension is kept loaded, the overworld is not.
both	Both the spawn dimension and the overworld are kept loaded.

Example

{
    title: "Nether Start",
    description: "Spawn and respawn in the nether.",

    world: {
        name: "Nether Start",
        gamemode: "survival",
        difficulty: "hard"
    },

    dimension: {
        dimension_id: "minecraft:the_nether",
        respawn_mode: "always_spawn_dimension"
    }
}
