Default World Type

Loading data...

A client-side mod that allows modpack creators to pre-define default world presets for streamlined world creation.


When you join a world, the mod will automatically generate a file at: <instance>/config/defaultworldtype/world-types.txt.

This file lists all possible values for the configuration. To set a default world preset, choose a value from the file and update the configuration. The selected preset will automatically be applied when players access the world creation screen.

In the config file, you can also choose to disable the preset selection button. This way, no other world type can be chosen.

If you also want to allow specific world types, you can use the allowed-world-types config by adding all world types to this list that should be selectable. However, all other presets will still be available when the user presses the Alt key, as in vanilla.

This mod is primarily intended for modpack creators. Regular players who only want to combine a few mods usually don't need it—unless they frequently create worlds with a specific world preset.
