WorldPack

by pippopippo233333

WorldPack lets a single instance hold several modpack setups, so a world can switch between them without reinstalling.

What it does

WorldPack is aimed at modpack creators who ship more than one pack. Instead of separate instances for a performance pack and a normal pack, each world can carry its own mod set and configuration files inside a single modpack, so the user only has to fetch one modpack.

Each packs world contains its own mods and configs, and one pack can overwrite the config files of another when the user chooses. The mod is client-side only, so it only needs to be installed on the player's client, and it runs on Forge and NeoForge for 1.20.1 and 1.21.1.

Imported .worldpack files come from other people, and the author warns that some may contain malware. Users should inspect such files with a file manager such as 7-Zip before opening them. WorldPack is published for 1.20.1 and 1.21.1 and is released under All rights reserved, so it is not open source.

Key features

  1. Per-world modpacks

    Each world can carry its own set of mods and configuration files, so one instance can hold several setups.

  2. Performance and normal packs

    A creator can ship a lighter performance pack and a full pack together and let the player pick between them.

  3. Config overwrite option

    A pack can replace the config files of another pack when the user wants that behavior.

  4. Worldpack export and import

    Setups can be exported as .worldpack files and imported again, including files shared by other people.

Use cases

Multi-pack distribution

A modpack author can distribute a performance version and a full version in one package, avoiding a separate instance for each.

Switching setups

A player can move between pack variants inside one instance without swapping modpacks.

Who it’s for: Modpack creators who ship more than one pack variant, and players who want those variants in a single instance. Only the client needs the mod, so server owners do not have to install it.

Questions

Which loaders does WorldPack support?

WorldPack is published for Forge and NeoForge, with files for 1.20.1 on Forge and 1.21.1 on NeoForge.

Does a server need WorldPack installed?

No. Only the player's game needs it, and servers run without it.

Is it safe to import worldpack files from other people?

The author warns that strangers' files may contain malware. Inspect them with a file manager such as 7-Zip before importing, and avoid files whose origin is unknown.
