ModpackLoaderFabric

Using this mod makes it very easy to download a ton of mods from a list of modpacks and keep them up to date.

Dependencies

None of these are required, they just add a user-interface for selecting mods. These will be automatically downloaded at first launch, restart the game to apply

• Fabric API
• Modmenu
• Cloth Config API

Usage

This mod uses the JSON format to store which mods to download and keep up to date. On startup, it searches Modrinth and CurseForge to see if a new version of the mods are available. If that is the case, ModpackLoderFabric will download the new version and delete the old version of the mod. If you had a mod installed before using ModpackLoderFabric, it will rename that mod to modname.jar.old. By default, the mod checks for updates only once a day to reduce startup time.

You can still add other mods manually, ModpackLoaderFabric will only automatically update your selected mods. All mods downloaded by ModpackLoaderFabric come with the suffix modname_MPLF.jar

⚠Unfortunately you have to manually restart the game to apply the newly downloaded mods, as reloading mods is impossible from within the game

Modpack from repository

The easiest method at the moment is to use my repository at modpack.wolfii.me. You can access all the modpacks from the config screen in modmenu under Hosted Modpacks.

Modpack from local file

If you want to create your own modpack, you can simply do so by creating a file in your /config/MPLF_Modpacks and selecting it from the config screen under Local Modpacks. This file format has to match the modpack format.

Modpack from external URL

Lastly, it is also possible to add a modpack by URL. This is done in the External Modpacks panel in the config screen. Modpacks added this way also have to match the modpack format.

Config

• Check for updates on game start - Disabling this option prevents the mod from making any further changes to your mods folder.
• Update interval - This option allows you to customize how often ModpackLoaderFabric will check for updates. Setting this to 0 (not recommended, launching takes a while) will check for mod updates on every game launch.
• Force update on next start - After selecting a new modpack it is recommended to also check this option as well, as the mod will probably skip update checking by default due to the update interval.
• Update on "Save & Quit" - This will immediately install or update your selected modpacks, this will take a while. Restart your game to apply the new mods.

Modpack format

The modpacks have to be stored in a JSON format

You can use a template over at modpack.wolfii.me to help making your own Modpack.
