Jumploader

Jumploader is a mod that supports Fabric modpack exportation on Curseforge and Twitch (until November 30th 2020) and Fabric mods on the Curseforge launcher. It is applicable for Minecraft versions 1.14–1.16.4. It does not support Legacy Fabric. Before Jumploader, there only an unofficial method known as the "Vanilla to Twitch" method that specifically required files from the .fabric and .mixin.out folders from the Fabric regular launcher installation to be carried over to Twitch and Curseforge Launchers. It did not allow modpacks to be exported and was very limited in functionality and had poor usability with the launchers (such as the version profile requiring manual selection every time the user returned). Jumploader was a more simplified way to allow Fabric mods to work on the Twitch launcher more naturally and modpack exporting way for Fabric modpack creators to create and post modpacks to Curseforge.



Installation instructions

 * 1) Download Jumploader from Curseforge and place it in the mods folder of the modpack it will be applied to (or from a new/existing instance in the Twitch or Curseforge launcher).
 * 2) Launch the modpack from the launcher.
 * 3) A window with a green bar with "Jumploader" may appear the first time to inform the user it is setting up its requirements.

Before exporting a modpack to Curseforge (or setting up environments), Jumploader will


 * ignore Forge mods from the modpack
 * require a Forge modloader to be part of the modpack to apply the requirements for a Fabric modpack
 * require Asset Validator for 1.16 Snapshots and Pre-Releases. It it not required for exported 1.16.1+ Fabric modpacks as fixes have been made.
