FTBLib Mod (1.19, 1.18.2) | Library for FTB Mods

FTBLib is a library mod for Minecraft 1.19 and 1.18.2. Download for Forge or Fabric. Edit configs in-game and use multiple game modes.

What is FTBLib?

FTBLib is a library mod that powers all the other FTB mods. If you’re running any FTB modpack, you need this installed first. It handles the backend stuff so the actual FTB mods can work properly. Once it’s in your mods folder, it mostly just sits there doing its job.

Key Features

  • Edit some config settings directly in-game instead of messing with files
  • Support for multiple game modes in the same modpack world
  • Works with both Forge and Fabric

How to Change Game Modes

FTBLib lets you switch between different game modes. Here’s how:

Minecraft 1.7.10

Type /ftb_mode set [mode] in chat, or go to saves/world/ and edit ftb_gamemode.txt

Minecraft 1.9.4 and Newer

Type /ftb packmode set [mode] in chat, or edit saves/world/world_data.json and change the "mode" value
