FTBChecker

by SajmonOriginal

FTBChecker warns players at the title screen when essential FTB mods from a modpack are missing, and points them to where each one can be obtained.

What it does

Before the main menu opens, a screen lists any FTB mods that a modpack expects but the game does not have installed. The mod looks for the FTB projects modpacks most often rely on, each with a link to where the missing file can be fetched. Detection is automatic and runs each time the game starts.

The mod was first built for the CreateCore Reforged modpack, and its author later released it as a standalone mod so other modpack creators can include the same core FTB mods while keeping their projects compatible with licensing requirements. It is published for Fabric, Forge, NeoForge and Quilt on 1.18.2 – 1.21.1, with the latest Fabric and NeoForge builds for 1.21.1 and the latest Quilt build for 1.21. It is open source under the MIT License and runs on the client alone, so servers do not need it.

Key features

  1. Automatic FTB mod check

    On startup the mod scans the installed mods and detects the essential FTB mods that a pack depends on.

  2. Missing mods screen

    A warning screen appears before the main menu, listing each missing FTB mod by name.

  3. Links to missing mods

    Every entry in the warning screen links to the page where the absent mod can be fetched.

  4. Covered FTB projects

    The check covers the four core FTB libraries and quest and team systems that modpacks most often depend on.
