Train's Tweaks
by Partonetrain
Train's Tweaks lets modpack developers change hardcoded parts of Minecraft, such as experience, rarity and mob drops, through a config file.
What it does
The mod is a compilation port of several earlier tweak mods by Partonetrain, collected into one project across Fabric, NeoForge and Quilt. Its aim is to let users and modpack makers adjust behavior that Minecraft does not expose as options. Changes are made in the config menu, which the Configured mod provides, and the game should be restarted after a config option is changed.
Train's Tweaks depends on Fabric API and on Forge Config API Port, both required. Puzzles Lib is optional. The mod runs on the client and the server, so both sides need it. It is released under the MIT License and is open source, with public links for the source code and the issue tracker. Files target 1.21.1 only, with the latest Fabric file at 1.2.1 and the latest NeoForge file at 1.2.2.
Key features
Config-driven tweaks
Many hardcoded values can be changed in a config file, so modpack developers can tune the game without code.
SpawnsWith equipment tables
Mobs can roll equipment from generic or per-mob loot tables, with rolls scaled by local difficulty and spawn luck.
Equipment slot control
Separate tables cover main hand, off hand and armor, and drop chances are set in the table rather than the config file.
Carved pumpkin helmets
The Halloween pumpkin helmet is applied before equipment tables roll, so tables do not overwrite it.
