Magma Core
Magma Core is a NeoForge library that other mods build on, bundling shared code for updates, configuration and logging.
What it does
Magma Core holds basic code that other mods reuse. Its feature set includes an update checker, a version checker, a chat console logger, an in-game config screen and a debug mode. A stop-mod-reposts info message is also part of the core code. Helper methods for formatting, data generation and integration sit alongside these, so mod authors can call them instead of writing their own.
Seventeen catalog mods require Magma Core, among them Additional Structures, MineTraps, Lexicon, Customized Dungeon Loot and Tool Upgrades, so installing any of them means installing this library too. Servers that run it need every player to install it too. Builds cover 1.21.5 – 1.21.10, with files for 1.21.5, 1.21.9 and 1.21.10, and the latest file is v.2.1.1 for 1.21.10. The code is available as public source, but the mod is released under All rights reserved and is not open source.
