Protoncracker Engine
Protoncracker Engine is a Fabric configuration framework that lets players and server owners enable or disable other Protoncracker mods from one in-game screen.
What it does
Protoncracker Engine works as a core layer for the Protoncracker Framework and the mods built on it. A single configuration dashboard lists every recognized mod, grouped into server and client categories, with simple ON and OFF toggles for each option. The dashboard opens from a PCKR Engine button placed inside the standard Minecraft Options menu, so no separate program or file editing is needed for routine changes.
The engine also handles reloading. Editing configuration files and running the reload command re-reads them from disk and re-evaluates block replacement lists, recipe load conditions and worldgen or loot settings without restarting the game or the world. Server-side settings cover mob behavior and loot tables, while client-side settings cover rendering, scaling and tooltips. Mods that are loaded but not recognized by the engine appear in a read-only list, showing what the current environment runs. The mod is published for Fabric only, across 26.1 – 26.2, and it is licensed under the MIT License, not open source.
