Duplicationless Mod adds a background framework for other Minecraft projects to run properly. It handles common background tasks like reading settings files and saving block data. You only need to put this file in your mods folder if another mod asks for it.
Features:
- Works as a required background file for certain mods to load properly.
- Tracks mobs and items as they move between different chunks and dimensions.
- Manages block data storage to keep world files organized.
- Reads settings files so connected mods load their rules correctly.
- Puts common background code into one place to keep game files smaller.
