About World Guard

From Modrinth

Mod that prevents your world from loading if its generator settings changed between now and the last time you loaded your world.

Chunk Wall

What is this?

  • World Guard is a mod that aims at preventing you from corrupting your world with awful chunk walls and missing biomes due to a changing seed or world generator or missing biomes.

How does it work?

  • Between world loads, World Guard locally saves basic information about your world's generator settings, dimensions, biomes installed mods, and installed datapacks. With this basic information stored, everytime the server starts, World Guard will run various checks including:
  • World Seed is the exact same. (config=crash_when_mismatched_seed=true)
  • Chunk generator settings and type are the exact same. (config=crash_when_mismatched_chunk_generator=true)
  • Ensuring no biomes have been removed from your server. (config=crash_when_removed_biome=true)
  • Ensuring no dimension were removed from your server. (config=crash_when_missing_dimension=true)
  • Ensuring the biome source used to sample biomes matches (config=crash_when_mismatched_biome_source=true)

What happens if it catches any of those errors?

  • World Guard will crash your game with the goal of preventing data corruption to your world's chunks by not letting the chunk's generate at all. The created crash report will give you very detailed information in regards to the before and after.

I am convinced my world will be fine!

  • Ensure you back up your world before deleting the <yourgameinstance>/config/worldguard/backup.dat file which will allow you to load into your world.

How do I configure this?

  • Config file for this mod can be found at <yourgameinstance>/config/worldguard/config.json
