You know what, just fucking use tools already createdfor this purpose instead of asking AI for answers below:

MCA File Naming and Chunk Coverage (Corrected):

  • Region files (.mca files) represent a specific area in your Minecraft world.
  • The file name r.X.Z.mca denotes:
    • X - Region X coordinate.
    • Z - Region Z coordinate.

Crucial Error:

My previous explanation incorrectly stated that each region is 32x32 chunks. In reality, each region encompasses a 32x32 area of chunks, which translates to a total area of 512x512 blocks (as you pointed out).

Calculating Chunk Coordinates (Corrected):

  1. Region to Chunk Conversion: We directly multiply the region coordinate by the size of a chunk in blocks (512) to get the starting global chunk X/Z for that region.

Case of r.6.14.mca:

  • Global Chunk X: 6 (Region X) * 512 (Chunk Size in Blocks) = 3072
  • Global Chunk Z: 14 (Region Z) * 512 (Chunk Size in Blocks) = 7168

Point Range of r.6.14.mca (Corrected):

Therefore, the file r.6.14.mca covers the following chunk coordinates in your Minecraft world:

  • Starting Point (Top-Left Corner): (3072, 7168) chunk coordinates
  • Ending Point (Bottom-Right Corner): (3583, 7679) chunk coordinates

Explanation:

  • We obtain the ending point by adding the size of a region in chunks (32 chunks) minus 1 (to account for zero-based indexing) to the starting chunk coordinates in each direction (X and Z).
