SeedMapper

This is a beta release because I have not confirmed the mod to be working on all operating systems. If you are on any of

• Linux
• MacOS arm64
• MacOS x86_64

please let me know whether the mod works!

Changelog

• Reduced the size of the JAR file by 0.79 MB (was 2.56 MB, now 1.77 MB).

Mod compatibility

Changelog

• Added advanced structure querying. This allows for locating structures with addition constraints on the structure. For example:

  • Search for the nearest village: /sm:locate feature structure village.
  • Search for the nearest end city with an end ship: /sm:locate feature structure end_city[end_ship].
  • Search for the nearest ruined portal that is both giant and underground: /sm:locate feature structure ruined_portal{giant=true, underground=true}.
  • Search for treasure bastions: /sm:locate feature structure bastion_remnant{start=treasure.big_air_full}.
  • Search for fortresses with blaze spawners and nether wart farms: /sm:locate feature structure fortress[bridge_spawner, corridor_nether_wart].

  The <structure>[...] syntax is for structure pieces, which is currently supported for end cities and fortresses. The <structure>{...} syntax is for structure variants, which is supported for many structures.

• Added a threading system. By doing the calculations in the background, this will make sure SeedMapper's search operations do not freeze the game.

Changelog

• Refined structure locating to prevent false positives. In particular, the accuracy of located end cities, desert pyramids, jungle temples and mansions will now be higher.
• Added the variantdata boolean parameter to the locate command: /sm:locate feature structure <structure> <variantdata>. If set to true, additional data about the structure variant will be printed. This includes data like the y-coordinate, the structure's starting piece, the structure's rotation, whether the structure is mirrored, and structure-specific data:
  • Whether a village is abandoned
  • Whether a ruined portal is giant
  • Whether a ruined portal is underground
  • Whether the ruined portal has an air pocket
  • The number of middle pieces of an igloo
  • Whether the igloo has a basement
  • The size of a geode
  • Whether a geode is cracked
• Added structure piece information for end cities and fortresses. If an end city has a ship, its location will be printed. Further, for all "monster thrones" (fortress pieces that have the blaze spawner) their locations will be printed.
