SeedMapper

Changelog

• Added a seed-based minimap. The seedmap can be opened by pressing , or by entering the /sm:minimap command. The minimap is very similar to the seed map in what it shows. The minimap can be tailored to the user's preferences by various configs:

  • RotateMinimap. Whether the minimap should rotate with the player. If true, the top of the minimap will show the biomes that are in front of the player. If false, north will always be up. Note that enabling the rotation incurs a minor performance hit, because more biomes need to be loaded at once to account for the rotation.
  • MinimapWidth. The width of the minimap in pixels.
  • MinimapHeight. The height of the minimap in pixels.
  • MinimapOffsetX. The amount of pixels that the minimap is offset from the left of the screen.
  • MinimapOffsetY. The amount of pixels that the minimap is offset from the top of the screen.

• Added terrain generation highlighting. This is a debug feature that must be enabled by doing sm:config DevMode set true. This command could for example be used to uncover what the terrain used to look like before player modification. The command is /sm:highlight terrain [<chunks>].

• Introduced support for large biomes, among other things. The user now has more control over the configured seed. Instead of a single world seed number, the seed config is instead a combination of values that identify a world seed. That is, now the seed config will consist of:

  1. the world seed;
  2. the Minecraft version;
  3. the generator flags.

  The second value allows the user to specify a Minecraft version that SeedMapper should use when using the seed. For example, if you play on a 1.19.4 server with the latest SeedMapper version, you can do /sm:config Seed <seed> --version 1.19.4. Now SeedMapper will always use this version for its calculations. Previously you had to prepend every command with /sm:source versioned 1.19.4 run. Of course, you can still use the /sm:source command to override the configured version.

  The third value allows the user to specify certain generator flags. Currently, these are large_biomes, no_beta_ocean and force_ocean_variants. For example, you can do /sm:config Seed set <seed> --generatorFlag large_biomes to enable the large_biomes generator flag. The generator flags stack, so you can repeat the --generatorFlag argument to add more flags. Also the generator flags can be overridden by the /sm:source command.
