SeedMapper

The seed map is out of beta! This stable release adds an explorable seed map to SeedMapper. The map can be opened in-game by pressing m (keybind is configurable) or by executing the /sm:seedmap command. The background texture is determined by the biomes (at sea level), where each biome has been given a colour. On top of the biomes, a few additional things are drawn: structures/features, ore veins, the world spawn point, waypoints, the player's position and more. What features will be displayed can be configured by clicking the toggles at the top of the screen. The map is infinitely explorable by dragging the mouse, and can be zoomed in/out by using the scrolling wheel. Moreover, you can copy the coordinates of the mouse's position by middle-clicking. By right-clicking you can place a (temporary) marker. The marker can be converted in to a permanent waypoint by entering a name in the bottom right text field and pressing Enter. For some structures, the contents of the chests can be inspected. These are:

• Buried Treasure
• Desert Pyramid
• End City
• Igloo
• Jungle Pyramid
• Ruined Portal (Overworld and Nether)
• Fortress (partial support)
• Bastion
• Pillager Outposts

The chests can be inspected by left clicking the structure. A chest-like GUI will pop up in which the different chests can be previewed using the < > buttons. By hovering over the title of the widget, additional technical information will be displayed.

Using the two text fields in the bottom middle of the screen, you can teleport around in the map. Like with real Minecraft worlds, the teleportation is limited to +/- 30000000 blocks.

By default, the map will use all available threads minus one to compute the seed map data. This can be configured using /sm:config SeedMapThreads.

As the map can be opened through a command, you can make use of the /sm:source command to completely change what parameters the map uses. For example, to view the biomes as they were in Minecraft 1.0, you can do /sm:source versioned 1.0 run sm:seedmap. You can similarly change the seed and dimension.

Note that by default, four pixels will be drawn per biome quart pos (a quarter chunk pos), which equates to one screen pixel per in-game block. This is because the precision of biomes is limited to biome scale (so up to quart pos) for efficiency.

Although the seed map is out of beta, I am still very open to feedback regarding it. So if you have any suggestions, or find a bug, please let me know!

Changelog

• Added an explorable seed map.
• Added loot support for Fortress, Pillager Outpost, Jungle Pyramid and Bastion loot. Of course, this applies not only to the seed map but also to the /sm:locate loot command.
• Added basic Shipwreck information when doing /sm:locate feature structure shipwreck{} true (loot support will probably follow soon).
• Added waypoints through SimpleWaypoints. They can be created from within the seed map, or by using the /sm:waypoint command.

If you find any bugs/have any suggestions, please let me know!

Changelog

• Added limited loot support for Bastions.
• Added technical chest information when hovering the title of the chest loot widget. Information includes the structure piece name, loot table name, loot table seed, and (sometimes approximate) chest position.
• Added waypoints through SimpleWaypoints. You can add a marker on the seed map by right-clicking the map. The marker will be saved as waypoint after you enter a waypoint name in the bottom right text field and press Enter. The waypoints in the seed map can be toggled on/off like any other structure. Copying hovered coordinates is now done by middle-clicking the map.

Mod compatibility

I have added support for the loot of two new structures! Both Fortresses and Pillager Outposts are now supported for both the /sm:locate and /sm:seedmap command.

If you find any bugs/have any suggestions, please let me know!

Changelog

• Added loot support for Fortresses and Pillager Outposts.

Changelog

• Added a chest loot preview widget. You can left-click a structure to open the preview. Note that, like for the /sm:locate loot command, only the following structures are supported: Buried Treasures, Desert Pyramids, End Cities, Igloos and Ruined Portals.

Mod compatibility

This release mostly adds "missing" functionality, I haven't gotten around to implementing most suggested features yet. Feedback is still very welcome!

Changelog

• Added the world spawn point as togglable feature to the seed map.
• Added teleport fields below the seed map.
• Made the number of threads used for the seed map configurable (/sm:config SeedMapThreads).
• Fixed a bug with calculating ore veins in the seed map.
• Added slime chunk highlighting to the seed map.

Mod compatibility

Changelog

• Added an explorable seed map. Description from the relevant PR:

  Relates to #51. This PR adds a seed explorer map (perhaps long overdue, for a mod called SeedMapper 😄). The map can be opened in-game by pressing m (keybind is configurable) or by executing the /sm:seedmap command. The background texture is determined by the biomes (at sea level), where each biome has been given a colour. The colours are from Cubiomes. On top of the biomes, a few additional things are drawn: structures/features, ore veins, and the player's position in the world. What features will be displayed can be configured by toggles at the top of the screen. The map is infinitely explorable by dragging the mouse, and can be zoomed in/out by using the scrolling wheel. Moreover, you can copy the coordinates of the mouse's position by right-clicking. By default, four pixels will be drawn per biome quart pos (a quarter chunk pos), which equates to one screen pixel per in-game block. Note that the precision of biomes is limited to biome scale (so up to quart pos) for efficiency.

  As the map can be opened through a command, you can make use of the /sm:source command to completely change what parameters the map uses. For example, to view the biomes as they were in Minecraft 1.0, you can do /sm:source versioned 1.0 run sm:seedmap. You can similarly change the seed and dimension.

  The map is intended as a quick way to explore a seed, similar to ChunkBase. As such, it is not my intention to make the map as feature complete as Cubiomes Viewer. This is also because the map runs alongside Minecraft, which makes rendering/UX much more complicated than with a standalone application, and means the map will not be as performant because the game runs in the background.

  I am planning to release this as a beta version of SeedMapper, because I would like to receive some feedback before I make a full release. So if you find bugs or have any suggestions, please let me know!

Changelog

• Re-added loot finding. The command for this is /sm:locate loot <amount> <item> [<enchantment conditions>]. Currently, the following structures are supported: Buried Treasures, Desert Pyramids, End Cities, Igloos and Ruined Portals. I hope to support Fortresses and Bastions too but those will have to wait. Also, the implementation of loot finding is much better than it used to be!
• Added the /sm:stoptask command. You can use this to cancel searches that are taking too long.

Mod compatibility

Changelog

• Added ore vein locating and highlighting. To locate an ore vein, you can do /sm:locate orevein. After this, you can highlight the entire ore vein using /sm:highlight orevein [chunks]. Raw ore blocks are highlighted distinctly. Filler blocks are ignored.

Mod compatibility

Changelog

• Added ore highlighting. The command for this is /sm:highlight block <block> [chunks]. The chunks parameter specifies the radius in chunks within which the ores will be highlighted. The highlights will disappear after five minutes, but they can also be manually cleared using the /sm:clear command. Additionally, the OreAirCheck config is added. When enabled, SeedMapper will use the in-game world to check whether there is air at the generated position. This can help in cases where the server does not obfuscate air around the player, but does obfuscate the other terrain.
• Added the /sm:buildinfo command. This command can be used to quickly check what version of SeedMapper you are using.

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 additional 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.

Mod compatibility

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.
