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.
