Map files and included tools

Steam build 25019767 contains 150 .sanmap files: 79 named maps and 71 generated ~FFA-* and ~TEAM-* maps. Those 71 prefixed maps are output from the shipped generator. The files begin with readable JSON metadata and the installation includes a separate map generator.

Start from a copied map. Change one field, use a distinct file name, and verify that the game lists it as a separate map. A complete .sanmap schema has not been documented.

The included README documents these command-line options:

--help: Shows command help.
--biomes: Lists or selects available biomes as described by the tool.
--styles: Lists or selects generation styles.
--seed: Sets the generation seed.
--map-size: Sets the generated map size.
--num-teams: Sets the number of teams.
--spawn-count: Sets the requested spawn count.
--folder-path: Sets the output directory.
--map-name: Sets the output map name.

The readable .sanmap JSON header is self-describing and includes fileVersion, mapVersion, width, heightmapResolution, and waterLevel before the remaining map data.

Compiled editor code

Trebuchet.dll contains an EM.MapEditor namespace for map selection, terrain, textures, props, decals, symmetry, lighting, water, undo history, and save or export UI. EM.Map.MapManager also contains a map-editor world and an IsMapEditor state.
