MoveMapGen.exe - cmangos/issues GitHub Wiki

With cmake Option "BUILD_EXTRACTORS" turned on, you will be able to build required data for your CMaNGOS Server to be fully functional.

Default mmap Extraction Values, which can be adjusted per map and tile in config.json

Generator command line args

--offMeshInput [file.*] Path to file containing off mesh connections data. Format must be: (see offmesh_example.txt) "map_id tile_x,tile_y (start_x start_y start_z) (end_x end_y end_z) size //optional comments" Single mesh connection per line.

--silent Make us script friendly. Do not wait for user input on error or completion.

--maxAngle [#] Max walkable inclination angle float between 45 and 90 degrees (default 60)

--skipLiquid liquid data for maps false: include liquid data (default)

--skipContinents [true|false] continents are maps 0 (Eastern Kingdoms), 1 (Kalimdor), 530 (Outlands), 571 (Northrend) false: build continents (default)

--skipJunkMaps [true|false] junk maps include some unused maps, transport maps, and some other true: skip junk maps (default)

--skipBattlegrounds [true|false] does not include PVP arenas false: skip battlegrounds (default)

--debugOutput [true|false] create debugging files for use with RecastDemo and Wavefront obj files of the navmesh if you are only creating mmaps for use with MaNGOS, you don't want debugging files false: don't create debugging files (default)

--tile [XX,YY] Build the specified tile seperate number with a comma ',' must specify a map number (see below) if this option is not used, all tiles are built

MAPID Build only the map specified by MAPID this command will build the map regardless of --skip* option settings If you do not specify a map number, builds all maps that pass the filters specified by --skip* options Maps that only consists of a wmo and no terrain will not be built unless specified with ID. Ex. Ragefire Chasm Examples:

movemapgen builds maps using the default settings (see above for defaults)

movemapgen --skipContinents true builds the default maps, except continents

movemapgen 0 builds all tiles of map 0

movemapgen 0 --tile 34,46 builds only tile 34,46 of map 0 (this is the southern face of blackrock mountain)

    {
        return {
            {"borderSize", 5}, -- Values: 1 - 5 (TC walkableRadius + 3) - dont use value below 5 as tiles dont connect then!
            {"detailSampleDist", 2.0f}, -- Values: 0.1 - 2 (TC 17) - For height detail only. Sets the sampling distance to use when generating the detail mesh.
            {"detailSampleMaxError", BASE_UNIT_DIM * 2}, -- Values: 0.1 - 2 (Default: ~= 0.5)(TC bigBaseUnit ? 0.5333333f : 0.2666666f) - For height detail only.
            {"maxEdgeLen", VERTEX_PER_TILE + 1}, -- Values: 81-85 (Default: 81) (TC bigBaseUnit ? 40 : 80 + 1) - The maximum allowed length for contour edges along the border of the mesh.
            {"maxSimplificationError", 1.8f}, -- Values: 1 - 2.5 (The effect of this parameter only applies to the xz-plane. eliminates most jagged edges (tiny polygons)
            {"mergeRegionArea", 10}, -- Values: 5 - 75 (TC 50) - Any regions with a span count smaller than this value will, if possible, be merged with larger regions.
            {"minRegionArea", 30}, -- Values: 15 - 90 (TC 60) - The minimum number of cells allowed to form isolated island areas.
            {"walkableClimb", 4}, -- Values: 3.5 - 10 (0.2666666f * walkableClimb) (TC m_bigBaseUnit ? 3 : 6) - "Old Info: keep less than walkableHeight - 0.5" - Maximum ledge height that is considered to still be traversable.
            {"walkableHeight", 3}, -- Values: 3.5 - 10 (0.2666666f * walkableHeight) (TC m_bigBaseUnit ? 3 : 6) - Minimum floor to 'ceiling' height that will still allow the floor area to be considered walkable.
            {"walkableRadius", 2}, -- Values: 1 - 5 (0.2666666f * walkableRadius) (TC m_bigBaseUnit ? 1 : 2) - The distance to erode/shrink the walkable area of the heightfield away from obstructions.
            {"walkableSlopeAngle", 60.0f}, -- Values: 50 - 90 - The maximum slope that is considered walkable. Dont Increase too much due to "Fear", though "Blink" also needs it to work, old Default was 70
        };
    }

Predefines:

BASE_UNIT_DIM:

// value have to divide GRID_SIZE(533.33333f) ( aka: 0.5333, 0.2666, 0.3333, 0.1333, etc )
// All are in UNIT metrics!
const static float BASE_UNIT_DIM = 0.2666666f; // 0.24242424f in Nostalrius Core -- WARNING: A bad 'BASE_UNIT_DIM' value will cause pathfinding issue between tiles.
