Constructors

this this(ubyte[] payload): Build packet with raw data

Members

Functions

bake void bake(bool removeBorders): Bake the existing walkmesh by re-creating tiles, islands, path tables, ...
buildEdges void buildEdges(): Rebuilds edge data by going through every triangle / vertices
dump string dump(): Dump trn data as text
findIslandsPath uint16_t[] findIslandsPath(uint16_t fromIslandIndex, uint16_t toIslandIndex): Calculate the fastest route between two islands. The area need to be baked, as it uses existing path tables.
removeTriangles void removeTriangles(bool delegate(in Triangle) removeFunc): Removes triangles from the mesh, and removes unused vertices and edges accordingly.
serialize ubyte[] serialize(): Serialize TRN packet data
serializeUncompressed ubyte[] serializeUncompressed(): Serialize the aswm data without compressing it. Useful for debugging raw data.
setFootstepSounds void setFootstepSounds(TrnPacket[] trrnPackets, Triangle.Flags[string] textureFlags): Set the footstep sound flags for each triangle of the walkmesh
setFootstepSounds void setFootstepSounds(TrnPacket[] trrnPackets, TwoDA terrainmaterials): ditto
setGenericMesh void setGenericMesh(GenericMesh mesh): Set 3d mesh geometry
toGenericMesh GenericMesh toGenericMesh(uint16_t triangleFlags): Converts terrain mesh data to a more generic format.
translateIndices void translateIndices(uint32_t[] triTransTable, uint32_t[] edgeTransTable, uint32_t[] vertTransTable): Translate triangle / edge / vertex indices stored in mesh data.
validate void validate(bool strict): Check if the ASWM contains legit data

Variables

edges Edge[] edges;: Undocumented in source.
header Header header;: ASWM packet header
islands Island[] islands;: Islands list. See Island
islands_path_nodes IslandPathNode[] islands_path_nodes;: Undocumented in source.
tiles Tile[] tiles;: Map tile list Non border tiles have header.vertices_count > 0 || header.edges_count > 0 || header.triangles_count > 0
tiles_border_size uint32_t tiles_border_size;: Width of the map borders in tiles (8 means that 8 tiles will be removed on each side)
tiles_flags uint32_t tiles_flags;: Always 31 in TRX files, 15 in TRN files
tiles_grid_height uint32_t tiles_grid_height;: Number of tiles along Y axis TODO: double check height = Y
tiles_grid_width uint32_t tiles_grid_width;: Number of tiles along X axis TODO: double check width = X
tiles_width float tiles_width;: Width in meters of a terrain tile (most likely to be 10.0)
