Struct TrnNWN2WalkmeshPayload

Compressed walkmesh (only contained inside TRX files) (ASWM)

Constructors

Name	Description
this (payload)	Build packet with raw data

Fields

Name	Type	Description
edges	TrnNWN2WalkmeshPayload.Edge[]
header	TrnNWN2WalkmeshPayload.Header	ASWM packet header
islands	TrnNWN2WalkmeshPayload.Island[]	Islands list. See Island
islands_path_nodes	TrnNWN2WalkmeshPayload.IslandPathNode[]
tiles	TrnNWN2WalkmeshPayload.Tile[]	Map tile list Non border tiles have header.vertices_count > 0 || header.edges_count > 0 || header.triangles_count > 0
tiles_border_size	uint	Width of the map borders in tiles (8 means that 8 tiles will be removed on each side)
tiles_flags	uint	Always 31 in TRX files, 15 in TRN files
tiles_grid_height	uint	Number of tiles along Y axis
tiles_grid_width	uint	Number of tiles along X axis
tiles_width	float	Width in meters of a terrain tile (most likely to be 10.0)
triangles	TrnNWN2WalkmeshPayload.Triangle[]
vertices	TrnNWN2WalkmeshPayload.Vertex[]

Methods

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

Inner structs

Name	Description
Edge	Edge between two triangles
Header	ASWM packet header
Island	Tile or fraction of a tile used for pathfinding through large distances.
IslandPathNode
Tile	Tile with its path table
Triangle	Mesh Triangle + pre-calculated data + metadata
