Detailed Description

Defines a polyogn within a dtMeshTile object.

Member Data Documentation

areaAndtype

unsigned char AtomsUtils::dtPoly::areaAndtype

The bit packed area id and polygon type.

Note

Use the structure's set and get methods to acess this value.

neis

unsigned short dtPoly::neis[DT_VERTS_PER_POLYGON]

Packed data representing neighbor polygons references and flags for each edge.

Each entry represents data for the edge starting at the vertex of the same index. E.g. The entry at index n represents the edge data for vertex[n] to vertex[n+1].

A value of zero indicates the edge has no polygon connection. (It makes up the border of the navigation mesh.)

The information can be extracted as follows:

neighborRef = neis[n] & 0xff; // Get the neighbor polygon reference.
 
if (neis[n] & #DT_EX_LINK)
{
    // The edge is an external (portal) edge.
}

verts

unsigned short AtomsUtils::dtPoly::verts[DT_VERTS_PER_POLYGON]

The indices of the polygon's vertices. The actual vertices are located in dtMeshTile::verts.
