Detailed Description

Defines a navigation mesh tile.

Tiles generally only exist within the context of a dtNavMesh object.

Some tile content is optional. For example, a tile may not contain any off-mesh connections. In this case the associated pointer will be null.

If a detail mesh exists it will share vertices with the base polygon mesh. Only the vertices unique to the detail mesh will be stored in detailVerts.

Warning

Tiles returned by a dtNavMesh object are not guarenteed to be populated. For example: The tile at a location might not have been loaded yet, or may have been removed. In this case, pointers will be null. So if in doubt, check the polygon count in the tile's header to determine if a tile has polygons defined.
