| polygon | Identifier of a node from a NavMesh surface or link. |
NavMeshPolyTypes
Ground when the node is a polygon on a NavMesh surface.
OffMeshConnection when the node is a NavMeshLink or an Off-mesh Link.
Returns whether the NavMesh node is a polygon or a link.
The type can be determined even after the specified node has become invalid in the query's NavMeshWorld.
Known issue, to be fixed: If the query's NavMeshWorld is invalid for any reason, the method returns NavMeshPolyTypes.OffMeshConnection.
