NavWorld.GetNodeType

Parameters

Returns

NavNodeType Polygon when the node is a polygon on a NavMesh surface.

Link when the node is a NavMesh Link or a generated link baked into a NavMeshData object.

Undefined when the node is empty and no query has produced it.

Description

Determines whether the NavMesh node is a polygon or a link.

Unity encodes the type in the NavNode identifier itself, so you can determine the type even after the specified node becomes invalid in the query's NavWorld. Use this method to decide whether to treat a node as a NavMesh surface polygon or as a link before you inspect its geometry.
