Class NavGraph Extends IGraphInternals

Public Abstract

Base class for all graphs.

Public Methods

CountNodes ()

Number of nodes in the graph.

GetNearest (position, [...])

...

GetNodes (action)

Calls a delegate with all nodes in the graph...

IsInsideBounds (point)

True if the point is inside the bounding box of this graph.

IsPointOnNavmesh (position)

True if the point is on a walkable part of the navmesh, as seen from above.

NearestNodeDistanceSqrLowerBound (position, constraint=null)

Lower bound on the squared distance from the given point to the closest node in this graph.

OnDrawGizmos (gizmos, drawNodes, redrawScope)

Draw gizmos for the graph.

RandomPointOnSurface (nnConstraint, highQuality=true)

A random point on the graph.

RelocateNodes (deltaMatrix)

Moves the nodes in this graph.

Scan ()

Scan the graph.

Snapshot (bounds)

Captures a snapshot of a part of the graph, to allow restoring it later.

Public Variables

active

Reference to the AstarPath object in the scene.

Public
bounds
