Public Methods

CountNodes ()

Public
GetNearest (position, constraint, maxDistanceSqr)

Nearest node to a position using the specified NNConstraint.

Public
GetNodes (action)

Calls a delegate with all nodes in the graph until the delegate returns false.

Public
GetNodes (action)

Calls a delegate with all nodes in the graph.

Public Abstract
IsInsideBounds (point)

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

Public
NearestNodeDistanceSqrLowerBound (position, constraint=null)

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

Public
OnDrawGizmos (gizmos, drawNodes, redrawScope)

Draw gizmos for the graph.

Public
RelocateNodes (deltaMatrix)

Moves the nodes in this graph.

Public
Scan ()

Scan the graph.

Public
Snapshot (bounds)

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

Public

Public Variables

active

Reference to the AstarPath object in the scene.

Public
bounds

World bounding box for the graph.

Public

Enable to draw gizmos in the Unity scene view.

Public
graphIndex

Index of the graph, used for identification purposes.

Public
guid

Used as an ID of the graph, considered to be unique.

Public
infoScreenOpen

Used in the editor to check if the info screen is open.

Public
initialPenalty

Default penalty to apply to all nodes.

Public
isScanned

True if the graph has been scanned and contains nodes.

Public Abstract
name

Name of the graph.

Public
open

Is the graph open in the editor.

Public
persistent

True if the graph will be included when serializing graph data.

Public
showInInspector

True if the graph should be visible in the editor.
