Enumeration Type Documentation

enum CloseToDestinationMode

What to do when the character is close to the destination.

Enumerator:

Stop	The character will stop as quickly as possible when within endReachedDistance (field that exist on most movement scripts) units from the destination.
ContinueToExactDestination	The character will continue to the exact position of the destination.

enum ColliderType

Determines collision check shape.

Enumerator:

Sphere

Uses a Sphere, Physics.CheckSphere.

In 2D this is a circle instead.

Capsule

Uses a Capsule, Physics.CheckCapsule.

This mode is not supported in 2D.

Ray

Uses a Ray, Physics.Linecast.

In 2D this is a single point instead.

enum GraphDebugMode

What data to draw the graph debugging with.

Enumerator:

Areas
G
H
F
Penalty
Connections
Tags

enum GraphUpdateThreading

Enumerator:

UnityThread	Call UpdateArea in the unity thread. This is the default value. Not compatible with SeparateThread.
SeparateThread	Call UpdateArea in a separate thread. Not compatible with UnityThread.
UnityInit	Calls UpdateAreaInit in the Unity thread before everything else.
UnityPost	Calls UpdateAreaPost in the Unity thread after everything else. This is used together with SeparateThread to apply the result of the multithreaded calculations to the graph without modifying it at the same time as some other script might be using it (e.g calling GetNearest).
SeparateAndUnityInit	Combination of SeparateThread and UnityInit.

enum Heuristic

Heuristic to use.

The heuristic is the estimated cost from the current node to the target

Enumerator:

Manhattan	Manhattan distance. See Also https://en.wikipedia.org/wiki/Taxicab_geometry
DiagonalManhattan	Manhattan distance, but allowing diagonal movement as well.
Euclidean	Ordinary distance. See Also https://en.wikipedia.org/wiki/Euclidean_distance
None	Use no heuristic at all. This reduces the pathfinding algorithm to Dijkstra's algorithm. See Also https://en.wikipedia.org/wiki/Dijkstra%27s_algorithm

enum HeuristicOptimizationMode

Enumerator:

None
Random
RandomSpreadOut
Custom

enum NumNeighbours

Number of neighbours for a single grid node.

Since: The 'Six' item was added in 3.6.1

Enumerator:

Four
Eight
Six

enum PathCompleteState

State of a path request.

Enumerator:

NotCalculated	The path has not been calculated yet. See Also Pathfinding.Path.IsDone()
Error	The path calculation is done, but it failed. See Also Pathfinding.Path.error
Complete	The path has been successfully calculated.
Partial	The path has been calculated, but only a partial path could be found. See Also Pathfinding.ABPath.calculatePartial

enum PathLog

How path results are logged by the system.

Enumerator:

None	Does not log anything. This is recommended for release since logging path results has a performance overhead.
Normal	Logs basic info about the paths.
Heavy	Includes additional info.
InGame	Same as heavy, but displays the info in-game using GUI.
OnlyErrors	Same as normal, but logs only paths which returned an error.
