Class Path Extends IPathInternals

Public Abstract

Base class for all path types.

Inner Types

Parameters to OpenCandidateConnectionBurst.

Public Methods

BlockUntilCalculated ()

Blocks until this path has been calculated and returned.

Public
CanTraverse (node)

Returns if the node can be traversed.

Public
CanTraverse (from, to)

Returns if the path can traverse a link between from and to and if to can be traversed itself.

Public
Claim (o)

Increase the reference count on this path by 1 (for pooling).

Public
Error ()

Aborts the path because of an error.

Public
FailWithError (msg)

Causes the path to fail and sets errorLog to msg.

Public
GetTagPenalty (tag)

Returns penalty for the given tag.

Public
GetTotalLength ()

Total Length of the path.

Public
GetTraversalCost (node)

Returns the cost of traversing the given node.

Public
IsDone ()

True if this path is done calculating.

Public
OnVisitNode (pathNode, hScore, gScore)
Public
OpenCandidateConnection (parentPathNode, targetPathNode, parentG, connectionCost, fractionAlongEdge, targetNodePosition)

Opens a connection between two nodes during the A* search.

Public
OpenCandidateConnectionsToEndNode (position, parentPathNode, parentNodeIndex, parentG)

Open a connection to the temporary end node if necessary.

Public
Release (o, silent=…)

Reduces the reference count on the path by 1 (pooling).

Public
ShouldConsiderPathNode (pathNodeIndex)
Public
UseSettings (settings)

Copies the given settings into this path object.

Public
WaitForPath ()

Waits until this path has been calculated and returned.

Public

Public Static Methods

OpenCandidateConnectionBurst (pars, heap, heuristicObjective)

Burst-compiled internal implementation of OpenCandidateConnection.

Public Static

Public Variables

CompleteState

Current state of the path.

Public
FloodingPath

True for paths that want to search all nodes and not jump over nodes as optimizations.

Public
PipelineState

Returns the state of the path in the pathfinding pipeline.

Public
callback

Callback to call when the path is complete.

Public
duration

How long it took to calculate this path in milliseconds.

Public
enabledTags

Which graph tags are traversable.

Public
error

If the path failed, this is true.

Public
errorLog

Additional info on why a path failed.

Public
heuristic

Determines which heuristic to use.

Public
heuristicScale

Scale of the heuristic values.

Public
immediateCallback

Immediate callback to call when the path is complete.

Public
nnConstraint

Constraint for how to search for nodes.

Public
path

Holds the path as a GraphNode list.

Public
pathID

ID of this path.

Public
searchedNodes

Number of nodes this path has searched.

Public
tagPenalties

Penalties for each tag.

Public
traversalProvider

Provides additional traversal information to a path request.

Public
vectorPath

Holds the (possibly post-processed) path as a Vector3 list.
