GraphModifier Class Reference

Detailed Description

GraphModifier is used for modifying graphs or processing graph data based on events.

This class is a simple container for a number of events.

Warning
Some events will be called both in play mode and in editor mode (at least the scan events). So make sure your code handles both cases well. You may choose to ignore editor events.

◆ AddToLinkedList()

void AddToLinkedList ( )

override void Awake ( )

Reimplemented from VersionedMonoBehaviour.

Reimplemented in DynamicGridObstacle.

◆ OnDestroy()

virtual void OnDestroy ( )
protectedvirtual

◆ OnDisable()

virtual void OnDisable ( )
protectedvirtual

Removes this modifier from list of active modifiers.

Reimplemented in NodeLink3, NodeLink2, DynamicGridObstacle, and RVONavmesh.

◆ OnEnable()

virtual void OnEnable ( )
protectedvirtual

Adds this modifier to list of active modifiers.

Reimplemented in NodeLink3, and NodeLink2.

◆ OnGraphsPostUpdate()

virtual void OnGraphsPostUpdate ( )
virtual

Called after graphs have been updated using GraphUpdateObjects.

Eventual flood filling has been done

Reimplemented in NodeLink3, NodeLink2, NodeLink, and RVONavmesh.

◆ OnGraphsPreUpdate()

virtual void OnGraphsPreUpdate ( )
virtual

Called before graphs are updated using GraphUpdateObjects.

◆ OnLatePostScan()

virtual void OnLatePostScan ( )
virtual

Called at the end of the scanning procedure.

This is the absolute last thing done by Scan.

Reimplemented in RVONavmesh.

◆ OnPostCacheLoad()

virtual void OnPostCacheLoad ( )
virtual

Called after cached graphs have been loaded.

When using cached startup, this event is analogous to OnLatePostScan and implementing scripts should do roughly the same thing for both events.

Reimplemented in RVONavmesh.

◆ OnPostScan()

virtual void OnPostScan ( )
virtual

Called right after all graphs have been scanned.

FloodFill and other post processing has not been done.

Warning
Since OnEnable and Awake are called roughly in the same time, the only way to ensure that these scripts get this call when scanning in Awake is to set the Script Execution Order for AstarPath to some time later than default time (see Edit -> Project Settings -> Script Execution Order).
Todo:
Is this still relevant? A call to FindAllModifiers should have before this method is called so the above warning is probably not relevant anymore.

Since OnEnable and Awake are called roughly in the same time, the only way to ensure that these scripts get this call when scanning in Awake is to set the Script Execution Order for AstarPath to some time later than default time (see Edit -> Project Settings -> Script Execution Order).
