Read time 1 minuteLast updated 8 days ago

Definition

public virtual void OnGraphChanged(GraphLogger graphLogger)

Parameters

graphLogger

The GraphLogger that receives any errors or warnings related to the graph, and provides access to information about what changed (added/deleted/modified nodes).

Remarks

Unity calls this method after any change to the graph. Override it to validate the graph's integrity, log issues using the provided GraphLogger, or react to specific changes via GraphLogger.GraphChanges.
Use this method to detect invalid configurations, highlight issues in the editor, or provide user feedback. You can iterate the changed nodes efficiently without checking all nodes in the graph.
Do not modify the graph within this method, as it may cause instability or recursive updates.
