PointClickEngine::Navigation::PathfindingDebugRenderer

Inherits Reference < Object

Debug visualization for pathfinding and navigation

The PathfindingDebugRenderer provides visual debugging tools for pathfinding algorithms, navigation grids, and character movement. It should only be used during development and debugging.
