DynamicGridObstacle Class Reference

Attach this script to any obstacle with a collider to enable dynamic updates of the graphs around it. More...

Detailed Description

Attach this script to any obstacle with a collider to enable dynamic updates of the graphs around it.

When the object has moved a certain distance (or actually when it's bounding box has changed by a certain amount) defined by updateError it will call AstarPath.UpdateGraphs and update the graph around it.

Note
This script does only work with GridGraph, PointGraph and LayerGridGraph

When the DynamicObstacle is destroyed, a last graph update should be done to revert nodes to their original state

void Start ( )
