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 will not work very good when using erosion on the grid since erosion is done in a post-processing step after scanning and is very difficult to update without rescanning the whole grid.

This script does only work with GridGraph and PointGraph

Revert graphs when destroyed.

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