Class AIPathAlignedToSurface Extends AIPath

Public

Movement script for curved worlds.

This script inherits from AIPath, but adjusts its movement plane every frame using the ground normal.

A* Pro Feature:

This is an A* Pathfinding Project Pro feature only. This function/class/variable might not exist in the Free version of the A* Pathfinding Project or the functionality might be limited.
The Pro version can be bought here
