RecastBBTree Class Reference

Axis Aligned Bounding Box Tree. More...

Detailed Description

Axis Aligned Bounding Box Tree.

Holds a bounding box tree of RecastMeshObj components.
Note that it assumes that once an object has been added, it stays at the same world position. If it is moved, then it might not be able to be found.

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
