Pathfinding on a navigation mesh
Pathfinding on the navmesh requires the start and end locations as well as the navmesh that
needs to be queried. The position of the start point and end point isn't required to be direc-
tly on the navmesh, but can, instead, be up to 5 meters vertically or 2 meters horizontally
away from the mesh. The path returned will have the nearest start point and end point on
the navmesh if the original point resides outside the mesh. Snapping search points on the
navmesh allows agents to navigate back to the navmesh in case they navigate off the mesh
due to steering.
