Navigation Mesh and Crowd Agents

With the new fun and simple Navigation Mesh system, leveraging the power of the excellent and open-source Recast navigation library, it's easier than ever to create convincing "AI" for your game or interactive experience. Simply provide a crowd agent with a navigation mesh, and the movement of that agent will be confined to the mesh. As seen with the fish in this Underwater Demo, you'll find it very useful for AI and path finding or to replace physics for collision detection (only allow player to go where it's possible instead of using collision detection).
