Unity Pathfinding code - October 2012

Part of an assignment for Computer Game Programming (15-466) Fall 2012. Implements a standard A* search towards the moving player character. Each of the 10 characters calculates their path at random intervals to distribute processing time across multiple frames. Path calculation frequency increases as the characters move closer to the player. Project done in Unity3D 3.5.
Since this is a class project that is repeated annually, source code is only available by by request.
