[Pharo-users] pathfinder object?

Hello, I am wondering if anyone has coded a pathfinding object in Smalltalk? I am working on one, but don't want to "reinvent the wheel". I am new to Pharo and Smalltalk, so this should be a good learning experience. I am using the A* algorithm for starters, but would like to have a variety of pathfinding options using different algorithms. Thanks, Jack
