Hi Jack did you check PointerFinder? I can search for reasons why a certain object isn't garbage collected. I'm a quick port of a VisualWorks program written by Hans-Martin Mosner. Call me as shown below. I'll search for a path from a global variable to the given object, presenting it in a small morphic UI. Examples: PointerFinder on: self currentHand PointerFinder on: StandardSystemView someInstance Now, let's see why this image contains more HandMorphs as expected... HandMorph allInstancesDo: [:e | PointerFinder on: e] would be nice to get it a better interface..... Stef On Jan 25, 2010, at 1:46 PM, Jack Gibson wrote:
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 _______________________________________________ Pharo-users mailing list Pharo-users@lists.gforge.inria.fr http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users
