Simple A* path finding demo written in Python and working in Maya.
The Blue and Red nodes represent the current and required locations respectively and the black locators are nodes for a way-point graph. I didn't restrict this solution to a 2D grid of way-points as you would typically do in a conventional way-point based solution. I don't employ any path smoothing once the solver has generated a path so it looks a little "steppy" in its current form (the curve object in Maya is used purely for visualization purposes).
I wanted to see if I could quickly mock this up in Maya with the intention of re-writing it in Unity Script (C#) at a later date to be used in one of my concept projects.
for more information on the solver itself, review the following
