We just released the game editor CopperCube in version 4.0.3, and besides other improvements, it also includes a much smarter Game AI now.

Yes, a screenshot won't show much here, but there is also a blog post which includes a WebGL demo showing the new features and explaining the details a bit: http://www.irrlicht3d.org/pivot/entry.php?id=1360
