This is a list of plugins and behaviors I've made:
Astar plugin, Pathfinder behavior (v1.0) [06/09/2012]
Auto tile behavior (v0.10)
Please note the Astar and Pathfinder are grid based.
Here is a tank RTS type example. It uses lines of sight to "smooth" paths and Lerp to make the movement more fluid.
P.S. This works really well with moveTo by @rexrainbow
