Just an update on this.
What I think I will do is make a basic capx that just sets up the isometric part, along with a detailed tutorial(perhaps a vid), on how to set things up.
From there you can set up what ever movements you like on a 2d layer.
If there is interest I will then make other capx's that do a specific movement type, for a separate charge. The reason for this that is there are basically two movement types, Pathfinder, and 8 Direction, but both of those deserve to have both mouse, and touch examples. Its about the same for paths, but a keyboard/ joystick input are much different.
