glad it works for you

If possible, do try to rotate your scene to the x and z coordinates. Lots of actions expect your scene to be that way. Also, I have not encountered any practical solution to work with a grid graph in any other dimensions, though I'm by no means an expert. I'll do some research tomorrow, though I expect that many astar settings, like height checks etc may also not work properly on any other plane.
Also, right now the movement actions either require a character controller or create a new one, so you would always be affected by gravity. I'll add a checkbox to make it possible to not use a controller at all, so you can hook up your own controller to the direction value.
The next update should aim for a better point graph integration, which should allow you to do such things by placing empties all over the scene and then automatically generating connections between them. I can send you the action once it's done if you like, since the actual next update may just take some time still.
