Yea... an Isometric Movement Plugin would be REAL Nice! (One where you can adjust the angle of movement is what I really need...) I am in the planning stages for a Isometric (Hex based) tank game that I will have to write out a LARGE Event group for movement. If I have time today, maybe I will create a capx with what I come up with for the movement... We will see.
I was creating this little Tile Game that deals with Iso movement, but it is real glitchy. Maybe you can get ideas, though...
