So I did a thing....

[Methuselas]

With a lot of help from the guys on the UE forums, I have a working Grid Movement system. You can't see the grid, as it's hidden during game play, but you can set the X and Y to whatever you want. It works with the Z-axis, but the grid doesn't recognize it, as it's a 2D Grid. I have a working 3D one, using HISM that works with the Z-axis, but I haven't worked all the kinks out yet. There's a bool for development that allows you to switch between grid movement like Bard's Tale and free-form movement like Wizardry 8.
