snap to in 3D

[Raki]

-2 ways spring to mind.

1) Create a 2d grid then translate the world position of the model into 2d
sprite loc position. Then snap it to your grid.

2) or use a 3d grid (much the same as the other one) in that it's still 2d
only define to axis. Then again when in that grid snap the position to the
middle of that grid.

Probably require a list of the grid and continual checking of which grid
number you are in.
