You’d only change the middle value. When you move MAURICE offscreen it’ll tell you his coordinates and zone. You can place him in another zone when placing him offscreen as well. Whatever the middle number is, you’d use.
Here’s an awesome chart from the Episode guides that lays out the numbers:
Ex.
@MAURICE spot 1.412 420 0 in zone 1
@MAURICE walks to spot 1.412 270 0 in zone 1 AND MAURICE faces right
The spot direction IG post I linked has tons of detail regarding this.
