I've got an arrow that drives the movement of a rectangle. I need the arrow to move freeform, but the rectangle to look like it is snapping to a grid made of 10x15 rectangles. Is there a way to make the movement of the rectangle follow the arrow but still constrain to the grid?

Thanks
Alex

Something like this maybe:

w = 10;
h = 15;

offset = [w,h]/2;

[Math.floor(value[0]/w)*w, Math.floor(value[1]/h)*h] + offset;


You'll probably want to fiddle with the offset til you get what you want.
