In general, the shape of the universe is a sphere, centred on the Universe's position with diameter of the universe's size. The coordinates form a 3d rectalinear grid that the universe sphere marks the boundary of. In games that don't use the z coordinate (always 0), the universe is a circle, filled with square tiles (one for each coordinate). > Thanks! ;) Hope this helps Later Lee
