Now we are facing a new problem with the buildings. The buildings are not well placed on the map. They overlap with each other in a very strange way. That is because we are now viewing the 3D isometric world in 2D screen with wrong ordering.
When we view the 3D perspective in the following way, the closer objects should block the view of the objects behind. The buildings in the preceding image do not obey this real-world rule and cause some strange overlapping. We are going to solve this problem in the next section.
