Game developers are partially transparent

If you have already completed the sorting function, expand your thinking and combine the two methods. If you provide two figures, one after the building, one is placed in front of the building (that is, two identical images place the building in the middle). If we set the Alpha value of the previous figure to 0.5, because of the overlay relationship, it is shown that the overlapping part of the building becomes translucent, while the rest is still opaque.

It only provides a way of thinking. The specific implementation details should be analyzed in detail.
