[Archive]Prototype

Richard and Baotran made some models (about 20) first, and I selected some of them to add to the scene test. Specifically: all trees, flowers, candies and all buildings. But the textures of trees and flowers in this version have some problems and cannot be used.

At the same time, I also made a candy rain function, which can rain candies by pressing the L key. For this, I studied the manual of Spatial, clarified how to call some APIs, and also found that I seemed to be able to do more things in the future.
