Today, I finally realized the UI display, but it is still a preliminary, I have already displayed on the window, but I have not added an event response, but it will be realized. At this way, there is no big problem in basically UI, To resolve the input method, because in the game may enter Chinese, let all game players can chat with each other. Next, all write the UI part, then write window mode and full screen mode mutual conversion, but also check Whether the device is lost, etc. Write the code when writing a 3D device display mode is still very big. After a night, it is constantly working, it is finally achieved. So far, this 3D engine can show textured UI. There are a lot of things in the back, but also need to work hard.
