to flexibly add three-person tables and five-person tables in the future. This is just a small attempt. In the future, the game will adopt this mechanism. Attackers can precisely control illegal exits. This project has great scalability. First, communication extensions can easily replace TCP connections, UDP connections, and HTTP connections. Second, it is easy to load new games, that is, plug-in technology, without modifying Hall programs. Do not bl

Apply a suffix to the Application name to distinguish the official version from the test version. During the development process, you usually encounter a device installed with an application that cannot determine whether the current version is debug or release. The previous practice was to enter the application and fi

parsing: Collections and arrays have many common places, both of which are used as data containers for holding data. The length of the array is fixed, but the length of the collection can be dynamically extended, and the array can be manipulated directly by its elements through the index, so the performance and efficiency are high. In practice, it is possible to use and co-operate to hold data for temporary variables, but to return the processing resu
