wtf is summertraining-homework?

This repository is a homework assignment for a summer training course, likely run by a student tech organization at Tsinghua University. It's designed to teach beginners how to set up a development environment on Linux and practice using two industry tools: Protocol Buffers (Protobuf) and CMake. The assignment walks students through defining a data structure for a video game character and then compiling that structure into a working program. At a high level, the homework asks students to define a "Player" with specific attributes like health points, a nickname, a job class, and held items. They do this by writing a special definition file (a .proto file) that describes this data. Then, they use a tool called protoc to automatically generate the actual C++ code from that definition. Finally, they write a small main program that creates a player named Alice, gives her 10,000 health and some weapons, and use CMake to turn all of this into a runnable application. The program also outputs a serialized binary file, which is a compact way of saving the player's data. The intended users are students learning C++ development in a Linux environment. The assignment gives them flexibility in how they access Linux: if they're on Windows, they can use WSL (a feature that runs Linux inside Windows) paired with Visual Studio Code, or they can run a full virtual machine. The concrete example here makes it easy to understand the goal, you're essentially building a tiny character sheet for a game and saving it to a file. The project is also notable because it connects to a larger, real-world project called THUAI5. The README links to actual Protobuf and CMake files from that project as optional further reading, so students can see how the tools they're learning are used in a bigger codebase. The assignment was due in July 2022, so it's a finished course exercise rather than an active project.
