油管上面TheCherno博主分享的一个视频FIRST GAME in C++! Did He Do a Good Job? // Code Review (C++/SDL2)里面分享了一个Github项目：

使用了Imgui和SDL2，并且可以设置音乐播放，修改音量等，玩家可以得分等，目前游戏支持Windows和Linux。

Bounze

How to Play.

• The ball bounces off the bat randomly in normal mode.
• If boost is active, the ball bounces off according to where it collides with the bat.
• Balancing the ball on bat and destroying the diamonds using the boosted ball gives points.
• Get the highscore.

---

• I left the debug imgui in the game where you can modify the volumes etc. Press TAB to access.

How to build.

Windows + Visual Studio

1. Open the folder in visual studio as Cmake Project.
2. Ctrl + S on the CMakeLists.txt file to build the project.
3. Run bounze.exe.

NOTE : Copy the /resources folder in same directory as the .exe file.

LINUX

1. Create a folder /build
2. Enter the folder cd build
3. Run the cmake command cmake ..
4. Make the build file make

NOTE : Copy the /resources folder in same directory as the .exe file.

参考上述https://github.com/staticaron/Bounze的README.md文件，下载上述项目后，在Window11中使用VS2022打开下载的目录，以CMake工程打开；
接着打开CMakeLists.txt，执行Ctrl+S编译，生成Makefile等工程文件；最后将代码根目录下的resources资源文件夹拷贝到和bounze.exe同级目录，运行bounze.exe可执行程序

然后鼠标双击bounze.exe可执行程序，

如果不拷贝resources资源文件夹，直接鼠标双击bounze.exe可执行程序，会报如下的错误：

ERROR loading the font at : ./resources/fonts/mightysouly.ttf Couldn't open ./resources/fonts/mightysouly.ttf

加载资源文件报错，因为找不到资源文件所在目录。
