使用Imgui和SDL2做的一個彈球小游戲-Bounze

油管上面TheCherno博主分享的一個視頻FIRST GAME in C++! Did He Do a Good Job? // Code Review (C++/SDL2)里面分享了一個Github項目：

使用了Imgui和SDL2，并且可以設置音樂播放，修改音量等，玩家可以得分等，目前游戲支持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.

參考上述https://github.com/staticaron/Bounze的README.md文件，下載上述項目后，在Window11中使用VS2022打開下載的目錄，以CMake工程打開；
接著打開CMakeLists.txt，執行Ctrl+S編譯，生成Makefile等工程文件；最后將代碼根目錄下的resources資源文件夾拷貝到和bounze.exe同級目錄，運行bounze.exe可執行程序

然后鼠標雙擊bounze.exe可執行程序，

如果不拷貝resources資源文件夾，直接鼠標雙擊bounze.exe可執行程序，會報如下的錯誤：

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

加載資源文件報錯，因為找不到資源文件所在目錄。
