Question

我正在制作一个轮盘赌，它最终会被动画化。之前口袋里的数字是显示出来的，改了很多之后就没有了。我已经查看了一段时间的代码。

希望由于缺乏睡眠 + 初学者水平的专业知识，我错过了一些明显的东西。

      fclose( jpgImageFile );
      gdImageDestroy( Roulette );
    }

谢谢 :)（哦，还有欧洲轮盘）

Answer 1

真的很简单，我想我只是累了。

移除符号常量

#define WHEEL_DIAMETER IMAGE_WIDTH - 20

替换为整数

  int WHEEL_DIAMETER = IMAGE_WIDTH - 20;
