Question

我正在玩游戏，在这个游戏中我需要一个黄色的矩形显示在游戏窗口上，但是当我运行代码时，黄色矩形并没有显示出来。我正在Player()班级中绘制矩形。任何人都可以帮助我吗？

你根本不是在画画。唯一的绘图是在游戏的绘图方法中发生的，所以尝试添加：

def draw(self):
    self.screen.fill(WHITE)
    self.allSprites.draw(self.screen)
    pygame.display.update()

另外，顺便说一下，你的玩家的update（）方法不会运行，因为它是在 init 方法下缩进的。

无法弄清楚为什么精灵没有出现在我的屏幕上
