我正在尝试将11张照片动画为带有pygame的动画。这段代码有效，但是当我运行它时，图片似乎几乎重叠。我为前几张图片做了window.blit并将它们放在else下？我觉得我错了。另外，我必须加上我非常擅长拿起人们想说的话，并从榜样中学到最好的东西。谢谢！

BTW：您的代码可能如下所示：

我在示例中使用了我的图像，但图像中仍然存在线条。

我使用计时器来改变图像 您可以按空格键暂停并退出以退出。

答案 1 :(得分：2)

通过一个接一个地放置所有window.blit(...)个调用， 将这三个帧相互叠加。即使您的计算机在每次通话之间滞后一秒钟，您仍然无法单独看到它们，因为在pygame.display.flip()被调用之前它们都无法显示。

您应该将图片存储在列表中，并保留一个从currentFrame到0（或number_of_frames-1）循环的len(frames)-1计数器。然后你在游戏的每一帧都做这样的事情：

class Player:
...
def draw(window):
    window.blit(self.frames[self.currentFrame])
