pygame 如何在同一屏幕上显示两个不同的动画

Question

我有一个问题，当我运行这个程序时，屏幕上显示的唯一动画是敌人而不是玩家，当我发射子弹（使用 for 循环）时，只有播放器和子弹显示。我无法将两者都放在屏幕上。我尝试将 player.draw() 和 enemy.ENEMY() 直接放在主 while 循环中，但结果是一样的。

    characters()

pygame.quit()

Answer 1

这是因为你在 enemy.ENEMY() 和 player.draw() 中都 blitting window 背景。这会清除 window，或覆盖其他图像。看来你应该删除那些，因为 characters() 也在 blitting 背景。
