我知道有几个关于此的主题，但我仍然不知道如何让我的机器人发射多发子弹...我想按下我的空格按钮并发射多发子弹，但我仍然只能发射一颗子弹。我知道我的代码很困惑，所以我很抱歉。感谢您的帮助!

最佳答案
好吧，在没有任何图像的情况下运行该代码会很困难，但从看起来你需要一种更好的方法来跟踪和更新项目符号。例如，玩家类可以具有:
self.bullets = []
然后每当您按空格键时，您都会添加一个新项目符号:
new_bullet = Bullet()
# Set up x and y of bullet and such (could add them to the constructor)
man.bullets.append(Bullet())
然后，每当您需要更新项目符号或绘制它们时:
for each bullet in man.bullets:
bullet.x += .....
bulett.y += .....
# any additional updates and drawing and such
