问题描述
我知道有几个关于这个的话题，但我仍然不知道如何让我的机器人发射多颗子弹......我想按下我的空格键并发射多颗子弹，但我仍然只能发射一颗子弹.我知道我的代码一团糟，所以我很抱歉.感谢帮助！
I know there have been several topics on this but I still can't figure out how to make my robot shot multiple bullets... I want press my Space Button and shoot multiple bullets but i still can shoot only one bullet. I know that my code is a mess so I'm sorry. Thanks for help!

推荐答案
好吧，在没有任何图像的情况下运行该代码会很困难，但从表面上看，您需要一种更好的方法来跟踪和更新子弹.例如，播放器类可以具有:
Well, it will be tough to run that code without any of the images, but from what it looks like is you need a better way of tracking and updating the bullets. For example, the player class could have:
self.bullets = []
然后任何时候你按下空格键，你都会添加一个新的项目符号:
Then anytime you press space bar, you would add a new bullet:
new_bullet = Bullet()
# Set up x and y of bullet and such (could add them to the constructor)
man.bullets.append(Bullet())
然后在您需要更新项目符号或绘制它们的任何时候:
Then anytime you need to update bullets, or draw them:
for each bullet in man.bullets:
bullet.x += .....
bulett.y += .....
# any additional updates and drawing and such
