我正在阅读这本关于 Python 的书,名为“为绝对初学者准备的更多 Python 编程”,在第 4 章中,您将创建这个炸弹捕捉游戏。我正在尝试修改它,以便您向炸弹或敌人射击。
我希望能够使用
pygame.draw.circle()
所以当你点击鼠标右键时它会射击,然后它会击中敌人并增加你的分数。顺便说一句 - 我已经知道如何在我只需要帮助拍摄形状时添加分数 :) 如果您想查看原始游戏源文件,请访问 - http://www.delmarlearning.com/ partners/content/1435459806/relatedfiles/index.asp?isbn=1435459806 它在第 4 章“BombCatcher”中
