問題是這樣子的 左右移動正常 只要一按下space就報錯 AttributeError: 'pygame.Surface' object has no attribute 'rect'
不太懂 請大神鑒別 以下是代碼

真的很急啊。。uj5u.com熱心網友回復：

"""在飛船所處的位置創建一個子彈物件"""super().__init__()
self.screen = screen
把你這句改成：
super(Bullet,self).__init__()
self.screen=screen
試試看如何？

今天看到了 不知道樓主還需不需要new_bullet = Bullet(ai_settings,ship,screen) 引數傳反了 改成new_bullet = Bullet(ai_settings,screen，ship)就行了
uj5u.com熱心網友回復：
抱歉現在才看到 確實解決了這個問題 謝謝你這么耐心看完了我這一長串代碼
uj5u.com熱心網友回復：
請問樓主，運行游戲主回圈的時候報錯，按空格鍵，出現說Bullet() takes 1positional argument but3 we're given 怎么回事，我看咱倆代碼一樣的啊uj5u.com熱心網友回復：
