這裏是我的代碼:(http://i.stack.imgur.com/SFyBJ.jpg)pygame的 - pygame中不能運行的乒乓遊戲碰撞
我每次運行它Pygame的窗口畫面,我沒有控制時間槳,然後它顯示遊戲結束。我一直在尋找很長時間,但找不到原因。看起來黑球運動速度如此之快,以至於比賽結束了大約一秒鐘。但我已經把速度設定在一個合理的範圍內,我很困惑。誰能幫忙?
第一次你失去了生命,你設置了'done'並且從不將它設置爲false。你必須稍微改進你的狀態機。同時在while循環中打印'myball.rect.top'和'screen.get_rect()。bottom'的值,您可能會感到驚訝。 –
在我的'if lives == 0'聲明中,我已將done設置爲True。在我的while循環中,我應該在哪裏添加用於打印'myball.rect.top'和'screen.get_rect()。bottom'的值的代碼? –
將它們打印到任何地方。只是在確定好之後 –
