我有一個類似Pong的遊戲Pygame，現在看起來非常棒，但有幾件事我不明白。Pygame中的定位和速度問題
第一個問題是雙方的問題。我已經設置了蝙蝠使用左右箭頭鍵移動並在到達側面時停止（使用定位），但是如果按左側的左鍵或右側的右鍵，它會稍微離開比賽場地。
第二個問題，就像第一個問題一樣。我已經把球移動到了牆壁上（使用定位），但是如果球棒在左側或右側，並且我握住相應的鍵，球就會穿過牆壁/天花板！
最後一個問題是，我已經設置了球隨着時間的推移加速（使用速度）。如果你擅長比賽，那麼速度會加快，直到球速度如此之快，纔有能力擊穿蝙蝠。
這是我的代碼：

我真的需要這些東西幫助。提前致謝！
更新：我通過減少每次撞到後牆時增加的速度來解決最後一個問題，但我仍然需要前兩個幫助。我不明白速度x1與速度有關的事實1。它是與牆壁位置，還是它的碰撞？請幫忙！
海森堡有同樣的問題xD – eri
