Question

我已经超过了这段代码的每一寸，我无法找出导致它进入循环的原因。一旦我按下键开始它就会播放起始噪音，然后它会进入结束屏幕并按下按键再次播放然后我按下它然后开始游戏并播放游戏的一个标记并说游戏结束了。

if playerHasHitShoot(playerRect, baddieRect):
    score = 0 
break

每帧都会点击break，并立即转到“游戏结束”部分。我猜你只是在playerHasHitShoot返回true时才打算这样做？如果是这样的话：

if playerHasHitShoot(playerRect, baddieRect):
    score = 0 
    break

不太清楚下一位（当前从未运行过）是什么意思，但你应该检查并确保所有条件路径都是正确的：

if baddieHasHitShoot(baddieRect, shoot):
    if score > topScore:
        score = topscore
    break

为什么这个游戏不会开始，它会循环播放
