why won't this game start, it's looping [c

问题:

i have gone over every inch of this code i can not find out what is causing it to go into a loop. once i press key to start it plays the start noise and then it goes to the end screen and says press key to play again and i press it and it goes to start the game and plays the soung and one tick of the game and says game over.

回答1:

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

That break will be hit every frame, and immediately go to the 'Game Over' section at the end. I'm guessing you only intended this to happen if playerHasHitShoot returned true? If so:

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

It's less clear what the following bit (that's currently never running) is meant to do, but you should check and make sure all your conditional paths are correct:

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