这是我遇到问题的部分：
if（player_health == 0）：
pygame.mixer.music.stop()
gameoverfont = pygame.font.SysFont("Power Green", 100)
gameovertext = gameoverfont.render("GAME OVER", True, white )
window.blit(gameovertext, (window_width / 2 - 160, window_height / 2 -75))
pygame.mixer.Sound.play(GAMEOVER)
pygame.display.update()
奇怪的是，文本在某些时候出现，并且它会在不同的时间内发生。我在录制此链接时出现了GAMEOVER文字的较长时间之一：https://www.youtube.com/watch?v=Xf8aKx4SOTc
如果有人能告诉我这里我做错了什么我会很感激，我对pygame本身很新。 编辑：好吧youtube似乎已关闭。基本上它是什么，是GAME OVER在消失之前显示大约1.5秒，然后游戏语音音频将播放两次。 （不知道为什么两次）
答案 0 :(得分：0)
首先你有两个if (player_health == 0):，试着加入所需的行只有一个，这应该解决声音播放两次的问题。
此外，您使用相同的名称hits来检测与子弹和怪物的碰撞，使用不同的名称会更容易阅读和更容易，这样做可以避免混淆得分。
当它的GAME OVER时，循环仍在运行，并且没有任何东西阻止分数增加或减少。
对于小怪的if hits:，您应该在测试中添加另一个条件，例如：
if hits and player_health > 0:
player_health = player_health - 1
否则您应该将运行状况测试更改为
if (player_health <= 0):
我希望这可以解决文本显示的问题。
