python - 为什么我的敌人子弹碰到我的玩家时没有删除
问题描述
所以我一直在努力让它当我的敌人子弹碰到我的玩家时，它会消失。我的问题是子弹会随机工作几次，然后在下一次击中玩家时出现此错误。
eguns.pop(eguns.index(egun))
ValueError: <__main__.main_loop.<locals>.enemybullets object at 0x06F69E50> is not in list
这里还有一个短片，显示正在发生的事情。 https://gyazo.com/f7718fd6b1200af3cf2f77d1a559fa46
当我被子弹击中时，我的游戏就冻结了。
这是不工作的部分
for egun in eguns:
for one in range(len(eguns)-1-1-1):
if egun.rect.colliderect(playerman.rect):
eguns.pop(eguns.index(egun)) # this is the code that was spouse to make the bullet dissaper
Lives -= 1
text2 = font.render("Lives = "+str(Lives),True,(0,0,0))
textRect2.center = ((600,65))

解决方案
嵌套循环没用。由于one从未使用过，因此您无论如何都不需要内部循环。
当您想从列表中删除一个元素时，在迭代它时，您必须获取列表的副本 ( eguns[:])。请参阅如何在迭代时从列表中删除项目？
. 遍历副本，但从原始列表中删除元素：
for egun in eguns[:]:
if egun.rect.colliderect(playerman.rect):
eguns.remove(egun)
# [...]
无论如何，这会容易得多，并且您不会像pygame中预期的那样分别使用pygame.sprite.Sprite,pygame.sprite.Group和。pygame.sprite.spritecollide()pygame.sprite.Sprite.kill()
