代码再检查一遍，确定没有问题

qiuyouzhi 发表于 2020-4-29 10:58:49

检查一下发生碰撞的代码，如果用到了函数，就检查那个函数。

wuqramy 发表于 2020-4-29 11:00:03

   #绘制我方飞机
   if me.active:
         if switch_image:
            screen.blit(me.image1,me.rect)
         else:
            screen.blit(me.image2,me.rect)
   else:
         #毁灭
         me_down_sound.play()
         if not(delay %3):
            screen.blit(each.destroy_images,each.rect)

            ifme_destroy_index == 0:
               each.reset()
可能是each没有赋值的原因
改成：
me.reset()
试试

谢谢~ 试了不行~

wuqramy 发表于 2020-4-29 11:07:30

那就把这一句enemies_down = pygame.sprite.spritecollide(me, enemies, False)换成enemies_down = pygame.sprite.spritecollide(me, enemies, False, pygame.sprite.collide_mask)再试试

主要问题是我方飞机，敌方飞机碰撞后都没发生爆炸

先把这一段的each都改成me
   else:
         #毁灭
         me_down_sound.play()
         if not(delay %3):
            screen.blit(each.destroy_images,each.rect)
            me_destroy_index = (me_destroy_index +1) % 4
            ifme_destroy_index == 0:
               each.reset()
然后把你的myplane.py和enemy.py发出来

另外上面说的我方飞机毁灭那里改成me.reset()也是必要的，因为我方飞机只有一架没有也不需要遍历。

他毁灭那一段有好多each

只是我方飞机毁灭不该用each.reset()，其他地方还是照样的，说实话，不报错我更加奇怪来着。。
