Question

这是我的代码：

class MinerNotFullAction:
   def __init__(self, entity, image_store):
      self.entity = entity
      self.image_store = image_store

   def miner_to_ore(self, world, ore):
      entity_pt = MinerNotFull.get_position(self.entity)
      if not ore:
         return ([entity_pt], False)
      ore_pt = MinerNotFull.get_position(ore)
      if adjacent(entity_pt, ore_pt):
         MinerNotFull.set_resource_count(self.entity,
            1 + MinerNotFull.get_resource_count(self.entity))
         remove_entity(world, ore)
         return ([ore_pt], True)
      else:
         new_pt = next_position(world, entity_pt, ore_pt)
         return (worldmodel.move_entity(world, entity, new_pt), False)

   def miner_not_full_action(world, action, ticks):
      entity = action.entity
      entity_pt = MinerNotFull.get_position(entity)
      ore = find_nearest(world, entity_pt, entities.Ore)
      (tiles, found) = self.miner_to_ore(world, entity, ore)

      if found:
         entity = try_transform_miner(world, entity,
            try_transform_miner_not_full)

      schedule_action(world, entity,
         create_miner_action(entity, action.image_store),
         ticks + entities.get_rate(entity))
      return tiles

   def take_action(world, action, ticks):
      entities.remove_pending_action(action.entity, action)

      if isinstance(action, MinerNotFullAction):
         return self.miner_not_full_action(world, action, ticks)

      return []

当我不断收到此错误时：

Traceback (most recent call last):
  File "main.py", line 68, in <module>
    main(len(sys.argv) <= MIN_ARGS or sys.argv[INIT_ARG_IDX] != INIT_ARG_RANDOM)
  File "main.py", line 64, in main
    controller.activity_loop(view, world)
  File "/Users/KarenLee/CPE102/hw01/controller.py", line 50, in activity_loop
    handle_timer_event(world, view)
  File "/Users/KarenLee/CPE102/hw01/controller.py", line 27, in handle_timer_event
    rects = worldmodel.update_on_time(world, pygame.time.get_ticks())
  File "/Users/KarenLee/CPE102/hw01/worldmodel.py", line 78, in update_on_time
    tiles.extend(actions.take_action(world, next.item, ticks))
AttributeError: 'module' object has no attribute 'take_action'

感谢任何反馈！

您的包中有一个名为actions.py的文件。当你这样做

actions.take_action(world, next.item, ticks)

它在take_action()模块中查找actions.py并抛出错误。

从代码中可以清楚地看出take_action实际上是MinerNotFullAction的方法，因此行actions.take_action(world, next.item, ticks)应该为某个对象调用方法actions。这是一个命名冲突，因此错误

解决方案是将您的MinerNotFullAction对象（当前名为actions）重命名为其他内容

miner_action = MinerNotFullAction()

然后在代码中而不是actions.take_action执行miner_action.take_action。

即使你删除了这个命名冲突，也存在一些其他问题（正如人们在评论中已经说过的那样），特别是你的方法缺少self个参数。

为什么我在类中为方法获取此AttributeError？
