通过自另一个类的功能在自主的功能

Question

我有两个班，第一个具有移动功能（生物，板）。然后在生物类中有一个调用移动的函数，那么在生物类中如何将当前生物传递给移动函数呢？如果它只是被移动（个体经营，self.board），因为当我尝试，我得到一个“来自导入未定义的变量： 移动”的错误？

下面是相关代码：

怪物：

class creature: 
    def __init__(self, social, intelligence, sensory, speed, bravery, strenght, size): 
     self.traits = [social, intelligence, sensory, speed, bravery, strenght] 
     self.x = 0 
     self.y = 0 
     self.hunger = 10 
     self.energy = 30 
     self.shelter = 0 
     self.dominance = 0 
     self.boardSize = size - 1 
     self.SOCIAL = 0 
     self.INTELLIGENCE = 1 
     self.SENSORY = 2 
     self.SPEED = 3 
     self.BRAVERY = 4 
     self.STRENGTH = 5 
... 
def performAction(self, action, location): 
     ...  
     if action == "storeFood": 
      food = location.vegetation 
      location.vegetation = -1 
      simulation.move(self, self.shelter) 
      self.shelter.foodStorage += food 
     ... 

模拟：

class simulation(): 
    def __init__(self, x): 
     self.creatures = {creature.creature():"", creature.creature():"", } 
     self.map = land.landMass 
     self.lifeCycles = x 
     self.runStay = ["rfl", "rbf", "rbl", "rbf", ] 
     self.befriend = ["bbl", "bbf"] 
     self.fight = ["fbl", "fbf", "bfl", "bff", "ffl", "fff"] 
...  
    def move(self, creature, target): 
      map[creature.x][creature.y].creatures.remove(creature) 
      creature.energy -= abs(map[creature.x][creature.y].elevation - target.elevation)/creature.getSpeed() 
      target.creatures.append(creature) 
      creature.x, creature.y = target.location 
      ... 

编辑： 行，所以我有所解决了这个问题。 Python的要求，我有simulation.simulation.map(self, self.shelter)我假设这意味着它不仅需要的类文件，而且这个类的一个实例。所以新的问题是我必须在其他地方将该实例传递给其他人吗？或者这可以在其他地方使用仿真实例吗？

继承了simulation类到creature类：

class Creature(Simulation): # I have inherited the functions from Simulation into Creature 
    ... 

现在不是simulation.move(self, self.shelter)，你想：

self.move(yourparameters) 

如果你注意到了，我大写的类名。 It's good to do so.
