Python 简单的龟鱼游戏

游戏编程:按一下要求定义一个乌龟类和鱼类并尝试编程

  • 假设游戏场景为范围(x,y)为 0<=x<=10,0<=y<=10
  • 游戏生成1只乌龟和10条鱼
  • 他们的移动方向均随机
  • 乌龟的最大移动能力是2(乌龟可以随机选择移动是1还是2),鱼的最大移动能力是1
  • 当移动到场景边缘,自动向反方向移动
  • 乌龟初始化体力为100(上限)
  • 乌龟每移动一次,体力消耗1
  • 当乌龟和鱼重叠,乌龟吃掉鱼,乌龟体力增加20
  • 鱼不计算体力
  • 当乌龟体力值为0或者鱼的数量为0时,游戏结束

        # 判断 乌龟的移动是否超出了边界
        
        if new_x < 0:
            self.x = 0 - (new_x - 0)

    # 在迭代中做列表的删除元素是非常危险的,经常会出现一些意想不到的问题,因为迭代器是直接引用列表元素的数据做的操作
    # 所以 我们这里把列表拷贝一份传给迭代器,然后再对原列表做操作

            fish.remove(each_fish)
            print("有一条鱼被吃掉了")
