机器人推箱子代码

下面是一个简单的 Python 代码示例，使用广度优先搜索算法来实现机器人推箱子：

from collections import deque

# 地图中的符号定义
WALL = '#'
BOX = '$'
DESTINATION = '.'
ROBOT = '@'
EMPTY = ' '

# 定义机器人的四个方向
DIRECTIONS = [(0, 1), (0, -1), (1, 0), (-1, 0)]

# 使用广度优先搜索算法来寻找最优路径
def bfs(start, end, boxes, walls):
    visited = set()
    queue = deque([(start, boxes)])
    while queue:
        cur_pos, cur_boxes = queue.popleft()
        if (cur_pos, cur_boxes) == (end, tuple(sorted(boxes))):
            return True
        for dx, dy in DIRECTIONS:
            new_pos = (cur_pos[0] + dx, cur_pos[1] + dy)
            if new_pos in walls:
                continue
            if new_pos in cur_boxes:
                new_boxes = set(cur_boxes)
                new_boxes.remove(new_pos)
                new_box_pos = (new_pos[0] + dx, new_pos[1] + dy)
                if new_box_pos in walls or new_box_pos in cur_boxes:
                    continue
                new_boxes.add(new_box_pos)
            else:
                new_boxes = cur_boxes
            if (new_pos, tuple(sorted(new_boxes))) not in visited:
                visited.add((new_pos, tuple(sorted(new_boxes))))
                queue.append((new_pos, new_boxes))
    return False

# 加载地图
def load_map(filename):
    with open(filename, 'r') as f:
        lines = f.readlines()
    height = len(lines)
    width = max([len(line.strip()) for line in lines])
    walls = set()
    boxes = set()
    dests = set()
    for i in range(height):
        line = lines[i].rstrip().ljust(width, ' ')
        for j in range(width):
            if line[j] == WALL:
                walls.add((i, j))
            elif line[j] == BOX:
                boxes.add((i, j))
            elif line[j] == DESTINATION:
                dests.add((i, j))
            elif line[j] == ROBOT:
                robot = (i, j)
    return walls, boxes, dests, robot

# 主函数
def main():
    walls, boxes, dests, robot = load_map('map.txt')
    if bfs(robot, dests, boxes, walls):
        print('Success!')
    else:
        print('Failed!')

if __name__ == '__main__':
    main()

这是一个基础的推箱子游戏代码框架，你可以通过修改地图文件和算法实现自己的机器人推箱子游戏。
