不采用pygame库，用python来实现推箱子小游戏

好的，以下是一个用Python实现推箱子小游戏的示例代码（仅供参考）：

# 导入必要的模块
import tkinter as tk

# 定义游戏界面的类
class Game(tk.Frame):
    # 初始化游戏界面
    def __init__(self, master):
        super().__init__(master)
        self.master = master
        self.pack()
        
        # 定义游戏地图和游戏元素
        self.map = [
            "####  ",
            "#@### ",
            "#  $  ",
            "#  $  ",
            "#   . ",
            "######"
        ]
        self.player_x, self.player_y = 1, 1
        self.box_x, self.box_y = 2, 2
        self.target_x, self.target_y = 4, 5
        
        # 创建游戏界面的组件
        self.create_widgets()
        
    # 创建游戏界面的组件
    def create_widgets(self):
        # 创建游戏地图的画布
        self.canvas = tk.Canvas(self, width=300, height=300)
        self.canvas.pack()
        
        # 加载游戏元素的图片
        self.wall_img = tk.PhotoImage(file="wall.gif")
        self.box_img = tk.PhotoImage(file="box.gif")
        self.target_img = tk.PhotoImage(file="target.gif")
        self.player_img = tk.PhotoImage(file="player.gif")
        
        # 在画布上绘制游戏地图和游戏元素
        for y in range(len(self.map)):
            for x in range(len(self.map[y])):
                if self.map[y][x] == "#":
                    self.canvas.create_image(x*50+25, y*50+25, image=self.wall_img)
                elif self.map[y][x] == "$":
                    self.canvas.create_image(x*50+25, y*50+25, image=self.box_img)
                elif self.map[y][x] == ".":
                    self.canvas.create_image(x*50+25, y*50+25, image=self.target_img)
                elif self.map[y][x] == "@":
                    self.canvas.create_image(x*50+25, y*50+25, image=self.player_img)
        
        # 绑定键盘事件
        self.master.bind("<Up>", self.move_up)
        self.master.bind("<Down>", self.move_down)
        self.master.bind("<Left>", self.move_left)
        self.master.bind("<Right>", self.move_right)
        
    # 判断游戏是否胜利
    def check_win(self):
        return self.box_x == self.target_x and self.box_y == self.target_y
    
    # 移动玩家和箱子
    def move(self, dx, dy):
        new_player_x, new_player_y = self.player_x + dx, self.player_y + dy
        new_box_x, new_box_y = self.box_x, self.box_y
        if new_player_x == self.box_x and new_player_y == self.box_y:
            new_box_x, new_box_y = self.box_x + dx, self.box_y + dy
        if self.map[new_player_y][new_player_x] != "#":
            self.player_x, self.player_y = new_player_x, new_player_y
            self.box_x, self.box_y = new_box_x, new_box_y
            self.update_game()
    
    # 上移
    def move_up(self, event):
        self.move(0, -1)
        
    # 下移
    def move_down(self, event):
        self.move(0, 1)
        
    # 左移
    def move_left(self, event):
        self.move(-1, 0)
        
    # 右移
    def move_right(self, event):
        self.move(1, 0)
        
    # 更新游戏界面
    def update_game(self):
        self.canvas.delete("all")
        for y in range(len(self.map)):
            for x in range(len(self.map[y])):
                if self.map[y][x] == "#":
                    self.canvas.create_image(x*50+25, y*50+25, image=self.wall_img)
                elif self.map[y][x] == "$":
                    self.canvas.create_image(x*50+25, y*50+25, image=self.box_img)
                elif self.map[y][x] == ".":
                    self.canvas.create_image(x*50+25, y*50+25, image=self.target_img)
                elif self.map[y][x] == "@":
                    self.canvas.create_image(x*50+25, y*50+25, image=self.player_img)
        if self.check_win():
            self.canvas.create_text(150, 150, text="You Win!", font=("Arial", 20))
        
# 创建主窗口并运行游戏
if __name__ == "__main__":
    root = tk.Tk()
    root.title("Push Box Game")
    game = Game(root)
    game.mainloop()

需要注意的是，由于没有使用pygame库，所以在实现游戏界面和游戏元素时，使用了Tkinter库的Canvas组件来绘制游戏界面。同时，由于没有使用外部资源加载函数，所以在代码中需要手动加载游戏元素的图片，并使用Canvas组件的create_image方法来绘制游戏元素。另外，由于没有使用pygame库的事件循环机制，所以在实现玩家移动和箱子移动时，使用了Tkinter库的键盘事件绑定功能。
