用java实现推箱子(sokoban)游戏

1、推箱子游戏一、功能描述： 可以通过面板上的按钮或是键盘上的pageup,pagedown键选择上下关 可以通过面板上按钮或是键盘上的Backspace键后退，一直后退自己想要的位置，知道游戏开始时的位置。 可以通过面板上的按钮或是键盘上的字母r重新开始当前关卡游戏。 可以在复选框内选择想要玩的关卡。二、界面及运行截图 三、源代码(三部分)1、地图类package box;import java.io.BufferedReader;import java.io.File;import java.io.FileNotFoundException;import java.io.FileReader;
