推箱子游戏

不知不觉工作有一段时间了，感觉总在忙碌，却不知道学到了多少东西，同样感觉到跟别人的差距越来越大。很多东西要学却又有些没有方向。工作也有些不稳定，心情挺郁闷的，动力都少了些。不吐槽了，言归正传。

界面用Qt实现的。

原理很简单，可以看到游戏里界面上有六种元素：

BoxAtDest = 0 ,
BoxOnRoad,
EmptyBlock,
TheBoy,
Wall,
Dest,
Error(暂时没有用到)

根据前面是什么元素来判断下一步数据如何更新，界面从数据取然后试图表现出来就可以了。

需要从txt文件里读取关卡内容。

想写一个自动推的路径算法，不过没想出来。

所有的源代码，程序里用到的图片就不贴了。。
