第一个windows作品

Your Ad Here 推箱子

//*******************************************************
//
// FileName  : Push The Box
// Author   : Star Fish
// Version   : 1.0
// Date   : 2005:04:04
// Coments   : 采用数组 10 * 10 来建立围墙、目标、箱子和人
//      其中 墙  1
//        目标 2
//        箱子 3
//        空余 4
//        人  5
//      坐标为 视窗原点左移一定位置为原点   
//      左边留出一部分输出 关数 和步数
//      本程序没有考虑 资源和速度
//    
//      其实该程序应该用，即一个大的数组来存储所有地图
//      用一个小的数组来表示正在用的一关地图
//      既节省空间，又提高速度
//      大地图的结构为 i，j，Sex，如果连着三个为6，6，6
//       则为一关， sex为 1，2，3，4，5
//      其它地方为 墙外
//      因为采用现在模式可以直接看到地图效果
//      
//      实际的时候应该将现在的数组转换为上面大的数组
//
//      问题有当搬动箱子的时候可以缩小刷新的区域
