图搜索技术能够从图中寻找一条从起点到目标点的路径. 围绕游戏寻径问题,介绍了如何确定启发式函数进行启发式搜索,并把A*算法用程序加以实现,从而证明A*算法可以解决游戏中的寻径问题-Map search technology to search from a map to the target point from the starting point of the path. Around the game routing problem, describes how to determine the heuristic function, heuristic search, and the A* algorithm to achieve with the program, so that A* algorithm can solve the routing problem in the game
