在PacMan游戏中创建自动运行PacMan的Java代码
我正试图从Mason 19网站修改pacman游戏。我要做的是让pacman自己运行,并尽可能快地遍历给定的任何棋盘。到目前为止,我已经实现了让pacman独立运行,但它在板的顶部陷入了一个循环。我想知道的是,什么才是使它工作而不陷入循环的最佳方式 我使用的程序代码来自Mason19 我修改的代码在Pac.java和doPolicyStep类中在PacMan游戏中创建自动运行PacMan的Java代码,java,auto,pacman,Java,Auto,Pacman,我正试图从Mason 19网站修改pacman游戏。我要做的是让pacman自己运行,并尽可能快地遍历给定的任何棋盘。到目前为止,我已经实现了让pacman独立运行,但它在板的顶部陷入了一个循环。我想知道的是,什么才是使它工作而不陷入循环的最佳方式 我使用的程序代码来自Mason19 我修改的代码在Pac.java和doPolicyStep类中 protected void doPolicyStep(SimState state) { if(lastAction

我相信我需要使用类似BFS搜索的方法来找到最短路径,我只是不知道如何做到这一点。“它陷入了一个循环中”,我在你的代码中没有看到任何循环,也没有看到
isPossibleToDoAction
做什么?代码中没有循环,但运行时在电路板的左上角有pacman循环。isPossibleToDoAction检查pacman运行时遇到墙时是否会在板上出现N、S、E或W。我的意思是你可以发布该方法的代码。@JoakimDanielson我编辑了原始帖子并包含了该方法。@JoakimDanielson我觉得我需要一个堆栈或类似的东西来跟踪每次移动。
