五子棋介绍 五子棋是起源于中国古代的传统黑白棋种之一。五子棋不仅能增强思维能力，提高智力，而且富含哲理，有助于修身养性。五子棋既有现代休闲的明显特征“短、平、快”，又有古典哲学的高深学问“阴阳易理”；它既有简单易学的特性，为人民群众所喜闻乐见，又有深奥的技巧和高水平的国际性比赛；它的棋文化源远流长，具有东方的神秘和西方的直观；既有“场”的概念，亦有“点”的连接。它是中西文化的交流点，是古今哲理的结晶。 游戏玩法 五子棋规则：棋盘采用15条横线×15条坚线组成交叉的每个点都可以放棋。 游戏分黑白两方，每局由规定黑方先行。黑方玩家移动鼠标在棋盘中点击行棋。当黑方行棋完毕，转由白方行棋。同色棋子在棋盘上形成横、竖、斜形成 “五子相连”则获胜。如果弃权，则判为输。 系统需求分析 五子棋游戏的基本功能如下： 下棋功能：此功能是五子棋的基本功能之一，主要是实现了鼠标点击的棋盘位置出现棋子 悔棋功能：下棋时下错棋子，则可以通过这个功能来取消下错棋子的步骤，从而达到悔棋的效果。 重新开局功能：当其中一个玩家无法继续完成一场游戏，或者当判断胜负之后棋盘扔保留的情况，可以通过这个功能来实现重新开新的一局游戏。 系统的设计与实现 项目工程结构
