Javafx实现国际象棋游戏

本文实例为大家分享了Javafx实现国际象棋游戏的具体代码，供大家参考，具体内容如下

目前创新互联建站已为成百上千家的企业提供了网站建设、域名、虚拟空间、网站托管、服务器租用、企业网站设计、庆云网站维护等服务，公司将坚持客户导向、应用为本的策略，正道将秉承"和谐、参与、激情"的文化，与客户和合作伙伴齐心协力一起成长，共同发展。

基本规则

  • 棋子马设计“日”的移动方式
  • 兵设计只能向前直走，每次只能走一格。但走第一步时，可以走一格或两格的移动方式
  • 请为后设计横、直、斜都可以走，步数不受限制，但不能越子的移动方式。
  • 车只能横向或者竖向行走
  • 国王是在以自己为中心的九宫格内行走
  • 骑士只能走对角线
