android中怎么實現(xiàn)一個五子棋

這篇文章將為大家詳細(xì)講解有關(guān)android中怎么實現(xiàn)一個五子棋，文章內(nèi)容質(zhì)量較高，因此小編分享給大家做個參考，希望大家閱讀完這篇文章后對相關(guān)知識有一定的了解。

需求分析

1 棋盤和棋子繪制2 按照五子棋的規(guī)則制定游戲勝負(fù)規(guī)則3 鼠標(biāo)響應(yīng) 在對戰(zhàn)中 需要通過鼠標(biāo)點擊下棋 進(jìn)行游戲的基本操作4 游戲模式 雙人對戰(zhàn) 兩人交替落子 雙方孰先孰后隨機決定5 棋子的形式和作用 棋子分為黑白兩種棋子 雙方各持一種棋子 通過黑先白后的方式來進(jìn)行對局6 通過棋子完成五連珠結(jié)束游戲
