Python實現五子棋人機對戰 和人人對戰

Posted on by

前言：

過完520，咱們來玩玩五子棋陶冶情操。快拿這個和你女朋友去對線。多的不說直接進入正題

人人對戰

遊戲規則：p1為黑子，p2為白子，黑子先手，一方達到五子相連即為獲勝。

定義黑白子，落子位置以及獲勝規則。

導入模塊

如出現模塊的錯誤，在pycharm終端輸入如下指令。

            pygame.gfxdraw.filled_circle(screen, Start_X + SIZE * i, Start_Y + SIZE * j, radius, BLACK_COLOR)

畫棋子

運行框返回落子坐標
