vue實(shí)現(xiàn)五子棋游戲的詳細(xì)代碼

發(fā)布時(shí)間：2020-07-21 13:52:26 來(lái)源：億速云 閱讀：208 作者：小豬 欄目：web開(kāi)發(fā)

這篇文章主要講解了vue實(shí)現(xiàn)五子棋游戲的詳細(xì)代碼，內(nèi)容清晰明了，對(duì)此有興趣的小伙伴可以學(xué)習(xí)一下，相信大家閱讀完之后會(huì)有幫助。

思路

1.vue實(shí)現(xiàn)五子棋

空棋盤(pán)開(kāi)局。

畫(huà)網(wǎng)格：網(wǎng)格有 15 行 15 列，共有 225 個(gè)交叉點(diǎn)
黑先、白后，交替下子，每次只能下一子
勝負(fù)判定
按照簡(jiǎn)單的規(guī)則，從當(dāng)前下子點(diǎn)位的方向判斷()。如果有一個(gè)方向滿足連續(xù)5個(gè)黑子或白子，游戲結(jié)束。

2.支持dom和canvas切換

判斷瀏覽器是否支持canvas：

false: 不支持 切換dom方式
true:  支持 使用canvas

3.實(shí)現(xiàn)悔棋功能

4.實(shí)現(xiàn)撤銷(xiāo)悔棋

例子：

為了簡(jiǎn)便，我就把所有寫(xiě)在一起了，按理來(lái)說(shuō)是要分文件寫(xiě)的；
