主要思路
1.画棋盘
小雨采用了最直接, 最暴力的方式, 就是把一堆小方块堆起来, 加上边框, 棋盘有了…什么? 你问我那五个点怎么画上去的? 页面上试出来的.
2.落子
落子是比较讲究的. 首先获取鼠标点击事件中的layerX, layerY, 这是鼠标点击的相对位置, 在本例中是比较好用的. 然后通过 getLayer() 函数获取点击点最近的网格点, 如下图, 鼠标点击在红框内则落子. 最后在相比网格点半个棋子位的地方落子就OK了.
3.判断获胜条件
isFive(list) { // 判断是否落成五子 this.isFiveInStraight(list, 0, 1); this.isFiveInStraight(list, 1, 0); this.isFiveInSlope(list, -1); this.isFiveInSlope(list, 1); }, isFiveInStraight(list, a, b) { // 判断五子是否在水平线或垂直线 let listSGT = {}; for (let i = 0; i < list.length; i++) { if (!listSGT[list[i][b]]) { listSGT[list[i][b]] = [list[i][a]]; } else { listSGT[list[i][b]].push(list[i][a]); this.isFiveNearby(listSGT[list[i][b]]); } } }, isFiveInSlope(list, slope) { // 判断五子是否在正斜线或反斜线 let listSLP = {}; for (let i = 0; i < list.length; i++) { let b = list[i][1] - slope * list[i][0]; if (!listSLP[b]) { listSLP[b] = [list[i][0]]; } else { listSLP[b].push(list[i][0]); this.isFiveNearby(listSLP[b]); } } }, isFiveNearby(arr) { // 判断五子是否相邻,连成一线 let idx = 0; let player = this.chessType === "black" ? "Black(黑)" : "White(白)"; if (arr.length >= 5) { arr.sort((a, b) => a - b) for (let i = 1; i < arr.length; i++) { idx = arr[i] - arr[i - 1] === 45 ? idx + 1 : 0; if (idx === 4) this.gameOver(player); } } },
这里主要有4个函数: isFive(), isFiveInStraight(), isFiveInSlope() 和 isFiveNearby().
isFive(): 这个只是调用后续函数的函数, 它将获胜条件分成了4类: 横线获胜, 竖线获胜, 斜率为1的斜线获胜 和 斜率为-1的斜线获胜.
isFiveInStraight(): 判断 横线获胜 和 竖线获胜 的功能函数. 这里的主要难点就是listSGT 对象的创建, 能否想到要用对象来实现落子的分类, 是这个函数的关键. 在 横线获胜 中, 将落子的layerY 坐标作为对象的属性, 将有相同layerY 坐标的棋子的layerX 组成一个数组作为属性的值. 竖线获胜 同理.
isFiveInSlope(): 判断 斜率为1的斜线获胜 和 斜率为-1的斜线获胜 的功能函数. 与 isFiveInStraight() 不同的是, 在创建listSLP 对象时, 以直线函数 y = k x + b y = kx+by=kx+b 中截距(b) 作为对象的属性, 以落子的layerX 坐标组成的数组作为属性的值, 其实用落子的layerY坐标也是一样的.
isFiveNearby(): 判断五子是否相邻的功能函数. 此函数直接获取上两个函数中所创建对象的值, 也就是落子坐标组成的数组. 首先判断数组长度是否大于5, 毕竟能少走一步是一步嘛. 之后将数组从小到大排序, 计算相邻两位的差, 并记录. 连续记录4次获胜.
