HTML5+JS 《五子飞》游戏实现（二）路线分析和资源准备

上一节 里沃特与我们分享了《五子飞》的下棋规则，可能有些伙伴看得不清楚，像我们码农还是看到代码比较靠谱。下面就把可以走棋的路线跟大家说一下。

 

假设从左上角开始，以0开始编号，往右数（没看第一节棋盘的先去看一下）（因为路线比较简单，就直接写固定的数据了）：

1.横着走有5条直线：

var lines_h = [        [ 0,  1,  2,  3,  4],        [ 5,  6,  7,  8,  9],        [10, 11, 12, 13, 14],        [15, 16, 17, 18, 19],        [20, 21, 22, 23, 24]];

2.竖着走也有5条直线：

var lines_v = [        [ 0,  5, 10, 15, 20],        [ 1,  6, 11, 16, 21],        [ 2,  7, 12, 17, 22],        [ 3,  8, 13, 18, 23],        [ 4,  9, 14, 19, 24]];

3.另外还有6条斜线可走：

var lines_o = [        [ 0,  6, 12, 18, 24],        [ 4,  8, 12, 16, 20],        [ 2,  6, 10],        [ 2,  8, 14],        [10, 16, 22],        [14, 18, 22]];

合起来即理论下可以走的路线如下：

// 可走的路线var lines = [        [ 0,  1,  2,  3,  4],        [ 5,  6,  7,  8,  9],        [10, 11, 12, 13, 14],        [15, 16, 17, 18, 19],        [20, 21, 22, 23, 24],        [ 0,  5, 10, 15, 20],        [ 1,  6, 11, 16, 21],        [ 2,  7, 12, 17, 22],        [ 3,  8, 13, 18, 23],        [ 4,  9, 14, 19, 24],        [ 0,  6, 12, 18, 24],        [ 4,  8, 12, 16, 20],        [ 2,  6, 10],        [ 2,  8, 14],        [10, 16, 22],        [14, 18, 22]    ];

分别用 A,B 表示对战双方：

var Player = { A: 0, B: 1, None: -1 };

棋盘我们直接在 canvas 上画，棋子准备两个小图片：

为棋子定义一个对象：

function Point(x, y, index) {    this.x = x;    this.y = y;    this.index = index;}function Bounds(x, y, w, h) {    this.x = x;    this.y = y;    this.w = w;    this.h = h;    this.toArray = function () {        return [this.x, this.y, this.w, this.h];    };    this.toArrayXY = function () {        return [this.x, this.y, this.x + this.w, this.y + this.h];    };}// 棋子function Chess(player) {    this.player = player;    this.point = new Point(-1, -1, -1);    this.bounds = new Bounds(-1, -1, -1, -1);    this.moveTo = function (chess) {        chess.player = this.player;        this.player = Player.None;    };}

棋盘上棋子定义（棋子初始化）：

var i;var cpc = 5;var ctc = Math.pow(cpc, 2);var chesses = [];// 分配棋子for (i = 0; i < cpc; i++) {    chesses[i].player = Player.A;}for (i = cpc; i < ctc - cpc; i++) {    chesses[i].player = Player.None;}for (i = ctc - cpc; i < ctc; i++) {    chesses[i].player = Player.B;}for (i = 0; i < ctc; i++) {    chesses[i].point = new Point(i % cpc, parseInt(i / cpc, 10), i);}

 

这样，路线和棋子初始化就已经比较清楚了，下一节我们开始在 canvas 上把棋子画好。
