            this._timeLabel.setColor(cc.c3b(255,255,255));

            this.addChild(this._timeLabel,10);

        var imgLen =  LLK.CONTAINER.NORMALIMAGES.length;

        if(LLK.MODE){

            imgLen =  LLK.CONTAINER.NORMALIMAGES.length;

            for ( i = 0; i < LLK.LEVEL.x*LLK.LEVEL.y; i+=2) {

                this._blocks[i] = this._blocks[i + 1] = LLK.CONTAINER.NORMALIMAGES[Math.floor(Math.random() * imgLen)];

            }

        }

        else{

            imgLen =  LLK.CONTAINER.MENGIMAGES.length;

            for ( i = 0; i < LLK.LEVEL.x*LLK.LEVEL.y; i+=2) {

                this._blocks[i] = this._blocks[i + 1] = LLK.CONTAINER.MENGIMAGES[Math.floor(Math.random() * imgLen)];

            }

        }

        var imgName = "";

        for ( j=0; j < LLK.LEVEL.y; j++) {

            for ( i=0; i < LLK.LEVEL.x; i++) {

                imgName = this.randomArray(this._blocks);

                var temp = new Block(imgName);

                temp.pointX = i;

                temp.pointY = j;

                temp.name = imgName;

                temp.id = mapIndex;

                LLK.map[temp.id] = temp;

                temp.setAnchorPoint(cc.p(0, 0));

                temp.setPosition(i*60, j*60+30);

                this.addChild(temp);

                mapIndex ++;

            }

        }

        LLK.COUNT = mapIndex;

    },

    randomArray:function (arr){

        var index = Math.floor(Math.random()*arr.length);

        return arr.splice(index,1)[0];

    },

    scoreCounter:function () {

        if( this._state == STATE_PLAYING ) {

            this._time++;

            var minute = 0 | (this._time / 60);

            var second = this._time % 60;

            minute = minute > 9 ? minute : "0" + minute;

            second = second > 9 ? second : "0" + second;

            this._timeString = minute + ":" + second;

            this._timeLabel.setString(this._timeString);

//            this._levelManager.loadLevelResource(this._time);

        }

    },

    initBackground:function () {

        // bg

        var bgImage = s_b03;

        if(Math.random() > 0.5){

            bgImage = s_b04;

        }

        this._backSky = cc.Sprite.create(bgImage);

        this._backSky.setAnchorPoint(cc.p(0, 0));

        this._backSkyHeight = this._backSky.getContentSize().height;

        this.addChild(this._backSky, -10);

    },

    onGameOver:function () {

        this._state = STATE_GAMEOVER;

        var scene = cc.Scene.create();

        scene.addChild(GameOver.create());

        cc.Director.getInstance().replaceScene(cc.TransitionFade.create(1.2, scene));

    }

});

GameLayer.create = function () {

    var sg = new GameLayer();

    if (sg && sg.init()) {

        return sg;

    }

    return null;

};

GameLayer.scene = function () {

    var scene = cc.Scene.create();

    var layer = GameLayer.create();

    scene.addChild(layer, 1);

    return scene;

};

GameLayer.prototype.addExplosions = function (explosion) {

    this._explosions.addChild(explosion);

};

GameLayer.prototype.addSpark = function (spark) {

    this._texOpaqueBatch.addChild(spark);

};
　　首先，我们同样是把该界面所需的纹理集添加进来
cc.SpriteFrameCache.getInstance().addSpriteFrames(s_textureOpaquePack_plist);

this._heroFrameCache = cc.SpriteFrameCache.getInstance();

this._heroFrameCache.addSpriteFrames(s_textureNormalImage_plist);

cc.SpriteFrameCache.getInstance().addSpriteFrames(s_textureLoveImage_plist);

　　这里因为我们这个游戏存在这2个模式，所以有2个纹理集，之后的程序中会根据当前选择的模式对应使用纹理集。

　　之后添加爆炸效果的纹理集，创建cc.SpriteBatchNode然后把它加入Layer。
 　　　　　　// explosion batch node

            cc.SpriteFrameCache.getInstance().addSpriteFrames(s_explosion_plist);

            var explosionTexture = cc.TextureCache.getInstance().addImage(s_explosion);

            this._explosions = cc.SpriteBatchNode.createWithTexture(explosionTexture);

            this._explosions.setBlendFunc(gl.SRC_ALPHA, gl.ONE);

            this.addChild(this._explosions);

            Explosion.sharedExplosion();
　　接下来便是初始化背景和Block，背景的我们在教程1有介绍这里就不再多说，说说initBlock方法吧
　　initBlock:function(){

        var mapIndex = 0,i = 0,j = 0;

        var imgLen =  LLK.CONTAINER.NORMALIMAGES.length;

        if(LLK.MODE){

            imgLen =  LLK.CONTAINER.NORMALIMAGES.length;

            for ( i = 0; i < LLK.LEVEL.x*LLK.LEVEL.y; i+=2) {

                this._blocks[i] = this._blocks[i + 1] = LLK.CONTAINER.NORMALIMAGES[Math.floor(Math.random() * imgLen)];

            }

        }

        else{

            imgLen =  LLK.CONTAINER.MENGIMAGES.length;

            for ( i = 0; i < LLK.LEVEL.x*LLK.LEVEL.y; i+=2) {

                this._blocks[i] = this._blocks[i + 1] = LLK.CONTAINER.MENGIMAGES[Math.floor(Math.random() * imgLen)];

            }

        }

        var imgName = "";

        for ( j=0; j < LLK.LEVEL.y; j++) {

            for ( i=0; i < LLK.LEVEL.x; i++) {

                imgName = this.randomArray(this._blocks);

                var temp = new Block(imgName);

                temp.pointX = i;

                temp.pointY = j;

                temp.id = mapIndex;

                LLK.map[temp.id] = temp;

                temp.setAnchorPoint(cc.p(0, 0));

                temp.setPosition(i*60, j*60+30);

                this.addChild(temp);

                mapIndex ++;

            }

        }

        LLK.COUNT = mapIndex;

    },

　　在该方法中，我们根据当前选择的模式随机生成this._blocks数组，记住这里的block是成对出现的。之后我们根据我们的界面的XY层数从我们的this._blocks数组中随机取出元素，取出的元素作为参数初始化Block然后把它添加到Layer中，在生成Block的时候我们要注意给Block的坐标pointX 、pointY赋值，并且使用我们的map数组缓存Block数组，供之后的Block移动查找移动位置的Block使用，最后，我们不要忘记给我们的Block计数附上值。

　　之后在构造方法里我们做了这样一件事，把时间显示label添加到Layer
this._timeLabel = cc.LabelTTF.create("00:00","Arial Bold",16);

this._timeLabel.setPosition(180,520);

this._timeLabel.setColor(cc.c3b(255,255,255));

this.addChild(this._timeLabel,10);
　　接下来就是我们的时间统计了this.schedule(this.scoreCounter, 1);这里每隔一秒调用一下scoreCounter方法，我们来看看这个方法
　　scoreCounter:function () {

        if( this._state == STATE_PLAYING ) {

            this._time++;

            var minute = 0 | (this._time / 60);

            var second = this._time % 60;

            minute = minute > 9 ? minute : "0" + minute;

            second = second > 9 ? second : "0" + second;

            this._timeString = minute + ":" + second;

            this._timeLabel.setString(this._timeString);

//            this._levelManager.loadLevelResource(this._time);

        }

    },

　　当游戏还在运行状态，时间计数每次加1然后转化成相应的时间显示形式之后修改时间显示label的内容。

　　之后，我们还有一个游戏结束的调用方法
　　onGameOver:function () {

        this._state = STATE_GAMEOVER;

        var scene = cc.Scene.create();

        scene.addChild(GameOver.create());

        cc.Director.getInstance().replaceScene(cc.TransitionFade.create(1.2, scene));

    }

它做的是修改游戏的状态并且切换游戏场景。
