  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
用cocos2d-html5做的消除类游戏《英雄爱消除》(3)——游戏主界面
  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
用cocos2d-html5做的消除类游戏《英雄爱消除》(3)——游戏主界面
  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);
        }
    },
用cocos2d-html5做的消除类游戏《英雄爱消除》(3)——游戏主界面

  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。
