cocos2d-js开发过程笔记

function resourceCallBack(){
    cc.game.onStart = function(){
        cc.view.adjustViewPort(true);//是否自动添加viewport
        if(thisismobile){
            cc.view.setDesignResolutionSize(640, 1136, cc.ResolutionPolicy.EXACT_FIT);
        }else{
            cc.view.setDesignResolutionSize(640, 1136, cc.ResolutionPolicy.SHOW_ALL);
        }
        cc.view.enableAutoFullScreen(false);//是否自动全屏 最好放置于下行前
        cc.view.resizeWithBrowserSize(false);//根据浏览器窗口改变
        //load resources
        MyLoaderScene.preload(g_resources, function () {
            cc.director.runScene(new gameScene());
        }, this);
    };
    cc.game.run("gameCanvas");
}

var _frames = [];
for(var i = 0; i < 5; i++){
    var frame = new cc.SpriteFrame(this.texture,cc.rect(356 * i, 0, 356, 209));
    _frames.push(frame);
}
var _Animation = new cc.Animation(_frames, 0.01);
_Animation.setRestoreOriginalFrame(true);
// var _Animate = cc.Animate.create(_Animation).repeatForever();
var _Animate = cc.Animate.create(_Animation);
this.runAction(_Animate);

layer 此类默认设置锚点无效
须加上 this.ignoreAnchorPointForPosition(flase);

// 在第二种情况下，alpha不生效
var shareLayer = cc.LayerColor.extend({
	name : "shareLayer",
	ctor : function(){
                // 1.
		this._super(cc.color(0, 0, 0, 125));

               // 2.
              // this.color = cc.color(0,0,0,125);
	}
});

这里要把swallowTouches设置为true，这样onTouchBegan返回true才能够吞噬触摸，不继续往优先级更低的层传递，从而实现遮挡层。所以 onTouchDispose处理方法不能在onTouchBegan  !!! 返回true之前!!!执行。
   loadListener : function(){
        var listener = cc.EventListener.create({
            event           : cc.EventListener.TOUCH_ONE_BY_ONE,
            target          : this,
            swallowTouches  : true,
            onTouchBegan    : this.onTouchBegan,
            onTouchMoved    : this.onTouchMoved,
            onTouchEnded    : this.onTouchEnded
        });
        cc.eventManager.addListener(listener, this);
    },
    onTouchBegan: function (touch, event) {
        var self = this.target;
        var locationInNode = self.convertToNodeSpace(touch.getLocation());
        var size = self.getContentSize();
        var rect = cc.rect(0, 0, size.width, size.height);
        if (!cc.rectContainsPoint(rect, locationInNode)) {
            return false;
        }
        return true;

    },
    onTouchMoved : function (touch, event) {
        var self = this.target;
    },
    onTouchEnded : function (touch, event) {
        var self = this.target;

        // 触摸处理
        self.onTouchDispose();
    },
    onTouchDispose : function(){
        // TODO...
    }

//layer 节点 徐设置这个为ture下方可用cc.fadeOut();
this.setCascadeOpacityEnabled(true);
