ccc 多点触控2

经过不断的思考发现，如果是两个sprite都添加触控的时候，往往直接成单点触控，
但是如果是两个node的时候在node上面点击就会变成多点触控的形式

cc.Class({
    extends: cc.Component,

    properties: {
        isAPress:false,
        aLabel:
        {
            default:null,
            type   :cc.Label
        }
    },

    // use this for initialization
    onLoad: function () {

        this.isAPress=false

        this.registerInput();

    },

    registerInput:function()
    {
        var self=this

        cc.eventManager.addListener({
            event: cc.EventListener.TOUCH_ONE_BY_ONE,

            //开始
            onTouchBegan: function(touch, event) {

                let touchPos=touch.getLocation()
                if(touchPos.x<480)
                {
                    self.isAPress=true
                }
                return true; // don't capture event
            },

            //移动
            onTouchMoved: function(touch, event) {
                let touchPos=touch.getLocation()
                if(touchPos.x<480)
                {
                    self.isAPress=true
                }
            },

            //结束
            onTouchEnded: function(touch, event) {
                self.isAPress=false
            }
        }, self.node);
    },

    update:function()
    {
        if(this.isAPress)
        {
            this.aLabel.string = "1"
        }
        else
        {
            this.aLabel.string = "0"
        }
    },

});
