I just made simple Cocos2d-x project.
It has serveral scenes and everyone has it’s own JavaScript.

dashboard.js

const MyClass = cc.Class.extend({

    ...

    update: function() {
        this.remainTimes --;
    },

    // Call the schedule method in your class constructor or init method
    ctor: function() {
        // Schedule the update function to be called every frame
        this.schedule(this.update().bind(this), 1);
        label.setFontFillColor(this.remainTimes);
        cc.log('remainTimes : ', this.remainTimes);
    };
});

here is console logs:

remainTimes : 10
remainTimes : 9
remainTimes : 8
remainTimes : 7
...

But Label’s text is like 10 after 1s 8 and after 1s 6 …
I am looking for if this dashboard.js is called twice in dashboard.scene but nothing!

Sometimes it works corretly but sometimes it works wrong….
Why?

I solve this problom and want to show correct remain time.
