Invoke other Layers functions

cocos2d-x JavaScript
#1

Hello… i’m having an issue trying to invoke functions in other layers.
I’m on the PlayScene.js and i want to invoke the function addPoints which i have in StatusLayer.js bu i can’t.
i tried statusLayer.addPoint(); but it seems not to work.
Any suggestions?
Thnks

Sorry, we can’t help you with your own implementation unless you give us some code of PlayScene and StatusLayer

Sorry… here i add my code

var PlayScene = cc.Layer.extend({
    animationLayer:null,
    statusLayer:null,


    onEnter:function(){
        this._super();

        //add 3 layers in the right order
        this.addChild(new BackgroundLayer(), 0, TagOfLayer.background);
        this.addChild(new AnimationLayer(),0, TagOfLayer.Animation );
        this.addChild(new StatusLayer(),0, TagOfLayer.Status);
        this.animationLayer = this.getChildByTag(TagOfLayer.Animation);
        this.statusLayer = this.getChildByTag(TagOfLayer.Status);

        this.animationLayer.createPlayer();
        this.animationLayer.startCreatingEnemies();
        this.animationLayer.startCheckCollision(this);
    },

    checkCollision:function(){
        if(this.enemy[this.f] != null && this.enemyAction[this.f].isDone()){

            //console.log("enemy: " + parseInt(this.enemy[this.f].getPosition().x));
            //console.log("player: " + this.player.getPosition().x);
            if(this.enemy[this.f].getType() == this.player.getType()){
                console.log("vivio");
                this.statusLayer.addPoint();
                this.f++;
                //console.log("i: " + this.i + " f: " + this.f);
            }
            else{
                console.log("murio");

                this.f++;
                //console.log("i: " + this.i + " f: " + this.f);
            }
        }
        else{
            //console.log("nulooo");
        }


    },



});

var StatusLayer = cc.Layer.extend({

    lblPoints:null,
    points:0,

    ctor:function(){
        this._super();
        this.init();
    },

    init:function(){
        this._super();
        var winSize = cc.Director.getInstance().getWinSize();
        this.lblPoints = cc.LabelTTF.create("Coins:0", "Helvetica", 20);
        this.lblPoints.setColor(cc.c3(0,0,0));
        this.lblPoints.setPosition(cc.p(winSize.width - (winSize.width - 50), winSize.height - 20));
        this.addChild(this.lblPoints);
    },

    addPoint:function(){
        this.points++;
        this.lblPoints.setString(this.points);
    }



});

I’m trying to follow the tutorail of parkour on javascript and tried the TagOfLayer but to be honest i don’t know very well how it works so it do not work for me jaja…

Hope this helps you to help me jeje…

Thanks

Have you used Chrome developer tool to inspect your code and add break point in checkCollision function ? You can verify

  1. StatusLayer === undefined
  2. this.statusLayer instanceof StatusLayer
  3. Step into addPoint function to see if it really get called.
  4. If all these tests get through, you can maybe step into setString to see whether the string in LabelTTF is correctly set.
