MenuItemToggle, I don’t even know what that is. What if I have to pass a custom class instance? Not some menuitem thing.

what are you trying to share

I’m creating a player(name, score) instance in scene 1, which must be available in scene 2 also.

try using userdefault to store data

Well that’s an option too though. But can you store objects there like key-value pairs? Or just simple string, int etc.

simple data like string and integers

Well that’s not good enough.

But is it possible to pass parameters in the scene constructor? 

auto scene = GameScene::createScene(“something goes here”);

I thought you was using cocos2d-JS not cocos2d-x C++

Sorry about that, I’m using JS I just wanted to write an example. 

i know how to do it in cocos2d-x C++

Would you mind sharing it? :D

Scene to receive variable header

static cocos2d::Scene *createScene( int phaseNumberTemp, int levelNumberTemp );

Scene to receive variable implementation

// the world and level number
int phaseNumberGS;
int levelNumberGS;

Scene *GameScene::createScene( int phaseNumberTemp, int levelNumberTemp )
{
    // store world and level number
    phaseNumberGS = phaseNumberTemp;
    levelNumberGS = levelNumberTemp;
    
    // 'scene' is an autorelease object
    auto scene = Scene::createWithPhysics();
    
    scene->getPhysicsWorld( )->setDebugDrawMask( PhysicsWorld::DEBUGDRAW_ALL );
    
    // 'layer' is an autorelease object
    auto layer = GameScene::create();
    layer->setPhysicsWorld(scene->getPhysicsWorld());

    // add layer as a child to scene
    scene->addChild(layer);

    // return the scene
    return scene;
}

Calling the scene and passing parameters

// go to settings scene
Scene *scene = GameScene::createScene( 1, 2  );
    
Director::getInstance( )->replaceScene( TransitionFade::create( 1.0, scene ) );

I managed to do it like this:

var Scene1Layer = cc.LayerColor.extend({
    ctor:function()
    {
        this._super();
        
        var player = new Player("Player1", 100);
        
        this.goToScene2(player);
        
        return true;
    },
    goToScene2: function(player)
    {
        var scene = new Scene2Scene(player);
        
        cc.director.runScene(scene);
    }
});

var Scene2Scene = cc.Scene.extend({
    onEnter:function()
    {
        this._super();

        if (SCENE2_INIT == false)
        {
            SCENE2_INIT = true;

            var layer = new Scene2Layer();

            this.addChild(layer);
        }
    },
    ctor:function(player)
    {
        this._super();
        
        cc.log(player.age);
    
        return true;
    }
});

Fantastic, hope others can benefit from your knowledge

Also got this solution which is very similar to yours 

Scene1

var Scene1 = cc.Scene.extend(
{
    ctor:function ()
	{
		this._super();
		this.init();
	},

	init:function ()
	{
        var size = cc.winSize;
        // add a "close" icon to exit the progress. it's an autorelease object
        var closeItem = new cc.MenuItemImage(
            res.CloseNormal_png,
            res.CloseSelected_png,
            function () {
                var scene = new Scene2(5, 78.6);
                cc.director.replaceScene(scene);
            }, this);
        closeItem.attr({
            x: size.width - 20,
            y: 20,
            anchorX: 0.5,
            anchorY: 0.5
        });
        var menu = new cc.Menu(closeItem);
        menu.x = 0;
        menu.y = 0;
        this.addChild(menu, 1);
	}
});

Scene2

var Scene2 = cc.Scene.extend(
{
    ctor:function (var1, var2)
	{
		this._super();
		this.init(var1, var2);
	},

	init:function (var1, var2)
	{
        var size = cc.winSize;

        var helloLabel = new cc.LabelTTF("Hello World", "Arial", 38);
        helloLabel.x = size.width / 2;
        helloLabel.y = size.height / 2;
        this.addChild(helloLabel, 5);

        cc.log("Var 1: " + var1);
        cc.log("Var 2: " + var2);
	}
});

This is how I do actually :D I just don’t use the init though. Isn’t that something that just remained in cocos2d-x from cocos2d? With ctor added I don’t really find it useful anymore.

True not needed :D
