How to get value from scene which i have pass from other scene in cocos2d for android?

Question

I have PlayScene.cpp in this scene i have pass value like this: CCDirector::sharedDirector()->replaceScene( CCTransitionPageTurn::create(1.0f, ZeroScene::scene(3), true));

Now value is three (ZeroScene::scene(3)) and am able to get this value in ZeroScene

CCScene* ZeroScene::scene(int pups) { CCLog("selected pup is : %i",pups);

    // 'scene' is an autorelease object
CCScene *scene = CCScene::create();

// 'layer' is an autorelease object
ZeroScene *layer = ZeroScene::create();

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

// return the scene
return scene;

}

Now i want to use this int pups value in ZeroScene.cpp class. Please help me someone. Thanks in advance.

You have to write your own create function which will take this argument. Here is an example :

In your *.h file add :

static ZeroScene* create(int pups);

And in your *.cpp :

ZeroScene* ZeroScene::create(int pups) {

    ZeroScene *zs = new ZeroScene();

    if (zs->init()) {
        zs->autorelease();
        //here write your code to initialize everything
    } else
        zs = NULL;

    return zs;

}

Then you simply change the create line in scene() method. Everything that I wrote here is basic cocos2d-x initialization.
