Member function CCScene::node in coco2d-x deprecated, what should I use now?

cocos2d-x C++
#1

In Step by Step Cocos2dxSimpleGame tutorial (Chapter 7 - Some Icing on the Cake), the author uses following code to create game over scene:

GameOverScene *gameOverScene = GameOverScene::node();

which node()is deprecated in cocos2d-x 2.0.1. So I try to replace with following:

GameOverScene *gameOverScene = GameOverScene::create();

but Xcode returns

Cannot initialize a variable of type 'GameOverScene *' with an value of type 'cocos2d::CCScene'

as they declared as different type (node() returns GameOverScene*, while create() returns cocos2d::CCScene).

So, what should I use to replace node()? Is create() the right way or I should use other function?

Yes, you should use create.
The same as node, subclass should implement its own create.

Thanks Minggo, but can you specify how to use it?

I’ve tried:

GameOverScene *gameOverScene = GameOverScene::create();

XCode compile with error as GameOverScene::create() returns cocos2dx::CCScene instead of GameOverScene as node() did. I also tried:

GameOverScene *gameOverScene = (GameOverScene *) GameOverScene::create();

This time, Xcode compile successfully, but when run on a iPhone simulator, it return fail when access line right after create (i.e. gameOverScene->getLayer()->……).

Did you implement GameOverScene::create()?

I see, problem solved, thanks Minggo.

Just in case if anyone like to know how to implement, below are the details:

in GameOverScene.h, add following line inside class GameOverScene

static GameOverScene *create(void);

in GameOverScene.cpp, add new function create

GameOverScene *GameOverScene::create()
{
    GameOverScene *pRet = new GameOverScene();
    if (pRet && pRet->init())
    {
        pRet->autorelease();
        return pRet;
    }
    else
    {
        CC_SAFE_DELETE(pRet);
        return NULL;
    }
}

Finally, in HelloWorldScene, when declare gameOverScene, instead of using GameOverScene::node(), use the following:

GameOverScene *gameOverScene = GameOverScene::create();

Done. and similar approach also applied to GameOverLayer.

Use LAYER_CREATE_FUNC(myScene) instead of LAYER_NODE_FUNC(myScene) in youre header
