HelloWorld::init() does not get called when HelloWorld::createWithPhysics() is called.

[Rubonnek]

• cocos2d-x version: latest git repository as of December 31, 2016
• devices test on: Linux, Mac
• developing environments
  • Mac Xcode version: 8.2
  • Linux GCC: 6.2.1

Steps to Reproduce:

1. Create a new CPP sample project:

cocos new -l cpp inittest

2. Change line 8 from HelloWorldScene.cpp to:

    return HelloWorld::createWithPhysics();

3. Compile

#Linux
cocos run -p linux

#Mac
cocos run -p mac

4. Nothing in the scene will show up. HelloWorld::init() is not getting called.

The problem lies in lines 41 through 56 of CCPlatformMacros.h. Doing the changes I stated above to HelloWorldScene.cpp avoids running the create() function created by the CREATE_FUNC macro which also avoids running the HelloWorld::init() method.

Changing line 8 of HelloWorldScene.cpp to the following:

auto scene = HelloWorld::create();
scene->initWithPhysics();
return scene;

fixes this issue temporarily.

The only problem I see with doing this is that Scene::init() and Scene::initWithPhysics() overlap in functionality and incurs in a small unnecessary overhead. There's no need to call both of these functions.

Just noticed that the proper way of initiating a scene with physics now is to change line 16 of HelloWorldScene.cpp to the following:

    if ( !Scene::initWithPhysics() )

Omg you solved my problem thank you.
