Question

I can not make a call to a method of a class from another class :rewrite the code cocos2d (objective-c) on cocos2d-x (c++)

In the IronMan.h you have to declare

static void playClicked();

In the Avenger.cpp you can use this method

 CCSize *screenSize   = CCDirector::sharedDirector()->getVisibleSize();
CCPoint pointOrigin  = CCDirector::sharedDirector()->getVisibleOrigin();
float x = screenSize.width;
float y = screenSize.height;*

CCWidgetLayout* widgetLayout = CCWidgetLayout::create();

addChild(widgetLayout);

CCButton* playButton = CCButton::create("btn1.png", "btn2.png", "btn3.png");
playButton->setPosition(x/1.2f,y/1.5f);
playButton->setClickSelector(this,click_selector(IronMan::playClicked));
widgetLayout->addChild(playButton,1);
