Introduction to Cocos2d-x (1) Making a dynamic Sprite

Principle:

Cocos2d has a director to control the whole game process, the director will add the scene to the screen, the scene has a variety of actors.

First by showing a picture to see the cocos2d game process:

AppDelegate.cpp

BOOL Appdelegate::applicationdidfinishlaunching ()  
{  
    //Initialize director  
    Ccdirector *pdirector = ccdirector:: Shareddirector ();  
    Pdirector->setopenglview (Cceglview::sharedopenglview ());  
      
    Open fps  
    pdirector->setdisplaystats (true);  
      
    Set fps the ' default value is 1.0/60 if/don ' t call this  
    pdirector->setanimationinterval (1.0/60);  
      
    Create a scene  
    ccscene *pscene = Gamescence::scene ();  
      
    Run this scene  
    Pdirector->runwithscene (pscene);  
    return true;  
}

The above code adds a scene gamescence, and here's a look at the concrete implementation:

GameScence.h

#include "cocos2d.h"  
#include "box2d/box2d.h"  
      
class Gamescence:public Cocos2d::cclayer  
{public  
:  
    BOOL Init ();  
    You must override the scene ()  
    static cocos2d::ccscene* scene ();  
    Equivalent to the CREATE function, is to rewrite the CREATE function in the Cclayer  
    Create_func (gamescence);  

GameScence.cpp

#include "GameScene.h"  
      
using namespace cocos2d;  
      
ccscene* Gamescence::scene ()  
{  
    ccscene * scene = NULL;  
    Do
    {  
        scene=ccscene::create ();  
      
        gamescence* gamescene=gamescence::create ();  
        Scene->addchild (Gamescene);  
    } while (0);  
      
    return scene;  
};  
      
BOOL Gamescence::init ()  
{  
    bool BRet = false;  
    Do
    {  
        //Create a sprite from the picture  
        ccsprite* psprite = ccsprite::create ("Bg.png");  
        Gets the screen size  
        ccsize size = Ccdirector::shareddirector ()->getwinsize ();  
        Sets the position of the sprite in the scene, coordinates from the lower left corner of the 0,0  
        psprite->setposition (CCP (SIZE.WIDTH/2, SIZE.HEIGHT/2));  
        Add Sprite to Scene  
        This->addchild (psprite, 0);  
    } while (0);  
      
    Bret=true;  
      
    return bRet;  
};
