The real entrance to the Cocos Game, demo version implemented in C + +

Starting point for 1.cocos games

In the main function there is a sentence: return ccapplication::sharedapplication ()->run ();

2. After layers of deep discovery, the real entrance: bool Appdelegate::applicationdidfinishlaunching ()

3. Class inheritance diagram:

4. Code implementation:

The Ccapplicationprotocol header file is as follows and the. cpp file is empty

#pragma onceclass  ccapplicationprotocol{public:    /*  Defines a virtual interface for the real entrance to the game */    virtualbool0;};

CCApplication.h

#pragmaOnce#include"CCApplicationProtocol.h"#include<iostream>using namespacestd;classCcapplication: Publicccapplicationprotocol{ Public: Ccapplication (); /*Run Method*/    Virtual intrun (); /*returns a static pointer*/    Staticccapplication*sharedapplication ();protected:    /*static pointers for implementing a singleton*/    StaticCcapplication *sm_psharedapplication;};

CCApplication.cpp

#include"CCApplication.h"/*CPP file, initialize static members*/ccapplication* Ccapplication::sm_psharedapplication =NULL; Ccapplication::ccapplication () {/*assign a child class object to a static pointer to the parent class*/sm_psharedapplication= This;} Ccapplication*ccapplication::sharedapplication () {/*implementing a single case*/    if(Sm_psharedapplication! =NULL)returnsm_psharedapplication;}intCcapplication::run () {/*Call the parent class method to implement the game startup*/applicationdidfinishlaunching (); return 0;}

AppDelegate.h

#pragma once"CCApplication.h"class appdelegate:Private  ccapplication{public:    /* implements the inherited Grandfather class method * /    virtualbool  applicationdidfinishlaunching ();};

AppDelegate.cpp

" AppDelegate.h " /* implemented the inherited Grandfather class method */ BOOL appdelegate::applicationdidfinishlaunching () {    /*Somethint to iniialize the game */       "game start" << Endl;      return true ;}

Test code:

" AppDelegate.h " int Main () {    appdelegate app;    Ccapplication::sharedapplication (),Run ();    System ("pause");     return 0 ;}
