cocos2dx使用版本：cocos2dx3.2   IDE:使用VS2013

下载游戏引擎自不用说了。

使用命令行创建项目。

cocos new GeDou -p com.zhenqi.game -l cpp -d F:\cocos2d-xProject

而后使用vs2013打开，并创建一个加载层。

LoadingScene.h 内容如下：
#ifndef __LOADING_SCENE_H__
#define __LOADING_SCENE_H__
#include "ui/CocosGUI.h"
#include "cocos2d.h"
USING_NS_CC;
class Loading : public Layer
{
public:
static Scene* createScene();
virtual bool init();
//设置进度条
void SetPro(float fRate);
//资源预加载
void LoadRec();
//资源预加载回调函数
void OnLoadArmatureData(float percent);
//资源加载回调
void OnLoadRecCallBack(Object *pObj);
    CREATE_FUNC(Loading);
protected:
intm_nLoadRecNum;//资源加载数
intm_nLoadRecTotalNum;//资源加载总数
ui::LoadingBar* pProLoadRec;    //进度条
};
#endif // __LOADING_SCENE_H__

LoadingScene.cpp 实现类如下：

#include "LoadingScene.h"
#include "ChooseHero.h"
#include "ui/CocosGUI.h"
#include "cocostudio/CocoStudio.h"
using namespace cocostudio;
Scene* Loading::createScene()
{
    // 'scene' is an autorelease object
    auto scene = Scene::create();
    
    // 'layer' is an autorelease object
    auto layer = Loading::create();
    // add layer as a child to scene
    scene->addChild(layer);
    // return the scene
    return scene;
}
bool Loading::init()
{
    if ( !Layer::init() )
    {
        return false;
    }
    
    Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();
Size size = Director::getInstance()->getWinSize();
