Cocos2d-x 3.0 创建一个场景，并设置现场的时候，项目开始执行上主动

头

#ifndef __TEST_H__

#define __TEST_H__





#include "cocos2d.h"

USING_NS_CC;





class Test : public Layer

{

public: //不要忘记public不然默觉得private的不能正常执行

static Scene * createScene();

virtual bool init();

CREATE_FUNC(Test);

};

#endif //__TEST_H__

源文件

#include "Test.h"

USING_NS_CC;





Scene * Test::createScene()

{

auto scene = Scene::create();

auto layer = Test::create();

scene->addChild(layer);

return scene;

}

bool Test::init()

{

if (!Layer::init())

{

return false;

}





Size visibleSize = Director::getInstance()->getVisibleSize();

Vec2 origin = Director::getInstance()->getVisibleOrigin();





auto label = LabelTTF::create("Hello World", "Arial", 24);

label->setPosition(Vec2(origin.x + visibleSize.width/2,origin.y + visibleSize.height - label ->getContentSize().height));

this->addChild(label, 1);

return true;

}

然后在AppDelegate.cpp中。加入头文件

#include "AppDelegate.h"

#include "HelloWorldScene.h"

#include "Test.h"  //加入头文件





USING_NS_CC;





AppDelegate::AppDelegate() {





}





AppDelegate::~AppDelegate() 

{

}





bool AppDelegate::applicationDidFinishLaunching() {

    // initialize director

    auto director = Director::getInstance();

    auto glview = director->getOpenGLView();

    if(!glview) {

        glview = GLView::create("My Game");

        director->setOpenGLView(glview);

    }





    // turn on display FPS

    director->setDisplayStats(true);





    // set FPS. the default value is 1.0/60 if you don't call this

    director->setAnimationInterval(1.0 / 60);





    // create a scene. it's an autorelease object

    //auto scene = HelloWorld::createScene();

auto scene = Test::createScene();  //实例化场景





    // run

    director->runWithScene(scene); //把实例化的场景名加进来就能够了





    return true;

}





// This function will be called when the app is inactive. When comes a phone call,it's be invoked too

void AppDelegate::applicationDidEnterBackground() {

    Director::getInstance()->stopAnimation();





    // if you use SimpleAudioEngine, it must be pause

    // SimpleAudioEngine::getInstance()->pauseBackgroundMusic();

}





// this function will be called when the app is active again

void AppDelegate::applicationWillEnterForeground() {

    Director::getInstance()->startAnimation();





    // if you use SimpleAudioEngine, it must resume here

    // SimpleAudioEngine::getInstance()->resumeBackgroundMusic();

}
