cocos2dx一个场景添加多个层

首先创建两个layer，以下是头文件

#pragma once
#include "cocos2d.h"
USING_NS_CC;
class BackgroundLayer : public cocos2d::CCLayer
{
public:
virtual bool init();
CREATE_FUNC(BackgroundLayer);
};

#pragma once
#include "cocos2d.h"
USING_NS_CC;
class FishLayer : public cocos2d::CCLayer
{
public:
virtual bool init();
CREATE_FUNC(FishLayer);
};

 

现在去源文件实现一下：

#include "BackgroundLayer.h"
bool BackgroundLayer::init()
{
CCSprite* bg = CCSprite::create("bg.png");
bg->setPosition(ccp(visiblesize.width/2, visiblesize.height/2));
addChild(bg);
return true;
}

#include "FishLayer.h"
bool FishLayer::init()
{
CCSprite* bg = CCSprite::create("bgfish.png");
bg->setPosition(ccp(visiblesize.width/2, visiblesize.height/2));
addChild(bg);
return true;
}

ok，现在已经有了两个层了，建一个scene并添加他们：

#pragma once
#include "cocos2d.h"
#include "FishLayer.h"
#include "BackgroundLayer.h"
class GameScene : public cocos2d::CCScene
{
public:
virtual bool init();
static CCScene* playGame();
};

去源文件添加啦：

#include "GameScene.h"
CCScene* GameScene::playGame()
{
GameScene* scene = new GameScene();
scene->init();
return scene;
}
bool GameScene::init()
{
BackgroundLayer* pLayer_bg = BackgroundLayer::create();
FishLayer* pLayer_fish = FishLayer::create();
addChild(pLayer_bg);
addChild(pLayer_fish);
return true;
}

ok，现在场景里面已经有两个层了，可以分别在这两个层里添加东西了。
