cocos2d 场景切换 unreferenced!!!!错误

概述上一篇解释了如何编译成功HelloCpp，现在说一下场景切换，如何使用按钮，进行场景切换！！！（代码量没多少，书上有一步也没有说明，害死人啊，一下午就这么没了！！！）笔者想练习下场景切换。现在说下，GameScene.h文件GameScene.cpp文件当中其代码如下： GameScene.h文件如下： #ifndef __GAMASCENE__H#define __GAMASCENE__H

上一篇解释了如何编译成功HelloCpp，现在说一下场景切换，如何使用按钮，进行场景切换！！！（代码量没多少，书上有一步也没有说明，害死人啊，一下午就这么没了！！！）笔者想练习下场景切换。现在说下，GameScene.h文件GameScene.cpp文件当中其代码如下：

GameScene.h文件如下：

#ifndef __GAMASCENE__H#define __GAMASCENE__H#include "cocos2d.h"class CGameScene : public cocos2d::cclayer{public:    // Here's a difference. Method 'init' in cocos2d-x returns bool,instead of returning 'ID' in cocos2d-iphone    virtual bool init();    // there's no 'ID' in cpp,so we recommend returning the class instance pointer    static cocos2d::CCScene* scene();    // a selector callback   // voID menuCloseCallback(CCObject* pSender);    // implement the "static node()" method manually    CREATE_FUNC(CGameScene);};#endif // __HELLOWORLD_SCENE_H__

GameScene.cpp文件如下：

#include "GameScene.h"#include "AppMacros.h"USING_NS_CC; CCScene* CGameScene::scene(){	 // 'scene' is an autorelease object	    CCScene *scene = CCScene::create();	    // 'layer' is an autorelease object	    CGameScene *layer = CGameScene::create();	    // add layer as a child to scene	    scene->addChild(layer);	    // return the scene	    return scene;}bool CGameScene::init(){	if(!cclayer::init())	{		return false;	}	CCSize visibleSize=CCDirector::sharedDirector()->getVisibleSize();    CCPoint origin=CCDirector::sharedDirector()->getVisibleOrigin();    cclabelTTF*pLabel=cclabelTTF::create("周建业的游戏","Arial",Title_Font_SIZE);    pLabel->setposition(ccp(origin.x+visibleSize.wIDth/2,origin.y+visibleSize.height-pLabel->getContentSize().height));    this->addChild(pLabel,1);    CCSprite* pSprite=::CCSprite::create("new.jpg");    pSprite->setposition(ccp(visibleSize.wIDth/2 + origin.x,visibleSize.height/2 + origin.y));      // add the sprite as a child to this layer    this->addChild(pSprite,0);    return true;}

这个代码经过笔者无数次检测都没有问题，但是一直出现下述错误

D:/AndroID/androID-ndk-r9d-windows-x86/androID-ndk-r9d/toolchains/arm-linux-androIDeabi-4.6/prebuilt/windows/bin/../lib/gcc/arm-linux-androIDeabi/4.6/../../../../arm-linux-androIDeabi/bin/ld.exe: ./obj/local/armeabI/ObJs/hellocpp_shared/__/__/Classes/HelloWorldScene.o: in function HelloWorld::menuCloseCallback(cocos2d::CCObject*):jni/../../Classes/HelloWorldScene.cpp:100: error: undefined reference to 'CGameScene::scene()'
collect2: ld returned 1 exit status
make.exe: *** [obj/local/armeabi/libhellocpp.so] Error 1

原来到最后还需要修改AndroID.mk文件，该文件中有了编译选项，在里面的

LOCAL_SRCS中添加我们自行添加的GameScene.cpp文件

LOCAL_SRC_fileS := hellocpp/main.cpp \ ../../Classes/AppDelegate.cpp \ ../../Classes/HelloWorldScene.cpp \ ../../Classes/GameScene.cpp \
