cocos2d-x绑定ccb文件

首先，ccb文件是如何生成的，我就不多说了，大家可以搜下cocosbuilder，就能找的相关的教程，而通过cocosbuilder，我们可以省去了很多设计的麻烦，比如设计一个精灵的位置啥的，而通过cocosbuilder，我们可以把我们编码的重点放到具体的控制类上面，而不是在显示页面上下很大的功夫。闲话不多说，要想实现这些好处，首先确定你的Cocos2d-x的版本号，如果是2.0.4，那就用cocosbuilder 2.1吧（当然，cocosbuilder只有mac版的，如果是windows，那就用cocostudio吧），如果cocos2d-x是2.1以上版本，就用cocosbuilder3.0以上版本吧，比如我用的是cocos2d-x2.1.4，我的cocosbuilder为3.0.4。

首先，来看下绑定代码吧（GameScene.h）

#ifndef __loading__GameScene__

#define __loading__GameScene__

#include <iostream>

#include "cocos2d.h"

#include "cocos-ext.h"

USING_NS_CC_EXT;

class GameScene :public CCLayer

,public CCBMemberVariableAssigner

,public CCBSelectorResolver

{

public:

    virtual bool init();

    void onEnter();

    void onExit();

    static CCScene *scene();

    CCB_STATIC_NEW_AUTORELEASE_OBJECT_WITH_INIT_METHOD(GameScene, create); //如果此次提示GameScene有错误，要么是下面的虚函数没有重写完，要么是重写的方法中参数有误（例如：Allocating an object of abstract class type 'GameScene'；)

    virtual bool onAssignCCBMemberVariable(CCObject* pTarget, const char* pMemberVariableName, CCNode* pNode);

    virtual void onNodeLoaded(CCNode * pNode, CCNodeLoader * pNodeLoader);

#endif /* defined(__loading__GameScene__) */

GameScene.cpp文件：

#include "GameScene.h"

#include "AboutGameScene.h"

bool GameScene::init()

{

    if(!CCLayer::init())

    {

        return false;

    }

    return true;

}

void GameScene::onEnter()

{

    CCLayer::onEnter();

}

void GameScene::onExit()

{

    CCLayer::onExit();

}

CCScene* GameScene::scene()

{

    CCScene* scene = CCScene::create();

    CCNodeLoaderLibrary* lib = CCNodeLoaderLibrary::newDefaultCCNodeLoaderLibrary();

    lib->registerCCNodeLoader("GameScene", GameSceneLoader::loader());//要绑定的类名，注册文件

    CCBReader* reader = new CCBReader(lib);

    CCNode* node = reader->readNodeGraphFromFile("TestGameScene.ccbi",scene);   //要读取的文件名，当前对象

    reader->release();                                       //记得要释放

    if (NULL!=node) {

        scene->addChild(node);

    }

    return scene;

}

// 将变量名字与变量做映射

bool GameScene::onAssignCCBMemberVariable(cocos2d::CCObject *pTarget, const char *pMemberVariableName, cocos2d::CCNode *pNode){

    CCB_MEMBERVARIABLEASSIGNER_GLUE(this, "helloLabel", CCLabelTTF*, helloLabel);

    return true;

}

// 当此场景加载完成后，如果需要做一些操作，则在此方法中添加

void GameScene::onNodeLoaded(cocos2d::CCNode *pNode, cocos2d::extension::CCNodeLoader *pNodeLoader){

    helloLabel->setString("hello cocosbuilder");

}

//将menu与具体的函数绑定

    CCB_SELECTORRESOLVER_CCMENUITEM_GLUE(this, "ContinueGame", GameScene::ContinueGame);

    return NULL;

}

// 将CCControl名字与响应函数做映射，也就是通过cocosbuilder中的Control（cccontrolbutton）创建的对象

SEL_CCControlHandler GameScene::onResolveCCBCCControlSelector(CCObject * pTarget, const char* pSelectorName){

    //CCB_SELECTORRESOLVER_CCCONTROL_GLUE(this, "onPressButton", MainScene::onPressButton);

    return NULL;

}

void GameScene::NewGame(CCObject *sender)

{

    helloLabel->setString("NewButton pressed.");

}

void GameScene::AboutGame(CCObject *sender)

}

{

    helloLabel->setString("ContinueButton pressed.");

}

//如果ccb文件中有动画，那就在这里设置控制吧

void GameScene::setAnimationManager(cocos2d::extension::CCBAnimationManager *value){

}

另一个绑定AboutGameSceneLoader.h代码

#ifndef loading_AboutGameSceneLoader_h

#define loading_AboutGameSceneLoader_h

#include "AboutGameScene.h"

class AboutGameSceneLoader:public cocos2d::extension::CCLayerLoader{

public:

    CCB_STATIC_NEW_AUTORELEASE_OBJECT_METHOD(AboutGameSceneLoader, loader);

protected:

    CCB_VIRTUAL_NEW_AUTORELEASE_CREATECCNODE_METHOD(AboutGameScene);};

#endif

AboutGameScene.h代码：

#include <iostream>

#include "cocos2d.h"

#include "cocos-ext.h"

USING_NS_CC;

USING_NS_CC_EXT;

class AboutGameScene :public CCLayer

,public CCBMemberVariableAssigner

,public CCNodeLoaderListener

,public CCBSelectorResolver

{

public:

    bool init();

    void onEnter();

    void onExit();

    static CCScene *scene();

    CCB_STATIC_NEW_AUTORELEASE_OBJECT_WITH_INIT_METHOD(AboutGameScene, create);

    virtual bool onAssignCCBMemberVariable(CCObject* pTarget, const char* pMemberVariableName, CCNode* pNode);

    virtual void onNodeLoaded(CCNode * pNode, CCNodeLoader * pNodeLoader);

    virtual SEL_MenuHandler onResolveCCBCCMenuItemSelector(CCObject * pTarget, const char* pSelectorName);

    virtual SEL_CCControlHandler onResolveCCBCCControlSelector(CCObject * pTarget, const char* pSelectorName);

    void backMenu(CCObject* sender);

    void setAnimationManager(CCBAnimationManager* value);

    CCLabelTTF* helloLabel;

};

AboutGameScene.cpp代码：

#include "AboutGameScene.h"

#include "GameScene.h"

#include "AboutGameSceneLoader.h"

bool AboutGameScene::init()

{

    if(!CCLayer::init())

    {

        return false;

    }

    return true;

}

void AboutGameScene::onEnter()

{

    CCLayer::onEnter();

}

void AboutGameScene::onExit()

{

    CCLayer::onExit();

}

CCScene* AboutGameScene::scene()

{

    CCScene* scene = CCScene::create();

    CCNodeLoaderLibrary* lib = CCNodeLoaderLibrary::newDefaultCCNodeLoaderLibrary();

    lib->registerCCNodeLoader("AboutGame", AboutGameSceneLoader::loader());

    CCBReader* reader = new CCBReader(lib);

    CCNode* node = reader->readNodeGraphFromFile("AboutGameScene.ccbi",scene);

    reader->release();

    if (NULL!=node) {

        scene->addChild(node);

    }

    return scene;

}

bool AboutGameScene::onAssignCCBMemberVariable(cocos2d::CCObject *pTarget, const char *pMemberVariableName, cocos2d::CCNode *pNode){

    return true;

}

void AboutGameScene::onNodeLoaded(cocos2d::CCNode *pNode, cocos2d::extension::CCNodeLoader *pNodeLoader){

    CCSize size=CCDirector::sharedDirector()->getWinSize();

    CCSprite *mainsprite=CCSprite::create("catBody1.png");

    addChild(mainsprite,1);

    CCAnimation *animation=CCAnimation::create();

    animation->addSpriteFrameWithFileName("catBody1.png");

    animation->addSpriteFrameWithFileName("catBody2-4.png");

    animation->addSpriteFrameWithFileName("catBody3.png");

    animation->addSpriteFrameWithFileName("catBody2-4.png");

    animation->setDelayPerUnit(0.1f);//设置动画的间隔时间

    animation->setRestoreOriginalFrame(true);//是否返回第一帧

    mainsprite->runAction(CCRepeatForever::create(CCAnimate::create(animation)));

    mainsprite->setPosition(ccp(size.width/4, size.height/3));

}

SEL_MenuHandler AboutGameScene::onResolveCCBCCMenuItemSelector(CCObject * pTarget, const char* pSelectorName)

{

    CCB_SELECTORRESOLVER_CCMENUITEM_GLUE(this, "backMenu", AboutGameScene::backMenu);

    return NULL;

}

SEL_CCControlHandler AboutGameScene::onResolveCCBCCControlSelector(CCObject * pTarget, const char* pSelectorName){

    return NULL;

}

void AboutGameScene::backMenu(CCObject *sender)

{

    CCScene *returnback=GameScene::scene();   //要切换到的场景

    CCDirector::sharedDirector()->setDepthTest(true); //开启深度检测

    CCTransitionScene *tmpaction=CCTransitionMoveInR::create(1.2,returnback);  //切换方法

    CCDirector::sharedDirector()->replaceScene(tmpaction);

}

void AboutGameScene::setAnimationManager(cocos2d::extension::CCBAnimationManager *value){

}

这些代码和以上的功能相同，贴出来只是让你进一步了解。

最后的实现效果：
