cocos2d-x绑定ccb文件

本文主要是介绍cocos2d-x绑定ccb文件，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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;
USING_NS_CC_EXT;class GameScene :public CCLayer
,public CCBMemberVariableAssigner
,public CCNodeLoaderListener
,public CCBSelectorResolver
{
public:virtual bool init();void onEnter();void onExit();static CCScene *scene();CCB_STATIC_NEW_AUTORELEASE_OBJECT_WITH_INIT_METHOD(GameScene, create); //如果此处提示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'；)，当然，这个方法也是可以去掉的，直接用CREATE_FUNC(GameScene)能达到相同的效果。    
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 NewGame(CCObject* sender);void ContinueGame(CCObject* sender);void CloseGame(CCObject* sender);void AboutGame(CCObject* sender);void setAnimationManager(CCBAnimationManager* value);CCLabelTTF* helloLabel;};class GameSceneLoader:public cocos2d::extension::CCLayerLoader{      //这个类也可以完全剥离成一个单独的文件
public:CCB_STATIC_NEW_AUTORELEASE_OBJECT_METHOD(GameSceneLoader, loader);
protected:CCB_VIRTUAL_NEW_AUTORELEASE_CREATECCNODE_METHOD(GameScene);};#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（即使实际的类名是以小写字母开头的，此处仍必须改为大写字母，否则，读取时直接报错，比较符合类名大写的命名规范），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
SEL_MenuHandler GameScene::onResolveCCBCCMenuItemSelector(CCObject * pTarget, const char* pSelectorName)
{CCB_SELECTORRESOLVER_CCMENUITEM_GLUE(this, "NewGame", GameScene::NewGame);CCB_SELECTORRESOLVER_CCMENUITEM_GLUE(this, "CloseGame", GameScene::CloseGame);CCB_SELECTORRESOLVER_CCMENUITEM_GLUE(this, "AboutGame", GameScene::AboutGame);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)
{CCScene *returnback=AboutGameScene::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);   //切换的另一个ccb文件中
}
void GameScene::CloseGame(CCObject *sender)
{helloLabel->setString("CloseButton pressed.");
}
void GameScene::ContinueGame(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();                                                                                                                                CREATE_FUNC(AboutGameScene);   //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：

另外，如果你在实现时，出现黑屏，并且控制台提示Cocos2d: Get data from file(xxx.ccbi) failed!，这种情况产生的原因有以下几种：
