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"

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()
{

}
CCScene* GameScene::scene()
{
CCScene* scene = CCScene::create();
CCNodeLoaderLibrary* lib = CCNodeLoaderLibrary::newDefaultCCNodeLoaderLibrary();

if (NULL!=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){

// 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

}
//将menu与具体的函数绑定

//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 "AboutGameSceneLoader.h"
bool AboutGameScene::init()
{
if(!CCLayer::init())

}
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：
