cocos2dx v3 with cocosbuilder

概要

• cocos2dxの3.3でcocosBuilderの対応関係のメモ
• cocos2dxの2.xでしかcocosBuilder使ったことなかったのでハマった

環境

• Mac OSX 10.10
• cocos2dx v3.3
• cocosbuilder v3.0α （[Download](https://code.google.com/p/cocosbuilder/downloads/detail?name=CocosBuilder-3.0-alpha5.zip&can=2&q=, cocosbuilder)）

基本確認

• とりあえずCCがとれたらしい...
• CCNode → Node
• CCLayer → Layer
• 以下略。

cocosBuilder側の操作

• rootNode(Layer？)にcustomClassを設定。今回はOpeningLayerにした
• buttonとか設置
• buttonのcallbackセレクタとか設定。document Rootにアタッチ。
• Sprite（画像）とか設置
• code connectionでdoc root varとnameを設定。

Loaderクラスの作成

• OpeningLayerLoader.h
• CocosBuilder.hのincludeがよく分かってない... とりあえず階層全部のせたらうまくいった...

#include "cocos2d.h"
#include "cocos-ext.h"
#include "OpeningLayer.h"
#include "editor-support/cocosbuilder/CocosBuilder.h"

class OpeningLayerLoader: public cocosbuilder::LayerLoader {
public:
    CCB_STATIC_NEW_AUTORELEASE_OBJECT_METHOD(OpeningLayerLoader, loader);
    
    CCB_VIRTUAL_NEW_AUTORELEASE_CREATECCNODE_METHOD(OpeningLayer);
};

OpeningLayerクラスの作成

• OpeningLayer.h

#include "cocos2d.h"
#include "cocos-ext.h"
#include "cocosbuilder/CocosBuilder.h"
USING_NS_CC;
USING_NS_CC_EXT;

class OpeningLayer:
public cocos2d::Layer,
public cocosbuilder::CCBMemberVariableAssigner,
public cocosbuilder::CCBSelectorResolver
{
public:
    static Scene* createScene();
    OpeningLayer();
    ~OpeningLayer();
    CREATE_FUNC(OpeningLayer);
    
    bool init(){return true;};
    
    bool onAssignCCBMemberVariable(cocos2d::Ref* pTarget, const char* pMemberVariableName, cocos2d::Node* pNode);
    cocos2d::SEL_MenuHandler onResolveCCBCCMenuItemSelector(cocos2d::Ref * pTarget, const char* pSelectorName)
    { return nullptr;};
    Control::Handler onResolveCCBCCControlSelector(cocos2d::Ref * pTarget, const char* pSelectorName);
    cocos2d::SEL_CallFuncN onResolveCCBCCCallFuncSelector(cocos2d::Ref * pTarget, const char* pSelectorName)
    { return NULL; };
    
    void onPushButton(Ref* pSender, cocos2d::extension::Control::EventType event);
    void onPushReplaceScene(Ref* pSender, cocos2d::extension::Control::EventType event);
private:
    Sprite *_image;
};

• OpeningLayer.cpp
• 長くなるのでcocosbuilder関係のとこだけ。

bool OpeningLayer::onAssignCCBMemberVariable(cocos2d::Ref *pTarget, const char *pMemberVariableName, Node *pNode)
{
    CCB_MEMBERVARIABLEASSIGNER_GLUE_WEAK(this, "image", Sprite*, _image);
    return false;
}

cocos2d::extension::Control::Handler OpeningLayer::onResolveCCBCCControlSelector(cocos2d::Ref * pTarget, const char* pSelectorName)
{
    CCB_SELECTORRESOLVER_CCCONTROL_GLUE(this, "pushButton", OpeningLayer::onPushButton);
    CCB_SELECTORRESOLVER_CCCONTROL_GLUE(this, "replaceScene", OpeningLayer::onPushReplaceScene);
    return nullptr;
}

とりあえずこれで動いた。

読み込み

cocosbuilder::NodeLoaderLibrary* pNodeLoaderLibrary = cocosbuilder::NodeLoaderLibrary::getInstance();
pNodeLoaderLibrary->registerNodeLoader("OpeningLayer", OpeningLayerLoader::loader());
cocosbuilder::CCBReader* pReader = new cocosbuilder::CCBReader(cocosbuilder::NodeLoaderLibrary::getInstance());
Node *n = pReader->readNodeGraphFromFile("OpeningLayer.ccbi");

• 必要に応じてcastしてもよい。
