cocos2d-x中继承CCMenu定义自己的MyMenu，这个是解决优先级的问题

为了用menu来进行对touch事件的阻断，防止其传到下一层，又不能影响上面的CCControlButton等优先级为0的sprite的点击响应，于是就定义了一个MyMenu。

下面为相关代码，下一篇(cocos2d-x里面touch事件传递机制 .)我再详细说下cocos2d-x里面的touch事件响应机制

 

这里面代码（1）（2）是MyMenu的例子，（7）（8）里面控制touch传递的例子

（1）MyMenu.h

#pragma once

// MyMenu

#include "cocos2d.h"

using namespace cocos2d;

class MyMenu : public CCMenu
{
public:
	MyMenu(void);
	~MyMenu(void);

	/** creates a CCMenu with it's items */
	static MyMenu* create(CCMenuItem* item, ...);

	// 重写registerWithTouchDispatcher
	virtual void registerWithTouchDispatcher();
};

（2）MyMenu.cpp

#include "MyMenu.h"

MyMenu::MyMenu(void)
{
}

MyMenu::~MyMenu(void)
{
}

MyMenu * MyMenu::create(CCMenuItem* item, ...)
{
	va_list args;
	va_start(args,item);
	MyMenu *pRet = new MyMenu();
	if (pRet && pRet->initWithItems(item, args))
	{
		pRet->autorelease();
		va_end(args);
		return pRet;
	}
	va_end(args);
	CC_SAFE_DELETE(pRet);
	return NULL;
}


// 重写registerWithTouchDispatcher
void MyMenu::registerWithTouchDispatcher()
{
	//这里优先级设为1，只要比CCScrollView、tableView、CCControlButton等（这些优先级都为0）低就可以
	CCDirector::sharedDirector()->getTouchDispatcher()->addTargetedDelegate(this, 1, true);
}

 

（3）BattleBGLayer.h

#pragma once

// 战役界面(包含左侧的选项栏layer(BattleZuoLayer)、承载战役场景的layer(BattleShowLayer)等)layer

#include "cocos2d.h"
#include "cocos-ext.h"

using namespace cocos2d;
using namespace cocos2d::extension;

class BattleBGLayer : public CCLayer
{
public:
	BattleBGLayer(void);
	~BattleBGLayer(void);

public:
	// init
	virtual bool init();

	CREATE_FUNC(BattleBGLayer);
};

（4）BattleBGLayer.cpp

#include "BattleBGLayer.h"
#include "BattleShowLayer.h"
#include "BattleZuoLayer.h"


//****************************************变量begin**********************************
// 定义全局变量
int bl_showNumber = 1;		// 选择的是哪个战役
//****************************************变量end*************************************


BattleBGLayer::BattleBGLayer(void)
{
}

BattleBGLayer::~BattleBGLayer(void)
{
}


// init
bool BattleBGLayer::init()
{
	if (!CCLayer::init())
	{
		return false;
	}


	// 承载战役场景的layer(BattleShowLayer)
	BattleShowLayer* battleShowLayer = BattleShowLayer::create();
	this->addChild(battleShowLayer,0,1000);

	// 左侧的选项栏layer(BattleZuoLayer)
	BattleZuoLayer* battleZuoLayer = BattleZuoLayer::create();
	this->addChild(battleZuoLayer,10,1001);


	return true;
}

（5）BattleShowLayer.h

#pragma once
