Cocos2d-X在SwitchControl使用

SwitchControl控制类中的一个开关的发挥了作用似在现实生活中开关

因为控制相对简单，我没有做过多的解释。直接在代码

首先在project文件夹下的Resource文件夹中加入三张图片

在SwitchControl.h加入以下代码

#ifndef   _SwitchControl_H_
#define  _SwitchControl_H_

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

class SwitchControl : public CCLayer 
{
public:
    static CCScene* scene();
	CREATE_FUNC(SwitchControl);
	bool init();
	void switchValueChanged(CCObject*, CCControlEvent);
};

#endif

在SwitchControl.cpp中加入以下代码

#include "SwitchControl.h"

CCScene* SwitchControl::scene()
{
	CCScene* s = CCScene::create();
	SwitchControl* layer = SwitchControl::create();
	s->addChild(layer);
	return s;
}

bool SwitchControl::init()
{ 
    CCLayer::init();

    //得到窗体的大小
    CCSize winSize = CCDirector::sharedDirector()->getWinSize();   

    //设置ControlSwitch控件打开的文字No"
	CCLabelTTF* on = CCLabelTTF::create("ON", "Arial", 16);
	
    //设置ControlSwitch控件关闭时的文字"OFF"
    CCLabelTTF* off = CCLabelTTF::create("OFF", "Arial", 16);
	
    //设置ControlSwitch控件打开的文字的颜色
    on->setColor(ccc3(0, 0, 0));

    //设置ControlSwitch控件关闭时的颜色
	off->setColor(ccc3(0, 0, 0));

    //创建ControlSwitch控件
    CCControlSwitch* control = CCControlSwitch::create(
	    CCSprite::create("switch-mask.png"),
	    CCSprite::create("switch-on.png"),
	    CCSprite::create("switch-off.png"),
	    CCSprite::create("switch-thumb.png"),
	    on,
	    off);

        //加入ControlSwitch控件
        addChild(control);
      
        //设置ControlSwitch控件的位置
        control->setPosition(ccp(winSize.width / 2, winSize.height / 2));

		// 注冊valuechange消息，当valuechange时。调用switchValueChanged函数
		control->addTargetWithActionForControlEvents(this, 
			cccontrol_selector(SwitchControl::switchValueChanged), 
			CCControlEventValueChanged);
		
		return true;
}

void SwitchControl::switchValueChanged(CCObject* sender, CCControlEvent ev)
{
	if (ev == CCControlEventValueChanged)
	{
		CCControlSwitch* control = (CCControlSwitch*)sender;
		if (control->isOn())
		{
			CCLog("Switch if ON");
		}
		else
		{
			CCLog("Swith is Off");
		}
	}
	else
	{
		CCLog("other events");
	}
}

运行结果：
