    Cocos2d—X游戏开发之CCToggle(菜单标签切换)

    首先继承子CCMenu,是菜单标签中的一种。‘

    class CC_DLL CCMenuItemToggle : public CCMenuItem
    {
        /** returns the selected item */
        CC_PROPERTY(unsigned int, m_uSelectedIndex, SelectedIndex);
        /** CCMutableArray that contains the subitems. You can add/remove items in runtime, and you can replace the array with a new one.
         @since v0.7.2
         */
        CC_PROPERTY(CCArray*, m_pSubItems, SubItems);
    public:
        CCMenuItemToggle()
        : m_uSelectedIndex(0)
        , m_pSubItems(NULL)            
        {}
        virtual ~CCMenuItemToggle();
    
        /** creates a menu item from a list of items with a target/selector */
        static CCMenuItemToggle* createWithTarget(CCObject* target, SEL_MenuHandler selector, CCMenuItem* item, ...);  
    
        /** creates a menu item with no target/selector and no items */
        static CCMenuItemToggle* create();
    
        /** initializes a menu item from a list of items with a target selector */
        bool initWithTarget(CCObject* target, SEL_MenuHandler selector, CCMenuItem* item, va_list args);
    
        /** creates a menu item with a item */
        static CCMenuItemToggle* create(CCMenuItem *item);
    
        /** initializes a menu item with a item */
        bool initWithItem(CCMenuItem *item);
        /** add more menu item */
        void addSubItem(CCMenuItem *item);
        
        /** return the selected item */
        CCMenuItem* selectedItem();
        // super methods
        virtual void activate();
        virtual void selected();
        virtual void unselected();
        virtual void setEnabled(bool var);
        
        virtual void setOpacityModifyRGB(bool bValue) {CC_UNUSED_PARAM(bValue);}
        virtual bool isOpacityModifyRGB(void) { return false;}
    };


    主要使用的下面的几个方法:

    初始化菜单标签

    static CCMenuItemToggle* createWithTarget(CCObject* target, SEL_MenuHandler selector, CCMenuItem* item, ...);


    返回当前有效的标签

    CCMenuItem* selectedItem();


    设置标签是否响应点击

    virtual void setEnabled(bool var);

    返回当前标签的数组下标

    这个方法的声明是通过宏定义来实现的

    CC_PROPERTY(unsigned int, m_uSelectedIndex, SelectedIndex);
    #define CC_PROPERTY(varType, varName, funName)
    protected: varType varName;
    public: virtual varType get##funName(void);
    public: virtual void set##funName(varType var);
    unsigned int CCMenuItemToggle::getSelectedIndex()
    {
        return m_uSelectedIndex;
    }
    



    有了这些方法,就可以实现菜单标签切换的效果了。




    CCControlSwitch这个控件用于声音关闭,开启的选项。使用中要注意一点是,点的精灵一定要小。

    class CCControlSwitchSprite;
    
    /**
     * @addtogroup GUI
     * @{
     * @addtogroup control_extension
     * @{
     */
    
    /** @class CCControlSwitch Switch control for Cocos2D. */
    class CCControlSwitch : public CCControl
    {
    public:
        CCControlSwitch();
        virtual ~CCControlSwitch();
        /** Initializes a switch with a mask sprite, on/off sprites for on/off states and a thumb sprite. */
        bool initWithMaskSprite(CCSprite *maskSprite, CCSprite * onSprite, CCSprite * offSprite, CCSprite * thumbSprite);
    
        /** Creates a switch with a mask sprite, on/off sprites for on/off states and a thumb sprite. */
        static CCControlSwitch* create(CCSprite *maskSprite, CCSprite * onSprite, CCSprite * offSprite, CCSprite * thumbSprite);
    
    
        /** Initializes a switch with a mask sprite, on/off sprites for on/off states, a thumb sprite and an on/off labels. */
        bool initWithMaskSprite(CCSprite *maskSprite, CCSprite * onSprite, CCSprite * offSprite, CCSprite * thumbSprite, CCLabelTTF* onLabel, CCLabelTTF* offLabel);
    
        /** Creates a switch with a mask sprite, on/off sprites for on/off states, a thumb sprite and an on/off labels. */
        static CCControlSwitch* create(CCSprite *maskSprite, CCSprite * onSprite, CCSprite * offSprite, CCSprite * thumbSprite, CCLabelTTF* onLabel, CCLabelTTF* offLabel);
    
    
        /**
         * Set the state of the switch to On or Off, optionally animating the transition.
         *
         * @param isOn YES if the switch should be turned to the On position; NO if it 
         * should be turned to the Off position. If the switch is already in the 
         * designated position, nothing happens.
         * @param animated YES to animate the "flipping" of the switch; otherwise NO.
         */
        void setOn(bool isOn, bool animated);
        void setOn(bool isOn);
        bool isOn(void) { return m_bOn; }
        bool hasMoved() { return m_bMoved; }
        virtual void setEnabled(bool enabled);
    
        CCPoint locationFromTouch(CCTouch* touch);
        //events
        virtual bool ccTouchBegan(CCTouch *pTouch, CCEvent *pEvent);
        virtual void ccTouchMoved(CCTouch *pTouch, CCEvent *pEvent);
        virtual void ccTouchEnded(CCTouch *pTouch, CCEvent *pEvent);
        virtual void ccTouchCancelled(CCTouch *pTouch, CCEvent *pEvent);
    
    protected:
        /** Sprite which represents the view. */
        CCControlSwitchSprite* m_pSwitchSprite;
        float m_fInitialTouchXPosition;
        
        bool m_bMoved;
        /** A Boolean value that determines the off/on state of the switch. */
        bool m_bOn;
    };
    


    CCControlSwitch的使用方法比较简单,看了上面的方法简介,应该使用没有问题,源码可以自己去研究

    CCControlSwitch *switchMenu = CCControlSwitch::create(CCSprite::create("ZF_Shoot_RankingList_money1.png"), CCSprite::create("ZF_Shoot_RankingList_money1.png"), CCSprite::create("ZF_Shoot_RankingList_shoot1.png"), temp);
        switchMenu->setPosition(ccp(winSize.width/2, winSize.height*0.5));
        switchMenu->addTargetWithActionForControlEvents(this, cccontrol_selector(RankScene::menuCall), CCControlEventValueChanged);
        this->addChild(switchMenu, 0);


    然后,判断它的开关状态来调用相应的方法:

        CCControlSwitch *Sender = (CCControlSwitch *)pSender;
        if (Sender->isOn())
        {
            CCLOG("************************************");
            CCLOG("CCControlSwitch is on");
        }
        else
        {
            CCLOG("************************************");
            CCLOG("CCControlSwitch is off");
        }
