cocos2d-x技能冷却

今天看了一个博客 技能冷却，内部原理 没有看懂，但在他的基础上 加了一个代理方法，使外部类能够捕获到冷却结束。博客地址http://http://blog.csdn.net/z104207/article/details/8059098 无侵权意思，

效果：

  
首先 建了一个SkillButton的类
.h文件
ifndef _SKILLBUTTON_H_

#define _SKILLBUTTON_H_

#include "cocos2d.h"

class CMTouchSpriteProtocol;

class SkillButton : public cocos2d::CCNode

{

public:

    SkillButton();

    virtual ~SkillButton();

    

   

    static SkillButton* createSkillButton(float cdTime,

                                          const char* stencil_file_name,

                                          const char* button_normal_name,

                                          const char* button_click_name);

    

   

    void    setCDTime(float time) { mCDTime = time; }

    float   getCDTime() const { return mCDTime; }

    

   

    void    skillClickCallBack(cocos2d::CCObject* obj);

    

   

    void    skillCoolDownCallBack(cocos2d::CCNode* node);

     CC_PROPERTY(CMTouchSpriteProtocol*, _touchSpriteProtocol, TouchSpriteProtocol);

    

private:

    

   

    bool    init(float cdTime, const char* stencil_file_name,const char* button_normal_name, const char* button_click_name);

    

private:

    cocos2d::CCMenuItemImage*   mItemSkill;     // 技能按钮

    cocos2d::CCMenu*            mMenuSkill;     // 技能按钮所在menu

    cocos2d::CCSprite*          mStencil;       // 蒙板精灵,黑色半透明(这个是为了显示一个冷却计时效果)

    cocos2d::CCProgressTimer*   mProgressTimer; // 时间进度条精灵(360度旋转)

    float                       mCDTime;          // CD时间

};

class CMTouchSpriteProtocol {

public:

    // optional

    virtual void CMTouchSpriteSelectSprite(SkillButton*sprite) {

    };

    

};

#endif

.m文件

 

#include "SkillButton.h"

USING_NS_CC;

 

SkillButton::SkillButton():

mItemSkill(NULL),

mMenuSkill(NULL),

mStencil(NULL),

mProgressTimer(NULL),

mCDTime(1.f)

{

    

}

 

SkillButton::~SkillButton()

{

    

}

 

SkillButton* SkillButton::createSkillButton(float cdTime, const char* stencil_file_name, constchar* button_normal_name, const char* button_click_name)

{

    SkillButton* skillButton = new SkillButton();

    if (skillButton && skillButton->init(cdTime, stencil_file_name, button_normal_name, button_click_name))

    {

        skillButton->autorelease();

        return skillButton;

    }

    else

    {

        delete skillButton;

        skillButton = NULL;

    }

    

    return NULL;

}

 

bool SkillButton::init(float cdTime, const char* stencil_file_name, const char* button_normal_name, const char* button_click_name)

{

    CCAssert(stencil_file_name, "SkillButton::init stencil_file_name != NULL");

    CCAssert(button_normal_name, "SkillButton::init button_normal_name != NULL");

    CCAssert(button_click_name, "SkillButton::init button_click_name != NULL");

    

    // Notice:添加child时要注意上下层

    // 最下方是CCMenuItemImage 其次是模版图片 最上方是CCProgressTimer

    

    // 添加技能按钮

    mItemSkill = CCMenuItemImage::create(button_normal_name, button_click_name, this,menu_selector(SkillButton::skillClickCallBack));

    mItemSkill->setPosition(CCPointZero);

    

    mMenuSkill = CCMenu::create(mItemSkill, NULL);

    mMenuSkill->setPosition(CCPointZero);

    addChild(mMenuSkill, -100);

    

    // 添加阴影模版

    mStencil = CCSprite::create(stencil_file_name);

    mStencil->setPosition(CCPointZero);

    mStencil->setVisible(false);

    addChild(mStencil);

    

    // 添加旋转进度条精灵

    CCSprite* progressSprite = CCSprite::create(button_normal_name);

    mProgressTimer = CCProgressTimer::create(progressSprite);

    mProgressTimer->setVisible(false);

    addChild(mProgressTimer, 100);

    

    mCDTime = cdTime;

    return true;

}

 

 

void SkillButton::skillClickCallBack(cocos2d::CCObject* obj)

{

    // 冷却计时，即时状态技能按钮不可点击

    mItemSkill->setEnabled(false);

    

    // 模版可见

    mStencil->setVisible(true);

    

    // 设置精灵进度条为顺时针

    mProgressTimer->setVisible(true);

    mProgressTimer->setType(kCCProgressTimerTypeRadial);

    

    //准备一个5秒旋转360度的动画(逐渐覆盖半透模板形成冷却效果;这里进行计时冷却动画的实现和时间控制)

    CCActionInterval* action_progress_to = CCProgressTo::create(20, 100);

    CCCallFunc* action_callback = CCCallFuncN::create(this,callfuncN_selector(SkillButton::skillCoolDownCallBack));

    mProgressTimer->runAction(CCSequence::create(action_progress_to, action_callback, NULL));

}

 

 

void SkillButton::skillCoolDownCallBack(CCNode* node)

{

    // 设置蒙板不可见

    mStencil->setVisible(false);

    

    // 进度条技能不可见

    mProgressTimer->setVisible(false);

    

    // 按钮置为可用

    mItemSkill->setEnabled(true);

    _touchSpriteProtocol->CMTouchSpriteSelectSprite(this);

}

// 设置协议

void SkillButton::setTouchSpriteProtocol(CMTouchSpriteProtocol *protocol) {

    _touchSpriteProtocol = protocol;

}

CMTouchSpriteProtocol*SkillButton::getTouchSpriteProtocol() {

    return _touchSpriteProtocol;

}

 
 
在 HelloWorldScene调用
#include "cocos2d.h"

#include "SkillButton.h"

class HelloWorld : public cocos2d::CCLayer,publicCMTouchSpriteProtocol

{

public:

    virtual bool init();  

    static cocos2d::CCScene* scene();

    SkillButton*mSkillButton;

    void CMTouchSpriteSelectSprite(SkillButton *sprite);//重写代理方法

    CREATE_FUNC(HelloWorld);

 

};

 

#endif

 

 

mSkillButton = SkillButton::createSkillButton(2.f, "stencil.png", "click.png","normal.png");

    mSkillButton->setPosition(ccp(400/2, 400/2));

    addChild(mSkillButton);

    mSkillButton->setTouchSpriteProtocol(this);

重写代理方法void HelloWorld::CMTouchSpriteSelectSprite(SkillButton*button){

//做冷却结束的事件

}
