cocos2dx 3.2版本。。。

 class TScale:public cocos2d ::ScaleTo{

public:
    TScale(void);
    ~TScale(void);
    
    static TScale* actionWithDuration(float duration,float scale);
    virtual void startWithTarget(Node *target);
    virtual void update(float time);
    
    void removeTaget(Node *node);
private:
    float alreadyTime;
    
};


```



 TScale::TScale(void)
{
}



TScale::~TScale(void)
{
}

TScale* TScale::actionWithDuration(float duration, float scale){
    TScale *ts=new TScale();
    ts->create(duration, scale);
    
    
    
    return ts;
};



void TScale::startWithTarget(cocos2d::Node *target){
    this->setTarget(target);
    this->alreadyTime=0;
}

void TScale::update(float time){

    if(this->getTarget()!=NULL){
        this->getTarget()->setScaleX(_startScaleX+_deltaX*time);
        this->getTarget()->setScaleY(_startScaleY+_deltaY*time);
        this->alreadyTime+=time*this->getDuration();
        
        if(this->alreadyTime>0.5 && time>0.5){
            this->alreadyTime=0;
            
            Sprite *_clearSprite=Sprite::create("Star1.png");
            _clearSprite->setAnchorPoint(this->getTarget()->getAnchorPoint());
            _clearSprite->setPosition(this->getTarget()->getPosition());
            _clearSprite->setScale(this->getTarget()->getScale());
            
            _clearSprite->setOpacity(this->getTarget()->getOpacity());
            
            this->getTarget()->getParent()->addChild(_clearSprite);
            
            
            Sequence *sequence=Sequence::create(FadeTo::create(0.2, 0),
                                                CC_CALLBACK_1(TScale::removeTaget, this->getTarget()->getParent()),NULL);
            _clearSprite->runAction(sequence);
        }
    }
}


void TScale::removeTaget(Node *node){
    node->removeFromParentAndCleanup(true);
}

我擦。。代码高亮居然有问题。。。

我重新贴下，h和cpp的代码

class TScale:public cocos2d ::ScaleTo{
public:
TScale(void);
~TScale(void);

static TScale* actionWithDuration(float duration,float scale);
virtual void startWithTarget(Node *target);
virtual void update(float time);

void removeTaget(Node *node);

private:
float alreadyTime;
};

cpp：

TScale::TScale(void)
{
}

TScale::~TScale(void)
{
}

TScale* TScale::actionWithDuration(float duration, float scale){
TScale *ts=new TScale();
ts->create(duration, scale);

return ts;

};

void TScale::startWithTarget(cocos2d::Node *target){
this->setTarget(target);
this->alreadyTime=0;
}

void TScale::update(float time){

if(this->getTarget()!=NULL){

this->getTarget()->setScaleX(_startScaleX+_deltaXtime);
this->getTarget()->setScaleY(_startScaleY+_deltaYtime);
this->alreadyTime+=time*this->getDuration();

    if(this->alreadyTime>0.5 && time>0.5){
        this->alreadyTime=0;

        Sprite *_clearSprite=Sprite::create("Star1.png");
        _clearSprite->setAnchorPoint(this->getTarget()->getAnchorPoint());
        _clearSprite->setPosition(this->getTarget()->getPosition());
        _clearSprite->setScale(this->getTarget()->getScale());

        _clearSprite->setOpacity(this->getTarget()->getOpacity());

        this->getTarget()->getParent()->addChild(_clearSprite);


        Sequence *sequence=Sequence::create(FadeTo::create(0.2, 0),
                                            CC_CALLBACK_1(TScale::removeTaget, this->getTarget()->getParent()),NULL);
        _clearSprite->runAction(sequence);
    }
}

}

void TScale::removeTaget(Node *node){
node->removeFromParentAndCleanup(true);
}

update的time应该是每一帧的进度，怎么会第一次就是1？是不是哪里需要添加什么代码，我遗漏了。。

#4

void TScale::update(float time){
这个参数第一次运行是1，不是其他？

#5

对啊。第1次就是1了。。
