摆动的绳子用//逆时针 CCRotateBy *rotaby1=CCRotateBy::actionWithDuration(2,-180);
//顺时针
CCRotateBy *rotaby2=CCRotateBy::actionWithDuration(2,180);
CCSequence seq1=CCSequence::actionOneTwo(rotaby1,rotaby2);
//CCCallFunc::actionWithTarget(this, callfunc_selector(CrashTest::removeThis)
seq1->setTag(110);
CCSpritesprite=(CCSprite *)this->getChildByTag(1010);
sprite->runAction(CCRepeatForever::actionWithAction(seq1));实现,点击屏幕就暂停这个action,然后执行一个拉伸绳子的action,拉伸这儿不会弄了,求指导,是不是思路也有点问题了?CCScaleBy的拉伸会是绳子变细,而且是以绳子中心为左边向两边拉伸,这个要如何解决呢,求高手知道一下
