CCCatmullRomBy和CCPointArray

CCCatmullRomBy:把某一对象以Catmull-Rom curve曲线移动一段距离

    CCPointArray *array = CCPointArray::create();

    array->addControlPoint(ccp(, ));
    array->addControlPoint(ccp(, ));
    array->addControlPoint(ccp(s.width - , ));

    array->addControlPoint(ccp(s.width / , s.height / ));

    CCCatmullRomBy *action = CCCatmullRomBy::create(, array);
    CCFiniteTimeAction *reverse = action->reverse();

    CCFiniteTimeAction *seq = CCSequence::create(action, reverse, NULL);

    m_tamara->runAction(seq);
