void ActionMove::onEnter()
{
    ActionsDemo::onEnter();

    centerSprites(3);

    CCSize s = CCDirector::sharedDirector()->getWinSize();

    CCActionInterval*  actionTo = CCMoveTo::create(2, ccp(s.width-40, s.height-40));
    CCActionInterval*  actionBy = CCMoveBy::create(4, ccp(80,80));
    CCActionInterval*  actionByBack = actionBy->reverse();

    m_tamara->runAction( actionTo);
    m_grossini->runAction( CCSequence::create(actionBy, actionByBack, NULL));
    m_kathia->runAction(CCMoveTo::create(1, ccp(40,40)));
}

ActionsDemo::onEnter();

初始化界面；

 

centerSprites(3);

四种情况下，设定三个小人的位置，其余在ActionsDemo::onEnter();中已设定位置

else if( numberOfSprites == 3 ) 
    {
        m_grossini->setPosition( ccp(s.width/2, s.height/2));
        m_tamara->setPosition( ccp(s.width/4, s.height/2));
        m_kathia->setPosition( ccp(3 * s.width/4, s.height/2));
    }

CCMoveTo* CCMoveTo::create(float duration, const CCPoint& position)

在duration时间内，移动到position位置；

 

CCMoveBy* CCMoveBy::create(float duration, const CCPoint& deltaPosition)

假设deltaPosition=（a， b）

在duration时间内，X方向移动a距离， y方向移动b距离；

 

actionBy->reverse();

相同时间，原路返回；

 

CCSequence::create

顺序动作
