Cocos2dx - play frame animation forever, but pause for a few second before the repeat

Question

I am trying to play a frame animation sequence looping forever, but after each play, I'd like to delay for a period of time before the next loop.

Here's the specific code:

    CCActionInterval *pAnimate = CCAnimate::create( m_pAnimationDebugSkill );
    CCDelayTime *pDelayTime = CCDelayTime::create( 3.0f );
    CCRepeatForever *pRepeat = CCRepeatForever::create( CCSequence::createWithTwoActions(pAnimate, pDelayTime) );
    m_pSpriteDebugSkillAnimation->runAction( pRepeat );

I am expecting pAnimate to play, then pDelayTime to hold for 3 seconds, then pAnimate to play again... But what happens is pAnimate is playing and repeating forever... pDelayTime has no effect at all...

Anyone has any idea?

Here's the complete code:

        // Skill button animation
    m_pSpriteDebugSkillAnimation = CCSprite::createWithSpriteFrame(
        CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(s_szNameSpriteFrame[UI_BOARD_RUNES_ANIM_BTN_SKILL_0])
    );
    m_pSpriteDebugSkillAnimation->setAnchorPoint(ccp(0.5f, 0.5f));
    INT iNumFrames = UI_BOARD_RUNES_ANIM_BTN_SKILL_END - UI_BOARD_RUNES_ANIM_BTN_SKILL_START + 1;
    CCArray *pAnimSkill = CCArray::create();
    for ( INT i = 0; i < iNumFrames; i++ ) {
        CCSpriteFrame *pFrame = CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(s_szNameSpriteFrame[UI_BOARD_RUNES_ANIM_BTN_SKILL_0+i]);
        pAnimSkill->addObject(pFrame);
    }
    m_pAnimationDebugSkill = CCAnimation::createWithSpriteFrames( pAnimSkill, DEFAULT_TIME_ANIM );
    m_pAnimationDebugSkill->setLoops( -1 );
    m_pAnimationDebugSkill->retain();
    CCActionInterval *pAnimate = CCAnimate::create( m_pAnimationDebugSkill );
    CCDelayTime *pDelayTime = CCDelayTime::create( 3.0f );
    CCRepeatForever *pRepeat = CCRepeatForever::create( CCSequence::createWithTwoActions(pAnimate, pDelayTime) );
    m_pSpriteDebugSkillAnimation->runAction( pRepeat );

    CCSprite *pSpriteSkill = CCSprite::createWithSpriteFrame(
        CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(s_szNameSpriteFrame[UI_BOARD_RUNES_BTN_SKILL])
    );
    FLOAT fSpriteSkillWidth = pSpriteSkill->boundingBox().size.width;
    FLOAT fSpriteSkillHeight = pSpriteSkill->boundingBox().size.height;
    m_pSpriteDebugSkillAnimation->setPosition(ccp(fSpriteSkillWidth/2.0f, fSpriteSkillHeight/2.0f));
    pSpriteSkill->addChild( m_pSpriteDebugSkillAnimation );
    //pSpriteSkill->setAnchorPoint(ccp(0.5f, 0.5f));
    //pSpriteSkill->setPosition(ccp(fScreenHalfWidth, 1100.0f));
    //this->addChild(pSpriteSkill);
    m_pBtnDebugSkill = CCMenuItemSprite::create( pSpriteSkill, pSpriteSkill, pSpriteSkill, this, menu_selector(CGameScreen::onTouchSkillButton) );
    m_pBtnDebugSkill->setPosition(ccp(fScreenHalfWidth, 1100.0f));
    m_pMenuRoot->addChild( m_pBtnDebugSkill );

You could try running the animation in a function:

void MyGame::runMyAnimation()
{
    CCActionInterval *pAnimate = CCAnimate::create( m_pAnimationDebugSkill );
    m_pSpriteDebugSkillAnimation->runAction( pAnimate );
}

and run this code instead:

CCDelayTime *pDelayTime = CCDelayTime::create( 3.0f /* add the time the animation takes here*/);
CCRepeatForever *pRepeat = CCRepeatForever::create( CCSequence::createWithTwoActions(pDelayTime, CCCallFunc::create(this,callfunc_selector(MyGame::runMyAnimation)));

UPDATE

Probably your code works like this:

Start animation
wait for 3 seconds (while the animation is running)
Start animation again

Try adding the time your animation takes to the delay time.

Place delay first and then after run animation in sequence.It will work — Rama, Nov 20 '13 at 11:26

the problem is that you have set loops for m_pAnimationDebugSkill to -1.

    m_pAnimationDebugSkill->setLoops( -1 );

this is making this animation run for infinite and therefore the delay part is not executing ..

you don't need to set loops to -1 if you are later using ccrepeatforever.

other then that the code looks fine
