ios - When to release a CCSpriteBatchNode once the animation is finsihed[Solved] -

-

i playing animation , want remove batch node parent (cclayer) animation finishes playing. running ccsequence have function named animationfinished called when finishes playing. can't remove batch node parent in function released , don't have other retain. game crashes, still being used engine.

so @ event can release batch node. if don't , added again , again cclayer.please see code below

void gamelayer::playanimation(const animationfileandtypeinfo &powerfileinfo,float placeatscreenwidthratio,float placeatscreenheightratio){    std::string firstframe,framename,plist,plistpng;        plist=powerfileinfo.animfileinfo.plist;     plistpng=powerfileinfo.animfileinfo.plistpng;     firstframe=powerfileinfo.animfileinfo.firstframe;     framename=powerfileinfo.animfileinfo.framename;      // generic animation play code     ccspriteframecache *animcache = ccspriteframecache::sharedspriteframecache();     animcache->addspriteframeswithfile(plist.c_str());      _animplaybatchnode = ccspritebatchnode::create(plistpng.c_str(), 100);     this->addchild(_animplaybatchnode,kforeground+1);      short numberofframes=getplistframescount(plist.c_str(),"frames");// plist full name postfix .plist      ccarray *spriteframes = ccarray::createwithcapacity(numberofframes);     spriteframes->retain();      _animplayfirstsprite = ccsprite::createwithspriteframename(firstframe.c_str());// postfix .png     _animplaybatchnode->addchild(_animplayfirstsprite,kforeground+1);     _animplayfirstsprite->setposition(ccp(_screensize.width*placeatscreenwidthratio, _screensize.height*placeatscreenheightratio));      for(int = 1; <= numberofframes; i++)     {         char szname[50] = {0};         sprintf(szname, "%s%i.png",framename.c_str(),i);         ccspriteframe* frame = animcache->spriteframebyname(szname);         spriteframes->addobject(frame);     }      ccanimation *animation = ccanimation::createwithspriteframes(spriteframes,0.05f);     animation->retain();     animation->setdelayperunit(0.08f);// 0.05f      ccsequence *seq=ccsequence::createwithtwoactions(ccanimate::create(animation), cccallfunco::create(animation,callfunco_selector(gamelayer::animationfinished),(ccobject*)_animplaybatchnode));      _animplayfirstsprite->runaction(seq);      spriteframes->release();     animation->release();  } void gamelayer::animationfinished(ccobject *sender){  ccspritebatchnode *animbatchnode = (ccspritebatchnode*) sender; animbatchnode->removeallchildrenwithcleanup(true); _isanimationalreadyplaying=false;  //   animbatchnode->removefromparent() , crashes if  }
