CCParticleSystem and its children are not released correctly in tests

Bug #949 [Closed]
walzer@cocos2d-x.org 2012-01-16 02:18 . Updated over 4 years ago

in ParticleTest.cpp, for example

        CCParticleFlower *particle = new CCParticleFlower();  // ref = 1
        particle->init(); // ref = 2 because CCParticleSystem.cpp line 373, this->scheduleUpdateWithPriority(1);
        particle->setTexture( CCTextureCache::sharedTextureCache()->addImage(s_stars1) );  // ref = 2

        particle->release();  // ref = 1
        // in this normal new->init->release sequence, *particle isn't released correctly  

An extra invoke is required:

        CCParticleFlower *particle = new CCParticleFlower();  // ref = 1
        particle->init(); // ref = 2 because CCParticleSystem.cpp line 373, this->scheduleUpdateWithPriority(1);
        particle->setTexture( CCTextureCache::sharedTextureCache()->addImage(s_stars1) );  // ref = 2

        particle->unscheduleUpdate();  // VERY IMPORTANT! ref = 1;
        particle->release();  // ref = 0, released correctly.

CCSchedule may cause “unreleased memory block” in cocos2dx framework. We need to check them.

I didn’t find any memory leak in ParticleTest.

I didn’t find your usage in ParticleTest. After you construct a particle, when you want to use the particle, you surely add it into a CCNode or CCNode’s subclass(e.g. CCLayer), at the time you don’t want to display it, you should invoke removeFromParentAndCleanup function which will call the unscheduleUpdate. Or when the particle’s parent node is destroyed, it will cleanup it’s children which contain your particle. So I don’t think this is a bug.
