粒子效果出现的问题求助

m_particle = CCParticleGalaxy::create();

m_particle->setTexture( CCTextureCache::sharedTextureCache()->addImage(“fire.png”) );

m_particle->setPosition(ccp(m_plane->getContentSize().width * 0.5,0));

m_particle->setGravity(ccp(-90,0));
m_particle->setVisible(false);

m_particle->setTag(M_PARTICLE);

m_plane->addChild(m_particle,10);

之后再我程序运行时,我设置m_particle->setvisible(true),
程序就崩溃了 报错,跟代码之后 m_uparticeldx为0 , m_uparticleCount为200. 1063
