示例1: reorderChild

// Reorder will be done in this function, no "lazy" reorder to particles
void CCParticleBatchNode::reorderChild(CCNode * child, int zOrder)
{

    CCAssert( child != NULL, "Child must be non-NULL");
    CCAssert( dynamic_cast<CCParticleSystem*>(child) != NULL, "CCParticleBatchNode only supports CCQuadParticleSystems as children");
    CCAssert( m_pChildren->containsObject(child), "Child doesn't belong to batch" );

    CCParticleSystem* pChild = (CCParticleSystem*)(child);

    if( zOrder == child->getZOrder() )
    {
        return;
    }

    // no reordering if only 1 child
    if( m_pChildren->count() > 1)
    {
        unsigned int newIndex = 0, oldIndex = 0;

        getCurrentIndex(&oldIndex, &newIndex, pChild, zOrder);

        if( oldIndex != newIndex )
        {

            // reorder m_pChildren->array
            pChild->retain();
            m_pChildren->removeObjectAtIndex(oldIndex);
            m_pChildren->insertObject(pChild, newIndex);
            pChild->release();

            // save old altasIndex
            unsigned int oldAtlasIndex = pChild->getAtlasIndex();

            // update atlas index
            updateAllAtlasIndexes();

            // Find new AtlasIndex
            unsigned int newAtlasIndex = 0;
            for( unsigned int i=0; i < m_pChildren->count(); i++)
            {
                CCParticleSystem* pNode = (CCParticleSystem*)m_pChildren->objectAtIndex(i);
                if( pNode == pChild )
                {
                    newAtlasIndex = pChild->getAtlasIndex();
                    break;
                }
            }

            // reorder textureAtlas quads
            m_pTextureAtlas->moveQuadsFromIndex(oldAtlasIndex, pChild->getTotalParticles(), newAtlasIndex);

示例2: removeChild

// override removeChild:
void  CCParticleBatchNode::removeChild(CCNode* child, bool cleanup)
{
    // explicit nil handling
    if (child == NULL)
    {
        return;
    }
    
    CCAssert( dynamic_cast<CCParticleSystem*>(child) != NULL, "CCParticleBatchNode only supports CCQuadParticleSystems as children");
    CCAssert(m_pChildren->containsObject(child), "CCParticleBatchNode doesn't contain the sprite. Can't remove it");

    CCParticleSystem* pChild = (CCParticleSystem*)child;
    CCNode::removeChild(pChild, cleanup);

    // remove child helper
    m_pTextureAtlas->removeQuadsAtIndex(pChild->getAtlasIndex(), pChild->getTotalParticles());

    // after memmove of data, empty the quads at the end of array
    m_pTextureAtlas->fillWithEmptyQuadsFromIndex(m_pTextureAtlas->getTotalQuads(), pChild->getTotalParticles());

    // particle could be reused for self rendering
    pChild->setBatchNode(NULL);

    updateAllAtlasIndexes();

示例3: addChild

void CCParticleBatchNode::addChild(CCNode * child, int zOrder, int tag)
{
    CCAssert( child != NULL, "Argument must be non-NULL");
    CCAssert( dynamic_cast<CCParticleSystem*>(child) != NULL, "CCParticleBatchNode only supports CCQuadParticleSystems as children");
    CCParticleSystem* pChild = (CCParticleSystem*)child;
    CCAssert( pChild->getTexture()->getName() == m_pTextureAtlas->getTexture()->getName(), "CCParticleSystem is not using the same texture id");
    // If this is the 1st children, then copy blending function
    if( m_pChildren->count() == 0 ) 
    {
        setBlendFunc(pChild->getBlendFunc());
    }

    CCAssert( m_tBlendFunc.src  == pChild->getBlendFunc().src && m_tBlendFunc.dst  == pChild->getBlendFunc().dst, "Can't add a PaticleSystem that uses a different blending function");

    //no lazy sorting, so don't call super addChild, call helper instead
    unsigned int pos = addChildHelper(pChild,zOrder,tag);

    //get new atlasIndex
    unsigned int atlasIndex = 0;

    if (pos != 0) 
    {
        CCParticleSystem* p = (CCParticleSystem*)m_pChildren->objectAtIndex(pos-1);
        atlasIndex = p->getAtlasIndex() + p->getTotalParticles();

    }
    else
    {
        atlasIndex = 0;
    }

    insertChild(pChild, atlasIndex);

    // update quad info
    pChild->setBatchNode(this);
