示例1: reorderChild
// Reorder will be done in this function, no "lazy" reorder to particles
void ParticleBatchNode::reorderChild(Node * aChild, int zOrder)
{
CCASSERT( aChild != nullptr, "Child must be non-nullptr");
CCASSERT( dynamic_cast<ParticleSystem*>(aChild) != nullptr, "CCParticleBatchNode only supports QuadParticleSystems as children");
CCASSERT( _children.contains(aChild), "Child doesn't belong to batch" );
ParticleSystem* child = static_cast<ParticleSystem*>(aChild);
if( zOrder == child->getLocalZOrder() )
{
return;
}
// no reordering if only 1 child
if (!_children.empty())
{
int newIndex = 0, oldIndex = 0;
getCurrentIndex(&oldIndex, &newIndex, child, zOrder);
if( oldIndex != newIndex )
