In the example of osgparticleeffects,how to know that the particle effects
disappear?
I find the function areAllParticlesDead does't work.Is there any other way to
judge it??
If I do like this,when the particle effects disappears,but memory don't
release! Why?
bool handle(const osgGA::GUIEventAdapter& ea,osgGA::GUIActionAdapter& aa)
{
osgViewer::Viewer* viewer = dynamic_cast<osgViewer::Viewer*>(&aa);
osg::Group* group = dynamic_cast<osg::Group*>(viewer->getSceneData()) ;
group->setDataVariance(osg::Object::DYNAMIC) ;
osgParticle::ExplosionEffect* ee
=dynamic_cast<osgParticle::ExplosionEffect*>(group->getChild(1)) ;
switch(ea.getEventType())
{
case(osgGA::GUIEventAdapter::PUSH):
{
if(ee->areAllParticlesDead())
{
group->removeChild(1) ;
group->removeChild(2) ;
group->removeChild(3) ;
group->removeChild(4) ;
}
}
return false;
default:
return false;
}
}
Thank you!
