Hi,
Iwould like to introspect StateSet in order to know which override value is
activated for a particular stateset.
I parse AttributeList for this
Code:
for( osg::StateSet::AttributeList::const_iterator
it=ss->getAttributeList().begin();it!=ss->getAttributeList().end() ; it++)
{
if((*it).second.first ==stateattribute)
{
if( (*it).second.second & osg::StateAttribute::ON)
return(1);
else return(0);
}
but according to StateSet.cpp l.1662
Code:
attributeList[attribute->getTypeMemberPair()] =
RefAttributePair(attribute,value&(StateAttribute::OVERRIDE|StateAttribute::PROTECTED));
the ON OFF bit is removed from the given user value. So I can't determine if an
osg::Attribute is ON or OFF but only if it's OVERRIDE or PROTECTED
I would like to know if there's a known reason behind this logic & and further
if you know a mean to retrieve the ON/OFF bit.
Thank you!
Cheers,
Julien
