Hi Cedric,
I'm using OSG 2.9.6 (61) but with the latest osgAnimation from svn (2.9.8).
I added these lines to osgviewer (just before setting scene data):
AnimationManagerFinder finder;
loadedModel->accept(finder);
if(finder._am.valid())
{
osg::notify(osg::WARN) << "osgAnimation::AnimationManagerBase found in
the subgraph..." << std::endl;
loadedModel->setUpdateCallback(finder._am.get());
}
else
{
osg::notify(osg::WARN) << "no osgAnimation::AnimationManagerBase found
in the subgraph, no animations available" << std::endl;
}
and I defined the visitor like this:
struct AnimationManagerFinder : public osg::NodeVisitor
{
osg::ref_ptr<osgAnimation::BasicAnimationManager> _am;
AnimationManagerFinder() :
osg::NodeVisitor(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN) {}
void apply(osg::Node& node)
{
if (_am.valid())
return;
if (node.getUpdateCallback())
{
osgAnimation::AnimationManagerBase* b =
dynamic_cast<osgAnimation::AnimationManagerBase*>(node.getUpdateCallback());
if (b)
{
osg::notify(osg::FATAL)<<"found
AnimationManagerBase..."<<std::endl;
_am = new osgAnimation::BasicAnimationManager(*b);
int i=0;
osgAnimation::AnimationList animations =
b->getAnimationList();
for (osgAnimation::AnimationList::iterator it =
animations.begin(); it != animations.end(); ++it)
{
osg::notify(osg::FATAL)<<"playing animation:
"<<i<<std::endl;
(*it)->setPlayMode(osgAnimation::Animation::LOOP);
_am->playAnimation(*it);
osg::notify(osg::FATAL)<<"animation name:
"<<(*it)->getName()<<std::endl;
osg::notify(osg::FATAL)<<"animation duration:
"<<(*it)->getDuration()<<std::endl;
i++;
}
return;
}
}
traverse(node);
}
};
And tried with a simple FBX model, but animation do not play.
Thanks.
Alessandro
