Re: [osg-users] Problem with animation in .osgb files
In my code animation play with space key(in .fbx and .dae files), but in osg native formats I can't control it - animation play once without pressing key and AnimationManagerFinder is empty. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=58445#58445 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Problem with animation in .osgb files
Hi, everyone
I am new in OSG and have a problem. I wrote the code that plays animation in
.fbx models, but I can't play animation in .osgb(.osgt, .ive) models. Please
see the attached file and help me.
P.S. Sorry for the clumsy English(
Thank you!
Cheers,

Re: [osg-users] Problem with animation in .osgb files
my very old code used osg::AnimationPathCallback
.
class FindAnimationVisitor : public osg::NodeVisitor
{
public:
FindAnimationVisitor():
osg::NodeVisitor(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN)
{
//apc=NULL;
setTraversalMask(0x);
setNodeMaskOverride(0x);
}
//найденные анимации
typedef std::vector osg::ref_ptrosg::AnimationPathCallback NodeList;
NodeList _foundNodes;
//и соответственно объекты, содержащие эти самые анимации
typedef std::vector osg::ref_ptrosg::Transform TransformList;
TransformList _foundTransforms;
virtual void apply(osg::Transform node);
virtual void apply(osg::Group group);
/*
virtual void apply(osg::MatrixTransform node);
virtual void apply(osg::AnimationPathCallback node);
*/
private:
//Путь анимации
//osg::ref_ptrosg::AnimationPathCallback apc;
};
void FindAnimationVisitor::apply(osg::Transform node)
{
//apc =
dynamic_castosg::AnimationPathCallback*(node.getUpdateCallback());
osg::ref_ptrosg::AnimationPathCallback test =
dynamic_castosg::AnimationPathCallback*(node.getUpdateCallback());
if (test.get())
{
//std::cout I find animation;
//Запоминаем анимацию
_foundNodes.push_back
(dynamic_castosg::AnimationPathCallback*(node.getUpdateCallback()));
//и объект к которому она прикреплена
_foundTransforms.push_back (node);
}
traverse(node);
}
void FindAnimationVisitor::apply(osg::Group group)
{
traverse(group);
}

Hi Maxim I tried your code, and it plays an animation from an .osgb file for me. Regards, Laurens. On 9/30/2013 2:18 AM, Maxim Voloshin wrote: Hi, everyone I am new in OSG and have a problem.
