Vincent, Have your tried deriving your class LightMoveCallback from osg::NodeCallback instead of osg::StateAttribute::Callback to see if the callback gets called?
Just a thought... -Shayne -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Vincent Bourdier Sent: Thursday, August 07, 2008 8:56 AM To: osg Subject: [osg-users] light Callback Hi, I just need to move a light, and for that I try to use a callback. So I implement a simple class lightMoveCallback : public osg::StateAttribute::Callback with virtual void operator()(osg::StateAttribute* ss, osg::NodeVisitor* nv); but the callback is never called... I use : light->setUpdateCallback(new lightMoveCallback()) thanks for help, Regards, Vincent.
