Hello Danny,
I'm trying to move my camera forward and backward as the event of up/down key.
You're on the right track with your subclass of osgGA::GUIEventHandler. This class's handle() can set the camera's view matrix using camera->setViewMatrix() (or the convenience setViewMatrixAsLookAt()).
Alternatively, you can subclass from osgGA::MatrixManipulator, override the handle() method to calculcate the new camera position, and override the getInverseMatrix() method to return that movement. Have a look at the source for osgGA::TrackballManipulator for an example. Then you give that manipulator to your osg::View / osgViewer::Viewer using setCameraManipulator(). This is the way that new camera movement modes are implemented generally.
Hope this helps, J-S -- ______________________________________________________ Jean-Sebastien Guay [email protected] http://www.cm-labs.com/ http://whitestar02.webhop.org/ _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
