your english is not very clear but from what i understood u want to throw a ball at the direction of the camera so all u have to do is to
vector3df targertpos=camera->gettarget()
and then take the z and x direction of the ball !

Code: Select all
vector3df NormalizedCameraZAxis = (Camera->getTarget() - Camera->getPosition()).normalize();
