Hello every one
I want to change position and size of a link programmatically.I tried this code below but when I run it, it gives this error.
THE ERROR
gzserver: /usr/include/boost/smart_ptr/shared_ptr.hpp:418: T* boost::shared_ptr<t>::operator->() const [with T = sdf::Param]: Assertion `px != 0' failed.
THE CODE
physics::LinkPtr link=this->model->GetLink("box");
sdf::ElementPtr sdflink=link->GetSDF();
sdflink->GetAttribute("name")->Set ("newName");
sdflink->GetElement("pose")->Set(
math::Pose(math::Vector3(-3, 0, 0), math::Quaternion(0, 0, 0)));
link->UpdateParameters(sdflink);
What should I do? Thank you in advance!
