Dear colleagues, could you demonstrate a minimal working example with G4VUserTrackInformation? The “extended/runAndEvent/RE01” is too large to catch the point. When I try something like
class TI : public G4VUserTrackInformation
{
public:
string s;
};
....
void GGSteppingAction::UserSteppingAction(const G4Step* step)
{
G4Track * theTrack = step->GetTrack();
if(theTrack->GetUserInformation())
{
cout<<((TI*)theTrack->GetUserInformation())->s<<"\n";
}
else
{
TI *tt=new TI;
tt->s="test";
theTrack->SetUserInformation(tt);
}
}
it doesn’t work.
