system plugin: callback function never triggered?

asked 2018-10-20 21:28:50 -0500

This post is a wiki. Anyone with karma >75 is welcome to improve it.

Here is my code following tutorial:

void GazeboScenePlugin::Init()
{
  this->updateConn = event::Events::ConnectWorldUpdateBegin(
        std::bind(&GazeboScenePlugin::cameraService, this));

}

bool GazeboScenePlugin::cameraService()
{
  std::cout<<"!!!!!!!!!!!!!!!!!!!!!!!!!\n";
}

The code somehow never print as I expected. Why is that?

My project compiled with no problem and it was successfully loaded according to some other printed info not listed here. So I guess it might not be this problem... Thanks
