Manually set a node to subscribe to a topic [closed]

Hi there!

I was wondering is there any way I can manually make a node to subscribe to a topic?

By checking rqt_graph, the node didn't subscribe to the topic (which I need to set) automatically.

Thanks!

Maybe you should look at this: link text

Go to the line 75 of the subscriber node code, and that's what you have to add to the code of your node to subscribe to a specific topic.

I tried. It displays only the message. I can't set by doing that. Thanks for your input!
