Hello, What I want to do is something similar to a raycast. From a specific position draw a line and get the list of all the free cells in that line. The line has a maximum length, but it has to stop if it reach an obstacle. Is there an existing API for that? Or I need to implement it myself?

Thanks!

I see, thank you.

Is there any future plan on extending the shutdown procedure and give to the developers more control over it?

Thank you for the suggestion, but what I'm trying to do is different.

2016-12-22 09:29:52 -0600 asked a question Node shutdown

Hello,

I'm working on a node with an internal state machine. The node has to run the main loop in the "running" state, then after using Ctrl+C (or sending a rosnode kill) switch into a "closing" state do some stuff (maybe ROS related, like publishing on a topic) and then shutdown completely. In synthesis, I need to break the main loop without using ros::shutdown().

Currently I'm using an implementation similar to the one suggested here: http://answers.ros.org/question/27655...

Is this one still the best (and probably only) approach? Or there is a way to "split" the shutdown procedure?
