callbacks will only be called from ros::spin(Once) or by manually calling the callback-queues to be processed.

Unless you use some kind of threading the function will finish and the other callback will be called in the next loop.

I'm thinking of having a node send a message to another node as part of a callback function. It should receive a message from another node at about this time as well, before it finishes the callback function. What will ROS do in this case? Will the node pause the first callback function in order to execute the second, or will it finish executing the first callback before executing the callback function for the message it just received?

Thanks!

I got Player and ROS to integrate without the Player package, with ROS Diamondback and Player 3.0.2.

Instructions are here: http://brice-rebsamen.blogspot.com/2011/05/first-exercise-with-ros-node-to.html

The key is to edit the CMakeLists.txt file so that ROS finds all of the Player libraries that are installed during compilation.

I want it to support a Logitech Quickcam Orbit/Sphere AF. Currently, I have the camera working and functioning in a Player program.

Hi,

I am trying to use the "Player" package with a package that I am working on, but I can't seem to find any documentation telling me how to use that package.

Right now, I have "player" listed as a dependency in my manifest.xml file of the package I'm writing, and that's it. Running "cmake ." in the directory doesn't give any errors. Running "make" tells me that it's not finding any Player packages.

Is there something I'm missing in CMakeLists.txt?

Thanks!
