the very clear tutorial. Is there a way to give sendGoal callbacks that are

<p class=MsoNormal style='margin-bottom:12.0pt'>Hi Ben,<br>
<br>
I'm sorry that you're having trouble learning how to use actionlib. I
just put together a fairly short example of how to use the simple action client
callbacks:<br>
<a
href="http://www.ros.org/wiki/actionlib_tutorials/Tutorials/Writing%20a%20Callback%20Based%20Simple%20Action%20Client">http://www.ros.org/wiki/actionlib_tutorials/Tutorials/Writing%20a%20Callback%20Based%20Simple%20Action%20Client</a><br>
<br>
Hopefully this will give you something to build off of. If it doesn't
answer your questions, please let me know, and I can try iterating on the
example.<br>
<br>
Good luck,<br>
Vijay<o:p></o:p></p>
