Hi Steven-
I don't think there is. I wrote myself a helper file with a bunch of functions to populate and return a variety of message objects like that so I could do it in my main code in a single line.
e.g.
std_msgs::ColorRGBA createColorMsg(double red, double blue, double green, double alpha)
{
std_msgs::ColorRGBA color;
color.r = red;
color.g = green;
color.b = blue;
color.a = alpha;
return color;
}
It seems like a collection of functions like this would be very helpful in general, but I'm not sure where it should live. It seems the best solution would be if each message type included such a function with it, or better yet, a constructor that supported this, but that would imply some additional automation in the message generation script...To the ROS devs: How hard would it be to make the message generation step include an overloaded constructor for each message type that could take in values?
