HI,

I am struggling with a really easy problem. I declared :

geometry_msgs::Pose pose_msg;

I am trying to assign x y z coordinates in one line instead of doing:

pose_msg.position.x = 0.0;
pose_msg.position.y = 0.0;
pose_msg.position.z = 0.0;

I would like to do something like:

pose_msg.position = (0.0,0.0,0.0)

Sorry if the question has been already asked but for me, it was hard to find an answer online.

Thanks in advance for your help

With the default messages, this is not supported.

With the merge of ros/gencpp#32 this is now possible (after gencpp version 0.6.0 has been released), but will need custom code.

See wiki/roscpp/Overview/MessagesSerializationAndAdaptingTypes - Customizing generated message headers for C++ for more info on this.
