About gazebo API about gap HOT 4 CLOSED

These functions are not exactly provided by Gazebo, but automatically generated by the Protobuf compiler from the .proto message. Essentially depending on the type of data field, you get different ways to change it. I think this may be useful to help understand which functions are created for different types of fields.
In any case, if you have compiled Gazebo from source you can see the generated .pb.h headers for each message type in the build/gazebo/msgs directory.

Cooooooooool! This is great to know. Thanks!

Thank you!

The contents of the Visual message are documented here, although .proto are not really supported by Doxygen, so usually looking directly at the code is usually more helpful. It doesn't really tell you which functions are implemented for adding or removing fields, but it is standard across Protobuf messages.

If instead you mean where did I find out that Gazebo listens to ~/visual topic and what it does with these messages, I'd say I was looking at the source and found this, specifically the Scene::ProcessVisualMsg function.

Thank you for your timely response!
I found .proto file once but there is no member functions related. I only shows the member variables. I found you are using function mutable_material()
That's so brilliant and I wonder if there is any place to know other similar member functions?
