Real-time Visualization in Groot: is it included in the Basic package? about behaviortree.cpp HOT 6 CLOSED

from behaviortree.cpp.

Are you sure that publisher and tree_ don't go out of scope?
I am 90% positive that you are calling this inside a method and that publisher is destroyed immediately.

If that is the case, you may want to define an attribute in your class like

std::unique_ptr<BT::Groot2Publisher> publisher_;

and change your code to:

tree_ = factory_.createTreeFromFile(tree_file_path);
const unsigned port = 1667;
publisher_ = std::make_unique<BT::Groot2Publisher>(tree_, port);

from behaviortree.cpp.

It should work.can you tell me more about your error?

from behaviortree.cpp.

Certainly. So I fixed my code and it now compiles without error. I added these lines to my BT executor node:

tree_ = factory_.createTreeFromFile(tree_file_path);
const unsigned port = 1667;
BT::Groot2Publisher publisher(tree_, port);

I then run my BT executor, open Groot2, and select the "Monitor Mode" with Host: localhost and Port: 1667.

I then click on the "Connect" button, Groot thinks for some time, and then I get the message "Disconnected: Reply timeout".

Am I missing a step for connecting Groot to my running executor?

Thanks!

I don't understand, everything looks ok.

If you use the same code from tutorial 12, does it work?

from behaviortree.cpp.

This was exactly the problem. I tested it out and everything is working as expected. Thanks for the reply!
