You'll need to call colcon build after you change the yaml file. (after step 2 in your steps described)

It seems like multi-agent mode is in different branch and run in ROS Melodic. Could you clarify it? @hzheng40

hzheng40 commented 1 year ago

No it runs in the same branch.

I checked it again and I had to add a new node in rviz to see it. Thanks.
