How to simulate path planning in rviz

[allegorywrite]

Hi, I would like to simulate path planning using nav2 without using an actual UAV.
When I change the crazy_file_server node in multiranger_nav2_launch.py to sim backend node, it doesn't work correctly because I can't get odom frames. (That's obvious).
Is there any way to connect the crazyswarm2 simulator to nav2 without using a real machine?
thank you for your answer in advance.

hi! this has not been intergrated yet as we need to support an simulator that models sensors and such. I'v e been working on intergrating Webots but have hit difficulty with that ( you can see the discussion here: #176). However, i've done a super hackish thing in an experimental Repo: https://github.com/knmcguire/crazyflie_ros2_experimental that works with the webots simulator.

Me and @whoenig, talked and we have thought of an alternative solution for us to implement webots (or gazebo). I'll update the discussion soon.
