Platform support
This project curretly supports Ubuntu 18.04. Windows 10 was supported in an earlier versions of this project, but is not yet available in the standalone version. It should be possible to get it working on other systems as well.
How can I try this out?
Clone this repo and open the Unity Project using the Unity Hub.We plan to make this be available as a .unitypackage and in the Unity Asset Store as soon as possible.
Installing Unity
Install Unity through Unity Hubhttps://forum.unity.com/threads/unity-hub-v-1-6-0-is-now-available.640792(the download link changes sometimes, so look at the newest posts)
After downloading Unity Hub install Unity Editor. Follow this instruction https://docs.unity3d.com/Manual/GettingStartedInstallingHub.html When choosing a version, choose the latest stable one. During installation, wait until the blue line is complete.
Building custom interfaces/messages
Clone https://github.com/samiamlabs/ros2_dotnet (cyclone branch) and run the script create_unity_plugin.bash to build/generate a “Plugins” folder for Unity from source.This script requires that you have docker installed on your system permissions setup to run it without sudo. See https://dyno-system-config.readthedocs.io/en/latest/docker.html
If you want some custom messages included in the prebuilt binaries, you are welcome to submit a pull request with a ROS2 package containing the interfaces/messages to https://github.com/DynoRobotics/rcldotnet_custom_interfaces
To build custom messages yourself, you will need to add the packages containing them to https://github.com/samiamlabs/ros2_dotnet/blob/cyclone/ros2_dotnet_dashing.repos and https://github.com/samiamlabs/ros2_dotnet/blob/cyclone/rcldotnet_utils/rcldotnet_utils/create_unity_plugin.py before running the build script. Note that all the .so files need to be set to preload at startup in Unity. (Can be selected in a checkbox in the “inspector” window)
