Hi all, We want to inform you that we will ship the 3DBall example as a Sample in the com.unity.ml-agents C# package at version 1.9.0-preview. We want to ask you which samples you’d like to see included moving forward to understand which example environments our users find most useful. We want to note that there are a couple of tradeoffs to having more samples or fewer samples: The more samples we add to the package, the bigger the size of the package will be. This will impact install and download times when installing ml-agents from the package manager. On the other hand, having more samples means people can access more of what ML-Agents offers without cloning the git repository. Having a smaller set of samples will reduce download and install times but at the cost of having users need to leave the Unity Editor to explore more of what ML-Agents offers. Please help us figure what is important to you as our users by responding to this thread. Cheers! The ML-Agents Team.
