I am following the tutorial here and am running into an error (image below). This is happening after using gdrl within a conda environment on windows (second image). Please let me know if there is any further information I can provide.

It is possible that you need to add the AIController3D to a group called "AGENT". If you need more details on how to do this I can provide them. I will add this information to the tutorial as soon as I can.

kasmith11 commented 1 year ago

@edbeeching , since I'm newer to Godot and godot-rl could you provide more detail? Also, would it be helpful for me to add this information to the tutorial via a pull request once we figure out the solution?

edbeeching commented 1 year ago

@kasmith11 , sure. Click on the AIController3D, then on the top right you can add it to the agent group like this: image

I think a newer version of the plugin should do this automatically, I just need to push an update.

Let me know if that works.

@edbeeching Adding the agent group fixed the error I was running into! Thank you.

My thinking now is that I can add your directions to this file here including what you mentioned above as a small note under this section:
