Thanks man, this is useful stuff! I'm interested to try, but it's a shame it's not an all-in-unity solution, because then you could use the training during gameplay for a simulated pet style game (maybe including hamsters??? ;) )

Haha not a bad idea! :P

Perhaps they will roll it all into unity at some point. For now the industry standard ML tools all have a python interface so I guess thats why they externally communicate with python. I agree tho, if we could just pass those hyper parameters to a pre-defined PPO algo then feed the charts back into unity, that would lower the barrier of entry significantly.

I didn't quite understand the nibbles extension script and what it does.

It wasn't really necessary but it makes the code a little neater. It turns something that would look like this:

if ((int)action[0] == MoveLeft){}

into this:

if (action.Is(MoveLeft)){}

which I think is a little easier to read

thanks for the reply, I'm rather new to Machine learning with unity, I am having hard time figuring out what should be put in the CollectState() and AgentStep(). Where can I get more info on these?

I just want to train the agent so it pushes off a sphere from a plane.

You are best just to follow the balance ball example: https://github.com/Unity-Te...

it taught me alot

My pleasure! If only I can find time to do some more.
