15:39 For anyone watching in 2022 getting errors, you need python version 3.9.10 for mlagents-learn to work. If you have a later version, you can install the earlier version (without adding it to the path) and use virtualenv to make a virtual environment using the older python version. You may need to also do pip install torch once in the venv, as it is a dependency of mlagents. Took me a lot of googling to figure this out so hopefully this helps others :)

Great video !!
For the raycast radius what it does is help you detect small objects by making the radius bigger you will actually have more chances of getting a hit when going by a small object instead of just missing it.

thanks for the awesome tutorial! How long did you leave the AIs running for before they learnt enough? I've left mine learning for 2 hours with 4.1mil steps and yet it still can barely make it past the first couple. All my other settings are basically the same as yours except for the rays I had 10 instead of 8. Am I missing anything, or does it really just take that long to learn?

Is there any way to train the bird inside the unity editor without having to use the python things.

Like if I wanted to make a mobile game where you trained your own flappy bird in-game would I be able to do that?

Great vid BTW :)

Great video! Is there any way to use this to determine if the level is too difficult or too easy? Then to figure out if the pipes need to be spawned further apart or closer together, or the gap to be increased or decreased?

Thanks for the tutorial. Helped a lot! And as always, I learned that the details are important... I missed the part where the bird is sat with a collider as a trigger, so it kind of didn't work as a start.
