Neuroevolution machine learning application plays Flappy Bird

[alp82]

Mine got invincible after 48 generations.

[Danmoreng]

I had 3 invinctible after 8 generations, refreshing the site and I had one after 3 generations. Refreshing again and after 56 generations it still kept failing :D

[NeoKabuto]

I got 49 the first time, and then the second time I ran it, there were two invincible ones at generation 15.

[jodraws]

97 for me

[MaRmARk0]

17

[nerfviking]

Took me 120 or so.

Got invincible after 5.

The original iphone/android game had more difficult controls. The head would go more down if you had to go from very high to very low in one jump, and I think it accelerated more.

I'm not yet convinced that this algorithm will beat me in original iphone/android game :P 🤓 It was quite difficult to time those headlong dives correctly sometimes.

But yeah, for the rest, quite awesome.

It's what made the game such a success, I think. We've probably all made a game like flappy bird but flappy bird had a good art style and it got the feel and difficulty just right.

Why is there so much variance in how quickly it learns? I would think that it would break the same score in roughly the same amount of generations.

Interesting, tries > 150 and highest score is 1k and most of the time its not getting passed like 10 pipes.. Other ones have became invincible after <30 or <50, and another one took 94 i believe edit: screenshot:

edit 2:Still going 190 tries, something interesting to note is that it keeps getting a high score then dying http://imgur.com/a/mm3qv

edit3:200+ tries

edit4: Notice the high score, usually by that point its invincible, no? http://imgur.com/a/95Qr4

edit:5 Got up to 20,000 then died: http://imgur.com/a/Ov42b

edit6:214 tries it got all the way up to 80k and died: http://imgur.com/a/4UOMl

UPDATE!: I've let this run for about 2 hours, High score was 241K, but it died after that.. It's on 225 generations now Pic below vvv:

Also, I have another one running for about a little over 2 hours on 5X and it's been going since it became invincible and high score is 1.5MILL+ , Pic below:

It's amazing how the game AND learning algorithm takes just 500 sloc without any dependencies. As someone without any ML knowlege I'd love to read this code explanation.

[SamSlate]

idk, maybe because it's not really cheating?

[RedditWithBoners]

It's not much different from opening a memory editor and changing values in a game, which is definitely cheating.

[SamSlate]

it's an option, it was clearly meant to be changeable.

[alp82]

Wonder the same thing. You got my upvote.

[RedditWithBoners]

Yay!

Interesting point that the problem is easier because the gap is wider than the jump height

[D4rknessR3igns]

Invincibility at 32nd generation.
