Snake in Factorio - Combinator Contraptions

[ZachAttackary]

I noticed that there are not many people creating cool stuff with the combinators in factorio. They are infinitely more powerful than redstone in minecraft, yet the coolest thing I could find on the web was your scrolling sign or the christmas light show. I spent the last 10 hours or so making snake in factorio! Check it out and let me know what you think of it!

You didn't search enough : viewtopic.php?p=139707#p139707

Oh man, that is awesome! I most definitely did not search enough! Thanks for the link!

I am wondering, how many combinators have you used to make this snake?
Because I see about 150 comb only on your screen, and for some reasons I think this is not the whole system.

Very interesting! Shooting the constant combinators was pretty smart solution for controlling the game. Similarly I'm working on timing a racetrack and the best solution I could come up with in vanilla was crashing the car into power poles to disconnect a signal.

What I'm most interested in the build is how you made the RNG to control where the apple is placed. I've struggled with making a pseudo RNG and I've gotten nowhere.

And I think that theres a lot more combinator contraptions on here than you realize, but everything is so spread out they're hard to find.

Does anyone want to take part in snake competition?
Goal is to build snake using as few as possible combinators.

It ended up being about 500 combinators. What you are seeing in the picture is just the screen controller and a bit of the snakes memory. I am sure it can be done way more efficiently, this was just my first attempt at combinators. If you watch the video, I show everything near the end.

Thanks! I was pretty proud of the controls As for the RNG, I kind of cheated and didn't bother making a true SRNG, all I did was have a counter running through all of the screen pixels, and when I ate an apple, what ever that counter was currently on, it put the next apple there. If it would place the apple on the snake, it waits 1/6th of a second and trys again, until it finds a valid apple placement. Since the game clock is variable(as you eat apples, it speeds up), the counter and the game clock never really line up, so it creates a random affect quite nicely.

And for those of you curious, the game speed maxes out at about 12 changes per second, way faster than a human can control. I have it slowed down a ton in order to be playable haha

Hmmmm....
I think it is possible to make 10x10 snake in 40-70 combinators, and definitely with 20-30 changes per second.

Oh I'm sure you could. Like I said, this is my first project with combinators, I am by no means an expert!
