4-player snake with AI
~VANILLA~
16,523 logic gates
Just hop in a seat and start playing with WASD. When you get out of the seat, the AI will take control. So every snake can be either player or AI controlled.
controls
WASD: control snake
1: spawn your snake
2: spawn all snakes

fun technical facts
– the AI is very simple, it just goes towards the fruit and avoids walls directly in front and next to it’s head
– the screen is 20×20 pixels and every pixel is 2×2 with RGB colors
– the snakes move at 1.25 Hz so every 0.8 seconds
– this build is very close to being too big for the lift to spawn, just 4 extra wires would be too much
– the AI controller, head coordinate demux, screen logic and fruit coordinate comparators are all pipelined, meaning that all the snakes use the same logic for those functions, but in turns
– there’s a couple bugs that I couldn’t fix anymore due to lift spawn limit, like head on collisions being survivable and snakes getting infinite length sometimes
– the AI snakes can only see 1 pixel next to their head so they only avoid obstacles right next to them, this also makes them very prone to head on collisions because 2 snakes can move to the same pixel without seeing each other… fortunately they can survive it 😉
– tho there’s 2 fruits, the AI snakes only go after one of them, blue and pink snakes go for the same one, and red and yellow go for the other
– fruits can’t spawn inside snakes, well they actually can but just try again if that happens, that is why sometimes the fruit has to spawn multiple times before they find a spot
– every snake has a unique sound when turning, when they all turn they make a nice melody of E B c# A
