I meant to share this on my 6 year anniversary on scratch but I forgot. Oops. Cellular automata are a type of 0 player game where you make a layout and let it run. In these games, cells will either be on or off, and that state will be determined by the 8 cells around them and updated next frame. Here are the rules for some. Make sure to check the presets to learn more about the automata. ---Conway's Game of Life (life)--- (black=alive, white=dead) This is the quintessential cellular automaton. It has very simple rules, but can be used to make some really cool things. rules: if a live cell has 2 or 3 other live cells around it, it survives, or else it dies. If a dead cell has 3 live cells, it comes back to life ---Day and Night (day)--- (orange=alive, black=dead) This is considered a life like automata, meaning the cells die and come back to life based on a set number of live/dead cells around them. This one is interesting because the live and dead cells act the same. rules: if a live cell has 3, 4, 6, 7, or 8 other live cells around it, it survives, or else it dies. If a dead cell has 3, 6, 7, or 8 live cells, it comes back to life ---Seeds--- (white=alive, black=dead) This is also a life like automaton. It's very chaotic and tend to expand a lot. Rules: all living cells die each frame a dead cell comes back to life if it has 2 live cells around it ---Brian's Brain (brain)--- (white=alive, black=dead, blue=dying) This one is a generations type automaton. This means when a live cell dies, that cell can't come back to life for a set number of frames (represented by a new color). This one is a simple one based off seeds. rules: all live cells die each frame dead cells come back to life if they have 2 neighbors when a cell dies, it turns blue. blue cells turn into dead cells next frame ---Wireworld (wire)--- (orange=wire, black=void, blue=head, white=tail) This is a simulation where electrons move through wires and can complete various logic functions. rules: a wire will turn into an electron head if it has 1 or 2 electron heads around it electron heads turn into tails tails turn into wires. (tails prevent it from going backwards) Honorable mentions (mostly didn't add cuz not important/too complicated): highlife (B36/S23) diamoeba (B35678/S5678) replicator (B1357/S1357) stains (B3678/S235678) vote (B5678/S45678) langston's loops (automaton with complex rules that allow for programs to be scripted) cyclic automata (3 types, each change based on if there is 3 of one of the others) conway's automaton (the first cellular automaton) cell machine (pretty much the only one made as a game)
