Game Of Life Rules : A board with equal size square boxes called cells. Each cell is alive when its bright and dead when its not. For a cell to be alive it must have 2 or more neighbouring cells that are alive too else it dies. If it has one alive neighbour it dies, no neighbour, it dies. A cell is born when a cell has exactly three live neighbours. So usually, this is played in a infinite universe and an infinite environment space with unlimited memory and computing power that none of us has access to so building it on a periodic-repeating single plane universe when the edges are connected to its parallel ones. Langauges: Rust, WebAssembly and Javascript the only god tier languages I know in existence Why Javascript? can directly read and write to WebAssembly limear memory space Garbage-collector heap considers and returns scalar What is wasm_bindgen used to box Rust structures wrapping pointers in javascript class for usability basically clears boundries Game Plan Well, here comes the binary! the best part. The whole universe is mapped cell to byte into a flat one dimensional array where the live cell is represented by 0 and a dead cell is represented by 1. Consider a 4 x 4 universe : 16 cells in total mapped into an flat array looks like this → count index 0 How is it mapped? good question! An index function is used to allocate the cell environment into a byte memory reserved in the universe like this: index(row, column, universe) = row * width(universe) WebAssembly LIner Memoy ?→ Rust String → Javascripts Garbage collector Heap → HTML textContent code source As you notice, a macro #[repr(u8)] is used so as to represent each cell with a single byte.
