MC Game of Life Sim

Players spawn a grid of cells in the world and change each cell's state by interacting with it. After the grid is set up, a command begins the run, and each generation follows Conway's rules: a live cell with under two live neighbours dies of underpopulation, one with two or three live neighbours carries on, one with more than three dies of overpopulation, and a dead cell with precisely three live neighbours comes to life by reproduction. The mod also lets players watch how a pattern evolves step by step.

Cells are shown in alive, dead and gray states with adjustable colours and textures, and the grid can be reversed to run the simulation backwards. Breaking a block removes the whole grid, while right-clicking a block toggles its state between alive and dead. The mod is a Fabric port of the classic cellular automaton and needs no other mod, though it runs only where Fabric is installed.

The mod is published for Fabric alone, with files covering 1.20.3, 1.20.4, 1.20.5 and 1.20.6. The latest Fabric file is 1.0.1 for 1.20.6, released on 2025-01-18, and the project was first published on 2025-01-07.
