bevy_life is a generic plugin for cellular automaton.
From the classic 2D Conway's game of life to WireWorld and 3D rules, the plugin is completely generic and dynamic.
See: - Game of life variations - Wireworld implementation
The main branch follows the released version of bevy (0.5) but I provide 3 useful branches to follow the new engine features:
- bevymain follows the main branch of bevy
- bevypipelinedrendering follows the pipelined-rendering branch of bevy to use the new rendering system
- spriteinstancing follows a branch (see #2642) with sprite instacing and batching for better performance.
You may add as many generic CellularAutomatonPlugin as wished, the lib provides some implementations like:
- GameOfLife2dPlugin
- GameOfLife3dPlugin
- ImmigrationGame2dPlugin
- ImmigrationGame3dPlugin
- RainbowGame2dPlugin
- RainbowGame3dPlugin
- WireWorld2dPlugin
- WireWorld3dPlugin
- CyclicColors2dPlugin
- CyclicColors3dPlugin
Then you may use bevy as usual and add impl Cell and impl CellState components to the entities.
The lib provides some implementations like MooreCell2d or MooreCell3d for cells and ConwayCellState, WireWorldCellState, etc for states.
You may implement your own cells (coordinate system) and states (rules) as you want, the cellular automaton system is completely dynamic and generic.
For more information yo may look at some examples.
No feature is required for the plugin to work and the main traits Cell and CellState are always available.
But you may enable the following features
2D (enabled by default): Enables 2D types like:
MooreCell2d (square cell with 8 neighbors)NeumannCell2d (square cell with 4 neighbors)HexagonCell2d (hexagon cell with 6 neighbors)GameOfLife2dPlugin, ImmigrationGame2dPlugin, RainbowGame2dPlugin, WireWorld2dPlugin, CyclicAutomaton2dPlugin3D: Enables 3D types like:
MooreCell3d (cube cell with 26 neighbors)NeumannCell3d (cube cell with 6 neighbors)GameOfLife3dPlugin, ImmigrationGame3dPlugin, RainbowGame3dPlugin, WireWorld3dPlugin, CyclicAutomaton3dPluginauto-coloring (Example or debug purpose):
CellStateMaterials resource to contain material handlesCellState type now requires to build a CellStateMaterialsCellState components with materials will be colored according to their type.This is probably not the fastest rust implementation of a cellular automaton in rust. For example, using Gosper's HashLife a classic game of life could be much faster.
This library aim is to be generic and dynamic, so that you can integrate cellular automata to any project in bevy, with any rules, in 2D or 3D.
For every example pressing space reloads the board
Run cargo run --example 2d_game_of_life --features auto-coloring
Run cargo run --example 2d_immigration_game --features auto-coloring
Run cargo run --example 2d_rainbow_game --features auto-coloring
Run cargo run --example 2d_cyclic_colors --features auto-coloring
Run cargo run --example 2d_wireworld --features auto-coloring
The example is dynamic, use the left mouse click to create a conductor cell on an empty space or to create an electron head
Run cargo run --example 3d_game_of_life --features "3D auto-coloring" --no-default-features
