Ziggy's Game of Life

Conway's Game of Life in Zig.

game-of-life-demo.webm

Made in a couple pairing sessions at Recurse Center.

Building

Supports Windows and MacOS. If using MacOS, make sure SDL2 is installed in your /Library/Frameworks path.

zig build
zig-out/bin/zgol.exe <args>
# Alternatively you can just use the run step
zig build run -- <args>

Examples

Try loading an example with

zgol -load=examples/<filename>

Because the grid is represented as a binary array, you can load any arbitrary data! Try loading the executable with

zgol -load=zgol.exe

Usage

Use -help to see CLI commands.

Input	Action
Left Click	Fill Cell
Right Click	Erase Cell
Space	Toggle Simulation
+	Increase Update Speed
-	Decrease Update Speed
R	Reload file (if any)
S	Save file

Saving will always create a new file in <exe-directory>/saves, named by the current timestamp. Reloading will attempt to load the latest save or the inital -load file.
