Game of Life, in 3D, using Bevy

Recently released https://crates.io/crates/pipe-gpt and soon I will return to Game-Of-Life. Follow on X and Twitch for rust related content.

game-of-life's Issues

A naming convention for life rules

https://www.complex-systems.com/abstracts/v08_i01_a04/

bug: flickering when paused

There is evidence of a bug that needs investigating. When paused the game is flickering between render states.

Make game pausable

See: https://book.amethyst.rs/master/controlling_system_execution/pausable_systems.html

Optimization: Deliberate u8 overflow for universe size 256x256x256x6

Currently we have an if statement for every rule, checking if we are at the edge of the universe. This could be avoided if we have a deliberate overflow without an index out of range error. This would be possible for a universe of size 256x256x256 using a u8.

This is twice as big as our performant universes that top out at about 140^3 and so may need other performance improvements first before it is possible.

Add music to the game

At some point we may have a soundtrack. Here is some code for that.

use bevy::prelude::*;

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_startup_system(setup)
        .run();
}

fn setup(asset_server: Res<AssetServer>, audio: Res<Audio>) {
    let music = asset_server.load("sounds/Windless soundtrack.ogg");
    audio.play(music);
}

Objects disappear too early when close to camera

This appears to be a known issue being worked on in Amethyst

See amethyst/amethyst#2173

Optimization: Have 6 correctly rotated/positioned obj files

This reduces LOC, removes the need for several if statements, and a rotating transform in systems::life::create_life_xyz(). It would also remove the need to know which of the 6 tetras are being placed and so reduces function arguments to (x,y,z) from (n,x,y,z).

Config files need to be present or an obscure error is displayed

Currently several ron files need to exist in a config directory within the game of life.

If those files or the whooe config directory is missing, the game errors out with "The system cannot find the path specified".

Either improve the error message so it says how to fix it, or fix the production version to come with these files.

Types of tetrahedron

Hill's tetrahedron should be considered for their tessellation in 3D space http://maths.ac-noumea.nc/polyhedr/Hill_.htm
