Shipyard

Shipyard is an Entity Component System. While it's usable it is far from finished.

Interesting features

• Packing can enable perfect components alignment, allowing fast iteration but also SIMD instructions. To learn how it's done read Michele skypjack Caini's great blog article.
• Automatic scheduling you just have to tell which systems you want to run and the World will do the rest.

Simple Exemple

use shipyard::*;

struct Health(f32);
struct Position { x: f32, y: f32 };

struct InAcid;
impl<'a> System<'a> for InAcid {
    type Data = (&'a Position, &'a mut Health);
    fn run(&self, (pos, mut health): <Self::Data as SystemData>::View) {
        for (pos, health) in (&pos, &mut health).iter() {
            if is_in_acid(pos) {
                health.0 -= 1.0;
            }
        }
    }
}

fn is_in_acid(pos: &Position) -> bool {
    // well... it's wet season
     
    true
}

let world = World::default();

world.new_entity((Position { x: 0.0, y: 0.0 }, Health(1000.0)));

world.add_workload("In acid", InAcid);
world.run_default();
