tecs

TeaECS is a simple Rust ECS. I'm building this project for learning purposes.

This project doesn't have the ambition to be as good or better than popular ECS libraries such as Legion or Specs. It is however heavily inspired by them.

The entities' data are stored in unique Vecs (one for each component type).

tecs doesn't provide parallel processing features.

Creating entities

let mut ecs = Ecs::new();
let entity_id = ecs.new_entity()
    .with_component(Position { x: 0.5, y: 0.3 })
    .with_component(Speed { x: 1.0, y: 2.0 })
    .build();

Removing entities

ecs.remove_entity(1);

Querying the Ecs

let mut ecs = Ecs::new();
ecs.new_entity()
    .with_component(Position { x: 0.5, y: 0.3 })
    .with_component(Speed { x: 1.0, y: 2.0 })
    .build();
ecs.new_entity()
    .with_component(Position { x: 1.2, y: 2.2 })
    .with_component(Speed { x: 0.5, y: 0.1 })
    .build();

for (position, speed) in <(Mut<Position>, Imm<Speed>)>::iter(&mut ecs) {
    position.x += speed.x;
    position.y += speed.y;
}
