TinyECS

Another Entity-Component-System, written in Rust.

• simple components createion: struct Position { x : i32, y : i32, z : i32 } impl Component for Position {}

• simple entities creation:

``` let mut entitymanager = world.entitymanager(); let entity = entitymanager.createentity();

entity.addcomponent(Position {x : 0, y : 0, z : 0}); entity.addcomponent(Velocity {x : 1}); entity.refresh(); ```

• simple macro for systems creation: process_entities!((MoveSystem): |pos: Position, vel: Velocity| => { pos.x += vel.x; println!("Moving! position: {}, velocity: {}", pos.x, vel.x); });

• or without macroses: ``` pub struct MoverSystem; impl System for MoverSystem { fn aspect(&self) -> Aspect { aspect_all![Position, Dead] }

  fn processone(&mut self, entity : &mut Entity) { let mut pos = entity.getcomponent::(); let vel = entity.get_component::(); // no problems with multiple mutable components

  pos.pos.x += vel.x;
  

  } } ```
