Example

const movingEntitiesQuery = createQueryDefinition({
  with: ['position', 'velocity'],
  without: ['dead']
});

type MovingEntity = QueryResultEntity<Components, typeof movingEntitiesQuery>;

function updatePosition(entity: MovingEntity) {
  entity.components.position.x += entity.components.velocity.x;
  entity.components.position.y += entity.components.velocity.y;
}

world.addSystem('movement')
  .addQuery('entities', movingEntitiesQuery)
  .setProcess(({ queries }) => {
    for (const entity of queries.entities) {
      updatePosition(entity);
    }
  });
