 * Used to attract Rigidbodies towards the position of this component.

 * @example Attractor component attracting a Rigidbody
 * ```ts
 * const attractor = object.addComponent(Attractor);
 * attractor.strength = 5; // positive value to attract
 * attractor.radius = 10; // only attract within 10 units
 * attractor.targets.push(rigidbody); // add the Rigidbody to be attracted
