make a GameObject perfectly copy another GameObject's position with AddForce?

Does anyone know how to make a GameObject perfectly copy another GameObject’s position with AddForce? (MovePosition causes massive stuttering for some reason.)

This causes it to follow the original object with a delay, rather than exactly be on top of it.

 private void FixedUpdate() {
       rb.AddForce(targetTransform.transform.position - this.transform.position, ForceMode.Acceleration);
}

In case anyone’s curious, the stuttering MovePosition code is:

  private void FixedUpdate()
    {
        rb.MovePosition(targetTransform.position);
        rb.MoveRotation(targetTransform.rotation);
    }
}

It causes the object to fly and blink around rapidly even though it’s the only Rigidbody in the scene and even if I choose ‘Interpolate’. Crazy stuff. So that’s why I’m trying to use AddForce instead…

It’s moving like that because MovePosition with “Interpolate” moves it smooths between frames, it’s not a “go here smoothly over time” function.

try this

        rb.MovePosition((targetTransform.position - myTransform.position).normalized * speed * deltaTime);
