The moveposition function of rigidbody2d of unity2d solves the problem of people or screen jitter when moving

This is a 2d Rigid body movement function

public void controlHero()
    {
    
        if ((ETCInput.GetAxis("Vertical") != 0) || (ETCInput.GetAxis("Horizontal") != 0)){
    
            rigidbody2D.MovePosition(rigidbody2D.position+Time.fixedDeltaTime*new Vector2(ETCInput.GetAxis("Horizontal"),ETCInput.GetAxis("Vertical")) * speed );
        }
        // as everyone knows , When the character moves, multiply by Time.fixedDeltaTime, Equivalent to logic in FixedUpade Call in , Every interval 0.02s Move once ;
    }

I started with FixedUpdate() Call in , As a result, the character shook unexpectedly , It has been changed many times , Think it's not smooth enough to move , Only later did I know , Consider the following rendering of the camera , Generally, the camera follows LateUpdate in , And I used cinemachine Also in LateUpdate in , Decisively changed to in LateUpdate Call the mobile function in , No shaking .

 private void LateUpdate()
    {
    
        controlHero();
    }
}

Okay, put it on Update It's fine too
