Time for action – moving the Rigidbody component

Use the following steps to move and rotate the Rigidbody component:

1. Add in the following code to PlayerBehavior underneath the Update method, and then save the file:

// 1
void FixedUpdate()
{
    // 2
    Vector3 rotation = Vector3.up * hInput;

    // 3
    Quaternion angleRot = Quaternion.Euler(rotation *
        Time.fixedDeltaTime);

    // 4
    _rb.MovePosition(this.transform.position +
        this.transform.forward * vInput * Time.fixedDeltaTime);

     // 5
     _rb.MoveRotation(_rb.rotation * angleRot);
}

Here's a breakdown of the preceding code:

1. Any physics- or Rigidbody-related code always goes inside FixedUpdate, rather than Update or the other MonoBehavior methods:
   
   • FixedUpdate is frame rate independent and is used for all physics code. 
2. Creates a new Vector3 variable to store our left and right rotation:
   • Vector3.up * hInput is the same rotation vector we used with the Rotate method in the previous example.

3. Quaternion...
