Help to How to Dash with Rigidbody3D

Hello! I'm trying to do a mechanic for my demo game but I got stucked at the dash movement. I've made an isolated script that uses a coroutine in order to get a smooth transition, but nothing happens. I appreciate any help. Here it is:

public class PlayerDash : MonoBehaviour
{
[SerializeField] float dashSpeed = 0.5f;
[SerializeField] float dashDistance = 2f;

new Rigidbody rigidbody;
Vector3 movement;

IEnumerator currentCoroutine;

void Start() {

rigidbody = GetComponent<Rigidbody>();
}

private void Update()
{
movement = new Vector3(Input.GetAxisRaw("Horizontal"), 0, Input.GetAxisRaw("Vertical"));

if (Input.GetKeyDown(KeyCode.Space))
{
if (currentCoroutine != null)
{
StopCoroutine(currentCoroutine);
}

currentCoroutine = Dash(movement);
StartCoroutine(currentCoroutine);
}
}

IEnumerator Dash(Vector3 movement)
{
Vector3 destination = transform.position + movement * dashDistance;

float remainDist = (transform.position - destination).sqrMagnitude;

while (remainDist > float.Epsilon) {

Vector3 newPos = Vector3.MoveTowards(transform.position, destination, dashSpeed * Time.deltaTime);
rigidbody.MovePosition(transform.position + newPos);

remainDist = (transform.position - destination).sqrMagnitude;

Debug.Log(transform.position);

yield return null;
}
}
}​

 

Nevermind, i made it.
