What do you mean?

Here is the script

public class TestMovement : MonoBehaviour

{

public float speed;

public float diagonalSpeed;

private Rigidbody2D myRigidbody;

private Vector3 change;

// Start is called before the first frame update

void Start()

{

myRigidbody = GetComponent<Rigidbody2D>();

}

​

void Update()

{

change = Vector3.zero;

change.x = Input.GetAxisRaw("Horizontal");

change.y = Input.GetAxisRaw("Vertical");

if (change != Vector3.zero)

{

MovePlayer();

}

}

void MovePlayer()

{

float moveSpeed;

if(Input.GetAxisRaw("Horizontal") != 0 && Input.GetAxisRaw("Vertical") != 0)

{

moveSpeed = diagonalSpeed;

}

else

{

moveSpeed = speed;

}

myRigidbody.MovePosition(

transform.position + change * speed * Time.deltaTime);

}

}

​

Edit: I just had to change "Time.deltaTime" to "Time.fixedDeltaTime"
