Hello with my player controller script I want it to move 1.5 when going up, down, left, or right. Also I want it so the player can't go diagonal. How would I do that?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerControllerScript : MonoBehaviour
{
public float moveSpeed = 5f;
public Transform movePoint;

// Start is called before the first frame update
void Start()
{
    movePoint.parent = null;
}

// Update is called once per frame
void Update()
{
    transform.position = Vector3.MoveTowards(transform.position, movePoint.position, moveSpeed * Time.deltaTime);

    //Checks if movePoint and player are together to make the movement
    if (Vector3.Distance(transform.position, movePoint.position) <= .05f)
    {
        // Left and Right Movement
        if (Mathf.Abs(Input.GetAxisRaw("Horizontal")) == 1f)
        {
            movePoint.position += new Vector3(Input.GetAxisRaw("Horizontal"), 0f, 0f);
        }

        // Up and Down Movement
        if (Mathf.Abs(Input.GetAxisRaw("Vertical")) == 1f)
        {
            movePoint.position += new Vector3(0f, Input.GetAxisRaw("Vertical"), 0f);
        }
    }

}

}

change
if (Mathf.Abs(Input.GetAxisRaw(“Vertical”)) == 1f)
to
else if (Mathf.Abs(Input.GetAxisRaw(“Vertical”)) == 1f)
