I’m very new to Unity and am trying to set up 8 directional movement and animation for my Sprite. At present, 4 directional movement (up, down, left, right) is working fine, but diagonal movement is not working for all but one direction. This is what happens:

Press Right + Down: Right walking animation (correct)
Press Right + Up: Up walking animation (incorrect, I want Right Walking animation)
Press Left + Down: Down walking animation (incorrect, I want Left Walking animation)
Press Left + Up: Up walking animation (incorrect, I want Left Walking animation)

In summary, if travelling horizontally I want to favour the horizontal/x axis animation.

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

public class Movement : MonoBehaviour
{
    public float speed;
    public Animator animator;

    
    //get input from player
    //apply movement to sprite 

    private void Update()
    {
        float horizontal = Input.GetAxisRaw("Horizontal");
        float vertical = Input.GetAxisRaw("Vertical");

        Vector3 direction = new Vector3(horizontal, vertical);

        AnimateMovement(direction);

        transform.position += direction * speed * Time.deltaTime;
    }

    void AnimateMovement(Vector3 direction)
    {
        if (animator != null)
        {
            if(direction.magnitude > 0)
            {
                animator.SetBool("isMoving", true);
                animator.SetFloat("horizontal", direction.x);
                animator.SetFloat("vertical", direction.y);
            }
            else
            {
                animator.SetBool("isMoving", false);
            }
        }
    }

}
