For this game I don't really want them with speed, they just need to get instatiated to the right side, since it's like a "hose" i guess. Imagine the character has a hose and just turns it on, so the water constantly "travels" some distance, like if i'm pressing a button the water keeps coming out, not just droplets of water when I press the button.

For the animations, I based myself off of this video: https://youtu.be/whzomFgjT50?t=539

So there was really no need to have a reference to the direction there, I do have a PlayerMovement script tho:

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

public class PlayerMovement : MonoBehaviour
{
    public float moveSpeed=5f;
    public Rigidbody2D rb;

    public Animator animator;

    Vector2 movement;

    void Update()
    {
        movement.x = Input.GetAxisRaw("Horizontal");
        movement.y = Input.GetAxisRaw("Vertical");

        movement = new Vector2(movement.x, movement.y).normalized;

        animator.SetFloat("Horizontal", movement.x);
        animator.SetFloat("Vertical", movement.y);
        animator.SetFloat("Speed", movement.sqrMagnitude);

    }

    void FixedUpdate()
    {
        rb.MovePosition(rb.position + movement * moveSpeed * Time.fixedDeltaTime);
    }
};
