I wrote the code in Unity hoping that the character can move in all directions in two dimensions if I press the direction key. (If I press the shift key, it moves fast.) However, after writing the code related to the animation, the character gets a bug that doesn’t move even if I press the direction key. I hope you can tell me a solution or a solution for someone with a similar problem.

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

public class PlayerManager : MonoBehaviour
{
    public float speed;

    protected Vector3 vector;

    public float runSpeed;
    private float applyRunSpeed;

    private Animator anim;
   


    private void Start()
    {
        anim = GetComponent<Animator>();
        
    }

    IEnumerator MoveCoroutine()
    {
        

        while (Input.GetAxisRaw("Horizontal") != 0 || Input.GetAxisRaw("Vertical") != 0)
        {
            if (Input.GetKey(KeyCode.LeftShift) || Input.GetKey(KeyCode.RightShift))
            {
                applyRunSpeed = runSpeed;
            }
            else
            {
                applyRunSpeed = 0;
            }

            vector.Set(Input.GetAxisRaw("Horizontal"),
                Input.GetAxisRaw("Vertical"), transform.position.z);


            anim.SetFloat("DirX", vector.x);
            anim.SetFloat("DirY", vector.y);
            anim.SetBool("Idle", false);

            if (vector.x != 0 || vector.y != 0)
            {
                transform.Translate(vector.x * (speed + applyRunSpeed) * Time.deltaTime,
                    vector.y * (speed + applyRunSpeed) * Time.deltaTime, 0);
            }
            yield return null;
        }
        anim.SetBool("Idle", true);
        

    }
    private void Update()
    {
        if (Input.GetAxisRaw("Horizontal") != 0 || Input.GetAxisRaw("Vertical") != 0)
        {
            StartCoroutine(MoveCoroutine());
        }
    }
}

I’ve heard from chat GPT that this code does a lot of running unnecessarily because of the Corutine, and I’ve heard back that there’s no code that actually moves the Sprite.
But it worked well until I wrote the code related to animation (SetFloat, SetBool), so I suspect there’s been a problem in the animation-related part.

Or it seems that the computer couldn’t handle it because the amount of computation was high in the corutine-related part.
I am not satisfied with any of them.
