Unity中角色向左翻转动画失效问题排查求助

我在Unity开发中，通过动画录制功能制作了角色向左移动、中途停止的动画，并将这些动画整合为混合树用于左右转向逻辑。但实际运行时，角色向左移动的翻转画面无法正常显示。

我已经在LateUpdate方法中设置了Animator的DirX、DirY和Idle参数，混合树的动画参数匹配规则为：向左对应DirX=-1，向右对应DirX=1。在Animator预览窗口中，Sprite可以正常翻转，但进入游戏运行后效果不符合预期。

以下是完整的PlayerManager代码：

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

public class PlayerManager : MonoBehaviour
{
    Coroutine playerMoveRoutine;

    public float speed = 500f;
    public float runSpeed = 200f;

    public GameObject player;
    public GameObject rightArrow;
    public GameObject leftArrow;
    public GameObject[] backgrounds;
    public GameObject[] Borders;

    private Vector2 movement; //Use the direction key to move
    private bool isRunning;
    private Animator anim;
    private Rigidbody2D rb;

    private void Start()
    {
        anim = player.GetComponent<Animator>();
        rb = player.GetComponent<Rigidbody2D>();
    }

    
    private void Update()
    {
        // Get input
        movement.x = Input.GetAxisRaw("Horizontal");
        movement.y = Input.GetAxisRaw("Vertical");
        isRunning = Input.GetKey(KeyCode.LeftShift) || Input.GetKey(KeyCode.RightShift);

        
        if (Input.GetMouseButtonDown(0)) // Left mouse click detection
        {
            Vector2 worldPoint = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            RaycastHit2D hit = Physics2D.Raycast(worldPoint, Vector2.zero);

            if (hit.collider != null)
            {
                
                if (hit.collider.gameObject == rightArrow)
                {
                    int clickX = 1;
                    // If we're already moving, cancel that coroutine so the two don't execute at the same time
                    if (playerMoveRoutine != null)
                    {
                        StopCoroutine(playerMoveRoutine);
                    }
                    playerMoveRoutine = StartCoroutine(ArrowClick(clickX));

                }
                else if (hit.collider.gameObject == leftArrow)
                {
                    int clickX = -1;
                    // If we're already moving, cancel that coroutine so the two don't execute at the same time
                    if (playerMoveRoutine != null)
                    {
                        StopCoroutine(playerMoveRoutine);
                    }
                    playerMoveRoutine = StartCoroutine(ArrowClick(clickX));
                }
            }
        }
    }

    public IEnumerator ArrowClick(int _clickX)
    {
        float speed = 200;
        Vector2 target = new Vector2(500 * _clickX, 0);
        while (Vector2.Distance(player.transform.position, target) > 0.05f)
        {
            // Changed from hardcoded "10" to rather be based on the "Time.deltaTime": enables framerate independence (player will move the same amount in a second, regardless of FPS)
            player.transform.position = Vector2.MoveTowards(player.transform.position, target, speed * Time.deltaTime);

            // Tells the game to wait a frame before continuing execution
            yield return null;
        }
    }


    private void FixedUpdate()
    {
        // Move the character
        float currentSpeed = isRunning ? speed * runSpeed : speed;
        Vector2 velocity = movement.normalized * currentSpeed;
        rb.MovePosition(rb.position + velocity * Time.fixedDeltaTime);
    }

    private void LateUpdate()
    {
        // Update animator
        anim.SetFloat("DirX", movement.x);
        anim.SetFloat("DirY", movement.y);
        anim.SetBool("Idle", movement.magnitude == 0);
    }
}
