使用 flipX 时 Sprite 渲染器出现意外行为

Question

sprite.flipX 没有按预期工作，日志显示它更新了 flipx 值，但它对我的播放器检查器上的统一 SpriteRenderer 没有影响。 玩家移动、跳跃、向两侧跳跃，所有动画都正常工作，除了右行走动画的改变方向。 在网上和统一论坛上搜索了一天，非常沮丧，请帮我解决问题。

我的代码：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
 
public class PlayerMovement : MonoBehaviour
{
    private Rigidbody2D rb;
    private BoxCollider2D coll; //top platform collision -> line 26
    private SpriteRenderer sprite;
    private Animator anim;
 
    [SerializeField] private LayerMask jumpableGround; // for our new box colider, terrain layer pass
 
    private float dirX = 0f;
    [SerializeField] private float moveSpeed = 7f;
    [SerializeField] private float jumpForce = 14f;
 
    private enum MovementState { idle, walk, jumping, falling, side_jump_left, side_jump_right }
 
    [SerializeField] private AudioSource jumpSoundEffect;
 
    // Start is called before the first frame update
    private void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        coll = GetComponent<BoxCollider2D>();
        sprite = GetComponent<SpriteRenderer>();
        anim = GetComponent<Animator>();
    }
 
    // Update is called once per frame
    private void Update()
    {
        dirX = Input.GetAxisRaw("Horizontal");
        rb.velocity = new Vector2(dirX * moveSpeed, rb.velocity.y);
 
        if (Input.GetButtonDown("Jump") && IsGrounded())
        {
            //jumpSoundEffect.Play();
            rb.velocity = new Vector2(rb.velocity.x, jumpForce);
        }
 
        UpdateAnimationState();
    }
 
    private void UpdateAnimationState()
    {
        MovementState state;

        if (dirX < 0f)
        {
            state = MovementState.walk;
            sprite.flipX = false ;
        }

        else if (dirX > 0f)
        {
            state = MovementState.walk;
            sprite.flipX = true ;
        }
        
        else
        {
            state = MovementState.idle;
        }
 
        if (rb.velocity.y > .1f)
        {
            state = MovementState.jumping;
        }
        else if (rb.velocity.y < -.1f)
        {
            state = MovementState.falling;
        }
        if (dirX>0f && Input.GetButtonDown("Jump") && IsGrounded())
        {
            //jumpSoundEffect.Play();
            state = MovementState.side_jump_right;
           
        }
        else if (dirX<0f && Input.GetButtonDown("Jump") && IsGrounded())
        {
            //jumpSoundEffect.Play();
            state = MovementState.side_jump_left;
        }
           
 
        anim.SetInteger("state", (int)state);
    }
 
    private bool IsGrounded()
    {
        return Physics2D.BoxCast(coll.bounds.center, coll.bounds.size, 0f, Vector2.down, .1f, jumpableGround); // new box colider for our player (position,size,rotation,vector, offset from our original box)
    }
}

如果我取消选中行走动画检查器中的写入默认值标记，则在播放右侧跳跃动画后问题会翻转，角色行走动画仅向右移动。

在这两种情况下，玩家的身体都在 x 轴上移动，因此输入正确传递。
