Unity中敌人攻击玩家无法触发takeDamage造成伤害问题求助

我编写了一个脚本用于检测玩家是否在附近，触发敌人攻击动画并对玩家造成伤害，但目前遇到伤害无法生效的问题：已在攻击命中帧设置动画事件，调用玩家脚本中的takeDamage方法减少生命值，但玩家生命值无任何变化。

敌人AI脚本代码 #

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

public class EnemyAI : MonoBehaviour
{
    [SerializeField] private float attackCooldown;
    [SerializeField] private int damage;
    private float cooldownTimer = Mathf.Infinity;
    [SerializeField] private BoxCollider2D boxCollider;
    [SerializeField] private LayerMask playerLayer;
    [SerializeField] private float range;
    [SerializeField] private float ColliderDistance;
    private Animator anim;
    public PlayerHealth playerHealth;

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


    private void Update()
    {
        cooldownTimer += Time.deltaTime;

        if (playerInSight())
        {
            if (cooldownTimer >= attackCooldown)
            {
                cooldownTimer = 0;
                anim.SetTrigger("meleeAttack");

            }
        }
    }

    private bool playerInSight()
    {
        RaycastHit2D hit = 
        Physics2D.BoxCast(boxCollider.bounds.center + transform.right * range * transform.localScale.x * ColliderDistance,
        new Vector3(boxCollider.bounds.size.x * range, boxCollider.bounds.size.y, boxCollider.bounds.size.z)
        , 0, Vector2.left, 0, playerLayer);

        return hit.collider != null;
    }

    private void OnDrawGizmos()
    {
        Gizmos.color = Color.red;
        Gizmos.DrawWireCube(boxCollider.bounds.center + transform.right * range * transform.localScale.x * ColliderDistance,
         new Vector3(boxCollider.bounds.size.x * range, boxCollider.bounds.size.y, boxCollider.bounds.size.z));
    }

    private void damagePlayer()
    {
        if (playerInSight())
        {
            playerHealth.takeDamage(damage);
        }
    }
}

玩家受伤害方法代码 #

public void takeDamage(int damage)
{
    currentHealth -= damage;

    if (currentHealth < maxHealth && !_isPlayingAnimation)
    {
        maxHealth = currentHealth;
        anim.SetTrigger("attacked");
        _isPlayingAnimation = true;
    }

    if (currentHealth <= 0)
    {
        Debug.Log("Player has died!");
        anim.SetBool("isDead", true);
        _isPlayingAnimation = true;
    }
}

排查方向 #

• 检查PlayerHealth引用：EnemyAI中的playerHealth字段需在Unity编辑器中手动拖入挂载了PlayerHealth组件的玩家对象，未赋值会导致空引用，无法调用takeDamage。可在damagePlayer中添加Debug.Log(playerHealth)验证是否为空。
• 验证动画事件绑定：确认攻击动画的命中帧上，动画事件的函数名是damagePlayer（大小写一致、无拼写错误），且绑定的对象是敌人的EnemyAI组件。
• 攻击帧时玩家是否在检测范围内：动画播放过程中敌人位置可能偏移，导致damagePlayer内的playerInSight()返回false。可暂时注释掉该if判断，直接调用playerHealth.takeDamage(damage)测试是否生效。
• 修正玩家脚本逻辑错误：玩家takeDamage中maxHealth = currentHealth是错误逻辑——maxHealth应代表玩家最大生命值，不应随当前生命值降低而修改，这会导致后续生命值判断异常，甚至视觉上看起来没掉血。需删除该行代码。
• 检查LayerMask设置：确认EnemyAI的playerLayer已正确选择玩家所在的Layer，否则playerInSight会一直返回false，无法触发攻击和伤害逻辑。
