Unity自定义PlayerCombat战斗脚本设置startTimeBtwAttack大于0时失效求助

问题根因 #

你的攻击冷却计时逻辑和输入检测、攻击状态更新的代码块层级完全错误，核心错误有两个：

• 你把timeBtwAttack的重置操作timeBtwAttack = startTimeBtwAttack写在了冷却归零的判断块最开头，等于冷却刚归零就直接被重新赋值成冷却时长，输入检测和攻击状态更新的代码只在冷却归零的单帧能执行，Input.GetKeyDown只有刚好和冷却归零帧完全重合才会触发，几乎不可能触发成功
• 冷却计时的递减逻辑timeBtwAttack -= Time.deltaTime被放在了if(hasSword == true)的块外面，只有当你没有剑的时候才会走冷却递减，有剑的时候冷却值永远不会正常往下掉

修复后代码 #

把冷却重置逻辑移到攻击触发之后，冷却递减逻辑移到hasSword判断块内部，调整后的完整代码如下：

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

public class PlayerCombat : MonoBehaviour
{
    private PlayerMovement speed;

    public bool hasSword = true;

    private float timeBtwAttack;
    public float startTimeBtwAttack;
    public Animator animator;
    public Transform attackPos;
    public float attackRange;
    public LayerMask whatIsEnemies;
    public int damage;

    public AudioSource swordSrc;
    public AudioClip swordClip;

    public float startDazedTime;
    private float dazedTime;

    private float attackTime = .25f;
    private float attackCounter = .25f;

    private bool isAttacking;


    void Start()
    {
        speed = FindObjectOfType<PlayerMovement>();
        // 初始化冷却值，避免开局第一帧就可以攻击，不需要可以删除
        timeBtwAttack = startTimeBtwAttack;
    }

    void Update()
    {
        if (hasSword == true)
        {
            // 处理眩晕逻辑
            if (dazedTime <= 0)
            {
                speed.MovementSpeed = 5f;
            }
            else 
            {
                speed.MovementSpeed = 0f;
                dazedTime -= Time.deltaTime;
            }

            // 攻击状态更新不受冷却影响，单独提取到冷却判断外
            if(isAttacking)
            {
                attackCounter -= Time.deltaTime;
                if (attackCounter <= 0)
                {
                    animator.SetBool("isAttacking", false);
                    isAttacking = false;
                }
            }

            // 统一处理冷却计时
            if (timeBtwAttack > 0)
            {
                timeBtwAttack -= Time.deltaTime;
            }
            else
            {
                // 冷却归零后检测攻击输入
                if (Input.GetKeyDown(KeyCode.X))
                {
                    dazedTime = startDazedTime;
                    attackCounter = attackTime;
                    animator.SetBool("isAttacking", true);

                    swordSrc.PlayOneShot(swordClip);
                    
                    isAttacking = true;

                    Collider2D[] enemiesToDamage = Physics2D.OverlapCircleAll(attackPos.position, attackRange, whatIsEnemies);
                    for (int i = 0; i < enemiesToDamage.Length; i++)
                    {
                        enemiesToDamage[i].GetComponent<EnemyScript>().TakeDamage(damage);
                    }

                    // 攻击触发后再重置冷却
                    timeBtwAttack = startTimeBtwAttack;
                }
            }
        }
    }

    void OnDrawGizmosSelected()
    {
        Gizmos.color = Color.red;
        Gizmos.DrawWireSphere(attackPos.position, attackRange);
    }
}
