        }
        else
        {

        }
    }

3. 弹夹类（GunMagazine）

using UnityEngine;

public class GunMagazine : MonoBehaviour

        ammoCount = maxAmmo;
        Debug.Log("Reloaded!");
    }

    // 发射一发子弹的方法
    public bool FireBullet()
    {
        if (ammoCount > 0)
        {
            ammoCount--;
            return true;
        }
        else
        {

        }
    }
}

4. 枪类（Weapon）

using UnityEngine;

public class Weapon : MonoBehaviour
{
    public GunBody gunBody;
    public GunMuzzle gunMuzzle;
    public GunMagazine gunMagazine;

    void Start()
    {
        // 初始化各组件
        if (gunBody == null || gunMuzzle == null || gunMagazine == null)
        {
            Debug.LogError("Weapon components are not assigned!");
        }
    }

    // 开火的方法
    public void Fire()
    {
        if (gunMagazine.FireBullet())
        {
            gunMuzzle.PlayFireSound();
            Debug.Log($"{gunBody.gunName} fired!");
        }
    }
}

5. 武器控制类（WeaponCon）

using UnityEngine;

public class WeaponCon : MonoBehaviour
{
    public Weapon weapon;
