本章节添加了更多的音效细节

音频管理器

AudioManager.cs

使得多个音效可以同时播放，注释掉以下代码

 public void PlaySFX(int _sfxIndex,Transform _source)//播放音效
 {
     //if(sfx[_sfxIndex].isPlaying)//如果音效正在播放
     //    return;

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

public class AudioManager : MonoBehaviour
{
    public static AudioManager instance;

    [SerializeField] private float sfxMinimumDistance;//音效最小距离
    [SerializeField] private AudioSource[] sfx;//音效
    [SerializeField] private AudioSource[] bgm;//背景音乐


    public bool playBgm;
    private int bgmIndex;


    private void Awake()
    {
        if(instance != null)
            Destroy(instance.gameObject);
        else
            instance = this;
    }


    private void Update()
    {
        if (!playBgm)
            StopAllBGM();
        else
        {
            if(!bgm[bgmIndex].isPlaying)//如果背景音乐没有播放
                PlayBGM(bgmIndex);
        }
    }


    public void PlaySFX(int _sfxIndex,Transform _source)//播放音效
    {
        //if(sfx[_sfxIndex].isPlaying)//如果音效正在播放
        //    return;


        if(_source!=null && Vector2.Distance(PlayerManager.instance.player.transform.position, _source.position) > sfxMinimumDistance)//距离过远不播放
            return;



        if (_sfxIndex < sfx.Length)
        {
            sfx[_sfxIndex].pitch = Random.Range(.85f, 1.15f);//设置音效的音调
            sfx[_sfxIndex].Play();
        }
    }

    public void StopSFX(int _index) => sfx[_index].Stop();//停止音效


    public void PlayRandomBGM()//播放随机背景音乐
    {
        bgmIndex = Random.Range(0, bgm.Length);
        PlayBGM(bgmIndex);
    }



    public void PlayBGM(int _bgmIndex)//播放背景音乐
    {
        bgmIndex = _bgmIndex;

        StopAllBGM();
        bgm[bgmIndex].Play();
    }


    public void StopAllBGM()
    {
        for (int i = 0; i < bgm.Length; i++)
        {
            bgm[i].Stop();
        }
    }

    
}

Blackhole_Skill.cs

加上了释放技能的玩家语音和技能音效

        AudioManager.instance.PlaySFX(3, player.transform);
        AudioManager.instance.PlaySFX(6, player.transform);

using UnityEngine;
using UnityEngine.UI;

public class Blackhole_Skill : Skill
{

    [SerializeField] private UI_SkillTreeSlot blackHoleUnlockButton;
    public bool blackHoleUnlocked { get; private set; }
    [SerializeField] private int amountOfAttacks;
    [SerializeField] private float cloneCooldown;
    [SerializeField] private float blackholeDuration;
    [Space]
    [SerializeField] private GameObject blackHolePrefab;
    [SerializeField] private float maxSize;
    [SerializeField] private float growSpeed;
    [SerializeField] private float shrinkSpeed;

    BlackHole_Skill_Controller currentBlackhole;//当前的黑洞

  


    private void UnlockBlackHole()
    {
        if (blackHoleUnlockButton.unlocked)
            blackHoleUnlocked =true;
    }

    public override bool CanUseSkill()
    {
        return base.CanUseSkill();
    }


    public override void UseSkill()
    {
        base.UseSkill();//调用了基类 Skill中的 UseSkill 方法

        GameObject newBlackHole = Instantiate(blackHolePrefab, player.transform.position, Quaternion.identity); //这行代码使用 Instantiate 方法在玩家当前位置生成一个新的黑洞对象

        currentBlackhole = newBlackHole.GetComponent<BlackHole_Skill_Controller>();

        currentBlackhole.SetupBlackhole(maxSize, growSpeed, shrinkSpeed, amountOfAttacks, cloneCooldown,blackholeDuration);//调用SetupBlackhole，传递一系列参数来配置黑洞的行为，包括最大尺寸、增长速度、缩小速度、攻击次数和克隆冷却时间

        AudioManager.instance.PlaySFX(3, player.transform);
        AudioManager.instance.PlaySFX(6, player.transform);

    }

    protected override void Start()
    {
        base.Start();

        blackHoleUnlockButton.GetComponent<Button>().onClick.AddListener(UnlockBlackHole);
    }

    protected override void Update()
    {
        base.Update();
    }

    public bool SkillCompeleted()
    {
        if(!currentBlackhole)
        {
            return false;
        }

        if (currentBlackhole.playerCanExitState)
        {
            currentBlackhole = null;
            return true;
        }

        return false;
    }

    public float GetBlackholeRadius()//解决水晶黑洞的攻击范围问题
    {
        return maxSize / 2;
    }

    protected override void CheckUnlock()
    {
        base.CheckUnlock();

        UnlockBlackHole();  
    }
}

ItemObject.cs

添加了拾取物品的音效

public void PickupItem()//将物品添加到背包，然后销毁
{
    //11月12日改
    if (!Inventory.instance.CanAddItem() && itemData.itemType == ItemType.Equipment)//如果不能添加物品并且物品类型是装备
    {
        rb.velocity = new Vector2(0, 7);
        return;
    }


    AudioManager.instance.PlaySFX(18, transform);
    Inventory.instance.AddItem(itemData);
    Destroy(gameObject);
}

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

//创建一个物体，放入这个脚本
public class ItemObject : MonoBehaviour
{

    [SerializeField] private Rigidbody2D rb;
    [SerializeField] private ItemData itemData;//就是你放入的图标

    private void SetupVisuals()//设置物品的图标和名称
    {
        if (itemData == null)
            return;


        SpriteRenderer spriteRenderer = GetComponent<SpriteRenderer>();
        if (spriteRenderer == null)
        {
            Debug.LogError("SpriteRenderer component is missing");
            return;
        }
        GetComponent<SpriteRenderer>().sprite = itemData.icon;//在编辑器中显示图标
        gameObject.name = "Item object - " + itemData.itemName;//直接在编辑器中显示名字
    }


    public void SetupItem(ItemData _itemData,Vector2 _velocity)//配置物品的数据和掉落的初始速度
    {
        itemData = _itemData;
        rb.velocity = _velocity;

        SetupVisuals();
    }


    public void PickupItem()//将物品添加到背包，然后销毁
    {
        //11月12日改
        if (!Inventory.instance.CanAddItem() && itemData.itemType == ItemType.Equipment)//如果不能添加物品并且物品类型是装备
        {
            rb.velocity = new Vector2(0, 7);
            return;
        }


        AudioManager.instance.PlaySFX(18, transform);
        Inventory.instance.AddItem(itemData);
        Destroy(gameObject);
    }
}

Checkpoint.cs

到检查点如果火堆未启动过，加个点亮火堆的音效

        if(activationStatus==false)
            AudioManager.instance.PlaySFX(5, transform);

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


//2024.11.28 19：38 疑似有点生病
//
public class Checkpoint : MonoBehaviour
{
    private Animator anim;
    public string id;
    public bool activationStatus;


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


    [ContextMenu("产生检查点ID")]//在编辑器中生成一个按钮
    private void GenerateId()
    {
        id = System.Guid.NewGuid().ToString();
    }


    private void OnTriggerEnter2D(Collider2D collision)//检测到碰撞
    {
        if (collision.GetComponent<Player>()!=null)//检测到玩家
        {
            ActivateCheckPoint();//激活检查点
        }
    }

    public void ActivateCheckPoint()//激活检查点
    {
        if(activationStatus==false)
            AudioManager.instance.PlaySFX(5, transform);


        activationStatus = true;
        anim.SetBool("active", true);
    }
}

PlayerMoveState.cs

移动会产生脚步声

    public override void Enter()
    {
        base.Enter();

        AudioManager.instance.PlaySFX(14,null);
    }

    public override void Exit()
    {
        base.Exit();

        AudioManager.instance.StopSFX(14);
    }

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

public class PlayerMoveState : PlayerGroundedState
{
    public PlayerMoveState(Player _player, PlayerStateMachine _stateMachine, string _animBoolName) : base(_player, _stateMachine, _animBoolName)
    {
    }

    public override void Enter()
    {
        base.Enter();

        AudioManager.instance.PlaySFX(14,null);
    }

    public override void Exit()
    {
        base.Exit();

        AudioManager.instance.StopSFX(14);
    }

    public override void Update()
    {
        base.Update();


        player.SetVelocity(xInput * player.moveSpeed, rb.velocity.y);

        if (xInput == 0  || player.IsWallDetected())
            stateMachine.ChangeState(player.idleState);//如果玩家没有按下左箭头键或右箭头键，我们将切换到Idle状态
    }
}
