本章节给骷髅战士加上了音频，并且限制了产生音效的范围
可爱的骷髅战士
AudioManager.cs
关键字段
-
AudioManager instance
实现单例模式，确保全局只有一个AudioManager实例。 -
[SerializeField] private AudioSource[] sfx
存储音效的AudioSource数组，每个元素对应一个音效。 -
[SerializeField] private AudioSource[] bgm
存储背景音乐的AudioSource数组，每个元素对应一首背景音乐。 -
public bool playBgm
控制背景音乐是否播放的开关。 -
private int bgmIndex
当前播放的背景音乐索引。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class AudioManager : MonoBehaviour

PlayerAnimationTriggers.cs
攻击触发的音效

SkeletonIdleState.cs
怪物的音效

using System.Collections.Generic;
