我正在尝试使用在运行时加载 mp3 文件WWW http://docs.unity3d.com/ScriptReference/WWW.htmlUnity中提供的类。
我没有收到任何错误,但在处理歌曲后我无法播放音乐。我到处都找过了,但找不到任何可以帮助我的东西。
这是我当前使用的代码:
public class OpenFile : MonoBehaviour {
string path;
string extension;
public GameObject musicAnalysis;
string songName;
float length;
AudioSource song;
// Use this for initialization
void Start () {
song = musicAnalysis.GetComponent<AudioSource>();
}
// Update is called once per frame
void Update () {
if(song.isPlaying != true){
song.Play();
}
}
public void FileSelect(){
//Open windows Exploer
path = EditorUtility.OpenFilePanel("Select a Song","","");
print(path);
//Take the end of the the path and sasve it to another string
extension = path.Substring(path.IndexOf('.') + 1);
print (extension);
//Check if the user has select the correct file
if(extension == "mp3" || extension == "wav" || extension == "ogg"){
//if correct file process file
print ("You have selected the correct file type congrats");
LoadSong();
print ("Song Name: " + songName);
print ("Song Length: " + length);
}
//if the user selects the wrong file type
else{
//pop up box that tells the user that they have selected the wrong file
EditorUtility.DisplayDialog("Error","Incorrect File Type Please select another","Ok");
////Open windows Exploer
path = EditorUtility.OpenFilePanel("Select a Song","","");
}
}
void LoadSong(){
WWW www = new WWW("file://" + path);
song.clip = www.audioClip;
songName = www.audioClip.name;
length = www.audioClip.length;
while(!www.isDone){
print ("Processing File" + path);
}
if(www.isDone == true){
print ("Song has been processed");
}
}
}
如上所述,Windows 不支持 MP3,因此请使用 OGG 或 WAV。
编辑:此方法实际上适用于 mp3,我在 Unity 2019.3.6f 上使用多个文件进行了测试
您必须等待 WWW 完成才能访问该剪辑。并且 WWW 必须在异步协程中加载。
public void LoadSong()
{
StartCoroutine(LoadSongCoroutine());
}
IEnumerator LoadSongCoroutine()
{
string url = string.Format("file://{0}", path);
WWW www = new WWW(url);
yield return www;
song.clip = www.GetAudioClip(false, false);
songName = song.clip.name;
length = song.clip.length;
}
