此处为加载mp3,需要加载其他格式可以修改AudioType
private IEnumerator LoadFile2AudioClip_IE(string uri)//加载本地资源为声音
{
UnityWebRequest request = UnityWebRequestMultimedia.GetAudioClip(uri,AudioType.MPEG);
yield return request.SendWebRequest();
AudioClip clip = DownloadHandlerAudioClip.GetContent(request);
audioSource.clip = clip;
audioSource.Play();
}
