Unity3D動態加載外部MovieTexture視頻

 

 

網上大家也寫了很多Unity3D中播放視頻的教程，關於播放外部視頻的還是比較少，所以寫這篇文章，不足之處，還望讀者指正。

 

在Unity3D中，我們一般使用播放視頻的方法：將*.mov,*.mp4等格式拖拽到Asset中目錄，Unity3D會轉換為MovieTexture，音頻AudioClip在子節點可找到。但，如果我們想動態加載外部視頻，該怎么做呢？以下附上實現腳本，可自行修改。

 

using UnityEngine;
using System.Collections;
using System.IO;

//[RequireComponent(typeof(AudioSource))]
public class MoviePlayer : MonoBehaviour
{

   private  MovieTexturemovieTexture;//
   private string movieDir = "/Data/Movie";//根目錄下

   private float movietime;
    privatestatic MoviePlayer instance;
   public static MoviePlayer Instance
    {
       get
       {
           return instance;
       }
    }
   void Start()
    {
      StartCoroutine(DownloadMovie());

       Play();

       instance = this;
    }


   public void Play()
    {
       audio.Play();
       movieTexture.Play();


       Debug.Log("Play");
    }

   public void Pause()
    {
       audio.Pause();
       movieTexture.Pause();
       Debug.Log("Pause");

    }

   public void Stop()
    {
       audio.Stop();
       movieTexture.Stop();
       Debug.Log("Stop");
    }

   public bool IsPlaying()
    {
       return audio.isPlaying;
    }

   public float GetMovieTime()
    {
       return audio.time;
    }

   IEnumerator DownloadMovie()
   {//WWW www = new WWW("file:///D://Project//Movie/Data/Movie//movie.ogv");

       string[] files = Directory.GetFiles(Directory.GetCurrentDirectory() +movieDir);//PC版,其他版本只需要修改視頻文件讀取方式
       WWW www = new WWW("file:///" + files[0]);
       movieTexture = (MovieTexture)www.movie;

       while(!movieTexture.isReadyToPlay)
            yield return www;


       renderer.material.mainTexture = movieTexture;//視頻紋理
       audio.clip = movieTexture.audioClip;//音頻


       Play();
    }
}
