标题: AR metaioMovieTexture 用WWW机制下载视频播放

metaio 自带的movietexture中播放视频需要一个本地路径，就是本地必须要有视频，
这个用来下载就没什么用了（本地都有还下载干啥），在这里谢谢luc 的解答，就是下载完成之后
在添加metaiomovietexture 这样问题就完美的解决了@Luck  3ｑ．．．
public GameObject MoviePlan;

//下载地址
private string DownLoadMovieUrl = "[url=]http://alianhome.com/LHT/videoGood.3g2[/url]";
//加载本地的地址
private string LoadMovieUrl;
void Start()
{
      if (MoviePlan.GetComponent<metaioMovieTexture>()!= null)
      {
         Destroy(MoviePlan.GetComponent<metaioMovieTexture>());
      }
      LoadMovieUrl = Application.persistentDataPath + "/videoGood.3g2";
}
protected override void onTrackingEvent(System.Collections.Generic.List<TrackingValues> trackingValues)
{
      foreach (TrackingValues item in trackingValues)
      {
         if (item.state == TrackingState.Found)
         {
            TrackFound();
            MoviePlan.GetComponent<metaioMovieTexture>().play(true);
         }
         if (item.state == TrackingState.Lost)
         {

         }
      }
}
void TrackFound()
{
      //本地是否有下载文件
      if (!File.Exists(LoadMovieUrl))
      {
         StartCoroutine(DownLoadMovie());
      }
      else
      {
         StartCoroutine(LoadMovie());
      }
}
//加载本地视频
IEnumerator LoadMovie()
{
      WWW _loadMovie = new WWW(LoadMovieUrl);
      yield return _loadMovie;
      MoviePlan.AddComponent<metaioMovieTexture>();
      MoviePlan.GetComponent<metaioMovieTexture>().movieFile = LoadMovieUrl;
      MoviePlan.GetComponent<metaioMovieTexture>().play(true);
}
//下载视频
IEnumerator DownLoadMovie()
{
      WWW _dwonLoadMovie = new WWW(DownLoadMovieUrl);
      yield return _dwonLoadMovie;
      //写入本地
      File.WriteAllBytes(LoadMovieUrl, _dwonLoadMovie.bytes);
      //读取本地视频的路径
      string readMovieFilePath = LoadMovieUrl;
      MoviePlan.AddComponent<metaioMovieTexture>();
      MoviePlan.GetComponent<metaioMovieTexture>().movieFile = readMovieFilePath;
      MoviePlan.GetComponent<metaioMovieTexture>().play(true);
}
