unity 加载视频代码怎么写

以下是Unity加载视频的代码示例：

using UnityEngine;
using UnityEngine.Video;

public class VideoPlayerController : MonoBehaviour {
    public VideoPlayer videoPlayer;

    private void Start () {
        videoPlayer = gameObject.AddComponent<VideoPlayer> ();
        videoPlayer.playOnAwake = false;
        videoPlayer.renderMode = VideoRenderMode.RenderTexture;
        videoPlayer.targetTexture = new RenderTexture (Screen.width, Screen.height, 24);
        videoPlayer.isLooping = true;

        string videoURL = "Your Video URL";
        videoPlayer.url = videoURL;
    }

    public void Play () {
        videoPlayer.Play ();
    }

    public void Pause () {
        videoPlayer.Pause ();
    }

    public void Stop () {
        videoPlayer.Stop ();
    }
}

其中，videoPlayer对象是用来控制视频播放的组件，需要添加到场景的游戏物体上，videoURL是你要加载的视频资源的路径。使用Play、Pause、Stop方法可以控制视频的播放。
