视频播放器 (Video Player) 组件

使用视频播放器组件可将视频文件附加到游戏对象，然后在运行时在游戏对象的纹理上播放。

以下截屏显示了一个连接到球形游戏对象的视频播放器组件。

By default, the Material Property of a Video Player component is set to a GameObject’s main texture, which means that when the Video Player component is attached to a GameObject that has a Renderer, it automatically assigns itself to the Texture on that Renderer (because this is the main Texture for the GameObject). Here, the GameObject has a Mesh Renderer component, so the Video Player automatically assigns it to the Renderer field, which means the Video Clip plays on the Mesh Renderer’s Texture.

还可设置要播放视频的特定目标，包括：

• 摄像机平面

• 渲染纹理

• 材质纹理参数

• 组件中的任何纹理字段

视频播放器脚本示例

The following script demonstrates a few of the Video Player component’s features.

// Examples of Video Player function

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Will attach a Video Player to the main camera.
        GameObject camera = GameObject.Find("Main Camera");

        // VideoPlayer automatically targets the camera backplane when it is added
        // to a camera object, no need to change videoPlayer.targetCamera.
        var videoPlayer = camera.AddComponent<UnityEngine.Video.VideoPlayer>();

        // Play on awake defaults to true. Set it to false to avoid the url set
        // below to auto-start playback since we're in Start().
        videoPlayer.playOnAwake = false;

        // By default, Video Players added to a camera will use the far plane.
        // Let's target the near plane instead.
        videoPlayer.renderMode = UnityEngine.Video.VideoRenderMode.CameraNearPlane;

        // This will cause our Scene to be visible through the video being played.
        videoPlayer.targetCameraAlpha = 0.5F;

        // Set the video to play. URL supports local absolute or relative paths.
        // Here, using absolute.
        videoPlayer.url = "/Users/graham/movie.mov";

        // Skip the first 100 frames.
        videoPlayer.frame = 100;

        // Restart from beginning when done.
        videoPlayer.isLooping = true;

        // Each time we reach the end, we slow down the playback by a factor of 10.
        videoPlayer.loopPointReached += EndReached;

        // Start playback. This means the Video Player may have to prepare (reserve
        // resources, pre-load a few frames, etc.). To better control the delays
        // associated with this preparation one can use videoPlayer.Prepare() along with
        // its prepareCompleted event.
        videoPlayer.Play();
    }

    void EndReached(UnityEngine.Video.VideoPlayer vp)
    {
        vp.playbackSpeed = vp.playbackSpeed / 10.0F;
    }
}
