unity webgl怎么通过StreamingAssets的方式点击不同按钮播放mp4格式视频的操作方式和完整代码,按钮和视频10个以上

你可以通过以下步骤实现Unity WebGL通过StreamingAssets方式播放不同的MP4视频并在按钮点击时切换视频：

1. 创建一个空的GameObject，命名为VideoPlayer，为其添加VideoPlayer组件。
2. 在Unity编辑器中创建多个空的GameObject，用于存放不同的按钮，命名为Button1、Button2、Button3等。
3. 为每个按钮GameObject添加Button组件，并设置按钮的位置和大小。
4. 创建一个C#脚本，命名为VideoController，用于管理视频和按钮的行为。在脚本中定义一个VideoClip数组，用于存放所有的视频文件。
5. 在Start()函数中，将所有视频文件加载到VideoClip数组中。例如：

public VideoClip[] videoClips;

void Start()
{
    videoClips = new VideoClip[10];
    videoClips[0] = Resources.Load<VideoClip>("StreamingAssets/video1");
    videoClips[1] = Resources.Load<VideoClip>("StreamingAssets/video2");
    //...
}

6. 在每个按钮的OnClick()函数中，切换当前播放的视频。例如：

public void OnClickButton1()
{
    videoPlayer.clip = videoClips[0];
    videoPlayer.Play();
}

public void OnClickButton2()
{
    videoPlayer.clip = videoClips[1];
    videoPlayer.Play();
}

//...

7. 在VideoController脚本中，为VideoPlayer组件添加一个事件监听，当视频播放完成时自动切换到下一个视频。例如：

void Start()
{
    //...

    videoPlayer.loopPointReached += OnVideoEnd;
}

void OnVideoEnd(VideoPlayer vp)
{
    int index = System.Array.IndexOf(videoClips, vp.clip);
    if (index < videoClips.Length - 1)
    {
        videoPlayer.clip = videoClips[index + 1];
        videoPlayer.Play();
    }
}

完整的代码实现如下：

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Video;

public class VideoController : MonoBehaviour
{
    public VideoPlayer videoPlayer;
    public VideoClip[] videoClips;

    void Start()
    {
        videoClips = new VideoClip[10];
        videoClips[0] = Resources.Load<VideoClip>("StreamingAssets/video1");
        videoClips[1] = Resources.Load<VideoClip>("StreamingAssets/video2");
        videoClips[2] = Resources.Load<VideoClip>("StreamingAssets/video3");
        videoClips[3] = Resources.Load<VideoClip>("StreamingAssets/video4");
        videoClips[4] = Resources.Load<VideoClip>("StreamingAssets/video5");
        videoClips[5] = Resources.Load<VideoClip>("StreamingAssets/video6");
        videoClips[6] = Resources.Load<VideoClip>("StreamingAssets/video7");
        videoClips[7] = Resources.Load<VideoClip>("StreamingAssets/video8");
        videoClips[8] = Resources.Load<VideoClip>("StreamingAssets/video9");
        videoClips[9] = Resources.Load<VideoClip>("StreamingAssets/video10");

        videoPlayer.loopPointReached += OnVideoEnd;
    }

    public void OnClickButton1()
    {
        videoPlayer.clip = videoClips[0];
        videoPlayer.Play();
    }

    public void OnClickButton2()
    {
        videoPlayer.clip = videoClips[1];
        videoPlayer.Play();
    }

    public void OnClickButton3()
    {
        videoPlayer.clip = videoClips[2];
        videoPlayer.Play();
    }

    public void OnClickButton4()
    {
        videoPlayer.clip = videoClips[3];
        videoPlayer.Play();
    }

    public void OnClickButton5()
    {
        videoPlayer.clip = videoClips[4];
        videoPlayer.Play();
    }

    public void OnClickButton6()
    {
        videoPlayer.clip = videoClips[5];
        videoPlayer.Play();
    }

    public void OnClickButton7()
    {
        videoPlayer.clip = videoClips[6];
        videoPlayer.Play();
    }

    public void OnClickButton8()
    {
        videoPlayer.clip = videoClips[7];
        videoPlayer.Play();
    }

    public void OnClickButton9()
    {
        videoPlayer.clip = videoClips[8];
        videoPlayer.Play();
    }

    public void OnClickButton10()
    {
        videoPlayer.clip = videoClips[9];
        videoPlayer.Play();
    }

    void OnVideoEnd(VideoPlayer vp)
    {
        int index = System.Array.IndexOf(videoClips, vp.clip);
        if (index < videoClips.Length - 1)
        {
            videoPlayer.clip = videoClips[index + 1];
            videoPlayer.Play();
        }
    }
}
