Unity 视频控制暂停播放以及滑动条拖拽(笔记)

• 3d物体播放视频
• UI播放视频

1. 创建一个cube,在cube下创建canvas,然后调到世界,并调整位置和大小,

2. cube上添加audio source组件和video player组件

3. 在创建两个image,image下面创建text文本,分别为暂停和播放,然后再image上添加button组件
   

4. 创建脚本,写代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Video;
using UnityEngine.UI;

public class AudioPlayer : MonoBehaviour {
    VideoPlayer videoPlayer;
    Slider slider;
	// Use this for initialization
	void Start () {
        videoPlayer = GetComponent();
        slider = transform.GetChild(0).GetChild(0).GetComponent();
        slider.maxValue=(float)videoPlayer.clip.length;//视频长度
	}
	public void Play()
    {
        videoPlayer.Play();
    }
    public void Pause()
    {
        videoPlayer.Pause();
    }
    public void ChangeFloat(float t)
    {
        if (SliderPointer.isClick)
        {
            videoPlayer.time = slider.value;
        }
        
    }
    // Update is called once per frame
    void Update () {
        if (!SliderPointer.isClick)
        {
            slider.value = (float)videoPlayer.time;
        }
        
    }
}

5. 再创建一个脚本挂在slider上,

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;

public class SliderPointer : MonoBehaviour,IPointerDownHandler,IPointerUpHandler {
    public static bool isClick = false;
    public void OnPointerDown(PointerEventData eventData)
    {
        isClick = true;
    }

    public void OnPointerUp(PointerEventData eventData)
    {
        isClick = false;
    }

    // Use this for initialization
    void Start () {
		
	}
	
	// Update is called once per frame
	void Update () {
		
	}
}

6. 写好后,把全景视频拖拽,button事件拖拽还有slider上面的拖拽
7. 效果

3d物体播放视频

1. 创建rawimage,添加audio source组件和video player组件,然后把视频拖进去

rawimage和image的区别
image贴图类型只能是精灵图片
rawimage什么贴图都可以

2. 要想承接播放一个视频,就要在assets创建一个Render Texture,然后拖拽到rawimage属性面板里的Texture里.
   
3. 把刚创建的Render Texture也要拖拽到video player组件属性面板里的相应位置
   
   运行后就看到视频了,但是会发现视频并没有铺满image,就要去写脚本
4. 把脚本挂在canvas上

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Video;

public class RawImageOaly : MonoBehaviour {
    public RawImage rawImage;
    private VideoPlayer videoPlayer;
	// Use this for initialization
	void Start () {
        videoPlayer = rawImage.GetComponent();
        rawImage.texture = videoPlayer.texture;
	}
	public void Play()
    {
        videoPlayer.Play();
    }
    public void Pause()
    {
        videoPlayer.Pause();
    }
    
    // Update is called once per frame
    void Update () {
        rawImage.texture = videoPlayer.texture;
    }
}

5.写好代码后回到unity拖拽后运行,就正常播放了,然后添加两个按钮,控制视频的暂停和播放,和上面的一样就不再细述了
