unity 角色控制 播放animation unity代码控制动画播放

这个老版本的可以借鉴，新版的已经出来了，

结果如上图。。。

如图所示，里面有开始，暂停，重播，关闭按钮，同时有一个播放视频的进度条，以及后面两个显示时间总长度和实时时间的文本，以及中间播放视频的RawImage。

上一次写了如何设置RawImage进行自动播放，这次就直接用代码控制，同时还有进度条的控制。

在写代码之前，还需要把按钮和组件相对的设置好，以及RawImage的设置调整好

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

public class VideoCrol : MonoBehaviour {

	public static VideoCrol instance;

	private VideoPlayer vPlayer;

	public GameObject videoImage;//播放image
	private Button BtnPlay, BtnPause, BtnReStart;//开始，暂停，重播
	public Slider sliderVideo;//进度条
	private Button BtnX;//关闭
	private Image VideoPanel;//视频背景
	private Text NowTime;//播放时间
	private Text TotalTime;//总时间

	private float tt;//视频总时长
	private float Index_t;//进度条计时时间

	private float hour, min, second;

	private bool IsPlay = true;

	void Awake()
	{
		instance = this;
		vPlayer = videoImage.GetComponent<VideoPlayer>();
		BtnPlay = GameObject.Find("Kaishi").GetComponent<Button>();
		BtnPause = GameObject.Find("Zanting").GetComponent<Button>();
		BtnReStart = GameObject.Find("ReWindButton").GetComponent<Button>();
		sliderVideo = GameObject.Find("SliderVideo").GetComponent<Slider>();
		VideoPanel = GameObject.Find("VideoPanel").GetComponent<Image>();
		BtnX = GameObject.Find("CloseButton").GetComponent<Button>();
		TotalTime = GameObject.Find("ZongTimeText").GetComponent<Text>();
		NowTime = GameObject.Find("NowTimeText").GetComponent<Text>();
	}

	public void OnEnable()
	{
		BtnReStart.onClick.AddListener(ClickReStart);
		BtnReStart.onClick.AddListener(ClickReStart);
		BtnX.onClick.AddListener(ClickBtnX);
		BtnPlay.onClick.AddListener(ClickKaishi);
		BtnPause.onClick.AddListener(ClickZanting);
	}
	public void OnDisable()
	{
		BtnReStart.onClick.RemoveListener(ClickReStart);
		BtnReStart.onClick.RemoveListener(ClickReStart);
		BtnX.onClick.RemoveListener(ClickBtnX);
		BtnPlay.onClick.RemoveListener(ClickKaishi);
		BtnPause.onClick.RemoveListener(ClickZanting);
	}

    // Use this for initialization
    void Start () {
		ClickKaishi();//是否自动播放

		tt = (float)vPlayer.clip.length;

		sliderVideo.maxValue = tt;

		min = (int)tt / 60;
		second = (int)tt % 60;
		TotalTime.text = string.Format("{0:D2}:{1:D2}",min.ToString(),second.ToString());
	}
	
	void Update () {
		//播放
        if (IsPlay)
        {
			vPlayer.Play();
			Index_t += Time.deltaTime;
            if (Index_t>=0.1f)
            {
				sliderVideo.value += 0.1f;
				Index_t = 0;
            }
        }
        else
        {
			vPlayer.Pause();
        }
		//进度条到底停止播放
        if (sliderVideo.maxValue-sliderVideo.value<=0.1f)
        {
			ClickReStart();
        }
		ChangeTime((float)vPlayer.time);
	}

	public void ChangeVideo(float value)
	{
		vPlayer.time = value;
	}

	/// <summary>
	/// 播放时间显示
	/// </summary>
	/// <param name="value"></param>
	void ChangeTime(float value)
	{
		min = (int)value / 60;
		second = (int)value % 60;
		NowTime.text= string.Format("{0:D2}:{1:D2}", min.ToString(), second.ToString());
	}
	/// <summary>
	/// 重播按钮
	/// </summary>
	public void ClickReStart()
	{
		sliderVideo.value = 0;
		vPlayer.time = 0;
	}
	/// <summary>
	/// 关闭按钮
	/// </summary>
	public void ClickBtnX()
	{
		VideoPanel.gameObject.SetActive(false);
	}
	/// <summary>
	/// 开始按钮
	/// </summary>
	public void ClickKaishi()
	{
        if (sliderVideo.value==sliderVideo.maxValue)
        {
			sliderVideo.value = 0;
        }
		videoImage.SetActive(true);
		IsPlay = true;
		BtnPause.gameObject.SetActive(true);
		BtnPlay.gameObject.SetActive(false);
	}
	/// <summary>
	/// 暂停按钮
	/// </summary>
	public void ClickZanting()
	{
		IsPlay = false;
		BtnPause.gameObject.SetActive(false);
		BtnPlay.gameObject.SetActive(true);
	}
}

同时还有另外一个脚本用来控制Slider的拖动和拖拽（两个接口，拖动和点击）

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

public class SliderChange : MonoBehaviour,IDragHandler,IPointerClickHandler
{
    /// <summary>
    /// 拖动改变视频进度
    /// </summary>
    /// <param name="eventData"></param>
    public void OnDrag(PointerEventData eventData)
    {
        VideoCrol.instance.ChangeVideo(VideoCrol.instance.sliderVideo.value);
    }
    /// <summary>
    /// 点击改变视频进度
    /// </summary>
    /// <param name="eventData"></param>
    public void OnPointerClick(PointerEventData eventData)
    {
        VideoCrol.instance.ChangeVideo(VideoCrol.instance.sliderVideo.value);
    }
}

在最后写完代码，组件做完之后，视频和参数等也需要调整一下

把整体打包了一个，包含代码和组件，可以看一下(上面的是打包好的网盘链接)
