[游戏开发]Unity封装VideoPlyaer组件包含全屏+静音+进度条+时长显示

说明

??最近开发时需要播放视频，回忆以前做过的项目，好多都有在Unity3D中播放视频，每次都是自己重新实现一些功能，类似与进度条拖动，显示时长等等。今天就是将其封装一下，以后再用到直接拿来用。

包含的功能:

• 视频进度条，可点击进度条，拖动进度条
• 点击视频实现视频播放与停止
• 全屏显示
• 静音
• 显示视频时长

播放界面：

脚本挂载：

EventTrigger:

全屏按钮和静音按钮同理：

主要脚本：

        }
    }
}

鼠标移入全屏或静音按钮小标签提示脚本：

using UnityEngine;

public class TipCtrl : MonoBehaviour
{
    [Header("提示标签：")]
    public GameObject tip;

    private void Start()
    {
        tip.SetActive(false);
    }
    public void OnPointEnter()
    {
        tip.SetActive(true);
    }

    public void onPointExit()
    {
        tip.SetActive(false);
    }
}
