Unity封裝VideoPlyaer組件包含全屏+靜音+進度條+時長顯示

說明

??最近開發時需要播放視頻，回憶以前做過的專案，好多都有在Unity3D中播放視頻，每次都是自己重新實作一些功能，類似與進度條拖動，顯示時長等等，今天就是將其封裝一下，以后再用到直接拿來用，

包含的功能:

• 視頻進度條，可點擊進度條，拖動進度條
• 點擊視頻實作視頻播放與停止
• 全屏顯示
• 靜音
• 顯示視頻時長

播放界面：

腳本掛載：

EventTrigger:

全屏按鈕和靜音按鈕同理：

using UnityEngine;

public class TipCtrl : MonoBehaviour

    public GameObject tip;

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

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