Unity 待机视频图片轮播功能

原先写过一次这个功能，后来因为有点bug就删除了，现在补回来，虽然重新写了一次吧，但是还是感觉代码有点多=。=，如果大佬们有优化的方法希望能告诉我下Thanks♪(･ω･)ﾉ

 

先说明下，视频是通过AVProVideo插件加载的，所以你们可能需要个这个插件(*^▽^*)，图片就是通过WWW加载赋值在RawImage上的，这个比较简单。总体功能呢，就是当你的程序无人操作多长时间后开始图片和视频的循环播放（PC版），代码如下：

这个一开始StandVideoCanvas和RawImage是隐藏的

就是名字旁边的那个勾是不勾上的

using RenderHeads.Media.AVProVideo;

using UnityEngine.UI;

public class Loading : MonoBehaviour 
	{

		public GameObject Video;//加载Vedio的界面
		public GameObject RawImage;//加载图片的界面

		private DirectoryInfo dir;
		public float CountTimer = 0f;//计时时间，时间到了就开始播放
		private string path;
		private FileInfo[] videoFile;
		private int VideoIndex = 0;

			videoFile = dir.GetFiles("*.mp4", SearchOption.TopDirectoryOnly);
			ImageFile = dir.GetFiles("*.jpg", SearchOption.TopDirectoryOnly);
			if (ImageFile.Length != 0)
			{
				RawImage.GetComponent().texture = LoadPicture(0);
			}
