基于Texture2D 实现Unity 截屏功能

本文主要是介绍基于Texture2D 实现Unity 截屏功能，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

实现

截屏

Texture2D texture = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
texture.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
texture.Apply();

存储 

byte[] array = ImageConversion.EncodeToPNG(texture);
if (!Directory.Exists(filePath))
{Directory.CreateDirectory(filePath);
}
File.WriteAllBytes(filePath + "/" + fileName, array);

问题 

ReadPixels was called to read pixels from system frame buffer, while not inside drawing frame.

直接使用截屏会出错，可使用协程或在OnPostRender 中处理来解决，具体参见链接文章。
