21 int width = Screen.width;
22 int height = Screen.height;
23 Texture2D tex = new Texture2D(width, height, TextureFormat.RGB24, false);//要保存图片的大小
24 //截取的区域
25 tex.ReadPixels(new Rect(0, 0, width, height), 0, 0);
26 tex.Apply();
27 //把图片数据转换为byte数组
28 byte[] buffer = tex.EncodeToPNG();
29 Destroy(tex);
30 //然后保存为图片
31 File.WriteAllBytes(Application.persistentDataPath + "/" + System.DateTime.Now.ToFileTime() + ".png", buffer);

上面的代码参考了Unity的脚本手册,实现同时按下LeftAlt和L键进行屏幕截图。下一篇文章我将实现通知中心的功能,将截图完成的信息显示出来。
