void OnGUI(){                if(GUI.Button(new Rect(10,70,50,50),"ScreenShot")){                    StartCoroutine(ScreenShot());  //协程调用        }            }        IEnumerator ScreenShot(){            int width = Screen.width;            int height = Screen.height;            yield return new WaitForEndOfFrame(); //去掉协程试试看会发生什么。            Texture2D tex = new Texture2D(width,height,TextureFormat.RGB24,false);//设置Texture2D            tex.ReadPixels(new Rect(0,0,width,height),0,0);//获取Pixels                       tex.Apply();//应用改变            byte[] bytes = tex.EncodeToPNG();//转换为byte[]　　　　　　　Destroy(tex);            Stream flstr = new FileStream(@"d:\1.png", FileMode.Create);//文件操作            BinaryWriter sw = new BinaryWriter(flstr, Encoding.Unicode);                       sw.Write(bytes);            sw.Close();            flstr.Close();                }

　　另一种方法：

using UnityEngine; using System.Collections; public class example : MonoBehaviour { 　　void OnMouseDown() 　　{ 　　　　Application.CaptureScreenshot("Screenshot.png"); 　　} }   function OnGUI(){    if(GUI.Button(Rect(Screen.width*0.5-50,Screen.height*0.5-50,100,100),"screen")){        Application.CaptureScreenshot("Screenshot.png");    } }

这张Screenshot.png图片被存在了当前工程的子目录下了。
