unity3d屏幕截图功能

http://game.ceeger.com/Script/Application/Application.CaptureScreenshot.html

[java] 
function OnGUI(){ 
   if(GUI.Button(Rect(Screen.width*0.5-50,Screen.height*0.5-50,100,100),"screen")){ 
       Application.CaptureScreenshot("Screenshot.png"); 
   } 
} 

【c#】

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。

===========================================================

另外的方法

function ScreenshotEncode()
{
　　　// wait for graphics to render
　　　　yield WaitForEndOfFrame();

　　  // create a texture to pass to encoding
　　　　var texture:Texture2D = new Texture2D (Screen.width, Screen.height, TextureFormat.RGB24, false);

　　 // put buffer into texture
　　　　texture.ReadPixels(Rect(0.0, 0.0, Screen.width, Screen.height), 0.0, 0.0);
　　　　texture.Apply();

　　// split the process up–ReadPixels() and the GetPixels() call inside of the encoder are both pretty heavy
　　　　yield;

　　// create our encoder for this texture
　　　　var encoder:JPGEncoder = new JPGEncoder(texture, 75.0);

　　// encoder is threaded; wait for it to finish
　　　　while(!encoder.isDone)
　　　　　　yield;

　　// save our test image (could also upload to WWW)
　　　　File.WriteAllBytes(Application.dataPath + “/../testscreen-” + count + “.jpg”, encoder.GetBytes());
　　　　count++;
}

//简便方法看下面：

function OnMouseDown() {
　　　　Application.CaptureScreenshot(“Screenshot.png”);
}
