unity3d屏幕截图功能

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。之前在android上面一直不知道路径，后来把所有路径试玩了总算ok了，呵呵~~~在android上截取的图片存在Application.persistentDataPath上面，在pc上存在Application.dataPath。

private var www:WWW;private var image:Texture;private var path:String;function Awake(){   Application.CaptureScreenshot("Screenshot.png");}function Start () {   if(Application.platform==RuntimePlatform.Android){      path=Application.persistentDataPath;   }else if(Application.platform==RuntimePlatform.WindowsPlayer){      path=Application.dataPath;   }else if(Application.platform==RuntimePlatform.WindowsEditor){      path=Application.dataPath;      path=path.Replace("/Assets",null);    }     www=new WWW("file://"+path+"/Screenshot.png");   yield www;   image=www.texture;}function OnGUI(){    GUI.Label(Rect(0,0,400,50),"1:"+Application.persistentDataPath);    GUI.Label(Rect(0,50,400,50),"2:"+Application.dataPath);    GUI.Label(Rect(0,100,400,50),"3:"+Application.temporaryCachePath);    GUI.Label(Rect(0,150,400,50),"4:"+Application.absoluteURL);    GUI.Label(Rect(0,200,400,50),"5:"+Application.streamingAssetsPath);     GUI.DrawTexture(Rect(0,250,300,200),image);}

在编辑器上各种路径：

    

在pc上各种路径：

      

在web上各种路径：

    

在android上面各种路径：

   

第二种方法：

import System.IO;var www:WWW;var image:Texture;function Start () {}function OnGUI() {    if(GUI.Button(Rect(0,0,100,100),"png")){        writeFile();    }    if(Input.GetKey(KeyCode.Escape)){       Application.Quit();    }          www=new WWW("file://"+path);      image=www.texture;      GUI.Button(Rect(Screen.width-100,0,100,100),image);  }private var fileName : String = "jietu2";private var path:String;function writeFile(){    path=Application.dataPath;    var tex : Texture2D= new Texture2D(Screen.width,Screen.height,TextureFormat.RGB24, false);    tex.ReadPixels(Rect(0,0,Screen.width,Screen.height),0,0);    tex.Apply();    var bytes : byte[]=tex.EncodeToPNG();    Destroy(tex);    var thisName : String = fileName+".png";    if(Application.platform==RuntimePlatform.Android){        path="/mnt/sdcard/"+thisName;    }else{       path=path+thisName;    }        var cache = new FileStream(path, FileMode.Create);    cache.Write(bytes,0,bytes.Length);    cache.Close();}

后来我又试了一下这个方法，结果又不行了，运行到var cache = new FileStream(path, FileMode.Create);就不运行了。
