求教,Unity3D 如何 截屏高于分辨率 的 texture

比如用unity3D导出的应用跑4K分辨率,想截取左下4分之一屏的 保存一张 texture,分辨率也为4K,有没有大神知道?? 使用ScreenCapture.CaptureScreenshot() 虽然能整体放大数倍,但是无法设置具体的截图范围和大小。 类似以下方法可截取自己设定的位置和大小,但是大小无法大于当前应用运行 的分辨率。 ``` IEnumerator SavePhoto(Rect rect,string name) { yield return new WaitForEndOfFrame(); Texture2D t = new Texture2D(rect.width, rect.height); t.ReadPixels(new Rect(0, 0, rect.width, rect.height), 0, 0, false); //距X左的距离 距Y屏上的距离 // t.ReadPixels(rect, 0, 0, false); t.Apply(); byte[] byts = t.EncodeToJPG(100); File.WriteAllBytes(path_Save + name + ".jpg", byts); } ```

<div class="post-text" itemprop="text"> <p>I'm working on something with Unity3d MySQL Db. I am passing values through <code>$_GET</code> PHP method but I'm having trouble with strings with white spaces when I store them into the assigned tables.</p> <p>Let's say I have an InputField which gets the string I need.

<div class="post-text" itemprop="text"> <p>I'm developing an Android and iOS game, I need to call the php pages to collect and enter data into the database mysql.</p> <p>Sending and reception of data works properly, the problem is that the data sent is not encrypted, but this I can solve it with the ssl certificates, in order to have all the data send encrypted.</p> <p>The other problem is that with some appropriate programs (example: Charles Proxy) you can see the address pointed to my php file, and consequently you can resubmit the packet over and over again.</p> <p>For example:</p> <p>This is my test.php:</p> <pre><code>$code = $_POST['SecretCode']; if($code == "secretcode") { // Connect to DB and increment 'i' value } </code></pre> <p>This is my C# code in Unity3D:</p> <pre><code>public IEnumerator test() { WWWForm form = new WWWForm(); form.AddField("SecretCode", secretcode); WWW www = new WWW("http://sitename.com/test.php", form); yield return www; if(www.text != "") { // Returned value } } </code></pre> <p>Now, if from my game I call the 'test ()' function, the php called check the security code, and if it is right, will increase the variable on the database.</p> <p>While the game sends this request, Charles Proxy can see the request and therefore I can with Charles resend endlessly the request, increasing endlessly the value in the database.</p> <p>To make you understand better I'll show you a picture that sums it all:</p> <p><a href="http://postimg.org/image/x3owvt5il/" rel="nofollow">http://postimg.org/image/x3owvt5il/</a></p> <p>Finally there is a way to make invisible the php file or make it look unknown?

<div class="post-text" itemprop="text"> <p>I have a web server which contains a sql database. There are two "users" to this server/database.
