I am working on a save file for an music software in unity. I found this but I don't understand why it's not working. If you can help I would be greatful! http://wiki.unity3d.com/index.php/FileBrowserWithColumns

I really need this code.

What's not working exactly?

killhead98 · May 11, 2014

Well. It tells me I need to set something up but I'm having a hard time to do so. And I'm not sure how to put this together.

You need to give us more details. What is this 'something' that you need to set up? Does the console give you any error messages, or warnings, anything?

Give us a detailed description of what is happening. Type out the exact error message here

killhead98 · May 12, 2014

Yes it does. It fals to run

Please use code tags when posting code. Read THIS.

There's a blank where there shouldn't be one:

Code (csharp):

VPosition=new Vector3(myData._iUser.x,myData._iUser.y,myData._iU ser.z);

From what I am gathering, I figure you don't know how to debug code. (which is 99% of your problem) Your expecting others to "figure this out" when your not willing to commit the time to learn the proper way to code and debug.

its a harsh reality. My suggestion is to read what these are and test each one with what is happening in the script:

Code (csharp):

using System.Xml;

using System.Xml.Serialization;

using System.IO;

using System.Text;

I will tell you from experience, Xml and Xml.Serialization read and write XML files. (An XML file is a text based file that uses tags to define structures of data. It is very similar to HTML, or web sites.)

System.IO is the input and output stuff for .net. This is what will read and write files as well as directories and other stuff.

System.Text is the portion that helps decode ASCII and Unicode stuff. It would help greatly in dealing with XML files.

Your task is to NOT, just use what someone else did, but to work on each of these and figure out what they do, and how to use them together. Remember, 99.9% of all programming is debugging, so learn how to do that as well.
