Question Read directory in build version

Hi,

I want to get all files from directory, but in production the folder does not appear.

Code (CSharp):

1. private static readonly string themePath = Application.dataPath + "/data/";
2.  
3.     public static void ReadFiles()
4.     {
5.         if (dataRead) return;
6.         DirectoryInfo dir = new(themePath);
7.         FileInfo[] info = dir.GetFiles("*.xml");
8.         foreach (FileInfo f in info)
9.         {
10.             XmlDocument doc = new();
11.             doc.Load(f.FullName);
12.  
13.             XmlElement root = doc.DocumentElement;
14.             string name = root.SelectSingleNode("/theme-data/name").InnerText;
15.             Color32 background = HexToColor(root.SelectSingleNode("/theme-data/background-color").InnerText);
16.             Dictionary<Regex, Color32> highlight = new();
17.             foreach (XmlNode node in root.SelectSingleNode("/theme-data/highlights").ChildNodes)
18.             {
19.                 Regex regex = new(node.ChildNodes[0].InnerText);
20.                 Color32 color = HexToColor(node.ChildNodes[1].InnerText);
21.  
22.                 highlight.Add(regex, color);
23.             }
24.  
25.             themes.Add(new Theme(name, highlight, background));
26.             themeNames.Add(name);
27.         }
28.         dataRead = true;
29.         if (PlayerPrefs.HasKey("editorTheme"))
30.             currentTheme = GetThemeByName(PlayerPrefs.GetString("editorTheme"));
31.         else
32.             currentTheme = GetThemeByName("Default");
33.     }

What can I do to make that folder appear, or somehow fix the issue?

 

You cannot use anything from the System.IO namespace to read assets from a build.

Here are three alternatives:

You may use Resources.Load<T>() or Resources.LoadAll<T>() (simplest)

You may use Addressables or Asset Bundles (most-powerful)

You may stream non-Unity assets ONLY out of the StreamingAssets mechanism.

 

Thanks, that helps
