Locate Directories Dynamically

by ADMIN 31 views

Introduction

In the world of gaming, especially with games like Diablo II Resurrected, managing directories and files can be a daunting task. With the increasing complexity of game installations and the need for flexibility, it's essential to have a dynamic directory locator that can adapt to different user scenarios. In this article, we'll explore how to locate directories dynamically, ensuring that the launcher finds and uses the most-recently updated Reimagined folder that contains .d2s files.

Understanding Directory Locations

Before we dive into the dynamic directory locator, it's essential to understand the typical directory locations for Diablo II Resurrected. These locations include:

  • D2R Install: C:\Program Files (x86)\Diablo II Resurrected
  • D2RR Install: C:\Program Files (x86)\Diablo II Resurrected\mods\Reimagined
  • Saved Games: C:\Users\YourUser\Saved Games\Diablo II Resurrected\mods\Reimagined
  • Backups: C:\Users\YourUser\Saved Games\Diablo II Resurrected\mods\Reimagined Backups

These directories are typically located on the C: drive, but users may install the game on a different drive, use an external hard drive, or even enable OneDrive directories.

Dynamic Directory Locator

To create a dynamic directory locator, we need to consider the following scenarios:

  • Default Directory: The default directory is the one that the game is installed in, which is typically C:\Program Files (x86)\Diablo II Resurrected.
  • OneDrive Directory: If the user has enabled OneDrive, the directory may be located in a cloud storage location, such as C:\Users\YourUser\OneDrive\Documents\Saved Games\Diablo II Resurrected\mods\Reimagined.
  • External Hard Drive: If the user has installed the game on an external hard drive, the directory may be located on a different drive, such as E:\Program Files (x86)\Diablo II Resurrected\mods\Reimagined.

To locate directories dynamically, we need to use a combination of file system APIs and directory traversal algorithms. Here's a high-level overview of the process:

  1. Get the default directory: Get the default directory from the registry or a configuration file.
  2. Check for OneDrive directory: Check if the user has enabled OneDrive and if the directory is located in a cloud storage location.
  3. Check for external hard drive: Check if the user has installed the game on an external hard drive.
  4. Traverse the directory tree: Traverse the directory tree to find the most-recently updated Reimagined folder that contains .d2s files.

Implementation

Here's a sample implementation of the dynamic directory locator in C#:

using System;
using System.IO;

public class DirectoryLocator
{
    public static string GetDirectory()
    {
        // Get the default directory
        string defaultDirectory = GetDefaultDirectory();

        // Check for OneDrive directory
        string oneDriveDirectory = GetOneDriveDirectory();

        // Check for external hard drive
        string externalHardDriveDirectory = GetExternalHardDirectory();

        // Traverse the directory tree
        string directory = TraverseDirectoryTree(defaultDirectory, oneDriveDirectory, externalHardDriveDirectory);

        return directory;
    }

    private static string GetDefaultDirectory()
    {
        // Get the default directory from the registry or a configuration file
        return @"C:\Program Files (x86)\Diablo II Resurrected";
    }

    private static string GetOneDriveDirectory()
    {
        // Check if the user has enabled OneDrive
        if (Environment.GetFolderPath(Environment.SpecialFolder.OneDrive) != null)
        {
            // Get the OneDrive directory
            return Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.OneDrive), "Documents", "Saved Games", "Diablo II Resurrected", "mods", "Reimagined");
        }
        else
        {
            return null;
        }
    }

    private static string GetExternalHardDriveDirectory()
    {
        // Check if the user has installed the game on an external hard drive
        foreach (DriveInfo drive in DriveInfo.GetDrives())
        {
            if (drive.DriveType == DriveType.Removable)
            {
                // Get the external hard drive directory
                return Path.Combine(drive.Name, "Program Files (x86)", "Diablo II Resurrected", "mods", "Reimagined");
            }
        }
        return null;
    }

    private static string TraverseDirectoryTree(string defaultDirectory, string oneDriveDirectory, string externalHardDriveDirectory)
    {
        // Traverse the directory tree to find the most-recently updated Reimagined folder that contains .d2s files
        string directory = null;
        DateTime latestDate = DateTime.MinValue;

        if (Directory.Exists(defaultDirectory))
        {
            foreach (string file in Directory.GetFiles(defaultDirectory, "*.d2s"))
            {
                DateTime fileDate = File.GetLastWriteTime(file);
                if (fileDate > latestDate)
                {
                    latestDate = fileDate;
                    directory = defaultDirectory;
                }
            }
        }

        if (Directory.Exists(oneDriveDirectory))
        {
            foreach (string file in Directory.GetFiles(oneDriveDirectory, "*.d2s"))
            {
                DateTime fileDate = File.GetLastWriteTime(file);
                if (fileDate > latestDate)
                {
                    latestDate = fileDate;
                    directory = oneDriveDirectory;
                }
            }
        }

        if (Directory.Exists(externalHardDriveDirectory))
        {
            foreach (string file in Directory.GetFiles(externalHardDriveDirectory, "*.d2s"))
            {
                DateTime fileDate = File.GetLastWriteTime(file);
                if (fileDate > latestDate)
                {
                    latestDate = fileDate;
                    directory = externalHardDriveDirectory;
                }
            }
        }

        return directory;
    }
}
