Just a quick hack to share. This is the code I'm using to find your Terraria installation in RomTerraria 3.0.
static string GamePath = "";
static List<string> FindDetails = new List<string>();
static List<Process> GetProcessesByName(string machine, string filter, RegexOptions options)
{
List<Process> processList = new List<Process>();
// Get the current processes
Process[] runningProcesses = Process.GetProcesses(machine);
// Find those that match the specified regular expression
Regex processFilter = new Regex(filter, options);
foreach (Process current in runningProcesses)
{
// Check for a match.
if (processFilter.IsMatch(current.ProcessName))
{
processList.Add(current);
}
// Dispose of any we're not keeping
else current.Dispose();
}
// Return the filtered list as an array
return processList;
}
static bool FindGame()
{
var steamCandidates = GetProcessesByName(".", "steam", RegexOptions.IgnoreCase);
string steamFolder = String.Empty;
foreach (var p in steamCandidates)
{
try
{
if (p.MainModule.ModuleName.ToLower() == "steam.exe")
{
FindDetails.Add("Steam.exe process found.");
FileInfo f = new FileInfo(p.MainModule.FileName);
steamFolder = f.DirectoryName;
var d = f.Directory.GetDirectories("steamapps");
if (d.Count() > 0)
{
FindDetails.Add("Steamapps folder found.");
d = d[0].GetDirectories("common");
if (d.Count() > 0)
{
FindDetails.Add("Common folder found.");
d = d[0].GetDirectories("terraria");
if (d.Count() > 0)
{
FindDetails.Add("Terraria folder found.");
GamePath = d[0].FullName;
return true;
}
}
}
}
}
catch (System.ComponentModel.Win32Exception)
{
// Ignore this...means we were looking at SteamService.
}
}
if (FindDetails.Count == 0)
{
FindDetails.Add("Could not find a process named Steam.exe running.");
return false;
}
// Last chance: let's operate under the assumption that Terraria is in a different Steam install folder
string steamConfig = Path.Combine(steamFolder, @"config/config.vdf");
FindDetails.Add(String.Format("Checking Steam config at {0}", steamConfig));
GamePath = ParseConfig(steamConfig, @"InstallConfigStore/Software/Valve/Steam/apps/105600/installdir");
return !String.IsNullOrWhiteSpace(GamePath);
}
private static string ParseConfig(string steamConfig, string configNode)
{
Stack<string> keys = new Stack<string>();
string lastString = String.Empty;
using (StreamReader sr = new StreamReader(steamConfig))
{
while (!sr.EndOfStream)
{
string s = sr.ReadLine().Trim();
if (s.StartsWith("{"))
{
keys.Push(lastString);
}
else if (s.StartsWith("}"))
{
keys.Pop();
}
else if (s.StartsWith("\""))
{
var tokens = s.Split('\t').Where(a => !String.IsNullOrWhiteSpace(a)).ToArray();
lastString = tokens[0].Trim('\"');
if (tokens.Length > 1)
{
string key = String.Join("/", keys.ToArray().Reverse()) + "/" + lastString;
Debug.WriteLine(key, "ParseConfig");
if (key.Equals(configNode, StringComparison.InvariantCultureIgnoreCase))
{
return tokens[1].Trim('\"').Replace(@"\\", @"\");
}
}
}
}
}
return null;
}
