Trouble with writing text to a .ini file
I am working on a small game project and I am trying to write a class that will allow a settings menu to write the recorded settings to a .ini file. However, I can't seem to get it to write to the file. I think I wrote the class correctly to do it based upon the MSDN article on the subject. But it just doesn't seem to work. Here is my class:
using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Text;
using UnityEngine;
//Used to allow other files to access the script by name
namespace INI
{
public class iniFile {
public string path;
string winDir=System.Environment.GetEnvironmentVariable("windir");
[DllImport("KERNEL32.DLL")]
private static extern long WritePrivateProfileString(string section, string key, string value, string filePath);
[DllImport("KERNEL32.DLL")]
private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);
/// INIFile Constructor.
public iniFile(string INIPath) {
path = INIPath;
}
/// Write Data to the INI File
public void IniWriteValue(string Section, string Key, string Value) {
long success = WritePrivateProfileString(Section, Key, Value, this.path);
Debug.Log (Section);
Debug.Log (Key);
Debug.Log (Value);
Debug.Log (path);
Debug.Log (success);
return;
}
/// Read Data Value From the Ini File
public string IniReadValue(string Section, string Key) {
StringBuilder temp = new StringBuilder(255);
int i = GetPrivateProfileString(Section, Key, "", temp, 255, this.path);
return temp.ToString();
}
}
}
Here is my call for the class in the main menu script:
if (GUI.Button (new Rect (Screen.width * guiGameplayApplyButtonPlaceX, Screen.height * guiGameplayApplyButtonPlaceY, Screen.width * guiGameplayApplyButtonSizeX, Screen.height * guiGameplayApplyButtonSizeY), "Apply")) {
ini.IniWriteValue("Gameplay","Difficulty","Test");
print ("Apply");
}
I created the instance of the class like this:
iniFile ini = new iniFile(@"..\settings\settingsTest.ini");
GetEnvironmentVariable("windir") and [DllImport("$$anonymous$$ERNEL32.DLL")] look extremely unportable. You also don't check for success and whatever i is supposed to be.
On that note, are you sure the folder that your supposed file is supposed to exist in also exists?
Sorry for the lag in response, I wasn't even sure if a moderator had finally approved this to be posted. To Graham Dunnett's question: I do not want to use playerPrefs because it uses the registry and using the registry is not the way I want the game to store settings. It makes it difficult to change settings quickly (without having to modify them in the code). I had planned on making a dev console to change settings that I don't want the player to access. ini files are what I am more familiar with.
To benproductions1 answer: I am not planning on porting the game to any other platform, so using that .dll file is not a problem for me. The folder does exist. However, that isn't a problem anyway because it will create the file if it doesn't exist already.
Also to your question about checking for success. I do cheeck and just send it to the debug log. It checks here:
long success = WritePrivateProfileString(Section, $$anonymous$$ey, Value, this.path);
Debug.Log (Section);
Debug.Log ($$anonymous$$ey);
Debug.Log (Value);
Debug.Log (path);
Debug.Log (success);
This shows up in the class.
As far as the "i" variable goes, I am not exactly sure what it does. It was show in the $$anonymous$$SDN article as needing to be there. However, it is irrelevant. It is in the function for reading the file not writing.
You could just use using System.IO, and write:
File.WriteAllLines(*path you want*, string [] {"Gameplay", "Difficulty", "Test"});
Note I use JavaScript primarily, and in JavaScript, the line is just:
System.IO.File.WriteAllLines(*path you want*, ["Gameplay", "Difficulty", "Test"])
I'm not too sure on using arrays in C# but I beleive that is how you do it.
