I'll give it a stab, but before I start, plz be more specific

@Frazzlee Yeah LOL!

As a GTA V mod user, it aggravates me when a script that involves a keypress doesn’t include an ini file. The key the author has selected may overlap with one of your controls and just piss you off. In order to prevent this, ini parsing can be implemented. With this class(below), you can read Booleans, integers, floats, or strings. For this example we will be reading strings.

The most common use of an ini is to configure a key press, and that’s what we’ll be doing. It gets a little complicated, but that's why I made this guide; to make ini parsing easier and to teach those who don’t know how to do it.

For this example I will be using my Quick Waypoint Remover, and xiaohe521’s “A Small Class to Read INI File”

Xiaohe521’s class is great because it is simple, stable, and open-source.

Let’s get started.
First make a file called delmarker.ini, put it in X:\Grand Theft Auto V, and paste the following into it:
[config]
button=0x08

The 0x08 is a key from here; YOU MUST USE THESE HEX CODES

Create a new header called “IniReader.h” and paste the following into it:

#pragma once // For Visual Studio
#ifndef INIREADER_H
#define INIREADER_H
class CIniReader
{
public:
CIniReader(char* szFileName);
int ReadInteger(char* szSection, char* szKey, int iDefaultValue);
float ReadFloat(char* szSection, char* szKey, float fltDefaultValue);
bool ReadBoolean(char* szSection, char* szKey, bool bolDefaultValue);
char* ReadString(char* szSection, char* szKey, const char* szDefaultValue);
private:
char m_szFileName[255];
};
#endif//INIREADER_H

Then create a new sourcefile called “IniReader.cpp” and paste the following:

#include "IniReader.h"
#include <iostream>
#include <Windows.h>

CIniReader::CIniReader(char* szFileName)
{
memset(m_szFileName, 0x00, 255);
memcpy(m_szFileName, szFileName, strlen(szFileName));
}
int CIniReader::ReadInteger(char* szSection, char* szKey, int iDefaultValue)
{
int iResult = GetPrivateProfileInt(szSection, szKey, iDefaultValue, m_szFileName);
return iResult;
}
float CIniReader::ReadFloat(char* szSection, char* szKey, float fltDefaultValue)
{
char szResult[255];
char szDefault[255];
float fltResult;
sprintf(szDefault, "%f",fltDefaultValue);
GetPrivateProfileString(szSection, szKey, szDefault, szResult, 255, m_szFileName);
fltResult = atof(szResult);
return fltResult;
}
bool CIniReader::ReadBoolean(char* szSection, char* szKey, bool bolDefaultValue)
{
char szResult[255];
char szDefault[255];
bool bolResult;
sprintf(szDefault, "%s", bolDefaultValue? "True" : "False");
GetPrivateProfileString(szSection, szKey, szDefault, szResult, 255, m_szFileName);
bolResult = (strcmp(szResult, "True") == 0 ||
strcmp(szResult, "true") == 0) ? true : false;
return bolResult;
}
char* CIniReader::ReadString(char* szSection, char* szKey, const char* szDefaultValue)
{
char* szResult = new char[255];
memset(szResult, 0x00, 255);
GetPrivateProfileString(szSection, szKey,
szDefaultValue, szResult, 255, m_szFileName);
return szResult;
}

Here is my script with a basic breakdown:

#include "script.h" // GTAV Library; This includes all GTA functions and stuff
#include "IniReader.h" // The ini reader header
CIniReader iniReader(".\delmarker.ini"); // Opens delmarker.ini
char *temp = iniReader.ReadString("config", "Key", "0x08"); // Gets the key and stores it in a char
DWORD key = strtol(temp, NULL, 0); // Converts the char into a DWORD
void update()
{
if (GetAsyncKeyState(key)) // Checks if key was pressed
{
UI::SET_WAYPOINT_OFF(); // Removes waypoint
AUDIO::PLAY_SOUND(-1, "SELECT", "HUD_FRONTEND_DEFAULT_SOUNDSET", 0, 0, 1); // Plays a sound
}
}
void main()
{
while (true) // Infinite loop
{
update(); // Calls the function defined above
WAIT(0); // Waits
}
}
// Ignore this below
void ScriptMain()
{
srand(GetTickCount());
main(); // Calls main function
}

Here is a more advanced breakdown:

CIniReader iniReader(".\delmarker.ini");
This creates a "CiniReader" called iniReader that is referring to delmarker.ini

char *temp = iniReader.ReadString("config", "button", "0x08");
This stores the string of text in a char
Syntax: (string section, string key, string defaultOption)
btw a "key" is just a part of an ini file, not a button on the keyboard.
DWORD key = strtol(temp, NULL, 0);
In order to get key presses, we need a DWORD, so the above converts a hex number into a DWORD
Syntax: (char *input, NULL, int base);
The base is the number before the x in the hex. For VK keys it's always 0...
GetAsyncKeyState(key)
Syntax: GetAsyncKeyState(DWORD key)

I hope this all made sense, reply with any questions

@Rjvisser01 Thank you SOOOO MUCH

I'll give it a stab. It will just take me some time.

So I've spent the last few days trying to get stupid ini files to work. I've had enough and need help.

I found this class to help read ini files: https://www.codeproject.com/kb/cpp/inireader.aspx

It is very well known and it works for most.

My compiler doesn't like iniReader.cpp, here is the output:

IF ANYBODY COULD HELP ME READ FROM AN INI FILE THAT WOULD BE GREAT. I'M FED UP WITH ALL OF VS' RANDOM QUIRKS AND BULLSHIT

Thanks.

@Rjvisser01 I'm very grateful for your help, however I don't know any C#. See, the problem with my code is probably my char* to DWORD conversion. Or simply my syntax of the iniReader class. If you could help me with that, that would be awesome!

@Rjvisser01 Thanks so much. I can't test it right now, but when I can, I'll let you know if it works or not.

Aight so this mod is supposed to delete a waypoint at the touch of a button for ease-of-use. I have a working version, but I'm working on a version that reads an ini file. It doesn't work... I have narrowed the problem down to something to do with the key or ini file. If someone could tell me what is wrong, I'd greatly appreciate that

Here is my source(Ignore my comments for dummies):

#include "script.h" // GTAV Library; This includes all GTA functions and stuff
#include "IniReader.h" // Reads .ini files: https://www.codeproject.com/kb/cpp/inireader.aspx
CIniReader iniReader(".\delmarker.ini"); // Opens delmarker.ini
const char temp = iniReader.ReadString("config", "Key", "VK_BACK"); // Gets the key and stores it in a char
DWORD key = (DWORD)temp;
void update()
{
if (GetAsyncKeyState(key)) // Checks if key was pressed
{
UI::SET_WAYPOINT_OFF(); // Removes waypoint
AUDIO::PLAY_SOUND(-1, "SELECT", "HUD_FRONTEND_DEFAULT_SOUNDSET", 0, 0, 1); // Plays a sound
}
}
void main()
{
while (true) // Infinite loop
{
update(); // Calls the function defined above
WAIT(0); // Waits
}
}
// Ignore this below
void ScriptMain()
{
srand(GetTickCount());
main(); // Calls main function
}

ini file:
[config]
Key=VK_ADD
