How to make a Multiplayer Trainer

[zhaoyun333]

Since so many noobs are asking for one.

Noob Requirements:

Understanding of C++/C;
Understanding of Cheat Engine;

What noobs need:

A C++/C compiler (Ive seen so many noobs who take a c file and ask how to turn it to an exe)
Cheat Engine or a UCE (Undetected Cheat Engine)
A game

If you don't have any of the above, get it.

1. Start up your game
2. Start Up Cheat Engine
3. Open the process which runs your game
4. Depending on your game, if it has security, it will detect Cheat Engine. In this case, use a UCE. If you don't have one choose another game or stop reading.
5. Search for the value you want, eg: stamina, hp, ammo or w/e.
6. Add the value to your address list.
7. If the address is not randomly allocated and has a set address every time the game is run, then move to 8. You can find out if the address is set if you restart the game and the address is the same value, if it is a random value it is not set.
8. Copy the address.
9. Copy this code and follow the comments:

#include <windows.h>
#include <conio.h>
#include <dos.h>
#include <tlhelp32.h>
#include <stdio.h>

int value;	// will store value of address

bool dofreeze = false;		// determines if user activated value freeze

LPVOID value_addr   =	(void*) 0x00933410;  //take the address you copied and replace all the digits after 0x

void screen()	// output
{
	system("cls");	// clear the screen
	printf("Hello World! This is my first mutliplayer trainer!  nn");
	
	if(dofreeze) printf("[1] - freeze [ENABLED]n");	// if user enabled freeze, let him know!
	if(!dofreeze) printf("[1] - freeze  [disabled]n");		// same if it's disabled
	
}

int main(int argc, char* argv[])
{	
	HANDLE hProcessSnap;	// will store a snapshot of all processes
	HANDLE hProcess = NULL;	// we will use this one for the game process
	PROCESSENTRY32 pe32;	// stores basic info of a process, using this one to read the ProcessID from
	
	hProcessSnap = CreateToolhelp32Snapshot( TH32CS_SNAPPROCESS, 0 );	// make process snapshot

	pe32.dwSize = sizeof( PROCESSENTRY32 );		// correct size

	Process32First(hProcessSnap, &pe32);	// read info about the first process into pe32

	do	// loop to find the game process
	{		
		if(strcmp(pe32.szExeFile, "****.exe") == 0)	// replace **** with the process name of your game
		{
			hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pe32.th32ProcessID);	// open it, assigning to the hProcess handle
			break;	// break the loop
		}
	}
	while(Process32Next(hProcessSnap, &pe32));	// loop continued until Process32Next deliver NULL or its interrupted with the "break" above

	CloseHandle( hProcessSnap );	// close the handle (just fuckin do it)

	if(hProcess == NULL)	// self explanatory tbh
	{
		printf("Game not foundnn");
		getch();	// wait for a key press. otherwise the app will just close so fast when the process is not found, you wont know wtf happened.
	}
	else
	{
		screen();	// print the display
		
		char key = ' ';	// make a key variable to store pressed keys
		
		while(key != VK_ESCAPE)	// loop until user presses Escape
		{
			
			if(kbhit())		// if a key was pressed
			{
				key = getch();	// it is saved into "key"

				switch(key)		// here the commands are handled depending on the key that was pressed
				{				// case '1': ... break;  case '2': ... break; and so on
				case '1':
					dofreeze = !dofreeze;		// flip the dofreeze value true<->false to enable/disable it
					ReadProcessMemory(hProcess,value_addr,&value,4,NULL); //Read address and put value to value
					break;			
				
				case '2':
					shootf = !shootf;
					break;
				}
				screen();	// print the display after each key press
			}
			if(doammo){	// if barret freeze is activated
				
				WriteProcessMemory(hProcess, value_addr, &value, 4, NULL);}
				
			
		}
		CloseHandle(hProcess);	// close the handle
		
	}

	return 0;	// THE END
}

Save it as trainer.cpp
9. Compile it with a C++/C compiler
10. Run it
11. It should freeze the value of an address

I also cover this but more detailed in my '[Tutorial] Gamehacking 101' thread. This is an overly repetitive thread and if you just pasted that code it's probably best if people have questions they ask me in my thread instead for accurate answers. Thanks though.
