ReadMemoryProcess in GTA IV

0x32789 · Jul 29, 2016

Hi guys! I am trying to make a GTA IV Hack but I faced a problem while doing..
(I dont know alot about Memory so please dont judge me by that)

Code:

   while(true)
	{
		int value = 65534;
		if(ReadProcessMemory(GTAIV.ProcessHandle, (LPCVOID)(GTAIV.BaseAddress+0x1540A20), &value, sizeof(value), NULL))
		{
			value += 0x20; 
			int value3 = 65534;
			if(ReadProcessMemory(GTAIV.ProcessHandle, (LPCVOID)value, &value3, sizeof(value3), NULL))
			{
				value3 += 0x8;
				int value2 = 65534;
				if(ReadProcessMemory(GTAIV.ProcessHandle, (LPCVOID)value3, &value2, sizeof(value2), NULL))
				{
					sprintf_s(iStr, "Val: %d (0x%08X)", value2, value2);
					print(iStr);
					/*
					WriteProcessMemory(GTAIV.ProcessHandle, (void*)address[2], &value, sizeof(value), NULL);*/
					Sleep(18000);
				}
				else
				{
					print("FAILED TO READ X2");
				}	
			}
			else
			{
				print("FAILED TO READ X1");
			}
		}
		else
		{
			print("FAILED TO READ X0");
		}
    }
    CloseHandle(GTAIV.ProcessHandle);

So in this I am trying to read firetype of weapon id 20(idk if I am reading of 32 or 20, But please correct me) in a array located at GTAIV.exe+0x1540A20,
Here is some info regarding the array

CWeaponInfo
See List_of_Weapons_(GTA4) for the arrays referred to in the struct.
Array of CWeaponInfo's can be found at GTAIV.exe+0x1540A20 (1.0.7.0).
[font=monospace, Courier]CWeaponInfo g_weaponInfos[60];

but dont shit post ok? I am waiting for a serious answer not trolololol nubz like u
it takes time, IVMP has no hacks at all even .asi mods arent possible cause of ivmp blocking them so read/write memory is my ONLY option.
then I can finally fuck aRGONATH and 31/32 players when my hack is done
