(Tutorial) Starting WoW-Memory Reading/Writing

[punkedalex]

please someone enlight me how do i get this baseaddress cuz all i get is 0x400000 ...

[DarkLinux]

MEMORY_BASIC_INFORMATION mbi;
uint Traverse;

VirtualQueryEx(hProcess,(LPVOID)Traverse,&mbi,sizeof(mbi));

mbi.BaseAddress

[punkedalex]

found how , thanks

[abuckau907]

MEMORY_BASIC_INFORMATION mbi;
uint Traverse;

VirtualQueryEx(hProcess,(LPVOID)Traverse,&mbi,sizeof(mbi));

mbi.BaseAddress

Process.MainModule.BaseAddress == very first mbi's base? why doesn't that seem right?...


alex, if you're on an older machine (without ASLR) it will always be that number. (I'm on windows xp sp3 - same thing)

I dont want to burn your thread up. (Wish i could borrow that sarcasm someone used a few pages ago) But Just a quick question, and slightly bent topic. But what is a good book to learn C#(Forgive me if I sound like I was born addicted to crack). But I want to run an experiment. Please only people who have a clue respond via Inbox. **And i'll tell you the experiment,**-****Shhh****

[Linda513]

you're writing to memory, isn't that detectable?

[DarkLinux]

Everything is detectable... Even the bots that do not write to memory... It just depends on how bad Blizz wants your ass XD

[homer91]

Yes. Yes it is.

I'm getting a 'Win32Exception was unhandled' exception, meaning that it doesn't have the rights to execute the project, if I start it up as administrator it works, though it doesn't work when I just press F5. Is there any way I can start up my project as administrator automatically?

[flowtek333]

Stany8. ofc there is a way. what program do you use to make the program in? visual studio? if y open visual studio with adminstrator.


//edit: for more info about the error you get. make f.eks. a try function to see if it can handle it or show the error

Add an app manifest.

Hi, I completed this tutorial, my character name is printed to the listbox but I'm not getting the xyz coordinates, can someone put a newbie like me in the correct way?.

I'm ingame and running the app as admin, here is the little code.

private void button1_Click(object sender, EventArgs e)
        {
            
            BlackMagic wow = new BlackMagic();
            wow.OpenProcessAndThread(SProcess.GetProcessFromProcessName("Wow"));

            IntPtr baseWOW = wow.MainModule.BaseAddress;

            string playername = wow.ReadASCIIString((uint)baseWOW + 0xE28468, 256);
            float playerx = wow.ReadFloat((uint)baseWOW + 0x7E8);
            float playery = wow.ReadFloat((uint)baseWOW + 0x7EC);
            float playerz = wow.ReadFloat((uint)baseWOW + 0x7F0);
 
            listBox1.Items.Add(playername);
            listBox1.Items.Add(playerx.ToString());
            listBox1.Items.Add(playery.ToString());
            listBox1.Items.Add(playerz.ToString());
 
        }

The xyz values I'm getting are 0.

Thanks in advance.

[flowtek333]

Decodex by finding the xyz with BaseWOW aint the best idea at all..

use movementdata to get xyz. most allways 100% right

uint movementdata = wow.ReadUInt(playerbase + 0x100);
float playerx = wow.ReadFloat(movementdata + 0x10);
float playery = wow.ReadFloat(movementdata + 0x14);
float playerz = wow.ReadFloat(movementdata + 0x18 );

ps.. offset old, find the offset on the forum

Good morning.

I have inject dll with ChatListener for 3.3.5a:

WoWChat.h

#ifndef WOWCHAT_H
#define WOWCHAT_H

class WoWChatClass
{
private:
	unsigned int index;
	struct WoWChatStruct
	{
		long long SenderGuid;
		unsigned int Unknow[13];
		char FormattedMessage[3000];
		char Text[3000];
		unsigned int MessageType;
		unsigned int ChannelNumber;
		unsigned int Sequence;
		unsigned int Time;
	} *pWoWChatStruct;

public:
	WoWChatClass();
	~WoWChatClass();
	long long getSenderGuid() { return pWoWChatStruct->SenderGuid; }
	char* getFormattedMessage() { return pWoWChatStruct->FormattedMessage; }
	char* getText() { return pWoWChatStruct->Text; }
	unsigned int getMessageType() { return pWoWChatStruct->MessageType; }
	unsigned int getChannelNumber() { return pWoWChatStruct->ChannelNumber; }
	unsigned int getSequence() { return pWoWChatStruct->Sequence; }
	unsigned int getTime(){ return pWoWChatStruct->Time; }

	WoWChatStruct* getPointWoWChat() { return pWoWChatStruct; }
	void setPointWoWChat(unsigned int address) { pWoWChatStruct = (WoWChatStruct*)address; }

	char* CheckNewMessage();

	void Init();
};

#endif

WoWChat.cpp

void WoWChatClass::Init(){
	setPointWoWChat(Memory::Read<unsigned int>(Offsets::Chat::ChatBuffer_start));
	index = Memory::Read<unsigned int>(Offsets::Chat::ChatBuffer_count);
}

WoWChatClass::WoWChatClass(){
	setPointWoWChat(Memory::Read<unsigned int>(Offsets::Chat::ChatBuffer_start));
	index = Memory::Read<unsigned int>(Offsets::Chat::ChatBuffer_count);
}
WoWChatClass::~WoWChatClass(){ delete this->pWoWChatStruct; }

char* WoWChatClass::CheckNewMessage(){
	unsigned int newIndex = 0;
	unsigned int newAddress = 0;
	newIndex = Memory::Read<unsigned int>(Offsets::Chat::ChatBuffer_count);
	if (newIndex == index) return NULL;

	if (newIndex < index){
		for (; index < 60 ; index++){
			newAddress = Offsets::Chat::ChatBuffer_start + (Offsets::Chat::ChatBuffer_next * index);
			setPointWoWChat(newAddress);
			if (getText()[0] == '.') {
				if (index == 59) index = 0; else index++;
				return getText();
			}
		}
		index = 0;
	}

	for (; index < newIndex; index++){
		newAddress = Offsets::Chat::ChatBuffer_start + (Offsets::Chat::ChatBuffer_next * index);
		setPointWoWChat(newAddress);
		if (getText()[0] == '.') {
			if (index == 59) index = 0; else index++;
			return getText();
		}
	}

	return NULL;
}

Sometimes when i set a new pointer (setPointWoWChat(newAddress)) in the char* WoWChatClass::CheckNewMessage() i can get issue:

pWoWChatStruct->SenderGuid; // <--memory reading is impossible, but a new pointer of struct is fine

PS: I'm just using dereferencing like reading of variables and struct

[ioctl]

Your code is a little confusing, and I'm not familiar with the chat message structures, but that "delete" in the constructor is a very obvious bug. You don't own that memory; don't try to delete it. Bizarre things will happen. Maybe that's causing your problems, maybe not. In fact, I would just get rid of that member -- keeping your class structured like this is going to give you headaches; the less state variables you have, the better. I would do this:
* Move all of those methods for retrieving chat fields (text, channel number, etc.) onto the WoWChat struct. If you want to avoid c++ fanciness, just leave all the fields public.
* Add a method that returns index of the latest message, however that is determined (looks like a ring buffer?), and a method that advances the index.
*

ChatBuffer_start + ChatBuffer_next * index

feels like you should have a struct of size ChatBuffer_next, and just do ChatBuffer[index].
* Now CheckNewMessage() can look something like:

if (index != GetLatestIndex()) {
    index = GetNextIndex();
    return ChatMessageAt(index);
} else {
   return nullptr;
}

Calling code would look like:

WowChat* message;
while (message = wow_chat_manager.CheckNewMessage()) {
  DoSomethingWithMessageText(message->getText());
}
