✅ Adding functionality to a call of duty mw2 (2009) steam tool

Hello, I have a tool which creates clean mw2 lobbies (free from mods etc). It has a kick feature which i use to kick players who are modding, but it does not ban them. To ban them i have to take their XUID from the tool and put it into a notepad file, but unfortunately my tool doesn't specify which XUID links to which players steam name. I have code which gets the steam name and i have code which grabs the XUID but i am struggling to put them together. Here is the code for getting the players steam name using hexadecimal memory address within cod mw2.

char * getPlayerName(int client)
{
    return (char*)(0x9978EC + (client * 0x52C));
}

char * getPlayerName(int client)
{
    return (char*)(0x9978EC + (client * 0x52C));
}

Here is the code it uses to kick players, the lobby size is 18.

if (ImGui::Button(getPlayerName(0), ImVec2(150, 25)))
                {
                    SV_GameSendServerCommand(0, 0, "t EXE_DISCONNECTED");

                }

if (ImGui::Button(getPlayerName(0), ImVec2(150, 25)))
                {
                    SV_GameSendServerCommand(0, 0, "t EXE_DISCONNECTED");

                }

I will post below the code which gets the XUID:

Here is the part of the code code which grabs the players XUID. It seems to use the cmd_argv function and then filters with NA_IP to get the XUID.

inline char* Cmd_Argv(int arg)
{
    if ((unsigned)arg >= cmd_argc[*cmd_id]) {
        return "";
    }
    return (char*)(cmd_argv[*cmd_id][arg]);
}
bool IsBanned(string xuid)
{
    std::ifstream file("xuidbans.txt");
    std::string str;
    while (std::getline(file, str))
    {
        
        if (str.find(xuid) != string::npos)
        {
            return true;
        }
        
    }
    return false;
}
void hk_PartyHost_HandleJoinPartyRequest(PartyData_s* party, int localControllerIndex, netadr_t from, msg_t* msg)
{

    char ip = ("%i.%i.%i.%i\n", from.ip[0], from.ip[1], from.ip[2], from.ip[3]);
    char v1[1024]; // [esp+Ch] [ebp-40Ch] BYREF


    if (from.type == NA_IP) {
        auto xuid = Cmd_Argv(2);

        bool rce = msg->cursize > 55;
        std::string xuidstr(xuid);

        std::transform(xuidstr.begin(), xuidstr.end(), xuidstr.begin(), ::toupper);
        printf("Received Join Party request from IP: %i.%i.%i.%i:%i | XUID: %s\n", from.ip[0], from.ip[1], from.ip[2], from.ip[3], from.port, xuidstr);

inline char* Cmd_Argv(int arg)
{
    if ((unsigned)arg >= cmd_argc[*cmd_id]) {
        return "";
    }
    return (char*)(cmd_argv[*cmd_id][arg]);
}
bool IsBanned(string xuid)
{
    std::ifstream file("xuidbans.txt");
    std::string str;
    while (std::getline(file, str))
    {
        
        if (str.find(xuid) != string::npos)
        {
            return true;
        }
        
    }
    return false;
}
void hk_PartyHost_HandleJoinPartyRequest(PartyData_s* party, int localControllerIndex, netadr_t from, msg_t* msg)

    if (from.type == NA_IP) {
        auto xuid = Cmd_Argv(2);

This is a C# discord, and we will not help you create a cheat.

It is written in c# but yes ok i will delete

Buddy•2y ago

That is not C# syntax

Thinker•2y ago

that is C++

j0dOP•2y ago

Apologies! It is used to combat cheaters if that helps at all

Thinker•2y ago

$cpp but again please don't write cheats

I literally fight against the cheaters, the game is swamped with people modding and doing nefarious stuff. I use this to create clean experiences for people
