Accepting player and data

Accepting the player

Next up is calling user_is_allowed_to_play. It is ideal to verify user status as early as possible after the player has been authenticated and the unique identifier is known.

In the example code we send a small response to the client if it is not allowed to play, but for timeouts and bans, simply dropping the connection will work just as well.

C/C++

if(packet_type::connect == p->id)
{
    const std::string &unique_id = 
        static_cast<const packet_connect *>(p)->name;
    
    uint32_t status = equ8_sm_user_status(unique_id.c_str());
    if(!user_is_allowed_to_play(from, unique_id, status))
    {
        std::cout << "Client '" << unique_id
            << "' not allowed to play (action: "
            << status << ")" << std::endl;
        return;
    }

C#

if(packet_type.connect == p.id)
{
    string unique_id = ((packet_connect)p).name;
    var status = equ8.session_manager.user_status(unique_id);

    if(!user_is_allowed_to_play(from, unique_id, status))
    {
        Console.WriteLine(
            "Client '{0}' not allowed to play (status: {1})",
            unique_id, status);
        return;
    }

Receiving data from the client

While the vast majority of Anti-Cheat data is sent directly from the client to the Anti-Cheat servers, a few packets need to be sent over the game’s existing data channel.

For instance, after the game server registers a client, an access token must be delivered to the game client so that it can connect to the Anti-Cheat servers directly.

Add a new packet to your game protocol for EQU8 data delivery, and feed the data to EQU8 as you receive the packet.

EQU8 will NEVER send more than 256 (0x100) bytes in a single packet.

C/C++

switch(p->id)
{
    case packet_type::equ8_data:
        std::cout << "EQU8 Received Data from user: '"
            << it->unique_id() << "' size: "
            << static_cast<const packet_equ8_data *>(p)->size
            << std::endl;
        equ8_sm_on_data_received(it->unique_id(),
            static_cast<const packet_equ8_data *>(p)->data,
            static_cast<const packet_equ8_data *>(p)->size);
        return;

C#

switch (p.id)
{
    case packet_type.equ8_data:
        var payload = ((packet_equ8_data)p).data;
        Console.WriteLine("EQU8 Received Data: user: '{0}' size: {1}",
            gc.unique_id(), payload.Length);
        equ8.session_manager.on_data_received(gc.unique_id(), payload);
        break;
