Macro Definition Documentation

DEFAULT_SERVER_NAME

#define DEFAULT_SERVER_NAME   L"Unnamed Server"

MAX_CLIENTS

#define MAX_CLIENTS   41

Number of peers to allocate for the enet host.

Limited by ENET_PROTOCOL_MAXIMUM_PEER_ID (4096).

At most 8 players, 32 observers and 1 temporary connection to send the "server full" disconnect-reason.

Variable Documentation

CHANNEL_COUNT

constexpr int CHANNEL_COUNT = 1

constexpr

FAILED_PASSWORD_TRIES_BEFORE_BAN

constexpr int FAILED_PASSWORD_TRIES_BEFORE_BAN = 3

constexpr

g_NetServer

CNetServer* g_NetServer = NULL

Global network server for the standard game.

HOST_SERVICE_TIMEOUT

const int HOST_SERVICE_TIMEOUT = 50

static

enet_host_service timeout (msecs).

Smaller numbers may hurt performance; larger numbers will hurt latency responding to messages from game thread.

NETWORK_BAD_PING

constexpr u32 NETWORK_BAD_PING = DEFAULT_TURN_LENGTH * COMMAND_DELAY_MP / 2

constexpr

Once ping goes above turn length * command delay, the game will start 'freezing' for other clients while we catch up.

Since commands are sent client -> server -> client, divide by 2. (duplicated in NetServer.cpp to avoid having to fetch the constants in a header file)
