Enumeration Type Documentation

◆ ClientID

enum ClientID : uint32_t

'Unique' identifier to be given to clients

Enumerator
INVALID_CLIENT_ID 

Client is not part of anything.

CLIENT_ID_SERVER 

Servers always have this ID.

CLIENT_ID_FIRST 

The first client ID.

Definition at line 49 of file network_type.h.

◆ DestType

enum DestType : uint8_t

Destination of our chat messages.

Warning
The values of the enum items are part of the admin network API. Only append at the end.
Enumerator
DESTTYPE_BROADCAST 

Send message/notice to all clients (All)

DESTTYPE_TEAM 

Send message/notice to everyone playing the same company (Team)

DESTTYPE_CLIENT 

Send message/notice to only a certain client (Private)

Definition at line 79 of file network_type.h.

◆ NetworkAction

Actions that can be used for NetworkTextMessage.

Warning
The values of the enum items are part of the admin network API. Only append at the end.

Definition at line 90 of file network_type.h.

◆ NetworkErrorCode

The error codes we send around in the protocols.

Warning
The values of the enum items are part of the admin network API. Only append at the end.

Definition at line 110 of file network_type.h.

◆ ServerGameType

enum ServerGameType : uint8_t

Game type the server can be using.

Used on the network protocol to communicate with Game Coordinator.

Definition at line 42 of file network_type.h.

Variable Documentation

◆ MAX_CLIENT_SLOTS

const uint MAX_CLIENT_SLOTS = 256
static

The number of slots; must be at least 1 more than MAX_CLIENTS.

It must furthermore be less than or equal to 256 as client indices (sent over the network) are 8 bits. It needs 1 more for the dedicated server.
