Detailed Description

Game level layer over NetworkServer that decodes client messages and encodes server messages.

Decoded messages are pushed by the network thread into mutex protected queues that the game loop drains with the poll methods.

Constructor & Destructor Documentation

Server()

rtype::server::Server::Server ( std::uint16_t port )

explicit

Creates the server on a UDP port, without starting it.

Parameters

port	Local port to listen on.

Member Function Documentation

send()

void rtype::server::Server::send	(	std::uint32_t	connectionId,
		const std::vector< std::uint8_t > &	payload )

Sends already encoded messages to a client.

Parameters

connectionId	Destination connection.
payload	Messages, headers included.

pollInput()

bool rtype::server::Server::pollInput

(

InputEvent &

event

)

Pops the oldest Input message.

Parameters

event

Receives the message.

Returns

True if a message was popped.

pollConnectionEvent()

bool rtype::server::Server::pollConnectionEvent

(

ConnectionEvent &

event

)

Pops the oldest connection change.

Parameters

event

Receives the change.

Returns

True if a change was popped.

pollQueryEntity()

bool rtype::server::Server::pollQueryEntity

(

QueryEntityEvent &

event

)

Pops the oldest QueryEntity message.

Parameters

event

Receives the message.

Returns

True if a message was popped.

sendCreateEntity()

bool rtype::server::Server::sendCreateEntity	(	std::uint32_t	connectionId,
		const protocol::CreateEntityPayload &	payload )

Sends a CreateEntity message.

Parameters

connectionId	Destination connection.
payload	Message payload.

Returns

False if the payload is invalid or cannot be encoded.

sendDestroyEntity()

bool rtype::server::Server::sendDestroyEntity	(	std::uint32_t	connectionId,
		const protocol::DestroyEntityPayload &	payload )

Sends a DestroyEntity message.

Parameters

connectionId	Destination connection.
payload	Message payload.

Returns

False if the payload is invalid or cannot be encoded.

sendSnapshot()

bool rtype::server::Server::sendSnapshot	(	std::uint32_t	connectionId,
		const protocol::SnapshotPayload &	payload )

Sends a Snapshot message.

Parameters

connectionId	Destination connection.
payload	Message payload.

Returns

False if the snapshot has too many states or cannot be encoded.
