Function Documentation

G2D_DoRPC()

void G2D_DoRPC	(	struct GameFrameworkLayer *	pLayer,
		struct GameLayer2DData *	pData,
		u8 *	pRPCData,
		int	client
	)

do RPCs, call once a packet has been confirmed as a G2DPacket_RPC, call on both client and server

Parameters

pData
pRPCData
client	the number of the client who has sent the RPC, or -1 if the server has sent it and you are a client

G2D_Enqueue_RequestLevelData()

void G2D_Enqueue_RequestLevelData

(

)

TODO: should really be static to this file, probably.

G2D_Enqueue_Worldstate_Packet()

void G2D_Enqueue_Worldstate_Packet	(	struct GameLayer2DData *	pData,
		int	clientI
	)

Enqueue a packet that will cause all entities with bSerializeInNetworkUpdate == true to be saved into a packet, the serializer context will be SCTX_NetworkUpdate.

Parameters

pData	The Game2dLayer
clientI	The client index to send to - only relevant if you're the server

G2D_Extend_RequestLevelDataMessage()

void G2D_Extend_RequestLevelDataMessage

(

PacketExtensionNoArgsFn

fn

)

extend the packet that the client sends to request level data from the server. By default tile maps and serialized entities are included, this callback is called before this Game2DLayer managed level data is serialized - see WfNetwork.c

Parameters

fn	callback to call

G2D_FindEntityWithNetID()

struct Entity2D * G2D_FindEntityWithNetID	(	struct Entity2DCollection *	pCollection,
		int	netID
	)

try to find the entity with a given net ID

Parameters

pCollection	collection to search
netID	netID to search for

Returns

NULL if not found

G2D_IsClientConnected()

bool G2D_IsClientConnected

(

int

i

)

call from the game thread if you're the server to determine if a client is connected

Parameters

i

Returns

G2D_ParsePacket()

enum G2DPacketType G2D_ParsePacket	(	u8 *	pPacket,
		u8 **	pOutBody,
		int *	outHeaderSize
	)

G2D_ParseRPCPacket()

enum Game2DRPCType G2D_ParseRPCPacket	(	u8 *	packet,
		u8 **	pOutBody
	)

Parameters

packet
pOutBody

G2D_PollNetworkQueueClient()

void G2D_PollNetworkQueueClient	(	struct GameFrameworkLayer *	pLayer,
		float	deltaT
	)

G2D_PollNetworkQueueServer()

void G2D_PollNetworkQueueServer	(	struct GameFrameworkLayer *	pLayer,
		float	deltaT
	)

G2D_SendRPC()

void G2D_SendRPC	(	int	client,
		enum Game2DRPCType	type,
		void *	pRPCData
	)

Send an RPC.

Parameters

client	client to send to - send -1 if you're a client yourself
type	type of rpc to send
pRPCData	a struct appropriate to construct the rpc message - see src

IsNetIDTakenIterator()

bool IsNetIDTakenIterator	(	struct Entity2D *	pEnt,
		int	i,
		void *	pUser
	)
