GameSrv is a lightweight online game framework written with Golang.Inlcude 3 types server： Gateway， GameSrv and World .It can be used in many types of online game.Tcp network use gnet

Build

Linux

git clone https://github.com/wesley-zhong/gameSrv.git
cd gameSrv
make  clean/build

Windows

Open directly with Goland or VsCode

Run And Test


make run  //start the server

// client only run linux or mac os
//start client

cd build/client
./client

How To Use

start server

// msg Register
controller.Init()

//package receive handler
handler := &networkHandler.ServerEventHandler{}
	
//start server
network.ServerStart(viper.GetInt32("port"), handler)

register client msg process handler

func Init() {
	core.RegisterMethod(int32(protoGen.ProtoCode_LOGIN_REQUEST), &protoGen.LoginRequest{}, login)
	core.RegisterMethod(int32(protoGen.ProtoCode_HEART_BEAT_REQUEST), &protoGen.HeartBeatRequest{}, heartBeat)
}

function implement

func login(ctx network.ChannelContext, request proto.Message) {
// logic code here

// wrap inner msg and inner msgId to  send to game server 
log.Infof("====== loginAddr=%s now loginCount =%d", ctx.RemoteAddr(), PlayerMgr.GetSize())
client.GetInnerClient(client.GAME).SendInnerMsgProtoCode(protoGen.InnerProtoCode_INNER_LOGIN_REQ, existPlayer.Pid, innerRequest)
}

func heartBeat(ctx network.ChannelContext, request proto.Message) {
	player := ctx.Context().(*player.Player)
	heartBeat := request.(*protoGen.HeartBeatRequest)
	log.Infof(" context= %d  heartbeat time = %d", player.Context.Sid, heartBeat.ClientTime)

	response := &protoGen.HeartBeatResponse{
		ClientTime: heartBeat.ClientTime,
		ServerTime: time.Now().UnixMilli(),
	}
	//send to client
	player.Context.Send(int32(protoGen.ProtoCode_HEART_BEAT_RESPONSE), response)
}

InnerClient : server's tcp connection

//init InnerClient
clientNetwork := networkHandler.ClientEventHandler{}
network.ClientStart(&clientNetwork,
	gnet.WithMulticore(true),
	gnet.WithReusePort(true),
	gnet.WithTCPNoDelay(0),
	gnet.WithTicker(true),
	gnet.WithCodec(network.NewInnerLengthFieldBasedFrameCodecEx()))
		
//build a connection from GateWay(client.GATE_WAY) to Game(client.GAME)
client.InnerClientConnect(client.GAME, viper.GetString("gameServerAddr"), client.GATE_WAY)

Deploy

Docker
