[游戏]服务器和客户端之间的同步策略[steeven]

Client

Player{ //Game.Me

1

void CommandA{

cmd = new Command(methodInfo,args[]);

server.channel.Send(cmd)

}

}

Unit{

event LocationChanged;

ID; //该单元的在游戏中的唯一标志

OwnerID;

//该单元属于谁

_Location;

Location{

8

set{

_Location = value;

if (LocationChanged != null)

LocationChanged(this,EventArgs.Empty);

｝

｝

}

Server

Channel{ //server端，每个channel属于某个用户

int ID; //Player id

2

void OnCommand{

server.CommandQueue.Add(ID,cmd);

}

}

Server{

void Main{

while(true)

3

if (CommandQueue.count>0)

processCommand();

}

4

ProcessCommand(){

Player p = FindPlayer(CommnadQueue.Peek().ID);

cmd.method.invoke(p,p.Peek().args)//如果不用reflection,需要一个大的switch

}

7

BroadcastCommand(players,cmd){

foreach(p in players)

p.channel.send(cmd);

}

}

Player{

//注意这里的Player是服务器端

5

void CommandA{

//check condition

unit.Location = xxx; '//perform command

//也许同步策略加到这里

}

Unit{

event LocationChanged;

ID; //该单元的在游戏中的唯一标志

OwnerID;

//该单元属于谁

_Location;

Location{

6

set{

if (value != _Location){ //发生变化

IList players = … //同步策略

Server.Broadcast(players,new command(ID,methodInfo,value));

}

_Location = value;

if (LocationChanged != null)

//也可能通过这里注册Location同步策略分析器

LocationChanged(this,EventArgs.Empty);

｝

｝

}

注释：

我更希望通过AOP把某些方法自动重定向或者同步到Server/Client端执行，编程上可以简化很多
