Networking

[AlejandroMJ]

Hi, I´m thinking about start a Ogre3D game project, but I must know if exists something to manage the network easier, thanks you

try rakNet

try rakNet

thank you:)

[AlejandroMJ]

and someone knows a free network engine????

[spacegaier]

Did you have a look at RakNet's website?

Depending on what you are going for, it is free!

Hi,

If you aren't looking to use a commercial networking library such as RakNet, I would suggest you take a look at enet: http://enet.bespin.org/

It's what I'm currently using for my game, and it works wonders. Though it may not be as feature-rich as RakNet, it's free and open-source.

That enet looks pretty good as well, i am seriously thinking about switching from RakNet, since i don't use all those rich features

A fellow moderator of mine on spieleprogrammierer.de (german gamedev community) has written a comparison of various ways to implement networking, including raknet, and his results suggest that raknet is not the non plus ultra lib for networking as many people tend to say: http://networklibsbenc.sourceforge.net/

I must add though that I currently use raknet in my project and for the moment it works great Also, I have not studied those results in detail.

Do you use the raknet serialization of game objects? I have read there is such a feature but i don't know how does it work, i do all sync myself.

do you mean RPC?
try bitstream: (only for Raknet4)

Code: Select all

	struct PlayerStateSync
	{
		PlayerStateSync()
		{
		}
		~PlayerStateSync()
		{

		}
		int playerIndex;
		//postion
		Ogre::Vector3 pos;
		//Quaternion
		Ogre::Quaternion qua;
	};

Code: Select all

	PlayerOperateSync pos;
	RakNet::BitStream bs;
		bs.WriteCompressed(pos);
		mRPC.Call("RPC_PlayerOperateResponse", &bs, HIGH_PRIORITY, RELIABLE_ORDERED, 0, RakNet::UNASSIGNED_SYSTEM_ADDRESS, true);
		return true;

and read the struct:

Code: Select all

		NetProtocal::PlayerOperateSync pos;
		bool read = bitStream->ReadCompressed(pos);
		RakAssert(read);

I don't, a while ago I have read that the built-in synch system has several flaws and would be rewritten in time (statement bei Rakkar on the forums). There is now a new synching system but I did not check it out. I feel quite comfortable doing it by hand anyways as its not that much work. I added different synching channels depending on the kind of action, user input (to server) and object states (from server) which are by far the most frequent types of messages are sent unreliable ordered on one channel, other things like join/leave etc. have their own channels and are sent reliable ordered. As I use client side prediction I think the standard RakNet synching wouldn't be an option for me anyway..

Detto, i do it all myself. I use the channels like you do, for physics there is unreliable ordered, for chat and important events reliable ordered and for entity creation reliable unordered (as my entity manager can handle mixed order even if entities depend on each other)
I believe TCP doesn't have such features
