Does anyone know of or have a demo that shows multiplayer networking actually working in A7? I want something to show some people who are considering using A7 for an online multiplayer game.

http://www.opserver.de/ubb7/ubbthreads.php?ubb=showflat&Number=283739#Post283739

and it is fun game and source code released. and plays fine over the internet.

you mean local a7 networking, right?
cause I made a demo a while back with anet, though I wouldn't call it a finished game...

I mean a game that works over the internet.

I just tried that Survive game, and man its really laggy, but I assume it's programmed wrong..it seems like the movement isn't done on the client side.

Does anyone know of a internet multiplayer A7 game that actually works well on the internet..?

Hi matt,

the movement of survive isn't well programmed, thats right. currently the input is send to the server who sends it back to all clients, including the one who send it in the first place. This way, the movement is in sync on all clients.
Of course you could get the source code and change that, but it wouldn't be too easy.
I'm currently working on an mmo base using the ANet plugin, that should be less laggy (cause it uses diablo-syle movement with the mouse).

What kind of online game is it going to be? the faster, the harder to implent, cause you'd have to write your own solid algorithms for movement prediction and error correction..

there is one commercial 3DGS online multiplayer project: glider - collect 'n kill" but it was made with A6.

"the faster, the harder to implent, cause you'd have to write your own solid algorithms for movement prediction and error correction.."

more on that topic here, darkinferno sent me this a while back:

I think this page is the reason there's so few online mutliplayer games made with 3dgs. Most people don't even find the time to finish their single player games; mutliplayer takes longer. Much longer.

I know quite a few good and promising ANet projects that are currently in the works, and I bet at least 2 or so of them will be sold. But I can't show you any finished completed projects in that area, probably because ANet's not been around for too long.

Interesting detail analysis in the Source-Engine link.

It states once again, that these high-speed games like shooters
dont work in a pure Server-dictated environment.
But the client also doing movement predition and
the server adjusting for time-lags in client inputs.

Thats the reason why they can come around most lag-issues.
(eg. the client-player moves instantly when hitting move, due
to client prediction)
But it also shows how complex it is to implement.

idiot question here but....

would it not be faster and easier to just send vector pan and animation data from client to server, then server echos it out to the other clients(or they just read from the server) while all mesh data(what the models looks like, animations, textures)is stored on the clients...???

I'm no MMO programmer, I have no clue...

Server and clients dont send the mesh / model data, but
only frame and positiondata, etc.

The problem for "real" commercial games is, that the
server can not trust the clients to send unaltered data.
A client could just send its local position, that is
directly controlled by the player, plus other actions like shooting.
This would actually work pretty fast, and is a solution
for hobby games. But its also easy to cheat on it.

Plus: the server has a hard time to syncronize
this data, to determine collisions and
hits properly. (in high latency internet setups)

That is exactly what I meant, all the assets stored on the client side(for obvious reasons...bandwidth, & common sense)...as for the rest...like I said...not a clue.
