Possible to create a networked game with multiple players moving around?

by John Klimek · in Torque Game Builder · 01/19/2009 (5:44 am) · 7 replies

I've owned TGB and TGE for quite a while but never really used them but I think I'm going to give TGB another try and see what I can do, but I'm wondering if it's possible to create a networked game with several players moving around.

Also, how would I keep players position/rotation/velocity synchronized across the network?

I've been talking to people in GameDev and it seems like you need to implement client-side prediction, interpolation, extrapolation, etc.

Is it possible to synchronize player movement (and other aspects) more easily in TGB? What all would be involved?

Thanks!

Look into the checkers demo that ships with TGB. It's a great example of TGB networking.

Thanks, but isn't that purely turn-based?

I'm talking about moving two players around in realtime. Not as fast or "twitchy" as an FPS but still moving around none-the-less...

You're correct, it is turn based. From what I understand, TGB networking is "event based" so can be extended from turn based, but will not (in it's current form) be able to run close to real-time networking. Long in short, you going to need to test the waters with what you want to do.

Have you considered using TGE and fixing the camera to simulate a 2d environment? That way you have all the perks of Torque networking...

John, it can be done. There's nothing wrong with "event-based", but you won't get the greatest performance from it. The whole "real-time" networking is a myth and the sooner people realize that, the sooner they'll learn to work well with the tools they have. Granted, TGB's networking isn't ideal for a real-time game, but if the action is reasonable slow, it could work.

Thanks for the replies everybody.

Can you give me some ideas on how to make it work? For example, would I just need to send player position every few milliseconds or do I need also need interpolation, etc, etc...?

Maybe describe your game a bit?

Every few milliseconds might be OK, but with event-based, you may want to consider any time you have a change of state.

What you are purposing sounds like a MMO. The mmoworkshop project might be of interest to you.
