Technical solution to eliminate desync in single-player sessions

"

In this case, there are no "encrypted passwords" for the server to decrypt and validate. The only things that are "deterministic" about the random number seeds are the emergent game simulation results they produce. The only way for the server to "validate" the client's results as legitimate is to reproduce its own simulation of the game session. That time-shifted, open-loop simulation would be subject the same timing discrepancies that a real-time simulation would incur. Such a system would be incapable of producing reliable results.

If you don't trust the client and the server has to verify everything the same way that it currently does, how exactly does anything change?

Yes, the server validates the state hash by performing a simulation of it against the current in-memory snapshot. This would be around 1 second of simulation. It is not going to experience any timing discrepancies because of the short segmented simulations.

Please read my main post over and over, until you can answer this question yourself.

While not a traditional MMO, and whether they admit it or not, GGG is working on making an MMO influenced game.


I mean just from the top of my head:

Online only
Global chat
Solid player models to make you aware of your positioning in a party
Guilds to get people playing together
Nerf to Auras to make you share auras in your party
No auction house, making people communicate to make trades
Faster leveling while in a party

I'm sure there is much more if I thought about it a bit. Anyways.

Your post completely ignores security, get back to us when you address this

Let me help you than, if you don't trust the client. Everything that is sent to you must be verified and corrected as needed. Therefore, if the client said that it moved from x to y via path B, but the server says that is impossible and you are now stuck on obstacle C. The client and server are now out of sync. The client now has to be corrected. Please elaborate on how your system prevents this and how this is not desync.

Tantabobo: You can put any number you want in there, I just used 1 second because Rhys_GGG used it. Any number is fine really. That's up to GGG, not me, it has no impact on the result.
