Cheating in multi-player gaming (particularly BF5)

[Quartz]

I've just been watching a video on cheating in BF5 - which I don't play - and it seems immediately obvious to me that BF5 violates one of the basic rules of MP gaming - don't trust the client. All these wallhacks, aimbots, and the like would be utterly useless if the client didn't have knowledge of targets until necessary. If a player is looking in a particular direction, only then does the client check the server for visible enemies, for instance. If a target is on the other side of a wall, then the client gets sent no information on the target's location. And so on.

What am I missing?

I expect that takes more server resources to achieve. Potential lag?

We're talking a round trip of less than half a second, probably less than a quarter of a second if the server is reasonably local. That's around human reaction time.

Half a second is massive when it comes to latency, especially in FPS.

But you still get that latency when you have peer to peer.

Not with client-side hit detection.

Ah, that's different. You're relying on the client to be honest, and with cheat software that reliance fails. As I mentioned in my OP, you don't trust the client.

 

[Quartz]

If you don't have some client side role it becomes much harder to do decent hit detection. You can't really win.

I played Aces High - an online flight combat simulator - in the days of modems and 300ms pings (the servers are in America) and hit detection was server-side and it worked fine.

You do if want to sell a playable online game with a ballistic/projectile shooting model.

I'm sorry, but I'm failing to see the link.

 

[Quartz]

I've played both and it's much of a muchness to me.

Hmm... I wonder if a solution might be for each client to run its own server as a separate process?
