The trailer for the upcoming installment of GTA was released shortly after it was leaked on social media. The best-selling video game franchise will return to Vice City, a fictional location based on Miami.
Oh, it’s not just P2P. There are ways to make P2P networking work, but GTAO has several inherent networking flaws.
One of them is that a client is understandably responsible for computing things around it (pedestrians etc). This is fine in itself but what if two people meet and one leaves? What happens to the things it was computing?
Well, clients can send a packet that means “don’t worry I got it from here” that they can send to other clients to tell them that from now on, they will be the one computing a specific thing. Non-hacked clients are programmed to always agree. No matter what the thing is.
Unrelated, here are a few example of the types of things that are affected by this:
pedestrians
NPC cars
various props
empty cars
cars with other players in them
other player’s avatars (which are considered special pedestrians)
various item pickups
vehicles other than cars
various scripts that have to do with single-player interactions, such as the casino wheel, slots, biker gang actions, etc.
This means that as a hacker, you get to decide what happens with the car somebody is driving, and change whatever attributes you want about it.
Note that this also means that any client is free to spawn any of the above items at any point, including the money bags spawned by tellers when you rob them (R* does do some checks when you tell them your new account balance but it’s really not that hard to bypass). Any client is also free to change anything about these items. Color, license plate, engine upgrades, hell, even straight up engine variables. And other clients have to accept that that happened, because that’s how the protocol is written.
This is just for regular stuff though. Hackers can already massively affect the game this way but there is some stuff they can’t do. Until they become the most senior client of the session (for example by crashing anyone more senior than them through various exploits - patched in their own clients of course).
Being the oldest client in a session means you become the script host, and when you’re script host, you unlock additional things that everyone agrees are your responsibility, such as what time of day and weather it is. Overall being script host isn’t that desirable because it doesn’t grant stuff that is really strong, just stuff that has wide impact (for example I think the script host has the capacity to make it winter anytime, but it’s just not that funny to do that after the 2nd time).
I’m probably going to pirate it with the way they’ve treated gta online
Rockstar Gaming disapproves
Yeah they treated it really bad and the cheaters were everywhere and toxic playerbase is not really good.
And after i looked up how gta online handles serverside/clientside code, i can understand how easy it is just to cheat.
yeah, basically everything is p2p from my understanding. and the anticheat is basically nonexistent (technically a good thing for linux gaming).
