uMod - Log bandit camp wheel stop positions? - Rust

Posted 5 years ago

There is already a SHED load of scientific research on "weighted" game wheels as in the real world.
However this is a "game" game wheel, it depends if the physics in the game is realistic..

(intersting fact... a few decades ago, they found that painted/printed numbers on the ping pong balls used in many "ramdom" country lotteries was enougth to change the "randomness")

But there is enougth realworld examples of people using a very good RNG, to only then F** it up in programming or something they overlooked..
Take a look in the computer security field..

as regards "White thunder" even if he finds an issue with "time" it could be highly server specific..., number of plugins, CPU, etc.
We have already seen examples of servers, that fail to fully comple the assigned tasks due to loading.

The velocity will be distributed evenly between 7 and 10 due to RNG. I tested with various custom velocities and found that this will cause it to land between approximately 4.1 and 5.6 spins. The velocity decays exponentially so it won't be an even distribution between those two points (it's weighted towards 4.1).

Here's the code that causes the velocity to decay if someone wants to figure out the rest. By plotting the decay, you can determine the probability that a given position on the wheel will be hit.

float num = Mathf.Clamp(180 * velocity, 0f, 180);
velocity -= UnityEngine.Time.deltaTime * Mathf.Clamp(velocity / 2f, 0.1f, 1f);
if (velocity < 0f)
{
    velocity = 0f;
}
wheel.Rotate(Vector3.up, num * UnityEngine.Time.deltaTime, Space.Self);

I mean, yeah. That's the short of it. But even if the spin ranges didn't overlap, it'd still be a biased roulette wheel. The 5 that touches the 3 should not exist. If the game designer meant for it to be this way, or said "good enough" in their quest to stop a net positive spread wager over all possibilities... I don't know what the creator of this game thought tbh. I'd like to buy them a beer and listen.

Care to elaborate? It sounds like you're saying the pattern you expect to find isn't Rust specific. If you have the source code and can find out the time it takes for the wheel to make one rotation, you can already predict the distribution. Not sure why you need the scientific method. Presumably you can rebuild the wheel outside of Rust as well.

Sorry for the delay m8, I'll gladly show you. I've been speed running Beach to Bandit, seeing how fast I can run there to recycle whatever I grab and gamble to 2k.

Then I give away the winnings.

If you ever want to hop in Rust with me, you pick a server, I'll show you first hand what it is I'm doing.

It all started with a sequence of 5-1-1-20. A pattern that shouldn't have been occuring at all, let alone several times, to different people, different servers, across the span of over a year now, had turned me into some D-list Rain Man. Since I posted about it a year ago, I've decompiled the movements of the wheel the hard way - analog. The code can wait. You can show me in the code why it does this thing after you see it. I'd rather just play blackjack tbh. Rust isn't fun when bandit camp is my ATM. Hit me up. https://www.gonzorust.com/discord #gambling channel, @me

before people laugth at "RNG", being predicatble......

just go back to 2008 and see what the NSA did with the elptic curve RNG's

they don't laugh so much as call me a fucking idiot or a liar... or worse, lucky.

the scope of how random it could be is so narrow that certain sequences appear over and over. shooting fish in a barrel.

i beat my speedrun time, previously 4179 seconds, to only 1399 seconds from beach to 2k scrap by gambling. I beelined from spawn beach to bandit camp, grabbing only crates, recycled everything, and won 2k scrap in less than 10 spins. the only luck that comes into play would be not getting killed on the way there.

infinite sadness for the scrappy boi. im running out of rust stuff to do. :(
please halp.

There are worse things in life that being called an idiot... or liar...
Most of it is done by angry people who are incapable of defending a stance they have taken...
Sometimes it makes me cry.... that we think ourselves so advance that we don't need the Collosseum anymore...

Here is a quick side note. This is still just postulating, however when I was studying computer science. We did a class on random. When it comes to computers there is no such thing as a random number. Most of it is done with an algorithm applied to something external. In my CS class, it was applied to the system clock. So in C++ the RNG command would return you a number picked from X to Y. Based on the system clock. So what's interesting about your findings is that the pattern is only different on different Rust servers. I wonder what would make unity behave this way? Might be worth it to spin up a Unity engine. Using the code above to create your own wheel. Some different tests could be applied to each time you boot your engine seeing if that seeds the RNG differently.

I think that Rust is using random in many places and at least client can never guess where and how many times it was used which should make the wheel unpredictable even if the random is pseudo.

I ent killed the gambling wheel in the Bandit Camp. It will not come back. Restarted the server hoping it would come back - no luck. Anyone have an idea how to get it back? Thank you in advance

yes you can get it back
but it is some sortof work!!!
I used the same workflow for when i made the big digger head dissapear.

1. start a new clean map, with the same seed & size
2. go to the bansit camp and get the co-ords of the now reinsated wheel.
3. go back to your old map
4. respawn the wheel at the co-ords you noted down from the virgin map.

"respawn the wheel at the co-ords you noted down from the virgin map."

How exactly does one do this step?

generally, if you check in the consode "F1" it will show the item removed & all the coords.
or you can use the inbuilt admin rust commands to remove it, and once again it will give you the co-ords.

finally to put it back use the inbuilt rust admin commands.
Entity.spawn, spawn...., what ever is the most suitable for your situation / client/server.
a quick search for the admin commands will give you the info you need.

The data is stored in the map save file, so as long as you do a save before, you can recover.
once it is as you like, do another "save" to write it into the map save file.
