No. You just don’t implement rarity. You only want to make it as if there is rarity but in reality you will only get common items, and then you make a button to get legendary with robux.

[@alpha4194]

rarity while seeming initially hard isnt that bad when you get around to understanding tables, so i decided id program a simple lua weighted randomizer and send it here for people to reference if they manage to see this comment first we wanna start off with a table, which is essentially a list. However, each list is only really allowed to have one entry within each line, so to make things more optimized we are effectively putting a small list containing the NAME of the item, as well as its rarity. the rarity in question acts more as a 'frequency' meaning the higher the number, the more abundant the object would become. the template is essentially {(brick color),(frequency)} afterwards we are going to run code that makes a new table (list), that inserts each entry of the original table (list) the number of times of its frequency. Meaning the white brick in the situation (view below) would be written down on the list 100 times. We do this for every entry and effectively have a long imaginary list with 230 entries (in the situation im showing off below.) The final part of this is picking a random number from 1 to the number of entries we have, and just taking the object from the spot in the list! ------------------------- local OurExampleList = { {"White Brick",100}; -- common {"Purple Brick",70}; -- Uncommon {"Green Brick",50}; -- rare {"Orange Brick",10}; -- legendary i guess } local ImaginaryList = {} --imaginary list that is used for later to decide which specific brick we want by inserting the (total of) 230 possibilities into for CurrentIndex, CurrentListEntry in OurExampleList do for count =1,CurrentListEntry[2] do --see the [2]? This is important here because we are sorting through the original example list, which has mini lists and we want the rarities from the mini lists. CurrentListEntry is also technically one of these, which can be found from the CurrentIndex (meaning the mini list {"White Brick",100} is found when CurrentIndex is at 1) table.insert(ImaginaryList,CurrentListEntry[1]) -- places the current entry into the imaginary list, this is run as many times as its frequency end end local Result = ImaginaryList[math.random(1,#ImaginaryList)] --This is another index similar to [2], but we are picking a random entry, from 1 (the first entry) to the TOTAL number of entries (which is essentially 230) print(Result) ------------------------- sorry for lack of formatting or if I was to vague on any topics, but this is just some simple sample code that is a nice stepping stone to understanding absolute essentials to development

[@alpha4194]

this system integrates rarities AND parts to be part of a simple 18 line piece of code. if you really wanted to instead of printing the result you could use the string (the parts that say "White Brick", "Purple Brick", and so on and so forth) to identify parts you already stored. if we wanna do essentially what is being done here, we could (in place of print(Result)) replace with ----------- local PartClone = game.ServerStorage.Things:FindFirstChild(Result):Clone() Partclone.Parent = workspace.SpawnedParts ----------- This essentially finds the part by the name of our table entries meaning if your common/grey brick is named "White Brick" the code would be able to identify it within the storage folder, clone it, and throw it in workspace's folder very simply

[@alpha4194]

@@PeterMyler in an instance where this is an issue, you can instead of just contacting a single value, have the value represent something more. Lets say whitebrick had multiple variants but didnt wanna lower the odds of the other bricks by cluttering the pool, make whitebrick a folder in serverstorage, and run code that will pick a random object FROM that folder. Basically, check list, find desired category (common, uncommon, etc) and pick a random instance from your category. When picking the random instance, every instance should be equally weighted. If you want a code example lmk ill code one

[@slooshified_]

the way i made a rarity system is more focused on convenience of updating, so instead of making a table or list of rarities i just made a folder containing numberValues and effects of each rarities, so it picks a random number between the lowest and whatever the sum of all values are (all of which are handled by a "ipairs" sequence), which was NOT easy.. but saved me a lot more time adding more and more stuff on it

[@DpJordi]

I had a system for my now abandoned game. The rarity system was so advanced. It had to take like 8 values in mind when generating. It was basically an armour generator. Where each piece had multiple stats. But certain stats where handled differently. Before i started it, i thought it was gonna be super easy. shit was harder than anything ive done. It also had to work with data saving. I had like 5d array for each stat. Crazy. It used like 5 scripts in total. the rarity script was like 300+ lines. And when i code, i code to make it as efficient as possible. Then i realised, its roblox. It doesnt need to be this complicated. So now i stick to simpler games.

[@azurelava7796]

When you’re using the counter variable while looping through the rarities, this is called prefix sums, and it’s pretty useful for cases like these. But I would say that it’s better to just construct the prefix sums table right after your rarities table is initialized so that you can have faster runtime (especially if there is a lot of rarities).

[@Mycrow]

maybe its just me but could you just run a random function, like between 1 and 1000. then do a bunch of if statements and make then proportional to the rarity. So like common is 90 percent so if the number chosen from the random function was less than or equal to 900 then spawn the common brick? If you could'nt do that directly, you could store it in a variable then do another set of if statements to spawn the brick depending on what the variable is.

[@Platinum-Angel]

As a RNG game developer, I can explain how games add new items with new rarities not adding up to 100% while still being accurate. A first idea I had was to make, for example, common (50%) be added 50x in a table, and all that for each of the rarities, then returning a random one, except that's way too slow for huge numbers like 1,000,000, Roblox risks to crash. But then the ultimate solution is quite quite hard to understand : developers just use a rarity table like in this video, except their random generator function computes each "part"'s rarity weight and return a random part on its weight compared to other ones. Yep, that's quite hard to understand and redo but that's how it works. I spent hours documenting that subject and I made a pretty accurate rng system.

[@neverdaddy]

Very educational,deserves a sub 🎉

[@Hermit_Wish]

Thank you for this. And to all the viewers here, there's multiple variants of weighted RNG, I would highly recommend to try things out such as making an alternative to math.random(), or find another way to calculate the result. It's a complex system and there's no system that suits all, experiment with it. And with such, another method to this video is to add up all the weight values and multiplying it math.random() with nothing in the parentheses; from there, you go through each weight again and remove it from the accumulated weight that you got from multiplying till you reach 0 or less and return the item that triggered that check. However, by doing this method, you may see that high rarities will appear to be more common depending on the weight you assigned. Again, I highly recommend you to try things out and find new ways; step a little out of your comfort zone, but not by too much, learn from the behaviors and mistakes you come across.

[@azurelava7796]

If you’re using RNG, you use math.random(), because why would you want to create your own pseudo-random function? Unless it’s not random and you’re following a cycle of results. And you said that you could use math.random() * WEIGHT_TOTAL, but that’s literally the exact same thing. math.random(start, end) is equal to math.floor(math.random() * (start - end + 1)) + start.

[@Hermit_Wish]

@@azurelava7796 1. Yes, but only if you want it to repeat, it's the old way of doing RNG and still holds true to this day, that being said, you can easily update the seed with something unpredictable each time you are required to do so or whenever a button is pressed. 2. Right for the wrong reasons. try it first, you'll get different results as weird as that may sound.

[@Hermit_Wish]

something or someone removed my comment... 1. pseudo-random can be repeating if you want it to, there's ways to make it non-repeating. 2. while yes, math.random() * weight_total is the same as math.random(1, 100), it will yield slightly different results and I'll be honest, I don't know why, my best guess is the float point error, you'll also get slightly different results depending if you use a weight counter or remove weight from math.random(1, 100).

[@qrzone8167]

You can use your rarity "weight" as the maximum range for math.random and then a successful pull is when your random number is equal to 1. This makes it so you don't have to hand modify your weights every time you decide to add something rarer because adding something rarer just means the new entry will have a bigger weight number.

[@flameofthephoenix8395]

1:25 I've never programmed anything on "Roblox" before, but here's probably what I'd do in this situation, create a bunch of pets, none of them are intentionally favored, they are all on equal footing, you'll store on the server a quantity of each of these pets, every day increase the number of every pet by a fixed amount, such as 100 though it depends on how many people are playing your game, each time someone buys it decrease the number of pets, the cost of each pet depends on the number of those pets left compared to the other pets, with it being impossible to buy a pet that is out of stock entirely. Any pet that has far fewer left than all the other pets will get categorized as rare or legendary until it no longer has less than the other pets, you can add sparkles or something to these special pets, you can probably also make it possible to sell pets back if you want to make things more interesting, though it may be best to have a time limit on how long you can have the pet before losing the ability to sell it.

[@X5up0_]

so give everyone the pets and then make a rarity system so they can gamble to get pets that they actually own ?

[@flameofthephoenix8395]

@@X5up0_ Nope, the only thing getting pets for free is the server itself, then the server makes the cost of the pets equivalent to how much of that pet is in stock relative to other pets, this naturally will make some pets become harder to get because they happen to be preferred over the other ones for whatever reason, and sometimes the pets will even run out entirely. However, this comment had been made before I finished the video, I misunderstood what he was wanting to do, turns out he just wants some pets to be less likely than others based on hard-coded values.

[@X5up0_]

​@@flameofthephoenix8395 well what you are saying makes no sense, the way you are going to code the server getting free pets is actually a rarity system, the only difference between your idea and the video is that you want the legendry pet to be random as well not a hard coded yellow glowing part like in the video, and making the server choose it is also a rarity system which is bad because it could also pick a bad pet and make it "legendry", the only other logical way to do what you said is just making it as a market of pets in the game and the pets rarity is calculated based on revenue of each pet, which is as i said "giving free pets for everyone and then making them gamble using a rarity system to get the pets that they already own" and there is another problem , people won't have enough money to buy the high stats pets and they would for sure buy lower stats pets which kills the whole system there are ways to bypass stuff like this but the only ways i am currently thinking of makes the game not about pets instead about "STONKS"

[@petitcoke]

What software are you using to code this in?

[@alussk]

You could make a rarity system like he did and make it work by just making it check the first number in the table and if a number is less than the Random number it will get the table index of the rarity and add one to that and check the rarity of the one above the current rarity if that one is equal to or less thAn aswell, if it is less than then it will go to that rarity and check the same until it ends on 1 rarity. If the rarity is not less than the number it will check the next rarity. Bassically just if one number is wrong then go up if one number is right then check the next one if it’s also right and if the next one is wrong it will select the current number. If the number above is right, it will go to that one and check agian.

[@Happonyx]

Basically, this is how you would do it; 1. Generate random number from 1-5 2. If random number is not 5, make rarity common. 3. Else, if random number is 5, generate a new random number from 1 to 10. 4. If random number is not 10, make rarity uncommon. 5. Else, if random number is 10, generate a new number from 1-30. 6. If random number is not 30, make rarity rare. 7. Else, if random number is 30, make rarity legendary. Or, you could do something like this; 1. Generate a random number from 1-100 2. If random number is greater than 50, set rarity to common. 3. If random number is greater than 80, set rarity to uncommon. 4. If random number is greater than 95, set rarity to rare. 5. If random number is 100, set rarity to legendary.

@@Happonyx i see what you tried to do and this could work however this is pretty bad since you have to manually add in all the numbers yourself which isn't the greatest thing.

[@FrogsAreGods]

instead store a value of numbers that it has to be greater than and generate a random number from 1-100 store it as randomValue or something then loop through from legendary to common (must be in that order to ensure your probobabilties are acurate) checking if the value of each is greater less than randomValue so you would start to check if it was 100 (only number it could generate greater than 99) and go on untill 0

Technically you could make the table sorted by doing a number loop and then making a rarity table and going through the table using those numbers and then implement a system where the number is checked whether it’s in range of the allowed numbers and blah blah blah blah blah It would just be extra work for a system that’s effectively the same rarity system, albeit with more random steps

[@user-ox7ir1lu4y]

orrr ‘hey chat gpt. make me a rarity system.’ or even better ‘teach me how to make a rarity system’

[@alsoaspect]

pls make an RNG game where the better rarity you have, the better you are than everyone, for example if you have a better rarity you might be faster or get weapons or maybe even admin powers

[@SheekyDev]

Wait what? Adding rarities is hard? Man… I guess it is hard then… felt simple for me, but idk, maybe because I read a rarity thing a few years ago, and it’s just engrained in my mind now.

well what can i say? i was just thinking on how i could make a rarity system for my crate opening system. thanks

[@polyneptic]

you don't need to make your rarity weights total up to 100, but instead just do math.random(1, [sum of all your weights]) for your random number instead of 1 - 100.

[@Wyrmver]

that feels kinda icky even tho you got a 1 on the random number you only have a 1/4 chance of actually getting the legendary

Now I get why you think coding this is hard, and I agree.

[@justanormalplayer442]

Couldn’t you just put a value in each part and get a table and the bigger the number the amount of copies will be added to the table? (And then obviously choose a random part from the table)

[@justanormalplayer442]

Atleast that’s how I tackled rng

[@genericalt9746]

no it itsnt u just make it go backwards from most rare to least eg aura one gets rolled for 1/1mil if u get 1 u get that aura if no move on to aura 2 1/1000 and then if none are rolled u do common

As someone who has made my yeah rng game I can tell you that you’re making it sound a lot harder than it actually is lol The only mistake I’d actually watch out for is floating point precision stuff when the rarities are low. That’s when I ran into issues myself. Anyway it’s literally just simple math but you yapped for views

[@vyntax.mp3]

have you tested it with numbers that go up to 1e308? How are you doing luck system for yours?

[@EaZea]

@@vyntax.mp3 i add up all the probabilities and then they roll a random number between 0 and the sum. the luck works by the sum minus the number they rolled by 1 minus the luck value and adding that onto their original roll

[@user-jc3jn6uz5i]

why not just use this? function gamble() for name,chance module.rarity do local rolled = math.random(1,chance) if rolled == chance then return module.parts[name] end end end

[@TheEmeraldKidRE]

Can’t add luck to a system like that since it’s not weighted. Well - you can add luck to the system, but doing so is extremely inefficient since you have to manually remove rarities from the table as luck increases.

bruh just make a random number generator, then if the number from 0 to 50 - common, 51 to smth - rare, smth+1 to smth2 - epic, smth2+1 to 100 - legendary...

[@OrganicMilkGang]

for me rarity was kinda easy but everyone has their own problems

[@sparkywolfy8978]

Here’s one unique thing to do if anyone wanted to do a higher rarity chance: Let’s say you want Legendary to be (1 in 750k) and Epic to be 4.5% chance, basically calculate 750,000 * 0.045 OR (750,000 / 100) * 4.5 … (EDIT: You might want to use math.floor to round up the number if it has decimals e.g. 45.291736) To make it easier to add all together in the module.rarities, make a for loop that will add all the values up as a sub total. local subtotal = 0 for i = 1, #module.rarities do subtotal += module.rarities[i] end And just chance the code on Line 19 to… local randomNum = math.random(1, subtotal)
