Selecting randomly from known probability?
I have these four variables:
local RarityBasic = 0.4 -- The probability. local RarityRare = 0.3 local RarityLegendary = 0.2 local RarityExotic = 0.1
Where the number is the probability. I want a way of randomly choosing one of them taking into account the probability that each thing has.
The output would be something like:
print("Rarity: "..Rarity)
>> Rarity: Basic
How would I do this?

Use math.random and covert each number to a string. For different raritys, have several numbers equal one string Viking359 161 — 6y

math.random isn't actually random. awfulszn 394 — 6y

You could create a random number from 0 ~100 and use that as a %? User#5423 17 — 6y

How would I manipulate the randomly generated number though? shadow7692 69 — 6y

Do something like this :
math.randomseed(tick())
local number = math.random(1,10)
if number == 1 then
print("Rarity : Exotic")
elseif number >= 2 and number <=3 then
print("Rarity : Legendary")
elseif number >= 4 and number <=6 then
print("Rarity : Rare")
elseif number >= 7 and number <= 10 then
print("Rarity : Basic")
end
It basically assigns different chances to each rarity so the exotic has a 10% chance, legendary has 20% chance, etc.

Make sure this is a server script, and where is the script? Viking359 161 — 6y
