Help with luck module

module.Spin = function(luckTimes,player,final)
	local decimalPlaceMulti = 10000000000000 --allows for decimals, every 0 is 1 decimal place (so the limit right now would be 0.0000001)
	
	local number

	if luckTimes >=1 then
		number = Random.new():NextInteger(0, (100*decimalPlaceMulti)/luckTimes) -- We get a random number between 0 and 100.
	else
		number = Random.new():NextInteger(0, (100*decimalPlaceMulti)*luckTimes) -- We get a random number between 0 and 100.
	end
	
	number = number/decimalPlaceMulti
	local chosen = nil-- The item that will be chosen.
	for i, item in ipairs(module.Luck) do -- Iterate over each item
		if number < (item.Chance * 200) then -- If the number is less than the Chance, this is the chosen item.
			chosen = item
		end
	end
	
	if final == true then
		if chosen.Chance*200 <= 0.15 then
			script.Parent.Send:InvokeServer(chosen[1],chosen.Color,chosen.Chance)
		end
	end

	return chosen
end

The script sort of works, but i have a problem as want abysal to be the rarest ‘aura’, however the chance is actually based off the difference between the closest rarest aura and the closest less rarest aura. I really dont know how to fix this, so thanks for your help.

maybe you should look into a weighted luck system.

Weighted Chance System

This tutorial requires a good understanding of Lua! Hello! Today I will teach you how to make a Weighted Chance System. To those that do not know, this is a system that will do something based on chance. For this tutorial, I will be using a prize system. You want to start by having a table of prizes and the chances of getting them ranging from 0-1. [image] Next, you want a Variable called Weight to hold a value of 0. [image] Now, you want to iterate through the PrizeTable and add the…

As mentioned by @WickdSuper, definitely use a weighted system. Floating point arithmetic can be quite dubious and unnecessarily complex.

Side note, abyssal*

Hi thanks for helping, do you know how i can get the chance from a weighted system?

The chance is equal to weight/sum of weights
