Need help getting this rng to have more variation

Help and Feedback Scripting Support

working on a random gen script and it works although the variation between rolls isn’t that far apart, usually only about 10~ with 1000 rolls, i’m looking to get a decent more than this

currently the script rolls of off

  • if theres enough weight for the path
  • Chance

for example, longpath1 has 5 weight, and a 20% chance to roll. each roll the weight increases by 1-3, for longpath1 to generate there has to be atleast 5 or more weight and on generation it removes 5 weight

	for Path, PathInfo in pairs(Thingy) do
		if PathInfo.Weight <= CurrentWeight then
			local ChanceMult = {}
			local Chance = PathInfo.Chance
			local SpareWeight = CurrentWeight - PathInfo.Weight
			local Rolls = RollsSinceRolled[Path] - 5
			local Mullipier = 1
			
			if SpareWeight > 0 then
				table.insert(ChanceMult, SpareWeight/55)
			end
			if Rolls > 0 then
				table.insert(ChanceMult, Rolls/5)
			end 
			for i, v in ipairs(ChanceMult) do
				Mullipier += v
			end
			
			local ModifiedChance = Chance * Mullipier
			
			CanRoll[Path] = ModifiedChance
		end
	end

this basically helps lower chance paths be picked easier by

  • if the current weight is over the amount it takes to roll it, boost the rng
  • if it hasnt been rolled in over 5 rolls it boosts its rng

this does benefit the paths but doesnt have much variation behind it
so im asking on how i could add more variation to this
