Random/rng system

[regal topaz]

What is the best way to make random/rng like slime rng

[silver cargo]

weighted tables

[regal topaz]

What about luck boosts

[silver cargo]

weight * luckMultiplier

[regal topaz]

So if i have
Common = 1000
Legendary = 1
And if i have luck 1000?
Common will be
1,000,000 and legendary
1000?

[long pawn]

yeah

Weighted systems are best for this

[covert nimbus]

local rarityTable = {
  {Rarity = "Epic", Chance = 1/25},
  {Rarity = "Rare", Chance = 1/5},
  {Rarity = "Uncommon", Chance = 1/2},
  {Rarity = "Common", Chance = 1}
}

local luck = 175 -- Calculated as a procentage

local function roll()
  local rng = math.random()
  print("RNG Before Luck:", rng)

  rng = rng / (1 + luck / 100)
  print("RNG After Luck:", rng)
  
  for _, rarity in rarityTable do
    if rarity.Chance >= rng then
      print("Obtained:", rarity.Rarity)
      print("Chance: 1 in " .. 1 / rarity.Chance)
      break
    end
  end
end

roll()``` Here's something I wrote up

just don't go negative and you should be good
