Lua math.random bug?

[silveralol]

well, I have some problems with a script to load maps of the world change fury gate...
my script

local config = {
    [1] = { -- Ab'dendriel
        storage = 1,
        fromPosition = Position(32673, 31716, 7),
        toPosition = Position(32687, 31728, 7),
        mapName = 'ab',
    },
    [2] = { -- Ankrahmun
        storage = 2,
        fromPosition = Position(33257, 32834, 7),
        toPosition = Position(33272, 32846, 7),
        mapName = 'ankrahmun',
    },
    [3] = { -- Carlin
        storage = 3,
        fromPosition = Position(32258, 31842, 7),
        toPosition = Position(32266, 31852, 7),
        mapName = 'carlin',
    },
    [4] = { -- Darashia
        storage = 4,
        fromPosition = Position(33292, 32365, 7),
        toPosition = Position(33307, 32377, 7),
        mapName = 'darashia',
    },
    [5] = { -- Edron
        storage = 5,
        fromPosition = Position(33214, 31912, 7),
        toPosition = Position(33227, 31928, 7),
        mapName = 'edron',
    },
    [6] = { -- Kazordoon
        storage = 6,
        fromPosition = Position(32572, 31976, 7),
        toPosition = Position(32578, 31983, 7),
        mapName = 'kazordoon',
    },
    [7] = { -- Liberty Bay
        storage = 7,
        fromPosition = Position(32344, 32689, 7),
        toPosition = Position(32357, 32702, 7),
        mapName = 'liberty',
    },
    [8] = { -- Port Hope
        storage = 8,
        fromPosition = Position(32526, 32708, 7),
        toPosition = Position(32537, 32720, 7),
        mapName = 'port',
    },
    [8] = { -- Thais
        storage = 9,
        fromPosition = Position(32260, 32157, 7),
        toPosition = Position(32275, 32171, 7),
        mapName = 'thais',
    },
    [10] = { -- Venore
        storage = 10,
        fromPosition = Position(32828, 32080, 7),
        toPosition = Position(32836, 32087, 7),
        mapName = 'venore',
    }
}
local FuryEnabled = true
function onStartup()
    if FuryEnabled then
        local randTown = config[math.random(#config)]
        if not randTown then
            return true
        end
        Game.loadMap('data/world/furygate/' .. randTown.mapName .. '.otbm')
        print(">> The fury gate are in " .. randTown.mapName .." today.")
        Game.setStorageValue(GlobalStorage.FuryGates, randTown.storage)
        return true
    end
end

this always will be in edron ... I don't know why ...
I have another script that is the same thing, the math.random always stay in one "number"

local TeleportToJaul = Position(33545, 31263, 11)
local TeleportToObujos = Position(33419, 31255, 11)
local TeleportToTanjis = Position(33639, 31230, 11)
function onStartup()
    local rand = math.random(1, 100)
    if rand < 20 then
        local teleportJaul = Game.createItem(1387, 1, Position(33558, 31282, 11))
        if teleportJaul:isTeleport() then
            teleportJaul:setDestination(TeleportToJaul)
            Game.createMonster("Jaul", Position(33538, 31269, 11))
            print(">> Deeplings World Change reveals Jaul today.")
        end
    elseif rand >= 20 and rand < 40 then
        local teleportObujos = Game.createItem(1387, 1, Position(33438, 31248, 11))
        if teleportObujos:isTeleport() then
            teleportObujos:setDestination(TeleportToObujos)
            Game.createMonster("Obujos", Position(33434, 31262, 11))
            print(">> Deeplings World Change reveals Obujos today.")
        end
    elseif rand >= 40 then
        local teleportTanjis = Game.createItem(1387, 1, Position(33649, 31261, 11))
        if teleportTanjis:isTeleport() then
            teleportTanjis:setDestination(TeleportToTanjis)
            Game.createMonster("Tanjis", Position(33646, 31243, 11))
            print(">> Deeplings World Change reveals Tanjis today.")
        end
    end
    return true
end

the second script is always in the number > 20 < 40...

add line
local randTown = math.randomseed(os.time())
before
local randTown = config[math.random(#config)]

and
local rand = math.randomseed(os.time())
before
local rand = math.random(1, 100)

 

[silveralol]

add line
local randTown = math.randomseed(os.time())
before
local randTown = config[math.random(#config)]

and
local rand = math.randomseed(os.time())
before
local rand = math.random(1, 100)

I can ask why declare two times the same variant ?
I use it, is correct?

local randTown = math.randomseed(os.time())
randTown = config[math.random(#config)]

local rand = math.randomseed(os.time())
rand = math.random(1, 100)

works fine... but I don't know if is the correct way to use it, anyway, thank you for it :3

TFS 1.2 already seeds math.random on startup, I believe you have removed this line from your startup.lua.

math.randomseed(os.mtime())

It is only necessary to call this once.

It's a recent change from november 12.
