How do I use math.randomseed(tick()) within a function or is that unnecessary? [closed]

Asked by 7 years ago

This question already has an answer here:

Math.Random doesn't function properly?

Answers on a previous question told me to put math.randomseed(tick()) told me to put that line of code at the very top of my script. My question is do I need it in a function or can I put it at Line One?

math.randomseed(tick())-- does it have to be here
local Maps = game.ServerStorage:WaitForChild("Maps"):GetChildren()

function chooseMap()
    --math.randomseed(tick()) or can it/ does it have to be here
    local randomMap = Maps[math.random(1, #Maps)]:Clone()
    print(randomMap.Name)
end

what if i had a while true do loop like this :

--does math.randomseed(tick()) have to be on the first line
-- code in between and naming functions and stuff before the loop, etc.
while true do
    function chooseMap() -- or can it be in the function
end

basically, my question is where can it go

Line 1. You should only ever execute randomseed once, at the very start of the game.

Putting it in a function would mean you could accidentally invoke it again.


The first several numbers you get after setting a seed typically aren't very high quality.

You should ask for a few numbers that you'll just throw away to prime it:

math.randomseed(tick())
for i = 1, 10 do
    math.random()
end

Alternatively, you can use a more "chaotic" seed like

math.randomseed(tick() % 1 * 1e6)

The issue is that it's still spitting out the same map for him. Perhaps a method of seeing if it was the last chosen map Edenojack 171 — 7y

Chaotic means it adds more possible outcomes like decimals. For your purposes, keep it as whole numbers. Viking359 161 — 7y

tick() only changes by 1 every second. Similar seeds lead to similar initial values out of the random number generator. The alternative changes once every microsecond, so you get a much broader distribution of seeds. BlueTaslem 18071 — 7y

You put it inside the function

    local Maps = game.ServerStorage:WaitForChild("Maps"):GetChildren()
    function chooseMap()
        math.randomseed(tick()) --< RIGHT HERE
        local randomMap = Maps[math.random(1, #Maps)]:Clone()
        print(randomMap.Name)
    end

putting it at the function's first line doesn't work for me, only 1st line of the script works Subaqueously 11 — 7y
