How do I use math.randomseed(tick()) within a function or is that unnecessary? [closed]
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?
1 | math.randomseed(tick())-- does it have to be here |
2 | local Maps = game.ServerStorage:WaitForChild("Maps"):GetChildren() |
3 |
4 | function chooseMap() |
5 | --math.randomseed(tick()) or can it/ does it have to be here |
6 | local randomMap = Maps[math.random(1, #Maps)]:Clone() |
7 | print(randomMap.Name) |
8 | end |
what if i had a while true do loop like this :
1 | --does math.randomseed(tick()) have to be on the first line |
2 | -- code in between and naming functions and stuff before the loop, etc. |
3 | while true do |
4 | function chooseMap() -- or can it be in the function |
5 | 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:
1 | math.randomseed(tick()) |
2 | for i = 1, 10 do |
3 | math.random() |
4 | end |
Alternatively, you can use a more "chaotic" seed like
1 | 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" ? Subaqueously 11 — 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
1 | local Maps = game.ServerStorage:WaitForChild("Maps"):GetChildren() |
2 | function chooseMap() |
3 | math.randomseed(tick()) --< RIGHT HERE |
4 | local randomMap = Maps[math.random(1, #Maps)]:Clone() |
5 | print(randomMap.Name) |
6 | end |

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