Lua create function shuffle(numbers)

[beenii]

Hello I think that interesting systems could be created with a function like this
I need it for a system to change townid of my players

the truth is, I don't know how to store data in tables, to create this function

the idea of the function is the following:

be able to use the function: shuffle(numbers) and place the numbers that we need to shuffle for example:

run shuffle(1,2,3,4,5)

and to be able to individually consult the order of each number

result:
shuffle.[1]=5
shuffle.[2]=2
shuffle.[3]=1
shuffle.[4]=3
shuffle.[5]=4

use again shuffle(1,2,3,4,5,6) now with another extra number
shuffle.[1]=2
shuffle.[2]=4
shuffle.[3]=6
shuffle.[4]=5
shuffle.[5]=1
shuffle.[6]=3

obtaining the numbers in a different order, and this order is preserved until we execute the function shuffle again


It does not matter if we store the order in global storage or in mysql, or in the same script, it would help me anyway, I hope can help me

You can just learn how to do it. There is no sense for making your function in tfs repo because it's senseless. You can change townid by executing simple sql query without any external shuffle

It is a function in Lua you do not have to change anything from the repository

This is pretty easy to do tho?

Idk why you'd need a dedicated function for it, but here you go.

function

function shuffle(array)
    local shuffledArray = {}
    while #array > 0 do
        local rand = math.random(#array)
        table.insert(shuffledArray, array[rand])
        table.remove(array, rand)
    end
    return shuffledArray
end

Usage

local shuffle = shuffle({1,2,3,4,5,6,7,8,9})
for i = 1, #shuffle do
    print(shuffle[i])
end

local shuffle = shuffle({"dog","cat","elephant","wolf","whale"})
for i = 1, #shuffle do
    print(shuffle[i])
end

    print(shuffle[i])
end

local shuffle = shuffle({"dog","cat","elephant","wolf","whale"})
for i = 1, #shuffle do
    print(shuffle[i])
end

It works perfectly

a question, when i run

local shuffle = shuffle({1,2,3,4,5,6,7,8,9})
for i = 1, #shuffle do
    print(shuffle[i])
end

To check the order after executing, i need to store them in a global storage right?

The reason why I needed this function I am making a war system where I have map change every hours, and I want the map to be random, but not repeat the same map.

You can store them in a global table, the caveat being that the table will be destroyed upon server reset.
If you need the information to persist between server saves, then yeah, globalstorage, or a text document.

can you teach me how to store in a global table?
it doesn't matter that it gets destroyed when the server restarts

I'll have to show you over discord I think.
It's dependent on your tfs & script.
