Trying to string names together in a parameter but I can't figure it out? I accept answers!

Alright, if you dont know, any string array can have as many strings in it as you want, as long as you specify which number it is. for example, you cannot put in a string = the string array because it doesnt work that way, you have to specify which string in the string array you want to ad or change, like stringarray[2] or the next one after that is stringarray[3], the lowest is 0, so you may be wondering "how do i insert player names into different string arrays" well fun quick story, when i was new to scripting, i used math.random but that was stupid and the sloppiest idea ever, anyway, to do this, change the number everytime and be PREDICTABLE WHILE YOU DO IT, math .random isnt predictable and two numbers could be the same,

the quick answer? Just increment a value everytime a player is added so the numebr is always different and is 1 higher than the last. so your code should be like this (i added a value called num):

local object = script.Parent
local fireObject = game.ReplicatedStorage.speedFire
local player = workspace
local allowedPlayers = ("M9F", "") ---- this is what I need help with
local debounce = false
local num = 0

local function giveSpeed(hit)
    if debounce == false then
        debounce = true
        if hit.Parent:FindFirstChild("Humanoid")then
            if hit.Parent.Name == allowedPlayers[num] then
num += 1 --adds 1 , same as num = num + 1
                hit.Parent.Humanoid.WalkSpeed = 50
                hit.Parent.Humanoid.JumpPower = 75
                if not hit.Parent.Head:FindFirstChild("speedFire")then
                    local clonedFire = fireObject:Clone()
                    clonedFire.Parent = hit.Parent.Head
                end
            end
        end
        debounce = false
    end
end
object.Touched:Connect(giveSpeed)

hope this helps :3

oh hold on i jsut realised i misunderstood the qustion, ok i understand now, lemme answer it correctly this time heheh sorry.

So your trying to test all of the player names in the string array to see if they math the player being tested. simple, make a pairs loop like this.

failures = 0

for _,i in pairs(allowedPlayers) do

    if not i == hit.Parent.Name then--so this means if the player name does NOT match whats in the string being testing in the string array

        failures += 1 --adds one

    end

end

--any code after the loop will run when the loop finished, which means this code below will run once all strings in the array are tested

if failures == #allowedPlayers then--# means number or amount, so #allowedPlayers means the amount of strings in that array, so if all the strigns failed, then below code with execute

--code you want

end
