Not Removing From Table Correctly?

Asked by

ok so my issue is im finding the highest number in my table and that is working fine but once the script iterates again the old values are still there obviously, so i have to delete them but for some reason i cant figure out how and i have tried 2 methods the first was using table.remove and the second was deleting key by key

Script:

local Screens = script.Parent.MapVotingScreens:GetChildren()
local AlsoScreens = script.Parent.MapVotingScreens:GetDescendants()
local highest = 0
local nums = {}

while wait(.5) do
    for x,y in pairs(Screens) do
        local Votes = y.Votes
        table.insert(nums,Votes.Value)
        for i,v in pairs(nums)do
            if v > highest then
                highest = v
                for k,d in pairs(AlsoScreens) do
                    if d:IsA("SelectionBox") then
                        d.Visible = false
                    end
                end
                y.SelectionBox.Visible = true
            end
        end
        nums[x] = nil --table.remove(nums,x)
    end
end

Try using a for loop for every value inside of the nums table and remove each one like that? Or couldn't you just set nums back to {}? killerbrenden 1537 — 4y

There's 1 way I thought of doing this as well.

1) Find the position of each value in the table and remove it.

Method 1

local nums = {}

for _,val in pairs(nums) do
    local posVal = table.find(nums,val)
    wait(0.1)
    table.remove(nums,val)
end

This will iterate through the table and find the position of each value in the table and remove it.

I'm pretty sure both of these works. But, if this helped don't forget to select this as the answer!

So, the values are not being added to the table? I'm assuming as it says 0 before? killerbrenden 1537 — 4y
