Values getting removed then coming back?

Asked by 8 years ago

When I try removing the ChosenSong and FakeChosenSong values they print as nil but are used multiple times and they print at the bottom normally. So they don't actually get removed and im not sure what is causing this.

songs = {461736208,438917260,516046263,506212392}

boards = workspace.Boards

while true do

    chosensong = songs[math.random(1,#songs)] --Choses a random ID from songs list
    chosenboard = math.random(1,4) --Selects random board
    for i = 1,4 do
        if i == chosenboard then
            local songname = game:GetService("MarketplaceService"):GetProductInfo(chosensong) --Gets the asset name from ID
            boards:FindFirstChild("Board"..i):WaitForChild("SurfaceGui"):WaitForChild("SongChoice").Text = tostring(songname.Name) --Places chosen song on boards
            table.remove(songs, chosensong)
            print(songs[chosensong])
        else
            local chosenfakesong = math.random(1,#songs)
            local chosenfakesong = songs[chosenfakesong]
            local songname = game:GetService("MarketplaceService"):GetProductInfo(chosenfakesong) --Gets the asset name from ID
            boards:FindFirstChild("Board"..i):WaitForChild("SurfaceGui"):WaitForChild("SongChoice").Text = tostring(songname.Name) --Places chosen song on boards
            table.remove(songs, chosenfakesong)
            print(songs[chosenfakesong])
        end
    end
    wait(1)
    for i = 1,#songs do
        print(songs[i])
    end
    wait(1)
end

Ok, so, lets start with Line 7

chosensong = songs[math.random(1,#songs)]

This is giving you the number ID for the game to identify/play, not the index number of it. I advise you do something along the lines of

chosensongno = math.random(1,#songs)
chosensong = songs[chosensongno]

Next part is Line 13

table.remove(songs, chosensong)

This is trying to remove a value from the table which does not exist, this is where you would use the value 'chosensongno' making it

table.remove(songs, chosensongno)

You would need to repeat this same process for the fake songs aswell, hope this helps.

table.remove(table,position) removes whatever item is at the position. Therefore, table.remove(table,object) will not work.

Example:

local songs = {1000,2000,3000}
table.remove(songs,3) --Removes 3000 from the table.
table.remove(songs,2000) --This will NOT remove 2000 from the table, since it tries to remove the 2000th item in the table, not the number 2000.
print(songs[1]) --Prints 1000.
print(songs[2]) --Prints 2000.
