Why I get this error?

[Blaawee]

      local random = musics[math.random(#musics)] 

[drk]

LOL '-' I will try.

Edit: Don't work. Same error but on the argument 1.

[SDK]

Because you changed the indexes of the table, the table should be formatted this way

local musics = { 
        [1] = { 'David Guetta - Where Dem Girls At', 'http://199.167.195.194/wdga.mp3'}, 
        [2] = { 'Coldplay - Paradise', 'http://199.167.195.194/pd.mp3'}, 
        [3] =  
... 
} 
  
local themusic = musics[math.random(#musics)] 
local file = themusic[2] 
local title = themusic[1]  

[drk]

That [1], [2], [3], ... is index, yee?

[Castillo]

Yes, it is.

[karlis]

#returns length of indexed table only, you may use second indexed table to access random song.

[drk]

Hey, now I get this error on line 103: attemp to index field '?'(a nil value)

line 113:

        currentSound = playSound(theSound, true) 

theSound variable is

        local theSound = sounds[math.random(2, #randoms)] 

When the music will change I get this error and the music started plays again =s

Edit: Oh, and the #randoms table is

    local randoms = { 
        'http://199.167.195.194/wdga.mp3', 
        'http//199.167.195.194/pd.mp3' 
    }

[Castillo]

local theSound = randoms[math.random(#randoms)] 

[drk]

Ah. I've not seen this I will try

Edit: Same error, on line 113.

[Castillo]

Post your whole script.

[drk]

Double click play sound:

              local song = guiGridListGetItemData(source, row, music_grid_column) 
              if isElement(currentSound) then 
                destroyElement(currentSound) 
              end 
              currentSound = playSound(song, true) 
              guiSetText(music_name, tostring(name)) 
            else 
              if not source then 
                setRandomMusic() 
              end 
            end 
        end

setRandomMusic function:

    function setRandomMusic () 
        local theSound = randoms[math.random(#randoms)] 
        currentSound = playSound(theSound, true) 
        setTimer(currentSound, 1000, 1) 
        guiSetText(music_name, tostring(name)) 
    end 

It's not the full code, only a part.

[Castillo]

Works perfect..

function setRandomMusic () 
    local theSound = randoms[math.random(#randoms)] 
    currentSound = playSound(theSound, true) 
    guiSetText(music_name, tostring(name)) 
end 

I removed that timer because it was useless and wrong used.

[drk]

LOL Here not works...

Edit: But I have to create a timer to when the random music end's starts another, right? And you know why I get the error 'attemp to index field '?'' ??

[Castillo]

I get no error here, maybe is another line?

[drk]

Line 113: currentSound = playSound(theSound, true)

In debugscript appears this line...

[Castillo]

Post your WHOLE script, and I mean EVERYTHING.

[drk]

I will give the code by PM.

[Castillo]

Works perfectly, I even executed setRandomMusic() alone and it also works fine.

[drk]

Try selecting a music on the gridlist, wait for the end and see debugscript

[Castillo]

First, the sound will never stop because you set it to loop, second, live streams doesn't has length, so you can't really know when it's over.

And third, the script doesn't output any error.

[drk]

But if live streams don't have length how TG owner has made the random music for the radio of the server clan? '-'

[Castillo]

Wiki quote:

length: The length of the stream in milliseconds. Always returns 0 for a live stream

[FatalTerror]

I think he create a new event when the sound is stopped, and if it's stopped he set another song
