[Lua][Question] Parallel Help?

I have a program that uses a parallel to download a file while a loading bar is being shown. The thing is, the loading bar is taking priority over the download and the file won't download until the loading bar stops. The thing is, the download function tells the loading bar when to stop, so until the download finishes, the loading bar will keep going until the download starts, which won't because of the loading bar. Please help! Here is the code (I have the download function set to wait 5 seconds because I will have more then one file.) The loading bar ISN'T one of those annoying loading bars that are fake. It waits for the download to finish. Just an FYI. Also, this code is ALL me. No help at all.

I am not sure of this, but I think because you use "shell.run()" to download the file, it will run that program, which overwrites anything else that happens in the code. I got a thing you could do IF what I am saying is correct (I will need a real pro to confirm that though :P/>).

- Write your own pastebin function using the http://pastebin.com/raw.php?i= API provided by pastebin itself. (You can probably find this somewhere around here)
- Copy the pastebin API and use it as a local function

Again, I am not familiar with this, so if I were you I would wait for other replies that may be more usefull, just thought I would post it anyway, maybe its usefull anyways :P/>

Thanks, but that doesn't work. I am starting to experiment with GitHub and it is giving me troubles too.

Ignore Woody's advice above. Change `load(9)` to `function() load(9) end` in your parallel call. It's waiting for the load function to return before it starts the paralleling.

I'm not sure if I did this right. I put parallel.waitForAny(downloadFiles, function() load(9) end) and it gives me a "parallel: 4: bad argument: function expected, got boolean" error. Help?

I updated my code if this helps

never mind I will just stick with pastebin. Thank you!

See, you caused exactly the same problem again. You can't call either of the functions when you pass them as arguments to parallel. You were calling the downloadFiles function rather than passing it in. You changed more than I told you to, which caused it to not work. If you're told to change something, change only that thing.

function downloadAllFiles()
  downloadFiles("https://raw.github.com/redstonefreak589/redos/master/RedOS","RedOS")
end

function loadNine()
  load(9)
end


parallel.waitForAny(downloadAllFiles, loadNine)

Try that

WTF MY KEYBOARD IS MESSED UP!

Okay, I see what you're getting at. I see now that if I want to do the downloadFiles function along with the load function I need to pass it as a function. Thanks for the constructive criticism Lyqyd!

Okay, so I did end up using my github code, and I was able to fix the parallel with your help, Lyqyd. Thank you for helping me and fixing my mistake and giving me just a push with the construction criticism.
