Repeat music

Hi!

This is a simple program i made to infinitely repeat music from a disk drive. It can detect when the disc is removed so to stop music, just take the disc out. I have not tested this on every single music disc, so the time until the song starts over may vary. Will adjust if needed.

Install:
1. Go to "%appdata%/.minecraft/mods/ComputerCraft/lua/programs"
2. Create a new file called "repeat" without any extensions
3. Open that file in Notepad or some other text editor
4. Copy-Paste the code to that file
5. Save and quit

Usage:
Just type in "repeat <side of disk drive>" to the computer console.

lengths = {["C418 - 13"]=180, ["C418 - cat"]=186, ["C418 - blocks"]=347, ["C418 - chirp"]=186, ["C418 - far"]=172, ["C418 - mall"]=197, ["C418 - mellohi"]=98, ["C418 - stal"]=151, ["C418 - strad"]=191, ["C418 - ward"]=250, ["C418 - 11"]=70}
args = { ... }
if #args == 0 then
print("Usage: repeat <side>")
return
end
command = args[1]
if disk.isPresent(command) then
if disk.hasAudio(command) then
  while disk.isPresent(command) do
   print("Playing ".. disk.getLabel(command))
   disk.playAudio(command)
  
   timesSlept = 0
   length = lengths[disk.getLabel(command)]
   while timesSlept <= length do
    if disk.isPresent(command) == false then
  print("Disk removed")
  return
end
    sleep(1)
timesSlept = timesSlept + 1
   end
  end
else
  print("Disk in ".. command .. " drive is not an audio disk")
end
else
print("No disk in ".. command .. " drive")
end

Please give feedback and suggestions if you want to.

It would be better to use a timer and the "disk_eject" event instead of the sleep and disk.isPresent:

print("Playing ", disk.getLabel(command))
local lenght = lenghts[disk.getLabel(command)]
local timer = os.startTimer(lenght)
while true do
  local evt, arg = os.pullEvent()
  if evt == "disk_ejected" then
    if arg == command then
	  break
    end
  elseif evt == "timer" then
    if arg == timer then
	  disk.playAudio(command)
	  timer = os.startTimer(lenght)
    end
  end
end

It would wait for the disk to be ejected/removed or until time ends instead of checking every second.

Cool, i didnt know about that. :)/>/>

I absolutely love this program, but I have one question. I have the Portal music, from the Portal Gun Mod, and I was wondering how you timed the music discs. Was it in seconds or ticks?

Great job, it must have been a nightmare to get all that timing right.

Looking at the code, it would be seconds.

How did you time the disks? Did you some sort of CC program, or just did you just use a stopwatch?
