multithreading love with love.thread

Post by TechnoCat »

Here is a really simple example of love.thread in use. love.thread is a new feature in LOVE 0.7.0.

It just opens up and waits for the user to press space. When he does, a thread starts generating images and sends them as fast as it can process them. Meanwhile, you will always have responsiveness of your circle cursor (depending on your system of course).

main.lua:

Code: Select all


function love.load()
  --create a thread named worker running the code in thread.lua
  thread = love.thread.newThread("worker", "thread.lua")
  --start the thread
  thread:start()
end


function love.update(dt)
  local imageData = thread:receive("progress")
  -- Only run this if it recieved something
  if imageData then
    image = love.graphics.newImage(imageData)
  end
end

function love.draw()
  if image then
    love.graphics.draw(image, 0,0)
  end
  local x,y = love.mouse.getPosition()
  love.graphics.circle("line",x,y,30,48)
end

function love.keypressed(k)
  -- Start the thread when spacebar is pressed
  if k==" " then
    --send the message to start
    thread:send("run", true)
  end
  if k=="q" then
    --send the message to quit
    thread:send("quit", true)
  end
end
thread.lua:

Code: Select all


--You must require the love modules in threads to use them
--require("love.thread") --this module doesn't need to be required
require("love.timer")
require("love.image")

--To perform thread operations, you have to find yourself
local this_thread = love.thread.getThread() --or love._curthread

function generateImage()
  math.randomseed(love.timer.getTime())
  function pixelFunction(x, y, r, g, b, a)
    r = math.random(10) + b + x % 10
    g = math.random(10) + r + y % 10
    b = math.random(10) + a + x*y % 20
    a = math.random(10) + g + x+y % 15
    return math.ceil(r), math.ceil(g), math.ceil(b), math.ceil(a)
  end
  local image = love.image.newImageData(512,512)
  local response = nil
  --The thread will never leave this loop until quit recieves true
  while true do
    image:mapPixel(pixelFunction)
    --send the updated image back to the main process.
    this_thread:send("progress", image)
    if this_thread:receive("quit") then
      --leave the function and finish the thread execution
      return
    end
  end
end

--This waits for the main process to send a signal to start
this_thread:demand("run")
generateImage()
--When this part is reached the thread terminates

Re: multithreading love with love.thread

Post by Jasoco »

Brilliant. Thanks! A few things though..

I must have misunderstood threading because when I opened Activity Monitor, love.app didn't have any extra threads under it like Chrome does where it has all tabs and extensions in its own processes. I guess threads ~= processes?

How many threads does this sample use? And how many can löve do at once?

Also, when I close it, it crashes. Not a blue Löve error, but an OS X "Application has crashed, send report?" error. Maybe the program isn't stopping the threads correctly? It only crashes if I start the threading first.

As the debug said, thread #4 (which may very well be the first one you spawn yourself) crashed in setPixel.

Yeah. I saw that. Anyone know what it means? Is it an error with his code, or with the 0.7.0 beta? Does it crash in every love project that uses threads? And is it every OS or just OS X?

I got same error in OSX 10.6.5. Takes a while to get the error after i quit the app. I guess as Jasoco said Love isn't closing threads in the right way.

Re: multithreading love with love.thread

Post by Jasoco »

For me the error shows up immediately after the window disappears. If it weren't for the error, I wouldn't know it crashed.

I opened it in the Terminal and once again, Bus Error.

As a test, I put my custom love.run() function in and added a Print statement in the event handler. Can't pinpoint when the error happens so it's not the code, rather the threads not being shut down correctly. Maybe if you added a thread stopping code to a love.run() function of your own that would be called when you quit, it would end better instead of crashing. How exactly would you go about stopping any running threads in the middle of their run? Apparently it's not thread:stop().

Try Thread:kill() in love.quit()

Probably this is beyond our scope. This is something that who is porting Love to OSX must for sure fix in macOS package app.
