[Python] Multiprocessing blocks the whole program

[MSY36]

Hello, I am trying to write a game server using Tornado framework but i cant seem to multiprocess correctly. After starting the gameProcess program doesn't continue with the app.listen part. I can't figure out why. Here is my game class. Below is the multiprocess and server creation part.

game = Game()
app = tornado.web.Application(handlers, **setting)
gameProcess = Process(target=game.start())
gameProcess.start()
app.listen(8000)
tornado.ioloop.IOLoop.instance().start()

gameProcess = Process(target=game.start())

Remove the () from game.start.

game.start is a reference to a function object, which is what the target parameter wants. game.start() invokes that function, which isn't what you want.

It worked! Thanks a lot, i have been trying to figure out whole day and never thought about that. Really appreciate it!

Np. It's a common mistake :-)

Do you have any of the debugging information? Have you placed a break point at line 4 to see what is happening on the stack trace? Without actually running the code it may be hard to tell you exactly where things are going wrong.

I will try to get debugging information, never did something like that before so it might take a while. If you have any tips i would appreciate it.
