Grab user input asynchronously and pass to an Event loop in python -

i building single player mud, text-based combat game. not networked.

i don't understand how gather user commands , pass them event loop asynchronously. player needs able enter commands @ time game events firing. pausing process using raw_input won't work. think need select.select , use threads.

in example below, have mockup function of userinputlistener() receive commands, , append them command que if there input.

if have event loop such as:

from threading import timer import time  #main game loop, runs , outputs continuously def gameloop(tickrate):      #asynchronously user input , add command que      commandque.append(userinputlistener())     curcommand = commandque(0)     commandque.pop(0)      #evaluate input of current command regular expressions     if re.match('move *', curcommand):         moveplayer(curcommand)     elif re.match('attack *', curcommand):         attackmonster(curcommand)     elif re.match('quit', curcommand):         rungame.stop()     #... etc          #run various game functions...     dostuff()      #all done loop, sleep     time.sleep(tickrate)  #thread runs game loop rungame = timer(0.1, gameloop(1)) rungame.start() 

how user input in there?

or more simply, can show me example of storing user input while loop running @ same time? can figure out rest if can far.

you indeed need 2 threads. 1 concerned main game loop , 1 handle user input. 2 communicating through queue.

you can have main process start game loop thread , have obtaining line of text user , "puting" queue (i.e following rungame.start()). can simple as:

while not gamefinished:     myqueue.put(raw_input()).  

the game loop thread "geting" line of text queue, interpert , execute it.

python has thread-safe queue implementation can use (including basic example multi-threaded usage can use guide).

there's simple command line interperter module (the cmd module , here practical overview) might useful kind of project.
