I am fairly new to Python programming and Threads isn’t my area of expertise. I have a problem for which i would hope that people here can help me out with.

Task: as a part of my master thesis, i need to make a mixed reality game which involves multiplayer capability. in my game design, each player can set a bunch of traps, each of which is active for a specific time period e.g. 30 secs. In order to maintain a consistent game state across all the players, all the time check needs to be done on the server side, which is implemented in Python.

I decided to start a python thread, everytime a new trap is laid by a player and run a timer on the thread. All this part is fine, but the real problem arises when i need to notify the main thread that the time is up for this particular trap, so that i can communicate the same to the client (android device).

i tried creating a queue and inserting information into the queue when the task is done, but i cant do a queue.join() since it will put the main thread on hold till the task is done and this is not what i need nor is it ideal in my case, since the main thread is constantly communicating with the client and if it is halted, then all the communication with the players will come to a standstill.

I need the secondary thread, which is running a timer, to tell the main thread, as soon as the time runs out that the time has run out and send the ID of the trap, so that i can pass this information to the android client to remove it. How can i achieve this ??

Any other suggestions on how this task can be achieved without starting a gazillion threads, are also welcome.. 🙂 🙂

Thanks in advance for the help..

Cheers

    i have finally found a nice little task scheduler written in python, which actually is quite light and quite handy to schedule events for a later time or date with a callback mechanism, which allows the child thread to pass-back a value to the main thread notifying the main thread of its status and whether the job was successfully done or not.

    people out there, who need a similar functionality as the one in the question and dont want to haggle around with threads can use this scheduler to schedule their events and get a callback when the event is done

    here is the link to APScheduler
