Hello, I am currently part of a MMORPG project in python, using Twisted and python-ogre. I found some posts talking about the cohabitation between the two. However I couldn't find a definitive answer. What I am seeking for is more a general method than technical details. What I would like to do is to put properly Twisted and python-ogre together. To do that I have already tried the following ways : - First run python-ogre in the main loop. At a time, this loop launches the twisted reactor in another thread with Thread(target = sthg_which_runs_reactor.run). The problem I am experiencing is described here [1]. The sendLine method is executed immediately, but the data is received by the other side only 20/30 seconds after. - So I tried not to run Twisted in another thread, by using the way described here [2]. Twisted is given the main loop and the rendering is done frame by frame with the coiterate. It works sometimes, the renderOneFrame in the coiterration is not really working. But it seems more logical to run ptyhon-ogre in the main loop and twisted on the side (in another thread for example, as soon as the client has decided to connect to the server). Have you any ideas how I could do this properly (with threads, without threads, with the coiterrate ...)? If Twisted was originally made for MMORPGs, why the reactor wants so much to be in the main loop and to manage itself the other threads (with callInThread for example)?
