• Game engine with python scripting?

  - by Kayle

  Looking to put together a 3D side-scrolling action platformer. Since this is my first time trying to put together a non-simple adventure game, I'm at a loss for which engine to consider. I would prefer one that supports scripting in python, since that's my primary language. Without tight controls, the game will suck... so speed is a priority. Cross-platform is also important to me. Any suggestions?

• python subprocess block

  - by MW

  Hello. I'm having a problem with the module subprocess. I'm running a script from python through: subprocess.Popen('./run_pythia.sh',shell=True).communicate() and sometimes it just blocks and it doesn't finish to execute the script. Before I was using .wait() instead of .communicate() but then because of this: http://dcreager.net/2009/08/06/subprocess-communicate-drawbacks/ I changed to .communicate(). Nevertheless the problem continues. Can anyone help me?
