How to fast restart game in multiplayer mode

[dooliu]

Multiple players means multiple processes, so the only way i know is leave game and re-join the game is through controllers, but it will costs 3-4 seconds, which is too slow for reinforcement learning training.
The reset function code are as follows:

def _restart(self): if (len(self._players) == 1 and len(self._players[0].race) == 1 and len(self._maps) == 1): # Need to support restart for fast-restart of mini-games. self._controllers[0].restart() else: if len(self._controllers) > 1: self._parallel.run(c.leave for c in self._controllers) self._create_join()

How to quickly restart? Anybody knows?
