I am in the process of making a multiplayer game in PsychoPy. It’s going well. I have assigned unique keys to each player. The computer running the task will have two keyboards connected to it. I wanted to ensure that player 1 could not accidentally press (and submit) unique keys for player 2. I’ve looked deep into the code, and found that under ioHubKeyboardDevice, it says "Only one keyboard device is supported in an experiment at this time … ".
Is this still the case? I guess at the end of the day I just need unique keys and inputs (i.e., unique keyboards) for each player.
