We're looking to include a new, often-requested feature in the Project Sentry Gun code, which will allow users to control the sentry with a USB joystick or game controller while in manual mode.
Before I can release this feature in a full code version, I'm looking for some users to test the basic functionality with their own input devices (game controllers, joysticks, or whatever else you want to use). You can download the beta version here: https://sites.google.com/site/projectsentrygun/downloads/InputDeviceSetup_Beta.zip?attredirects=0&d=1 and try it out for yourself.
Please let me know if you have any trouble. I want to make sure this works with a wide variety of input devices.
