I use VNC viewer to connect my Pi 3, laptop and Kuman 7" touchscreen, because I cannot get access to a keyboard or mouse. When I open minecraft-pi it shows just a black screen on my laptop, but it loads on my pi screen, and I can click in and play (only the mouse works, the keyboard doesn't). How do I make my laptop's keyboard work with minecraft-pi if it works usually in other circumstances such as editing code, and how can I make it show up on my laptop?
I'm assuming your using RealVNC on the Pi. You need to turn on the 'experimental direct capture mode'.
To turn this feature on, open the VNC Server dialog, navigate to Menu - Options - Troubleshooting, and select 'Enable experimental direct capture mode'
