Have you dug yourself into a minecraft black screen? Go to the options menu by pausing the game with the Esc key. From there, click video settings and increase the brightness until you can tell which direction is up.
I’ve been playing minecraft to understand what my nephews like about it. The biggest problem is I keep getting stuck in the dark (in a pitch black hole). Either I dig straight down, or night comes, or I fall into a lake.
The key to getting out was to go to the options menu and turn up the brightness.
I’m playing using the Mac desktop version of the game. Other articles I found told me to dig stairs to get out, but I couldn’t even see which way was up or down.
Apparently there used to be some kind of /home or /kill command but they don’t work for me in the current version. The only solution when I find myself in a black hole is to increase the brightness of the screen and dig stairs (in an upwards diagonal direction) to climb out.
