Minecraft Pi downloading and extraction commands via the
LXTerminal on Raspberry Pi
4.
To run Minecraft Pi, type these lines:
cd mcpi
./minecraft-pi
You may remember using the
cd
command in previous adventures to change
directories or folders from the command line. You use it here to move from
/home/pi
into the directory
/home/pi/mcpi
where the
minecraft-pi
game is located. Run the command
./minecraft-pi
to start the game. You'll
see a screen similar to Figure 6-1.
