ost of
The MagPi
team were raised with arcade games of one
kind or another. So when we heard about Martin Kauss’s
Pi‑powered pinball machine (page 30), we had to know more.
A lucky few remember the golden age of Williams vs. Bally/Midway,
EDITOR
but even if you’ve never played pinball, there’s a lot to learn from
building a ball basher.
Younger fans will be more stunned by Steam Link (page 38). With
this software installed, you can stream the very latest PC games on
a Raspberry Pi.
With Steam Link, a Raspberry Pi computer becomes an amazing
alternative to the latest consoles. It’s especially incredible when you
remember these games are running on a machine costing just $35.
Fun though all of this is, it’s far more rewarding to make your own
games. We’ve been looking at coding classics such as Space Invaders,
Pong, and Pac‑Man recently. Now it’s time to build your own game
from the ground up: Mark Vanstone starts his tutorials on coding a 3D
isometric adventure game (page 42).
We learn by building. And
whatever your favourite flavour of
arcade game, you’ll find something
special to build this month.
