AUTHORDASHED!
By Andrew Bennett
Introduction
I FIRST came across BOULDERDASH on the ZX-Spectrum. It was written by a
person called Peter Liepa and it left me totally awestruck. When I owned
an Acorn Electron, the poor man's BBC, I decided to start work on
writing an "improved" version of the game. After learning how to write
in assembler - which took me about a week - I came up with hundreds of
additional features and, after about three months, I had a pretty fast
and smooth version to play around with.
Although this version didn't ever see daylight professionally, some
of these ideas were:
Conveyor blocks - these moved whatever was sitting on them left or
right (if the object was moveable). They were also moveable themselves
so that if you dropped a heap of conveyor blocks they would initially
form a heap (like boulders) but then would start transporting themselves
sideways, eventually forming one long flat conveyor belt.
Bombs - these moved just like boulders but, if struck by or falling
into something hard, started a countdown and then explosion. Any other
bombs caught in the blast would themselves also start to countdown so
cute chain reactions were possible.
Eggs - these were of the same sort of logic as the bomb but looked
like an egg (obviously) and instead of exploding hatched into fireflies/
butterflies.
Rockets - these were excellent features but very difficult to des-
cribe; they would only ignite if the space in front of them was empty.
Once ignited they would move through earth, slime, etc (and bounce off
boulders) until they either hit a wall or were trapped in a cul-de-sac
(and were only able to reverse).
Grabbers - these were kind of remote control grabbing devices that
you moved by keeping the fire button pressed. They would automatically
pick up boulders - and almost anything else - and release it when the
fire button was let go of.
Transporters/Replicators - these were weird kinds of device consist-
ing of one or more inputs and one or more outputs. In 1 input/1 output
mode, anything above the input block would disappear and reappear above
the output block. But if more than one output block existed, this would
mean copies of the object would be made. And if, for example, one of the
output blocks was positioned so that a boulder come come out of the out-
put and fall back into the input end, it would give rise to a permanent
stream of boulders!
There were a few more things I tried but I've forgotten half of them.
How I Got To Write The Original
ABOUT the time I had a perfectly good game engine, I heard that Tynesoft
were in the process of doing conversions of First Star games for the
BBC and Electron. So I headed down to the Olympia Computer Show and
showed them a videotape of my game. Although I didn't bother to show off
all my ideas, they seemed impressed and said they would be in touch...
After a few days, I got a phone call saying that they wanted to pub-
lish a version of the original BOULDERDASH and, using my engine, they
considered I, with the game's core already created, should be able to
turn it into a simple copy of the original quite straight-forwardly.
I agreed but in fact it took over three months, meaning that I missed
a Christmas release date. The reason was simple: I simply couldn't
figure out what pseudo-random method Peter Liepa had used to generate
much of the background patterns (random sprinkling of boulders, spaces,
etc) in each cave. Tynesoft said they would try to get the information
for me but never did. Eventually I had to painstakingly go through every
cave on the game (using a copy of the original for the MSX), copy down
the map for each level then find some way of squeezing the 100+ levels
into the memory available. On the standard BBC there was only 32K total
memory; 10K of which was needed for the screen.
Anyway, eventually I finished this exhausting task (January 1987) and
took the disk up to Newcastle. We signed a contract which gave me an
advance of `400 and a royalty of 65p per game sold (at `9.95 a copy!).
The game got pretty good reviews in the mags [Gaining the "Golden Game"
award in ELECTRON USER Vol 5 No 7 - Ed] and it was a nice feeling walk-
ing into WHSmith and seeing copies of 'my' game on the shelves.
Despite this, I don't believe it sold that well. The old 8-bit com-
puters were going out of fashion with the arrival of the ST and Amiga
plust the BBC/Electron share of the market was pretty tiny in the first
place. I don't have any real idea of how many copies sold though. Tyne-
soft never bothered sending any royalties, or even information, and
after a few phonecalls I gave up trying to get them to pay up.
The experience put me off the idea of coding for a long time as I'd
hoped the royalties would help me with the costs of going back to uni to
study Physics.
A Few More Thoughts
I BELIEVE that the appeal of BOULDERDASH lies in its 'physics'. It's
fascinating to see how fairly simple local rules can give rise to sur-
prisingly complex global behaviour; essentially it's a universe of fair-
ly simple cellular automata, albeit that one of the objects takes its
actions from the player.
This is what I think is crucial to a good game - the so-called 'play-
ability' of game is related to the simplicity of its rules and the
complexity of the consequences of those rules.
Even after I'd been writing and testing it for six months, I still
found I could waste hours at a time just setting up weird scenarios and
seeing what happened. I only got tired of the game during the tedious
business of entering, compressing and testing each cave.
My Version
THE incredibly optimised main code took up only 6K! And the data (caves,
etc) took up 13K. Oh, if anyone still has a copy (Original or pirate -
no sweat with either as it's not as if I got any royalties anyway!), try
pressing <B> on the title screen for a secret credits list!
IN closing, Peter Liepa, wherever he is, is an utter genius; I hope he
made a fortune!
