<p>This is a port of the “Tanks” program written by Paul Ferrell
|
||||
<a href="mailto:pflarr@clanspum.net">pflarr@clanspum.net</a> in 2009-2010. Paul created the entire game based
|
||||
off a brief description I provided him of
|
||||
<a href="http://tpoindex.github.io/crobots">Crobots</a>
|
||||
and a vague desire to
|
||||
“make something fun for high school kids to learn some programming.” We
|
||||
ran Paul’s Tanks as part of a 100-attendee computer security contest in
|
||||
February of 2010 and by all accounts it was a huge success. It even
|
||||
made the nightly news.</p>
|
||||
|
||||
<p>Paul’s version was written in Python and provided a custom language
|
||||
called “Bullet”, which looked like this:</p>
|
||||
|
||||
<div class="highlighter-rouge"><pre class="highlight"><code>>addsensor(50, 0, 5, 1); # 0
|
||||
>addsensor(100, 90, 150, 1); # 1
|
||||
>addsensor(100, 270, 150, 1); # 2
|
||||
>addsensor(100, 0, 359, 0); # 3
|
||||
|
||||
# Default movement if nothing is detected
|
||||
: move(70, 70) . turretccw();
|
||||
random(2, 3): move(40, 70) . turretccw();
|
||||
random(1, 3): move(70, 40) . turretccw();
|
||||
|
||||
# We found something!!
|
||||
sense(3): move(0, 0);
|
||||
sense(1): turretcw();
|
||||
sense(2): turretccw();
|
||||
sense(0): fire();
|
||||
</code></pre>

<p>Nick Moffitt played with this original version and convinced me (Neale)
|
||||
that something like Forth would be a better language. I added some code
|
||||
to accept a scaled-down version of PostScript. The IRC channel we
|
||||
frequent collectively agreed to give this new language the derisive name
|
||||
“Forf”, which should ideally be followed by punching someone after it is
|
||||
spoken aloud. I wrote a Python implementation of Forf, which was slow,
|
||||
and then Adam Glasgall wrote a C implementation, which was quick.</p>
|
||||
|
||||
<p>I decided to take Tanks to Def Con in July 2010, and just for bragging
|
||||
rights, to have it run on an Asus WL-500gU. This is a $50 device with a
|
||||
240 MHz MIPS CPU, 16MB RAM, and a 4MB flash disk, along with an
|
||||
802.11b/g radio, 4-port 10/100 switch, and an additional 10/100 “uplink”
|
||||
port; it’s sold as a home wireless router. I had originally intended to
|
||||
run it off a lantern battery just for fun, but eventually thought better
|
||||
of it: doing so would be wasteful for no good reason.</p>
|
||||
|
||||
<p>Aaron McPhall <a href="mailto:amcphall@mcphall.org">amcphall@mcphall.org</a>, my summer intern at the time, got
|
||||
OpenWRT and Python onto the box and benchmarked it at about 60 seconds
|
||||
for a 16-tank game, after he had profiled the code and optimized a lot
|
||||
of the math. That wasn’t bad, it meant we could run a reasonably-sized
|
||||
game at one turn per minute, which we knew from past experience was
|
||||
about the right rate. But it required a USB thumb drive to hold Python,
|
||||
and when we used the Python Forf implementation, the run-time shot up to
|
||||
several minutes. I began this C port while Adam Glasgall, another fool
|
||||
on the previously-mentioned IRC channel, started work on a C version of
|
||||
a Forf interpreter.</p>
|
||||
|
||||
<p>This C version with Forf runs about 6 times faster than the Python
|
||||
version with Bullet, on the WL-500gU. A 1GHz Intel Atom runs a 16-tank
|
||||
game in about 0.2 seconds.</p>
|
||||
|
||||
<h2 id="whats-so-great-about-forf">What’s so great about Forf?</h2>
|
||||
|
||||
<p>Nothing’s great about Forf. It’s a crummy language that only does
|
||||
integer math. For this application it’s a good choice, for the
|
||||
following reasons:</p>
|
||||
|
||||
<ul>
|
||||
<li>No library dependencies, not even malloc</li>
|
||||
<li>Runs in fixed size memory</li>
|
||||
<li>Not Turing-complete, I think (impossible to make endless loops)</li>
|
||||
<li>Lends itself to genetic algorithms</li>

<p>Dirtbags Tanks is a game in which you pit your coding abilities
|
||||
against other hackers. You write a program for your tank, set it out
|
||||
on the battlefield, and watch how your program fares against tanks
|
||||
written by other players. Dirtbags Tanks is frequently a component of
|
||||
<a href="/ctf/">Dirtbags Capture The Flag</a>.</p>
|
||||
|
||||
<p>Each tank has a turret-mounted laser, two treads, up to ten sensors,
|
||||
and a diagnostic LED. Sensors are used to detect when other tanks are
|
||||
inside a given arc. In the examples on this page, “triggered” sensors
|
||||
turn black. Most tanks will take some action if a sensor is
|
||||
triggered, such as changing speed of the treads, turning the turret,
|
||||
or firing.</p>
|
||||
|
||||
<p>Tanks are programmed in Forf, a stack-based language similar to
|
||||
PostScript.</p>

<h1 id="title">Running Tanks</h1>
|
||||
|
||||
<p>Unfortunately, it’s kind of a mess right now.
|
||||
I know there are a few forks of this code,
|
||||
and I would love it if someone proposed a merge to clearly illustrate how to run tanks.</p>
|
||||
|
||||
<p>When I spin up a new tanks game,
|
||||
typically I run something like:</p>
|
||||
|
||||
<div class="highlighter-rouge"><pre class="highlight"><code>while sleep 60; do ./round.sh */; done
|
||||
</code></pre>
|
||||
</div>
|
||||
|
||||
<p>This assumes all your tanks directories are in the same place as <code class="highlighter-rouge">round.sh</code>.</p>
|
||||
|
||||
<h2 id="included-programs">Included programs</h2>
|
||||
|
||||
<p>I tried to stick with the Unix philosophy of one program per task. I
|
||||
also tried to avoid doing any string processing in C. The result is a
|
||||
hodgepodge of C, Bourne shell, and awk, but at least each piece is
|
||||
fairly simple to audit.</p>
|
||||
|
||||
<h3 id="roundsh-tank1-tank2-">round.sh tank1 tank2 …</h3>
|
||||
|
||||
<p>Runs a single round, awards points with rank.awk, and creates a new
|
||||
summary.html with summary.awk. This is the main interface that you want
|
||||
to run from cron or whatever.</p>
|
||||
|
||||
<h3 id="forftanks-tank1-tank2-">forftanks tank1 tank2 …</h3>
|
||||
|
||||
<p>A program to run a round of tanks and output a JSON description of the
|
||||
game. This is what tanks.js uses to render a game graphically.
|
||||
The object printed contains:</p>
|
||||
|
||||
<div class="highlighter-rouge"><pre class="highlight"><code>[[game-width, game-height],
|
||||
[[tank1-color,
|
||||
[[sensor1range, sensor1angle, sensor1width, sensor1turret],
|
||||
...]],
|
||||
...],
|
||||
[[
|
||||
[tank1x, tank1y, tank1angle, tank1sensangle,
|
||||
tank1flags, tank1sensors],
|
||||
...],
|
||||
...]]
|
||||
</code></pre>
|
||||
</div>
|
||||
|
||||
<p>If file descriptor 3 is open for writes, it also outputs the results of
|
||||
the round to fd3.</p>
|
||||
|
||||
<h3 id="rankawk">rank.awk</h3>
|
||||
|
||||
<p>Processes the fd3 output of forftanks to award points and output an
|
||||
HTML results table.</p>
|
||||
|
||||
<h3 id="summaryawk-tank1-tank2">summary.awk tank1 tank2</h3>
|
||||
|
||||
<p>Creates summary.html, linking to all rounds and showing overall
|
||||
standing.</p>
|
||||
|
||||
<h3 id="designercgi">designer.cgi</h3>
|
||||
|
||||
<p>Accepts form input and writes a tank.</p>
