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> <nav> <ul> <li><a href="/">Home</a></li> <li><a href="/running">Running</a></li> <li><a href="/history">History</a></li> <li><a href="/thanks">Thanks</a></li> <li><a href="https://github.com/dirtbags/tanks" title="Tanks on Github">Source</a></li> </ul> </nav> </body> </html>
