<p>Handy function for "killing" game objects. Use <code>reset()</code> to revive them.
Default behavior is to flag them as nonexistent AND dead.
However, if you want the "corpse" to remain in the game, like to animate an effect or whatever,
you should <code>override</code> this, setting only <code>alive</code> to <code><a href="../Bool.html">false</a></code>, and leaving <code>exists</code> <code><a href="../Bool.html">true</a></code>.</p></div></div><div class="field "><a name="revive"></a><h3 class="ancho
