NETLOGO: How do I make a turtle die if there are two turtles on one patch?
<p>What I'm trying to figure out is how to make one turtle die when there are two turtles on any one patch.</p>

<p>This is what I've been attempting so far:</p>

<pre><code>to deathbytubes
  if ask patches [show count turtles-here] &gt;= 2
  [die]
end
</code></pre>

<p>How can I fix this so that it works?</p>

<p>Also, can anyone help me figure out how to make turtle die when it comes into contact with another turtle as an alternative?</p>
