title: Ask turtle to turn face other target depending on patch features
body: <p>I'm stuck at this part of my code.</p>
  
  <ul>
  <li>I want to move my turtle under my control. I mean when it first reached a house, it must turn and move to another house.</li>
  </ul>
  
  <p>In this code, it will move -10 5 which red patch and house shape here.
  Now, <strong>how can I tell this turtle ''you are here and you must go there''</strong> !?</p>
  
  <p><em>(I use a red patch because I tried to move the turtle depending on patch but can't find any solution.)</em></p>
  
  <pre><code>breed [cities city]
  breed [flag person]
  
  to setup
      clear-all
      set-default-shape cities "house"
  
      create-flag 1
      [ set SIZE 6 set shape "by" setxy -5 3 set HEADING 0 ]
  
      create-flag 1
      [ set SIZE 6 set shape "sel" setxy 12 5 set HEADING 0 ]
  
      create-cities 1
      [set color yellow set SIZE 2 setxy 8 2]
  
      create-cities 1
      [ set color yellow set SIZE 2 setxy -10 5]
  
      ask patch -10 5 [set pcolor red]
  end
  
  to go
      ask flag with [ shape = "by" ] [ facexy -10 5 forward 1 set HEADING 0 ]
  end
  </code></pre>

  <h2>Update</h2>
  
  <p>I understand and tried this code from @jenB's answer and it's yet not moving as I want. Thank you for your interest, but there are two problems here that I tried to explain with this picture.</p>
