title: How to show score in game via HTML5 output?
body: <p>So my HTML5 has this output </p>
  
  <pre><code>&lt;output id="counter" value="0" /&gt;
  </code></pre>
  
  <p>Now my Dart has this</p>
  
  <pre><code>for (Gunner gunner in gunners) {
    if (bullet.checkCollision(gunner)) {
      deleteBullets.add(bullet);
      deleteGunners.add(gunner);
      int zero = 0;
      count() {
        zero = zero + 1;
        document.getElementById("counter").innerHtml = zero.toString(); 
      }
      count();
    }
  }
  </code></pre>
  
  <p>So what I am trying to do is every time I kill a gunner I get the counter to go up 1 but after I kill 1 gunner and get 1 point I can't get anymore, it stays at 1 and won't keep counting my kills after the 1st kill.</p>
