title: OnTriggerEnter2D(Collider2D col) doesn't seem to be working
body: <p>I've tried making this little thing where if the player clicks it shoots, but it doesn't seem to be working. Here is the code:</p>
  <pre><code>void OnTriggerEnter2D(Collider2D col)
  {
      if (col.gameObject.tag != &quot;player&quot; || col.gameObject.tag != &quot;fireball&quot;)
      {
          Debug.Log(col.gameObject.tag);
          Destroy(gameObject);
      }
  }
  </code></pre>
  <p>This code is meant to be if the col isn't equal to player or fireball it destroys the gameObject and debugs the <code>col</code>'s tag.</p>
  <p>But it destroys when it enters the player, and it also destroys when hitting the fireball.
  The fireball and it's children are called &quot;fireball&quot; and the player and children are called &quot;player&quot;, it still destroys the fireball gameObject.</p>
  <p>Any idea why this isn't working?</p>
