title: How to properly load textures using the libgdx assetmanager
body: <p>Is this how one properly loads a texture into an <code>AssetManager</code>?</p>
  
  <pre><code>Texture tex;
  AssetManager manager = new AssetManager();
  manager.load("menu/bg.png",Texture.class);
  tex = manager.get("menu/bg.png",Texture.class);
  </code></pre>
  
  <p>The texture fails to load with error "cannot load the texture menu/bg.png".</p>
  
  <p>How should we load our texture using the <code>AssetManager</code>?</p>
