title: how to move sprite texture using AndEngine (Android) GLES 2
body: <p>I have created texture with TextureOptions.REPEATING_BILINEAR option.
  Now I need to continuously move the texture position inside the sprite in order to create sliding effect without changing of sprite position.</p>
  
  <p>I tried </p>
  
  <pre><code>sprite.getTextureRegion().setTextureX(20);
  </code></pre>
  
  <p>without any success. It only works before the sprite was created.</p>
  
  <p>How to correctly implement it ?</p>
