title: Additive tweens with Universal Tween Engine in libgdx?
body: <p>I have a sprite looping a tween, like an idle animation. I want to add another tween to it, so they both play at the same time. (For example, if my first tween moves it up, and my second tween moves it right, I want it to move up and right.)</p>
  
  <p>But whenever I play my second tween, it seems to override the first one completely.
  What am I doing wrong?</p>
  
  <p>Here's my code:</p>
  
  <pre><code>Tween.to(sprTurtle, SpriteAccessor.POS_XY, 0.4f)
      .waypoint(posTurtle[0] + (20 * density), posTurtle[1] + (20 * density))
      .target(posTurtle[0] + (30 * density), posTurtle[1])
      .ease(Quad.INOUT)
      .path(TweenPaths.catmullRom)
      .repeatYoyo(Tween.INFINITY, 0)
      .delay(0.1f)
      .start(tweenManager);
  Tween.to(sprTurtle, SpriteAccessor.POS_XY, 1f)
      .target(50, 50)
      .repeat(Tween.INFINITY, 0)
      .start(tweenManager);  
  </code></pre>
