title: Jump forward in andengine Android
body: <p>I am developing a Game in which sprite have to jump forward .
  I already explore it and used MoveYModifier for up and then MoveYModifier for down again it is working right except on more then one tap on the screen.But I want to move him forward as well while jump.</p>
  
  <pre><code>                 final Entity playerEntity = move;
                   final float jumpDuration = 3;
                  final float startX = playerEntity.getX();
                  final float jumpHeight = 100;
  
                  final MoveXModifier moveUpModifier = new MoveXModifier(jumpDuration / 2, startX, startX - jumpHeight); // - since we want the sprite to go up.
                  final MoveXModifier moveDownModifier = new MoveXModifier(jumpDuration / 2,startX - jumpHeight, startX);
                  final SequenceEntityModifier modifier = new SequenceEntityModifier(moveUpModifier, moveDownModifier);
  
                  playerEntity.registerEntityModifier(modifier);
                  return true;
  </code></pre>
