title: Parabolic jump animation using javafx
body: <p>I'm making a simple sidescrolling platformer shooter game using JavaFX. I want a very simple parabolic jump animation for the character. Currently, the character extends StackPane, and it lives on a Scene. I was told to use Interpolator.SPLINE for the jump animation, but it does not seem to be working. 
  Currently, I have: </p>
  
  <pre><code>public void Jump(){
      TranslateTransition translation = new TranslateTransition(Duration.millis(1), this);
      translation.interpolatorProperty().set(Interpolator.SPLINE(.1, .1, .7, .7));
      translation.play();
  }
  </code></pre>
  
  <p>but it does not seem to move at all. My other animation commands (move left and move right) are working using simple translate transition however. What am I doing wrong with the jump function? </p>
