title: How to use SimplexNoise for 1D
body: <p>I've been playing around with Simplex Noise. But I still dont know how I should use it right. My Goal is to get a terrain for an Sidescroller game. It shoud have a polygonal style look.</p>
  
  <p>I got the source for SimplexNoise from <a href="https://github.com/Longarmx/3DWorld/tree/master/src/com/longarmx/smplx/noise" rel="nofollow" title="here">here</a></p>
  
  <p>Questions:</p>
  
  <ul>
  <li><p>The method <code>getNoise(int x, int y)</code> what values are they for. what do they change?
  I have seen people using a nested for loop and do <code>getNoise(i + x, j + z)</code>.</p></li>
  <li><p>Why are the values largestFeature, persistance not changeable? Shoud I have more than 1 SimplexNoise class to get diffrent biomes?</p></li>
  </ul>
