title: andengine pathmodifier velocity
body: <p>I have the following code for a sprite to follow a path using Andengine. I need to change the speed (velocity) of the sprites moving along the path(). Does anyone know how to vary the velocity along a path?</p>
  
  <pre><code>private void follow_path5(final AnimatedSprite tSprite,int i) {
      final Path path = new Path(5)
      .to(20, startY)
      .to(416.0f, startY)
      .to(20.0f, startY)
      .to(416.0f,startY)
      .to(20.0f,startY);
  
      // Add the proper animation when a waypoint of the path is passed.
      tSprite.registerEntityModifier(new PathModifier(30.0f, path, null, new IPathModifierListener() {
          @Override
          public void onPathStarted(final PathModifier pPathModifier, final IEntity pEntity) {
  
          }
  
          @Override
          public void onPathWaypointStarted(final PathModifier pPathModifier, final IEntity pEntity, final int pWaypointIndex) {
  
              switch(pWaypointIndex) {
              case 0: case 1: case 2: case 3:
                  final long[] frameDurations = new long[3];
                  Arrays.fill(frameDurations, 500);
                  tSprite.animate(frameDurations, 2, 4, true);
  
                  break;
  
              case 4: case 5: case 6: case 7:
                  final long[] frameDurations1 = new long[3];
                  Arrays.fill(frameDurations1, 500);
                  tSprite.animate(frameDurations1, 5, 7, true);
  
                  break;

                  tSprite.animate(frameDurations2, 2, 4, true);
  
                  break;
  
              case 12: case 13: case 14:
                  final long[] frameDurations3 = new long[3];
                  Arrays.fill(frameDurations3, 500);
                  tSprite.animate(frameDurations3, 5, 7, true);
  
                  break;
              }
          }
  
          @Override
