Usage

From source file:com.github.skittishSloth.openSkies.maps.PlanetScreen.java

public PlanetScreen() {
    //        final ElevationParameters elevParams = ElevationParameters.buildEvenRanges();
    //        final ElevationParameters elevParams = ElevationParameters.buildByPercent(75, 5, 15, 5, 5);
    final ElevationParameters elevParams = ElevationParameters.buildByEnumValues();
    final LatitudeParameters latParams = LatitudeParameters.getEvenPercentages();
    final TerrainParameters terrainParams = new TerrainParameters(elevParams, latParams, 10, 9, 9);

    final MapGenerator mg = new MapGenerator(terrainParams);
    tileSize = 1;/*from  w w w.j  a v  a2 s  .  c  o  m*/
    width = Gdx.graphics.getWidth() / tileSize;
    height = Gdx.graphics.getHeight() / tileSize;
    tiles = mg.generateTiles(width, height);
