Method Details

heightMap

public static double[][] heightMap(int width, int height, double offset)

Returns a randomly generated map of doubles that smoothly change nearby. Commonly referred to as a Height Map. Uses FastNoise to generate coherent heights. The offset parameter is converted to an int seed via NumberTools.doubleToMixedIntBits(double), so it can be any double, even an infinite one, and will still be treated as a valid seed.

Parameters:

width - in cells

height - in cells

offset - a double that changes the sampling process; the range doesn't matter

Returns:

the created map as a 2D double array

heightMapSeeded

public static float[][] heightMapSeeded(int width, int height, int seed)

Returns a randomly generated map of floats. Commonly referred to as a Height Map. Uses FastNoise (producing FBM Simplex noise) to generate coherent heights. Unlike heightMap(int, int, double), this doesn't drop off heights at the east and west edges of the map. As such, it may be more suitable for local maps than world maps, since it is unlikely to tile east-west.

Parameters:

width - in cells

height - in cells

seed - an int that significantly changes the generation process

Returns:

the created map as a 2D float array
