All Implemented Interfaces:

Direct Known Subclasses:
WorldMapGenerator.LocalMimicMap
Enclosing class:
WorldMapGenerator
public static class WorldMapGenerator.LocalMap
extends WorldMapGenerator
A concrete implementation of WorldMapGenerator that does no projection of the map, as if the area were completely flat or small enough that curvature is impossible to see. This also does not change heat levels at the far north and south regions of the map, since it is meant for areas that are all about the same heat level. Example map, showing lack of polar ice

    • LocalMap

      public LocalMap()
      Constructs a concrete WorldMapGenerator for a map that can be used to wrap a sphere (as with a texture on a 3D model), with seamless east-west wrapping, no north-south wrapping, and distortion that causes the poles to have significantly-exaggerated-in-size features while the equator is not distorted. Always makes a 256x128 map. Uses FastNoise as its noise generator, with 1.0 as the octave multiplier affecting detail. If you were using LocalMap(long, int, int, Noise2D, double), then this would be the same as passing the parameters 0x1337BABE1337D00DL, 256, 128, DEFAULT_NOISE, 1.0.

    • LocalMap

      public LocalMap​(int mapWidth, int mapHeight)
      Constructs a concrete WorldMapGenerator for a map that can be used to wrap a sphere (as with a texture on a 3D model), with seamless east-west wrapping, no north-south wrapping, and distortion that causes the poles to have significantly-exaggerated-in-size features while the equator is not distorted. Takes only the width/height of the map. The initial seed is set to the same large long every time, and it's likely that you would set the seed when you call WorldMapGenerator.generate(long). The width and height of the map cannot be changed after the fact, but you can zoom in. Uses FastNoise as its noise generator, with 1.0 as the octave multiplier affecting detail.
      Parameters:
      mapWidth - the width of the map(s) to generate; cannot be changed later
      mapHeight - the height of the map(s) to generate; cannot be changed later

    • LocalMap

      public LocalMap​(long initialSeed, int mapWidth, int mapHeight)
      Constructs a concrete WorldMapGenerator for a map that can be used to wrap a sphere (as with a texture on a 3D model), with seamless east-west wrapping, no north-south wrapping, and distortion that causes the poles to have significantly-exaggerated-in-size features while the equator is not distorted. Takes an initial seed and the width/height of the map. The initialSeed parameter may or may not be used, since you can specify the seed to use when you call WorldMapGenerator.generate(long). The width and height of the map cannot be changed after the fact, but you can zoom in. Uses FastNoise as its noise generator, with 1.0 as the octave multiplier affecting detail.
      Parameters:
      initialSeed - the seed for the GWTRNG this uses; this may also be set per-call to generate
      mapWidth - the width of the map(s) to generate; cannot be changed later
      mapHeight - the height of the map(s) to generate; cannot be changed later

      public LocalMap​(long initialSeed, int mapWidth, int mapHeight, double octaveMultiplier)
      Constructs a concrete WorldMapGenerator for a map that can be used to wrap a sphere (as with a texture on a 3D model), with seamless east-west wrapping, no north-south wrapping, and distortion that causes the poles to have significantly-exaggerated-in-size features while the equator is not distorted. Takes an initial seed and the width/height of the map. The initialSeed parameter may or may not be used, since you can specify the seed to use when you call WorldMapGenerator.generate(long). The width and height of the map cannot be changed after the fact, but you can zoom in. Uses FastNoise as its noise generator, with the given octave multiplier affecting detail.
      Parameters:

      mapWidth - the width of the map(s) to generate; cannot be changed later
      mapHeight - the height of the map(s) to generate; cannot be changed later
      octaveMultiplier - used to adjust the level of detail, with 0.5 at the bare-minimum detail and 1.0 normal

    • LocalMap

      public LocalMap​(long initialSeed, int mapWidth, int mapHeight, Noise.Noise2D noiseGenerator, double octaveMultiplier)
      Constructs a concrete WorldMapGenerator for a map that can be used to wrap a sphere (as with a texture on a 3D model), with seamless east-west wrapping, no north-south wrapping, and distortion that causes the poles to have significantly-exaggerated-in-size features while the equator is not distorted. Takes an initial seed, the width/height of the map, and parameters for noise generation (a Noise.Noise3D implementation, which is usually FastNoise.instance, and a multiplier on how many octaves of noise to use, with 1.0 being normal (high) detail and higher multipliers producing even more detailed noise when zoomed-in). The initialSeed parameter may or may not be used, since you can specify the seed to use when you call WorldMapGenerator.generate(long). The width and height of the map cannot be changed after the fact, but you can zoom in. FastNoise will be the fastest 3D generator to use for noiseGenerator, and the seed it's constructed with doesn't matter because this will change the seed several times at different scales of noise (it's fine to use the static FastNoise.instance because it has no changing state between runs of the program). The octaveMultiplier parameter should probably be no lower than 0.5, but can be arbitrarily high if you're willing to spend much more time on generating detail only noticeable at very high zoom; normally 1.0 is fine and may even be too high for maps that don't require zooming.
      Parameters:
      initialSeed - the seed for the GWTRNG this uses; this may also be set per-call to generate
      mapWidth - the width of the map(s) to generate; cannot be changed later
      mapHeight - the height of the map(s) to generate; cannot be changed later
      noiseGenerator - an instance of a noise generator capable of 3D noise, usually FastNoise.instance
      octaveMultiplier - used to adjust the level of detail, with 0.5 at the bare-minimum detail and 1.0 normal
