Giant Caves

Overview
Giant Caves is a Spigot plugin that creates giant underground caves in the world. The caves are generated using Perlin noise seeded by the world seed. Caves are unique to each world.

Giant Caves is compatible with the vanilla world generator and most likely any world generation plugin that implements the chunk generator pattern.

Note
Giant Caves will only generate in a new chunks. To find them you will have to explore new areas or regenerate your world.

Installation

• Stop the server if it is running!
• Download the plugin and put it into your plugins folder.
• Start your Server to make the plugin generate default world configuration files for known worlds.
• Set onlyUseWorldManagers to false in config.yml
• Edit the configuration file to match your needs.
• Restart your server.

Configuration
Within config.yml is a series of key/value pair blocks, one for each world under the "worlds:" key. To bind Giant Caves to a second world, copy the key/value pair block under the existing block.

Below are extended descriptions of each of the configuration keys:

• name : world The name of a world to apply giant caves. This value must match the name of the world in the bukkit.yml file for Giant Caves to attach.
  
  
• sxz : 200 Horizontal stretch (larger number = wider cave). This parameter controls the horizontal stretch of the Perlin density map. Making this value larger will stretch the caves horizontally, increasing both the size of the caves and the spacing between them.
  
  
• sy : 100 Vertical stretch (larger number = taller cave). This parameter controls the vertical stretch of the Perlin density map. Making this value larger will stretch the caves vertically.
  
  
• cutoff : 62 Minimum Perlin density cutoff (-100 to 100). This parameter controls the Perlin density cutoff point between cave and not cave. Lowering this value will increase the overall volume and frequency of caves. Raising it will do the opposite. Values outside the range will be treated as the maximum or minimum values.
  
  
• miny : 6 Lower bound of cave zone. The lowest block layer Giant Caves will populate.
  
  
• maxy : 50 Upper bound of cave zone. The highest block layer Giant Caves will populate.
  
  
• debug : false When true, a layer of obsidian is added to the sky to show you where the caves are. This makes them easy to find.
