-------------------------------------------------------------------------------- --PerfectWorld3.lua map script (c)2010 Rich Marinaccio --Updated by Bobert13 --version 5 -------------------------------------------------------------------------------- --This map script uses various manipulations of Perlin noise to create --landforms, and generates climate based on a simplified model of geostrophic --and monsoon wind patterns. Rivers are generated along accurate drainage paths --governed by the elevation map used to create the landforms. -- --Version History -- 5b -Fixed and Optimized SiltifyLakes(). Purged the first random number after seeding. -- -- 5a -Fixed the possibility rivers that can't path to a body of water. Minor bugfixes. -- Adjusted YtoX Ratio used in landmass generation. -- -- 5 - Highly optimized with fixes ranging from Oasis placement to crashes. -- -- 4 - A working version of v3 -- -- 3 - Placed Atolls. Shrank the huge map size based on advice from Sirian. -- -- 2 - Shrank the map sizes except for huge. Added a better way to adjust river -- lengths. Used the continent art styles in a more diverse way. Cleaned up the -- mountain ranges a bit. -- --1 - initial release! 11/24/2010 include("MapGenerator"); include("FeatureGenerator"); include("TerrainGenerator"); MapConstants = {} Time = nil function MapConstants:New() local mconst = {} setmetatable(mconst, self) self.__index = self ------------------------------------------------------------------------------------------- --Landmass constants ------------------------------------------------------------------------------------------- mconst.landPercent = 0.29 --Percent of land tiles on the map. mconst.hillsPercent = 0.50 --Percent of dry land that is below the hill elevation deviance threshold. mconst.mountainsPercent = 0.85 --Percent of dry land that is below the mountain elevation deviance threshold. mconst.mountainWeight = 0.7 --Weight of the mountain elevation map versus the coastline elevation map. --Adjusting these frequences will generate larger or smaller landmasses and features.
