## This map script for Civ4 generates a random, earth-like map, usually with a
## 'New World' with no starting locations that can only be reached with
## ocean going technology. Though great pains are taken to accurately simulate
## landforms and climate, the goal must be to make unpredictible, beautiful
## looking maps that are fun to play on.
## 
## -- Summary of creation process: --
## First, a random heightfield is created using midpoint displacement. The
## resulting altitudes are then modified by a plate tectonics scheme that
## grows random plates and raises the altitudes near the plate borders to
## create mountain ranges and island chains.
##
## In generating the plot types from a heightmap, I had found that using
## peaks for high altitude and land for less altitude created large clusters
## of peaks, surrounded by a donut of hills, surrounded again by a donut of
## land. This looked absolutely terrible for Civ, so I made it such that
## peaks and hills are determined by altitude *differences* rather than by
## absolute altitude. This approach looks much better and more natural.
##
## The terrain generator gives the other needed visual cues to communicate
## altitude. Since air temperature gets colder with altitude, the peaks will
## be plots of ice and tundra, even near the equator, if the altitude
## is high enough. Prevailing winds, temperature and rainfall are all simulated
## in the terrain generator. You will notice that the deserts and rainforests
## are where they should be, as well as rain shadows behind mountain ranges.
##
## Rivers and lakes are also generated from the heightmap and follow accurate
## drainage paths, although with such a small heightmap some randomness needs
## to be thrown in to prevent rivers from being merely straight lines.
##
## Map bonuses are placed following the XML Rules but slightly differently than
## the default implimentation to better accomodate this map script.
##
## I've always felt that the most satisfying civ games are the ones that
## provide a use for those explorers and caravels. Though the map generator
## does not explicitly create a 'New World', it will take advantage of any
## continents that can serve that purpose. No starting locations will be placed
## on these continents. Therefore, the likelyhood of a significant new world
## is very high, but not guaranteed. It might also come in the form of multiple
## smaller 'New Worlds' rather than a large continent.

## Version History
## SandBar - A version of Totestra/PerfectWorld to make maps for
## Arabian mods (Legends of Ancients Arabia, Rhye's and Fall: 
## The Sword of Islam, Crossroads of the World, etc.)
##
## 20120612: 
## 1) Made map more Arabia-like: Much bigger tropics, more dry, no snowy peaks
##    fewer map options, flat square map with roundish island on it which will
##    probably connect on some parts at the edge of the map.  Lots of sand.
##
## Totestra - Sam Trenholme's update of PerfectWorld2.py
##
## 20120603:
## 1) The chance of a large continent splitting at the edge of the map
##    has been greatly reduced
## 2) There is now an option to remove coastal mountains and reduce inland
##    mountains
## 3) New map wrap option: PerfectWorld-compatible toric wrap
## 4) All bits in the service tag are now used up.  I'm declaring Totestra
##    finished.
##
## 20120530:
## 1) Added 2-bit "parity" to service tag
##
## 20120527:
## 1) Adding test case for bug reported by En Dotter
##
## 20120526:
## 1) En Dotter feature request: It's now possible to change how the map
##    distributes resources
##
## 20120524:
## 1) New civ placement option: Have all civs placed on the same continent
##
## 20120523:
## 1) New option: Handicap level.  This can give the human player extra
##    starting resources.
## 2) Options to split continents and to have players on the "new world"
##    verified to work.
##
## 20120522:
## 1) "Service tag" added as a sign in maps, so people who forgot to log
##    Python debug information can still get full support.
##
## 20120521:
## 1) Overhaul of selection code; symbolic names are now used instead of
##    numbers
## 2) Map ratios now can be selected (within reason)
##
## 20120519:
## 1) Extra-slow maps disabled; they just put PerfectWorld in to an 
##    infinite loop
## 2) "Fast and cheap" maps tested; they work with all three preset 
##    seeds so I'm declaring these maps stable.
## 3) Iceberg code overhaul: Polar icebergs are now more common in cold 
##    and/or large maps, and less common in smaller and/or warmer maps.
##
## 20120512:
## 1) Faster lower-quality maps now tweaked and fixed.  "fast and dirty" caps
##    the size: if you ask for huge you will get a medium sized map.
## 2) Climate can now be selected and it affects the map
## 3) Begin work on making the map ratio user-configurable
##
## 20120505: 
## 1) Water level can now be adjusted in Civ4's GUI
## 2) It is now possible to use a fixed or a random map seed
## 3) There is an untested ability to more quickly make lower-quality maps,
##    or, likewise, more slowly make better maps.
##
## Perfect World 2, Cephalo's original map generator changelog history:
##
## 2.06 - Fixed a few bugs from my minimum hill/maximum bad feature function.
##
## 2.05 - Made maps of standard size and below a bit smaller. Changed the way I
## remove jungle to prevent excessive health problems. Tiles in FC on different
## continents have zero value. Tiles on different continents will not be boosted
## with resources or hills. Water tiles have zero value for non-coastal cities.
## Water tiles will not be boosted with resources for non-coastal cities, land
## tiles will be boosted instead. (lookout Sid's Sushi!)
##
## 2.04 - Changed many percent values to be a percent of land tiles rather than
## total map tiles for easier, more predictable adjustment. Ensured a minimum
## number of hills in a starting fat cross. Disabled the normalizeRemovePeaks
## function a replaced it with a maximum peaks in FC function. Added bonus
## resources to FC depending on player handicap. Added a value bonus for cities
## placed on river sides.
##
## 2.03 - Fixed an initialization problem related to Blue Marble. Added some
## enhanced error handling to help me track down some of the intermittant bugs
## that still remain.
##
## 2.02 - Fixed some problems with monsoons that were creating strange artifacts
## near the tropics. Added an exponential curve to heat loss due to altitude, so
## that jungles can appear more readily without crawling to inappropriate
## latitudes.
##
## 2.01 - Changed the way I handled a vanilla version difference. Added toroidal
## and flat map options. Made tree amount more easily adjustable. Added a variable to
## tune the level of resource bonuses. Changed the rules for fixing tundra/ice next
## to desert. Added altitude noise to the plate map to improve island chains. Added
## a variable to control heat loss due to high altitude. Implimented a new interleaved
## bonus placement scheme so that bonuses are placed individually in random order,
## rather than all of each bonus type at once. Brought back the meteor code from
## PerfectWorld 1 and eliminated the east/west continent divide.
##
## 2.0 - Rebuilt the landmass and climate model using the FaireWeather.py for
## Colonization map script engine. Improved the river system. Fixed some
## old bugs.
##
## 1.13 - Fixed a bug where starting on a goody hut would crash the game.
## Prevented start plots from being on mountain peaks. Changed an internal
## distance calculation from a straight line to a path distance, improving
## start locations somewhat. Created a new tuning variable called
## DesertLowTemp. Since deserts in civ are intended to be hot deserts, this
## variable will prevent deserts from appearing near the poles where the
## desert texture clashes horribly with the tundra texture.
##
## 1.12 - Found a small bug in the bonus placer that gave bonuses a minimum
## of zero, this is why duel size maps were having so much trouble.
##
## 1.11 - limited the features mixing with bonuses to forests only. This
## eliminates certain undesireable effects like floodplains being erased by
## or coinciding with oil or incense, or corn appearing in jungle.
##
## 1.10 - Wrapped all map constants into a class to avoid all those
## variables being loaded up when PW is not used. Also this makes it a
## little easier to change them programatically. Added two in-game options,
## New World Rules and Pangaea Rules. Added a tuning variable that allows
## bonuses with a tech requirement to co-exist with features, so that the
## absence of those features does not give away their location.
##
## 1.09 - Fixed a starting placement bug introduced in 1.07. Added a tuning
## variable to turn off 'New world' placement.
##
## 1.08 - Removed the hemispheres logic and replaced it with a simulated meteor
## shower to break up pangeas. Added a tuning variable to allow pangeas.
##
## 1.07 - Placing lakes and harbors after river placement was not updating river
## crossings. Resetting rivers after lake placement should solve this. Fixed a
## small discrepancy between Python randint and mapRand to make them behave the
## same way. Bonuses of the same bonus class, when forced to appear on the
## same continent, were sometimes crowding each other off the map. This was
## especially problematic on the smaller maps. I added some additional, less
## restrictive, passes to ensure that every resource has at least one placement
## unless the random factors decide that none should be placed. Starting plot
## normalization now will place food if a different bonus can not be used due
## to lack of food. Changed heightmap generation to more likely create a
## new world.
##
## 1.06 - Overhauled starting positions and resource placement to better
## suit the peculiarities of PerfectWorld
##
## 1.05 - Fixed the Mac bug and the multi-player bug.
##
## 1.04a - I had unfairly slandered getMapRand in my comments. I had stated
## that the period was shortened unnecessarily, which is not the case.
##
## 1.04 - Added and option to use the superior Python random number generator
## or the getMapRand that civ uses. Made the number of rivers generated tunable.
## Fixed a bug that prevented floodplains on river corners. Made floodplains
## in desert tunable.
##
## 1.03a - very minor change in hope of finding the source of a multi-player
## glitch.
##
## 1.03 - Improved lake generation. Added tuning variables to control some
## new features. Fixed some minor bugs involving the Areamap filler
## and fixed the issue with oasis appearing on lakes. Maps will now report
## the random seed value that was used to create them, so they can be easily
## re-created for debugging purposes.
##
## 1.02 - Fixed a bug that miscalculated the random placing of deserts. This
## also necessitated a readjustment of the default settings.
##
## 1.01 - Added global tuning variables for easier customization. Fixed a few
## bugs that caused deserts to get out of control.
