@ -8,6 +8,96 @@ This library is written in support of work on
|
|||
[The Great Game](https://simon-brooke.github.io/the-great-game/codox/Pathmaking.html), but is
|
||||
separate because it may be of some use in other settings.
|
||||
|
||||
## Explanation
|
||||
|
||||
*I'm writing this becaue, having returned to this project after four years of
|
||||
being distracted by other things, I couldn't even remember what it was for,
|
||||
let alone how to use it.*
|
||||
|
||||
### 'STL files'
|
||||
|
||||
'STL' is not an acronym but an abbreviation; an abreviation of
|
||||
'[stereolithography](https://en.wikipedia.org/wiki/Stereolithography)'. Even
|
||||
that name is completely misleading, since there is absolutely no sense in
|
||||
which this is printing with stone.
|
||||
|
||||
What an STL file is is in fact a representation of a mesh, originally intended
|
||||
for use in 3d printing, and therefore taken to be the bounding mesh of a solid.
|
||||
This makes it a better format for representing landforms for games than a
|
||||
simple heightmap, since heightmaps cannot represent things like overhangs and
|
||||
caves.
|
||||
|
||||
STL files come in two subformats: 'ASCII' (which this library can currently
|
||||
read and write), and 'Binary' (which this library can read but not yet write).
|
||||
|
||||
STL files are commonly used in game development and can be imported by all of
|
||||
|
||||
* [Blender](https://docs.blender.org/manual/en/latest/files/import_export/stl.html)
|
||||
* [Godot Engine](https://godotengine.org/asset-library/asset/961)
|
||||
* [Unity](https://github.com/karl-/pb_Stl) (unofficial)
|
||||
* [Unreal Engine](https://github.com/rdeioris/UnrealSTL) (unofficial)
|
||||
|
||||
Additionally, a number of programs exist to convert STL files into other 3D
|
||||
model file formats.
|
||||
|
||||
### 'Superstructure'
|
||||
|
||||
I can't remember if 'superstructure' is a name which I found in reading the
|
||||
literature on STL files, or whether it's one I came up with for my own
|
||||
purposes, but essentially in my usage of it:
|
||||
|
||||
1. [MicroWorld](https://github.com/simon-brooke/mw-engine) is a two dimensional
|
||||
cellular automaton, which I wrote, and which can be used (and which I use) to
|
||||
model ecological processes up to and including human settlement;
|
||||
2. As a two dimensional cellular automaton, it is necessarily essentially a
|
||||
flat mesh, but I essentially drape that over a
|
||||
[heightmap](https://github.com/simon-brooke/mw-engine/blob/master/src/mw_engine/heightmap.clj)
|
||||
to give a sort of notional two-and-a-half dimensional representation;
|
||||
3. As such MicroWorld is a moderately useful tool to transform an imagined land
|
||||
form into a vegetated and populated landscape, with biomes and human habitation
|
||||
distributed naturalistically.
|
||||
|
||||
A 'superstructure', then, in the terms I'm using it, is an intermediary
|
||||
representation between a heightmap and a stereolithography model, which carries
|
||||
data not only about shape, but about biomes, settlement, traversibility and so
|
||||
on. Thus it is a surface across which routes can efficiently be planned.
|
||||
|
||||
A superstructure can currently be constructed from a MicroWorld world, read in
|
||||
from an [Extensible Data Notation](https://github.com/edn-format/edn). There
|
||||
isn't currently a function to construct a superstructure from an in-memory
|
||||
MicroWorld world, because MicroWorld, when working with models of the size I'm
|
||||
using, is hugely memory hungry; but there clearly could be and that is an
|
||||
addition you should expect.
|
||||
|
||||
A superstructure cannot currently be constructed directly from a heightmap, but
|
||||
that would also be a trivial enhancement and is planned.
|
||||
|
||||
```clojure
|
||||
(use 'cc.journeyman.walkmap.microworld :reload)
|
||||
(require '[cc.journeyman.walkmap.vertex :refer [vertex]])
|
||||
(load-microworld-edn
|
||||
"../the-great-game/resources/test/galloway-populated-20240407.edn")
|
||||
```
|
||||
or
|
||||
```clojure
|
||||
(use 'cc.journeyman.walkmap.microworld :reload)
|
||||
(require '[cc.journeyman.walkmap.vertex :refer [vertex]])
|
||||
(load-microworld-edn
|
||||
"../the-great-game/resources/test/galloway-populated-20240407.edn" :mw {}
|
||||
(vertex 1000 1000 10))
|
||||
```
|
||||
|
||||
Note that this is a lot of processing and even on a fast machine is going to
|
||||
take significant walkclock time. You cannot reasonably do it, except for
|
||||
utterly trivial times, during game initialisation; instead you need to do it
|
||||
in the 'baking' phase of game development, and consider the STL file as the
|
||||
resoource to be shipped with the game.
|
||||
|
||||
However, although it is time-expensive, it is not, unlike MicroWorld, either
|
||||
memory or processor hungry. This will not blow up your machine.
|
||||
|
||||
A superstructure can be written to an ASCII STL file.

||||

# Dali performance
|
||||
|
||||
Notes written while trying to characterise the performance problem in Dali.
|
||||
|
||||
## Hypothesis one: it's the way I format the polygons that's the issue
|
||||
|
||||
Firstly, with both versions of `stl->svg` using the same version of `facet->svg-poly`, i.e. this one:
|
||||
|
||||
(defn- facet->svg-poly
|
||||
[facet]
|
||||
[:polygon
|
||||
{:points (s/join " " (map #(str (:x %) "," (:y %)) (:vertices facet)))}])
|
||||
|
||||
we get this performance using the smaller `isle_of_man` map:
|
||||
|
||||
walkmap.svg=> (def ^:dynamic *preferred-svg-render* :hiccup)
|
||||
#'walkmap.svg/*preferred-svg-render*
|
||||
walkmap.svg=> (time (def hiccup (binary-stl-file->svg "resources/isle_of_man.stl" "resources/isle_of_man.svg")))
|
||||
20-05-25 09:21:43 mason INFO [walkmap.svg:82] - Generating SVG for :hiccup renderer
|
||||
20-05-25 09:21:43 mason INFO [walkmap.svg:96] - Emitting SVG with :hiccup renderer
|
||||
"Elapsed time: 86.904891 msecs"
|
||||
#'walkmap.svg/hiccup
|
||||
walkmap.svg=> (def ^:dynamic *preferred-svg-render* :dali)
|
||||
#'walkmap.svg/*preferred-svg-render*
|
||||
walkmap.svg=> (time (def dali (binary-stl-file->svg "resources/isle_of_man.stl" "resources/isle_of_man.svg")))
|
||||
20-05-25 09:22:17 mason INFO [walkmap.svg:82] - Generating SVG for :dali renderer
|
||||

|
||||
"Elapsed time: 890.863814 msecs"
|
||||
#'walkmap.svg/dali
|
||||
|
||||
If we switch the Dali render to use my original version of `facet->svg-poly`, i.e. this one:
|
||||
|
||||
(defn- dali-facet->svg-poly
|
||||
[facet]
|
||||
(vec
|
||||
(cons
|
||||
:polygon
|
||||
(map #(vec (list (:x %) (:y %))) (:vertices facet)))))
|
||||
|
||||
we get this performance:
|
||||
|
||||
walkmap.svg=> (def ^:dynamic *preferred-svg-render* :hiccup)
|
||||
#'walkmap.svg/*preferred-svg-render*
|
||||
walkmap.svg=> (time (def hiccup (binary-stl-file->svg "resources/isle_of_man.stl" "resources/isle_of_man.svg")))
|
||||
20-05-25 09:35:33 mason INFO [walkmap.svg:82] - Generating SVG for :hiccup renderer
|
||||
20-05-25 09:35:33 mason INFO [walkmap.svg:96] - Emitting SVG with :hiccup renderer
|
||||
"Elapsed time: 84.09972 msecs"
|
||||
#'walkmap.svg/hiccup
|
||||
walkmap.svg=> (def ^:dynamic *preferred-svg-render* :dali)
|
||||
#'walkmap.svg/*preferred-svg-render*
|
||||
walkmap.svg=> (time (def dali (binary-stl-file->svg "resources/isle_of_man.stl" "resources/isle_of_man.svg")))
|
||||
20-05-25 09:35:41 mason INFO [walkmap.svg:82] - Generating SVG for :dali renderer
|
||||
20-05-25 09:35:41 mason INFO [walkmap.svg:96] - Emitting SVG with :dali renderer
|
||||
"Elapsed time: 874.292007 msecs"
|
||||
#'walkmap.svg/dali
|
||||
|
||||
No significant difference in performance.
|
||||
|
||||
If we generate but don't render, we get this:
|
||||
|
||||
walkmap.svg=> (def ^:dynamic *preferred-svg-render* :hiccup)
|
||||
#'walkmap.svg/*preferred-svg-render*
|
||||
walkmap.svg=> (time (def hiccup (binary-stl-file->svg "resources/isle_of_man.stl")))
|
||||
20-05-25 09:37:44 mason INFO [walkmap.svg:82] - Generating SVG for :hiccup renderer
|
||||
"Elapsed time: 52.614707 msecs"
|
||||
#'walkmap.svg/hiccup
|
||||
walkmap.svg=> (def ^:dynamic *preferred-svg-render* :dali)
|
||||
#'walkmap.svg/*preferred-svg-render*
|
||||
walkmap.svg=> (time (def dali (binary-stl-file->svg "resources/isle_of_man.stl")))
|
||||
20-05-25 09:38:07 mason INFO [walkmap.svg:82] - Generating SVG for :dali renderer
|
||||
"Elapsed time: 49.891043 msecs"
|
||||
#'walkmap.svg/dali
|
||||
|
||||
This implies that the problem is not in the way polygons are formatted.
|
||||
|
||||
The difference between the two versions of `facet->svg-poly` is as follows:
|
||||
|
||||
### New version, works with both Hiccup and Dali:
|
||||
|
||||
walkmap.svg=> (def stl (decode-binary-stl "resources/isle_of_man.stl"))
|
||||
#'walkmap.svg/stl
|
||||
walkmap.svg=> (def facet (first (:facets stl)))
|
||||
#'walkmap.svg/facet
|
||||
walkmap.svg=> (pprint facet)
|
||||
{:normal {:x -0.0, :y 0.0, :z 1.0},
|
||||
:vertices
|
||||
[{:x 3.0, :y 1.0, :z 1.0}
|
||||
{:x 2.0, :y 3.0, :z 1.0}
|
||||
{:x 0.0, :y 0.0, :z 1.0}],
|
||||
:abc 0}
|
||||
nil
|
||||
walkmap.svg=> (pprint (facet->svg-poly facet))
|
||||
[:polygon {:points "3.0,1.0 2.0,3.0 0.0,0.0"}]
|
||||
nil
|
||||
|
||||
In other words, the new version constructs the `:points` attribute of the `:polygon` tag by string concatenation, and the renderer just needs to output it.
|
||||
|
||||
### Older version, works with Dali only:
|
||||
|
||||
walkmap.svg=> (pprint (dali-facet->svg-poly facet))
|
||||
[:polygon [3.0 1.0] [2.0 3.0] [0.0 0.0]]
|
||||
nil
|
||||
|
||||
This means that the renderer is actually doing more work, since it has to compose the `:points` attribute itself; nevertheless there doesn't seem to be an increased time penalty.
|
||||
|
||||
### Conclusion
|
||||
|
||||
It doesn't seem that formatting the polygons is the issue.
|
||||
|
||||
## Hypothesis two: Dali renderer scales non-linearly with number of objects drawn
|
||||
|
||||
To test this, we need some otherwise-similar test files with different numbers of objects:
|
||||
|
||||
walkmap.svg=> (count (:facets stl))
|
||||
4416
|
||||
walkmap.svg=> (def small-stl (assoc stl :facets (take 400 (:facets stl))))
|
||||
#'walkmap.svg/small-stl
|
||||
walkmap.svg=> (count (:facets small-stl))
|
||||
400
|
||||
walkmap.svg=> (def large-stl (decode-binary-stl "../the-great-game/resources/maps/heightmap.stl"))
|
||||
#'walkmap.svg/large-stl
|
||||
walkmap.svg=> (count (:facets large-stl))
|
||||
746585
|
||||
walkmap.svg=> (def ^:dynamic *preferred-svg-render* :dali)
|
||||
#'walkmap.svg/*preferred-svg-render*
|
||||
walkmap.svg=> (time (dali.io/render-svg (stl->svg small-stl) "dali-small.svg"))
|
||||
20-05-25 10:12:25 mason INFO [walkmap.svg:92] - Generating SVG for :dali renderer
|
||||
"Elapsed time: 32.55506 msecs"
|
||||
nil
|
||||
walkmap.svg=> (def ^:dynamic *preferred-svg-render* :hiccup)
|
||||
#'walkmap.svg/*preferred-svg-render*
|
||||
walkmap.svg=> (time (spit "hiccup-small.svg" (hiccup.core/html (stl->svg small-stl))))
|
||||
20-05-25 10:14:07 mason INFO [walkmap.svg:92] - Generating SVG for :hiccup renderer
|
||||
"Elapsed time: 10.026369 msecs"
|
||||
|
||||
So we have
|
||||
|
||||
| | Dali | | Hiccup | | |
|
||||
| ----------- | ---------------- | ----------- | ------------ | ----------- | ------------------- |
|
||||
| # of facets | time (msecs) | objets/msec | time (msecs) | objets/msec | ratio (Dali/Hiccup) |
|
||||
| ----------- | ---------------- | ----------- | ------------ | ----------- | --------------------|
|
||||
| 400 | 32.55506 | 12.29 | 10.026369 | 39.89 | 3.35 |
|
||||
| 4416 | 874.292007 | 5.05 | 84.09972 | 52.51 | 10.40 |
|
||||
| 746585 | 29,695,695.61 | 0.03 | 16724.848222 | 44.64 | 1775.54 |
|
||||
|
||||
### Conclusion
|
||||
|
||||
What we're seeing is that Hiccup renders more or less linearly by the number of objects (bear in mind that all of these objects are triangles, so essentially equally complex to render), whereas the performance of Dali degrades significantly as the number of objects increases.

|

<p>Firstly, with both versions of <code>stl->svg</code> using the same version of <code>facet->svg-poly</code>, i.e. this one:</p>
|

<pre><code>(defn- facet->svg-poly

|

<p>If we switch the Dali render to use my original version of <code>facet->svg-poly</code>, i.e. this one:</p>

|

</code></pre>

<p>we get this performance:</p>

|

<p>No significant difference in performance.</p>
|
||||
<p>If we generate but don’t render, we get this:</p>
|

<pre><code>walkmap.svg=> (def ^:dynamic *preferred-svg-render* :hiccup)
|

</code></pre>
|
||||
<p>This implies that the problem is not in the way polygons are formatted.</p>
|
||||
<p>The difference between the two versions of <code>facet->svg-poly</code> is as follows:</p>
|
||||
<h3><a href="#new-version-works-with-both-hiccup-and-dali-" name="new-version-works-with-both-hiccup-and-dali-"></a>New version, works with both Hiccup and Dali:</h3>
|
||||
<pre><code>walkmap.svg=> (def stl (decode-binary-stl "resources/isle_of_man.stl"))
|
||||
#'walkmap.svg/stl
|
||||
walkmap.svg=> (def facet (first (:facets stl)))
|
||||
#'walkmap.svg/facet
|
||||
walkmap.svg=> (pprint facet)
|
||||
{:normal {:x -0.0, :y 0.0, :z 1.0},
|
||||
:vertices
|
||||
[{:x 3.0, :y 1.0, :z 1.0}
|
||||
{:x 2.0, :y 3.0, :z 1.0}
|
||||
{:x 0.0, :y 0.0, :z 1.0}],
|
||||
:abc 0}
|
||||
nil
|
||||
walkmap.svg=> (pprint (facet->svg-poly facet))
|
||||
[:polygon {:points "3.0,1.0 2.0,3.0 0.0,0.0"}]
|
||||
nil
|
||||
</code></pre>
|
||||
<p>In other words, the new version constructs the <code>:points</code> attribute of the <code>:polygon</code> tag by string concatenation, and the renderer just needs to output it.</p>
|
||||
<h3><a href="#older-version-works-with-dali-only-" name="older-version-works-with-dali-only-"></a>Older version, works with Dali only:</h3>
|
||||
<pre><code>walkmap.svg=> (pprint (dali-facet->svg-poly facet))
|
||||
[:polygon [3.0 1.0] [2.0 3.0] [0.0 0.0]]
|
||||
nil
|
||||
</code></pre>
|
||||
<p>This means that the renderer is actually doing more work, since it has to compose the <code>:points</code> attribute itself; nevertheless there doesn’t seem to be an increased time penalty.</p>
|
||||
<h3><a href="#conclusion" name="conclusion"></a>Conclusion</h3>
|
||||
<p>It doesn’t seem that formatting the polygons is the issue.</p>
|
||||
<h2><a href="#hypothesis-two-dali-renderer-scales-non-linearly-with-number-of-objects-drawn" name="hypothesis-two-dali-renderer-scales-non-linearly-with-number-of-objects-drawn"></a>Hypothesis two: Dali renderer scales non-linearly with number of objects drawn</h2>
|
||||
<p>To test this, we need some otherwise-similar test files with different numbers of objects:</p>
|
||||
<pre><code>walkmap.svg=> (count (:facets stl))
|
||||
4416

<h3><a href="#conclusion" name="conclusion"></a>Conclusion</h3>
|
||||
<p>What we’re seeing is that Hiccup renders more or less linearly by the number of objects (bear in mind that all of these objects are triangles, so essentially equally complex to render), whereas trhe performance of Dali degrades significantly as the number of objects increases.</p></div></div></div></body></html>

<h3><a href="#merging-exclusion-maps-and-reserved-area-maps" name="merging-exclusion-maps-and-reserved-area-maps"></a>Merging exclusion maps and reserved area maps</h3>
|
||||
<p>It is intended that it should be possible to merge exclusion maps (maps of areas which should be excluded from the traversable area) with maps derived from height maps. These exclusion maps will probably be represented as SVG.</p>
|
||||
<p>This is not yet implemented.</p>
|
||||
<p>Culling facets in ocean areas is implemented and works:</p>
|
||||
<pre><code>(require '[walkmap.core :refer [cull-ocean-facets *sea-level*]])
|
||||
(cull-ocean-facets stl)
|
||||
</code></pre>
|
||||
<p>If sea level in your heightmaps is not zero, e.g. is 5, set it thus:</p>
|
||||
<pre><code>(def ^:dynamic *sea-level* 5.0)
|
||||
(cull-ocean-facets stl)
|
||||
</code></pre>
|
||||
<p>It is <strong>strongly recomended</strong> that you set <code>*sea-level*</code> to a floating point number, not an integer, because numbers are specified in the STL file as floating point, and in Clojure, <code>(= 5 5.0)</code> returns <code>false</code>.</p>
|
||||
<h3><a href="#merging-road-maps-and-river-system-maps" name="merging-road-maps-and-river-system-maps"></a>Merging road maps and river system maps</h3>
|
||||
<p>It is intended that it should be possible to merge road maps (maps of already computed routes) with maps derived from height maps. These exclusion maps will probably be represented as SVG. This is not yet implemented.</p>
|
||||
<p>River system maps are conceptually similar to road maps; this too is not yet implemented.</p>

# Human settlement
|
||||
|
||||
;; This rule set attempts to model human settlement in a landscape. It models
|
||||
;; western European pre-history moderately well. Settlement first occurs as
|
||||
;; nomadic camps on coastal promentaries (cells with four or more neighbours
|
||||
;; that are water). This represents 'kitchen-midden' mesolithic settlement.
|
||||
;;
|
||||
;; As grassland becomes available near camps, pastoralists appear, and will
|
||||
;; follow their herds inland. When pastoralists have available fertile land,
|
||||
;; they will till the soil and plant crops, and in doing so will establish
|
||||
;; permanent settlements; this is approximately a neolithic stage.
|
||||
;;
|
||||
;; Where soil is fertile, settlements will cluster, and markets will appear.
|
||||
;; where there is sufficient settlement, the markets become permanent, and you
|
||||
;; have the appearance of towns. This takes us roughly into the bronze age.
|
||||
;;
|
||||
;; This is quite a complex ruleset, and runs quite slowly. However, it does
|
||||
;; model some significant things. Soil gains in fertility under woodland; deep
|
||||
;; loams and podzols build up over substantial time. Agriculture depletes
|
||||
;; fertility. So if forest has become well established before human settlement
|
||||
;; begins, a higher population (more crops) will eventually be sustainable,
|
||||
;; whereas if human population starts early the deep fertile soils will not
|
||||
;; establish and you will have more pastoralism, supporting fewer permanent
|
||||
;; settlements.
|
||||
|
||||
;; hack to speed up processing on the 'great britain and ireland' map
|
||||
if state is water then state should be water
|
||||
|
||||
;; nomads make their first significant camp near water because of fish and
|
||||
;; shellfish (kitchen-midden people)
|
||||
if state is in grassland or heath and more than 3 neighbours are water and generation is more than 20 then state should be camp
|
||||
|
||||
;; sooner or later nomads learn to keep flocks
|
||||
if state is in grassland or heath and some neighbours are camp then 1 chance in 2 state should be pasture
|
||||
|
||||
;; and more herds support more people
|
||||
if state is in grassland or heath and more than 2 neighbours are pasture then 1 chance in 3 state should be camp
|
||||
if state is pasture and more than 3 neighbours are pasture and fewer than 1 neighbours are camp and fewer than 1 neighbours within 2 are house then state should be camp
|
||||
|
||||
;; the idea of agriculture spreads
|
||||
if state is in grassland or heath and some neighbours within 2 are house then state should be pasture
|
||||
|
||||
;; nomads don't move on while the have crops growing. That would be silly!
|
||||
if state is camp and some neighbours are ploughland then state should be camp
|
||||
|
||||
;; Impoverished pasture can't be grazed permanently
|
||||
if state is pasture and fertility is less than 2 then 1 chance in 3 state should be heath
|
||||
|
||||
;; nomads move on
|
||||
if state is camp then 1 chance in 5 state should be waste
|
||||
|
||||
;; pasture that's too far from a house or camp will be abandoned
|
||||
if state is pasture and fewer than 1 neighbours within 3 are house and fewer than 1 neighbours within 2 are camp then state should be heath
|
||||
|
||||
;; markets spring up near settlements
|
||||
if state is in grassland or pasture and more than 1 neighbours are house then 1 chance in 10 state should be market
|
||||
|
||||
;; good fertile pasture close to settlement will be ploughed for crops
|
||||
if state is pasture and fertility is more than 10 and altitude is less than 100 and some neighbours are camp or some neighbours are house then state should be ploughland
|
||||
|
||||
if state is ploughland then state should be crop
|
||||
|
||||
;; after the crop is harvested, the land is allowed to lie fallow. But cropping
|
||||
;; depletes fertility.
|
||||
if state is crop then state should be grassland and fertility should be fertility - 1
|
||||
|
||||
;; if there's reliable food available, nomads build permanent settlements
|
||||
if state is in camp or abandoned and some neighbours are crop then state should be house
|
||||
if state is abandoned and some neighbours are pasture then state should be house
|
||||
;; people camp near to markets
|
||||
if state is in waste or grassland and some neighbours are market then state should be camp
|
||||
|
||||
;; a market in a settlement survives
|
||||
if state is market and some neighbours are inn then state should be market
|
||||
if state is market then state should be grassland
|
||||
|
||||
;; a house near a market in a settlement will become an inn
|
||||
if state is house and some neighbours are market and more than 1 neighbours are house then 1 chance in 5 state should be inn

## Vegetation rules
|

;; rules which populate the world with plants
|
||||
|
||||
;; Occasionally, passing birds plant tree seeds into grassland
|
||||
|
||||
if state is grassland then 1 chance in 10 state should be heath
|
||||
|
||||
;; heath below the treeline grows gradually into forest
|
||||
|
||||
if state is heath and altitude is less than 120 then state should be scrub
|
||||
if state is scrub then 1 chance in 5 state should be forest
|
||||
|
||||
;; Forest on fertile land grows to climax
|
||||
|
||||
if state is forest and fertility is more than 5 and altitude is less than 70 then state should be climax
|
||||
|
||||
;; Climax forest occasionally catches fire (e.g. lightning strikes)
|
||||
|
||||
if state is climax then 1 chance in 500 state should be fire
|
||||
|
||||
;; Forest neighbouring fires is likely to catch fire. So are buildings.
|
||||
if state is in forest or climax or camp or house or inn and some neighbours are fire then 1 chance in 3 state should be fire
|
||||
|
||||
;; Climax forest near to settlement may be cleared for timber
|
||||
if state is in climax and more than 3 neighbours within 2 are house then state should be scrub
|
||||
|
||||
;; After fire we get waste
|
||||
|
||||
if state is fire then state should be waste
|
||||
|
||||
;; waste near settlement that is fertile becomes ploughland
|
||||
if state is waste and fertility is more than 10 and some neighbours are house or some neighbours are camp then state should be ploughland
|
||||
|
||||
;; And after waste we get pioneer species; if there's a woodland seed
|
||||
;; source, it's going to be heath, otherwise grassland.
|
||||
|
||||
if state is waste and some neighbours are scrub then state should be heath
|
||||
if state is waste and some neighbours are forest then state should be heath
|
||||
if state is waste and some neighbours are climax then state should be heath
|
||||
if state is waste then state should be grassland
|
||||
|
||||
|
||||
## Potential blockers
|
||||
|
||||
;; Forest increases soil fertility.
|
||||
if state is in forest or climax then fertility should be fertility + 1
|
||||
|
||||
## Initialisation rules
|
||||
|
||||
;; Rules which deal with state 'new' will waste less time if they're near the
|
||||
;; end of the file
|
||||
|
||||
;; below the waterline we have water.
|
||||
|
||||
if state is new and altitude is less than 10 then state should be water
|
||||
|
||||
;; above the snowline we have snow.
|
||||
if state is new and altitude is more than 200 then state should be snow
|
||||
|
||||
;; otherwise, we have grassland.
|
||||
if state is new then state should be grassland
