Creatures 2 World Engineering Information
Here you will find information about the physical world of Albia; it's rooms, environment and attributes.
Room Info
Each room has a concept of inorganic
nutrients. This roughly corresponds to a soil type and
allows the world to be broken down into soil regions. The
table below shows the divisions and intentions used when
creating the Albia that shipped with C2.
| 0-10 |
Dust |
| 10-20 |
Caves - bare |
| 10-70 |
Desert |
| 70-120 |
Caves - fertile |
| 80-150 |
Temperate forest |
| 100-200 |
Tropical forest |
| 200-255 |
Swamp |
As shipped, the inorganic nutrients do not change with
time but it is possible to create a mechanism using the CAOS
language that allows them to change.
Each room also has a concept of organic
nutrients and these change with time. This roughly
corresponds to organic matter that accumulates from the death
of organisms and is removed by detritivores and fungi. The
Albian fungi relies on the presence of organic
nutrients to grow and uses them up as it does so. If you
find you have an area that the fungi no longer grows in it may
be because there is no more organic nutrient left - one remedy
for this is to use the goldfish egg launcher to fertilise the
room!
Each room has a concept of having a door to a
neighbouring room - a door can be a join in any direction. The
value of the door represents what sized agents can pass
through it. As shipped, the door values in use are shown
below:
| 0 |
Fully closed - nothing can pass
through |
| |
|
| 10 |
Soil boundary - used in rooms that
have a soil floor |
| |
|
| 100 |
Wooden walkway |
| |
|
| 120 |
Lift Shaft |
| |
|
| 255 |
Fully open - everything can pass
through |
Surface rooms have the values for heat, light and
radiation altered based on the time of day and
season.
Atmosphere rooms have the values for light and
radiation altered based on the time of day and
season.
World
Info
1 time-of-day segment (i.e. dawn) last 3600 ticks -
approximately 6 minutes.
1 day lasts 5x3600 ticks = 18000 - approximately 30
minutes
1 season lasts 4x18000 ticks = 72000 - approximately 2
hours
1 year lasts 4x72000 = 288000 - approximately 8
hours
The world is 8352*2400 pixels in size
Scenery
To remove all scenery items from the world you can use
the following CAOS fragment:
Weather system
The weather system in C2 models water vapour released
from the oceans, which then moves around the wind based on
prevailing winds, temperature and water content. When the
conditions in the cloud are such that the water can no longer
be held it will start to precipitate - the type of
precipitation based on the temperature. If the water content
builds up to a high level and is still not able to be
precipitated a storm will develop. If you have no clouds left in your world it will be because the air above the seas is too cold for water vapour to leave and form clouds. If you never see snow, but only see rain then simply the world is too warm for snow to form.
