That puzzled me too. It seems to me that fgfs has some (a lot
of?) 'orphaned' features. The problem is that the code is there,
but there's no way to activate these features, and no
documentation.
For example, I've found that the code supports multiple cloud
layers with varying degrees of coverage, from FEW to OVC. The
required textures appear to be present. Unfortunately users can
only set the cloud base for the first layer. Its coverage is
hard-coded to BKN, and the second layer is hardcoded FEW190.
That's one low-effort high-yield fix found, investigation
continues.
Eventually I'd like to be able to add and remove cloud layers on
the fly. I propose the following properties:
/environment/clouds/layer[n]/
(layers can be added from command-line,
configuration file or on-the-fly.)
altitude-ft (double)
thickness-ft (double)
transition-ft (double)
(what does transition do?)
coverage (double)
[0.0 - 1.0] sky coverage fraction; also obsoletes
status property. (0 -> status=false)
type (string)
Cumulus|Stratocumulus|Stratus|Cirrus
speed-from-north-fps (double)
speed-from-east-fps (double)
moving clouds, not implemented yet (is the
convention for clouds to or from?)
New commands for network properties interface:
mk{bool,int,long,float,double,string}
Create (and set) value of specified type
mkdir, rm (with alias rmdir)
you get the idea
Commands to be changed:
set
refuses to create new nodes (currently creates strings)
cd
refuses to 'enter' nodes with values
Misc:
Design a scheme to prevent deletion of "standard"
properties. (Add a FIXED attribute to SGPropertyNode?)
I'm not touching any weather-related code until this new
environment thing is resolved. I could get started on the network
interface though.
Comments?
