Talk:Property tree

TODO

• new page: Property

To add

Setting a property that does not exist in the property tree creates it. This gives you the ability to create your own properties in the FlightGear property tree just by bringing them into existence in your NASAL scripts or XML files.

Suggestion

I've been looking at the README.protocol which is here:

http://cvs.flightgear.org/viewvc/source/docs-mini/README.properties?view=markup

This seems to be broken down into two main areas as follows

• Controls
  • Flight Controls
  • Engines
  • Fuel
  • Gear
  • Anti-Ice
  • Hydraulics
  • Electric
  • .. etc
• FDM (Aircraft Settings)
  • Position
  • Orientation
  • Velocities
  • Engines
    • Common
    • Piston
  • .. etc
• Light
  • Umm?

So that structure is nice and clear to me anyway about where the target property should be.

So the suggested format based on the above would be covering each node. with a brief description Having the nodes in plain text format (for cut and paste), and then a more detailed notes below. Also the nested tructure would make it nice with the navigation

for example

Controls

Flight Controls

Main control surfaces for aircraft, blah blah blah. These are read from the sim on /controlsurfaces/

/controls/flight/aileron
/controls/flight/aileron-trim
/controls/flight/elevator
/controls/flight/elevator-trim
/controls/flight/rudder
/controls/flight/rudder-trim
/controls/flight/flaps
/controls/flight/slats
/controls/flight/BLC			// Boundary Layer Control
/controls/flight/spoilers
/controls/flight/speedbrake
/controls/flight/wing-sweep
/controls/flight/wing-fold
/controls/flight/drag-chute

Speed brakes are only blah blah..

Engines

Engine introduction. Thes appears in the FDM as

/controls/engines/throttle_idle
/controls/engines/engine[%d]/throttle
/controls/engines/engine[%d]/starter
/controls/engines/engine[%d]/fuel-pump
/controls/engines/engine[%d]/fire-switch
/controls/engines/engine[%d]/fire-bottle-discharge
/controls/engines/engine[%d]/cutoff
/controls/engines/engine[%d]/mixture
/controls/engines/engine[%d]/propeller-pitch
/controls/engines/engine[%d]/magnetos
/controls/engines/engine[%d]/boost
/controls/engines/engine[%d]/WEP
/controls/engines/engine[%d]/cowl-flaps-norm
