Protocol file/property tree - Yoke/Rudder position

Postby slawekmikula » Fri Mar 31, 2017 8:15 pm

Hi all,

I'm implementing interface between http://vfrflight.org application and FlightGear. One question about property tree. Is it possible to get information about yoke position and rudder pedals position independently from the controller. Right now i'm using code as below using first joystick property tree. Unfortunately one can have no joystick and control plane with e.g. mouse or have multiple joysticks and control these values with different ones.

Question: How get yoke/rudder position not from the controller interface ?

Code: Select all
            <chunk>
                <name>getYokeXPosition</name>
                <format>%f</format>
                <type>float</type>
                <node>/device/status/joysticks/joystick/axis</node>
            </chunk>

            <chunk>
                <name>getYokeYPosition</name>
                <format>%f</format>
                <type>float</type>
                <node>/device/status/joysticks/joystick/axis[1]</node>
            </chunk>

            <chunk>
                <name>getRudderPeddalsPosition</name>
                <format>%f</format>
                <type>float</type>
                <node>/device/status/joysticks/joystick/axis[2]</node>
            </chunk>

The control inputs should be:

Code: Select all
controls/flight/aileron
controls/flight/elevator
controls/flight/rudder

The trims are under the same branch.
