<?xml version="1.0"?> <!-- Throttle qquadrant. December 2001 by John Check, j4strngs@rockfish.net This is an instrument configuration file for the open-source flight simulator FlightGear (www.flightgear.org). The file is an XML-encoded FlightGear property list defining the instrument's layers and actions. Each instrument is composed of layers stacked on top of each other. A layer may be a texture (with transparent parts to show the layers underneath), text, or a special layer that switches between two others (say, to turn an indicator light on or off). Each layer can move independently in proportion to a property value, and text can be generated from property values as well: all of the layer's movements are defined as transformations. Actions are hotspots on the instrument that will respond to a mouse click. Actions always modify the values of properties, either by adjusting them, toggling them, or swaping them with other properties' values. Hacked to create a three step flap quadrant - the flaps are extended/retracted in three steps. 2003/01 Lee Elliott --> <PropertyList> <name>flap quadrant</name> <w-base>22</w-base> <h-base>70</h-base> <params> <flaps-select>/controls/flight/flaps</flaps-select> </params> <layers> <layer> <name>backplate</name> <texture> <path>Aircraft/Instruments/Textures/faces-LE-misc1.rgb</path> <x1>0.0</x1> <x2>0.125</x2> <y1>0.75</y1> <y2>1.0</y2> </texture> <w>22</w> <h>70</h> </layer> <!-- flap --> <layer> <name>flap handle </name> <texture> <path>Aircraft/Instruments/Textures/handles.rgb</path> <x1>0.0</x1> <x2>0.37890625</x2> <y1>0.6015625</y1> <y2>0.72265625</y2> </texture> <w>20</w> <h>30</h> <transformations> <transformation> <type>x-shift</type> <offset>0</offset> </transformation> <transformation> <type>y-shift</type> <property alias="../../../../../params/flaps-select"/> <min>0.0</min> <max>1.0</max> <scale>40</scale> <offset>-20</offset> </transformation> </transformations> </layer> </layers> <actions> <!-- flap extend/retract --> <action> <name>Flap Retract</name> <button>0</button> <x>-20</x> <y>-35</y> <w>40</w> <h>20</h> <binding> <command>property-adjust</command> <property alias="../../../../params/flaps-select"/> <step>-0.34</step> <min>0</min> <max>1.0</max> <wrap>false</wrap> </binding> </action> <action> <name>Flap Extend</name> <button>0</button> <x>-20</x> <y>10</y> <w>40</w> <h>20</h> <binding> <command>property-adjust</command> <property alias="../../../../params/flaps-select"/> <step>0.34</step> <min>0</min> <max>1.0</max> <wrap>false</wrap> </binding> </action> </actions> </PropertyList>
