<?xml version="1.0"?> <!-- Improved airspeed indicator instrument. Apr 27 2001 Martin Dressler dr@musicabona.cz airspeed indicator instrument from C172RG GPL _______________________________________________________________________________ Based on Default by David Megginson, david@megginson.com. 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. --> <PropertyList> <name>C172RG Airspeed Indicator</name> <w-base>128</w-base> <h-base>128</h-base> <layers> <layer> <name>gauge face</name> <texture> <path>Aircraft/Instruments/Textures/airspeed-160-knot.rgb</path> <x1>0.5</x1> <y1>0.5</y1> <x2>1.0</x2> <y2>1.0</y2> </texture> <w>126</w> <h>126</h> </layer> <!-- <layer> <name>numbers under hub</name> <texture> <path>Aircraft/Instruments/Textures/airspeed-160-knot.rgb</path> <x1>0.171875</x1> <x2>0.328125</x2> <y1>0.1640625</y1> <y2>0.3203125</y2> </texture> <w>19</w> <h>19</h> </layer> --> <layer> <name>needle</name> <texture> <path>Aircraft/Instruments/Textures/airspeed-160-knot.rgb</path> <x1>0.69921875</x1> <x2>0.84765625</x2> <y1>0.15625</y1> <y2>0.5</y2> </texture> <w>19</w> <h>44</h> <transformations> <transformation> <type>rotation</type> <property>/instrumentation/airspeed-indicator/indicated-speed-kt</property> <min>10.0</min> <max>190.0</max> <scale>1.0</scale> <interpolation> <entry><ind> 10</ind><dep> 3</dep></entry> <entry><ind> 40</ind><dep> 38</dep></entry> <entry><ind> 60</ind><dep> 85</dep></entry> <entry><ind> 80</ind><dep> 146</dep></entry> <entry><ind> 100</ind><dep> 198</dep></entry> <entry><ind> 120</ind><dep> 236</dep></entry> <entry><ind> 140</ind><dep> 274</dep></entry> <entry><ind> 160</ind><dep> 313</dep></entry> <entry><ind> 190</ind><dep> 353</dep></entry> </interpolation> </transformation> <transformation> <type>y-shift</type> <offset>12</offset> </transformation> </transformations> </layer> <layer> <name>glare shield</name> <texture> <path>Aircraft/Instruments/Textures/bezel1.rgb</path> <x1>0.5</x1> <y1>0.0</y1> <x2>1.0</x2> <y2>0.5</y2> </texture> <w>128</w> <h>128</h> <transformations> <transformation> <type>x-shift</type> <offset>2</offset> </transformation> <transformation> <type>y-shift</type> <offset>-2</offset> </transformation> </transformations> </layer> </layers> </PropertyList>
