<?xml version="1.0"?> <!-- Default Mixture knob. Started summer 2000 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>Mixture Knob</name> <w-base>64</w-base> <h-base>72</h-base> <params> <engine-mixture-select>/controls/engines/engine[0]/mixture</engine-mixture-select> </params> <layers> <layer> <name>background</name> <texture> <path>Aircraft/Instruments/Textures/misc-1.rgb</path> <x1>0.625</x1> <y1>0.2275</y1> <x2>0.8</x2> <y2>0.415</y2> </texture> <w>64</w> <h>64</h> </layer> <!-- fix texture --> <!--layer> <name>shaft</name> <texture> <path>Aircraft/Instruments/Textures/misc-1.rgb</path> <x1>0.890625</x1> <y1>0.8125</y1> <x2>0.921875</x2> <y2>1.0</y2> </texture> <w>16</w> <h>24</h> <transformations> <transformation> <type>x-shift</type> <offset>-5</offset> </transformation> </transformations> </layer--> <layer> <name>knob</name> <texture> <path>Aircraft/Instruments/Textures/handles.rgb</path> <x1>0.5</x1> <y1>0.0</y1> <x2>1.0</x2> <y2>0.5</y2> </texture> <w>64</w> <h>64</h> <transformations> <transformation> <type>x-shift</type> <offset>-3</offset> </transformation> <transformation> <type>y-shift</type> <property alias="../../../../../params/engine-mixture-select"/> <min>0.0</min> <max>1.0</max> <scale>18</scale> <offset>-22</offset> </transformation> </transformations> </layer> </layers> <actions> <action> <name>small decrease</name> <button>0</button> <x>-32</x> <y>-44</y> <w>32</w> <h>74</h> <binding> <command>property-adjust</command> <property alias="../../../../params/engine-mixture-select"/> <step>-0.01</step> <min>0</min> <max>1.0</max> <wrap>false</wrap> </binding> </action> <action> <name>small increase</name> <button>0</button> <x>0</x> <y>-44</y> <w>32</w> <h>74</h> <binding> <command>property-adjust</command> <property alias="../../../../params/engine-mixture-select"/> <step>0.01</step> <min>0</min> <max>1.0</max> <wrap>false</wrap> </binding> </action> <action> <name>big decrease</name> <button>1</button> <x>-32</x> <y>-44</y> <w>32</w> <h>74</h> <binding> <command>property-adjust</command> <property alias="../../../../params/engine-mixture-select"/> <step>-0.1</step> <min>0</min> <max>1.0</max> <wrap>false</wrap> </binding> </action> <action> <name>big increase</name> <button>1</button> <x>0</x> <y>-44</y> <w>32</w> <h>74</h> <binding> <command>property-adjust</command> <property alias="../../../../params/engine-mixture-select"/> <step>0.1</step> <min>0</min> <max>1.0</max> <wrap>false</wrap> </binding> </action> </actions> </PropertyList>
