Hi
the generic/event driven input device now has the new feature to "grab" the
device. Setting this flag to 'true' stops the associated driver from
distributing the events to other listeners.
Do explain what this means, here is an example:
Get yourself a USB mouse and attach it as a second mouse to your computer. You
now have two mice controlling your desktop simultaneously. The same for
FlightGear: both mice do exactly the same thing - quite useless.
Now add a file to your data/Input/Event directory with this content:
<PropertyList>
<name>Logitech Logitech USB Optical Mouse</name>
<debug-events type="bool">false</debug-events>
<grab type="bool">true</grab>
<event>
<desc>Y-Axis</desc>
<name>rel-y-translate</name>
<binding>
<command>property-adjust</command>
<property>/controls/flight/elevator</property>
<factor type="double">-.002</factor>
<min type="double">-1.0</min>
<max type="double">1.0</max>
<wrap type="bool">false</wrap>
</binding>
</event>
<event>
<desc>X-Axis</desc>
<name>rel-x-translate</name>
<binding>
<command>property-adjust</command>
<property>/controls/flight/aileron</property>
<factor type="double">.002</factor>
<min type="double">-1.0</min>
<max type="double">1.0</max>
<wrap type="bool">false</wrap>
</binding>
</event>
</PropertyList>
(You might need to adapt the <name> entry to the name of you mouse)
This tells FlightGear to use the specified mouse exclusively and to be the
only application receiving these events from the USB mouse.
You now have one mouse acting as your regular mouse, doing whatever you expect
it to do. Your USB mouse acts as a yoke. Two mice - two different usages.
Perfect for the 5 minute yoke:
