Assigning Flight Controls to Yoke

[judster]

Need some Help! I am running flightgear on Mac OSX 10.4 and my CH yoke works fine except I would like to assign the buttons on the yoke to certain aircraft commands. Example I would like to assign button 8 to be "Altitude Hold". This should be very simple and should not have to enter a bunch of PC code etc.

Thanks!

Have a look at this wiki page

I hope that will help, as you are right: no need for a whole bunch of pc-programming

Have a look at the file

Code: Select all

data\Input\Joysticks\CH\pro-yoke-usb.xml

It is the the configuration file for your yoke.

You should then be able to identify the button you wish to change, and bind it to whatever command you wish.

If you are intending to bind it to a command that is currently available from the keyboard, then have a look in data\keyboard.xml and copy the appropriate binding from there.

Have fun!

Stefan,

I'm still lost. Where are all these files, like (/FlightGear/joysticks.xml) and (/FlightGear/Input/Joysticks/CH). They are not on my HD. Remember I'm on a MAC. Its all windows and no code files. It's not all that Linux stuff.
They constantly talk about all these xml files. I don't even know what they are where they belong.

Again I don't even know where this file is. When I'm downloading the program to my Apple MAC, I have the application icon a couple readme files and 2 userguides and that is it. I have been on MACs for 20 years now and know them very well and use them everyday for my job and I'm beginning to think that the joystick program files are strictly for Windows/Windows Vista and not MAC

ok, i'll try to give you step-by-step instructions:

1. get a decent editor to edit your xml-files. e.g. smultron at http://smultron.sourceforge.net
2. assuming you have put FlightGear in Applications:
   
   • go to Applications
   • ctrl-click on Flightgear
   • "Show package contents"
   • Navigate to Contents/Resources/data/Input/Joysticks/CH/
   • ctrl-click on pro-yoke-usb.xml and open it with smultron (or drag it to smultron if you have put it in the dock)
   • follow directions elsewhere on how to change the file
   • save the file and launch FlightGear

NOTE: all applications in os x are in fact folders with the extension .app. they usually contain all sorts of application-related data and can be opened and used like any other folder (by using "show package contents")

hope that helps,

- till

I'm almost there, your explanation was very helpful. Below is a code that I copied from the file that I want to change. I want this button to be Altitude Hold or maybe Heading Hold. I can't right code, is there a code reference page that I can copy off of. Or at lease maybe you can do this example for me.

Thanks!

David


<button n="8">
<desc>Increase Engine Boost</desc>
<repeatable>true</repeatable>
<binding>
<command>property-adjust</command>
<property>/controls/engines/engine[0]/boost</property>
<step type="double">+0.01</step>
</binding>
<binding>
<command>property-adjust</command>
<property>/controls/engines/engine[1]/boost</property>
<step type="double">+0.01</step>
</binding>
</button>

You can see /Applications/FlightGear.app/Contents/Resources/data/keyboard.xml to check what command is assigned to what key.

I'll show you an example of assigning "Toggle autopilot altitude lock" so you can do the rest.

1) search "altitude" in keyboard.xml
1.0.0 has a key binding section for locking altitude as shown below:

Code: Select all

 <key n="1">
  <name>Ctrl-A</name>
  <desc>Toggle autopilot altitude lock.</desc>   <!-- you need this -->
  <binding>         <!-- and this (including sub tags) -->
   <command>nasal</command>
   <script>
     var node = props.globals.getNode("/autopilot/locks/altitude", 1);
     if ( node.getValue() == "altitude-hold" ) {
       node.setValue( "" );
     } else {
       node.setValue( "altitude-hold" );
     }
   </script>
  </binding>
 </key>


2) copy & paste the content of <desc> tag to your joystick file
3) copy and paste the lines from <binding> through </binding> to the joystick file

After doing step 2 and 3, the code for button 8 looks like this:

Code: Select all

 <button n="8">
  <desc>Toggle autopilot altitude lock.</desc>
  <binding>
   <command>nasal</command>
   <script>
     var node = props.globals.getNode("/autopilot/locks/altitude", 1);
     if ( node.getValue() == "altitude-hold" ) {
       node.setValue( "" );
     } else {
       node.setValue( "altitude-hold" );
     }
   </script>
  </binding>
 </button>


If you want to use js_demo or jgfs, these are at /Applications/FlightGear.app/Contents/Resources
in 1.0.0 binary package.
