Nasal based Independant Ramp Marshall

Postby omega95 » Tue Aug 06, 2013 5:41 am

Hey, I've been working on a ramp marshall script (currently, it only moves 1 ramp marshall) - see the video below. :)

(Note that the ramp marshall is a modification of waldo from the bluebird - I redressed him, modeled a headset and glow sticks)

Early Development Animation Test


Aircraft Guidance Test at WSSS B8


That was a prototype only to test the general script and the animations. I'm working on a larger system similar to the animated jetways (but that looked like it had a lot of unecessary code in it) to generalize this and make the animations independant. I made some progress and had a lot of questions but figured them out myself so far. I suppose I could ask more questions here then?

Oh, and how exactly can I (would you want to have this?) add this to fgdata for the next release? So far, it only works with the WSSS Airport I'm working on, but with this system completed, you should be able to place the marshalls anywhere (at any airport) using the ufo and use a converter script to convert the stg into the xml file that contains the data. :)

Lol, I already ran into trouble... Here's the function I wrote that loads the ramps at a given airport from xml file -

Code: Select all
var load_ramps = func(icao) {

   var xml_file = getprop("/sim/fg-root") ~ "/AI/Airports/" ~ icao ~ "/ramps.xml";
   
   var rampsTree = "/airports/"~icao~"/ramps";
   
   setprop(rampsTree~"/loaded", 1); # Set Loaded flag so flightgear doesn't load again
   
   io.read_properties(xml_file, rampsTree);
   if(rampsTree == nil) {return;}
   
   var ramps = props.globals.getNode(rampsTree).getChildren();
   
   foreach(ramp; ramps) {
      # General Runtime XML
      var index = ramp.getIndex();
      var base_model = getprop("/sim/fg-root") ~ "/Models/Airport/Ramp/ramp.xml";
      
      var tmp = ramps.getNode("models",1).getNode("model", 1);
      tmp.getNode("path", 1).setValue(base_model);
      
      var tree = rampsTree ~ "/ramp[" ~ index ~ "]/";
      
      var params = tmp.getNode("overlay", 1).getNode("params", 1);
      params.getNode("left-arm-x", 1).setValue(tree~"left-arm-x");
      params.getNode("left-arm-outer-x", 1).setValue(tree~"left-arm-outer-x");
      params.getNode("left-arm-z", 1).setValue(tree~"left-arm-z");
      params.getNode("right-arm-x", 1).setValue(tree~"right-arm-x");
      params.getNode("right-arm-outer-x", 1).setValue(tree~"right-arm-outer-x");
      params.getNode("right-arm-z", 1).setValue(tree~"right-arm-z");
      params.getNode("toggle-ramp-marshall-script").setValue("ramp.toggle_marshall(" ~ index ~ ");");
      
      var model_path = getprop("/sim/fg-home") ~ "/state/ramp-" ~ index ~ ".xml";
      
      io.write_properties(model_path, tmp.getPath());
      
      # Add model to FlightGear
      addModel(model_path, ramp.getNode("latitude-deg").getValue(), ramp.getNode("longitude-deg").getValue(), ramp.getNode("altitude-m").getValue(), ramp.getNode("heading-deg").getValue());
   }

}


I get the error: non-objects have no members at this line - var tmp = ramps.getNode("models",1).getNode("model", 1);
I'm not very familiar with the props class, I just looked at it from plausible.org earlier today. I was wondering how I can get/create the tree "/airports/WSSS/ramps/models/model/" and put the limb positions and toggle script in there.

Thanks a lot!

Alright, so I finshed a basic working version. (Need to test with a few more - only testing with 1 instance so far) It gets the data from an xml (if it exists) and creates xmls for the animations (most of the animations are in a single file though - the files created at runtime only have property alias params) and loads them accordingly.

Here's the nasal script.

I was hoping someone *cough* Hooray *cough* could clean it up for me and teach me something new today. :mrgreen:

EDIT - I'm still a little confused with the props class so I just replaced the ones that give errors with simple getprops ad setprops for now. :) I'll try to get to work on the ramp placement tool tonight. Cheers!

Some progress on the markings - a little more realistic now. :)

Great work!

I got curious and looked into this, and (quite as usual) I went off on a tangent. I'm not sure this will be of any help, but I post it here just in case. :wink:

Google searching into it, I see that there have been a mess of different hands signals (and sometimes not identical wand signals): ICAO, IATA and NATO that all have changed over time, various variants and the mess that is when different systems are used at different airports and even different airlines. On top of that very few resources like posters and instructional videos seems to tell what system and version they are using. :evil:

The IATA and ICAO and NATO standards seems to be rather harmonised these days though. :) See edit below though. :(

Getting as close to the source as possible the marshalling signals are currently defined in:
  • ICAO Annex 2, Appendix 1, section 5 page APP 1-5. (10th edition, July 2005) - Can be accessed here
  • IATA Ground Operations Manual (IGOM) (2nd Edition)
  • NATO STANAG 3117 - Aircraft Marshalling Signals (8th edition, 27 Mars 2007) - Available directly from NATO(!)
I wonder what system(s) that have been used and are used used in Eastern Europe air forces though.


EDIT: Darn. Comparing the standards myself I find that most of the time the NATO standard does not follow the ICAO one where stated, even though the ICAO standard is older (even considering amendments related to marshalling under normal operations; some signals related to communication with firefighting personnel was added in 2009).

Cool!

Hooray, you missed his problem ;)

You're using the plural here, ramps, which is a vector - ramp is what you want (since it's a props.Node). You can also combine the two getNode paths: «var tmp = ramps.getNode("models/model", 1)»

Also, make sure to use var in your foreach declarations !: «foreach (var ramp; ramps)»

Oh! If you only want to get children with a certain name, add that name as an argument to getChildren: var ramps = whatever.getChildren("models") for example. Right now you iterate through any child of the props.Node.

@Johan, thanks a lot for the sources! Apparently, the video I watched seems to have mixed them up! I guess I'll stick to the ICAO signals because 4 of the 5 signals are correct according to your first source. (ICAO Annex 2)

I'll be changing the signal to move forward and adding the signal to slow down for now. :)

@Philosopher, thanks a lot! I forgot about that, not sure why it still worked though without the var though. :D

Hmm, need some help again.

I'm working on a function that converts stg files created using the ufo into airport ramp xml files.

This is where I'm having trouble - I'm trying to open the file-select dialog.
Code: Select all
fgcommand("dialog-show", props.Node.new({ "dialog-name": "file-select" }));
   setprop("/sim/gui/dialogs/file-select/path", ""));


But I get this error.
Code: Select all
Nasal runtime error: props.setValue() with non-number
  at /home/narendran/fgdata-git/Nasal/props.nas, line 29
  called from: __dlg:file-select, line 22


It points to this line in the file-select.xml dialog file.
Code: Select all
self.getNode("group[1]/input/visible/equals/value").setValue(self.show_files);

Try calling this before that (just a guess):
Code: Select all
setprop("/sim/gui/dialogs/file-select/show-files", 0);

Actually, this worked - I need it to show files to be able to select a file! Well, thanks for pointing me to the issue though! :D

Code: Select all
setprop("/sim/gui/dialogs/file-select/show-files", 1);


And now, you can create multiple instances with the ufo and they all work! :D

Just made some aircraft (most from my hangar and a couple others from fgdata) compatible with the ramps! I'll create a merge request for the updated -set.xml files soon, along with the ramps and a gui style. :mrgreen:

I'll definitely check this out today - but I'm a little concerned that I might run over the little guy :(. However, I have proportional brakes so it shouldn't be a problem ;).

Do we still need the WSSS scenery or can we select our own airport using the file selector and automatically get support?
Thanks,

Well, WSSS is the only airport with ramp marshalls for now but to put it somewhere else, follow these steps -

1. Use the ufo to place the $FGDATA/Models/Airport/Ramp/ramp.xml where you want and export it to stg.
2. Save the file with all the ramps you want somewhere and then start FG up again (ufo works).
3. Run this function in the Nasal Console and select the stg file with the ramps.
Code: Select all
ramp_marshall.convert_stg();

4. Copy the ramps-export.xml file from $FGHOME/Export into $FGDATA/AI/Airports/<icao>/ramps.xml (you have to rename it)

And you should be good to go! Start up and click on a ramp marshall to toggle him. :D

Oh and don't worry about running him over, he's about 20 m from where the nose gear should stop and he'll signal a cross (the slow down and stop signal) when you get close. If you're too close, he'll make the cross abruptly to signal and immediate stop. :)

And after you've come to a stop, click on him again to deactivate him. Else, he'll keep his hands up and get tired, lol. :D
