All the examples use zero, so I've assumed that was the ownship. I've looked through the code and docs, and searched many of the mailing-list archives, but haven't found any examples or explanations yet.

A idea of how to use this for models in general, followed by understanding the implications and current capabilities for multiplayer otherships would be great. Any help would be appreciated, even references to archived discussions. Thanks! The model number was originally a concept which was thought to provide a hook for accessing the location of a particular model. Basically, it would internally end up going back to the FGLocation object for a particular model in order to reference it's position and orientation data. This would be set up by the model manager, be reserved for just aircraft models, and would provide a method of accessing models as an array of objects, similar to how the view manager sets up views. AFAIK this has not been implemented. The AI models, the scenery model work, the 3D cockpit, aircraft model work has involved a few developers and even so it is very well organized. It probably wouldn't actually take much to index the aircraft models and allow a view mode that rotates through a dynamically modified list of views which are sourced at the location of multiple models (without having to set each view up individually in preferences.xml). Some modifications to the code would be required. Without that happening, or happening right away, you can still acheive something similar by setting up additional views in preferences.xml. If you look at the Look From Tower in preferences.xml you'll see clearly how you can reference position and orientation values from anywhere in the property tree. And if I remember this code correctly, you can probably modify these property paths on the fly. For example if you had a nasal script that changes the string value in /config/eye-alt-ft-path then in fact the source property of the altitude of the view would change, next time the view manager class updates (every frame). Look especially at the update function in the viewmgr.cxx file in FlightGear/src/Main. Hope this helps.

RE: [Flightgear-devel] readXML problems
Erik: Are you calling readXML while another call to readXML is in progress? Norman: Can't be done unless this other call is in a different thread :-) Jon: I'm doing it in standalone JSBSim (calling readXML from within another readXML()). I thought you simply had to provide new arguments. Why would it work perfectly in standalone JSBSim, but not within FlightGear? Doh!!! Of course Norman is right - and JSBSim is not calling ReadXML() while another call to readXML() is in progress. I still don't know what could be causing our abort, though. In standalone JSBSim we use our own compiled easyXML and eXpat code - though I would assume it's the same code SimGear uses. When building with FlightGear we resolve the references at link time with the simgear libs like everyone else. Seemed to work fine. Until it died when called from the propulsion loading code.
