== Scenario Loading on Demand ==
== Scenario Loading on Demand ==
To get the ai models on demand I'm using a scenario template then editing it and then loading the model. CALLSIGN and PLANEFILE are replaced by the the property name and the model file appropriate. The amended file is saved in a subfolder:  /AI/rttemp. "load-scenario" command needs a unique file name for each plane and only loads from within AI folder. This means that files will pile up in rttemp and should be deleted at the end of the session.
To get the ai models on demand I'm using a scenario template then editing it and then loading the model. CALLSIGN and PLANEFILE are replaced by the the property name and the model-file appropriate. The amended file is saved in a subfolder:  /AI/''rttemp''. "load-scenario" command needs a unique file name for each plane and only loads from within AI folder. ''rttemp'' is a simlink to '''fg-home'''/cache/rttemp.
This process requires a write access addition to /Nasal/IORules
I do this because fg 2018 allows read write access only to fg-home / cache.
 
 
This means that files will pile up in rttemp and should be deleted at the end of the session.

Input is the latitude and longitude range  and a list of position altitude and speed etc is returned for each plane (looks similar to JSON format, i.e. Nasal hashes).

The capture routine also collects live METAR weather. This can be easily amended for changes in the server.

''setCheck'' changes the click status '''''before''''' calling the function so the function can know what's wanted.
''checked'' just returns whether the box is checked or not.
In '''/gui/menubar.xml''' insert the RealPlanes entry in the AI menu as below:
