Mission Editor

Motivation

See also Missions or Tutorials.

On the forum there is a section regarding missions and tutorials. In this section there is a topic where Marius_A showed some time ago his attempts to provide mission framework for FG (see https://forum.flightgear.org/viewtopic.php?f=79&t=31057)

maybe this is also right direction to provide missions/TE (Tactical Engagement) framework to accompany model scenarios mentioned in this thread.

the creation of a mission editor might go a long way in helping the implementation of such a system. The creation of a "mission editor" is something I have been contemplating for a very long time. The ability to add this type of logic and its execution in a location other than fgdata and the AI GUI might prove useful.

A mission generator should be fairly straightforward to write - after all, it's just a number of variables that are populated in a few nested loops - the main challenge is coming up either with a subset of valid values, or a randomization scheme that can do sanity checking for certain values - or your mission may be flying a MED EVAC mission at night time in an ASK13 :D

Stuart also once explored writing a mission generator using the tutorial system - so it's definitely possible, there isn't anything missing at all - it's mainly a matter of finding people interested in this, and willing to acquire the skills to make this happen - even though the latter should be fairly straightforward - we can probably post the main building blocks for something like this within a few weeks, including code snippets for randomizing aircraft, mission, airports etc

So, it's not exactly difficult, but a matter of finding people willing to pursue this - which kinda applies to the whole missions system.

While we do have a number of folks very familiar with Nasal, most of us are busy with other things - that we often consider "more important" (or at least "more interesting") - but the fact that I am posting here demonstrates that I am interested in seeing this materialize eventually - so, if you are sufficiently motivated, we can post a few snippets of code and teach you enough about Nasal to prototype a simple system and grow it over time.

Background

See also Aircraft Generation Wizard.

a simple GUI would definitely be possible using Canvas, we once prototyped a simple dialog that would allow MapStructure layer elements/symbols to be freely moved around on a map, e.g. for visually placing missions elements (other aircraft, crash/accident sites, objectives, wild fires etc):

FlightGear Missions and Adventures#Gallery

Likewise, a slider could be used for timeline-based editing, and a treeview control could be used for event/branching-based editing
