"/sim/signals/fdm-initialized" triggers _every_ time the FDM is reset,
so for every sim reset/relocate.
We need to uninstall the listeners after its first execution, or guard
certain parts of the initialization, to avoid starting multiple
"timer/update loops", or installing multiple property listeners.
Repeating "sim reset" often enough would eventually completely block/
overload the system.
When user switched to a different view mode (e.g. chase/helicopter/tower
view) before or during a tutorial, everything went wrong...
Need to control (save/restore/switch) the view number (view mode) during
tutorials. Also adds an option to explicitly change view mode during
a tutorial, i.e. tutorials can switch to tower view, chase view, ... now.
aircraft system, rather than "core" data.
Fix a long standing annoyance (for me anyway) when the fly-by-view is first
instantiated, it never put a point forward very far so the first transtion
came very quickly and abruptly. Improve the forward prediction based on
ground speed and time when the view is reset (or switched to.) I like this
a lot better personally.
- new parameter naming (left/right instead of min/max; signs are ignored)
- fix wrap-around skips
- use regular constructor so as not to confuse people ;-)
If a <view> contains a <limits> block, then a view handler gets attached to
it, which limits head turns to a given range, whereby headings beyond a given
threshold cause an additional sideways movement. This is turned off by default
for now.
These are then skipped with view.stepView(n), unless the second, optional
argument is set to 1: view.stepView(n, 1);
Whether a view is enabled or not, is saved in $FG_ROOT/.fgfs/autosave.xml
(system views) or $FG_ROOT/.fgfs/aircraft-data/<aircraft>.xml
I tried it the nice way, but it didn't work. Why is it important to
reserve indices for fgfs? Because someone has otherwise to go through
all aircraft in CVS and move aircraft specific views out of the way,
every time a system view gets added. Been there, done that.
a regular function argument for that. Note the "n" in this example:
setlistener("/sim/current-view/view-number", func(n) {
setprop("/sim/hud/visibility", !n.getValue());
}, 1);
