I don't follow this. In Nasal, as in C, it's just as easy as adding
"dt" (which in this context is a property value) to an internal
variable. But it can be aircraft/model-specific and doesn't require
modifying the fgfs binary.
Surely you aren't advocating having literally a thousand
aircraft/model-specific C++ objects linked into the default binary?
Linked, no. Generated on the fly, yes.
Every AIModel has it's own subtree inside the property tree. On of those
properties (for ballistic models at least) is "sim/time/elapsed-sec".
The value of this property is increased every time the AIManager is run.
The only overhead would be if the property is references by an animation
since the property is tied to a value.
Can't beat that with Nasal.
