It's comparatively trivial and well tested. I don't expect problems. If you run into one, please tell me. The Nasal scripts are now and . They are executed for all OBJECT_STATIC and OBJECT_SHARED. But note that only OBJECT_STATIC are removed from the scene graph when they are "out of sight", so better use no or very short and inexpensive Nasal code in OBJECT_SHARED objects. m. --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.

How it works
- the model loader has another arg: a pointer to an ssgBase derived
SGModelData class
- if !0 then its load() method is called
- only the caller of scenery models sets such a class: an SGModelData
derived FGNasalModelData class
- the tileloader sets a bool for OBJECT_STATIC for the modellib
loader, so that those can be excluded from the cache map
I've changed the behavior a bit after Andy's suggestion. I'm currently
using two properies and (could be changed to
and -- I just found "on-unload" hard to pronounce. ;-)
New example:
helipad.ac
loaded = 1;
print("Hello, I'm the helipad!");
var f = func {
if (!loaded) { return }
print("I'm still there!");
settimer(f, 5);
}
f();
loaded = 0;
print("Bye, bye!")

It is stable. It's just the pending release that keeps me from submitting. But if it'll take a while to fix the remaining JSBSim aircraft configs, then we can as well apply it now. :-) Don't know about Win binaries. I'm not releasing any builds, and if I would, then they'd be for Linux. To Josh: I'll offer a patch later today. m. --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
