- disabled the scripted virtual function module after finding out that it only works if each single class that may serve as a parent for scripting is explicitly declared. Needless to say, this is simply too volatile and would require constant active maintenance, not to mention a huge amount of work up front to get going. It also hid a nasty problem with the Destroy method. Due to the way the garbage collector works, Destroy cannot be exposed to scripts as-is. It may be called from scripts but it may not be overridden from scripts because the garbage collector can call this function after all data needed for calling a scripted override has already been destroyed because if that data is also being collected there is no guarantee that proper order of destruction is observed. So for now Destroy is just a normal native method to scripted classes

inline unsigned GetVirtualIndex(PClass *cls, const char *funcname)
- scriptified the pistol to test if struct member functions work. - made APlayerPawn::PlayAttacking(2) virtual script functions so that mods have better control over player animations. Note that these have no native base so they skip the templated interface for managing virtual functions.

{
// Look up the virtual function index in the defining class because this may have gotten overloaded in subclasses with something different than a virtual override.
auto sym = dyn_cast<PFunction>(cls->Symbols.FindSymbol(funcname, false));
assert(sym != nullptr);
auto VIndex = sym->Variants[0].Implementation->VirtualIndex;
return VIndex;
}
- scriptified a_strifeitems.cpp and a_debris.cpp. - Changed the glass shards so that they do not have to override FloorBounceMissile. It was the only place where this was virtually overridden and provided little usefulness. - made 'out' variables work. - fixed virtual call handling for HandlePickup.

- Moved all virtual function related template code to its own file because it depends on includes that cannot be done in dobject.h.
