Passing an object from script to C

Okay, so when you operate on the object that called a method, it's easy to access it from C++. For instance,
%value = %myObject.getVernValue();

ConsoleMethod(t2dSceneObject, getVernValue, const char*, 2, 2, "() Blah blah...\n")
{
    return object->getDataField(StringTable->insert("vern"), NULL);
}

But what if I want to pass a second object to the C++ function? How can I access that object from C++ in the same way? i.e.

%value = %myObject.getVernValue( %secondObject );

ConsoleMethod(t2dSceneObject, getVernValue, const char*, 3, 3, "() Blah blah...\n")
{
   TorqueObject secondObject = doSomething( argv[2] );

   return object->getDataField(StringTable->insert("vern"), NULL);
}


The first line in that function is bogus... but I'm guessing there should be some code that would be similar to that that would convert an Object's ID into an actual object pointer usable from C++.... some sort of a "lookUpObject" function. I just don't know what its name would be.

Thanks again... this should be the last of my C++ questions for a while. ;-)

You need to find the object using its ID value. I'm assuming that %secondObject will contain the ID reference, or name of the second object, so you should be able to do something like this:

ConsoleMethod(t2dSceneObject, getVernValue, const char*, 3, 3, "() Blah blah...\n")
{
    t2dSceneObject* secondObject = dynamic_cast<t2dSceneObject*>(Sim::findObject(argv[2]));
    secondObject->doSomething();
    return object->getDataField(StringTable->insert("vern"), NULL);
}

Awesome, that looks like exactly what I'm looking for... will try it later tonight. Thanks a ton!
