How to change a SimObject in C++ and get the effects in script?

#1 1. Expose a field via initPersistFields.
2. Set values to field from C++ (ie, this->mCount = 12;)
3. Read values from script. (ie, echo(%this.count);)

#2 All objects have an ID number. I would suggest naming the object (using the overload of registerObject that takes a name IIRC) so you can easily access it (ie, by saying MyName.field).

#3 Try waiting more than six hours for a response. Posting many times is not going make people wake up in th middle of the night and answer your questions.

If you change a field that is registered via addField, it will always be in synch both for script and C++. ie,

MyObject::initPersistFields()
{
   addField("someField", TypeF32, Offset(mSomeField, MyObject));
}

MyObject *foo = new MyObject();
foo->registerObject("bikeObject");

In Script:

bikeObject.someField = 10;
echo(BikeObject.someField);

In C++:

Con::printf("%f", foo->mSomeField;

All changes are instantaneous.

#4 It's best to do it in script.

#5 You should be stuffing events from the glove into the move manager so that it is networked properly. Having never worked with the P5 code, I don't know what it's doing now. :)
