How do I ghost fxRenderObject data properly?

Two Questions regarding a fxRenderObject variation - "myObject".

First:
I added a 'static S32 countInstances' to myObject, which gets incremented/decremented in the constructor/destructor respectivly. "countInstances" is always twice the number of instances declared in my mission-script file. If I understand Melv. May correctly there is a client and server copy of each instance created - so this IS the expected behavior, correct?

If NOT, I have a way bigger problem on my hands :-/


Second:
I have an accessor function "myObject::setVelocity(foo, bar);" which sets mFoo and mBar (with unit-conversions and error checking). Then when myObject::renderObject() =>> myObject::updateVelocity() it uses mFoo, mBar, and some neat interpolation over time to give me the end effect I desire.

It appears when I call my setVelocity(foo, bar); the changes to "mFoo" and "mBar" are made to the "server" object, but the changes are never propagated to the client side, and thus I don't see them in-game. Does this seem reasonable? How do I go about fixing it?


Thanks for any help/pointers. I'm really confused here.

Gross over-simplification for example purposes only...

class myObject : public sceneObject {
public:
void setVelocity( S32, S32);

private:
void renderObject();
void updateObject();

static S32 instanceCount;
S32 mFoo;
S32 mBar;
S32 mLastTime
};

static S32 myObject::instanceCount = 0;

myObject::myObject() { countInstance++; }
my Object::~myObject() { countInstance--; }

void myObject::setVelocity( S32 Foo, S32 Bar) { 
//More complicated, but this is the gist of it.
...
mFoo = foo;
mBar = bar;
mVelocity;
}

void myObject::renderObject( ... ) {
...
updateVelocity();
...
}

void myObject::updateVelocity() {
// 30 lines compressed into three. 
// For example only.

Time curTime = getTime()
Time dTime = curTime - mLastTime;
mVelocity = mFoo * mBar * ( dTime / mTargetTime - curTime ); 
}
