Modifying the camera

Hello,

I'm trying to modify the default RTSCamera so that for example when you decrease your orbit distance, the camera zooms in on the center of the screen instead of just changing the height. Right now I am starting with the basics, and am already having some problems.

I have modified RTSCamera::increaseOrbitDistance() to the following, just to see if my changes would take effect:

void RTSCamera::increaseOrbitDistance()
{
	Point2F curPos = Point2F(100,100);
	setCameraPosition(curPos);
	setOrbitDistance(getOrbitDistance() + mDataBlock->mOrbitStep, true);

}

But this code doesn't even work. All that I am expecting it to do is change positions to a static 100,100, but the camera acts like nothing has been done with setCameraPosition.

What am I missing?

Thanks,
Justin

edit: I mentioned decrease orbit distance but in my code I have increase, it doesn't really matter, either way the camera isn't changing positions.
