View.Move() - How does it work? (eg. it moves in "unit
« on: January 30, 2009, 05:57:18 pm »
I'm a little confused on View.Move() and how it works.  The help file says it "moves the view" and the online tutorial says that it moves the view by X "units".  What does that mean?

Does it move the view by X number of pixels?  (eg. scroll the view)

I've tried m_renderWindow.DefaultView.Move(10, 0) and thought it would scroll my view to the right but instead it seems to scroll downward.

Also, I'm just curious but why is there a HalfSize and not just a Size variable? :)

It means the view moves from X units in scene coordinates (i.e. the global ones). And yes, it means the view is scrolling. You can see the view as a 2D camera which is looking at your scene, and is mapped to the window.

That's weird. Can you show more code?

That's usually more useful when the other parameter is the center. If the first parameter was one of the corners, then the full size would make more sense.

Thanks for the reply!  I was able to figure out what I was doing wrong...
