Question by Fractalbase · Jun 23, 2014 at 04:42 AM · positionzoom

How to position rendered graphics in a subsection of the game window

In my 2D game, I have on-screen ui elements that cover part of the bottom and the right. The top left is mostly available for the game environment to be displayed. The issue that I'm running into is determining the best method to center what I'm rendering in the available space. Another issue: I want the ability to zoom the camera in and out. I had been adjusting the z position of the camera to do this. Should I adjust the size of all of my game objects instead?

Essentially, I'd like to be able to render game graphics in a subset of the game screen (a rectangle). I'd like the origin (0, 0, 0) to be at the center of that rectangle. I'd like graphics not in that rectangle to not be drawn. Plus I'd like to know the proper way to zoom in&out centered on the center of that rectangle. Any help?
