So that I can zoom in on my 2d character when the action gets intense!
To elaborate, currently when setting up an orthographic camera for a 2d game you specify the size instead of changing the z axis to determine how big ("close") your scene seems. If there was an action to gradiate a size change, it would be functionally equivalent to zooming in.
ie, ortho camera size starts out as 3, quickly "iterates" to 2.
If there's another way of accomplishing this that I don't know about, plz forgive, I'm noob here.
