In addition to being a question I'm posting on the forum, I'm also requesting that this information be elaborated on in the documentation. I have been using the 2d Toolkit for a while now and every time I revisit it, I feel like I need to relearn the particulars of how the tk2dCamera works.
First of all, what is an "ortho size"? What is this the size of? What are the units? What effect is it supposed to have? How would I know what to do with this field without any description whatsoever of what it is? Even the tk2dCamera documentation simply lists this as the "Non centered ortho size of this camera."
Second, how can I simply set my camera bounds (and Game window -- this is important) to, in my example, 768x1024, aka portrait mode on an iPad, but on the PC? I've set my Player settings to have a 768x1024 resolution. I've set my Game viewport to be "Standalone (768x1024)". All looks promising. All looks good. I create a Sprite Collection with a Target Height of 1024 (if that makes any difference) and then check the "Use tk2dCamera" checkbox. I removed the default Unity camera from the scene (so I just have my tk2dCamera). I click Commit. I add a sample sprite.
But without fail, every single time, viewable bounds in my Game window are 384x512, exactly half of what I want (or 1/4th if you want to be pedantic).
Can anyone please explain what I need to do to get a 768x1024 game viewport, and more importantly what these settings mean so that I can better understand what I'm affecting when I change these values? Thanks immensely, and sorry if I sound overwhelmed.
