While I got the hang of some SC2 basics, I don't seem to be able to find some variable definitions by searching for them in the manual.
1) I was trying to understand the coding behind the Panning With Touch Controls example, which is pretty straightforward, but I could not find anything on the Touch.X("UI"). What is UI? Doesn't come up in the manual. I understand Touch.X, of course.
2) This tutorial...
Smoke Trail Tutorial
refers to a lot of built in coding in SC2 itself (instance variables, indices...)
In trying to understand the code, I could not find anything on "parent" and I searched all instances of it in the manual. I sort of understand it, but it makes me wonder how many other things I don't know.
I would like to understand the code and what it's doing rather than just blindly copying people's examples every time I need something.
I did some programming in BASIC back in Commodore 64 days, but as a top level language I figure SC2 should not be that hard.
Where do I go to find out what's under the hood and how it works?
Does a tutorial have to exist to describe it?
Basically, rather than learning about everything piece by piece from other people's code, I'd like the whole breadth of it.
