Const keyword means constant, a value that won’t change after the application has been compiled; this allows for certain optimizations.
Let keyword is a JavaScript variable that is safely scoped down to the method or function level.
Var keyword is generally discouraged in JavaScript, because it’s a global declaration. The value of it could be available anywhere in the application, and the app might have collisions.
So, the meme is, shifting from a constant, unchanging gender, to the middle where gender is defined and scoped to a local level, to the extreme, where gender is variable globally.
Unfortunately, those of us that make games in Unreal Engine are stuck writing a lot of C++, unless we want to do everything in BPs (no thanks, they’re fine, but it’s not coding, and it’s difficult to maintain and refactor for complicated projects, they’re good for taking C++ components and building bigger components out of the base C++ functionality though).
With that said, UE’s support for C++ is decent. Which is, that as long as you tag all your fields, properties, methods, classes, etc. with some UnrealEngine attribute filter (like
UCLASS
orUPROPERTY
), Unreal will handle the memory management of those constructs for you. Which is nice.Unfortunately it has some other limitations to the C++ language that you can’t work around, like disallowing pure abstracts because every C++ derivative class based on any UE construct (Actor, Character, Pawn, etc.) has to be instantiatable in the editor. So no pure abstracts and such.
In general, I’d give it a 6/10.
It’s still mostly C++, but some of the things suck less.
