leper khan posted:Their visual scripting language compiles to native. Not sure if it uses C++ as an intermediary or just dumps an AST for llvm. Lol, blueprint doesn't compile to native, it compiles to UnrealScript bytecode. UnrealScript was the scripting language they used through UE3, and it's not even close to native. Blueprint is useful for simple stuff (designers rigging up level triggers, etc) but in a full production game you don't want any tight loops in Blueprint, because it's very slow. Deffon posted:Haven't used UE that much, but it seems like they still have their homegrown marker macros and generator to implement reflection in C++ (similar to QT?) Yeah, it's this. UObject-derived classes have reflection macros. This also makes it easy to have Actor properties be replicated in network games. It's lightweight enough at runtime, and since UE4 is so popular, tools like Visual Assist understand unreal macros.

Volte posted:In C, a char literal is an integer, not a char. Hmm. I knew C lets you do int literals expressed as multiple characters (like 'AAAA' is 0x41414141) but I didn't realize that all char literals were ints. Pre-OSX Mac APIs used these a ton, for file type/creator codes for file metadata and resource identifiers.

Wipfmetz posted:Didn't know about those. They sound like a neat way to define constant or enum values, but alas, non-standard. And non-standard scares me. I didn't realize they were nonstandard, but byte order alone is justification enough for them not to be. Again, the only example I have of using them was from pre-OS X MacOS, which was designed to be programmed in Pascal or 68k assembly, with C as an afterthought.

If you're planning on console and use any online features (including cloud saves, achievements, etc, plenty of features that are in single player games) you'll likely need some kind of login screen, at least for first run. And you'll definitely need some UI element that shows the user which account they're signed in as, with the opportunity to switch users, before any profile operations are done.

You can, however, eliminate an actual login flow *most of the time*. At first run you'll need to create/link a publisher account, but that might be done silently and unlinked to an email. You still need the EULA flow, though. You can also pre-populate the details if the first-party account is already linked to a publisher account.

My first experience with assembly was learning about the other, secret graphing calculator language that was how you made the good games. Learning about assembly on the Z80 while using weird reverse-engineered headers and accidentally learning about hexadecimal at the same time was a bit weird. I had binders of printed source for ZTetris/Galaxian/etc.

lifg posted:Back when Perl was popular I heard someone say, “Perl is a great second language to learn,” and I think that’s true for a lot of high level languages today. When I was in high school/college, just loving around and learning about UNIX and not needing to actually write maintainable code, Perl felt so freeing. My previous experience was with BASIC, then C++, then assembly, then C. Perl opened up a world of possibilities because it supports basically every possible programming paradigm, so you get to see and gently caress around with a lot of different approaches to programming. Now though, I couldn't imagine wanting to write Perl for a living.

I've never worked with JavaScript and I'm sure it's flawed as hell, but I've worked with God's Own Language (C++) for 20 years and it's a disaster. We figured out a long time ago how to mitigate the disaster, and I'd have to assume that JavaScript programmers have done the same

il2cpp probably does a lot of optimizations in the C++ it emits in order to gently persuade the compiler to do optimizations such as unrolling loops if it makes sense. I wouldn't be surprised if Unity knows what compiler it's going to be ultimately using and can specifically target that. I've only used it with MSVC and clang, but those are both pretty knowable and have directives that can aid optimization.

I was a teenage perl kid, and now my null checks are if (ptr == nullptr) because it makes my meaning explicit and adds some amount of typesafety honestly I can't imagine working in a dynamically typed language for a living. I barely trust my code after it's compiled, letting the compiler yell at me about my many shortcomings is the right move

I'm glad that in the modern C++ codebases I've had exposure to, auto and decltype are only really ever used either idiomatically (no need to specify what the type of container.begin() is) or to simplify when you're already specifying the type one or more times in the declaration.

Rottbott posted:Auto is never as bad as this anyway, because the variable still has a type, and your IDE can tell you what it is. It can still bite you in the rear end if you change, say, the return type of a function that's initializing an auto. Harder to do, but still doable.

ultrafilter posted:https://twitter.com/defunkt/status/1719421402867204537 I have a coworker who once forgot to check his Perforce environment variables before doing a p4 obliterate on a no-longer-needed depot. We had a depot called rolling_vendor that periodically took merges from Epic's UE3 depot, so that we always had latest to compare against locally. The central tech group had started running their own rolling_vendor, so we didn't need ours anymore. Unfortunately they had just cloned the entire configuration from ours, including permissions, so my coworker apparently had full admin rights, and the obliterate went through just fine. At least it was relatively easy to get back, because there weren't any backups. He has an Irish last name that starts with an O', so he's been known as O'Bliterate for the last... 17 years

In college I interviewed for an internship at Microsoft (they'd bring a bunch of recruiters and engineers on campus once a year and interview basically every 3rd/4th year CS student) and I was definitely in my smarmy-Unix-kid phase, which intersected heavily with my any-program-worth-writing-can-be-a-Perl-oneliner phase My interview was being done by a recruiter, not an engineer, but they still asked technical questions. One was "write a function to reverse the order of words in a string". I had done plenty of that type of exercise in school, and I was well-versed in C and to a lesser extent C++, so I could have done a straightforward recursive or iterative algorithm, but the interviewer said I could use whatever language I wanted, and I wanted to show everyone just how fuckin' clever I was so I just wrote "join reverse split;" on the whiteboard and then refused to elaborate. I didn't get the internship.

A million characters is probably pushing it on account of average line length of source being pretty low (whitespace lines, brackets, etc), but I've definitely worked in (non-generated) files that were 50k+ lines, so I could see that biting you. It's funny that it's exactly 1,000,000 and not 2^20 though.
