Opus Magnum solutions, if you're interested.

really nice game

DMGregory

Love that game. :) Are these your solutions?

Here's one of my sealants...

And a faster / less frugal one...

Blue Bug

3:03 AM

I dont know what it is but that looks gorgeous

Stephane Hockenhull

Very shiny

DMGregory

It's a Zachtronics game, like pretty much all the others, about building/programming machines to transform particular inputs into particular outputs.

Almo

it is very nice looking

good music and sound presentation

and the writing is pretty good as well

@DMGregory note that I post mine hidden in albums so there are no spoilers for people who don't want them :D

DMGregory

Ahh, fair point. Think I should remove those just in case?

Almo

add almo2001 on steam to get my scores in your tables

:D

DMGregory

So far my circle have mostly been sharing them on Twitter so they're out in the clear. Since the workings of the machines can get pretty intricate, so far I haven't had any spoiler problems - it's been easy enough to glance and keep scrolling without stopping to reverse engineer how they did it.

Almo

haha yeah

:)

so far, i only have Lokkij playing it, and the only things I beat him on are area or cost

his cycles are always pretty good

DMGregory

Here's my most absurd so far (Explosive Phial, 25 cycles). :)

> I am developing a platformer in Pygame with the eventual hope of releasing it on Steam.

Is it okay to edit questions to remove the user's life story?

DMGregory

If I have more substantive edits to make, I'll sometimes trim out the "Hi, can anyone help me with this..." preamble. But unless they're going on for a paragraph I usually don't edit solely to de-fluff.

Stephane Hockenhull

welp, I read the rest of the question and it's essentially asking for opinions...

DMGregory

3:25 AM

That sentence on its own looks like it contains useful info, (genre, language, target platform) so I wouldn't consider it high-priority to precis it down.

Stephane Hockenhull

And there's 3 questions in the user's question..

DMGregory

I think we could edit to make it one question: "How can I extend this method to support aftermarket controllers across multiple OSes?"

Stephane Hockenhull

The game genre is irrelevant tho.

Yeah your version would be much better.

DMGregory

I wouldn't say it's completely irrelevant - there are patterns of input common to many platformers, and it makes it clear that identifying a consistent "jump" button across after-market controllers would be important in this context. It might not affect the answers much, but given how many insufficiently-detailed questions we get, I'm happy to err on the side of allowing a little extra info. ;)

Stephane Hockenhull

Hehe.

DMGregory

3:34 AM

Overall, I have to say that question shows an impressive amount of research compared to most that we get. If we're able to clean up the 3-way split at the end, I think it will be a high-quality addition to the site. :)

DMGregory

3:45 AM

There, I tried a combination. It's not super elegant, but hopefully it sets it in a useful direction.

good day

user92578

I'm trying out Texture Packer

user92578

Younger Tyyppi would've probably just written a naive Python script but now I want to at least try using an existing tool

Alexandre Vaillancourt

12:36 PM

Tools are useful, when they work and when they do what you want them to do :)

Writing tools is fun :P

nwp

Writing a regex->DFA converter was no fun for me :(

Alexandre Vaillancourt

@nwp I don't know what that is :)

nwp

I'm gonna chose the "Path of the engineer" skill for my next attempt and just hardcode it until it becomes a problem.

Alexandre Vaillancourt

@nwp Is that the same as "make it work first, optimize later"?

nwp

@AlexandreVaillancourt Not quite. It's "make the specific solution first and generalize later".

@AlexandreVaillancourt Basically turning (Hello)|(World) into this. I need it for syntax highlighting.

It turns out that keywords are fairly easy, detecting word boundaries is a bit annoying, comments are still doable and raw string literals are insane.

But that mostly comes from having to do it line by line. If I had the full text std::regex would work just fine.

I blame Qt and myself for using it.

user92578

12:53 PM

@AlexandreVaillancourt yeah I agree on this

Alexandre Vaillancourt

@nwp Sorry, I'm not at all aware of any of this :P I've been doing some compiler related stuff but it was more that 10 years ago :P

user92578

const int X, Y;

Alexandre Vaillancourt

@Tyyppi_77 Gotta be careful about the NIH Syndrome.

user92578

studid C++ question: Is Y const?

Alexandre Vaillancourt

I think so.

user92578

1:03 PM

Yeah I think I've improved on the NIH Syndrome

Alexandre Vaillancourt

It's easy to test :)

@Tyyppi_77 This says Y is const :)

user92578

ah thanks

user92578

Isn't that a little inconsistent? Since AFAIK with int*X, Y Y isn't a pointer?

Kevin van der Velden

Pointer-ness is a property of the variable and constness is of the type shrug

It is weird =p

user92578

oh right yeah

Alexandre Vaillancourt

1:10 PM

Yep.

user92578

this is why weird people type the pointer character next to the name

user92578

int *a vs int* a

Alexandre Vaillancourt

Also.

nwp

And some other weird people type int const instead of const int for similar reasons.

Alexandre Vaillancourt

This problem is "fixed" if you limit yourself to declaring only one variable per line:
int* a;
int* b;
int c;

user92578

1:12 PM

yeah

Alexandre Vaillancourt

@nwp Yeah, I remember that const applies to the term at the left of the const, if there are none, it applies to the one on the right. So that's just using the "first part" of the rule.

But const int is "more natural" than int const, so const int FTW :)

nwp

It is supposed to avoid confusion for const int * vs int const * vs int * const.

I still get really confused about where the ...s go in variadic templates. There is probably an intuitive rule.

Alexandre Vaillancourt

Yeah, well in any case, you gotta know what the const applies to, and sticking the const between the int and the * doesn't show it easily.

@nwp I have solved that problem: I don't use it :)

nwp

static thread_local const extern "C" volatile mutable int * const volatile i;

C++ is so much fun!

I'm somewhat disappointed that clang-format doesn't reorder modifiers. I don't even care about the order, I just want it consistent.

Also someone should make a clang-format browser plugin that automagically formats all the code to The One True Formatting Style™.

@nwp Forgot long long unsigned.

user92578

constexpr?

nwp

1:23 PM

Yeah, that one too.

Alexandre Vaillancourt

Not sure consexpr would work with volatile?

nwp

Most of these don't actually work with each other.

Alexandre Vaillancourt

Oh!

I should write some different app than what I'm doing now, then. :P

nwp

A compiler that accepts mutually exclusive storage specifiers?

[[maybe_unused]] constexpr long long unsigned static const volatile int * const volatile i{}; is the best I managed to compile.

For some weird definition of "best".

Alexandre Vaillancourt

@nwp No, apps that would need me to use all of these keywords for a "real" reason :P (sorry for the double ping)

nwp

1:37 PM

I still write (void)x; instead of [[maybe_unused]] x;. I have not found the advantage of [[maybe_unused]] yet.

Alexandre Vaillancourt

Less typing that way.

nwp

It lets you skip retyping the variable name when you want to apply it to a parameter and you don't need a new line. I guess that could be considered significant.
