>>55666651
if your program can't recover from a failure in that function, then just throw instead of returning a nonzero value

>>55666673
C

>>55666673
Probably neither, depends on what kind of shitty games you want to make

>non-free software

>>55666738
yes, but it's a mess and I don't think it's really used much

>>55666673
C# + Unity will get you going quicker whether 2D or 3D.

Reposting my question, is there any ready solution for storing tags akin to leveldb?

>>55666752
>>55666774
You are not going to finish and program an entire game without using a engine

>>55666794
Bullshit

>>55666794
I know, that's why I recommended Unity + C#.

Fuckton of tutorials, lots of free assets, easy to get in to.

>>55666805
Truth

>>55666794
3d maybe, but 2d is pretty much doable all by yourself.

>>55666815
No, unless if you are useless as a programmer.
I am seriously unsure what you are doing here.

>>55666819
>>55666832
Do you know how very long it would take you to build an engine to manage all the assets in your game? Many years compared to using an already made engine which is where you both are wrong

>>55666843
Define "manage all the assets in your game". For my pokemon clone it took a few minutes.

>>55666819
>2d is pretty much doable all by yourself
Maybe for the most basic of 2D games, which is frankly boring and no one will want to play it.

Most "2D" games coming out these days are 2.5D done with something like Unity, even the pixel art games.

>>55666819
>>55666843
It's doable but still a bad idea. You're going to waste a lot of time making an engine of some sort, probably by the time you'll finish it you'll lose all motivation for making an actual game.

Also, I don't know about C#, but C++ doesn't even have any proper frameworks for game development. Most of them are either bare bone or just pretty shit quality.

>>55666843
Ridiculous. You can make a 2D engine in a week or two easily.

>>55666734
>>55666774
Why the hell would you suggest non-free tools?

>>55666879
>but C++ doesn't even have any proper frameworks for game development
You're kidding right?

>Search and replace NULL with nullptr
>program starts crashing

I swear to god I'm going to kill myself

>>55666883
You forgot to count in project management, testing, art creation, project design, ui design, marketing, engine creation, content creation, engine optimization, engine testing, engine porting to consoles and many more things.

Stop being an open-source autist.

Unity is one of the best (if not THE best) platforms for newbies.

There isn't a better open-source alternative that is superior on merits other than simply being open-source.

>>55666928
You mean all those things you have to do with a third party engine anyway?

>>55666896
>>55666929
Just name a few frameworks that have same features as Game Maker (e.g. rendering, physics, asset management) and that are actually battle-tested

You are not going to make a 2d engine as good as game maker studio in a week or two easily

>>55666949
Xenko is better.

Your engine will be made for your game instead of being a general purpose thing which includes a million things your project has no use for that are just there to obfuscate the tools you actually want to use and bloat the executable.

The program never worked in GDB because for some reason vkGetDeviceSurfaceCapabilitiesKHR returns VK_ERROR_SURFACE_LOST when the program isn't run from explorer.

Tbh I'm starting to think Nvidia's Windows drivers just don't like Vulkan. DOOM has been crashing a lot too.

>>55666892
Unreal Engine 4's source code is fully available, but it isn't "free".

I have no dislike for the free software movement, but put bluntly if free tools were viable people would be suggesting them instead. If you're developing a game of any complexity, you don't have years to blow on recreating tools that already exist. It's not simply easier to modify an existing engine, it's your only real option. Especially if you're working alone.

>>55666977
It is one of the best 2d game engines out there

>>55666982
You are not going to make a good 2d engine in a week stop lying to yourself you don't realize how much work goes into a real good 2d engine like game maker studio

Holy shit, that's a lot of money.

>>55666998
>if free tools were viable
The majority of them are.

>people would be suggesting them instead
And they do.

>If you're developing a game of any complexity
You should be able to make its engine in a short amount of time if you are not a pajeet.

>>55667000
you're aware that the actual engine is a lot smaller than all the stuff game maker provides, right?
especially for a small 2d hobby project (while being a competent developer), you don't need all that stuff

>>55666996

Ohh wait you don't have one because it's a difficult project to do on your own you liar!

>>55666998
For 2D dev you don't need fucking UE or Unity, they just contain a ton of shit you're not going to use. You're not going to be recreating those, you're going to create an engine adapted to what you need. You don't need a 3M LOC+ engine for a 2D game, games like Braid and Super Meat Boy are made by one programmer each and are both <100k LOC. Even for 3D dev making your own engine can be viable, as seen in The Witness, Amnesia and SOMA.

>>55667059

You cannot program a reasonably good 2D game in less than a month from scratch.

The only 2d game engine you will ever need is SDL/SFML.

SDL is not even a game engine. SDL is an abstraction layer over input/output devices. It can provide you interface to poll inputs, create windows and blit images. And if you want to use OpenGL, SDL can't even blit images.

>>55667090
Yes, you absolutely can.

You can have the basic structure of a working platformer with assets set up in a day or two.

who /cs50/ here? I'm trying the mario exercise, where you have to print out a half-pyramid of pound symbols aligned to the right. I managed to get it working somehow, but now I have a problem: when I give it certain values for height, like 8 or 23, it prints out pic related.

So my questions is, why is there a bunch of @ in between the #? If I had to guess I'd say that it's because i'm increasing the array index j past the maximum size of s, but as far as I can tell that's not the case. Or am I wrong?

My code (height is an int between 1 and 23 i get from elsewhere):

void MakePyramid(int height)
{
    // For each line
    for (int i = 0; i < height; i++)
    {
        // initialize an array of characters that will contain the spaces and the pounds
        char s[height+1];
        
        // replace each character with a space or a # depending on its position
        for (int j = 0; j <= height; j++)
        {
            if (j < height-(i+1))
            {
                s[j] = ' ';
            }
            else 
            {
                s[j] = '#';
            }
        }
        // print the array
        printf("%s\n", s);
    }
}

I'm talking about 3D.

>Amnesia and SOMA.
Made by a team that developed their engine over a number of years and various projects. eg SOMA's engine was not made from scratch, it was an evolution of Amnesia's. Which was probably an evolution of Penumbra's.

I'm the rigidly self reliant type as well, and I like tightly crafting a program for exactly what I want it to do, how I want it to do it. I don't like working with other people's code, and I don't typically like adding on to an existing project. But there are hard limits to bear in mind, and you have to be realistic. Do I really have the time to research and replicate a highly developed lighting system? Do I have time to sort out all the possible issues with z-fighting, that have largely been solved? Etc.

You have to be realistic. I'm idealistic and stubborn, but I'm also broke and starving and have lived that way for years, and I'm only one person. The days of being able to consistently stay up for days straight are over, which is what I'd have to do to have the remotest chance of producing a working engine from scratch that does what I want and is capable of approximating photorealism.

Look up silent installations for the software you need to install. Most .EXE installers have a /s or /q or /quiet command line switch.

>Ahh so going into the config files and modifying all the files with different linux commands
Most of all enterprise infrastructures are on Windows-based machines, and there's not much to be done with Linux machines that the application vendors don't take care of.

>I am also assuming you look at stack exchange for all different errors that come up
General googling for obscure errors and to see if anyone else in the world has had to do what you're about to have to do.

Now, i would like to put it on the web.

how do i do that? any advice?

thanks

>>55668215
Just use whatever resource you can

>>55668215
Reading a tutorial is usually a lot better than watching videos.

>>55668226
What do you mean 'put it on the web'?
Upload it? Put it in an app store? Have some kind of webside front end?

>>55668226
Do you want to make it a web page?
Use Django.
Do you just want people to be able to download it?
Put it on GitHub.

>>55668235
This. Videos are incredibly inefficient.
They're effectively the same as a well written tutorial and lack the active interaction of someone directly helping you.

>>55668242

>>55668480
I'm playing a shitty game called Space Station 13. I want to (to prove that it can be done and teach myself something) write a program that, when a certain key is pressed, get an item from the backpack, and shoot at the screen (at a particular pixel color). Basically it would be a "cheating" device.

So this involves:

>Running in the background while the game is playing.
>Listening for a certain key combination to be pressed.
>Once the combination is pressed in game, the program will continue
>Move the mouse to a specific location
>Left click
>Search the screen for the appropriate location to click (a certain pixel color)
>Left click

All of this should be done quickly.

Question about style in python.

Learned a little about functional programming recently, so wrote some scripts for work that are structured like:
>bunch of functions, each do one thing and return one value
>at the bottom, have a few lines where the functions are called
>some functions take other functions as arguments

Is having a load of functions calling each other bad stylistically? It looks neat as fuck, but I just wonder from a best practice point of view if its a good idea

>>55669177
It will get to the point where making 15 functions do a tiny little task each will become more cumbersome than creating 2-3 commonly-used functions to perform the majority of the business logic.

Hard to say without seeing how crazy you're getting with the 'purity'.

>>55669579
ok well if you had heard of unit testing
the code in the picture gives you a list of all the values of that type
(except values containing 'undefined')

so if you wanted to test an (a -> b) function called F, you know you could do something like

F <$> (values :: [a])

this is all of the outputs of the function

you could get a random one

let inputs = values :: [a]
let outputs = F <$> (values :: [a])
r <- randomRIO (0, length inputs)
-- length should probably be added to the typeclass
-- this would be a problem for large types
(inputs !! r) -- a random output

I have a MySQL insert statement that always times out if I run it in Python using the MySQLdb connector while it finishes nearly instantly if I directly interface with the MySQL server using either the command line or MySQL workbench.

Could it have to do with the fact that the MySQL server is on a separate machine from the machine running the python script? That doesn't really make much sense to me since MySQL workbench and the command line tool (through SSH) are run from my computer which is separate from the MySQL server too.

Why do companies do this?

With a creative commons share alike license, does the entire program have to be under the same license or just the portions licensed under share alike?

>>55669705
If you own the CC-SA'd thing, you don't have to do shit.

If you are using someone else's in your own code, you need to make the whole thing the same license. If it's just assets though, you don't have to license the code that way.

>>55669689

There's two reasons.

If they're malicious and stupid, they're doing this to prey on jobless saps to get some free work, ignoring how shoddily that will make the results.

If they're just stupid, they're thinking "giving away company library access to every applicant can't possibly backfire," and they might otherwise be reasonable.

If you're desperate, hey, whatever, go for it. Just don't get your hopes up about it being a good and/or real job. I've never heard of any company forcing you to read up on their specifics before a coding challenge. Any assessment of your skills could be done just as easily on a self-contained hundred-line piece of code.

>>55669725
Okay, I'm thinking about getting into drawing and I can't decide which license to use. I've been told that cc0 or one of the creative commons licenses was better suited for art and documentation rather than GPL. Are there any advantages to using cc0?

Could someone else look on this elisp code snippet for me? I've written it around 3 am and read that docstring too often to be able to tell if it makes sense and describes the function sufficiently well.

(defun ltools-init-hook (hook local &rest body)
  "Initialize HOOK, wrap and add all expressions in BODY.

Overall this function is a rather thin wrapper for `add-hook'.
HOOK will be (re)set to nil, all expressions in BODY will be
wrapped into a lambda expression and then added to the value of
HOOK.  The first expression in BODY will be the first in HOOK,
and so on. If an expression in BODY is redundant, it will only be
added once, the first time it appears.

The second argument, LOCAL, if non-nil, says to modify
the hook's buffer-local value rather than its global value.
This makes the hook buffer-local, and it makes it a member of the
buffer-local value.  That acts as a flag to run the hook
functions of the global value as well as in the local value.

HOOK should be a symbol, and BODY should consist of quoted valid
Elisp expressions. HOOK is always first set to nil.
The return value of ltools-init-hook is the value of HOOK."

  (set hook nil)
  (dolist (expr body (eval hook))
    (add-hook hook `(lambda () ,expr) t local)
    )
  )

Why would you say that? It's already a thing. Not in any mainstream OS, but like I said, in academia. Normally the OS runs on top of the hardware and the runtime runs on top of the OS, but in this case that relationship is simply flipped. The research is mostly based on developing ultra secure OSs, but performance has been pretty similar to a "normal" OS as well.

what does the u signify here? I see this a lot in the data the API sends me. What's the right way to handle this programmatically? What kind of data structure is this?

are you including if they use a library like SDL or no?

i made a pretty shitty rpg game using sdl. only put like 30 hours in, but it came out alright for a first timer.

Just some random range, wanted to pick a 32bit signed integer but I fucked up, should be -2**31,2**31

lol, there must be a better way of generating a random list than making a for loop, that seems highly inefficient

It's a unicode string

>>55671083
it's a unicode string, handle it like any other string

data structure, is a dictionary in a list

that's not something you learn you idiot, that's something you deduce, here you're asking people to do that work for you. while what programming is, IS doing that work. So if you can't do it buddy boy, go home and play your vidya.

Integer a = 127;
Integer b = 127;
System.out.println(a == b); //true
a++; b++;
System.out.println(a == b); //false
a--; b--;
System.out.println(a == b); //true

We're dealing with someone that resorted to frogposting after they couldn't google something properly. It isn't a good idea to stress him too much more.

>that speed comparison
jesus FUCK how come we don't use that?

>not a randomly selected integer in range x, just a random fucking list of 1024 integers to be fucked with at a later point
because
>randomly selected integer
has bounds of (-Inf,+Inf). the set of numbers your computer can actually even store in memory is infinitesimally smaller than the set of all numbers it could possibly generate if all you ask is
>random list of 1024 integers
that's why you have to specify a range
