Working on my 2D fighting/card game. I think I should work on it a bit more before I talk about the details.
Was working on just a card game, but decided to mix it up. Good code design allowed me to switch the project up with little pain. I just need to put more time into it.

Hello friends
Theoretically how hard is it to build a program to make threads on 4chan? Particularly to force recaptcha v1in the making of new programs
>>51264891
>Theoretically how hard is it to build a program to make threads on 4chan?
easy.
>Particularly to force recaptcha v1in the making of new programs
incredibly hard, probably impossible for most of us.
I'm really just starting out, so I've been working on a simple calculator program.
I've got a question: what kind of IDEs or text editors do you use? If you work with multiple languages, do you use different IDEs or text editors or the same ones?
I've been learning some Qt, is it best to do things programmatically or via the designer?
>>51264933
I use whatever does the job. I primarily work in Visual Studio, but I've worked in a variety of IDE's for different languages.
>>51264852
Take python:from collections import deque
q = deque()
q.appendleft("e")
q.appendleft("n")
q.appendleft("o")
q.appendleft("D")
print("".join(q))

you could buy a pass for your program and have it shitpost endlessly

We need to reinstate the RMS bot.
>>51265013

>>51264933
I primarily use VIM, as it does the job quite well for most languages. But whenever possible I use IntelliJ (pyCharm, rubyMine, webStorm, etc) with ideaVim plugin
I hate applying for jobs. I feel like I know nothing compared to what they ask for.
>>51264971
make sure you separate the program logic and the user interface. Make it so that you can "plug" any interface to it, be it QT, GTK, CLI, whatever
>>51264933
IDE's are generally tied to specific languages as they rely on specific built in compilers. Text-editors (such as sublime text, VIM, etc) show syntax which helps people program but they themselves can't compile or run programs, they rely on external compilers.
>>51265058
This is how my friends described engineering jobs as;
You go to school and learn all this fucking math, then you get your degree. Once you land a job they teach you the tools you need to do the job.
This is probably similar to programming jobs as you have to learn their codebase

Make those class variables private.
>>51265551
I know about that, but I'm not sharing my code nor making a library.
>>51265568
Doesn't matter, you should follow Java style and conventions when writing Java code.
>>51265568
It's good practice either way. You become a better programmer by applying good code conventions even when they're not required.
>>51265599

C++ and Java are the worst offenders but it's pervasive in the community desu.
>>51265180
I wrote a program like this a few days ago
Good luck, that sin/cos shit is a major pain in the ass
>>51265444
everytime you call drawCircle is just adds a number to x_origin. x_origin is always the same and the number you add to it is always the same. That's why it doesn't move.
>>51265568
Then when you go to fix problems it will be spaghetti code you have to dig through.
But oh well, you won't learn till you make these mistakes.
Riddle me this. I have a data structure that I fill with data, then I push the object into an std::vector, then I repeat the step a bunch of times. Then another function receives that vector (it's actually passed by a reference to the first function to store it), then I iterate over the structure in the second function and all of the members suddenly become empty (as if they weren't initialized), what the fuck is going on?
>you will never have a programming buddy to hang out with
Nobody I know is interested in programming
>>51265678
UpdateCircle* not DrawCircle
>>51265677
>Good luck, that sin/cos shit is a major pain in the ass
high school precalculus is troublesome when you're 15 I know
>>51265682
Have you checked the value each time after adding to the vector. Have you tried stepping through your code with your debugger.
>>51265698
probably you wouldn't agree on what to write anyway, the coolest shit begins with one man
>>51265703
Fuck off its far more complex than that
For example calculating position on an xy plane, storing your desired position in an array and running collision detection from particles on that dynamic object isn't the easiest thing I've ever done
And fyi sin and cos are just functions, without your radian conversions and some way to manipulate them every frame it's meaningless
>>51265678
oh well, it seems using += just give me 20k values.
>>51265751
So difficult!
>>51265763
... :)
>>51265444
I don't really know java and I'm tired as heck right now, but I'm pretty sure in your UpdateCircle method, it just sets the enemy to a fixed position. The value of sin(45)*100 is the same no matter how many times you evaluate it. Multiply 45 by some value that's changing, i.e. the timer float. Also don't you want to call the enemy update method in addition to the UpdateCircle method in your gamemanager's update method?
>>51265755
also, changing x_origin to x gives me a linear movement.
what do guys?
>>51265480
Just set utf-8 encoding in your init file senpai.
>>51265798

Is there a guide to set up vim as an IDE?
By IDE I mean functions such as refactor (rename a variable or function name and it will change all places it is relevant.
Or functions such jumping to the implementation in from a function.
Or functions such as automatically open files belonging to the project but not the files in libraries.
Most vim tutorials are only covering the basics of how to open and write to a file.

Anyone know why am I losing UTF-8 support on one of these lines?
I'm still not used to Haskell types.
Using HDBC.Sqlite3main = do
conn <- connectSqlite3 "test.db"
r <- quickQuery' conn "SELECT * FROM testTable" []
let stringRow = convRow $ head r
disconnect conn
convRow [_, _, sqlDesc] = fromMaybe "nothing" (fromSql sqlDesc)
It's either in the quickQuery' or in the convRow function (fromSql), but I'm not sure what to change. HDBC supposedly has unicode support, I wasn't expecting having to change anything.

why?
++c should increment c and return it. right?

Because the compiler puts the extra 1 for good luck.

If it was undefined, then the program would abruptly stop with a run time error, just like when using integer division with 0 as the divisor. This doesn't cause a run time error, so it is defined. You're just stupid.

Text.
I changed it a little to debugconvRow _ = "unexpected result öÖöë"
And it's displaying the umlauts correctly.
I think the problem is herer <- quickQuery' conn "SELECT * FROM testTable" []
Doing :t quickQuery' it says:: IConnection conn =>
conn -> String -> [SqlValue] -> IO [[SqlValue]]
So I think the query itself is returning the row as a string and putting that inside the SqlValue.

The compiler used a 1-based array for your array of ++ operations, which is why there is one extra.

>questionable behaviours
Why exactly?
Refactoring rather than search / replace makes it much safer and since I am bad at naming things.
Opening a lot of files in tabs is not bad behavior either unless you have no resources left on the system.
Jumping from a function call to where the function is implemented just saves time and makes it easy to see how the function is implemented / what the parameters is needed.
The reason you use an IDE is mainly to read code.
Vim seems to agree with that since most vim is not optimized for inserting text.

Anyone know matlab? I want to crop this black square and save it as a new pic. I pasted this code together from stuff I found online. I identified the black square, how can I save it as an image itself?img = imread('test2.jpg');
bw = im2bw(img);
imshow(bw)
% find both black and white regions
%stats = [regionprops(bw); regionprops(not(bw))]
stats = [regionprops(not(bw))]
%stats = [regionprops(bw)]
% show the image and draw the detected rectangles on it
imshow(bw);
hold on;
for i = 1:numel(stats)
rectangle('Position', stats(i).BoundingBox, ...

end

add the assembly as a reference, then use the library as you would normally use the inbuilt classes
Simple question, interested in getting some other opinions.

Well I'm already doing that. I simply can't access global functions. They are not located under the namespace while the documentation mentions them. I can access all other available classes and instantiate them.
>>51268477
in the ferences list, right click the assembly, and click View Object (or something similar)
it takes you to a listing of the assemblies loaded
expand your assembly, and you see all the namespaces.

You're not going to get anyone interested with that, unless you're trying to keep it super simple to explain the code?
Even then, get a cool complex program to show them what they can do in the future if they join. Hell, pull a bait and switch and show them something really difficult that not even you can understand, if they ask about it tell them they wouldn't get it yet.

>Refactoring rather than search / replace makes it much safer and since I am bad at naming things.
Refactoring support is not bad for refactoring code in a "project" (whatever that means). It doesn't refactor comments. Search and replace is good at updating comments while you refactor in a single file, but can't do anything across libraries where naming could be all over the place depending on the language.
>Opening a lot of files in tabs is not bad behavior either unless you have no resources left on the system.
It's a sign that you have a spaghetti design that was enabled by an IDE. This is one of the many reasons IDEs are considered harmful even though every single one of their features are actually good.
>Jumping from a function call to where the function is implemented just saves time
There is no way for a text editor to know this since in some languages a function can be declared multiple times but defined only once and the language offers no resources for locating a definition.
>Vim seems to agree with that since most vim is not optimized for inserting text.
We will disagree on this point, but it doesn't really matter. Either you agree with the philosophy behind writing code in such editors so you use them or you don't so you don't use them. I have nothing against IDEs for good code but there is no question that they also are terrible enablers for shit code to still be maintainable due to their enhanced feature set over otherwise robust text editors.
>>51268374
Wow, people are actually discussing the trollcode!
>>51268374
It also happens when I just increment twice.
I don't see how this is undefined behavior though.
if you call a function twice in the same line, each call is executed as they were called one by one.#include <iostream>
int inc(int &c){
return ++c;
}
int main(){
int c = 5, d;
//d = ++c + ++c + ++c + ++c + ++c + ++c + ++c + ++c + ++c + ++c + ++c + ++c;
std::cout << d << '\n';
c = 5;
d = inc(c) + inc(c) + inc(c) +inc(c) +inc(c) +inc(c) +inc(c) +inc(c) +inc(c)+inc(c) +inc(c) +inc(c);
std::cout << d << '\n';
}
The second returns 138 as expected.
But adding the last bit also made the first bit print 138...
I don't see why.
