Currently Trying to figure out how to manage game states in spples. At the moment I have:

class GameStateManager {
    // ...
public:
    void Run();     // Does main loop, manages frame rate and tick rate. Calls Update and Render of the current GameState
    void SetGameState( GameState *nextState );
    GameStateManager& GetInstance() { return instance; }

private:
    static GameStateManager instance;
    GameStateManager() : currentState( nullptr ) {};
    GameState *currentState;
}

class SomeGameState : public GameState
{
    // ...
public:
    void Render( RenderTarget& rt ) override;
    void Update() override;
    SomeGameState& GetInstance() { return instance; }

private:
    static SomeGameState instance;
}

And I feel extremely Indian becuase it looks like something an """OOP expert""" would do in Java (everything's a fucking singleton!). This is poo. Then again, how else to do it? Having to instantiate GameStateManager or GameState derivates locally seems impractical, since GameStates must be able to transition to other GameStates:

void MyGameState::Update()
{
    // ...
    if (health <= 0) {
        GameStateManager::GetInstance().SetGameState( GameOverState::GetInstance() )
    }
}

One alternative I found is to save all possible states into a map inside the GameStateManager at initialization time, so they can be switchen via something like

GameStateManager::GetInstance().SetGameState("GameOverState")

-- so that's the GameState singleton gone. It's still shitty though, since having a hash map inside the manager just to save the states seems extremely wasteful and horrible to refactor, in case I want to rename a game state, or I make a new state and forget to add it to the map or something.

(Or is this maybe one of these very few and far between cases where singletons are okay? plsnobully)

>>56819285

Just use Node. It's faster than PHP, and Javascript, while rather shitty, is less shitty than PHP.

>>56819403
Yeah, I've been going thru benchmarks, I was put in my place I guess. Still I'll try to do it with least libraries. Thanks bby x

>>56819403
>while rather shitty, is less shitty than PHP.

I'm trying to come up with an analogy to it being infinitely shitty, but less shitty than an infinitely shitty alternative.

>>56819395
>Health a part of SomeGameState
Make it a separate object, in fact, make all of the state encapsulated by the GameState a separate object.

You could call it a component.

>>56819300
please be baiting

>>56819451

PHP shittiness is like ω^ω
JS shittiness is like ω^k for some arbitrary finite, but sufficiently large k (for instance, k = Graham's number might be a rough approximation)

How do I initialize an extern multidimensional vector declaration?

extern std::vector< std::vector<MapData> > mapData(std::vector<MapData>);

I'm trying whit this but I get error: ‘std::vector<std::vector<MapData> > mapData’ redeclared as different kind of symbol

std::vector< std::vector<MapData> > mapData(MAP_X+1, std::vector<MapData>(MAP_Y+1));

>>56819552
Java

>>56819459
>Health a part of SomeGameState
Just a flawed example. I wanted to show that the current game state can be changed from really anywhere.

>make all of the state encapsulated by the GameState a separate object
>You could call it a component
Indeed I'm working on a component-based game engine, becuase any other architecture is just doomed to fail at some level of complexity. However, this won't solve my "problem" of managing different game states in a potentially subpar way. For example, I'd still need different states, one for rendering and updating the main menu, one for the "actual game", one when the game is over etc. or nah?

>>56819552
>What language should I learn if I need to make a little money fast.
Well, there is always some company looking for Java devs...

>>56819597
without seeing both the file where its defined and the file where its declared i cant say, however i believe what you're doing is declaring it a 2nd time.

normally you define a variable in someFile.cpp

int foo = 42; 

and then in anotherFile.cpp

extern int foo;

void bar(){
    std::cout << "foo: " << foo << std::endl;
}

note that you dont initialize it again, you just declare it in other files using the extern specifier

>>56819395
>refactor
you shouldn't have more than a few game states like pause/playing/intro(when booting the game)

>>56819643
I think that I found the solution, it's supposed to be declared like this:

extern std::vector< std::vector<MapData> > mapData;

>>56819668
youre right. i should have paid closer attention.

when you declare a symbol as extern, you should NOT be passing it constructor arguments. it has already been constructed in whatever file it was defined.

So I heard that the reason for the dominance of C and C++ is due to the amount of boomers in the industry.

And that employers actually want young employees to know new languages, like Ruby and Ruby on Rails.

But I have yet to find a single "Junior Ruby developer" position in my field.

>>56819686
t. pajeet who doesn't know loose coupling and encapsulation

>>56819697
The reason is that C/C++ is the default language when it comes to a lot of lower level things, e.g. all Engineers use it or at least learn it.
If it were for boomers we would all program in COBOL and Pascal.

>>56819697
C/C++ is not "dominant" in jobs.

Java has the most by a large margin. C# is the next highest, well above C/C++/Python which are about the same.

Javascript is essentially ubiquitous, as is SQL.

Ruby really doesn't have many jobs in comparison to any of these.

>>56819722
That only works 100% in an ideal world.
In real world someone else makes mistakes(or even just changes) in his code that dont affect him and you will cry on /g/ why your code dosent work while analyzing your code for weeks until the other guy fixes the problem.

Not categorically right, no.

There are good programmers that don't know any of those languages.

There are horrible programmers that can use all of those.

You should figure out what you want to program, and select languages that suit those needs and compliment each other.

HTML/CSS should be included in every "junior developer starting pack", together with Javascript.
You do need some webbased stuff.

I'm gainfully employed in a software development role and I've never touched JS, HTML, or CSS.

That being said, knowing these things absolutely does open up a massive swath of job opportunities, but they really aren't necessary.

>>56820157
"webservices" is vague. What exactly are you trying to say with that?

Retard here,stuck on two things, any examples/help would be appreciated. I'm trying to use a class simply as an entry point, then a second class performing the task. My problem is, when I'm running the first class, nothing happens. Running the second class by itself works fine.
First class:

 
public class ModuloEntryPoint {

    public static void main(String[] args) {
        new ModuloPrint();

    }

}

Second class:

public class ModuloPrint {

    public static void main(String[] args) {
        
        for (int i=1;i<=70;i++) if (i % 5 == 0) System.out.print(" "+i);
        System.out.println();
    }

}

Also, is there a way for me to print the modulo loop using something like System.out.print(moduloLoop()) instead of having the "for int" before the print?

In your second class use a constructor rather than two mains. That's when it's instantiated.

>>56820928
>>56820975
As in, call a method or use that for loop in the constructor. Right now the class you're running is the entry poiint, and obviously simply instantiating the second class from the first does nothing.

You could put the loop into a method and call new ModuloPrint().method();

>>56820932

Javascript shitter coming through, don't get my filth on you as I ask this peasant-tier question:

Express.js question:

I want to do nested iteration in the pug template engine (formerly known as jade).

I have an array of objects. Each object within that array contains an array of objects. I want to render a specific property from each nested array to the screen. I think my code is correct, and yet nothing is happening. It's not throwing an error, it just doesn't render anything in the div these properties will be inserted into.

- var i = 0
  while i < outerArr.length
    - var j = 0
      while j < outerArr[i].length
        .col-xs-12.text-center

>>56821676
Here's a weird thing:

I tried reformatting it to use a for loop instead of a while loop. It works to a certain extent. I could print outerArr[i] to the screen. However, if I attempt to access a property on the currently iterated object (e.g. outerArr[i].username), it throws an error: "cannot read property "username" of undefined". Which is nonsense, because it was defined just a second ago.

I dunno why this is such a pain in the ass to get right.

>>56821724

>i want to know why i can't use strcpy_s
AFAIK there are 2 variants of that function. One that takes a statically allocated string (as in

char str[1024];

, and one with 3 parameters, where the second parameter is the length of the destination string. Since you don't appear to be using statically allocated string, maybe you used the wrong overload. Have you tried

strcpy_s(out, out_length, result.c_str());

? (Note that you'll need to know the size of 'out')

If you'tr one hundred percent sure that all you do is safe all the time, you could

#define _CRT_SECURE_NO_WARNINGS

to silence the warnings.

>when using strcpy might be bad
When you don't know the size of your destination string, and you blindly strcpy into it. That's bad because the source string might be longer than the memory block the destination string was allocated for.

Yes and no.
If you want to find out more about why OOP is terrible in many situations and you want to explore alternatives, then there are better ways to do so.
If you want to completely throw every kind of paradigm overboard and want to learn how programs work at the lowest level, then yes (if you don't mind spending one afternoon or another debugging a singgle function occasionally). At times I find assembly quite fun, since I learned a lot just about how things really work, and it definitely made me value performance optimization a lot.

I actually would like to go deeper and learn assembly some time in the future, but right now i don't have the time, patience nor motivation.

Date and Calendar. Date a) is a wrapper for timestamp rathe than actual date and b) is very basic. Calendar tries to solve every use case with it's multiple time systems which makes it very confusing and heavy for most use cases and it still doesn't work for all date systems around the world.

Also there are some related classes which complicate it further like Instant, LocalTime, LocalDate, MonthDate etc.

Ironic, because the GoF patterns are almost always things that are so trivial that they are not even worth noting if you are in a functional language.

If you consider OOP to be a tool to be used when appropriate instead of a paradigm. Under that definition, my argument is that OOP is almost always inappropriate. Same thing, really.

>Enumeration and Iterator.
Never heard of Enumeration before, never seen anyone use it anywhere, including standard library.
>Date and Claendar

I agree that they are bad, but I think it was pretty much standard to use external library for dates like Joda Time. That was before Java 8 of course, which brought very clean date api.
>Yes, but that still isn't a valid excuse for keeping them in after all these years. JDK team really should start doing some spring cleaning in their APIs.

>>56823124

The thing is that anti-OOP arguments are predicated on the purveyor's opinions being axiomatic in some way. For instance a common argument is that inheritance is ill-equipped to model real world hierarchies. Well, says who? Some contrived example isn't good enough. Another frequent argument is that the whole noun-verb model of objects and methods is incapable of modelling interaction BETWEEN objects in the real world. Once again, says who?

It's literally contrived examples all the way down.

I'm not saying that OOP is the greatest thing to ever happen to program. I'm not even saying it's all that great. I think multiparadigm is the way forward, because it blends imperative, OOP, functional, etc. styles when they make SENSE to be used. With that said, he whole "OOP IS GOOD FER NUTHIN!" meme seriously needs to die, because it's stupid and the people who believe in it are universally buttlickers.

>You cannot even make a GUI without libraries, so I guess truly "knowing" C++ includes knowing Qt
truly knowing C++ doesn't technically require knowing any libraries (it definitely doesn't require knowing Qt - there are much leaner/simpler GUI libraries, by the way). not knowing libraries just might limit what you can easily do

>C++ without libraries is not that much, actually
it... kind of is. you might want to try "going deep", as you say. you might find it's a deeper rabbit hole than it looks. make sure you're reading modern material, C++11/14 really changed the game. everything you don't know is either something you're missing out on, or something that's gonna bite you in the ass

Stack is old version of Deque, Vector is old version of ArrayList and Hashtable is old version of HashMap. They were really badly written and you had to use custom code to access them if you wanted decent performance. When adding the new collections Java devs put them as seperate classes and left the old ones intact because of that custom coding which doesnt work with the better designed classes.

>Never heard of Enumeration before, never seen anyone use it anywhere, including standard library.
It was the old version of Iterator with worse method naming and no support for optional add/remove functions.

>because it's stupid and the people who believe in it are universally buttlickers

not an argument.
that said, OOP IS GOOD FER NUTHIN!

>>56823252
>You can do OOP in C.
This simple fact really triggers some people.

goddamn I'm pretty sick of the anti-OOP circlejerk that has been particularly bad the past year or so.

why is it that 99% of enterprise code is object oriented? why...why is that?

>>56823245
If you want to see the problems with OOP, read GoF

>>56823216
None of them.

Java has Swing.

>>56823216
I don't know about the others, but OpenGL is availible in java in form of LWJGL, but it's for 3D graphic, not for GUI.

>>56823222
>C++ isn't "C plus OOP".
Quite right. C actually allows you to write a proper dispatch system that isn't a static table you can't touch for little to no reason for example.
And it doesn't have a bajillion side-effects as a consequence of an utterly retarded design committee.

Mkay.
Mind giving me a book or tutorial link? And an example of what I might be missing out?

I didn't say OOP was infinitely powerful or expressive. I know that design patterns are a result of limitations.

>>56823268

>>56823259

I can't think of any, and if I did, they would be just as contrived as the arguments AGAINST oop. The simple fact is that real software is more nuanced.

>>56823252
What people mean by OOP varies by language desu.
C++'s "OOP" is quite easily the most cancerous one though.

>>56823259
polymorphism.

you have 100 types of enemies in a game, they all use similar moves.

>>56823281
JavaFX is the current API.

>>56823275
OOP is really good for pajeet-tier programming. You have a simple interface that has simple methods. You dont need to think or invent anything new, just connect the dots by moving and returning variables. When you hear about AI replacing programmers it's this kind of work that is being replaced.

>>56823275
>why is it that 99% of enterprise code is object oriented?
Probably because you're working with GUI's and other shit whose libraries force you to resort to a OOP style and whose models aren't utterly brainbreakingly terrible.
The second you have to do something that requires real performance any idiomatic OOP flies out the window fast.

>>56823310
OOP isn't just not infinitely powerful or expressive, it's EXTREMELY LIMITED in its power and expression.
OOP, especially in C derivatives, is extremely brittle and poorly composable.

>>56823337
That's just code reuse, not specifically polymorphism. Do you really think OOP is the only thing that nets you either of those things?

>>56823310
Thanks mummy!

>>56823374

That's not an argument.

>>56823260
>truly knowing C++ doesn't technically require knowing any libraries
I disagree. I would claim you need to be familiar with stl to be able to claim knowledge of C++.

>>56823345
>The second you have to do something that requires real performance any idiomatic OOP flies out the window fast.
not really, you pack related data into structs ("objects") and you have related functions/methods which operate on the data

>>56823337
All of which will be different and should probably reuse code in lieu of setting up retarded hierarchies.
If polymorphism in game development is used it's generally as a huge entity blob which all entities are composited of.

>>56823282
If you can do 3D, you can do D2, and if you can do 2D you can do GUIs.

>>56823429
using opengl for GUI is retarded, only ok for games and games typically have very rudimentary start menus

>>56823261
I don't know what century were last you coding with java but thing like ArrayList are here since java 1.2.
The devs had to leave the old classes because of backward compatibility, but I don't see how that's a bad thing since everyone uses the new classes anyways, which are clean and well documented.
The only case that would be bad is if people were using both, like in case of swing vs JavaFX which was your only valid argument.

>>56823314
What people mean by OOP varies by individual. It seems no one can actually agree on what OOP is, when pressed on the matter.

>>56823429
You also can code a webapp in assembly but you don't do it, because it's fucking stupid.

>>56823487
coding a webapp in assembly is several orders of magnitude more stupid than coding a gui in opengl.

>>56823245
inheritance isn't particularly useful because it allows overriding.
overriding results in a sub type relying on the concrete implementation of the method it's overriding, not just the api and the abstraction
the fragile base class problem, basically.
encapsulation is a useful thing, no doubt.
having a special syntax for stateful functions (methods) isn't that bad either.
what's bad is attempting to throw problems that can be solved without state escaping the function into an object.
you end up with the same syntax for both stateful and stateless computations and the advantage of having two seperate syntaxes is ruined.
if you use OOP within these boundaries (encapsulation to expose a consistent API and to hide both state and implementation, classes + methods instead of functions only when the class needs to encapsulate state, composition instead of inheritace) then oop is completly fine.
i'd also be fine with using a class with no state to use interfaces as a collection of function types, if the language has no construct for that.
the real issue at hand is the way oop is taught at school: a silver bullet to software architecture by supposedly making all code more readable by using objects to turn normal code into code that follows the "subject verb object" structure.
using patterns blindly is also an issue, because it often complicates the necessary abstraction a lot more just to add redundant extension points that'll never be utilized and to make the code look more like english.
the same goes for using inheritance: it's taught that inheritance is a silver bullet to model hierarchies, instead of teaching it as just another type of abstraction with pretty strong limitations.
ruby is an especially contrived example where the idea of code having to look like english went rampant.

you should definitely know the STL, i figured that was a given

>>56823594
then agian, this opinion might be slightly tinted by the the fact that i know a bit of OpenGl, but not assembly.

Do you ever decide to ask a question, but by the time you're done typing up the post you've realized all the replies, sou you just don hit post?
