Reminder not to give up.

If you feel stuck and about to give up, take a break. Play vidya or watch some anime, come back tomorrow and start over from scratch with the problem.

>>14595747

Take breaks. Breaks are good and often good for ideas.

Look into proper computer wrist posture. It sounds like yours is wrong. Don't continue working, or you'll risk fucking up your arm with potentially permanent nerve damage. What angle is your wrist at when on the mouse?

>>14595754

>triggered about anime in an imageboard

Please tell me I misunderstood

>>14595847

place something under your wrist, like a rolled up towel etc.

you probably cutting of circulation by pressing against the desk

i had the same problem and thats how i fixed it

>>14595847

Your wrist is resting on the desk, which is probably putting pressure on nerves, tendons, and blood veins, which is probably what's causing the problems. Keep your wrists off the desk and as neutral as possible. Put your chair and armrests in a position where both your palms and wrists are slightly above your keyboard and mouse. If you're having trouble keeping yourself to it, get a soft wrist support.

First for C++ as "C with lambda expressions"

>>14596742

That's C#

>>14596814

Java has all the pajeets, notice how no one using C# is clamoring to remove primitive types

Reminder to stop optimizing prematurely.

Use a profiler if you want to know what takes too long in your code and optimize that first.

Stop fussing over shit like "if-else or ternary operator" or "++i or i++".

The compiler is a LOT cleverer than you when it comes to optimizing low level shit.

I do this shit for a living

>>14596853

But muh switch statements

>>14596853

what are you? a freelance code optimizer?

>>14596853

Having actual self worth is the biggest factor that distinguishes whether you publish a quality game or unpolished dogshit. This is why lefitst games are always such garbage, not just because they inject their pathetic ideas into them. If you willingly publish shit, you have no self-respect or worth.

You can't do anything novel without knowing precisely what your code is doing, and if you try to do so you'll produce shit (and again, have no self respect)

Understanding what your code is actually translating to is an important part of actually producing something good. You're repeating dogma. Compilers are retarded, they miss trivial optimizations unless you specifically phrase something in a way you know the compiler will translate to something else.

>>14596881

This guy's smarter than a compiler

>>14596853

Reminder that this is generic dogma that you tell faggot newbie programmers that get bogged down in low-level optimizations. Always consider high-level optimizations when designing your code and set target platforms/performance to know when enough is enough.

>>14596898

Perfectionism is a real danger in coding. He's saying to focus on getting results first and do optimizations later.

>>14596907

High-level optimizations are expensive to do after the fact, which is why it's important to always have in the back of your mind. Changing your architecture sometimes ends up impossible without rewriting the entire thing.

>>14596881

>Understanding what your code is actually translating to is an important part of actually producing something good. You're repeating dogma. Compilers are retarded, they miss trivial optimizations unless you specifically phrase something in a way you know the compiler will translate to something else.

Understanding what your code is actually translating to is important if you want to grow from a decent coder to a good one.

Many people here are just starting out. Telling them to look at assembly would be bullshit.

Optimize when there is need to, not before.

>>14596898

Exactly.

>>14596875

senior dev, automotive industry (think self-driving cars), the software has to cope with GB of data per second, so it has similar performance constraints like games. Also did VR engine development before.

>>14596914

True, but as >>14596907 said, one should aim for the middle ground.

>>14596894

>>14596911

>write some code

>look at what it compiles to

>reorder it with the exact same functionality

>it compiles to better code

If all you can do is regurgitate dogma at me, then you're clearly operating at a level where cookie cutter advise meant for the masses applies to you.

>>14596919

>True, but as >>14596907 said, one should aim for the middle ground.

I'll be honest, all of the games in Aggydaggy could trade performance for productivity and be better off. My game for example really only uses object pooling and resource caching as 'optimizations' (being generous here), it doesn't need more and I doubt many other games here do either.

>>14596921

>write some code

>look at what it compiles to

>reorder it with the exact same functionality

>it compiles to better code

The third step might also actually be

>reorder it and think it has the exact same functionality, but actually does something slightly different

in some cases.

>>14596853

>Reminder to stop optimizing prematurely.

Platitude fam. "Prematurely" is too context sensitive. Besides, optimizing is fun

Here is a good talk about optimization.

Important part: 42:25

>>14596943

The compiler can't optimize when it can't make assumptions. I've seen an example where adding a seemingly extraneous modulo made the difference between concise SIMD and a large amount of edge case handling. That said, >>14596881 comes off as an idiotic amateur who thinks he's an elite programmer because he found his mistakes with a disassembler when he could have found them thinking about his program a little harder.

Can you make actual games with Pixel Vision or is it just for fun?

>A downloadable Fantasy Game Console for Windows, macOS, and Linux

It's for developing games with console specific restrictions (like Famicom, Gameboy and a few others) or custom settings. From the description I can't gather if it's just for simulation of developing games with those restrictions and the game is just playable on Pixel Vision or if you can make a product.

>Easily share games with others as .pv8 (.zip) files.

I'm not sure if this means, share the games with all people or just people with Pixel Vision.

It's in alpha and look at the comments section, doesn't look great, what do you want to make?

I suppose you can make games then. And yeah, I've found out about it from their recent twitter announcement. They seem active. Thanks for spoonfeeding by the way.

>>14596957

The other cases are defined to be undefined behavior in the language. The compiler is doing exactly what it should here, and complaining that it isn't optimizing undefined behavior in a way you intended shows that you clearly don't know the language you're writing in.

>>14597394

Do you even understand what you've written?

>>14597436

There's no one to use it, anyone who can make an art style work will make an actual game. Everyone else will just use "Free low poly asset packs for Unity"

>>14597436

You could just make a low poly game in c with commonly used libs to make a game which runs on a raspbarry pi.

Consoles WERE ALWAYS SHIT!

>>14597362

I've heard of Love but I've not looked into it. Will keep in mind.

>>14597436

Would be interesting as a shorthand. I always wanted to make a game with a jittering ps1 look.

>>14597436

The only reason Pico 8 is successful is because it has all the tools integrated into it, and games are easily distributed (as an embedded .png)

Basically if you can define a simple format, make a toolset for it, people will probably(?) go for it. But at that point, if it's so simple and extensible, why not just let them use a language of their choice like C# or Lua, and then at that point, it's not really a console

>>14597448

>anyone who can make an art style work will make an actual game.

Yeah, but you could argue the same thing for many of the other fantasy consoles. PICO8, LIKO, and that Pixel Vision all have decent communities because people like working on platforms with strict limitations. You could make identical games with Love2D or any other graphics library, yet for some reason people opted to use the fantasy console for their games. The low-poly unity shitters on the other hand can't be helped; they'll be doomed to make low poly garbage games with the "unity look-and-feel™."

>>14597480

I do have a few pi's and that could be an option. But I've been writing a cpu emulator as a side project and would ultimately like to do something cool with it, like make a fantasy console. Or I could just make a game.

>>14597394

How on earth are you reading undefined behavior into this?

I meant shit like coding

if(complicatedFunction() || simpleFunction()){
    foobar();
}

Then reordering it to

if(simpleFunction() || complicatedFunction()){
    foobar();
}

and thinking it's the same code.

>>14597499

>But at that point, if it's so simple and extensible, why not just let them use a language of their choice like C# or Lua, and then at that point, it's not really a console

I mean if you look at it that way, the PICO8 isn't really a console either. It's more like a Commodore64 with built-in dev tools to make games, but I see your point.

>>14597506

For those of those that don't know, the binary || will evaluate the first function and only continue if it fails. If it succeeds, the second function is never called. Thus, it makes more sense to call a simple function/one that is likely to succeed, then || it against a slower or more complex function

>>14597518

Thanks for adding that, anon!

>>14597492

Also, don't fall for pixelshit memes.

By restricting yourself to using less colors the amount of bytes actually used is the exact same as if you used the full color space available.

I wouldn't use or recommend pixelvision tbqh since I don't think the license allow to distribute the script with the engine which means that you can't make executable files like you probably envision.

>>14597500

>Yeah, but you could argue the same thing for many of the other fantasy consoles. PICO8, LIKO, and that Pixel Vision

No, you couldn't, because any random idiot can make a shitty 2D game by copying and pasting Lua scripts into a fake console. I suppose Unity isn't any better in this regard, but you can always tell indieshit low poly "art" from a game made by an actual team of competent developers with self worth

>>14597506

Wups. I was looking at >>14596911, don't mind me.

>>14597543

Actually when I tried to make a light flow thing for a roguelike, I researched a few different systems, and saw Source's approach which did the same thing.

The reasoning behind it was that using A-Z, you had 26 different values (A=0, Z=100%) to scale the lighting. This let you express complex light patterns in single characters as a string. Think of it as a helpful macro instead of creating a byte[] or a manually typing, eg 0x0, 0xF, etc

>>14597584

I don't know what the result of "bool+bool" is in C/++, but each component in the if statement will be evaluated. Each function call will call printf with "true" as the argument, therefore the output should be:

>called with: true

>called with: true

and do nothing otherwise, correct?

>>14597601

Now we modify the code thusly

#include <cstdio>

bool check(bool v) {
    printf("called with: %d\n", v);
    return v;
}

int main() {
    if (check(true) or check(true)) {}
}

What does it print now?

>>14597608

>thusly

this is ironic, right?

>>14597608

Is "or" even a valid C++ operator?

>>14597608

Well it should only call printf() one time now, since the first call to check() returns true, and it will stop evaluating the condition because it found a true value

>>14597615

We'll assume it is for the sake of whatever argument he's making

>>14597622

>We'll assume it is for the sake of whatever argument he's making

But what operator does he even mean? | and || are both "or" operators, yet their behavior around this case are different!

Last variation!

bool check(bool v) {
    printf("called with: %d\n", v);
    return v;
}

int main() {
    if (check(true) | check(true)) {}
}

What will the output be?

Quick, what does[code]int i = 5:

printf("%i", i++ * i++ * i++);[code]print?

>>14597605

Very cute. I personally think the jump could stand to be slightly higher, but the controls are great overall. It has a good feel to it.

>>14597615

these bitch niggas gotta learn evaluation rules, and what short circuit operators are, and how they evaluate compared to bitwise logic.

short circuiting sucks in C if you use it in a value context like lisp.

x || y
in
c semantics: (x ? 1 : (y ? 1 : 0))
lisp semantics: (x ? x : y) [roughly]

>>14597651

15?

sequence points are after expressions.

>>14597648

Called twice because it needs to evaluate the function to compare two bool values (true bitwise-or true) to get a final value (true) to see if the if body is executed

>>14597651

Not sure offhand because this is the style of coding I usually avoid. Depends on the order of operations, but I assume (probably incorrectly) that it's 5*6*7=210

>>14597693

Oh shit I was right, good feels.

>>14597912

Yes, anon?

>>14597893

if it's just buttons I would not bother with a more complex data structure like a quad tree It is just buttons, right?

>>14597922

Yes. Really they don't need to be anything more than a boundary, but more specialized Control classes will probably add more stuff to them.

I'm trying to make a simple UI library on top of SFML that I can use for my games. Allowing for rendering is going to be the hard part, but the functionality should be more or less be straightforward.

One thing I have difficulties conceptualizing is something like a scroll bar or a spinner box. Would the control itself create two additional buttons for increase/decrease and parent them to itself, or would they just be additional pollable regions?

>>14597931

Oh actually, since UIs are tree based by default, I only have to step deeper and check the children if the parent element contains the XY position. That's great, even if I have a million controls, only a handful have a chance of being polled that way

>>14596911

What's the context of this clip? Assuming x is a number, why wouldn't that if statement successfully evaluate to false?

>>14598109

It's a clip from a hacker expo. Despite being a shitty Las Vegas pozzed shit, they do know a fair bit of things

https://en.wikipedia.org/wiki/DEF_CON

I assume in this context, evaluating it when X is equal to the maximum value, X+1 will overflow into either 0 or -2147483648. Therefore, if as an end user can supply "2147483647" as an argument, it will roll over and evaluate true, and in all other cases will evaluate false

>>14598109

It was from a video about hacking MMOs.

The video has since been taken down after a copyright claim from one of the game publishers featured in the video.

>>14598109

>Assuming x is a number, why wouldn't that if statement successfully evaluate to false?

Suppose X is an 8 bit integer whose value is 255.

>>14598132

>I assume in this context, evaluating it when X is equal to the maximum value, X+1 will overflow into either 0 or -2147483648.

IIRC this is actually undefined behavior. There was some shitbreeze over it when one compiler actually treated it as such and optimized that kind of thing away.

>>14598148

this problem is easily solved by removing primitives entirely and using rationals for everything; In this case, 'X' is a class that inherits from a rational integer, which is backed by either a fast numeric type (hidden to the user) and gracefully and robustly instantiates a proper rational if its out of the integer range. Alternatively, don't use bytes, this is 2018.

Yeah. It's really annoying hearing that though since, like Mike Acton says in the vid, "It's the most abused quote ever". I remember running into this situation a lot:

>Starting a new system in my game

>Think of something (algorithm, container, etc) that will be used all over the system and could be done god knows how many times per frame

>Decide to research it just to make sure I don't structure an entire system on something that is slow

>Have to dig through "Don't prematurely optimize"

>>14598290

Assuming this actually happens: who will not only set all of it up to run on a pirate server, but also get a team to actually implement the stuff you want?

>>14598202

Don't feel bad. Microsoft programmers made numerous overflow errors in Windows Defender when they "borrowed" some open source code, closed the source, and then converted all integer variables to signed to get rid of annoying compiler warnings.

Programmers are the most dogmatic group of people I've come across.

Oh you'll love this. After you write your shit you can run it through an obfuscator that basically renames symbols into gibberish to make it hard to reverse engineer.

But also, Java has import. It normally works on class references as a whole but a static import lets you pull individual functions

>>14600144

I think deobfuscators try to consolidate the millions of useless classes and getters/setters into the actual program, so it'd at least be handier than searching through 200 files

Unless your game is strictly a free hobby project, you're going to have to worry about project management and things like marketing and funding eventually.

Godot 3 yeah. It shouldn't be graphically intensive, 2 lights at most at a time and 1 particle effect and pretty streamlined otherwise, except for it using gdscript and when running in the editor.

You could have a look at rendering a dynamic skydome using physically accurate models, starting with an accurate atmospheric model. People did shit like dynamic day and night cycles where the way the sun and moon appear on the sky at any given time is actually astronomically correct. Some even show the actual night sky with the star formations in the right places depending on where you are on earth and at what time. Then there's rendering photorealistic volumetric clouds, which looks super cool, especially when you can fast forward and have dynamic lighting.

I don't know how involved all of that is though. Rendering a realistic atmosphere isn't that difficult from what I heard.

Here are some examples:

What are you doing a minecraft mod? Or your own minecraft clone?

>>14605728

I'm basically rewriting minecraft's deobfuscated code.

>>14605735

If you're hardcoding it just do a switch statement or a series of if then else statements. Similar thing if you're loading in block data

>>14605744

It's not that easy, or at least it would be if I was using multiple blockID's.

quantityDroppedWithBonus checks if par1 is greater than 0 and if blockID != idDropped(0, par1, par1Random) before doing anything, then it calls quantityDropped, which checks if blockID is equal to lapis ore, and if yes it drops 4 + random.nextInt(5)

else it drops 1

I can't figure out how to apply this to a block's damage value because that itself is not hard set anywhere, there's no variable to call, I thought I could cheat by calling blockIndexInTexture but it always returns the default texture value, despite it having to use a different texture based on the block metadata

What are your ways of getting motivated?

>>14605775

Wouldn't you be able to add a class field (int) for block metadata?

>>14605797

Beats me, there's a method for returning the metadata (damage value) of the block when harvested. Actually maybe it would be doable to add subtype as an int to the protected block constructor, and assign the metadata instead of a blockID. I'd have to try that out since that seems better than doing all this within the block class.

>>14605825

So I just saw your OP, it provides some context.

>>A vector does not store its data in a continuous chunk of memory.

No.

C++0x upwards states:

n2798:

"23.2.6 Class template vector [vector]

1 A vector is a sequence container that supports random access iterators. In addition, it supports (amortized) constant time insert and erase operations at the end; insert and erase in the middle take linear time. Storage management is handled automatically, though hints can be given to improve efficiency. The elements of a vector are stored contiguously, meaning that if v is a vector where T is some type other than bool, then it obeys the identity &v[n] == &v[0] + n for all 0 <= n < v.size()."

ISO 14882, 2nd Edition: Section 23.2.4 [lib.vector]:

"The elements of a vector are stored contiguously, meaning that if v is a vector<T, Allocator> where T is some type other than bool, then it obeys the identity &v[n] == &v[0] + n for all 0 <= n < v.size()."

>>An STL vector always allocates memory for its data on the heap. Heap allocation is slower than stack allocation.

Well no shit, stack memory is precious and small, you don't pack a vector with possibly millions of elements into there.

>>14606661

can the bonus points be exchanged for food?

>>14606655

Oh, I think he meant the vector data and the begin/end are saved at different positions in memory.

Well, who cares about that?

…

Also his point seems to boil down to that you have a certain overhead due to the heap allocation, which could be bad if you keep allocating vectors inside of a loop.

Well, how about you don't fucking do that?

Create it outside the loop, resize appropriately and fill/refill the data each iteration, like a normal human being.

>>14606672

Cut him some slack. This is typical thinking of someone coming from one of the "managed" languages. Dealing with memory allocation efficiently just isn't a skill they have yet.

But yes. No memory allocations should be happening inside loops. Or on a per-frame basis. This is what ring buffers and container resizing are for.

I made pretty good headway with these concepts when I wrote a particle effects system in C. You don't need to write your own custom malloc() for everything, but you should at least be re-using arrays with custom offset pointers/index if needed.

>hidden costs

There are three possible angles here.

1) If you use STL code, the costs in big O are known.

You shouldn't be surprised the lookup in a map is slower than in an array.

But this is tied to the algorithms and also not inherent to the language, so I wouldn't call that hidden cost.

2) If you have foreign code (from dependencies/libs/other people), well shit of course, I have to look at their code (or preferably documentation) to find out if its costly or not.

This is the same for every language, so this is also not a hidden cost, that only C++ has.

3) Remains the third case: Your own code.

If you code

ExpensiveObject doSomething(ExpensiveObject obj) {
     ExpensiveObject ret;
     ret =  ExpensiveObject();
     ret.foobar = 1;
     return ret;
}

instead of

ExpensiveObject* doSomething(ExpensiveObject& obj) {
     obj.foobar = 1;
     return &obj;
}

Then, yes, there are "hidden costs" in the sense of "fuck up and everything might be more expensive than you think."

But I would call that "not knowing the language (that well yet)" and not make it C++'s fault.

Yes, it is harder to see what is going on, performance-wise, since there are a lot more possibilities of what can happen.

But I would argue that this is a small price to pay for much more robust code, that abstracts a lot better.

The more complicated your program gets, the more you want to have that level of abstraction.

The author writes it herself:

>>That is the hidden cost. The mental model for a simple function call became incredibly large and complex, and every function call is potentially as complex. Which makes reasoning about performance a rather hard thing to do.

>>Worse, it makes profiling harder than necessary. All the type coercions that happen at the API level will show up as separate functions, not attributed to the callee, but the caller.

I don't think it's that much of a problem she makes it out to be.

And it does certainly not mean the language is inherently slower, just that optimizing might be harder.

But hey, if you fucked up your C pointer arithmetic you will waste days finding a bug/memory leak you might never have had in C++, since you would use RAII there constantly.

Ease of optimization is bought with less robust code.

Depends on you what is more important for you. I'd take robust code every day.

I rather have a slightly harder time at optimizing than my program suffering under some hard-to-find bug I missed, because I have to keep working at a super low abstraction level.

>You shouldn't be surprised the lookup in a map is slower than in an array.

>But this is tied to the algorithms and also not inherent to the language, so I wouldn't call that hidden cost.

If I'm correct:

Big-O in complexity/time is amount of operations used, relative to n

Big-O in space is amount of memory used, relative to n

So right away, you don't know how many memory allocation calls it makes, when it makes them, how cache-friendly it is, etc. Considering the fact every object in the STL has a constructor/destructor this is a pretty significant lack of information. Unless you want to spend countless hours studying every single detail of every single class.

>2) If you have foreign code (from dependencies/libs/other people), well shit of course, I have to look at their code (or preferably documentation) to find out if its costly or not.

>This is the same for every language, so this is also not a hidden cost, that only C++ has.

By far the best feature in C++ is that it can use C libraries like OpenGL and header libraries like GLM. Because most C++ libraries are unreadable garbage. The most popular one that gets shilled all the time is fucking boost. FUCKING BOOST

<But hey, if you fucked up your C pointer arithmetic you will waste days finding a bug/memory leak you might never have had in C++, since you would use RAII there constantly.

>C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg. – Bjarne Stroustrup (the creator of C++

The ability to write code that wont leak is much more valuable than memorizing every structure in a language, because it can actually transfer to other language. What does memorizing the big-O of every container in C++ teach you, other than locking you into the language more.

Everything you said in Part 3 is the same rhetoric Java and high level developers use.

It does produce best quality qt faces but the dreadful performance makes it a gimmick. I can't even fathom how they managed to fuck up so badly. I was expecting its footprint to be marginal and it runs like babbies first script.

Also, the faces do not use any lighting so the scene needs to be always colorful and well-lit. Most postprocessing effects don't work either.

And Persona 5 seems to be using something like Unity's built-in lit toon shader with nicer outlines and the usual stylized textures, doesn't seem to fancy, unless I missed something.

and the opposite of that

>FXAA is the fastest option but blurs the image and does not fix specular aliasing, MSAA delivers a high quality image but does generally not work in a deferred pipeline. TAA is the new industry standard.

In many cases there are a shit ton of options with most of them just being inferior, and C++ is such a gigantic clusterfuck that an unopinionated guide would just be almost useless to someone who already knows the syntax.

>>This means you gain robuster code at no expense.

>But you still have to work around that containers implementation. If you know the context for the situation and can code accordingly. Containers and the compiler have no such luxury.

Not when it is a true zero-overhead abstraction.

std::array generates IDENTICAL assembly afaik.

https://godbolt.org/g/9MnTLs (not my code btw, haven't looked into it that hard, but you see the identical assembly.)

zero-overhead abstractions means the compiler sees you're using a std::array and optimized it into the same assembly a C array would have resulted in.

>I've been noticing a lot of performance C++ driven programs avoid half of what C++ has to offer.

Guess why they use the other half.

You don't have to use every single feature all the time.

Being a good programmer means you know when to apply what.

>Something I noticed is Mike Acton said he never used the STL, because it didn't solve any of the problems he had. They don't use dynamic memory allocation (like you would get form an STL container), they allocate it all at the start and have custom made memory allocators use the data. This is something you cannot do if you rely on the STL, but it also gives a glimpse into how these guys think.

I watched some of his talks, interesting stuff for sure.

Yet the main point is

>because it didn't solve any of the problems he had

I am sure most people here don't have the problem he has and will not benefit from thinking about L2 cache misses.

Of course, one could argue that skipping OOP and going straight to data driven design might be a better approach to learn game development.

I am not sure about that, but I can see the reasoning behind it.

>How does C++ improve maintenance costs? It's fine for projects where minimal performance is need but for games?

This might be just my experience up until now.

The stuff I have to code consists of both "this process takes 10 seconds anyway, since it talks to the hardware" and "this function has to run a trillion times on 250GB data, so make it FAST".

For the first stuff OOP principles for stuff like file handling, using RAII, creation of a data processing pipeline and similar stuff make for robust code, save a lot of time and are easily explainable to newly hired personell.

The latter stuff has to be very optimized, that's when you use data driven design, SIMD, trigonometric lookup tables, etc…

In the first part C++ features like using User-defined literals to convert units or make it impossible to add meters to seconds ( or stuff like auto length = 1_m + 1_cm //length = 1.01 m) saved a LOT of time for bug fixing for our department, just as an example.

And in this case it's free! Compile-time only (adds an extra second or so, not a problem in our case).

That's why I think "C only, never use OOP" is as wrong as "OOP for everything".

>>14608449

>Not when it is a true zero-overhead abstraction.

>std::array generates IDENTICAL assembly afaik.

You missed the point, but in std::vector the other container I mentioned, which is basically 1 step above std::array (which is a cherry picked example, considering it's literally a static array in a class that adds longer compile time). You ignored the issue I brought up that the iterators never have a consistent size unlike pointers.

vector<int>::iterator: 8
vector<bool>:iterator: 16

The original point though was the fact that thinking in containers like std::vector and std::array limits what you can do. Context matters What if I want to do what Mike Acton does, where he allocates all the memory on startup, then does dynamic memory by pulling from that memory space he allocated. Right away I cant use std::vector or std::array for dynamic memory, because they do not utilize the correct allocator.

>Guess why they use the other half.

>You don't have to use every single feature all the time.

>Being a good programmer means you know when to apply what.

They use the other half because 95% of it's C and 5% is C++. Even then I'm not sure what parts of C++ they use, because as >>14608198 said. In Acton's case he went for C++ to find dev's easier. I know Carmack used templates but regretted it later. This is why people say C++ is bloated out the ass. The language is full of landmines.

>I am sure most people here don't have the problem he has and will not benefit from thinking about L2 cache misses.

Are we not making games? This type of thinking leads to things like Dwarf Fortress, which is laggy as fuck despite having no graphical requirements.

>This might be just my experience up until now.

>The stuff I have to code consists of both "this process takes 10 seconds anyway, since it talks to the hardware" and "this function has to run a trillion times on 250GB data, so make it FAST".

>For the first stuff OOP principles for stuff like file handling, using RAII, creation of a data processing pipeline and similar stuff make for robust code, save a lot of time and are easily explainable to newly hired personell.

>The latter stuff has to be very optimized, that's when you use data driven design, SIMD, trigonometric lookup tables, etc…

>In the first part C++ features like using User-defined literals to convert units or make it impossible to add meters to seconds ( or stuff like auto length = 1_m + 1_cm //length = 1.01 m) saved a LOT of time for bug fixing for our department, just as an example.

>And in this case it's free! Compile-time only (adds an extra second or so, not a problem in our case).

Like I said, smart implementation can be done in both C and C++. Likewise bad implementation can be done to both C and C++. More tools does not immediately mean easier to maintain. C just requires you to be smarter with what you do, likewise C++ requires you to be smarter than Java.

>That's why I think "C only, never use OOP" is as wrong as "OOP for everything".

OOP is too heavily abused to be trusted and it warps your way of thinking.

From what I've heard, Alan Kay's original OOP definition was basically an awkward description of the actor model which everyone misinterpreted.

Big O only defines complexity. It's useful to look at an algorithm at a glance, and that's all.

Assuming a perfectly optimized code, it's possible to have O(log2) be slower or take more memory than O(n^2). It's just a measure of how many elements need to be compared.

My problem is that an engine feels too limiting, or handles things a certain way that I dislike, or tries to be a general case that ends up bloated adding base features I simply do not need.

I have written three separate vector math libraries in C++ at this point without any good reason, and they all do almost the same things. I think this is just a manifestation of autism.

It's kinda easy to jump to conclusions with that answer. You even said it's the industry standard, which implies more people in the industry are using it, which implies that it's easier to find people who know how to use it.

Fucking tier-1 advice. Avoid Boost. It's bad and is poor coding philosophy taken to the extreme.

>>14608605

More good advice. Let's list out the useful subsets for him though.

GOOD parts of C++:

classes are OK. Use them like C structs with functions and overloaded constructors.

vector, map, multimap, array, random are all decent parts of standard C++ lib and STL. But STL is generally BAD. There are better container implementations out there. EA's library is actually not too terrible.

Sony's SIMD math library is actually pretty good.

BAD C++:

Templates. Really. Unless you are writing a library avoid at all costs.

STL

Boost

Operator overloading

Class inheritance

Friend classes (or use very sparingly)

std::string. Just use the C functions, particularly the newer ones with character count protections.

streams, fstreams, iostreams, all that shit. dumbest shit ever.

delete and delete []. wait, this is actually the dumbest shit ever. Obviously you will have to use new and delete though. watch your ass.

Congrats on moving away from Java. I think you will generally find C++ pretty comfortable and useful. It's big draw is the many C++ libraries that are high-performance and well-written in general, especially for common game tasks.

>>14609014

Thanks for the advice, I'm the anon that said I was moving away from Java.

I had one quick question about header use. Should I always be using them to declare my methods? Or would some methods be better off having both the declaration and definition inside the implementation file? Do all of my implementations need a header file?

>adblock dies

>a million ads for the "infinity masturbator" show up

disgraceful

>>14608939

On that note, I'm using C# and looking over FNA (open source XNA)'s source code as a model. Here's what I have so far, but I think I need to redo a chunk of it for style and shit.

https://hastebin.com/vokotusoke.cs

Anyways, my concern is the redundancy for methods.

>public static Vector3 operator +(Vector3 value, Vector3 other) { }

>public static Vector3 Add(Vector3 value, Vector3 other) { }

>public static void Add(ref Vector3 value, ref Vector3 other, out Vector3 reuslt) { }

There's 3 different addition methods depending on how you approach it (eg, calling A+B, or doing a static method to add them, or doing said static method but by reference so you avoid copying the values and just basically use it as a pointer to the arguments). But then there's variants between V3 and float, that sort of shit. I feel like it's overkill but for vectors it seems like a good idea.

Also, what sort of shit did you put in your libraries?

>>14609156

>Also, a generic office keyboard and mouse will go a long way.

a generic mouse can be OK, but if anon has carpal tunnel or hand pain, I heavily warn him against using a keyboard with rubber dome switches. Low key travel and unpredictable actuation are a recipe for disaster on your hands. It makes your muscles and nerves do more work and have less muscle memory, and it means more physical impact for each keypress.

I don't understand how people use phones and touch screens, I think my hands are pretty good but it just hurts to type on them for more than a few sentences it's also infuriating

imo part of it is almost a deliberate design decision, like making cigarettes less efficient at delivering nicotine. the longer it takes you to type things, the more the phones train you to focus on the phones.

>>14609258

>>a dozen C# chimps start sperging out about how you're using the language wrong

all they're pointing out is that it's extremely inconvenient and basically impossible to keep stuff on stack in c# unless it's just a plain data struct. turns out muh everything is a reference is bad for perf. he should go back to a real language like c/c++ or rust.

>>14609067

Bunny hopping comes from the fact that the character accelerates as they turn. Aside from entirely removing that feature, there are a number of ways to prevent this.

Valve has a hard cap on the top speed, sets the player speed to the running cap when the player touches the ground, and makes it so that the player can't hold jump to repeatedly jump. Bunny hopping is still possible but it's much more difficult.

>I am shit at physics,

Git Gud.

You don't need more than Newtonian physics for something like this and that stuff is really easy, especially if you know calculus but even if you don't.

It helps if you think about speed in terms of an ADSR envelope, but without the decay. It takes some time to reach top speed, then that top speed is sustained, then it takes some time to stop. With a very short Attack and Release you get mega-man movement. Longer and you get Mario movement. Figure out which feel the best by creating a test level and experimenting.

>>14609429

A quirk in Valve's solutions means you can actually go much faster by jumping backwards than through regular bunny hopping.

C# is a perfectly valid language. You're right in that he should accept the paradigms of the language he's using. If he prefers to manage the stack/heap and memory himself, he should stick to C++.

>Everything is a reference is bad for perf

C# does not work that way. Value types (namely structs and most .NET-specified language primitives) are in fact, pass-by-value and behave as you'd expect. Prior to generics, if you had to use the "object" namespace and cast objects to different types (eg, a List which is a collection of object) and you wanted to add eg, a byte to it, then it would be boxed into a new reference instance and added to the collection. Nowadays with generics, you have a List<int> or what not that just does stuff automatically and avoids boxing/unboxing conversions.

The main issue is that the founding fathers were smart enough to recognize rich Brits trying to influence our country, but not smart enough to put any measures in place to stop Jewish rats from doing so.
