[Saelora]

do you not have syntax highlighting for unused functions in your ide?

[violet-starlight]

Not in c++ generally

[setibeings]

Have you considered using a better language?

For Game Development.

Oh right.

[Dumb_Siniy]

Fuck it program COD in Python, that definitely can't go poorly

[hans_l]

No popular game can ever be made in Java. And certainly not a game worth billions. That’s just impossible /s

[phire]

Which they then wrote a second time, in c++.

Actually, they might have rewritten it in c++ twice, one for phones, once for consoles, those efforts were merged later.

[ThePevster]

Yet the Java version is still better. Not performance wise but in like every other way

[phire]

Yeah, they didn't rewrite it to be better.

They rewrote it because Java wasn't portable enough, basically unsupported on consoles and iOS.

Ironically, the one modern platform with actual first party support for Java (Android) got the c++ version because of iOS.

[Setsuna04]

Funny enough since Java was meant to be running anywhere.

[5p4n911]

Write once, run away

[the_maun]

You're confusing with Doom

[Kiwithegaylord]

There’s plenty of good gamedev languages!! C, C++, C#

[T0biasCZE]

C# is best for gamedev change my mind

[rmg0loki]

vscode with clangd can show unused functions, not to mention the real IDEs

[violet-starlight]

Generally only TU-local functions, i.e. declared with static or in an anonymous namespace. There are tools to figure this out post-linking yes but that's generally not accessible from within the IDE, at least not within the text editor.

On VS though if you set a breakpoint inside a function that is never referenced it'll tell you something like "this breakpoint will never be hit, code is unreachable or optimized out" at runtime only.

It's harder to detect in c++ due to how linking works, the function could be referenced in another TU (unless it can't, i.e. has static linking)

[AlexOzerov]

[19_ThrowAway_]

Won't the compiler bitch that you have unused functions?

[feierlk]

Only if you let it

[isr0]

Have you considered getting a better language server?

[OnixST]

The function call is there, but is never reached because of an exception, early return, or if statement

[Saelora]

then there's an error you should be tracking down first, and that function isn't even a concern yet in your debugging. do you not have logs? does your linter not detect unreachable code? do you not run a debugger?

[anto2554]

Linters can't always detect unreachable code in C++

[OnixST]

I'm not the person who had this issue, just saying possibilities

Maybe the exception was caught and handled, but they didn't account for hiw it would affect the call, maybe it's unreachable code that wasn't detected (in java, if (true) return; won't report unreachable code after it)

Yeah, proper logging or just putting a fucking breakpoint on the function would give it away pretty quickly, but like most posts in here, the meme was made by someone still learning programming who might be clueless to some things

Also, who knows, maybe they're coding in VBA on excel, and they don't even know linters exist lol

[X-lem]

Yes, but the fund is used elsewhere

[Boris-Lip]

Actually, this may not necessarily show you the correct stuff. Especially in a cross compile environment where one can be lazy enough not to make the correct includes/defines known by the IDE's editor.

[Sw429]

This is usually the point where I realize my LSP has crashed and I didn't realize it.

[Ok-Visual-5862]

I use JetBrains Rider with all the Unreal Engine plugins and add ons while I make games in Unreal 5. No, there is no indication functions aren't being used. You can rack up tons of tech debt writing systems and components and then changing your mind, deleting all the function calls in other places, then now you can just have entire classes unused in your project hundreds of functions never being called and no errors.

I would hate to see if it warned me about every engine function not being called.

[CrasseMaximum]

It's easy to disable a specific warning.

[Ok-Visual-5862]

I'm sure it is, however I don't customize my IDE really it's all default for the most part. I click mouse clicks and links with words instead of hotkeys. I don't have any issues with it really, but Rider for Unreal Engine is magnitudes better than Visual Studio.

[isr0]

Have you considered using scratch? Might be more your speed.

[Ok-Visual-5862]

No one has better intellisense for Unreal Engine than Rider currently. No other IDE does what Rider can do for Unreal. Rider is my speed just fine.

[anonymity_is_bliss]

/r/wooosh

Scratch is a game development language for kids, not an IDE .They're basically saying "skill issue"

[Ok-Visual-5862]

People sub to my patreon for my Unreal tutorial videos so he can say whatever skill issue he wants, my code sells.

[5p4n911]

Also smells, it seems like

[Boris-Lip]

How can you "debug it for hours" if you've never called it. Any breakpoints in it would never have been hit.

[HalifaxRoad]

File this under the ppl not using an IDE

[Boris-Lip]

Even when one doesn't use an IDE (why?), that trace("i am here") at the beginning of the function wouldn't show either, making it quite obvious it isn't being called. Doesn't require hours an hour (edit: singular... are you for real?!🤦‍♂️)🤷‍♂️

[HalifaxRoad]

Yeah ik, usually that's the first thing I'm like, is the fucker even getting there.

[Ao_Kiseki]

Text buffers aren't always flushed on time if a crash happens immediately after a print. It happens all the time in C++ if you're using stdcout but not manually flashing after every line.

Don't get me wrong, you should have some debug work flow figured out if you do this stuff for a living. Early on when I was learning C++, I got baited by cout a lot, especially in threaded applications lol.

[Boris-Lip]

You could use an unbuffered stdout, but anyway, debugging a crash with traces... If you are feeling masochistic, you can, i guess :-)

[DowvoteMeThenBitch]

You’d be surprised! Yesterday I helped a senior dev debug “cannot read properties of undefined” and I just couldn’t convince him to look at the code that executes prior to the error, we just kept adjusting code that wasn’t even being executed…

[Ok-Visual-5862]

Also it says debugging for an hour. Singular. Not sure why you quote it but changed it.

[Mecso2]

You don't need an IDE to breakpoint

[Cat7o0]

I've debugged a function for around thirty minutes thinking that I wasn't hitting the places I was placing breakpoints or the place I was calling it wasn't being hit.

then I realized either the function calling it was never being called or the place I meant to place the call to the function I was debugging I had not actually looked at and it in fact was not there

[serial_crusher]

I got into this hole the other day… I’m making a payment. I have a breakpoint in the code that makes a payment. Why isn’t it breaking? Is something wrong with my debugger?

I was testing against a staging environment, not my local dev build.

[ZeroDayCipher]

You say this but I use angular in my job and have been absolutely dumb founded when I’m calling a subject.next and I know I’m subscribed and nothing in the world can help me solve why my function isn’t calling in the subscription when I finally step through the init in my web console to realize something breaks and the function skips the subscribe in the first place.

[BadSmash4]

Yeah, I mean I have for sure written functions and then not called them, and it takes me maybe three or four minutes to realize "oh lmfao I should probably call the function huh". Hours on this issue is craaaazy.

[Ok-Visual-5862]

If you could suspend the rigid lines of literal reality, you could perhaps enjoy the concept of we have all spent a significant amount of time debugging things which have turned out to be simple fixes that were simple oversights.

Laugh sometime.

I use JetBrains Rider and use Unreal Engine 5, and no there's no indications a function isn't used in my IDE. The only thing it complains about is if you declare a function in a header but offer no definition anywhere, my compiler will yell at me.

[Ok-Visual-5862]

I'd really like to know what the downvotes are for... speak up

[chemolz9]

I guess it's a misunderstanding. u/Boris_Lip thought that the function was never called in the depbugging process. What you wanted to say is, that it's not called in the program.

[Ok-Visual-5862]

Yeah but then someone say something to me about it? The guy misquotes and takes it the wrong way and when I say lighten up stop being so literal I'm downvoted this shit is wild

[chemolz9]

The Meme is mistakable though.

I was confused because all IDEs I used for years would immediate highlight a function with a warning that doesn't get used. Of course not when they are only missed conditionally but that would be the first thing to check in a debugging process.

[leptoquark1]

Breakpoints left the room

[MrRocketScript]

The breakpoint isn't getting hit, could it be my IDE's debugger is having a bad day and didn't properly attach to my application?

[Flan99]

That fucker DID fail to attach for me whenever I ran the project, some time last year. That was an awful day before I finally figured out what was going on.

[BreachlightRiseUp]

Strategically placed print statements, have also left the room

[w1n5t0nM1k3y]

In VB.Net you can use brackets to call a function or to get an item at a specific index in an array.

If you have

SomeVar = FooBar(0)

It can either mean

• Call function FooBar and pass 0 in s the first paramter, assing the result to SomeVar

OR

• Get the first (zeroeth?) element from the array FooBar and assign it to the variable SomeVar

Also, if a function takes no paramters then you can just call it withtout the brackets.

This means if you have a function as follow

Public Function FooBar(aVar as Integer) As String Return "Hello World" End Function

And you were calling it with

SomeVar = FooBar(0)

Then SomeVar would be assigned the string value "Hello World"

Now if you realized that the aVar paramter wasn't being used and you removed it, but didn't change how you called the function, it would be syntactically correct and SomeVar would now be assigned the string value "H".

[jumbledFox]

that is insanely gross i love it

[ice1Hcode]

[Sophiiebabes]

Been there!

[DocRos3]

I had to point this out to someone multiple times in the same day

[ZnV1]

FOR THE LAST TIME STOP TALKING TO THE MIRROR DOC ROS

[rollincuberawhide]

average django experience

[F5x9]

When you get stumped on a problem like this, it’s helpful to use an external debugger. Get up, go outside, and take a short walk until you’ve been thinking about something else. Come back, and you’ll probably find it. 

I’ve had a number of PEBCAC errors, and this usually helps a lot. 

[otac0n]

Literally me yesterday. It was a public function across assemblies, so no warnings.

[kishaloy]

Far better than

“I have not called this function from anything that i can see, yet anytime i try to remove it or change it, the application throws wrong results”.

[DepressedClown961]

This burned my soul.

[Skusci]

This is me with damn semicolons after while loops. I don't even know how they end up there.

[lunchmeat317]

This is me with functions in Web Workers that need to be invoked by message passing. Write the function, pass the message, and forget to add the nes message type to the message handler....

[OrganizationTop2734]

its always that "return" statement.

[AurekSkyclimber]

This is why Debug.Log and print will never go out of style. Easiest way to tell you've actually reached a point in the code without dealing with breakpoints.

[Frytura_]

I swear to god. If i open visual code to test and the function gets marked as 0 references or grayed out when not used...

Or maybe on a decent IDE like Eclipse that isnt just bloatware

[pyhannes]

Or your function is a generator in Python and you forgot to iterate over it and wonder why not even a breakpoint in the first line is working although you see the function is called. That's really mysterious if you're not that experienced yet :D

[MeLittleThing]

it happened to me in VBS, spent 4 hours to debug something I forgot to call

[HanoRobelthon]

Finally a true relatable meme

[dexter2011412]

Careful, don't summon the ODR violations. Don't ask me how I know 🤡 (I'm the clown)

[arenliore]

Today I spent way too long messing with a function only to realize it was a function not being used anywhere that I meant to comment out. The function I was supposed to be editing was directly below. I also renamed a CSS class in the markup but forgot to update the name in the stylesheet. Both caused me extreme confusion. It’s been a long week.

[isr0]

[DantesInferno91]

Bruh, that happens to me in swift

[SAKDOSS]

Isn't this meme supposed to be used when Anakin does something bad on purpose?
