Reminder that C is deprecated.

(re-asking for help here)
Here's to hoping someone can help me, I'm probably about to look like an idiot though....
I've been working on this unity game for a while now, and my biggest hurdle is an attack script. I've been fucking with it for weeks and have tried multiple different scripts. Here's my latest attempt at attack:http://pastebin.com/UUdA8wQH
and here's the health:
http://pastebin.com/B8WQTXR5
The debug on the attack script does work in telling me my distance, and the health script was able to automatically remove health at a certain interval. I'm sure there's some really obvious small thing i'm missing, but I just can't seem to get them to work together so when i press Z the health bar loses help.
tl;dr: I need help getting my attack script to actually take health from the health bar / work with the health script.
Thanks in advance for any help.

"The most powerful programming language is Lisp. If you don't know Lisp (or its variant, Scheme), you don't know what it means for a programming language to be powerful and elegant. Once you learn Lisp, you will see what is lacking in most other languages." -Richard Stallman

I work in the GIS field and as such I code a lot in python a lot. Been coding in python since I left university. Recently I have been doing some coding of my own back at home and I think I should pick up some new language to learn.

What is another good language to learn? I have been exposed to C++ and C at University.

The degree one is stupid because it's phrased to ask what degree you HAVE, with the only other option being no degree. I, and I suspect many others on /g/, don't have a degree yet, but are working on one, so I think it's silly not to have an option for that. In any case, I'd say what field you're in (CS/EE/IT etc) is more useful information then whether you actually have a degree yet.

That's some serious undefined behavior you've got here.

You're confusing pointers and values, missing some &

>>58922731
>>58922758
More specifically, in Common Lisp it's easy to write macros that accidentally refer to a local binding, which can fuck everything up if the user rebinds mapcar or format or whatever. Hygienic macros perform some invisible name resolution using the context where the macro was defined.

>>58922797

>>58922804
Why did they design Common Lisp that way? Was it easier to implement or something? It sounds like a recipe for confusion.

>>58922804
And to top it off, CL macros typically make use of gensym under the hood, which generates a symbol to be used in the macro, to minimize the chance of capture. Redefining standard functions is undefined behavior of course.

When I use Greater than or equal to,it messes up the output of pi to 3.47.

        double i;
        double startValue = 3.00;
        for(i = startValue; i < (numOfLoops + startValue); i++) {
            if(i % 4 == 1)
                pi = pi + (4 / i);
            else
                pi = pi - (4 / i);
            if(pi == 3.14159) {
                endValue = i;
                break;

}

>>58923200
forget the endvalue thing too

>>58923200
You want to define an epsilon, for your function probably 0.000005, and then test

if (pi < (3.14159 + epsilon) && pi > (3.14159 - epsilon))

Practice practice practice the main business-friendly language they've taught you (e.g. Java, C#). You should know the basic language inside out. For example, if you're applying for a Java job and your main language is Java, you should be able to talk about covariance, its problems in mutable collections, wildcard generics, and PECS, among other things.

Be prepared to think on your feet to come up with an solution to a problem you haven't seen before. Don't rely on rote memorization of algorithms.

If you list a language/technology/framework/library on your resume be prepared to be asked about it. I may be in the minority here, but I'm unimpressed when an interviewee has put Haskell on their resume and then tells me "oh, I only did that in my first term at uni" when I ask them to write some code in it for me.

What year are you in at uni? If it's the first then they might cover it later on, but if you're near the end of your course and Java is your main language then I'd get reading. The online Oracle docs may be helpful.

Third year

To be honest, I haven't done much Java outside my first algorithms class. I'm focusing my degree on systems architecture and networking because I like low-level programming and infosec-related stuff, but it seems there's no money in those areas compared to Java work.

I'll grab that book, thanks for the tip

>>58923781
The full book is fairly pricey so if you can't get it from the library try looking for a used version.

If only one of your classes used Java, what else have they been teaching you?

>>58923796
As far as languages go, C, assembly, SQL, some python here and there, and lots of low level concepts and theory. Operating systems, compilers, processor design, high-performance computing

Used a little bit of java for one shitty project design class, but that's about it.

>>58923824
all the real money is in Java, web development, databases knowing php and sql, and IT security

>>58923824
Huh, I thought everywhere taught a significant amount of Java and/or C#. My earlier posts were made under the assumption that you'd done several courses in Java.

>>58923838
I know, but I don't want to be stuck doing Java and CRUD apps for my whole career.If I'm going to waste away at a cubicle for 8 hours a day for the rest of my life, I at least want the work to be interesting.

Surely some of these large tech companies hire people for writing device drivers and doing embedded programming, right?

>>58923841
I see

I would still like to learn about those things for my own knowledge, but I really, really want to avoid doing Java for the forseeable future.

>>58923894
Unluckily for you, Java and .NET are where a lot of the money is these days.

Need some advice for a noob....

I'm new to programming and I've been working with Java, reading "Head First Java". This is day 2 and I'm on chapter 6, and I'm already feeling discouraged/demotivated.

When I look up beginner coding projects, is it normal to just feel like I don't want to do any of them? Like "build a calculator" or "build a program that switches the first and last letter of a string", I look at those and I think to myself "fuck this"

I just looked at a bunch of example coding interview questions, just reading them made me sweat and feel nervous. I don't think I could ever pass a technical interview like that.

Where do I go from here? Is this a common thing for beginners or is it just that programming isn't for me?

Why do people use text protocols over the network?
It's not like it's a config or log file where user readability matters.

Binary protocols are:
- Faster and easier to parse
- Smaller, therefore performs better, and saves more data
- Simpler and cleaner code
- Less error prone

There is literally NO benefit to using a text protocol, AT ALL.

>>58925981

Which text protocols in particular are you objecting to?

>>58925998
All of them.

>>58926015

So you would object to, for instance, JSON as a data serialization format for web APIs?

>>58926026
Yes.

> Text as UTF-8 is the universally understood datatype, as opposed to all the shit you can get into if you use other things. (Big vs Little endian and what about representation? Is it sign-and-magnitude, ones' complement, two's complement, and excess-K?)

Yeah, if you have a fixed format that everyone knows, then this will all be fine. But if the content can vary, you're fucked.

Binary JSON is retarded. all non-retarded web servers compress the text before sending, so you're not even saving a lot of space.

>>58925286
Find something you want to do and do that.

>>58926080
>hur dur I'm retarded
Big endian is the standard on the web, so you obviously convert to big endian you retarded shit.
Two's complement would also be the standard or at least defacto-standard.

The problems you've listed literally do not exist.
Even if the representations aren't standard, they'll be standardized in the particular protocol you're using and developing for, you retarded faggot.

New to programming. About to start reading/working through K&R's "The C Programming Language (ANSI)". I use Windows; what IDE should I be using for C? Or perhaps I should be using a plain old text editor.

>>58922041
roll

>>58926032

Sounds silly then. JSON is a rather efficient format for serializing key:value stores, and because it is plaintext, it doesn't need to be converted to base64 when transferred over HTTP.

>>58926251
>it doesn't need to be converted to base64 when transferred over HTTP.
Uh. You don't need to convert to base64 when sending anything over HTTP..
You do realize that HTTP can send binary data right?
Besides, HTTP is a disgusting text protocol.

>>58925981
I dare you to program a distributed application without text-based protocols. You'll quickly understand why you need a text stream in most of cases: it's the universal message-passing interface across any possible programming language.

Binary protocols have their own use cases, namely buffer of characters. For anything that may include some sort of implementation-defined encoding, it's definitely not recommended and far more prone to error and difficult debugging.

>>58926377
>I could have sworn there was a problem with HTTP and binary data, due to certain byte sequences having semantic meaning in HTTP packets...
Well, I never had any problems transmitting binary data over HTTP when I made https://github.com/sora-chan/wakaba, and I used to host this for about half a year with regular users from different browsers, and no problems came up.
It had 682 files in the database.

>>58926536
>prone to error
Lol nope. At least no where NEAR as prone to error as parsing a text protocol is.
Parsing binary data is easy fucking peasy and not prone to error at all. Also because it's easy and not prone to error, debugging isn't a problem.

>it's the universal message-passing interface across any possible programming language.
If your programming language can't read binary data either directly (raw) or common standard formats, then it's a meme and no one serious gives a fuck about it.

I work in research and development, making next generation software/hardware. C is the only sane option for embedded systems because it's the only (commonly used) high level language that doesn't hide the low level functionality too much.

>>58927795

Torvalds is a blithering idiot.

C is in fact obsolete, and calling everyone who points that out "incompetent" is not an argument. First, because it's not a refutation of the points they make, it's just a red herring. Second, because they usually aren't incompetent, they're security experts who exploit C for a living. They can write C. If anybody can, it's them as a matter of fact.

We know how C is poorly designed. The standard library is erratic in its string treatment, pointers are dumb and memory management is simply a clusterfuck. It's a great language if you love buffer overflows, but it doesn't really provide any added benefit. It's not a sane option, there are better designed languages that don't hide any low-level functionality from you - whether it's new languages like Rust or even old ones like Pascal.

Keep telling yourself your language is immaculate, kid.

Get a room, guys.

I agree with you, but you sound really dumb and edgy. Work on your persuasive writing skills or stop having the same opinions as me.

>>58928005
What's stopping you from reference counting your shit?
In fact, a lot of things use reference counting.

>>58928022
You're making a bunch of general statements about a large group of people, with absolutely no evidence.
Seriously, you're pretty much just saying "I'm such a l33t hax0r, because I broke some code a novice wrote".
I don't even know which language you're arguing for to replace it.
If you say C++, you're fucking retarded.
If you say Go, you're fucking retarded.
If you say Rust, the jury is still out on that one. However, Rust and its ecosystem has a lot of its own problems.

I don't care what you think.

>Work on your persuasive writing skills
I'm not here to persuade people. I don't feel the urge to convince everyone I'm right, I'm not a teenager anymore. Let them believe whatever they want, I don't give a fuck.

>I don't care what you think.
Yes you do. That's why you're posting on an image board, you dumbass.
>I'm not here to persuade people.
Shut the fuck up, then.

Lmfao the Hard Mode / Fuck you mode for the Chip - 8 Emulator suggestion I made is still around on that image?

Legitimately I don't even have the code anymore from when I made that suggestion.

Will the language wars ever end here?

Not until all of the Sepplesfags fuck off.

When WW3 happens, only C and Lisp will remain.

I feel no need to keep code around for a bunch of small one off projects that I don't intending on publishing or maintaining.
