Hey guys how do I start learning how to program.
I'm an 18-year-old girl btw.

>>52472577
you'd need an exact image of 2011 this is just some VC blinded old man went back to school and finish your studies drops instantly as soon as Pascal comes out when everyone is buying pascalI mean, there can't be bothered to rewrite it in tandem with social engineering.

Turns out my shift right and shift left opcodes were totally wrong this whole time. I was shifting the values by 4-bit hex values at a time, instead of 1-bit binary values. All fixed and good now, but I've been blowing off gameplay since it's a much larger beast

Other anon is writing Pong, in a chip 8 emulator he has written. Chip 8 is basically a very small assembly like language, that you can run inside a VM/interpreter. It's not an actual hardware system, just software.

>>52473090
It's my version of CHIP-8 assembly language which is converted to binary code for use with the CHIP-8 emulator I wrote.

Tools:
C - emulator
CPython + IDLE- assembler, code line to memory address converter, sprite to hex converter
Notepad++ - for editing C and my .c8 files
command-line - running/compiling c/python code
Notepad - notes

>>52473135
Neat. I'll probably just stick with learning to make Pong in C++, but I am impressed.

Why? Is it blocked by feminine code that won't let you through until you pay attention to her?

Inheritance does not work for static methods. You can't call the parent static method.

Reminder that we're all girls and anyone who says otherwise is ironically shitposting

>>52473609
I did. It was the lua game beginnings.

If there's an actual woman here, I just wanna ask:
How does it feel to be 2nd? No offense, but it's scientifically proven that men are physically and mentally superior to women.
I just don't know how it must feel to you girls knowing that you will NEVER be the best at anything.
I mean, that must be pretty depressing, right? Knowing that you'll never be able to compete with us men with literally anything.
I just feel sorry for you women, that's all. I just wanna know how all of you can go through with your lives normally knowing the fact that you're inferior to us in almost everything.
If I were you I would've just killed myself and hope reincarnation is real so I can reincarnate into a man.
Just thinking about how you women must feel makes me sad.

>>52473632
Boost is great if you want to write feminine code.

>>52473583
Well I'm trying and it isn't.

>>52473587
It's just not working, I don't know why.

>>52473588
???

Where I instantiate the class.

InputParser inputparse = new InputParser();

that class has this method

        public void ircWriteLine(List<string> output)
        {
            foreach(string line in output)
            {
                MainWindow._irc.SendRawMessage(line);
            }
        }

And this is what I'm trying to call.

public static IrcClient _irc;

public static doesn't throw a compiler error, it just doesn't work. public on it's own throws an error.

You're declaring _irc as an instance of the IrcClient class and with public access. This isn't, if you thought, declaring _irc as an instance of the public class IrcClient.
In other words, adding `public` to _irc won't actually change how it works compared to just

IrcClient _irc;

.

I can't seem to find the definition of IrcClient but that's probably where you're problem is.

>>52473923
Carmack teaches his kid Racket.

>>52474053
Then the error becomes "MainWindow._irc is inaccessible due to its protection level"

That's why I initially went with public static, because only public static stopped throwing compiler errors.

Unfortunately it didn't actually work so I was back to square -1 anyways.

>tfw this is the result of being too lazy to only clear changing parts
Should just be a matter of not calling my draw subroutine every time only the loading circle changes, and every time it does change draw the same loading frame on top (so it cancels it out), then draw the new frame after

progress is being made at least

Long story short I got in over my head on a hobby project.

I now want to dynamically generate names based on a set of linguistic rules.

However, that sentence contained 100% of the information I possess as to how to create those things. Does anyone know of any resources or similar applications or anything else I could consult? I'm about to go to the library and see if there's not some dusty old tome written by a Linguistics PHD somewhere that might help me out.

can someone explain interfaces in java in two sentences ?

I have some trouble understanding them

>>52475192
A means of guaranteeing some type implementing them has methods of those type signatures.

>>52475192
they're like fake classes that other classes can build off of, for sharing behavior and expectations of behavior across multiple classes

>>52475192
It's easy to understand if you've ever made an iterator in python, if a class has an iter and a next function, you can pass it into any function that takes in iterators. In Java, by saying a class has an interface, you're saying you can pass that class into a function that needs an object with certain functionality, because to use an interface you must write code for all the functions it wants you to use

>>52475070
This is fucking ridiculous. I have a float that starts at 128.0. First I subtract (128.0/10.0) from it, and it becomes 115.2. Then I do the exact same thing again, and it becomes 102.2. It's supposed to be 102.4, what the fuck?!

Depends how accurate you want to go.

Chip8? My negro. I wrote an emulator in Scheme about a year ago, with ncurses graphics. No mutable state for funsies. No where near as complete as yours though (no assembler or any other tools, just used a hex editor for everything).

I highly recommend it to anyone wanting to get into the emulation scene, the instruction set is super simple and there are lots of freely available demo programs.

>>52476202
The difference is that interfaces are compiler-safe and closer to a modular black box. You don't need to look in and see what functions other functions need, your compiler will tell you.

>>52476241
Yeah CHIP-8. I agree it's quite simple even if daunting at first. My assembler could still do with some work (no labels means I have to recalculate where to jump to every time I add or remove a line of code), and maybe an extra higher-level language on top that's exactly like the opcodes/assembly language but slightly closer to english

retarded c# question here

In my game, I have a score counter label and a score counter. When the score increases, rather than instantly setting the score counter to the new score it's lerped to it. However my game is now almost done and I'm in the micro-optimization stage so I was concerned about how much garbage this might be generating. Here's a slimmed down version of what the code looks like:

void Tick() {
if (current >= target) return;
current = Lerp(current, target, time);
SetScoreCounter(current.ToString("0"));
}

How can I optimize this? If this was for PC I wouldn't bother but it's for mobile so every little thing counts.

Have you thought about just implementing an actual high-level language? Not too high level, just like C or something. Writing toy languages is a bit of a hobby of mine, and there are a ton of tools to do it in C. Pretty much just comes down to writing a simple parser with Lex/Yacc (or probably Flex and Bison nowadays), generating a tree, and then walking that tree and spitting out code for your assembler of choice.

I can just implement an interface to have a rough structure of that class ? neat.

so the interface is a diet-abstract class, it doesnt do anything itself, it just tells other classes what they could do ?

two classes could implement the same interface but do something completely different with the given methods ?

>it just tells other classes what they could do
It tells other classes what they SHOULD do. Think functional for a second. You want an object to be the basis of an algorithm, but for it to work with the algorithm, it needs to have some basic functionality. For example, I have a pathfinding class. I don't care what heuristic class I use as long as that heuristic deals with reading info from a grid and produce values for each grid space

>two classes could implement the same interface but do something completely different with the given methods ?
Exactly. 2 different heuristic classes will produce different values for each grid space. 2 different classes using a Window as an interface will display your output differently, but they all need a closeButton function, for example, and maybe one class will prompt you before exiting, while another won't

First project was a compiled language that was pretty much just C with first-class functions (and anonymous functions alongside them). Finished, got bored of it pretty quick.

Did a VM for a made up architecture (a shitty one because I know nothing about design) next, along with a compiler to that VM (pretty tightly bound, sort of like how most modern scripting languages work). I had been writing some shitty games, and I wanted a scripting language that wasn't "opinionated" like Lua, for example. Tried to make something super easy to embed. Implemented quite a bit of stuff: closures, callbacks from C, garbage collection, loading a shared object file as a module, etc. Got a pretty decent Github following for a while (~300 stars), still tinker every once in a while.

Now I'm writing a concatenative language to explore some ideas about a macro system I was thinking about.
