The anime. Why the hell would I read some fag mango?
I'm writing an NES emulator for fun. I need to pick a graphics library though.
I might use Vulkan since it's new and I'm pretty sure there isn't a Vulkan NES emulator yet.
Any suggestions?

Obviously, considering the Vulkan standard hasn't even been released yet.
>>52028647
Because the anime is only 4 minutes per episode, and frankly it's just a cheap and shitty experience compared to the manga which runs for much longer and actually has some depth and character development that couldn't be had in 4 minutes of animation.
>>52028663
Oh it hasn't? That's a shame. I just got to the point where I need to pick a library and I vaguely remember /dpt/ talking highly about it.
I suppose I'll just use opengl then.

go through the output line by line and reverse engineer it. what do you need to do on a line-by-line basis to create that output?
>>52028801
It's really not that difficult.
Just take the length of the word and add that many spaces between every letter and subtract one for every line until that distance becomes zero.
For the middle, just print out the string and then the string in reverse minus the final character.
For the bottom, just do the top part, in reverse.

It's slightly easier to use than MonoDevelop and it has less annoying shit out-of-the-box (apart from the ridiculous bloat and the forced registration)
I personally switched to MonoDevelop over a month ago but already had to write 2 AddIns to make it useable
Daily reminder, in the industry no one cares if you can write a function in one line. The only thing that matters is 1) if it works and 2) its readability for future maintenance.
If you don't make your code readable, then you aren't getting the job. Period.

The latter is more readable than the former, so no.
The only reason I bring this up is because I work on large scale code bases all the time and it really bugs me when a developer thinks they're being cute and makes something more complex than it needs to be with no documentation.

I've got the json.net lib, but I have no idea how to use it.
I want to generate local config files with defaults and then create a copy of that as usersettings.
I'm not sure how I'm meant to generate the defaults and plug it all in.
I'm so tempted to use the default settings object in .NET but it's a load of old shit when it comes to how it does settings, and I wouldn't be able to save my ObsCollection of a data object into it.

Does anyone know anything about Json.net?
I'm trying to serialize/deserialize an ObservableCollection<DataObject>, but I have literally no fuckin' idea how to do it.JsonSerializer serializer = new JsonSerializer();
serializer.NullValueHandling = NullValueHandling.Ignore;
using(StreamWriter sw = new StreamWriter(@"c:\json.txt"))
using(JsonWriter writer = new JsonTextWriter(sw))
{
serializer.Serialize(writer, SongList, ObservableCollection<Song>);
}SongList = JsonConvert.DeserializeObject<Song>(@"C:\json.txt");
this is what I've currently got, but apparently I can't serialize to an observablecollection<song> because it's a type (which is fucking dumb because it's what it fucking asks for).
Does anyone have any idea at all? I can't seem to find anyone with the same issue.

string file
for i in file.length

Anon who had the problem understanding classes here. Created a class for a little test of my knowledge. Am I doing well?
http://pastebin.com/XJmZG0sT
Also still didn't understand the concept of inherited classes. Like let's say I want to make a class "Player" that can use functions in my Sprite class or modified classes from that class, but also new classes and variables. How to I proceed?
>>52030855
Also, don't forget to empty out your line variable so you don't accidentally stack your lines.
>>52028898
Maybe one day people will listen.
Maybe one day they'll even understand.
>>52030864
Your sprite class shouldn't be a class of its own, but rather be an interface. The Player is not just a Sprite, but has many more components. HumanPlayer and AIPlayer should derive from player because they are players.

Sprite itself does nothing. It merely describes what the class which implemented the interface can do.

How'd I go about opening one up, dumping a bunch of data to it and binding it to the interface?
If I can't bind the data to the interface (at least in a read-only fashion) then it's pretty useless to me.
>>52031003
I still stand by my point. You shouldn't be using inheritance when you could have a PlayerEntity which contains a "SpriteComponent"

My thought process is that I made a sprite class containing the minimum of actions every sprite can have, whatever type they are. Of course I will made other classes depending on this one.
I'm still not at ease with interfaces, how should I approach this?
>>52030864
Determine which class has functions that are exclusive to it.
A 'Player' can't necessarily fly, a 'Sprite' can. So, depending on the context you could decide to allow the Player class to fly and span out from 'Sprite' ( meaning you would make a Player class that could fit every character ) or you could make a Player class and extend it's functionality to that of the Sprite class.Monk Sprite

>>52030954
Not him, but I'm making my own game, and my thought on the matter is that since the player isn't actually beyond the game and instead act on the meta-particulars of the game they are actually working in the background. That includes the AIPlayer. If my thinking is correct, not that it should be, then the Sprite would be the highest level and it would "think" to do something, that "thought" would get sent back to the background processes and it would get processed. Once processing is complete, the signal to move, attack, talk, etc. would get sent up to the Sprite so that it then acts.
I think maybe putting the interface above the Sprite would make for a few extra layers of complexity (lag ) between the player and the processor. For an RPG, I think either is fine but for the most part, I think, since the player is balancing the knowledge of the process and what's on screen, the player interface should exist between processor and screen rather than have it go processor -> screen -> player.
Just my thinking on it, especially if he's thinking of going 3d.
>>52031100
I want to modify the HTML clientside, not serverside.
Here's an example:
When I run this program, and go to 4chan, it would modify the HTML code which my browser loads, and add a huge text which says "You're a faggot." on top of each page. This is just an example.

Don't listen to nay sayers. They're either clinging onto ancient wizardry like C or use shit like Haskell.
What should I do to move on from programming basics? I've messed around with various languages over the years but the only things I've done is really simple stuff. I've went into games a little but nothing serious (just mario clones/tile editors in python and some messing around with Java2d).

Yup, but I parse the information I want out and dump it into an object.
I just need a way to store the object locally and be able to bind it directly to the interface and write to it.
>>52031223
So either keep the object around in memory (and regenerate it if your application is closed/killed) or dump it to disk.
Personally I'd dump it to a SQLlite/SQL compact databse, but if you don't know the first thing about databases and Entity Framework, dump it out to a file.
>>52031132
You're right, the interface isn't really needed if everything's derived from Sprite.
I don't really follow you. What's a processor and what do you mean by background processes?
>>52031232
I'm just worried about the time it'd take to load the data from a file back into the object, I'm sure I'll figure something out though, just use JSON and dump the thing I guess.
>>52031252
Why the fuck do you care? You aren't doing this loading every frame, right? If your application takes an extra 100ms to startup no one will care (and it won't take that long).
>>52031223
If you want to save such a small object, you might as well just make use of Object Serialization. This way you can just load in a object from storage when starting up your application and write to it. When done, write the object back into storage. This way you don't have to fuck around with any databases, xml or json shit.
I think there is also a flaw in your thinking. You don't bind your GUI to things that are saved in your storage, only to things directly loaded into the memory of the application.
>>52031139
You could register a service worker, assuming you run a modern browser (chrome).

My point is actually that he shouldn't derive everything from sprite. That it should be derived from object/task then to player and then to sprite. This way he can implement sprite using the player abstract functions and not have to create quirks in the system that only apply to one or two particular characters, which can and will throttle the system if the characters aren't balanced. This only if the intent is to create a balanced and well performing game.
It should look like this:
virtual object -> abstract player -> character sprite
I mean that since it's a game, the presentation matters. And that since it's a game, the learning process is inherent and should eventually become "second nature". If you are constantly forcing the player to focus on some kind of external stimuli then they never really learn the game as it was designed and will probably become annoyed, bored and quit playing the game.
The processor is the engine. The game runs map, foreground, hud and the player interfaces with the game at the map level. He moves on the map, his position is made apparent in the foreground and actions/consequences are clarified in the hud. In throttling the engine by making calls start at the sprite level you are black boxing terminal locations and creating latency.
Kind of like playing on a HD tv versus playing on a CRT. The info is sent to the TV and then the TV still has to stretch the image ( process ) which creates lag between user input and what is shown on screen.

But seriously, there are times when one liners are great.
Usually they're times when you wish what you wanted to do could be done on one line, but normal syntax doesn't work until you find a nice workaround.

Producing hardly or completely unreadable code is bad habits.

Well if you want to get a job out of it, yes.
Or if you want to contribute to open source software then still yes.
If it's just your own code that nobody else is going to see then great, do what you like, just don't expect anyone to give a shit about it.

Most sane people have come to the same conclusion, I'd say.
I'm trying out ocaml now because if it really gains parallelism as planned, I think it will end up being the sanest language around, even if it's still shit (case restriction based on object, non-uniform arithmetic syntax, overflows and underflows, no arbitrary unicode in names, no at least -*/ in names, etc.).
The only other option is to start writing your own language.
