Q: Call a method without calling it

Inspired by a now deleted StackOverflow question. Can you come up with a way to get a particular method executed, without explicitly calling it? The more indirect it is, the better. Here's what I mean, exactly (C just for exemplification, all languages accepted): //Call this. void the_function(v...

someone might have an idea

@AlexM. lol wut

Alex M.

that's my new meme

next time when Pip comes to tell us about Kivy

I'll say "Are Kivy really powerful? If so I want some."

hasherr

Is that what he's been doing lately?

Please tell me I didn't know.

A: Call a method without calling it

import sys def the_function(*void): print 'Hi there!' sys.setprofile(the_function) This sets the_function as the profiling function, causing it to be executed on each function call and return. >>> sys.setprofile(the_function) Hi there! >>> print 'Hello there!' Hi there! Hi there! Hi ther...

a non-C answer!

@AlexM. Is that your SO account in that picture?

Alex M.

no, it's

hasherr

Okay, I was going to say.

BlueBug

o_o 145k that's like a dragonborn, yeah, with his Fus Ro Dah! he can blow the entire server.

hasherr

That's an awful lot of rep for a game dev who mainly lives on GD.SE

@BlueBug He is literally Dovahkiin

Is there anybody on SE that has achieved more than 1Mil?

A: Why is processing a sorted array faster than an unsorted array?

You are the victim of branch prediction fail. What is Branch Prediction? Consider a railroad junction: Image by Mecanismo, from Wikimedia Commons: http://commons.wikimedia.org/wiki/File:Entroncamento_do_Transpraia.JPG Now for the sake of argument, suppose this is back in the 1800s - before...

BlueBug

Fus Ro Cha!

hasherr

Holy literal fuck. That is the longest answer to a question that I have ever seen

@AlexM. TIL that Mystical is the inventor of the circle, lol

Alex M.

that python thing in the answer sure is interesting

I thought of so many shortcuts I could take

using that thingie

hasherr

2:00 AM

So far I'm having fun with HTML.

It's pretty easy.

Alex M.

of course it is

hasherr

lol, it's just markup

Alex M.

it's one of those things that any developer, ever, can do

but it takes an expert to get a great result

hasherr

I also bought this book

amazon.com/gp/product/0735611319/…

Have you read it, Alex?

Alex M.

nope

hasherr

2:03 AM

It's interesting.

Alex M.

might take a look at it later

hasherr

It's basically just a book about how computers work, which means you probably know most of the things in it.

But I really like it. It talks about other things too, like different kinds of codes and history.

Christ, you should go for it.

Alex M.

shrug not sure I can do something like that

William 'MindWorX' Mariager

I thought OpenGL was open source.

Alex M.

besides, I dunno what to do with $10k

hasherr

Buy more games and chocolate

Alex M.

I mean after I'll get my new phone and GPU

hasherr

2:34 AM

And then give it to me.

LeSam

2:47 AM

hi

is there somebody using libgdx ?

hasherr

I use it :P

LeSam

hi hasherr

hasherr

@LeSam How'd you change your identicon?

LeSam

I have no idea

it changes everydays

hasherr

Waayyy I want a new identicon

LeSam

2:51 AM

well Do you know if it's possible (on android) to execute a HttpClient request async in libgdx ?

in libgdx not in the android activity

hasherr

I need a little bit more context than that

What exactly are you trying to do?

LeSam

I'm trying to get a JSON information on the web, and use it in my libgdx game

I must take this a way async

hasherr

Hmm... I don't see why not.

LeSam

I just want to know if it's possible to do it directly inside libgdx class

hasherr

I'm not sure. However you do it, you just need to be careful about it so that you don't violate Android standards.

But I don't really see why not.

LeSam

2:56 AM

ok, I've made it outside libgdx (on android activity, and I don't know how to send the information to libgdx)

hasherr

I need an idea for an App for a competition.

LeSam

I have no idea

btw, do you know how to send information from android activity to libgdx ?

hasherr

What kind of information are we talking about?

LeSam

any information, a Integer if you want

hasherr

Well, my guess would be to make a constructor in you ApplicationListener class and then send the information there initially when you start your activity

LeSam

3:00 AM

yes but I would like to send informations after that libgdx class has been launched

is it possible ?

hasherr

Well, first of all, why are you messing with your Activities?

I don't even touch mine in my game.

LeSam

sometimes you need to do somethings that libgdx can't do itself

like take a picture, write a message

do you see what I mean ?

hasherr

Yeah.

LeSam

In my case it's write a message

hasherr

I don't know. Try googling it, or trying to do it in your own way without paying attention to how other people do it.

Did I tell you what I did for my UI?

LeSam

3:05 AM

this is the concept, the PLAYER write his name, and the name is sent to the libgdx class

no you didn't

hasherr

I found LibGDX's documentation for their skin-based UI to be useless.

So I literally wrote my own UI classes

LeSam

me too

I did that too

hasherr

You agree with me?!?!

LeSam

I recreated buttons, checkboxes etc.

hasherr

That's what I did too.

LeSam

3:07 AM

Yes I agree

because it's not enought documented for me ! not enought exemples

with images !

only exemples with codes

hasherr

They're pretty simple, it's just a class called Button which extends Sprite and then when you instantiate it you give it a LibGDX Action which acts kind of like an ActionListener from vanilla Java.

@LeSam That's pretty much flawed documentation.

I would argue that examples are part of that.

LeSam

I even made my own Sprite class

to add more methods

hasherr

Really?

I made my own Screen classes because I don't like how LibGDX's Screen classes don't have an update() method

They only have a render() method, which bothers me immensely.

LeSam

I also remade the sprite class because I didn't like the Origins coords

it was reversed

hasherr

Oh that's dumb

LeSam

3:10 AM

in fact I don't like the Scene2d, I don't use that !

hasherr

So you could probably agree with me when I say that LibGDX is great for multiplatform and general game dev, but that it's best to hack it a little bit to make it work best :P

LeSam

yes, I fact, for me, libgdx is just a Graphic library, not a GAME engine (or should I say : libgdx is a bad GAME engine)

hasherr

I agree. I use it as a library, not a framework. I don't build my game around LibGDX, I build LibGDX around my game.

LeSam

true

me too, I only use graphics and sounds classes, the others is just bullshit !

hasherr

UI is terrible, manual screen switching is terrible

It does a lot of other things wrong as well

But it is without a question the best way to put your game on multiple platforms.

LeSam

3:14 AM

yes

without a doubt

hasherr

It's so cool how I can debug a game on my computer and then play it on my phone in less than 2 minutes

LeSam

another thing ! I don't know if it's libgdx or my devices, but The InputListener is so buggy when you use multiples fingers !

hasherr

Oh, it's tricky.

I learned a bit about it when I wrote a pong

LeSam

I use it good (with pointers and all), but It got some bugs

I thing it's from the devices

hasherr

Yeah. You know what's weird? LibGDX is the only thing I've ever seen where the developers recommend the nightly builds over the release builds

LeSam

3:17 AM

ahaha

I realised that when I used box2d

I had to download a script, inside there was a libgdx function that my eclipse couldn't find

hasherr

Yeah. Isn't that strange? I don't trust it, my developer instinct told me to stay the hell away from nightly when I saw it

@LeSam NOW THATS WHAT I CALL REVOLUTIONARY - libgdx devs

LeSam

ahah

The best things is ( I ) couldn't find the way to know which version of libgdx I was using

It's written nowhere

GENIUS !

hasherr

COMPLETELY MIND BLOWING

ITS SO MIND BLOWING THAT IT BLEW OUR USERS' FACES OFF

LITERALLY, THEY'RE EXPLODING OUT OF EXCITEMENT

LeSam

you have to remember the version when you clicked on the DOWNLOAD button, 7 months ago

GENIUS

hasherr

COMPLETELY REVOLUTIONARY

They should hire Johnny Ive to make it even more revolutionary

LeSam

3:21 AM

inside the libgdx RAR, there is a README, LICSENSE, NOTE files, none have the version number

GENIUS

hasherr

ReadMe - This is LibGDX. lol.
License - Lol don't steal
Note - lol

^LibGDX RAR file contents

LeSam

I FORGET

AUTHOR

CONTRIBUTORS

so, you don't know if you have the last official release or if there is a new one !

it's genius

genius !!!!!!

hasherr

I know we're bashing LGDX here, but seriously, I love it.

It has it's flaws, but they're easily forgiven due to how overridable it is.

LeSam

me too

:)

but seriously scene2d is totally a bullshit !

actors

what ?

hasherr

I don't use it.

LeSam

3:27 AM

action ?

hasherr

I use action for my custom UI

Ooohh, I had an idea. What If I wrote my own UI library for LibGDX.

LeSam

what the f* is that ? why actors ? do you think it's a mothfu movie ?

hasherr

LIGHTS CAMERA LIBGDX

LeSam

@hasherr you should keep your code for yourself !

hasherr

Huh?

LeSam

3:29 AM

because your code must be your secret

it's your thang !

hasherr

I try to keep things as open source as possible actually

LeSam

ok, then share it on facebook everywhere

hasherr

lol, not like that

Okay, so I'm really fucked right now.

LeSam

me, I can help someone give him some codes, but I can't give all my games codes

hasherr

I have this retainer that I have to wear on my bottom teeth because they shifted after I got my braces off

I haven't worn it in like a week and I'm wearing it now and it's getting sore and if I take it out I'll probably die

Because it's literally stuck on my jaw and it's going to hurt like hell if I even attempt it

LeSam

3:32 AM

how will you sleep with it ?

hasherr

I will sleep with it.

LeSam

what If you move it

in your sleep

hasherr

It won't do that.

LeSam

what if you dream about your mouth broken, and you wake up with a broken mouth ?

hasherr

Okay, I have to take this out

But I'm terrified of dieing

LeSam

3:34 AM

why you didn't put it early ?

hasherr

I put it on like 6 hours ago

LeSam

yes but why just 6

instead of a weak ago

hasherr

Oh you mean

Because I was lazy

LeSam

nevermind

hasherr

lololollololl

LeSam

3:38 AM

this one !

CS players

hasherr

haha

LeSam

only CS players can understand

hasherr

CS players are some hard motherfuckers, let me tell you that

You'd think that in real life they're all Navy Seals or something like that

LeSam

ahaha

hasherr

When in reality they're neckbeards renting their parents' basement.

LeSam

3:42 AM

ahahah

have you already finished an android game ?

hasherr

AHHHH

AHHHHHHHHHHHHHHHHHH

AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

IM DEAD

LeSam

?

it's a serious question

hasherr

I just took it out

Oww...

LeSam

I mean, have you already finished to make an android game ?

hasherr

It's technically done I guess

But it could use some polish

I get my debit card in a week or two, so I'll put it up when it's done

LeSam

3:45 AM

? what are you talking abou

hasherr

The screaming was when I took my retainer out

Everything else was about the app

@LeSam I can't put the app up until I have a way to get my developer license, which I need my DEBIT CARD for. :P

LeSam

ok

I have already mine

25$

hasherr

yeah

LeSam

(android)

Iphone it's expensive

hasherr

I could use my parents' card I guess, but I kind of want to make this transaction with my ownmoney

@LeSam It's like 100 and then more for each app I think

100/year I should say

LeSam

3:50 AM

well

if you develop for iphone there is no place for opensource projects !

hasherr

Nope. You also need an overpriced twitter machine to make them.

LeSam

you didn't heard about 'mini mac' ?

hasherr

wat

Whoa

I want one

LeSam

'low price' mac

I project to buy one

they are just a bit slower than real mac

just a bit

hasherr

That's still pretty fast

That's pretty cool actually

LeSam

4:01 AM

yeah

Do you know something about async thread

I'm following this code.google.com/p/libgdx/wiki/ApplicationThreading

is it the only solution with libgdx ?

hasherr

I haven't used it,, no

:(

LeSam

ok

I come back

Have you tried if some other image would work?

user92578

Acutally other image works...

user92578

9:02 AM

Acutally

user92578

hmm

user92578

What could cause this? The other file I tested was also a PNG file, but it's not created by me... Maybe Paint.NET does some weird stuff to PNGs?

Lasse

Maybe the importing library does not support something

user92578

What should my bit depth be?

Lasse

32

with rgba

user92578

9:05 AM

That did it... Paint.NET had set the bit depth to 8

user92578

but the sprite appears upside down... :D

user92578

My blending doesn't work?

Lasse

do you have blending enabled?

also which blending mode are you using?

user92578

nvm, I forgot a line

user92578

9:14 AM

glEnable(GL_BLEND)
glBlendEquationSeparate(GL_FUNC_ADD, GL_FUNC_ADD)
glBlendFuncSeparate(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_ONE, GL_ZERO)

Lasse

so it works?

user92578

yeah

@AlexM. Can growing a partition cause data loss in that partition

Alex M.

no idea

joapet99

Just want to get the ubuntu partition deleted and my windows partition grown

takes about 2 hours

they gave me a warning that this could make a data loss but I think that is mostly when you shrink a partition. Dont you?

Alex M.

11:09 AM

you will find out when it's done

joapet99

yep

Alex M.

if you actually had important data to lose you wouldn't have attempted it in the first place

joapet99

Actually it doesn't grow the partition it just copies my stuff over to another partition

Maybe I should had made a backup

Well well. To late to regret now

Some good games I can play while I wait?

Leggy7

3:05 PM

anyone could tell me how does float4 works? which fields do they have?

in hlsl

chances are that fields are r,g,b,a?

Alex M.

I think float4 is just made of 4 floating point components, and you can interpret them however you want

either r, g, b, a or x, y, z, something else

when working with colors, float4 would most likely be rgba

Leggy7

ya, that was my guess

but in this code you can see that it access a precise field of a float4

float4 controlMap = IN.color;

half4 col = lerp(rock, gravel, controlMap.g);

Alex M.

shrug never did shaders, no idea

hi

BlueBug

@LeSam Is that your real identicon?

LeSam

what do you mean by real ?

there is fakes ?

BlueBug

too cute to be randomly generated I meant. sick cute identicon >< ><

LeSam

it is a random one

:)

Alex M.

3:55 PM

I don't think identicons are "random"

LeSam

mine change everydays

Alex M.

Identicon

An Identicon is a visual representation of a hash value, usually of an IP address, that serves to identify a user of a computer system as a form of avatar while protecting the users' privacy. The original Identicon was a 9-block graphic, and the representation has been extended to other graphic forms by third parties. Invention Don Park came up with the Identicon idea on January 18, 2007. In his words: Releases The original Identicon source package 0.1 was server-side Java. Version 0.2 was cleaned up, added some documentation, fixed a color bug, added a cache, and a runtime jar...

BlueBug

" usually of an IP address" so in principle I could generate particular pattern I desire, if I know the algorithm of SE. dat's cool. Well then you had manually forced to have a cool avatar. There's a difference between a natural born beauty and plastic surgery pretty face.

Alex M.

or you know

just get a real avatar

BlueBug

not that getting plastic surgery to look pretty to cover something u significantly consider as a flaw is wrong but if you could choose to "born" pretty without plastic surgery, then why not; choose unique IP pattern to get pretty identicon.

Alex M.

4:00 PM

wat

BlueBug

I should get a fake identicon avatar, is what I am trying to say, I think.

GnomeSlice

One of the mods on gaming had a fake one for a while.

BlueBug

yeah I am getting myself identicon avatar now
