@IcyDefiance you there?

Icy Defiance

@Almo I am now

Almo

just started a game with the donut

Icy Defiance

01:08

finally got vim working the way I want

and it's awesome

only thing I'm missing is debugging integration, but I'll just make gdb work for now

Pip

@IcyDefiance very cool

@Wardy I think so too

@IcyDefiance cool

Chris

02:13

dammit Unity, dunno why Alt+[1-8] doesn't work on Linux

Alt+1 works on Windows, does nothing on Linux

I can't do Ctrl+1 on Windows

Cmd+1 works on Mac at least

can't even do Ctrl+1 on Linux, that's some bs lol

apparently is a known issue since 2013
that's cool

Sometimes being smart actually makes you look dumb.

Today I told someone that the primary colors were red green and blue.

Maybe they just figured that since I was wearing a Pi day shirt that I was right though. LOL

Icy Defiance

heheh, this is where I get to be extremely pedantic

normally pedantic people say there are two sets of primary colors, one for additive color and one for subtractive (RGB vs CMY)

but really, any small set of colors that can be combined to create a useful range of colors could be called "primary colors"

3 colors are normally used for humans because our eyes are trichromatic, but for some animals and even some humans that doesn't hold true

even for normal, trichromatic humans, there's a set of "psychological" or "natural" primary colors based on how our brains (supposedly) process color. explanation here if you're interested: en.wikipedia.org/wiki/Opponent_process

MickLH

@IcyDefiance ta da

Icy Defiance

:O

would you know how to make cmake link to an already compiled library?

MickLH

I would just jam it into the Makefile like a fucking bastard

Icy Defiance

the makefile is generated by cmake, though, and won't be going into my git repo XD

MickLH

awwww manualll readingggggg ewwwww

@IcyDefiance how is the library compiled?

If you have a static library it's pretty easy, but for dynamic there's some annoyances I think you have to deal with

Icy Defiance

I can do static. It's glfw, so it has both options.

MickLH

04:54

well I'm sure there's a CMake way to do it, but eventually the C++ compiler needs to get "-lglfw" on the command line

then it will link "libglfw.a"

and you can handle visual C++ with a #pragma

Icy Defiance

okay so that much is right. it's complaining that it can't find the library, though, so I just need to figure out how to point it to the right directory.

Aidan Mueller

@IcyDefiance Look better this time?

I think the ear may still be a bit back, but whatever.

Icy Defiance

ooh yeah definitely better

Aidan Mueller

@IcyDefiance Here's a difference gif.

MickLH

05:13

soundcloud.com/jesus-exe/chop-spy-hat

Don't expect anything more from full synthetic, he's dead.

Icy Defiance

whoo got it to stop complaining about not finding the library. now it just says undefined reference. XD

MickLH

lol ouch

either you need more libraries, or you need to compile something differently

Sword

Icy Defiance

trying to make the thing output the compiler command it's using...

MickLH

@IcyDefiance are the references missing from something that you have obviously linked, or something that you've obviously not linked?

Icy Defiance

05:22

from something I (supposedly) linked. glfwInit(), glfwCreateWindow(), etc.

MickLH

Ok then make sure the static library actually exports anything

It's all too easy to not define some macro and end up with an empty .a / .def

Icy Defiance

05:40

okay, it seems that cmake puts things into an objects.a file, which is a lot smaller than what glfw is. I have no clue if that makes sense or not.

new idea. gonna generate VS files and check the linker properties there

at least I know how to work with that

Icy Defiance

06:00

okay I still have no idea

OH WAIT NO I GOT IT

but it took a windows specific measure...which means the only way to fix it might be compiling glfw with my project >.<

okay so I think the problem in the end is that mingw doesn't like opengl32.lib

Aidan Mueller

06:22

I'm working on a spaceship.

The manufacture hasn't painted it yet, so the metal is still exposed ;)

Mutch95

are you guys still working on that project?

Icy Defiance

dunno. one day no one logged into the hipchat room and everyone just stopped talking about it ever since. I have no idea why.

aidan wasn't part of that though

MickLH

I left a message on that room the other day lol

Icy Defiance

yeah, and at least you still exist. I haven't even seen hobo in this room for the last few weeks.

MickLH

lol I think I kinda disappeared for a moment too actually

Icy Defiance

06:29

dunno what pip is doing either, but he wasn't going to be much help anyway until we can start on gameplay

Aidan Mueller

@Mutch95 What project?

@MickLH Why are you removing everything?

Icy Defiance

@AidanMueller a bunch of GDSE people teamed up to make an awesome game

then one by one they all quit without doing any work, except for Mick, Hobo, and myself, lol

MickLH

lol oh I thought that was a period after my name

Mutch95

hahaha

Aidan Mueller

Is it a Unity project?

MickLH

06:31

like, except for Mick. "Hobo and myself, lol"

Mutch95

nope

it was confusing from the beginning

Icy Defiance

@AidanMueller no, when we started Unity free didn't support the kind of graphics we wanted

so we started with Monogame, but that wasn't good enough, so we started on our own framework instead

Aidan Mueller

OK because if it's still active.

I could jump in.

But then again, I am working on pioneer now so...

Icy Defiance

yeah, I've kind of given up on that project

Hobo or Mick will have to revive it if it's going to go anywhere

anyway, down to one error now: undefined reference to `__ms_vsnprintf'

and google is not helpful there

MickLH

lol

that's the dreadful kind of linker error

I have nightmares about linker errors like that on a regular basis

Actually maybe only a couple times in my life, but the depth of the trauma makes it seem like it's a recurring thing

Aidan Mueller

06:35

I have begun to just rely on my package manager setting everything up correctly.

The Unix/Linux build system is nice.

Icy Defiance

> It's a mismatch between 2 subtly incompatible MinGW development environments: one produced and supported by mingw.org (which this list is about), the other MinGW64, a different project.

if glfw was compiled with MinGW64, that would explain everything...but it would also mean I need to compile glfw myself :'(

MickLH

lol lucky strike, your karma is good and your soul is blessed

@IcyDefiance give up on elegance, cry with joy that it might actually link and produce an executable

Then you can start figuring out why it immediately crashes!

Icy Defiance

awesome!

the "hilarious" thing is it works perfectly now when I make VS do the compiling

just doesn't work with mingw

MickLH

I think that's the rule of thumb with whatever was used to compile your OS

If you can't tell by my humor, the open source compiler tools kinda torture me on windows

I always end up just using VS on windows unless there are binaries ready to go

Icy Defiance

yeah, I just want to be sure my code will compile on both windows and linux at any time, depending on what parameters get passed to cmake. mingw should put that kind of constraint on me without actually installing linux...at least in theory...

MickLH

06:42

Cygwin might be easier

At that point, you arguably are just installing linux on your windows :P

Icy Defiance

nah just gcc :P

MickLH

lol but, it'll depend on a bunch of shit

and will basically pull in everything necessary (except the kernel) for a command line install

it's kindof annoying downloading a lot with no way to skip even though it's not really that necessary for being necessary

or "a lot" I mean, a few dependencies

but still, it always adds up for me when I go to actually use it for something

shit I told myself to go to sleep at a reasonable hour tonight

Goodnight

Icy Defiance

compiling glfw myself works. yaaay.

Aidan Mueller

06:57

@IcyDefiance You may want to look at clang.

Icy Defiance

I have that installed for YouCompleteMe. No idea what it does though.

Aidan Mueller

It's a compiler.

It's like gcc, but cooler :P

I think it's faster, and gives better error messages.

It also has a modular compiler system, so to add a language you just write a new abstract syntax tree generator.

It's what emscripten uses.

It's part of the LLVM (low level virtual machine) project.

Icy Defiance

I might check that out, then

Aidan Mueller

I still use GCC, but it sounds like it might be the future.

@IcyDefiance It is gcc compatible, so you can basically just drop it in place of gcc if you want to test it out a bit.

OK I'm going to bed now. Leaving this awesome song here:

SpicyWeenie

09:11

anyone work with texturing a simple quad in opengl? My texture keeps repeating itself

Kevin van der Velden

What are the UV coordinates of the quad?

SpicyWeenie

0.0f, 1.0f,
0.0f, 0.0f,
1.0f, 0.0f,
1.0f, 1.0f

Kevin van der Velden

It shouldn't be repeating itself then, huh

SpicyWeenie

and my verts are

-0.5f, 0.5f, 0.0f, // V0 : Top Left
-0.5f, -0.5f, 0.0f, // V1 : Bottom Left
0.5f, -0.5f, 0.0f, // v2 : Bottom Right
0.5f, 0.5f, 0.0f // v3 : Top Right

Kevin van der Velden

Are you using shaders or the fixed function pipeline?

SpicyWeenie

09:13

shaders

Kevin van der Velden

Post those? =p

SpicyWeenie

the shaders?

Kevin van der Velden

Yeah

They can do nearly anything and it's not the UV coordinates so =p

SpicyWeenie

layout (location = 0) in vec3 position;
layout (location = 1) in vec2 textureCoord;

out vec2 texCoord0;
out vec3 color;

void main()
{

gl_Position = vec4(position, 1.0);
texCoord0 = textureCoord;
color = vec3(position);
}

Frag

in vec2 texCoord0;
in vec3 color;
out vec4 outColor;
uniform sampler2D textureSampler;

void main()
{
gl_FragColor = texture(textureSampler, texCoord0 + color.xy);

Kevin van der Velden

Try without adding color.xy? That seems the likely culprit

SpicyWeenie

09:16

Thats what I was thinking....

And that was my problem

:P

Kevin van der Velden

Kinda sucks porting from LWJGL to OpenGL

Sword

@KevinvanderVelden got that working.. Instead of updating the y position of car , I scrolled the background at that speed..

Chris

@KevinvanderVelden that sounds awesome lol

Kevin van der Velden

They really need to fix the link color

Chris

I had a Stylish script for a while that underlined the links, cuz yeah

Kevin van der Velden

09:43

I've made one with a better color, just haven't installed it on this machine

Chris

too much effort between machines and formatting harddrives and the like lol

Kevin van der Velden

userstyles.org/styles/103649/make-links-identifiable

Found it!

Q: Can we get a hyperlink style for chat that is less subtle?

I'm open to suggestions as far as whether we should change the color, underline links, or both, but as it is it's a little too subtle for less than perfect monitors and viewing angles.

Chris

okay installed, thank you lol

/bookmarked

Kevin van der Velden

There, also a thing to do the same to the star list, and @Pip uploaded one to userstyles.org that does both but it applies to all chat sites on stackexchange

Which I don't like cause most have perfectly fine link colors

Chris

yeah

Sword

10:57

a question; this works fine except that the speed doesn't limit itself and keeps on increasing indefinitely..

if (mainVelocity.y<= maxVelocity) {
            mainVelocity.y += acceleration *deltaTime;
            mainPosition.y += mainVelocity.y*deltaTime;
        }

        else{
            mainPosition.y += maxVelocity*deltaTime;
        }

OMGtechy

11:48

@Sword so what's the question?

Sword

I need the speed to be limited

but it keeps on increasing..

even beyond max velocity

OMGtechy

So what have you tried to determine the source of the issue?

Sword

well ; I used a similar kind of code before and it worked perfectly fine.. I changed the value of max_velocity from 25 to 3 and then to 0.3 ; I even removed deltaTime to see how it behaves.. Without delta time ; it accelerates real quick..

/i forgot to mention; here's the code that updates:

currentBgY.y -= MainCar.getPosition();

OMGtechy

it will yes, factoring delta time generally slows things down (as you're taking the speed per period and multiplying by how many periods there have been; typically a number close to 0)

Have you stepped through it with a debugger?

Sword

nope.. Haven't got much experience with that.

OMGtechy

11:58

Well, now is your time to learn :D

Sword

I usually debug using Gdx.app.log to display msgs to see if it reached a certain portion

OMGtechy

Debuggers are a very powerful tool, especially when the code you write appears to do one thing, but actually does another

and that's a start yes, but a proper debugger will help you here

Sword

"usually" means since last week :D

OMGtechy

aha

Sword

I am using Intellij and it has a debugger

OMGtechy

11:59

Good

Sword

If you know of any good and easy source for debug tutorials ; u could link that.. No need for you to take the trouble to explain :)

just a question ; the equations look fine , right?

OMGtechy

Not enough information really, it could be a number of things.
For example, I don't know the type of any of the variables, I am guessing you're using Java, I don't know what units you're using (if any), and so on

it might be working just fine, but the speed is set too high and the cap too low

quickly googling gives loads of information about how to use the debugger in IntelliJ

two things you'll want to look up; breakpoints and stepping

Stepping: jetbrains.com/idea/help/stepping-through-the-program.html

Breakpoints: jetbrains.com/idea/help/breakpoints.html

Sword

12:19

@OMGtechy thanks.. The unit is pixels.the background is 480*800. and it scrolls vertically

Veritas

yo

JohnPoison

@Veritas yo

Veritas

wow talk about ugly

template <typename... Args>
Atom(Args&&... args) noexcept(noexcept(initialize(std::forward<Args>(args)...))
{
        initialize(std::forward<Args>(args)...);
}

JohnPoison

@Veritas so what's so ugly?

Veritas

duplication.

JohnPoison

12:33

ugly to duplicate, but beautiful that you get compile-time check

not mention what beautiful things variadic templates allow to achieve

Veritas

yes but they could probably achieve the same with less bloated syntax

(talking about the noexcept part)

JohnPoison

agree

Sword

12:59

@OMGtechy found the problem.. I was subtracting the position twice i.e

mainPosition.y += mainVelocity.y*deltaTime;

currentBgY.y -= MainCar.getPosition();

the solution was just to replace "+=" to "=" .. because the background update automatically deals with it..

OMGtechy

13:42

@Sword glad you worked it out :D

Almo

13:57

I'm so glad I ignore reviews and websites when picking movies.

I just saw a decent one the other day, and it fooled me pretty well

quick check of review sites show people saying "Big Twist!!!"

had I known that, I'm sure I would have spotted it.

Lasse

14:29

I also usually ignore all the reviews about movies and games I am interested in, I want to see it how it was ment to be seen

if I read any reviews beforehand it will affect how I percieve the content

Almo

yeah

I also try to avoid trailers

they usually give too much away

I saw Regarding Henry cold, and really liked it. I saw the trailer later... I'm sure I would not have enjoyed it as much having seen the trailer first.

Ah right.

You're one of those guys.

Hjorthenify

I did ask for a transfer to HTX after the first year, but I wasn't allowed -.-

William 'MindWorX' Mariager

15:47

Ah that sucks. I've really enjoyed HTX. Last year for me too. Preparing some stuff for one of the last tests we're doing before we begin preparing for exams.

Hjorthenify

Ahh nice

Yeah I would have enjoyed HTX far more than STX, but STX was MUCH closer, but I regret it after the first year :P

William 'MindWorX' Mariager

Hehe

Yeah, I think the transfer window is only like the first semester.

Hjorthenify

Half

And it is only because you are mission ONE class the first year

William 'MindWorX' Mariager

I'll (hopefully) go to DTU this summer

William 'MindWorX' Mariager

Is it hard to get in over there? There isn't even any requirements in AAU. I just have to pass. And even if they do instate a requirement this year, my average without bonus is 11.3 so far, so I doubt I'll have any problem getting in.

you can assign them to a name like any other value

Has anyone noticed that the WYSIWYG part of the WPF designer in VS 2013u2 is a bit broken?

When I make a WPF form it doesn't look the same when I launch the program.

I'm not using any special themes or anything. Just regular Windows 8.1 theme.

I never use the visual designer for XAML.

Yeah, me neither. I was demonstrating it for some of the kids I was tutoring.

I dunno how long it has been an issue. Last time I used the designer was in 2012.

I had hoped to compensate it with spellcasting, but I should've checked my aptitudes for magic first; Trolls are absolutely terrible at it. I have literally the lowest possible aptitude for spellcasting.
