It's cool? No one told me

Stephane Hockenhull

01:11

I'm programming a popup window... it's not cool and not fun.

Chris McFarland

01:26

add confetti

Stephane Hockenhull

Chris McFarland

now ship it

Stephane Hockenhull

you're right, it's a little more fun now.

Chris McFarland

:D

I really loathe UI stuff with games

need a decent framework or something

Stephane Hockenhull

It's what I'm working on

and it's boring AF.

Chris McFarland

01:39

>_<

Sie

@StephaneHockenhull Looks like a PS1 or Dreamcast game now.

Stephane Hockenhull

but so far I got resolution-independent rendering, arbitrary shape clipping, multiple layers, 9slices with auto scaling, pixel shaders, distance field font rendering with dynamic font generation and atlas manager, automatic batch rendering, multi-window, drag-and-drop, zoom in/out (pretends resolution is higher/lower), multi-touch, multi-pointers (more than 1 mouse cursor / wiimote), multi line textbox, CSS formatted text rendering, and all the UI elements are 3D

Mouse clicks are 3D ray-casted. It's not just a 2D canvas. Also supports full matrix transform on the elements.

What's missing is all the UI gizmos themselves (scroll bars, radio/checkbox/pushbuttons, list/tree view, menu, etc).

Sie

01:54

Oh wow. 007 Agent Under Fire hasn't held up well at all.

How do people play with these forsaken controls?

Chris McFarland

@StephaneHockenhull sweet, sounds comprehensive so far. yeah, input fields and UI manipulators sound good

Stephane Hockenhull

Now dealing with a weird bug where the gpu context returns a size of 0x1 even though the code put the proper size into the structure.
Dunno if it's memory trashing or some other part that changes it when the window is mapped.

TheMuffinCoder

Getting progress done with my terrain :D

Stephane Hockenhull

gpu context is the FBO which is also the window's client area. resizing one resizes the other and there might be some weird issue with X11's networked architecture .

Stephane Hockenhull

02:20

ah F me.....

I was using the wrong gui root object to transform the local coords to screen coords.

Sie

02:59

Alright. I'm going to play some My Word Coach and you guys had better be impressed. The box says so. @Almo

Stephane Hockenhull

lol

Almo

03:26

:D

over the long haul it advances through more complex words. we had a phd in linguistics working on the game

Sie

Does it? Cool.

Oh ya it's mentioned on the box too.

redesign the previous one that followed the arrow around. This is one is much cleaner me thinks

Uri Popov

08:39

oh btw for mobile devices should I worry for any aspect ratios other than 16:9 and 4:3

user92578

09:26

morning

Leggy7

good day

are you okay tyyppi?

user92578

what? yes

Leggy7

hangover on the way?

user92578

nope

Leggy7

ahah

did you celebrate somehow yesterday?

user92578

09:28

naw

Leggy7

not even hanging out with some close firend?

do you have some of your daily life friend who follow you closely on you development experience?

user92578

not really, but I'm sure I'll get some more interest from my friends now

Leggy7

:)

shit is getting serious ah?

user92578

I don't talk a whole lot about the game with my irl friends, I've shown a couple guys some of the game

user92578

but now that I've posted on facebook and stuff I'm sure more are interested

Leggy7

09:32

uh tyyppi

I want you ask you for an opinion on a concern I have

user92578

aight

Leggy7

I'm doing balancing stuff for my game and I build some custom inspector to allow me to handle numbers and shit for difficulty purpose

I was wondering if you think could be viable to handle difficulty scale this way:
I have some basic value for player starting hp, enemies starting hp, damage, etc. Then I have my world which increase difficulty every room you walk away from the starting one. To keep the game challenging I thought that every room you walk enemies stats get multiplied by a coefficient which is different based on difficulty level you're playing in

so for instance a thief enemy which has 20hp in the first room, will get multyplied and in the 9th room will be something like 20 + 20*0,3*9

this is a kind of linear increase for enemy stats

I was thinking to have the player progress non linear so that it relys on player skill whether to stay close or away from enemy curve

you think this way could be solid?

Chris McFarland

sounds okay

Jon

09:47

What is 0.3 a constant?

Leggy7

I kinda liked this way but since it is a pain to adjust numbers and shit some killing opinion could be important

yes, it is a constant I define in the editor for balance sake

Jon

You can do it better

Bálint

Hello

Leggy7

could you tag me in your reply because I'll be called by my kids in a minute :)

Uri Popov

hi

Jon

09:50

Haha well you asked for a comment to ruin it

It will work fine

Chris McFarland

@Jon I just found some nice text outlining

Leggy7

ahahah

fine :)

Jon

New?

Chris McFarland

github.com/n-yoda/unity-vertex-effects

Jon

Yeah that is old

Chris McFarland

09:51

:(

New to me! :D

Jon

It overlays 60 text meshes per outline

Chris McFarland

oh snap lol

Jon

It is pretty shitty

Uri Popov

dammn

Jon

Text mesh pro is now 95

Out of beta

Chris McFarland

09:53

yeah TMP is nice

it doesn't have as many soft outline options though, unless I'm just blind

Jon

I only played with it a bit

Uri Popov

I got no comments on my new tutorial message so I'm going to ask again giphy.com/gifs/26ufeqFLZXxuqxbC8

Chris McFarland

Looks like some text

Uri Popov

well the panel and the button are going to get swanky sprites and so on I just think this is super clean. Way better than the text following the arrow itself

Bálint

@UriPopov What are you working on exactly?

Uri Popov

10:06

a mobile board game

Bálint

@UriPopov Could you make it come up a bit faster?

Adn less transparent, it's hard to read

Uri Popov

like I said its going to get a cool background this is just the default unity panel as for the speed I sure can

Bálint

@UriPopov Ok

It's just frustrating when you need to wait for the tutorial text to come up

Especially on a mobile game where you don't want to spend your life on waiting for such things

Uri Popov

well the current animation length is 0.45s. I think that because I made the gif with a low framerate it might seem slower.

Bálint

Is it faster than on the GIF?

Uri Popov

10:15

the motion is smoother for sure as for the speed I think its just a bit faster cause of the low frame rate gif

I nudged it down to 0.4s

Bálint

@UriPopov Could you upload a gif with 60FPS

?

Uri Popov

gonan be one big ass gif

Bálint

@UriPopov That's how it works sadly

Uri Popov

actullay this time it turned out <2mb somehow

Bálint

That looks good

It's so small because 90% of the image doesn't change

user92578

10:22

the arrow needs to change though, it doesn't really stand out as it is

Bálint

@Tyyppi_77 Outline

user92578

yeah, perhaps

user92578

a color change could be used with an outline

Uri Popov

outline what now ?

Bálint

Or a white (or bright) arrow with a black outline

user92578

10:24

the arrow

Bálint

That usually solves everything

Uri Popov

outline it when it reaches the target or just always ?

Bálint

Always

user92578

always

Bálint

Look at your cursor

It also has an outline

So you don't lose it

Uri Popov

10:25

ahhh k I get it

cool tip guys

user92578

the tutorial looks good though

user92578

I really like the arrow otherwise

Bálint

Yeah, in most games it just jumps to the target instantly

I added some stuff to the server->client messaging in my chat-game engine. Could one of you help me test it?

Uri Popov

10:45

added a outline and some glow

user92578

looks a lot better

user92578

glow could be even bigger

Uri Popov

I think I'll keep the glow as is for now. But the outline idea is the bomb thanks again guys

Jon

The rotation should be lerped

Make it look more professional

user92578

It's lerped, isn't it?

Uri Popov

11:01

its a Quaternion.Slerp

or do you mean that it immediately "snaps" when there is a new target ?

better?

Jon

Yeah I think so

Uri Popov

just lowered the damping of the Slerp

Bálint

11:22

@UriPopov NP

My cat ate the same thing for lubch as me. And I'm not even sure if he ate smaller proportions

Is it normal when a cat eats cheese with french fries?

Uri Popov

no

Source: I have had a cat for 10 + years

Bálint

Anyone has 2 minutes?

And can go to a site

user92578

sure

Uri Popov

yep

Bálint

http://178.48.120.214

And enter the same thing to the address bar

Uri Popov

11:33

you better not hack me

Bálint

@UriPopov Don't worry

Uri Popov

11:47

whom ever came up with 4:3 should be publicly lynched and hanged

Bálint

@UriPopov I have a 4:3 monitor

Uri Popov

why

Bálint

Because it's old

Very old

In fact I should probably change it

But that can't happen without me changing the video card too

Skyrim is the latest game I can play with a constant 60fps

In fact it's not even 4:3

It's 5:4

Almo

12:27

@UriPopov 4:3 is from... the 1940s?

Uri Popov

iosres.com tell that to apple

Bálint

@UriPopov That's not 4:3, It's 3:4

Actually, they're the same thing, as you can turn it around

user92578

Whoa, you can do int array[12] = {[0] = 1, [4] = 2, [8] = 3}; in C

Uri Popov

its 3:4 when its in portrait mode

Almo

NTSC

NTSC, named after the National Television System Committee, is the analog television system that was used in most of the Americas (except Brazil, Argentina, Paraguay, Uruguay and French Guiana); Burma; South Korea; Taiwan; Japan; the Philippines; and some Pacific island nations and territories (see map). The first NTSC standard was developed in 1941 and had no provision for color. In 1953 a second NTSC standard was adopted, which allowed for color television broadcasting which was compatible with the existing stock of black-and-white receivers. NTSC was the first widely adopted broadcast color...

yeah, looks like it comes from 1936

Uri Popov

12:40

well fuck 1936

worst year ever

Jon

That depends on your perspective

Uri Popov

why did Unity start throwing this all the time

Assertion failed on expression: 'SUCCEEDED(hr)'

for about 35s then stopped ?

user92578

umm that looks like a WINAPI thing

Uri Popov

fuck if I know but its gone now. THe game wasnt even running when it happened

Jon

12:56

Unity.

user92578

I have that bookmarked

Q: How likely will I be able to get a job in game design with a masters in computer programming?

I'm currently attending college and am almost finish with my Bachelors in Computers science.I plan on getting my masters in computer programming in hopes that it will help me get into game design.

game-design programming career jobs

Bálint

I'm also curious why the question I linked earlier is marked with both opengl and javafx

Alexandre Vaillancourt

@Tyyppi_77 I think a proper comment for him would be "we won't give specific implementation that has been tested, we don't do this here"...

@Bálint Dunno, maybe he'll do OpenGL calls from withing the JavaFX app?

I don't know java and all this stuff :P

Bálint

13:24

@AlexandreVaillancourt JavaFX and OpenGL can't work together

He simply watched an openGL tutorial on reading the .obj file and he doesn't know what OpenGL is

Alexandre Vaillancourt

Probably :) You should edit out the tag!

Bálint

In fact, I'm 99% sure he watched this one:

OpenGL 3D Game Tutorial 10: Loading 3D Models

►

Because the code is the same

Alexandre Vaillancourt

So he did not write anything :P

Bálint

@AlexandreVaillancourt Nope

Alexandre Vaillancourt

@Bálint If it's not possible to draw a 3d model in JavaFX, I suggest you write an answer :) Starting an answer with "You can't." is very fun :)

Bálint

13:35

@AlexandreVaillancourt There's nothing such as impossible in programming

If you have a text based display at least, then you can draw 3d models

I usually just use 2d javascript to draw 3d models

Alexandre Vaillancourt

Right, he can write his own 3d rendering pipeline :P

Bálint

This: codepen.io/mcdorli/pen/PzjKqK and this: codepen.io/mcdorli/pen/LkdoZo

THe last one is more complex

Still, shorter than in WebGL

Alexandre Vaillancourt

Nice!

Bálint

OpenGL is just a rasterizing API, it's not 3d

You need to create Every step except rasterization

Alexandre Vaillancourt

Yeah

Bálint

tom_mai78101

14:43

Hello. Does anyone know how to apply rotations in quaternions to objects?

Alexandre Vaillancourt

You'll have to provide more details. Do you use a framework?

arda

@AlexandreVaillancourt +1 on the question.

If you are on unity, use euler.

tom_mai78101

Not using any known framework.

I'm just playing around with devkitARM and Citro3D, and writing games for emulators.

It seems to be using OpenGL in C++

Alexandre Vaillancourt

My guess is that you'll have to convert the quaternion to a matrix somehow at some point and use the matrix to rotate the object.

Almo

I have to say this again

kongregate.com/games/molkman/caesars-day-off

what a fucking great little game

even has multiple endings

tom_mai78101

14:51

@AlexandreVaillancourt No direct calculations? Ok.

Sie

The Humongous Entertainment/Pajama Sam video is finally done.

Humongous Entertainment - Pajama Sam

►

Alexandre Vaillancourt

Not to my knowledge; to transform a vertex, you multiply it by a transformation matrix.

Nothing prevents you from keeping your rotation information in a quaternion until the last moment, though :)

@Almo That's not fair, I'm trying to work here :P

Almo

:D

tom_mai78101

15:08

Alright, so the process is:

1. Do whatever necessary rotations you want in quaternions.
2. Convert quaternions to a rotation matrix, R.
3. Do whatever position delta calculations you want and apply it to Mtx_Translate() to get translation matrix, T.
4. Get model matrix, (RT).
5. Pass model matrix into vertex shader.
6. Do MVP, so it is [Vertices * (RT) * V * P] =output.

Correct?

Kevin van der Velden

Pretty much

tom_mai78101

Thanks. Finally!

Bálint

Why are quaterions better again? I don't really remember

Almo

they don't have gimbal lock

Kevin van der Velden

Versus euler angles, that ^. Versus matrices they've got 4 floats rather than 16 and are easier to calculate

tom_mai78101

15:15

@Bálint They are like paint. You mix then up by the weight value of the 4 facings a 3D object model can have, and you just need to consider how much facings it needs to be applied to get the right orientation facing.

Kevin van der Velden

Erm, no, not really

arda

quaternions are too confusing :/

Jon

Learn matrix math

Sie

@Almo You have some explaining to do.

Bálint

@Sie What's this

tom_mai78101

@Sie Seriously, what's this?

Jon

15:24

It's not a flag

@Jon I had to read it twice!

Bálint

15:27

@Jon That works in (I guess C) too?

Almo

:D

Jon

Releasing in a few days.

Took the bonus level out. At least for now.

Need one more sound pass and a video

arda

Is it the lack of ==?

user92578

yes

Sie

Did you make all of those sound effects? I can only imagine you sitting in a cold dark room making freakishly squeaky voices for your video game.

Bálint

15:29

@arda Yes

Jon

Yes.

user92578

I actually really like that feature in C++

Bálint

In some languages assigning a variable to a value returns that value

For example JS

Jon

And it's filtered in audacity lol.

user92578

Allows writing code like if (CEntityPlayer* player = level->GetNearestPlayer(m_Position)) { }

Bálint

15:30

This pretty much works in every language, but it's especially irritating in weakly typed languages

Jon

You serious?

Sie

Of course not lol.

I still kind of wonder where that trend came from. A lot of mobile games have that sort of squeaky voice in them for sound effects.

Jon

I was wondering if there was a pitch bug or something lol

It is easy

Record voice. Raise pitch.

Sie

Ya.

Jon

Worms and lemmings did it

Sie

15:33

Man I really want to try doing some mobile games but all of my ideas really work best in a FPS/3D setting and that is not a good fit for mobile at all.

Almo

@Tyyppi_77 don't do that

It's not legible code

Jon

That's why I design around mobile to start

user92578

It has it's downsides, but the reduced scope is a bug plus

Almo

it's not a big plus

user92578

it is

Almo

15:34

it's compacting code for the sake of saving lines, and that's not a good idea

Jon

It's a bad habit

Almo

like, this would not pass code review here.

Jon

Haha

Almo

a lot of places won't allow this usage, it's hard to read for someone who did not write the code.

Jon

We should make a site called hotOrNotCode

user92578

15:36

void Foo()
{
	CEntityPlayer* player = level->GetNearestPlayer(m_Position);
	if (player)
	{

	}

	...

	// Oh, we have a pointer to the player.
	player->Bar();
}

Jon

Paste code snippet and get other coders to rate

Have a top 10 hottest code snippets

Almo

^

Sie

You won't believe this hot new trick that this coder uses!

Jon

Line 7 will blow your stack

Sie

Find out in page 96. Code reviewers hate him!

user92578

15:38

void Foo()
{
	{
		CEntityPlayer* player = level->GetNearestPlayer(m_Position);
		if (player)
		{

		}
	}

	...

	// Oh, we have a pointer to the player. Compile error
	player->Bar();
}

user92578

That just looks awful to me

Jon

@Almo when can you submit me a ios test build?

Almo

maybe over the weekend

I don't really understand why you're writing it that way

you're not solving the non-assignment in expression the right way

user92578

The issue is the scope of the player variable

user92578

Using the if-pattern, that won't be an issue, you can't access a NULL player

Almo

15:40

why is player->Bar() outside the if(player)

PearsonArtPhoto

^

user92578

because the code has a bug

Almo

void foo
get player
if null return
do stuff

PearsonArtPhoto

Or for that matter, outside the inner brackets...

Although it should be as Almo mentioned.

user92578

Yes, but you can't do that in all cases

Jon

15:45

Does your name have something to do with Elmo?

Bálint

Almo (god)

Almo was in ancient Roman religion the eponymous god of a river in the vicinity of Rome. Like Tiberinus and others, he was prayed to by the augurs of Rome. In the water of Almo the statue of the mother of the gods, Cybele, used to be washed. He had a naiad daughter named Larunda. == References == This article incorporates text from a publication now in the public domain: Smith, William, ed. (1870). "Almo".

Q: What is the difference between opengl and GLSL?

I recently started programming with openGL. I've done code creating basic primitives and have used shaders in webGL. I've googled the subject extensively but it's still not that clear to me. Basically, here's what I want to know. Is there anything that can be done in GLSL that can't be done in pl...

opengl glsl

Almo

@Tyyppi_77 why not? and if not then null test again

alan2here

I will work on it now if it is.

user92578

If the function needs to do something other, after accessing the player

Bálint

@alan2here C is not the part of C++

user92578

15:49

I don't think the C/C++ metaphor is a good fit here

Bálint

Yeah, you should use something more fitting, for example pencils

alan2here

ok

Bálint

You can draw an image using only a lead pencil and same for colored pencil, but you can use them together

alan2here

as in a subset of everything possible in C++, if you choose the correct subset OFC, is C

good analogy

like a graphite peincil is just a particuar color of coloring pencil?

I thought C++ being build on C would be more relevent to this domain

Bálint

@alan2here Kind of

There's some difference but yes

@alan2here BTW, fract(sin(p)*10000.) doesn't return a random value, it returns a pseudo random value

alan2here

15:55

I could just cut that paraghraph

Bálint

boallen.com/random-numbers.html

alan2here

lol, ok, will correct, the random/(sudo random) distinction is one hell of a rabbit hole

"PHP rand() on Windows Bitmap" is really awefull

I remember the one in QBasic was very bad too

ok, fixed
