also has a great joke on google.com if you search for "recursion"

Hjorthenify

Heh :)

That will confuse somebody :P

Almo

:D

I once marked an SO (or gdse) question about recursion as a duplicate of itself

it took a while before someone noticed that. :)

Hjorthenify

:P

Almo

Funny thing about recursion is when you are writing a recursive function, you hit the part where it calls itself, and you say in your head "ok this function returns... I'M NOT DONE WRITING IT YET"

So true :P
Recursive functions are hard to debug though

@Almo I love this moment :D

Almo

:D

Hjorthenify

Did I break something? It doesn't say "@Almo"

Almo

:D

user92578

Almo

:)

Hjorthenify

14:06

Also I was kinda scared that my recursive experiment would break the chat xD

Almo

:)

JackFrost

haha yeah I think you might get into trouble if you managed to recursively quote yourself

Hjorthenify

Haha yeah :P

user92578

14:22

look what I found xD

user92578

Hjorthenify

Looked so much cooler then

user92578

ha!

Hjorthenify

80% of my time coding challenges are finding the correct terms for the code -.-

user92578

Grass is the only thing left unchanged

user92578

14:25

Well, kinda

user92578

Current grass has another layer underneath

Hjorthenify

What about the ladder?

user92578

Colouring has changed

Hjorthenify

Ah

user92578

But otherwise it's the same

Hjorthenify

14:26

Man I need to get back to my game

Haven't touched it for 2 weeks

user92578

oh that's a long time

Hjorthenify

My programming has become far more serious since Uni

user92578

Well I guess I had like a month break in GunHero before starting the current iteration

Hjorthenify

The time I would normally code for fun has become time where I practice my coding skill

That's some sexy window movement right there.

A: Swap two variables without using a temp variable

First of all, swapping without a temp variable in a language as C# a very bad idea. But for the sake of answer, you can use this code: startAngle = startAngle+stopAngle; stopAngle = startAngle-stopAngle; startAngle = startAngle-stopAngle; Problems can however occur with rounding off if the tw...

user92578

Thanks!

Hjorthenify

Interesting method

Not very useful though :P

user92578

yeah :D

user92578

I wonder if one could do that in C++ with pointer arithmetic

user92578

One probably shouldn't, but...

Hjorthenify

14:30

Its not going to be faster regardless..

Also you got std::swap

user92578

yeah

Almo

pointer arithmetic always strikes me as asking for trouble

Hjorthenify

Pointer arithmetic is what makes C++ fun! :D

Lokkij

I have a feeling my ImpProg teacher loves pointer arithmetic.

Hjorthenify

Everyone loves pointer arithmetic.

14:31

@Tyyppi_77 Yes. Don't

(Yes for certain values of yes, including but not limited to: Same size datatypes, not running into undefined behaviour for your specific compiler (null pointers, out of memory pointers, pointers outside of allocated space) (some undefined behaviour can not be avoided in doing this, beware raptors) )

Almo

doing sequence reverser without using the stack memory nodes is hard

(acheivement)

Hjorthenify

First iteration of in-place quicksort complete :) Now I just need to make it extendable

Pip

14:46

eyo

Hjorthenify

Ayo

Pip

Particles!

Lokkij

@Almo That sounds.. very challenging, yes. Very challenging.

Moses Aprico

15:01

ugh power out

Almo

@Lokkij it is, man. it is. still stumped on it (remember if you figure it out don't tell me)

Hjorthenify

... I'm getting the correct end result, but I don't have the exact same steps as the validator, hence it's not correct

Fixed it. Had to move the print statement.

Lol.. Testcase 1 complete.. 2 error, 3 error, 4 error.. Wtf :(

Aaah

I'm an idiot

   static void Main(string[] args)
    {
        //1 3 9 8 2 7 5
        //int[] arr = { 5, 2, 1, 0, 8, 4, 3 };
        int[] arr = { 1, 3, 9, 8, 2, 7, 5 };
        QuickSort(arr);
        Console.ReadLine();
    }

Whoops :P

Hjorthenify

15:23

Yay

Nailed it

Almo

:D

user92578

Aight I've got geography stuff in control

user92578

I'll call it a day now

Hjorthenify

I have math due and not under control.. Too many coding challenges

Moses Aprico

how can be a similar image rendered soooo differently?

Blue

15:35

Ouch, that blur.

Moses Aprico

with different game engine

yeah idk why

anyone ever went through this in unity?

frustrating rly. been tweaking without any good result :(

Hjorthenify

Probably some AA gone wrong

Moses Aprico

AA? Ancient Apparatition?

haha jk

idk what AA is tbh

Hjorthenify

Anti aliasing

Moses Aprico

doesn't see any in unity though

where is it located?

Hjorthenify

15:38

Not sure

docs.unity3d.com/Manual/script-Antialiasing.html

Almo

there are a bunch of texture import settings in unity. there's also a "pixel perfect" button somewhere that might be invovled

Moses Aprico

@Almo I think I see pixel perfect option only from text

Almo

It might be on sprites as well somewhere. I can't remember

Moses Aprico

yeah cant find any

Almo

:( sorry I don't remember where I saw that

and I'm just heading out

Moses Aprico

15:49

yeah np

JackFrost

@MosesAprico just found this: 1) May be "format" parameter of texture is "Compressed". Try "truecolor" or other. 2) May be "texure type" parameter is "Texture". Try "GUI".

and this:
change the sprite Filter mode settings from Billenear to Point.

and this:I had the same problem. Try changing the 'Pixels Per Unit' property on the sprite. Changing mine from 100 to 96 made a huge difference in the sharpness of the sprite.

The number you change it to really depends on the distance of the camera from the sprite so it varies by situation.

are they any help?

not sure how outdated they are mind :S

Jon

@MosesAprico you fix that issue lol

pretty easy to fix something like that, just have to check your settings

Moses Aprico

@JackFrost 1) It is already TrueColor. 2) It's Sprite, since I got to slice it. 3)Did the Point also. Tried from 50-300 PPU. But still no good. Idk why..

@Jon Yeah, I thought so. But apparently not :(

Jon

Pretty sure it is either your gameobject size / your imported texture size / anti-aliasing

Tell me what your pixel to unit ratio is for that sprite

Also tell me what your scale x/y values are for that sprite's gameobject

Moses Aprico

@Jon PPU = 50, Scale 0.75 0.75 1

Jon

16:03

can you post a screenshot of the properties window of that texture?

another place to check for AA, is in your project quality settings

Unity defaults anti-aliasing to 2 times

you can either turn it off completely, or play with the settings

You also need to set your Texture to Point clamp

Moses Aprico

@Jon there u go

Jon

:D

pretty solid settings

does this happen in the editor? or just on android?

Moses Aprico

editor, game window, unity remote 4, installed apk

all 4 of them!!

Jon

very strange.

wanna post the actual image in here? I can try it

Moses Aprico

btw, what's the green check boxes in the quality setting?

sure a moment

Jon

16:11

never noticed the green check.. so not sure what that is.. now I want to know what that is

Moses Aprico

Jon

a green checkbox in a column denotes the level currently chosen for that platform

Moses Aprico

@Jon can't change the selection tho

Jon

yeah i noticed that oo

try deleting the asset, and re-importing

almost llooks like yours is using a mipmap

Hjorthenify

Dammit Jon. You beat me by a min

answers.unity3d.com/questions/237793/…

Jon

16:15

hmm, also, your green checks are indicating that you are set to the lowest possible quality setting

Hjorthenify

Mipmaps might blur it

Jon

Yeah, you could disable mipmaps to see if it helps

but i just started a new project

mipmaps on

your graphic, and that is what it looks like -- just changed it to Point Clamp

Moses Aprico

Asset > Reimport All is the same right?

Rather than deleting it?

Unchecked the mip maps, more blurred. ugh

Jon

no, its not the same actually

your sprite is a blend between the white and black kids from McKids on NES

JackFrost

Falls off chair laughing

Jon

16:21

haha, i'm right, right?

Moses Aprico

jajajaja

hmm tried to reimport

unchecked the mipmap

but still the same

BUT!

Jon

that is messed up man...

is this a brand new project?

Moses Aprico

when I zoomed in in the scene view, the sprite actually not blurred

is it happen because I put it too small?

Jon

ahhh, yeah

Moses Aprico

because the "BIG version" is not blurred

Jon

16:22

adjust your camera

you can't expect unity to do much when your gameobject is the size of a booger

Moses Aprico

hmm

Jon

did you upsample that image in your original preview?

like, the one you posted in here

Moses Aprico

so it's too small i see

Jon

Yeah, lol more than likely :P

Moses Aprico

idk what u meant by upsample

Jon

16:24

the picture, did you resize it?

to make it look bigger

JackFrost

@Jon yeah it is literally their lovechild

Moses Aprico

@JackFrost getting back to your chair i see

Jon

oh shit Pip is here, act normal

Kevin van der Velden

What is this normal you speak of?

Jon

i don't know anymore...

Moses Aprico

16:26

@Jon yea. scaled 0.75 each x/y

btw

bigger PPU means better quality right?

Jon

no

bigger texture size is better quality

PPU is just for calculations -- and affects physics engine as well

Moses Aprico

hmm

Pip

@Jon :D

Jon

adjusting your PPU can't magically make your texture any clearer -- you can simply adjust your camera size

it will do the same thing

You just want to ensure that your objects are not too small in terms of unit sizes -- if you are going to use colliders

colliders gets really bonky when they are small

Moses Aprico

yeah. tried about 1/2 smaller cam size

and it looks good

Jon

16:30

cool

originally we were troubleshooting thinking that was the original image size

that is why everyone was assuming AA

Moses Aprico

But, the character is covering up the screen!

Jon

perfect, he's the star role

Moses Aprico

LOL

Jon

lol, you should be able to adjust it to fit your needs

not sure why it is still sampling it though

since you turned off all anti aliasing

Moses Aprico

do you want the apk file? it's literally already playable as alpha version

Jon

16:33

not really

you got screenshots?

Moses Aprico

Jon

endless runner type game?

Moses Aprico

yeah

that's why i need it small

cutting the camera size down won't help (gameplaywise)

Jon

right

when you render it on android, it is blurry too though?

android typically renders a lot cleaner

Moses Aprico

what do you mean by render it on android? it's the screenshot from my android device tho

Jon

16:42

yeah, that is what i meant

Moses Aprico

btw fun fact, the image I use on libgdx is 32x32 (so it's half smaller, but produce better image)

idk if you wanna try it

Jon

i dunno man, the one I am trying looks fine

Moses Aprico

huh? is it about 1/5 of the screen on 9:16 android platform build mode?

Jon

Moses Aprico

wow

i think i'm going to try it in a new project instead

Jon

16:50

lol might be worth it

not sure what is wrong with yours

Moses Aprico

this is so messed up man

lol

Jon

17:01

yeah, if it is your first Unity Project, don't worry about it

it gets better, then it gets a lot worse

Then you make comprimises

Moses Aprico

yeah. this is my first unity project

btw

Jon

it is a good first project

are the levels completely procedural?

Moses Aprico

i don't know what you mean by procedural level

but it's an endless runner style

actually, I'm thinking to move away from pixel art to vector one

idk if that can eliminate irrelevant problem like this

Jon

how do you define the walls is what I am asking

2^5 possibilities

difficulty based on the distance of the transition

Moses Aprico

it's completely random. 1 Row is 1 Prefab, and I use InvokeRepeating to call it

with object pooling

each time an object is going to be activated, I randomize which stone to be set inactive (to create gap)

Jon

17:15

start immediately with 4 blocks / 1 door?

Moses Aprico

yeah

the range of doors is 3

Kevin van der Velden

My 10 year old cousin think's I'm really cool. He realized last weekend that I make games and I invited him (and his slightly older sister) to come and make a game some time

Moses Aprico

the current door and the next door

(max range i meant)

Kevin van der Velden

Might make a endless runner in unity, sounds reasonably easy

Jon

should be, just know how to do a repeating background

Moses Aprico

17:18

@Jon InvokeRepeating too with object pooling?

Jon

I use quads

translate it on the shader

Moses Aprico

i see. Btw, in below video, it seems using pixel art graphic too

but

why doesn't it blurred like I do? He seems doesn't do many configuration either

Unity 5 2D Platformer Tutorial - Part 1 - Setup, Animations

►

Jon

you tried starting a new project?

Moses Aprico

nope

just thinking, he use pixel art as well (or 2d generally)

but didn't do much configuration on the sprite

(well I learned unity 2d with this tutorial series as well)

Jon

17:40

BTW, you guys hear that Valve is ditching DX12

Everyone is going Vulkan

(which has full linux support)

the much popular slide :

Moses Aprico

when was that announcened?

Jon

today

it just makes sense, steambox runs on linux

their vive is coming out, they want to have a unified platform

Oh, and the new Unreal Tournament is out, and its free

And it looks amazing

Moses Aprico

18:03

btw

this bean man from unity tutorial is also blurred

problem is similar. the good thing is, good to know that the problem is not on the sprite (slicing some anxiety area lol)

Kevin van der Velden

Well, this is something I just wrote:

    typedef Class<SDL_Rect, ClassMethodWrapper<SDL_Rect, ClassWrapper<SDL_Rect> >, ClassWrapper<SDL_Rect> > Py_SDL_Rect;
    template < > template < > void Python::RegisterClass< SDL_Rect >::Finalize< Py_SDL_Rect >( PyObject* module, Py_SDL_Rect * rect )

That is a declaration for a single method

Moses Aprico

18:25

@Jon I can't believe I'm thinking about switching the concept of this game into 3d. I think it's much simpler graphical-wise after extensive reading about correcting 2d art in unity. Thoughts (for this noob haha)?

The problem is, ofc, the 3d artist required (duh)

Jon

that, and that you can't even get a 2d game to render properly :P

Moses Aprico

that hurt my pride. srsly

Hjorthenify

@KevinvanderVelden Throw it into a define

Moses Aprico

gotta try to make this work first then!! ugh

Hjorthenify

@MosesAprico How far have you come?

Kevin van der Velden

18:35

@Hjorthenify well, the calling bit is easy, that's a) auto generated, and b) RegisterClass< {{ class.name }} >::Finalize( module, &classDef )

It's just that classDef is... uhm, big

And they Finalize thing is only called from one spot so no one else needs to be bothered with it

Hjorthenify

Why are you complaining then? :P

Moses Aprico

@Hjorthenify tried configuring the camera orto size, make filter mode to point, uncheck all non-fantastic quality setting, turning AA off, unchecking mipmap, changing sprite format to truecolor, trying non-pixel art version of image, trying various Pixel Per Unit, idk what else to list

AND THE OUTCOME IS STILL BLURRED VISUAL ON UNITY REMOTE!!

Hjorthenify

Well.. How big is your project?

Is it only the sprite right now?

Moses Aprico

the backbone actually done. It's now visual problem, and after that, I'll implement unity ads, after that I can publish it to google play

Kevin van der Velden

@Hjorthenify because it's still horrid =p

Moses Aprico

18:38

The major problem is the sprite

Hjorthenify

Oh you're that far

Didn't realize :P

Moses Aprico

HOLY CRAP

BUILD TO APK VERSION, INSTALLED IT, AND IT DOESN'T BLURRED ANYMORE (WITH ANOTHER NON-PIXEL ART IMAGE)

Hjorthenify

What's the resolution on the non-pixel one?

Moses Aprico

888x459

Hjorthenify

It might be the much higher resolution

Moses Aprico

18:44

yes i know

but in unity remote, it's blurred still

Hjorthenify

What about in the editor?

Moses Aprico

@Hjorthenify not as crisp as the apk version

top : apk, bot : unity remote

Hjorthenify

But what about in-editor?

As inside of Unity. How does it look there?

Moses Aprico

not as crisp as the apk version

Hjorthenify

Got a screenshot?

Moses Aprico

18:52

if i can order it based on quality, from worst to best : unity remote - editor - apk

Hjorthenify

apk might be because of the smaller screen

Moses Aprico

Hjorthenify

Unity remove is actually only sending pictures from unity to the phone.

Moses Aprico

@Hjorthenify well, the device I use for unity remote 4 is the same device I installed the apk in

Hjorthenify

Yes. But its only sending pictures. I'm getting far worse quality using the remote as well.

Also I see your quality settings says half res at texture quality

Moses Aprico

18:55

well, it's cumbersome actually, to build to apk each time I wanna test it

No, it isn't

Full res at texture quality

Hjorthenify

Earlier picture said it wasn't

Moses Aprico

hmm

maybe i've changed it

(unconsiously?)

Hjorthenify

maybe

Moses Aprico

btw, it's already 2am here in Indonesia. Cya guys. See you around soon!

Jon

sleep is for babies

Hjorthenify

Sleep? Isn't that the luxury that non-programmers get?

Man I don't know what I want to do..

@MickLH are you sure? this is my first link: adb.org

Jon

have you talked to your doctor about suicide?

Hjorthenify

Work on my game? It's been a while..
Do more challenges? Can't be arsed..
