@OMGtechy @AttackingHobo dead ones too tounges out X eyes im telling you

youll want them

AttackingHobo

@Joe Yeah. I'm planning on it

AttackingHobo

01:08

@Joe @OMGtechy @SpartanDonut ^

@Almo I removed the smooth motion on the camera. The snap seems more clean

Almo

03:15

@AttackingHobo i don't see that in the publkished one yet, but I really like the interpolated camera

AttackingHobo

03:55

@Almo oh I thougth you didn't like it... lol

@Almo should it be quick or slower?

Almo

04:22

no i totally like the smooth camera

I thought the way it was was fine

MLM

I like the smooth camera better as well. I think it makes the game look less polished having the snapping.

AttackingHobo

05:59

Mutch95

08:12

I've done it now

I don't even understand what's happening

It's weird because it's like the shader is only affects items when they're in the camera view

@AttackingHobo clue?

Mutch95

08:52

I think smoothstep is causing me this trouble

AttackingHobo

09:11

user92578

Simple normal mapping makes simple tiles look so much better:

user92578

Mutch95

procedural?

user92578

@AttackingHobo Really cool

user92578

Nah, GIMP plugin

Mutch95

09:12

I meant hobo's

user92578

ah

Mutch95

cause I really want to walk around in it

AttackingHobo

@Tyyppi_77 thanks. and @Mutch95 kind of procedural

Mutch95

why is making gradient shaders so difficult

user92578

because unity

Mutch95

09:13

I have to interpolate between two values

but If I use smoothstep, the rendering only occurs when the z position is met.

I know why but I just want this to be a surface shader like this

AttackingHobo

@Mutch95 do you want to walk on it?

user92578

I don't see what you mean

Mutch95

@AttackingHobo on your procedural map, Yes Please!

@Tyyppi_77 see that image?

user92578

yeah

user92578

But I don't see what is the effect there you want

Mutch95

09:15

I want a shader which changes colours by gradient

it's seen quite well on the far right, the tv

this is what i've got

user92578

how it's darker at the top of the TV box than it is at the bottom?

Mutch95

quite ugly

user92578

is that the effect?

Mutch95

Yes that's what i want

user92578

Wouldn't a simple light just do the trick?

Mutch95

09:18

nooooo

It's like a gradient shader

user92578

because that just looks like a light for me

Mutch95

and it has the flat colour theme

AttackingHobo

@Mutch95 lighting is a gradient shader most of the time. use some lights it will look so much better

Mutch95

I use directional light

and my shader doesn't read point light .-.

is there a way to do this though so it add's a gradient to all surfaces?

@AttackingHobo is the map explorable?

AttackingHobo

kind of

let me see

Mutch95

09:30

can I try :D?

oh I'm excited

AttackingHobo

09:49

@Mutch95 its laggy im working on it

Mutch95

alright :p

I'm just looking at this cool GLSL shader sandbox

Complete acid trip

glslsandbox.com/e#21648.0

I guess this is a nice minor change to my shader

with the gradient displaying when the camera is close to an object

AttackingHobo

10:10

@Mutch95 pretentiousarts.com/spacedoutinthe7thdimention

@Tyyppi_77 ^

user92578

realllly cool

AttackingHobo

@Lokkij check that out ^

@Tyyppi_77 :)

Lokkij

Looks awesome

I like the shader

AttackingHobo

lol

Mutch95

that is cool!

is there a way to retrieve the lights pos or angle in CGPROGRAM?

:/

AttackingHobo

10:39

?

Lokkij

Holy shit that looks really cool

AttackingHobo

@Lokkij thanks

Lokkij

I like that view a lot less

AttackingHobo

@Lokkij how bout that

Lokkij

Hmm. It's better, but I like the first one best.

AttackingHobo

user92578

How would I go about rendering some basic geometric shapes line a box that only has outlines or a box filled with a color in OpenGL? A separate shader?

Anko

11:22

@AttackingHobo Reminds me of Gunkanjima.

I mean, the previous pictures.

user92578

aihgt I'm almost back to what I had with SDL

user92578

I need text rendering back and then I need to figure out why the performance is so crappy

Anko

@SpartanDonut If you've come up with anything even a slightly more detailed answer for that snapping-to-surfaces question I'd be happy to bounty-award that. (Just a reminder. There's 3 days left of it and the existing answer is boooriiinnggg. :D)

Lasse

11:38

Profiling, profiling, profiling.

@Tyyppi_77 Profiling is your best friend

user92578

12:43

My WTF moment of the day

user92578

like it makes no sense

Ali.S

@Anko @SpartanDonut how is that hard?

I mean, just think about it!

save a copy of mesh vertices cpu side

and when you have mesh you also do have the normals

Lasse

@Tyyppi_77 Github itself is not open source either

user92578

yeah

user92578

12:53

but an utility app like that definetely should be, at least when the app itself is lacking a dark theme...

user92578

every program needs a dark theme

Ali.S

you just need to adjust your physics engine so that for each object, gravity is exactly opposite direction of that normal vector

Jon

13:11

MinuteMaid is a really bad name for a company

Anko

@Ali.S I hadn't thought of anything like that. Maybe you should write an answer. :)

Ali.S

@Anko I'm writing it

Anko

Yey :D

user92578

what GL_RGB enum should I use for data that has 8 bits per pixel?

Jon

24 bit

RGBA8

well, if you want the alpha channel.. if not RGB8

user92578

13:14

I should probably recode all my text rendering as I'm currently just getting a black box...

Jon

either that, or fix it

lol

can you see my hat?

i don't see it

meh, hats are kinda weird

user92578

no i dont

Jon

i took it off

user92578

I have over 1500 draw calls a frame, no wonder it's so slow

Jon

yah.. batch that

you probably need to implement your own spritebatching

user92578

13:19

I wonder what would be a good place to implement that...

user92578

in the renderer? a separate class?

Jon

I'd look at where you are making the draw calls

and go as low level as you can

then implement it there, lol

user92578

Currently most of the draw calls are coming from the box renderer... that process doesn't even use any textures

user92578

maybe I'll just create a CLineBatcher, a CBoxBatcher and a CSpriteBatcher

Jon

are you using any sort of profiler?

user92578

13:23

I used NVIDIA Nsight for seeing what happens in one frame in terms of GPU calls

user92578

CPU profiling comes out clean

user92578

so some simple batching should solve my problems

Ali.S

@Anko done

Just setup a few new OSes, Linux was the only one that worked out of the box flawlessly on every machine and supported all the hardware ;)

But to be fair, microsoft did solve the issues with one of their programs after only like 10 minutes on the phone.

@AttackingHobo it just occured to me that you probably misunderstood me earlier, there is no good reason to use the standard naive FXAA / MLAA approach there, you already know everything you need while rendering the cubes, you can even do a 2 pass system with only the wireframe to reduce blending bandwidth if you can't make the dynamic background procedural

Jon

16:49

@AttackingHobo so gonna add an option for font selection - since you convinced me

old numbers are at the left -- new at the right

Jon

17:05

Jon

17:18

Which one is best between those 3 ?

Joe

17:41

I like second that will work on any color

Jon

dropping #1

gonna put 2 and 3 as options I think

since @AttackingHobo is really persistent about it

Almo

maybe you should ask a graphic designer

it's their job to figure these things out :)

TheMuffinCoder

17:56

Hey guys!

I have a yes or no question

Is Direct3D free to use? (like OpenGL is free to use)

Jon

pfft. @Almo

TheMuffinCoder

?

Jon

Almo

@Jon I'm serious

TheMuffinCoder

plz dont do lmgtfy.com/?q=is+direct3d+free+to+use

Almo

18:01

if the question is legibility, then graphic designers are all about that

Jon

I think i'm getting there @Almo

not interested in hiring some random

Almo

it's definitely improving

i don't mean hire

that was a StackExchange site

they will answer for free

post some of your options and ask what they think

maybe the question has already been answered

Jon

yeah I guess

I was thinking of putting black on lighter tiles, and white on darker tiles.

but i think white looks better

Attacking hobo prefers the black

So I was goin to add an option for black fonts -- and have it default to white

@TheMuffinCoder btw, your answer is yes

TheMuffinCoder

@Jon THANKS

i wasnt sure since different sources said otherwise

Jon

what sources?

TheMuffinCoder

18:10

yahoo....

Jon

there is no licensing required to sell directx products

you can write something , sell it, make hundreds, and keep it all

TheMuffinCoder

Thank you Jon so much

Jon

i live to give

so once I get this color version design done, i'm gonna have to upgrade the original to have a similar look and feel

oh shiiiiiiit

►

Almo

:D

Jon

my first review

its so awesome to watch some new play it, :D

she really liked it too, thats so cool

SpartanDonut

18:54

How did she get your game?

Jon

I found her on reddit

i've been asking around for people to review it

she doesn't have a massive number of followers, but she got a gameplay video totally legit experience, totally legit review on youtube for me

Love her for it.

Ali.S

19:13

@SpartanDonut did you understand/try my answer?

SpartanDonut

I have no clue how to do the copy verts approach

Ali.S

that's the problem?

SpartanDonut

well I have solved my problem

Ali.S

:D

SpartanDonut

the second part of your answer is similar to how I solved it (I solved it before you answered)

Ali.S

19:15

kk

then share your own answer

SpartanDonut

I gave you a vote - still going to write up my answer and I'll also be talking about camera and player movement a bit too

AttackingHobo

@Jon This actually works out well. Good contrast with a bright background.

Thick black outline on a bright color works fine john. As long as the silhouette is of the letters are dark against a bright background its easy to read.

AttackingHobo

20:35

@Mutch95 sup

Jon

20:50

@AttackingHobo the white one?

AttackingHobo

Yeah. I replied to that one didn't I?

Jon

i dunno

AttackingHobo

click the little reply arrow next to my comment

Jon

ah cool

didn't even know that was something

i also think it is the best one up to now

AttackingHobo

click the arrow next to a comment and you reply to that specific comment

Yeah it looks the best and is the most readable

the black on dark bg was weird

AttackingHobo

21:45

Lasse

21:57

eh

An unhandled exception of type 'System.ArgumentException' occurred in System.Drawing.dll

Additional information: Parameter is not valid.

var bmp = new Bitmap(files[i]);

files[i] = "Assets/Textures/sh3_n.jpg"

how this can not be valid

the previous filename in the array was valid

it was just "Assets/Textures/sh3.jpg"

also the documentation does not say that it would throw that exception: msdn.microsoft.com/en-us/library/0cbhe98f(v=vs.110).aspx

OMGtechy

ello folks

AttackingHobo

@OMGtechy sup

Lasse

hi

OMGtechy

how goes things?

AttackingHobo

OMGtechy

22:10

umm

ok then

AttackingHobo

lol

OMGtechy

Question, if you had the choice between no braces and braces (i.e. python style blocks vs C-like blocks), which would you choose and why?

AttackingHobo

braces for sure

@OMGtechy its more clear where things start and end

I can select start or end bracket and my IDE will highlight the opposite

if(a) {blah} else {asdfasdf};

one liner if else with braces. not the cleanest but its been done before

OMGtechy

I'd usually use the ternary operator for things like that, but I see your point. Reason I ask is because I'm considering dropping the no-braces thing in that language I'm mkaing

Lasse

braces are more clear code block than indentation

AttackingHobo

22:17

^

OMGtechy

That's subjective tbh, but it's good to know how you see it

AttackingHobo

@OMGtechy also sometimes I will do weird alignment things for the sake of readability

OMGtechy

Example?

AttackingHobo

I removed a few tabs in large nested logic chain so it could fit in my text editor window

with tab based stuff it would break it. but it was fine with the braces

OMGtechy

Surely you'd just be better off reducing tab size?

AttackingHobo

22:19

meh

I don't do that

OMGtechy

Still they're valid points

AttackingHobo

using tabs makes it very rigid for no good reason

I don't like the language restricting me in arbitrary ways

OMGtechy

Well, Python does it and I love it personally. I haven't found a time where I wished I could use braces. But then again, I need to see both sides of this

Lasse

at my workplace our strict coding conventions rule that tabs are two spaces, which makes the braces even more clear compared to indentation

OMGtechy

Wait what? Why would they restrict your tab sizes? It's a personal choice and has no effect on others

or do you mean indentation not tabs?

Lasse

22:25

some software does not like tab characters, so we convert them to spaces

OMGtechy

oh right, so you didn't mean tabs you meant indentation

Lasse

what did you think I ment with tabs? :P

OMGtechy

The editor display size must be set to two spaces :P

I was like whaaat

Lasse

lol

OMGtechy

anyway, some good points folks thanks

was watching a video by Douglas Crockford which had a few good points

prompted me to look at what I had so far again

AttackingHobo

22:31

@OMGtechy link?

OMGtechy

47 mins ago, by Lasse

also the documentation does not say that it would throw that exception: http://msdn.microsoft.com/en-us/library/0cbhe98f(v=vs.110).aspx

apparantly System.Drawing.Bitmap now throws wrong exception when the file is not found

why.jpg microsoft, why.jpg

T_T

OMGtechy

ahaha

Jon

that is art.

Lasse

I wish the file name of that was why.jpg

Saw this posted in the HTML/CSS room by cryptic: Vulnerability: update your Git clients

OMGtechy

23:00

Yeah Josh posted that here a while back, but thank you!

Jon

nice

MLM

ahh, cool. Should of been starred: chat.stackexchange.com/transcript/19?m=19154591#19154591

OMGtechy

Indeed. Good idea.

I'm surprised such an exploit hasn't come up before, it's quite simple.

AttackingHobo

@Almo GOT A NEW HIGHSCORE. 41

Its off the screen. hahaha.

OMGtechy

23:18

Hmm, is there any point to variadic functions when you have a unified type system?

AttackingHobo

@OMGtechy Average(numbers ...)

OMGtechy

@AttackingHobo vs. just passing an array?

AttackingHobo

yeah... its easier to just pass a bunch of vars

OMGtechy

Mmm

Jon

man coding is awesome

OMGtechy

23:21

it is, why are you pointing it out though?

Jon

why not?

OMGtechy

fair point aha

ok rephrased

what has prompted this sudden elation?

Jon

reality

so yesterday i got 3 sales

OMGtechy

awesome :D

Jon

which is like.. the lowest amount of sales I have gotten since release

no its horrible, lol

I figured my peak was done

OMGtechy

23:24

I'd just be happy I got sales for something I made

Jon

11 hours left for today, and i'm at 8 sales

my record is 9

so like.. :D:D:D:D:D

OMGtechy

:D :D :D

AttackingHobo

8======D

OMGtechy

Do you ever wonder who these people are? Like, what they do, if they have a family etc.

Jon

they are all over the world

germany, indonedia, united states, norway, australia, its crazy

i wonder if they play my game while they shit

3

if so, then i made it

MLM

23:26

I like it and play it everyday. I do not play any games on the toilet though

OMGtechy

ahahahah

Jon

if just one person I never met, played my game while they shat

Lasse

I play mobile games mostly on the toilet, because I don't really have time or interest to play them elsewhere

Jon

just knowing this, even if it is just a statistic, allows me to continue developing

I thrive on making games that help people drop a brick

its just what I enjoy .. ya know/

its an artform really

Lasse

yeah, we need people producing all these games playable on toilet

Jon

23:30

if the game lasts too long, you are immediately out of the poop loop

OMGtechy

this is the biggest revelation in game design known to man

Jon

if I can't finish taking a shit in 1 level, then you failed big time

first thing I do when testing anyways

Lasse

I can finish several games of jetpack joyride while taking a shit

a perfect game

Jon

golden game ratio

AttackingHobo

@Jon @Joe @Lasse @OMGtechy @Almo @hasherr @SpartanDonut @AidanMueller ^^^

Lasse

I don't like how the previous blocks fall in front of the current game, blocking the view

AttackingHobo

@Lasse lol

Lasse

but it's great otherwise (Y)

OMGtechy

@AttackingHobo can't see faces on black blocks

Lasse

oh right, no emoticons here

OMGtechy

23:53

or dark blocks

AttackingHobo

@OMGtechy racist

OMGtechy

aha
