@Jon same

oh wow minecraft actually made my PC noisy

Jon

skyrim made my video card hardware issue apparent

which is why i bought a new video card

Alex M.

my gpu was also pretty noisy back in the day

Jon

bad fan

didn't wanna fix

Alex M.

but the truth is, the HDD was the noisiest

after switching to an SSD in pretty much all situations I can barely hear my PC

Jon

00:06

yeah.. SSD are awesome

Necromonster! Necromonster is a 2D, topdown RPG. You can read all about the story and game mechanic in Readme of the Github Repo! Language: Python (2.7) Required Libs: Pygame, NumPy(for path-finding) If you don't have python, here is the 100th commit build. It is 15 commits behind and a...

there we go

Jon

Necromonicon

Christian Careaga

haha what does that mean!?

Jon

you ever watch evil dead?

Christian Careaga

haha nope

Jon

00:07

ah, well then.

necronomicon was the book of the dead

when you read from it, the dead would come to life

Christian Careaga

that's scary

Jon

it was one of the best low budget horror movies ever made

spawned higher budget sequels

army of darkness

imdb.com/title/tt0106308

pretty awesome movie, ehehehe

A man is accidentally transported to 1300 A.D., where he must battle an army of the dead and retrieve the Necronomicon so he can return home.

original: imdb.com/title/tt0083907/?ref_=fn_al_tt_2

it is the movie where the lead actor cuts up his girlfriend with a chainsaw

Alex M.

finished the floor, time to work on the main building

Jon

then cuts off his hand, and replaces it with a chansaw

carries a shotgun in his right hand,... and has a replaced chainsaw hand on his left

so when he goes back in time, he calls it his boom boom stick

watch it.

@AlexM.

Alex M.

LOL

main building goes there, the rest will be gardens and ponds

Almo

anyone following Prison Architect?

sounds like an accessible version of Dwarf Fortress.

classy.

@Grey You are working on Malware Tyc. with Pip right?

Grey

yeashir

Christian Careaga

How's it going

Grey

SWELL

Christian Careaga

you guys got 8 upvotes on the projects page thing nice!

Grey

01:03

meh

I wish we had IN GAME SCREENSHOTS :(

Christian Careaga

haha it's not far along enough

I posted Necro!

Grey

upboating

Christian Careaga

Haha thanks!

Grey

UP_BOATED

Christian Careaga

you didnt have to!

Grey

01:13

i upboat everything

Christian Careaga

much apreciated!

Grey

@ChristianCareaga np man. It looks good!

Christian Careaga

Thanks, I'm excited to see your guy's game develop!

Alex M.

01:26

dat english

I'm going to make a 1:1 clone of dead or alive

and call it dead or die

Christian Careaga

Are you talking about my english ahha @AlexM.

Alex M.

yes, totally about your english

just ignore the picture that has broken english in it

I wasn't talking about it

how can the japanese be so good at so many things

yet suck so bad at speaking clean english

it's like they're doing it on purpose

Icy Defiance

dude, everyone is bad at speaking english

except some of the english themselves, maybe. but even there you get the cockney accent.

Christian Careaga

I suck at English and I'm American

Alex M.

@IcyDefiance c'mon you got what I meant

Icy Defiance

01:37

I tried very hard not to

Alex M.

►

depending on how true this is, they sort of are doing it on purpose

not sure how much bad english textbooks translate to bad english skills

never gave a shit about school LOL

the thing is, broken english is everywhere in their media

especially in games and anime

so I guess the average guy sees it and thinks it's correct

@IcyDefiance that's too bad

how can you discuss a matter if you try hard not to understand what others say?

anyway I feel like falling asleep lol

cya tomorrow

MickLH

peace

Christian Careaga

@IcyDefiance Your project looks pretty cool!

Battery It's a game I just work on occasionally. There used to be page where I've posted project updates (and some of the algorithms) occasionally. But it's been a long time since my last update. It's basically a 2.5D top-down chasing game, in which you, player as circle-shaped robot should ru...

@BlueBug so did you just woke up? or are you going to bed?

BlueBug

I just woke up o_o went bed at around 1:00AM but somehow my body refuses to sleep

Ali.S

08:02

@AlexM. I just missed the game jam :( and I was going to participate this time :(

joapet99

HAHAHA

Ali.S

why didn't you pinned the notification sooner?

joapet99

@BlueBug aren't you tired

BlueBug

#joapet99 I was. I even went for a mile run before I go to bed. but I feel like since I hadn't done much programming today, my mind is yet to be tired but my body only. So I guess that's why I woke up early

Christian Careaga

@Ali.S Nice project! I posted mine too!

Ali.S

08:06

@ChristianCareaga tnx :D

I'm reading that readme file of yours...

Christian Careaga

Yeah, I didn't want to post it on the actual posting because all of it is in the ReadMe :P

Ali.S

It actually looks very cool, keep working on that.

Christian Careaga

Thank you! We are both 15 so we kinda slowed down during school, but we are full-speed ahead now!

Ali.S

I'm 22, and I've got some other projects to work on, that's why my game's development is kinda ultra slow. But with your support I'm pretty sure I'll speed it up a little bit ;)

Christian Careaga

Yeah! just gotta get motivated! everyone as there own speed! haha

joapet99

08:15

youre in the minor gamedev league right

Christian Careaga

Yeah I'm part of it on bitbucket I think!

@joapet99

joapet99

have you made some commits

Christian Careaga

Nope, I just told Pip i'd help out if needed bc i'm decent with pygame

SpicyWeenie

09:04

@KevinvanderVelden I'm having problems getting my earth model to display on the screen

joapet99

so sad

SpicyWeenie

yes it is

joapet99

hey @Leathe

Leathe

hi

joapet99

@Leathe some projects going on?

Kevin van der Velden

09:08

@SpicyWeenie what's the problem?

SpicyWeenie

@KevinvanderVelden the model is loaded into memory, but not displaying

Kevin van der Velden

How are you trying to render it?

SpicyWeenie

through a shader

Kevin van der Velden

Gonna need more info than that :)

SpicyWeenie

It's kinda hard to explain. The program registers that the model is read with a texture (*dae), but when it comes to letting OpenGL do its magic to display it, I believe the problem I'm having letting the program know exact where to show it

joapet99

09:16

h-h

0.o.0.o

Leathe

@joapet99 not really

Kevin van der Velden

09:35

@SpicyWeenie did you verify that the model data is loaded properly? (i.e. the buffers are filled with numbers that make sense) Did you test the rendering with a simple cube build from code (i.e. without assimp, to just test the opengl bit)

SpicyWeenie

@KevinvanderVelden I think that's where my problem is. all my IDs except for my shaders and shader program IDs are 0's.

Kevin van der Velden

Seems like that could be it, first step of debugging: make the problem smaller =p

SpicyWeenie

yay! I'm gonna see where I messed up

Kevin van der Velden

And then you're gonna probably kick yourself over one tiny mistake, that's usually how it is :)

Q: Making C# mandelbrot drawing more efficient

First of all, I am aware that this question really sounds as if I didn't search, but I did, a lot. I wrote a small Mandelbrot drawing code for C#, it's basically a windows form with a PictureBox on which I draw the Mandelbrot set. My problem is, is that it's pretty slow. Without a deep zoom it ...

GTA V coming to Xbox One, PS4 and PC in June According to German Retailer manager

Kevin van der Velden

Huh, I will continue to ignore it at that time then

William 'MindWorX' Mariager

I still chuckle at people thinking it'll stay console exclusive.

Jon

Dude, this came from a German Retailer manager!

Its coming for PC eventually... just don't know when.

And next gen consoles.

they would be retarded to not release to xbone and ps4

unless .. i mean.. unless they don't like money

Alex M.

yay, wrote an editor extension for unity to make my life easier

I wish Orthello used generic collections instead of arrays in this case

I would have been able to avoid Array.Resize<T> calls

Jon

You should make a puzzle othello game

Turn all pieces over in 3 moves

Blam... next blockbuster puzzle game

Alex M.

11:09

I don't know how othello works

Jon

what is Orthello?

I thought it was Othello

lol

Alex M.

a 2D framework for Unity

Jon

ah... looks like you got replaced by 4.3

Alex M.

I can't switch to 4.3

I've been doing Orthello for the past 6 months and projects need to be completed quickly

Jon

Well, I mean.. Unity added sprites, and 2d collisions in 4.3

Alex M.

11:12

so I can't take the time to learn and experiment with 4.3

the existing libs I wrote to help with stuff including resolution independence would also have to be adapted to 4.3

Jon

Your animation module sounds awesome

Alex M.

so yeah I'd probably have to take a month just to experiment with 4.3 and transfer things over

Jon

But yeah, a lot of the functionality you provide was added in 4.3

So that sucks for you

You would have to strip out a lot of stuff from your engine

Alex M.

I know :(

the deal was I was going to work with Corona SDK until Unity released 4.3

but in the end, no Corona, only 4.2 w/ Orthello

Jon

at this point, better off waiting for unity 5

Alex M.

11:15

yup

just to be clear

I didn't develop Orthello

you sounded as if you got that impression :P

Jon

Yes.

Ok, so Orthello is the framework for the company you work for

?

Alex M.

orthello is a 3rd party lib we bought to get 2D stuff done quicker

Jon

ah ok

so i am gonna start working on a dungeon gen

not entirely sure how I'm gonna write it yet.

William 'MindWorX' Mariager

Can't let go of the 2D procedural generation :P

Jon

Thats the point

Next will be structures

I was debating putting tree/foliage.. but I think I might want to make it look more industrial... not sure yet

Writing a 2D city generator could be fun :)

William 'MindWorX' Mariager

11:28

Lots of industrial sandbox games lately

What's wrong with fantasy? :P

Jon

Lots of fantasy games, lol... Also, this isn't really a "game"

It has no direction

William 'MindWorX' Mariager

My Legeria theme was going to be magic/steam-punk.

Jon

My idea at the moment is to have a industrial oil drilling game

setup mine fields, oil processing plants, etc.

William 'MindWorX' Mariager

Did you ever get the lighting engine to work properly? Or did you find another solution

Jon

oh yeah, I ended up doing something different.. hold on

so caves that are not discovered are hidden

I'll most likely animate the cave appearing at some point

have the light propogate slower or something

William 'MindWorX' Mariager

11:32

Ah

Well, my system shouldn't reveal hidden caves either.

Jon

Yeah... main difference is that the light is calculated based on any edge

instead of just the outer edges

so you don't have to use point lights.

William 'MindWorX' Mariager

I'm not sure I understand

Mine wasn't point lights either :P

Jon

Your caves were completely lit?

William 'MindWorX' Mariager

They were?

Jon

It was a question

William 'MindWorX' Mariager

11:33

Well, no they weren't.

But could be with light sources.

Jon

Right.

William 'MindWorX' Mariager

But the light sources weren't point lights in the normal sense.

Jon

Originally I had the same concept, and you'd need some sort of light source to go deeper

William 'MindWorX' Mariager

The only reason my system did that was because it was configured to do so based on the background layer.

Jon

I reworked it, to have the above.. where you don't need a light source to go deeper... I'm also playing around with the idea of making it darker as you descend really deep

William 'MindWorX' Mariager

11:35

If you made all open blocks emit light, it'll work just like yours :)

Jon

And have a light aura around the player

Yeah, essentially... the main issue is properly hiding caves

You have to fake the gradient

otherwise you see the caves

So I have a flag that draws the caves as standard tiles until they are discovered

William 'MindWorX' Mariager

Ah

It looks cool though. :P

Jon

I think it makes me want to dig around to find caves

William 'MindWorX' Mariager

You should add RGB though, makes the scene more vibrant. :)

Jon

yeah.. how do i do that?

William 'MindWorX' Mariager

11:38

Well, I just treat each channel separately. Not sure how you should do it.

Jon

ah.. I have it strictly grayscale..

however I set the channels separately for each pixel in the shadow map

They are just locked together...

new Color(k,k,k)

William 'MindWorX' Mariager

Should be an easy fix then. :)

I really need to learn how shaders works properly and how to perform multiple passes efficiently.

Jon

I run mine in one pass

I set a color value to each tile.. then draw a render target at 1x1 scale of the world, each pixel representing the color set on each block

William 'MindWorX' Mariager

Is it a shader as well?

Jon

Yeah, then I run the rendertarget through a shader

single pass

William 'MindWorX' Mariager

11:43

Interesting.

How do you spread the light multiple tiles in one pass?

Jon

I stretch out the image, it creates a natural gradient immediately

Then I run it through a Multiply shader

William 'MindWorX' Mariager

Ah, so you just rely on what little it does.

I thought you still had a resistance per block as before :)

Jon

that is calculated at the cpu level

when a chunk is loaded, the weights are calculated once

William 'MindWorX' Mariager

Right

Jon

then again when blocks are destroyed

William 'MindWorX' Mariager

11:45

That's why I need multipass for my shader :)

Jon

You continually load the weights?

Greatly improve the speed of your algorithm if you just pre-calculated those values

Those are the new weight calcs... which is essentially "Distance To Edge"

anything with a 10 is black, and is culled

BlueBug

TIL Unity does not link prefab inside another prefab in Asset folder; prefab A in prefab B does not receive change made to prefab A in asset folder

the first one maybe

Jon

Alex M.

y u do this

Leathe

bye bye XP

Alex M.

leathe pls

Leathe

omg pls

William 'MindWorX' Mariager

12:48

@Jon Depends on the world size :)

Jon

Ah, see my world is generated on the fly.

William 'MindWorX' Mariager

I recalculate it as needed, based on movement and new lights.

I think we aren't in agreement on what precalculated is :P

Also, maybe I'm missing what weights mean.

I just update the light layer and then use it as a base for floodfill. Works perfectly, only suffering from my poor multipass method. :)

Jon

Yeah.

Does your world load chunks on the fly? or you generate a pre-defined world size?

William 'MindWorX' Mariager

I've had a mix of both, but I've actually ended up with predefined world sizes, because in a game where there are multiple dimensions, infinite world sizes become silly.

Jon

Yeah.. infinite world sizes are generally silly

But they add a lot of complexity as wel

which is fun

Hey there!

Jon

user92578

For some weird reason it takes like 2 minutes for task manager to open...

user92578

and thats so nice when I really need it

Alex M.

real men don't use task manager

they sell the PC

show that bitch you don't need her

user92578

It might be my hard-drive, it's constantly running at 100%

user92578

13:13

thought I can't see why that'd affect the loading of task manager

Jon

heh.. ever heard of swap space?

user92578

nope

Jon

sometimes ram gets unloaded onto HD

if you have a application minimized for a while for example.. the memory will get de-allocated to HD

user92578

Steam is using HD 0.7Mt/s, which translates to 99%

Jon

then if you click on it again, sometimes you will see it takes a while to pop back up.. that is because the data is being reloaded into ram

user92578

13:15

okay

Jon

hard drives are a pretty huge bottleneck

Alex M.

@Tyyppi_77 you're not fooling anyone

you're downloading porn

stop downloading porn you weirdo

Jon

Porn... you pervert.

Alex M.

stop staring at me like that

user92578

BTW I'm doing something that I haven't done in ages... listening to music from Windows Media PLayer :D

Alex M.

so I'll just add some css rules to autohide images lol

Jon

that's safe for work

I have girls working here that wear less than that

user92578

nice workplace

Jon

its a stripclub

user92578

oh cool, you a stripper too?

Jon

naw, i just freelance from here

Kevin van der Velden

@Jon as a stripper?

Alex M.

freelance stripper

Kevin van der Velden

Exactly, I doubt they're usually contracted =p

Jon

I'll give you 1 guess

Alex M.

the gd.se nerds and the stripper salute you

Multiple dispatch examples
In a language with multiple dispatch, such as Common Lisp, it might look more like this:

 (defmethod collide-with ((x asteroid) (y asteroid))
   ;; deal with asteroid hitting asteroid
   )
 (defmethod collide-with ((x asteroid) (y spaceship))
   ;; deal with asteroid hitting spaceship
   )
 (defmethod collide-with ((x spaceship) (y asteroid))
   ;; deal with spaceship hitting asteroid
   )
 (defmethod collide-with ((x spaceship) (y spaceship))
