HEY GUYS!

I have a "quick" question!

What aspect ratio do u guys usually use for games

16:9? 4:3?

I was originally using 640 by 480

snake5

16:9

1024x576

TheMuffinCoder

Thank you!

Icy Defiance

16:10 is (kind of) common too

TheMuffinCoder

I was about to ask u what resolution u usually used

AttackingHobo

@TheMuffinCoder depends what your target platform is

and what kind of game you are using

TheMuffinCoder

9:03 PM

2d platformer/scroller?

AttackingHobo

is that an answer or question?

TheMuffinCoder

A answer to ur question :D

snake5

both? :D

AttackingHobo

@snake5 I think you are right about the mapping being slightly off

snake5

heh

AttackingHobo

9:06 PM

zoomed in on the balls when they were not broken yet and the reflections were not touching like they should have been

They do update in realtime however

snake5

yeah

it's really obvious in this screenshot

I wonder how much time it takes to render those cubemaps though

AttackingHobo

idk. im getting like 160fps

snake5

maybe they're using some sort of cheap textured box for the background?

AttackingHobo

131 in that pic

no the bg is all real 3d

snake5

because the problem with these sorts of renderings is that there's lots of render target switching involved

AttackingHobo

9:09 PM

really high poly 3d too

snake5

I've heard that's not exactly fast with many GPUs

AttackingHobo

@Almo hey. I need some fast music with heavy bass, stat.

SpartanDonut

I think Lady Gaga is what you're looking for ;P

snake5

or the MGR soundtrack

youtube.com/watch?v=pz01CVHVM_0 this comes to mind

Lasse

They could be sphere maps too

snake5

9:17 PM

dual paraboloid maps, you mean?

or some kind of non-standard raytracing?

Lasse

Sphere mapping

In computer graphics, sphere mapping (or spherical environment mapping) is a type of reflection mapping that approximates reflective surfaces by considering the environment to be an infinitely far-away spherical wall. This environment is stored as a texture depicting what a mirrored sphere would look like if it were placed into the environment, using an orthographic projection (as opposed to one with perspective). This texture contains reflective data for the entire environment, except for the spot directly behind the sphere. (For one example of such an object, see Escher's drawing Hand wit...

snake5

you can't render a sphere map effectively with generic rasterization

Lasse

maybe they are gasp faking it

that's unheard of

snake5

faking it how?

cubemaps are easy to do and well-supported, even if a bit slow

so they're the obvious choice

dual paraboloid maps is the only way I've heard anyone ever come close to sphere mapping

it was heavily researched for point light shadow mapping, iirc

haven't ever seen it in practice, though

even Uncharted 3 used something else, it seemed

Almo

@AttackingHobo fast with heavy bass

just a sec

I don't know much high BPM stuff

when you say "fast" you mean like Jungle kind of fast?

AttackingHobo

9:23 PM

high energy or w/e

snake5

the problems with DPM are that there are noticeable seams and perspective distortion

Almo

let me look

►

once the kick comes in, that's fairly deep

►

might not qualify as "high energy" but it's not slow, and it has some super-deep bass in it

snake5

why does it seem that german electronic composers have a different sense of hearing than everyone else?

they can push all these high-pressure synths in and never give a damn about their overwhelming influence on the mix

Almo

and last one, also might not be high enough energy, but also deep bass, and decent tempo:

►

AttackingHobo

@Almo thanks. still listening to the first one. If you have any artist or album recomendations that would be cool too. I wanna build some playlists on google music

hasherr

9:29 PM

So I have a weird bug in my decode algorithm. it only decodes 1/3rd of the message exactly

Almo

As a starting point into the Deepchord stuff, try the album Liumin. Solid all the way through, pure analog.

snake5

@hasherr nothing weird there, sounds like a loop limit miscalculation

Almo

Deepchord almost always features thick atmospherics, medium tempos, and decent amounts of bass.

hasherr

That's exactly what it is, it's just tricky to find.

AttackingHobo

@Almo Deepchord Presents: Echospace?

hasherr

9:31 PM

Lot's of 3's going everywhere, things are tricky.

Almo

@AttackingHobo yeah that

it's Deepchord (Rod Modell) with one of his pals from Chicago.

Rod's from Detroit

snake5

@hasherr you could try to multiply the end result by 3 and check decoding for different message lengths, if it works - ship it

dunno about many algorithms that use the number 3 though

base64 perhaps

AttackingHobo

@hasherr easy fix. just copy encoded message 3 times and decode that

snake5

may not work if integer division is involved

hasherr

It's a bit more complicated than that, guys.

I'm trying to decode an image out of another one.

snake5

9:34 PM

rgb to grayscale or what?

hasherr

No

Steganography

Steganography (US /ˌstɛ.ɡʌnˈɔː.ɡrʌ.fi/, UK /ˌstɛɡ.ənˈɒɡ.rə.fi/) is the art or practice of concealing a message, image, or file within another message, image, or file. The word steganography combines the Ancient Greek words steganos (στεγανός), meaning "covered, concealed, or protected", and graphein (γράφειν) meaning "writing". The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography, disguised as a book on magic. Generally, the hidden messages will appear to be (or be part of) something else: images, articles, shopping...

AttackingHobo

yeah, was gonna say it sounds like Steganography

snake5

image -> image or is there another reference image involved?

hmm, bit chopping

funny stuff

Aidan Mueller

10:01 PM

I've been hearing that sitting is like really unhealthy.

...

Should I stand now?

I'm kneeling right now.

But that's probably bad for the knees.

Chris

lots of things are unhealthy

Aidan Mueller

@Chris Like PHP?

Chris

has its pros and cons :p

Aidan Mueller

Pros: It's not as bad as Lisp.

Or scheme for that matter.

Most languages you actually start programming even if you don't know them just by looking at them for a bit.

Not with scheme.

Why did gimp base most of their scripts on scheme.

I wish that they would switch some of it to python.

AttackingHobo

FUCK PROGRAMS THAT STEAL FOCUS

7

Aidan Mueller

10:05 PM

Since there already is python support.

Focus of any kind can be annoying.

I think I may decide to switch my window manager's focus mode.

Maybe to focus follows mouse.

I don't know, what I use now can be a bit annoying.

Almo

@AttackingHobo have a star. i hate that shit

AttackingHobo

@Almo Monodevelop did it 3 times while starting up!

Starting up. I click chrome to type

Almo

:(

AttackingHobo

bam it steals focus

I click back to chrome and second later stolen focus, <repeat that

Almo

yeah

Icy Defiance

10:12 PM

@AidanMueller focus follows mouse sounds more annoying. click on textbox in one window, move mouse away so it's not blocking what you type, focus goes to new window where you accidentally hit the keyboard shortcut to send a rage email to your boss and you get fired and become homeless

Almo

like I don't know how to find the window in the dock/taskbar

XWindows used to use mouse-location focus

I shouldn't need a third-party plugin to do this:

BlueBug

made sheep animation lol

Chris

awesome

BlueBug

I made it but I think he looks really cute.

CUTTTT333!

TY Chris!

Icy Defiance

10:27 PM

nervous sheep doesn't want anyone to see him eat

then you just post him on the internet. what a jerk.

BlueBug

he's so afraid of the wolf that wants his meat. I would have given him privacy but he was so cut3333 to resist to not share.

Aidan Mueller

►

BlueBug

wooha

Dat is cool!

Aidan Mueller

Wrong one.

►

Imagine the things that you could do with this with video games.

BlueBug

and DAT is sooo cool.

so the projection changes based on the position of the camera. I see.

Aidan Mueller

10:33 PM

►

Part two is cooler.

snake5

no postproduction, lots of preproduction

Aidan Mueller

LOL

snake5

looks great, except for all the people moving things

Aidan Mueller

Imagine an entire film like this.

snake5

would be completely fine for a theater experience, though

I wouldn't want to have such films, this deserves to be a live performance

Aidan Mueller

10:36 PM

But imagine the game applications.

snake5

films are for the impossible things

Aidan Mueller

Yeah.

snake5

game applications?

Aidan Mueller

Real life health bars.

I don't know.

I'd like to experiment with this.

snake5

not much to experiment here

it's a set with a projector and specifically tuned content

BlueBug

10:37 PM

we had something like this in our school

snake5

if you want to project healthbars on walls, that's doable

Aidan Mueller

@snake5 It's projection mapping.

snake5

don't think there's much more to do though

BlueBug

We didn't have the projection to follow the player but we have simple surrounding 360 degree monitor thinging.

Aidan Mueller

I just think you could use this for immersion.

Of course, it wouldn't immerse you like an oculus, but it would still be cool.

snake5

10:38 PM

works only from one point of view and requires a special room

Aidan Mueller

Not always.

snake5

I mean, fine for some amusement park

definitely not for home entertainment

Aidan Mueller

That was done at home.

►

No studio.

And it works from all perspectives.

snake5

doesn't matter where if they build content for it exclusively

that's the problem

content fits one specific setup

any deviations will just mess everything up

Aidan Mueller

Oh of course you wouldn't do it exclusively.

I was just thinking as an option or something.

@snake5 Projection mapping software is configurable.

It's not like stuff has to be in a certain place.

snake5

10:41 PM

sure it is, but the room may not be

Aidan Mueller

It's 2D clips projected onto 3D objects.

snake5

any extra columns, holes, decorations, no fitting place for a projection device

SpartanDonut

How do I find the vector that would describe the the relationship between one point/vector and another

Trying to move an object from vector A to vector B

snake5

also, it needs white walls

not common in homes

Aidan Mueller

No. It just needs white objects.

Like boxes and stuff.

snake5

10:42 PM

if you're willing to redecorate on and off occasionally

Aidan Mueller

I am talking about using this in combination with a TV.

snake5

people are generally lazy, if they can't put something together in less than a minute, most won't go for it

and this requires quite a lot of work to set things up the right way

Aidan Mueller

I am not saying that this would be something that you would actually put into a real game. Just something to mess around with.

AttackingHobo

@SpartanDonut add the vectors and normalize

Aidan Mueller

Just for the fun of it.

AttackingHobo

10:43 PM

answers.unity3d.com/questions/437111/…

SpartanDonut

Thank you sir

snake5

well, for fun, buy a projector and hang it on the ceiling

render game to two outputs

one for each screen

Aidan Mueller

And do google earth skydiving?

snake5

if you wish

the shadow would get in the way though

might need more than one projector

that's extremely expensive too

at least where I live

Aidan Mueller

Not if you are close enough to the projector (and off to the side).

►

snake5

10:46 PM

so you're going to need to construct a way to stay above ground

Aidan Mueller

Yeah.

snake5

easier said than done in a usual home/apartment

quite easy in a bigger room though

anyway...

I've got a game here

I'd like to hear some thoughts about it

See ya.

Wait, are you leaving?

Or no.

You made it sound like you were leaving.

snake5

10:50 PM

not just yet :)

Aidan Mueller

@snake5 The only options it gives me is 144p, and 720p. What's with that?

snake5

@AidanMueller for the video? that's odd, I get all the usual ones

Aidan Mueller

Hmm.

I'll try to refresh.

Oh.

It also has 480.

I think that one just appeared.

But I may be able to play 480.

I used to do 360.

But I got an upgrade for my internet.

Chris

@snake5 Objectives look cool

Aidan Mueller

Now I get ~3.75 Mbps.

Chris

10:52 PM

At first I thought it was supposed to be underwater, like you're controlling a submarine

Aidan Mueller

Ok, now I refreshed and I have them all. I think they just looked grayed out or something.

@Chris Same.

@snake5 Cool title screen.

snake5

@Chris heh, I guess that's because of how the player-controlled device looks and moves

Chris

hehe yeah

Aidan Mueller

@snake5 Really cool. I liked it.

Chris

reminded me a bit too of Perfect Dark, sending your little spy camera around to do things

Aidan Mueller

10:57 PM

:P

snake5

thanks for the positive response :)

btw, there's a download link for a Windows version in the description

(in case somebody didn't notice)

Aidan Mueller

Cool.

@snake5 What libraries and what not did you use?

Icy Defiance

aight, I'm trying to stream a league game, see if I can maintain 60 fps and not lag to shit. if anyone wants to watch, here's a link: twitch.tv/icydefiance

Aidan Mueller

@snake5 BTW, I wold change the model of the vehicle. It looks like a submarine.

snake5

@AidanMueller a lot of my own stuff (SGScript and the related addons) and some external libraries like SDL2, Bullet, OpenAL

Aidan Mueller

10:59 PM

Anything that advanced wouldn't be using propellers.

@snake5 So you used cross platform libraries then?

snake5

@AidanMueller what would it be using?

Aidan Mueller

Because if you did, then I would expect it to work in wine.

snake5

@AidanMueller yeah, though some of them aren't fully ported yet

I've heard it works in Wine on OSX

Aidan Mueller

@snake5 I don't know. Some sort of glowing thing.

snake5

haven't tested myself though

@AidanMueller I thought of fire but that would leave marks on the environment, something a stealth-capable drone-like device shouldn't do

Aidan Mueller

11:01 PM

I actually haven't installed wine yet.

I've gotten by without using any windows apps until now.

snake5

besides, lots of drones use propellers so I just thought it made sense to stick with that

Aidan Mueller

Which was my main worry when I first switched to linux.

@snake5 What I'm saying is that it's floating.

So you would expect it to use rockets or something.

snake5

rockets are a bit too heavy for this kind of work

would look good, though

I had an idea that I could implement part switching points

Aidan Mueller

@snake5 The main problem is that it looks like a submarine. Maybe if you would make it look like some sort of super cool looking turbine, it would look more appropriate.

snake5

like places where you could go and swap parts of the device for different ones

Aidan Mueller

11:03 PM

That sounds cool.

Like upgrades?

snake5

upgrades too

but also just different things

like machine guns vs lasers vs flamethrowers

for the weapon attachment

Aidan Mueller

@snake5 The graphics remind me of quake-era games.

snake5

fire-based vs propeller-based for elevation/turning systems

@AidanMueller as for the submarine look, I guess the shape adds most to that, and the shape is really something temporary I quickly made in Blender

@AidanMueller well, that's something; for a more complete version I would probably go for a lot more decorations than that

so that there wouldn't be just walls everywhere

which is why I guess it looks a lot like games from that era

the tech at the time was really favoring plain walls and floors over everything else

anyway..

Aidan Mueller

@snake5 I'm not saying that it's a bad thing.

snake5

I guess I have to go get some sleep now

Aidan Mueller

11:11 PM

I'm just saying, it has an old style for some reason.

snake5

yeah, I understand

though that reason was more lack of resources than anything else

Aidan Mueller

Plus the tools back then.

I think it was partially because you had to do a lot more work.

No unity or anything like that.

snake5

I still have to do a lot of work, that hasn't really gone away

the game wouldn't look even near the way it did if I used unity

had to use a laptop for the presentation, only had dynamic lighting implemented, so I had to write a software occlusion culling add-on to get it near 60 fps on that laptop on 800x480 or some similar resolution

the free version of unity doesn't support occlusion culling afaik

I could use lightmaps there, though
