@Jon Thanks for that article though it seems interesting

user92578

minecraft.gamepedia.com/NBT_Format#Software

Hippalectryon

@Tyyppi_77 Those only allow me to edit/view the NBT

I can't use that in a program

user92578

see if some of those are open sourced and check out how they do it

user92578

also check out PyMCLevel, it handles the same stuff as you need to

user92578

that is definetely os

Hippalectryon

12:02 PM

Ok

Jon

reverse engineering for fun is always cool in my book

Hippalectryon

:-)

Jon

do you know what is one of the biggest sucks about vb.net?

no multi-line comment blocks

Blue

Just use this:

#if false

#endif

Jon

yeah but

that is just ugly

Blue

12:06 PM

meh

Jon

better off using your IDE and click the comment button

Blue

Ctrl K Ctrl C

Jon

yeah I know about the two hit CTRL

just as inconvenient as a click in the toolbar, lol

Blue

Not really.

If you're looking for something more convenient than keyboard shortcuts then you're expecting a bit much :P

Jon

voice commands

"Computer, comment out the code i'm thinking about"

Blue

12:09 PM

Good luck there.

Jon

i remember voice dictation became this huge thing in the 90s

but it was shit

you had to train it, and it still didn't work

user92578

do you guys use NSight?

user92578

it's giving me this in a log file: glTexParameterf (Zero texture object not supported -- encountered on target of GL_TEXTURE_2D)

Jon

sounds like a null texture is trying to be accessed

user92578

not that that is the only problem... :D

user92578

12:22 PM

Jon

ouf

looks like a closeup of a smurf

user92578

moved to VAO stuff from the glVertex stuff

user92578

so I kinda expected this to happen, as I was pretty much programming like "I have no idea what I'm doing" yesterday

Jon

gotta start somewhere

i'm programming web services for a project i never worked on

here guys, use my webservices, lol

its the new way now :)

they used to be passing XML to our webservices -- so now its gonna be objects

the old service, parses out XML can you believe that? lol

if they change anything in the XML it breaks the webservice

Think about this.

user92578

glTexParameterf (Zero texture object not supported -- encountered on target of GL_TEXTURE_2D)
                                                   glTexEnvf

user92578

12:31 PM

that's the complete Nsight log

Jon

might be an nsight bug

see here: devtalk.nvidia.com/default/topic/547318/…

user92578

was actually my bug, i didnt bind the texture first

Jon

Do not use GL_TEXTURE_2D glTexParameteri/glTexParameterf with multisample textures

ah, ok, cool

user92578

now to the real problem... why is the rendering so weird

Jon

almost looks like the viewport is zoomed

user92578

12:35 PM

I need to open my laptop so that I can get my two main screens for code and then the laptop for the chat

user92578

too.... many... files...

user92578

i need a third screen.... but there's no room on my desk

Jon

Ideally, I'd hook up a 46inch screen above my two 23 inch monitors

user92578

the laptop is kinda like a third screen for me as I have my mouse and keyboard events sent to it

user92578

:D

Jon

12:37 PM

lol j/k

user92578

I can't find a GLSL syntax highlighter thingy for VS..?

Jon

did you install nsight for VS?

user92578

yeah

user92578

now visual studio thinks that my .fs (FragmentShader) file is a Visual F# file

Ali.S

@Tyyppi_77 from now on, use .frag instead of .fs

Jon

12:41 PM

gonna add a frag counter to my puzzle game.

it will always be 0

drive people crazy

Writing a Serializer, la la la

holy shit its still early, i need to slow down

almost blew right through this work

user92578

feeling pretty bad-ass

user92578

Jon

LOL, looks exactly like my setup right now

user92578

pic or it doesn't

SpartanDonut

:D

Jon

12:55 PM

user92578

but this NSight, like, "let's do an OpenGL debug thingy!" - "Yeah totally, but let's not put any shader syntax things in it!"

Jon

i'm messy

user92578

screens connected to the laptop?

SpartanDonut

@Ali.S it's a derogatory term that I really just don't like hearing

Jon

no.. screen connected to another dev box

user92578

12:57 PM

ah, me too. My laptop only has firefox and ms office tough, so not a dev laptop

user92578

and it has a 13'' screen so it's like really small

Jon

do you like my ghetto mouse pad?

SpartanDonut

user92578

I can't see it very well

SpartanDonut

Me before my third monitor (bottom right is a wacom tablet)

Jon

12:58 PM

lol @SpartanDonut

user92578

that's really cool @SpartanDonut

Jon

i have a shit bamboo

user92578

I think I might get myself one too

Jon

Yeah.. i want a rift first

so many things I need to buy, lol

user92578

:D

user92578

1:01 PM

A bug in VS: if a VS window is inactive, but still visible, you get hover effects on menus, but you can't activate the menus before you click in the code editor thus giving the window focus

user92578

1:12 PM

I learnt that atleast my textures seem to be upside down:

user92578

Jon

if your projection is inverted

getting closer looks good

user92578

getting closer... was doing vector * matrix in the shader instead of the supposed matrix * vector

Jon

cool

Jon

1:37 PM

wrote my serializer

wrote my webservice skeleton... wrote my model draft

wrote my web test

running this now -- at this rate i'll be done by noon

SpartanDonut

yay?

Jon

hell yeah

7Blue_Beast7

2:18 PM

@Tyyppi_77 Hi

user92578

for some reason the texture coordinates are not ever in the correct order the first time

SpartanDonut

There he is

user92578

@7Blue_Beast7 Hey

7Blue_Beast7

@Tyyppi_77 Hows your game been going?

user92578

finished it as a prototype like a month ago

Jon

2:19 PM

supernova apparently

7Blue_Beast7

nice.

Blue

Hey @SpartanDonut

user92578

now I'm working on turning the code of it into a framework for me

SpartanDonut

Blue!

Jon

you gonna share it?

user92578

2:20 PM

that has OpenGL rendering so that I can create amazing shader effects

Jon

or keep it all to yourself?

user92578

Not sure yet

Blue

How are you doing bro?

7Blue_Beast7

@Tyyppi_77 So I set a course for my self

user92578

What did you choose?

Jon

2:20 PM

I was thinking about releasing my 2d tile engine

SpartanDonut

@Blue Keeping busy. Check it out - intellisenseless.com/Media/Games/TwinStickTest/index.html

7Blue_Beast7

Im headed for Quantum Nanobiology and Game Development (For creating a company).

Jon

its a lot of work for me to do it, so its on a backburner

7Blue_Beast7

I'll be able to handle with Reality and Virtual Reality

Jon

today?

7Blue_Beast7

2:22 PM

My dad is suprised I said that

Blue

@SpartanDonut frametrapped.com/installers/3.0/FrameTrappedSetup.exe

7Blue_Beast7

@Jon Hm?

user92578

So I need to be able to render like general boxes and stuff in OpenGL, so I guess I need to make a separate shader for rendering geometry like that? I need atleast a box with just an outline and then a filled box too

SpartanDonut

@Blue what are the hot new features?

7Blue_Beast7

@Tyyppi_77 So you are still working on the game right?

user92578

2:24 PM

Not really

Blue

@SpartanDonut it works.

Jon

ok, how do i get more winter jam hats?>

Blue

That's what :P

user92578

I'll probably do a full game like it one day, but now it's just a really bad prototype

SpartanDonut

@Blue haha. I presume it works with Ultra now despite what the home page says?

7Blue_Beast7

2:25 PM

So what are you working on now?

SpartanDonut

oh my goodness I forgot that with my new found 2k rep I don't need approvals for edits :D

user92578

As I said, I'm turning the GunHero code base into a C++-framework for more rapid development for me in the future. Currently I'm working on implementing my own OpenGL rendering instead of the bad SDL rendering

Jon

I think that is a pretty good path

Just promise me you end up making a game with it

user92578

I promise

user92578

I just need an idea for a game

Blue

2:32 PM

@SpartanDonut yes.

SpartanDonut

Nice

7Blue_Beast7

@Tyyppi_77 Sadly, I am still using blender for school projects :C

user92578

Is there something wrong in using Blender for games in your opinion?

7Blue_Beast7

No, but it would be dumb idea to have my employees in a game company using it

Jon

i think its fine if you are good at it for prototyping

how do you release a blender game?

7Blue_Beast7

2:36 PM

Use the Game Dev Release Addon

Jon

what does that do?

7Blue_Beast7

They are linking to the web so you can save the game and then send it where you want it

I don't know if they'll let you be super specific on where you send your game to but it allows other user to play it.

Jon

how do they play it?

do they need to install a blender player?

7Blue_Beast7

Nope

It'll be like any other downloadable game

With in-game instructions to.

Sadly, they haven't planned on implementing it in blender yet but you can instal the add-on to blender

Jon

so what is it pc only?

7Blue_Beast7

2:41 PM

PC and Mac

For Science i get to design a Future car and write down the actual designs and stuff for next semester

However there is a class for Hgih School that offers you to create stuff with CAD

user92578

Slowly getting closer:

user92578

I added this really simple but really usefull feature: you can edit shaders run-time and just press f5 in-game to reload the shaders

SpartanDonut

@Joe did you ever come up with a solution to this problem? gamedev.stackexchange.com/questions/83617/…

Joe

2:57 PM

^ I was actually drawing my joysticks with main camera on right on the gui i never had that issue

user92578

...and closer:

user92578

SpartanDonut

@Joe I mean this sounds like the same issue you had with the inventory

At least as far as what I reproduced of that issue (WASD interfered with input events which would be the same as joystick)

Joe

@SpartanDonut OO Inventory

submit an answer lets see if that does the trick for him

its similar but i dont know if its perfectly relevant

SpartanDonut

3:12 PM

Well it was asked in September so who knows if he'll even read it

Joe

good call on the relevance though

SpartanDonut

But I give you a vote and that makes the question answered by our standards

Joe

hey im always happy to put in an answer if I can honestly say I grasp whats going on

but im still pretty green, to unity dev at least

Jesus Christ

Hey guys I have a little question. I have a shader with 3 mat4 uniform objects.

But only one I can get through glGetUniformLocation. Names are correct, I checked thousand times.

Why is that so?

uniform mat4 u_WVPMatrix;
uniform mat4 u_WMatrix;

matrixTransform = glGetUniformLocation(program, "u_matT");
WVPMatrixUniform = glGetUniformLocation(program, "u_WVPMatrix");

worldMatrixUniform = glGetUniformLocation(program, "u_WMatrix");

user92578

what's the error? or are the locations same?

Jesus Christ

3:24 PM

only WVP is loaded. UWMatrix equals -1.

What do you mean locations?

user92578

the locations glGetUnformLocation returns

Jesus Christ

WVPMatrixUniform = glGetUniformLocation(program, "u_WVPMatrix"); return 1, but worldMatrixUniform = glGetUniformLocation(program, "u_WMatrix"); returns -1.

I expect worldMatrixUniform = glGetUniformLocation(program, "u_WMatrix") to return 1

u_WMatrix present in shader as uniform mat4

@Tyyppi_77 any ideas?

user92578

like they should be different

user92578

but the data is not getting passed around?

user92578

the order of uniforms in a shader file doesn't mean the location of it

Hippalectryon

3:32 PM

@JesusChrist :O you're back

I've been waiting 2014 years for you :3

Almo

don't you mean 1981 years?

Jesus Christ

@Hippalectryon yes, I'm here

Hippalectryon

Uh true

Almo

:)

Jesus Christ

@Tyyppi_77 I mean why it returns -1 when uniform is present in the shader file?

-1 means that it is not present

but it's present. what'a helll

7Blue_Beast7

3:33 PM

@JesusChrist Hi

Jesus Christ

@Hippalectryon Do you want me to cure all of your diseases? Maybe some relatives you want to resurrect?

@7Blue_Beast7 Hi

SpartanDonut

Just some wine please.

Hippalectryon

Anyhow. I'm using python 2.7.X to run this program https://raw.githubusercontent.com/weeble/clockworkcodex_minemap/master/minecraft_mapping.py but I get the following error : `File "C:\Users\Hippa\Dropbox\MC to RBX\mcToLua.py", line 36, in arrange_8bit
return numpy.fromstring(data,dtype='u1').reshape((16,16,128))
TypeError: argument 1 must be string or read-only buffer, not bytearray`

How do I fix that ?

@JesusChrist If you could cure that program >.>

Jesus Christ

@Hippalectryon pass a string or read-olny buffer?

7Blue_Beast7

@JesusChrist You like music?

Jesus Christ

3:35 PM

*string

@7Blue_Beast7 Yes

SpartanDonut

press the up arrow to edit

7Blue_Beast7

@JesusChrist Thats a nice but rare seen online

Jesus Christ

@7Blue_Beast7 Who, me?

7Blue_Beast7

@JesusChrist Yeah

Jesus Christ

@7Blue_Beast7 Yep, I do rarely went up here.

Hippalectryon

3:36 PM

@JesusChrist I'm not too sure, the program (not by me) uses some nbt module I have never used before. I haven't found anyone else with the same problem on that program on google.

Jesus Christ

@Hippalectryon well, you simply have a type error, it's not really that hard to fix it, I think. just give it what it wants.

Hippalectryon

@JesusChrist That's easy to say :/ I don't know how to give the right type without breaking the program

Jesus Christ

@Hippalectryon simply convert it. Write a function that converts given type to required. And pass the result of that function to your problem place.

Hippalectryon

:O

I didn't edit anything and it seems to work now

wut

Jesus Christ

lol

Hippalectryon

3:43 PM

@JesusChrist You do miracles

Jesus Christ

@Hippalectryon I'm Jeezus, after all

Hippalectryon

Hmm nope.avi

It's still not working after all :/ I'll convert

How do I convert bytearrays to string ? (I did search google, didn't find a relevant answer)

I doubt str(bytearray here) will work

Almo

probably involves encoding

like UTF8 type shit

Jesus Christ

@Hippalectryon I can tell that solution exists.

Hippalectryon

@JesusChrist You sound like a mathematician

Jesus Christ

3:48 PM

@Hippalectryon b"abcde".decode("utf-8")

Hippalectryon

I know that's the result n1 on google

But I'm not sure if that will work

Jesus Christ

Try it?

Hippalectryon

Let me look at numpy.fromstring

numpy.fromstring(string, dtype=float, count=-1, sep='')
A new 1-D array initialized from raw binary or text data in a string.

Then why doesn't it accept bytearrays :c

Logicz

Almo

am i the only one who reads "numpy" like "lumpy" rather than "num pie"?

Hippalectryon

Probably :3

Almo

3:50 PM

:D

SpartanDonut

Nope. I did the same thing

Almo

I didn't know what it was for a long time

till I noticed it was always in connection with python math questions

Jon

numptin.sumptin

Jesus Christ

how in the hell one can debug open gl?

Yann

@JesusChrist One does not simply...

Jon

3:51 PM

isn't the second coming of christ suppose to trigger the apocalypse?

SpartanDonut

@Hippalectryon because a byte array is not raw binary data or text data in a string

Almo

pocky lips if you believe Mad Max 3.

SpartanDonut

> in a string

Almo

kids ruined that movie >:(

same for Jurassic Park >:(

Jon

he wasn't even mad

should of been called "Survivalist Max"

Hippalectryon

3:52 PM

But using the code below raises other errors in the code, so I doubt that's how I'm supposed to do it

newDat=data.decode("utf-8")
return numpy.fromstring(newDat,dtype='u1').reshape((16,16,128))

7Blue_Beast7

Um.... what? @Almo

Almo

he was "angry" not "crazy"

Jon

i'd be angry too if people kept trying to eat me

Almo

so Mad as in I'm really mad at you!!

7Blue_Beast7

@MLM you okay?

@Jon you make me angry when you say that

Jon

3:54 PM

however is angrier wins

SpartanDonut

@Hippalectryon often times one error will mask other problems

@Jon Whoever*

whomever

ugh.....

@SpartanDonut I still don't know what to do though :/

7Blue_Beast7

3:55 PM

@Jon whatever

SpartanDonut

You solved one problem. Move onto the next one. That's what

Hippalectryon

UnicodeDecodeError: 'utf8' codec can't decode byte 0xdd in position 0: invalid continuation byte

newDat=data.decode("utf-8")

SpartanDonut

I'm going to guess and say your byte array is either not a string or not utf-8 encoded

Hippalectryon

level = nbtfile['Level']

skylight = arrange_4bit(level['SkyLight'].value)

^ that's what is being sent

SpartanDonut

well I'm finding very little / no documentation on the arrange_4bit function

but I think I found the sample you're using :P

Hippalectryon

3:59 PM

@SpartanDonut I put the pastebin before

raw.githubusercontent.com/weeble/clockworkcodex_minemap/master/…

That's the exact file I'm using, with added at the end :

volume_factory = VolumeFactory()
region_volume = volume_factory.load_region(
		'map/r.0.0.mcr')
map_rgb_array = numpy.zeros((512,512,3), dtype="u8")
map_rgb_array[:,:,0] = region_volume.blocks[:,:,70]
minecraft_map = make_surface(map_rgb_array)

SpartanDonut

ok

Any clue what the actual value of level['SkyLight'] is?

Hippalectryon

It's a bytearray

It contains the map skylight's data

Jon

eurogamer.net/articles/…

Almo

i'd like to shoot the next writer who says "blah blah, wait for it, blah blah"

Jon

seems like a reasonable goal to have

Almo

4:20 PM

pointers in a nutshell: "A good thought-picture: Values are like Stuff. Variables are like boxes that you can put Stuff in. Pointers are like index cards on which the physical location of boxes are written - note that the index cards are a kind of Stuff, and could also be put in boxes."

user92578

4:33 PM

what's the correct order for matrix multiplication with a translation, a viewport and a resolution matrix?

Lasse

@Tyyppi_77 do you mean model, view and projection matrices?

user92578

I don't really have those

Jesus Christ

@Tyyppi_77 MVP = model * view * projection.

view matrix = inverse (rotationZ * rotationX * rotationY * translation)

user92578

I have a matrix with the offsetting of the rendering process. Then I have a matrix with orthographics projection, and then I have a matrix with the correct scaling factor for resolution

Lasse

what's the scaling matrix for? you have some weird device coordinates?

user92578

4:38 PM

everything that is drawn is scaled by 3, but that will probably change

Lasse

the orthographic projection should convert the coordinates to -1 -> 1 range, which is device coordinates range

user92578

that is to achieve correctly sized tiles

Lasse

you are probably doing it wrong then, zooming the whole screen in so that it's three times larger

you should instead scale up the objects with the model matrix

user92578

ah, okay

Lasse

the offsetting matrix sounds like model matrix, just add a scale to it and you're done

user92578

4:41 PM

an uniform model matrix won't be good for batching that will come next, or will it?

Lasse

by uniform do you mean a model matrix that's equal to all other model matrices or a matrix put in to a uniform in shader

user92578

matrix put to a uniform in shader

user92578

but I guess that is nothing to worry about right now

user92578

projection would be the orthographic matrix, and model the object's matrix. could the scaling go to the view matrix or what would that be used for?

Lasse

view matrix is usually the camera

@Tyyppi_77 batching is something that groups similar objects together so that minimal amount of GL state switching is required to draw every object on screen, like objects with same texture and same shader

Blue

4:52 PM

I love my hat.

Lasse

and you can happily use uniforms to give the shader the model matrices when batching

Almo

hat i used last year was the cop hat for raising flags

Lasse

it's only after you start drawing a lot of similar objects, like 10k or so, you will need something more optimized

Jesus Christ

btw I came to understand why i never get my second uniform. It's because it was optimized away by the shader compiler.

user92578

strange

Lasse

4:58 PM

yeah they get optimized out if the end result will not affect the output of the shader

Jesus Christ

it was gonna affect the varying variable, that was supposed to be used in a fragment shader, but fragment shader was never supposed to use it. So it was optimized away.

varying vec4 v_fragCoord it was called.

shader compiler is damn good at optimizing.

Lasse

lol I wrote a funny sentence there, I ment that if the uniform does not affect the end result of the shader it will be optimized out

thanks for the star so I read it again

SpartanDonut

5:22 PM

@Almo I actually think this might have been how it was explained to me (or very similar anyway) when I was taught pointers. As a result I feel I don't struggle too much with the concept. Implementation and syntax is another story though :P

user92578

any ideas why it takes 3-8 seconds on startup to actually launch the program when I use the default visual studio debug mode

user92578

it goes down to 1-2 if I start without debugging

SpartanDonut

If it was .NET I'd say attaching to the process and loading symbols takes time

Not sure how it works with C++

user4704

Same thing.

user4704

More or less.

user92578

5:24 PM

how could I speed it up?

user4704

The debugger has to attach and do stuff, talk with the hosting process, et cetera.

SpartanDonut

And perhaps not just loading symbols but building symbols

user4704

Oh dear.

user4704

The pictures from the Christmas party have arrived.

OMGtechy

5:43 PM

@AttackingHobo oh wow (the projector)

cnet.com/news/…

Almo

6:20 PM

@SpartanDonut haha yeah syntax

SpartanDonut

The more I think about C++ the more I feel VB had some good ideas :P

Almo

:D
