nice

you got people testing it atm ?

Does anyone know a good book on CG shader programming ? Specifically for Unity ?

or good resource generally ?

hi

Martin Sojka

Damn it, why does Github need to be so strange? Created a new branch on my fork of a repository from a specific commit in the Github web page. Can't find the branch in the desktop application. Can't find any way to synchronise this. Can't find any documentation explaining it all.

Anybody got a hint?

Surprisingly ... changing the branch to an older one, then changing back to "master" helped. WTH, Github?

Martin Sojka

07:59

Next hurdle: Get Github Desktop to apply a patch ...

... which doesn't work, you need to go back to the shell it seems. So far, the application hinders my productivity more than it helps.

user92578

08:34

I would probably use the desktop application if A) GitHub allowed a few private repos by default and B) If it had a dark theme

user92578

Also, I hate when a page uses nested scrollbars. The e-book site I read my religion course book from uses those, and it is really fricking annoying

user92578

Is that how you spell "fricking"?

user92578

It seems so

user92578

Yeah, so to the source control thing, I only use BitBucket because it generously allows me to make a repo Private, without tediously trying to apply to some stupid student program.

user92578

I feel like GitHub's UI is superior to the one of BB's

Martin Sojka

08:40

@Tyyppi_77 I typically use "friggin'"

And I didn't dare to try cross-repository cloning yet, so I'm mostly stuck with Github for the projects I wish to contribute to.

I still have no idea how to refresh the branches' list, by the way. It just does after a while.

data of heightmaps are in int. how should it feed the data in vertex shader? should it process the heightmap value to float or it should be left to opengl to handle the normalization?

Martin Sojka

I assume you want to have the heightmap as a texture inside the shader?

fallenAngel

I am just learning opengl. I am not sure what you are asking. I am following opengl superbible and I am not yet reached textures.

I want to do something practical before moving forward

Martin Sojka

Well, a heightmap is typically a 2d data array, so making it into a texture (image, essentially) is how non-trivially sized ones are used as an input to the shader.

That said, there are alternatives for specific cases.

Like, you could as well make it from a temporally-dependent procedural noise function directly in the shader.

(This is how things like "moving water surface" are created, as an example)

fallenAngel

I have already a heightmap in .bmp. and I have array of pixel parsed from it. I just want to feed those data in vertex shader without any texture, effects. Just plain boring single colored terrain.

Martin Sojka

The important thing to note is that when you use a texture is that most modern engines will use EXT_texture_sRGB, and for a heightmap, that's exactly what you don't want - you want the values to be linear - so you have to tell them that.

Jon

09:09

Them, being the little electrons flying around in your processor

Martin Sojka

If you do your OpenGL calls yourself, using the GL_RGB8 format is just fine.

fallenAngel

@MartinSojka so what do you recommend? how should i proceed?

Martin Sojka

The shader language will just translate it to floating-point values in the [0,1] range generally.

fallenAngel

So basically i can pass array of int in vertex shader and opengl will make it float internally?

Martin Sojka

@fallenAngel Bind a heightmap texture as RGB8, use uncompressed data or something which works well with heightmaps like BC4, displace your vertices by one of the texture channels multiplied by the maximum height of the landscape. Should work fine.

That's a bit different from passing an array of ints, but also usually significantly more performant as well.

Jon

09:16

anyone know if I can install Windows 10 Upgrade on a new PC?

if I never upgraded this PC, and I want to transfer to new one

Martin Sojka

I'm not touching any Windows before SP1.

user92578

I can't wait to get home and do more work on the level editor

user92578

But there's till an hour before the last class starts...

Almo

11:19

@Tyyppi_77 "fricking" is one usage, though "frickin'" is more common

@MartinSojka release is alpha, SP1 beta, SP2 RC1.

Jon

Man...

you need to spend a good 20 minutes to setup windows 10 privacy

and you can't turn off Cortana

which for some reason, uses up 90MB or ram

and I have no idea why I can't turn it off

Kevin van der Velden

You should be able to, it is another privacy option I recall

Jon

46

Q: Can I completely disable Cortana on Windows 10?

Windows 10 has Cortana, which I don't like. I disabled it as soon as I could. However, looking in Task Manager, the process for Cortana is still running, and can't be effectively terminated: ending the task simply results in the process respawning a few seconds later. Using the command taskkill ...

even with the removal method, you cannot remove it

Kevin van der Velden

Huh

user92578

11:58

Finally home!

Volatile

hi

user92578

Hi

Volatile

12:10

typii what type of game you making

user92578

It's a platformer action shooter

Volatile

is it like carl on duty

user92578

no

Volatile

is it like world of mario

user92578

well a bit closer I guess

user92578

12:13

Hold on, I'll get you a screenshot

Almo

@Jon yeah, what a horrid name

user92578

Volatile

oh so it's like sonic the turtle

user92578

no

Almo

lookin good there

user92578

12:16

thanks, nothing new tough

user92578

trying to finish homework so I can get back to the level editor

user92578

How would you suggest implementing erasing?

user92578

My current architecture is that Brushes act like the Command-pattern, so that they have an Execute() and an Undo() method.

user92578

Brushes can place several tiles (like the main terrain brush will place the background tiles, then the tile noise, and then the grass layer if the tile is on the top row)

user92578

So that's why a generic EraseBrush won't work, because the brush needs to know what tiles a tile has "relations" to

user92578

12:22

I'm thinking about adding an Erase() method to every brush... other ideas?

user92578

However, I'd need to separate the Erase from the Place brush instance for the Undo to work

user92578

so, a boolean to the TerrainBrush constructor to indicate erasing?

user92578

Tyyppi with the class names at it again: TLevelEditorBrushTerrainTileData

user92578

12:44

The new parallax layer images I added are slowing the launch time up a lot :(

user92578

At load time, I load all the contents the game uses to memory

Joe

Guy behind me on the train has been talking for 30 minutes on the phone about what hes going to do with the 100 million dollar lottery when he wins it. talking about how he needs it and its going to happen

if he planned this much shit about his actual life i guarantee he'd have a higher paying job...

user92578

lol

Almo

hahahaha

Joe

idk why but its pissing me off haha

Almo

12:48

Firefox seems slow. Damn "System Idle Process" chewing up 95% of the CPU again...

Jon

sounds like someone needs to upgrade to skylake

user92578

If I declare a 2D C-like array in C++, why can't I set a single array in it?

Almo

ff has 1.8 gb allocated?!?

user92578

I can't do array2d[0] = {stuff_here}

Almo

i only have like 15 tabs open...

restarting it.

user92578

12:49

But I can do array2d[0][0] = first_stuff

Lokkij

Browsers eat RAM like crazy man

Almo

restarted

much better

Joe

^ for now

Almo

well, it's been on since monday

I only shut down my PC on friday

Joe

"that shit costs 75 dollars a shot?! imma pay for my own bottle, screw 75 dolla shots"

no wonder you need a 100 million lottery winnings, you have credit card debt from the liquor store

user92578

12:54

I can't even modify an array in a std::map<ELevelEditorTileType, unsigned int [6]>???

user92578

m_TileOverlayData[ELevelEditorTileType::BACKGROUND_JUNGLE]= {256, 257, 258, 259, 260, 261};

user92578

"Expression must be an modifiable lvalue"

Almo

array = {sdkfjksdjfkfsl} is just a static initializer

and is done at compile time

I don't think you can do those anywhere but in definitions

user92578

Okay

user92578

Sooo

user92578

12:58

std::vector it is then I guess

Almo

yes

:)

user92578

or rather std::array

Almo

vector more likely.

user92578

well no, the size is constant

Almo

uh ok

user92578

12:59

std::map<ELevelEditorTileType, std::array<unsigned int, 6>>

user92578

I mean doing this

Almo

I don't know what the benefits are over allocating a vector with an initial size

user92578

I guess I could dump the map and just use an array

user92578

Yeah, this'll be the first time using std::array

user92578

Okay, small progress update:

user92578

13:01

user92578

There is no Z-ordering or erasing yet

I think I need to add an awesome custom mouse pointer too :D

looks cool dude

user92578

13:27

Thanks

Almo

I remember when I first got that working on the C64 for a land map generator... with flood fill to find water bodies

was pretty stoked

implemented a form of recursion using an array as a stack

didn't even know what recursion was. I think I was 16 or something

user92578

:)

Jon

You are the inventor of recursion!

Almo

hahah

I did invent implicit differentiation in calc class

teacher put up an equation and said how would you do this? I said well, you got y' on the other side, why not just algebraically move it over?

he said "let's try that" and it worked

I suppose "invent" is the wrong word, but you know what i mean

user92578

figured out without external help?

user92578

13:31

yeah, that sounds awesome tough :D

user92578

I actually finally learned what derivatives are in math class today

user92578

Super exited about it

Almo

:D

when you learn some of this calc stuff, things in game programming start to look different

user92578

user92578

(not quite sure if you're being sarcastic, but) thanks tough :D

Kevin van der Velden

It's someone with a really broken nose being really happy (presumably because they're high on pain killers)

Almo

Jon's not sarcastic very often, and when he is, it's usually with regard to politics

user92578

okay, that's a good rule of thumb to keep in mind :D

user92578

14:27

Is it "Undo -> He undos" or "Undo -> He undoes"?

Almo

"undoes" I would say

not sure if it's "correct" though

user92578

BTW Does the pronounciation differ?

user92578

yeah it seems to

Almo

@Tyyppi_77 yeah it would

undoes would sound like "uhn duhz"

undos would probably be "uhn dooz"

user92578

LOL I just love when people spell out pronounciation :DDD

user92578

Thanks tough

Pip

undoes is correct IIRC

Yeah, spellcheck agrees with me.

Almo

sure

user92578

15:09

Z ordering works!!!!

user92578

Almo

cool

user92578

Yeah it works pretty great, one ugly thing is that I have to map two enums together

user92578

if (m_TileType == ELevelEditorTileType::BACKGROUND_JUNGLE) levelLayer = ELevelLayerIdentifier::TILE_BACKGROUND;

user92578

From the editor layer to the actual level entity layer

user92578

15:14

But yeah, a std::map will make that a bit cleaner

user92578

That's because I will need more layers in the editor than in the level to store the data

user92578

Okay, so that's working

user92578

Now to the grass placement

user92578

nah

user92578

I think Ill just call it a day
