05:00

Ah, I see.

melak47

but just wrapping crap where it's owned in ComPtr means you don't have to remember to release it at the right time

ThePhD

Indeed.

melak47

texture goes out of scope? released by destructor :)

you don't have to use it, but it hasn't hurt me so far

ThePhD

November CTP, or are we doin' this old-school like the old-school?

melak47

either way is fine

old school until we need/want something from the CTP?

ThePhD

05:03

Oh

Giggles. Too late, it's already CTP. x3

VARIADICS 4 U

melak47

how do I tell VS again to not dump the sdf and whatnot in the solution dir?

ThePhD

Um

Tools -> Options -> SomethingSomething

melak47

there was an override dir option somewhere.

ThePhD

Text Editor -> C/C++

melak47

ahh

ThePhD

05:04

Advanced -> Fallback Location -> Always Use Fallback Location {To: True}, Do Not Warn if Fallback Location... {To: True}, Fallback Location {Something frivolous, like "D:\Visual Studio Scratchspace\"}

melak47

C:\TEMP :3

ThePhD

Roflmao. Like a boss.

melak47

or maybe I'll point it at the recycle bin, lol

ThePhD

Haha

Well, not quite.

C++ uses those, and the Recycle Bin is protected space.

You might blow up Visual Studio. :P

melak47

do you want to keep build files in a "build" folder or something?

by default it dumps crap everywhere, doesn't it :/

ThePhD

05:07

Right now I have almost all our includes / sources in {TopLevel}/SolarStar

Build files are currently in {TopLevel}. Could make a build dir, though, if it makes you feel better. :D

melak47

makes it easier to delete

I mean stuff like build outputs, object files etc

ThePhD

Mmkay

melak47

don't need them in the same location as the sources

ThePhD

By default, they don't be.

Visual Studio should seclude them off into Debug / Release folders in the Solution Directory, usually.

melak47

well, then I guess, whatever

ThePhD

05:08

Well, my solution is closed.

Move it if you like. :D

melak47

do you have precompiled headers on? or why do we have a giant include list :o

ThePhD

No precompiled headers.

I just made an empty project, so it's barebones-nothing.

I've never used PCH, you can turn it on if you like. But PCH has only given me major headaches.

melak47

doesn't including everything slow down compilation?

nah I don't know how to use it properly :p

ThePhD

We're only including standard headers: the compilation time will be swift. Just hit F7 and see.

Can I open the solution now?

melak47

yup

had a look around, but it's closed

ThePhD

05:11

Well, open it up again.

We both have to be editing it at the same time for this to be productive, silly. :P

melak47

will that be ok? I mean, what if you change something, compile, dropbox syncs...

ThePhD

I'll create a new Project / Solution Configuration

That way you can have Debug all to yourself, and I'll have PhD Debug all to myself.

melak47

heh, ok?

I see unicode is off

ThePhD

What this'll do is all my compilation files (object, linker, etc.) will go in a separate directory

melak47

means I can delete those stupid L prefixes

ThePhD

05:13

We're gonna turn tha tshit on, because UNicode Is Life.

melak47

...spoke to soon, lol

ThePhD

Haha. x3

Sorry, just. After using Unicode, don't want to go back.

Nooo ooo oooo can't go baaack

melak47

yeah I suppose

feel free to criticise my inconsistent naming of functions

ohmagerd, what's this

what are those macros at the top?

(#@b1) << 8

?!?!?

ThePhD

#@b1

Means you can type

charcc4(R ,I ,F, F)

And it will automatically turn them into chars

#@ is the Charizing Operator for Macros

melak47

okay O_o

ThePhD

05:20

These are just some

helpful platform defines and macros

melak47

do you prefer to link to D3DCompiler.lib etc in the project settings?

ThePhD

Usually, but it's too late for that now: we already got a #pragma lib comment, so it's all good

melak47

haha

ThePhD

I might move to to Platform.h, though

Just so if we need any libs or stuff, we just #include <SolarStar/Platform.h>

I forgot

how to tip the whole system off

that you're doing

WNDCLASSEXW stuff

melak47

?

ThePhD

05:25

And not WNDCLASSEXA

melak47

I use A so I don't have to use L"bla" xD

because wchar_ts are a pain if they're not literals :p

ThePhD

Well, this is just for Window Initialization

So we can do it so we can have fancy Japanese Solar God Names in our window title. :P

After that?

ASCIIASCIIASCIIASCII

melak47

ok, I'll change the constructor to take a ....LPTSTR? for the title

LPTSTR should become a LPWSTR with unicode, right

ThePhD

Just do std::wstring

No point make it hard on ourselves. :P

melak47

ok

feel free to change the default argument window title

I think we will need to link DXGI.lib also

ThePhD

05:31

Yerp

melak47

oh wow, this is spooky

I think by syncing stuff, I get your undoes

I ctrl+z'ed in Platform, and it undid the #pragma comment(lib s, even though you placed them there :o

ThePhD

Really?

Freaky. :O

Tools -> Options -> Environment -> Documents

Detect when file is changed outside the environment (and Auto-load changes, if saved)

melak47

no more asking boxes

ThePhD

Only if you've already saved the file.

if not, it'll ask.

melak47

that makes sense yea

"oh you were typing something? I'm sorry I just loaded it from the disk for you :D"

ThePhD

05:35

Lols

melak47

ok, changed some includes around

do you want to IM or do you want to keep talking here?

ThePhD

Well, I keep trying to type messages but it's telling me I'm dumping them out too fast. D:

I, uh. Don't really have any IM programs though, lmao.

What do?

melak47

haha

oh, also, you can throw your Texture class in there

ThePhD

Still trying to figure out how to use this GPUBuffer thingy

Also, what's this Front, at, back, etc. for?

melak47

it wraps a std::vector...sort of :D

ThePhD

05:42

OOH this GPUBuffer contains a std::vector of internal data

melak47

and automagically uploads it to the GPU

ThePhD

Shiny.

My texture class was a bit more... involved, I think.

melak47

but it also works for constant buffers, where it only contains a single item

well, this is only half implemented as you can see

but I haven't needed the other options yet

ThePhD

Mmmhmm, mmhmm.

Let's see here...

melak47

GPUBuffer<Vertex, D3D11_BIND_VERTEX_BUFFER, 0, 0, D3D11_USAGE_DEFAULT, BufferUsage::Forever> VertexBuffer;

this is how it would be used

where Vertex would be a vertex struct/class

and Forever means it never changes

ThePhD

05:45

Oof. All my thing requires a GraphicsResource, which requires another thing, which requires another thing...

Maybe I can strip some dependencies.

melak47

also, if you try to use GPUBuffer wrong it'll throw nice compile time errors at you :)

I hope.

ThePhD

Indeed, very nice static_asserts and all

melak47

basically just wrote down the notes for those parameters from MSDN

but I'm lazy and this way I don't have to look it up xD

ThePhD

Hehe

Any ideas for a messenger client?

melak47

well, pick anything

msn, icq, skype, trillian/astra

ThePhD

05:52

I have none of these things, so it's up to what you've got, really. :3

Also, you don't have a kind of

"GraphicsResource", do you? Where the constructor takes a holds a reference to a the Device and DeviceContext?

melak47

?

oh

ThePhD

Or is that always by constructor?

melak47

not really

ThePhD

Alrighty, by constructor it is.

melak47

I just keep Device and DeviceContext in everything that needs it lol

do you inherit from GraphicsResource?

this "engine" is neither proven through practice nor was it planned/designed, so don't be afraid to suggest changes

ThePhD

05:56

Things like GpuBuffer, ShaderResource, etc. etc.

All inherit from GraphicsResource, so they always have access to it when they need it.

GraphicsResource takes a GraphicsDevice (Or in this case, D3dRenderer) by default

And keep a reference to it.

melak47

ok

ThePhD

I don't expect a lot of GpuBuffer-based or Texture-based things floating around,

so the holding reference makes it easier to work with.

And the overhead is negligible, because you're not making 100000 texture/vertex/index buffers.

melak47

hehe

so does everything inherit from graphicsdevice, or does everyone keep a graphicsdevice?

ThePhD

Everyone keeps a reference (pointer) to GraphicsDevice.

They can then boil that down to whatever they need on their own (device->DeviceContext, device->Device)

To shock-update me, hit Ctrl + Shift + S

And it'll let me know the project has changed

and whip me into shape.

melak47

oops. F5 does not refresh the document. lol

ThePhD

06:06

x3

melak47

can you do that? address of the reference'd one you got as an argument? don't you like, get the address of a temporary or something?

ThePhD

If you pass something down by reference, then no temporaries are made.

If you pass something by value, then a a temporary is made.

References are meant to avoid copies.

melak47

hm, yeah, makes sense.

ThePhD

Oh shit, we have no entry point, haha.

melak47

yeah :)

which kinda man are you...WinMain or main() or main(int argc, char* argv[]) ?

ThePhD

06:09

The third. WinMain is for Windows GUI apps. We're making our own windows here.

melak47

:)

thankfully, my window class doesn't need the HINSTANCE

in fact, you can create a window with no arguments at all :p

though we probably want our own WndProc at some point

ThePhD

WndProc should be handled by the Window class.

To get messages we want, we'll add a NextMessage function on the Window class, so we can externally poll for events without worrying about the WndProc actions.

Ooh, you take a function pointer.

Savvy.

melak47

can change that though and define the WndProc as a class member

ThePhD

Naawww.

That's fine enough. Albeit, our WndProc will have to be a static function to work with that, but that's fine.

melak47

I've wrangled it to be a class member before :3

sort of. I think

ThePhD

06:15

Haha.

Well, it could get complicated fast if we do it that way.

melak47

stored a pointer to the window class instance inside the actual window

that way the static Wndproc had access to the window instances :p

ThePhD

And what happens when you make multiple windows? :P

melak47

each window has the class instance it belongs to stored inside it

there's some user memory in the win32 window

where you can stuff the pointer

so in the WndProc you know the hwnd of the window, and fetch the pointer from the window

but we can worry about multiple windows later :p

ThePhD

Mmhmm

melak47

so, where are we gonna put the entry point

ThePhD

06:20

Uh

Somewhere at the top, I guess!

melak47

lol

looks like it's all the way at the bottom :)

ThePhD

Heh

melak47

I added a D3DRenderer->Present() function

so you don't have to go digging through renderer->framebuffer->swapchain

ho window title without WndProc :S, let me move the arguments around :p

ThePhD

Good choice

melak47

lol I hope I didn't save while you were compiling

ThePhD

06:28

You did. :P

But I got it.

DUN DUN DUN DUUUHHH

Shiny bright window.

melak47

hmm, something is wrong

window doesn#t respond to anything

oh, right

no messagepump

^_^

did you copy that from somewhere? looks familiar lol

ThePhD

Hm?

melak47

the clear

ThePhD

Naw. I just made it up on the fly.

melak47

hehe

well, I guess not much you can do different

ThePhD

06:31

I can't imagine people would clear the color differently than that, though.

melak47

I tried initializing the array inside there, too, first

I don't really care which chat client/protocol you pick, I'll just use it inside trillian :)

ThePhD

Uh

Okay guess I gott amake an account somewhere.

melak47

I don't know which service asks for the least amount of personal data

microsoft probably knows everything about you anyway :p

ThePhD

Hum.

Alright

Trillian is... ... live

melak47

I'm...wait for it.... melak47

ThePhD

06:39

GASP

michael.bartnett

07:59

any ANSI C experts here that could confirm I can't have my cake and eat it too? that is: you can't allocate a single contiguous multidimensional array that would require 2 mallocs and 2 frees?

melak47

08:10

2 mallocs & frees? o.O

michael.bartnett

08:21

as in, if you were trying to make a 4x4 matrix, one malloc for a float[16], and another malloc for a float*[4]

so you could iterate on i = 0..15, as well as access by your_matrix[3][2]

melak47

can you do something like that with a union? it would only have 1 malloc and free, but it might let you access both ways

michael.bartnett

wouldn't pointer locations overwrite the matrix data and vice versa?

melak47

?

both would operate on the same memory, isn#t that what you would want?

michael.bartnett

yes, but if i want to access via mat[x][y], that implies some sort of allocated arrays of pointers, right?

melak47

oh, hm.

could you...

michael.bartnett

08:28

fuckit. imma write indexer macros

matrices are float*s

melak47

union matrix
{
	struct
	{
		float row1[4];
		float row2[4];
		float row3[4];
		float row4[4];
	};

	float* mat[4] = {row1, row2, row3, row4};
};

I know you can't initialize like that in a struct, but initialize it so it has those values

via a pseudo constructor

would that work?

mat[0] would return a float*, so mat[0][0] would give you the fist one?

but no, that can't share the memory..

never mind, I give up, too

michael.bartnett

a sad day for matrices

i appreciate you helping out though. /cheers

melak47

just overload operator[]! :p

michael.bartnett

totes would. except for C. and i must remain pure

snake5

12:01

union matrix{ float f[ 16 ]; float r[4][4]; };

problem?

:D

melak47

and now how do you get is so that matrix mat; mat[2] returns mat.f[2], and not mat.r[2]

Raven Dreamer

@ToddersLegrande It is a new old gravatar. I had this 'round december - june of last year.

snake5

@melak47 overload the operator

mat[2] wouldn't return "mat.r[2]" anyway, though

matrix isn't an array/pointer type

melak47

12:16

@snake5 in C :p

snake5

you're using the wrong language

C isn't meant for writing custom syntactical sugar all day, that's what C++ is for. C is for getting shit done.

Mr. Beast

12:39

all hail C++!

Kikaimaru

did i ever told you about my language ReverseFuck? you write an inputs and an outputs, and genetic algorithms will try to produce a program in brainfuck :)

it works nice for programs like a + 1, and once i managed to make program that write "hello" (hello world is too long)

snake5

"genetic algorithms"?

Kikaimaru

yes?

Genetic algorithm

In the computer science field of artificial intelligence, a genetic algorithm (GA) is a search heuristic that mimics the process of natural evolution. This heuristic is routinely used to generate useful solutions to optimization and search problems. Genetic algorithms belong to the larger class of evolutionary algorithms (EA), which generate solutions to optimization problems using techniques inspired by natural evolution, such as inheritance, mutation, selection, and crossover. Methodology In a genetic algorithm, a population of strings (called chromosomes or the genotype of the genom...

snake5

I don't see how they fit here

Kikaimaru

brainfuck instructions are genes, and fitness is determined by how does output correspond to desired ouput

snake5

12:51

o.0

the easiest algorithm is to discard input and just write ouput...

second easiest: do a diff and generate the brainfuck code based on the diff output

I really don't see how genetic algorithms fit here (but perhaps I'm just thinking with real-life constraints in mind)

Kikaimaru

game creatures, uses genetic algorithms to modify code that creatures has in brains, so it usable in "real world" :)

creatures.wikia.com/wiki/Brain#SVRules

awesome game :)

BaSha

13:06

hi..can any one elp me in box2d game?

help

snake5

@Kikaimaru that's a completely different set of requirements

and I'm not talking about "usability of genetic algorithms"

I'm talking about "usability of genetic algorithms in code generation"

Kikaimaru

13:24

@snake5 yes i do too

they generate code with genetic algorithms

snake5

13:50

@Kikaimaru what I'm saying is that it doesn't make sense, even if it's true

Kikaimaru

14:23

it is true, as you can see on that link, and it makes sense, since its used in working game

why the hell does typescript allow me to use non existing variables or overwrite my parameters with local variables....

Almo

use strict;

I think that will solve the non-existant variable problem

existent

hmm

ok with a second "e"

Kikaimaru

well as it turns out, the variable is actually existent, since there are some cool named global variables like "name"

Well MVC 4 is pretty awesome (disclaimer - I have little experience with versions prior)

And the ability for it to create the database on the fly just by adding more code to your model == awesome

I wonder how it actually handles changes to the database... like does it blow away the data, add some default data, or what

michael.bartnett

@Kikaimaru do you have a reversefuck implementation lying around anywhere on the internets?

Jimmy

I'd like to see that as well

is there some kind of backpropagation or is it mainly just applying mutators to previously "close" programs by output?

Kikaimaru

17:58

@michael.bartnett probably not it was too long ago

ToddersLegrande

To answer my own question before -> It can do automatic migrations or you can code your own migrations of the database changes when you make changes to your model. Pretty cool stuff!

Nathan Wheeler

20:34

@ToddersLegrande I saw your question earlier, and that's what I thought it did, but I wasn't sure and I haven't messed with it a lot myself, so I didn't want to look a fool for saying either way

"It's better to remain silent and be thought a fool than to open your mouth and remove all doubt."

Mark Twain. great quote.

ToddersLegrande

I like making guesses with disclaimers myself

1

A: How can unrealscript halt event handler execution after an arbitrary number of lines with no return or error?

While I'd be very happy for someone else to come and give a more specific reason as I don't really have the facts to back up my claim, but it looks like this is a limitation of Broadcast. Alternatively you can write to the console or maybe update some UI elements depending on how you want to hand...

This was my favorite guess with a disclaimer if you check out my comment on the question

Almo

an he never even accepted it :(

have an upvote
