retiring my own tasks framework ... i got a few of the properties slightly wrong

after that I plan to have a crack at making my voxels smaller

I think the best I can likely do is 2 bytes

sometimes an array of booleans can be optimized to stick 8 of them in each byte. C++'s vector<bool> is supposed to do that, I think.

you just need to make the [] operator use some bitwise operations or something like that

more of a memory optimization than a speed one, though when memory bandwidth is a bottleneck (which is often), then it's a speed optimization too

Wardy

Yeh i'm considering a bunch of ideas ... it soon gets to a point though where you're doing more working out than makes sense because you over packaged you're ram

Icy Defiance

@MickLH I have no idea what's happening with that project anymore. I've just been assuming it's dead until Hobo shows up again. I'm still willing to work on the C# bindings for your engine if you need it, though, at least when I have some spare time.

Wardy

I still need the get and set of a voxels properties to be as fast as possible

Icy Defiance

lol this is odd. #include <functional> doesn't throw an error, but afterward I try to use std::function and it says that isn't declared

<functional> is where std::function is declared...

oh, right, old version of cmake, using C++0x instead of C++11

Pip

1:13 AM

@IcyDefiance @MickLH I've assumed that as well

Icy Defiance

you disappeared before hobo did though >:|

Pip

I had nothing to do at that moment

I was actually still hanging out in the chat room

Icy Defiance

I don't care about your excuses! now explain this error: /usr/bin/ld: ../glfw/src/libglfw3.a(x11_init.c.o): undefined reference to symbol 'XF86VidModeQueryExtension'

Pip

You have an undefined reference to symbol 'XF86VidModeQueryExtension', duh

Can I see your makefile or whatever?

@IcyDefiance

Icy Defiance

yeah, but it was generated by cmake, so I'm not sure it'll help. one sec.

Pip

1:22 AM

kk

also paste the cmake command thing?

Icy Defiance

pastebin.com/TxuKUW3E

the cmake files are on github here. there's 4 of them, one in the root directory and one in each of the 3 subdirectories: github.com/IcyDefiance/EngineCPP

Pip

cool

Icy Defiance

the error is being thrown while compiling EngineTest, though I have no idea if that's where the actual problem is

Pip

you have no inc folder in EngineTest

fyi

don't know if that's it or not

Icy Defiance

EngineTest only has one main.cpp file to compile and it doesn't have a header, so there's nothing to put in an inc folder

Pip

1:27 AM

try adding the folder though

Icy Defiance

with nothing in it? why?

Pip

It might be crashing because the folder is referenced but not there

just a guess, cmake is horrible to debug

Icy Defiance

oh hey, it is referenced, but no that's not the error. I just removed the reference and still get the same error.

Pip

hm

Icy Defiance

it worked on windows, so the problem is probably related either to dependencies or some compiler quirk

Pip

1:29 AM

you think you can get a copy of the makefile it makes? I can definitely work off of that

It's a dep thing

you're missing -lXxf86vm in your makefile, idk why though

Icy Defiance

the pastebin above is the makefile

Pip

kk

Almo

hey

lol time?

Icy Defiance

Almo it's torturous debugging time!

Almo

ok :)

i'll play a round of hots and check back

Icy Defiance

1:31 AM

I did see -lXxf86vm in some google result, and yeah it's not being used...not sure if it's required or, if it is required, how to add it

Pip

That's not the makefile I meant @IcyDefiance

I need the CMakeFiles/Makefile2 that's generated during the compile

Icy Defiance

ah okay. pastebin.com/bgR9TVB8

Pip

god damnit I can't find anything wrong with that. I also can't find any dependency injection, which has to be in a makefile somewhere

Icy Defiance

-std=c++11 -Wall -Wextra -Wno-long-long -pedantic -g    CMakeFiles/EngineTest.dir/src/main.cpp.o  -o ../bin/EngineTest -rdynamic ../Engine/libEngine.a ../glfw/src/libglfw3.a -lGLU -lGL -lSM -lICE -lX11 -lXext

those should be the compiler flags

and it is missing -lXxf86vm

question is how to add it...

Pip

yeah

Almo

1:36 AM

-std=c++11 -Wall -Wextra -Wno-long-long -pedantic -g CMakeFiles/EngineTest.dir/src/main.cpp.o -o ../bin/EngineTest -fuck -rdynamic ../Engine/libEngine.a ../glfw/src/libglfw3.a -lGLU -lGL -lSM -lICE -lX11 -lXext

Icy Defiance

why must you make my compiler swear? D:

Almo

:D

Pip

lol

why -Wno-long-long?

huh

Icy Defiance

uhh that one I don't know. it was just part of something I copied from stack overflow and it looked good, lol.

Pip

Anyhow, that's the flag you're missing, I have no idea where the rest are

Lol

where did you add those?

Icy Defiance

1:38 AM

in the root CMakeLists.txt

Pip

Aha!

add it here: set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

gotta go, sorry

cya

Icy Defiance

pretty sure it has to be after -lX11 though

Almo

-fuck man

that's the one you need

Almo

2:09 AM

@IcyDefiance you still debugging?

Icy Defiance

yeah but I need a break anyway. this is getting way too strange.

MickLH

@IcyDefiance Perfect timing, lets get to work

Almo

hahah

Icy Defiance

D:

lol what you got, Mick?

Almo

lol or hots?

Icy Defiance

2:10 AM

uhh, your choice, both sound good right now

MickLH

I'm just working on the usual stuff, so don't feel obligated lol

Almo

let's do hots then

shjorter games

Icy Defiance

aight

brb on windows then

Joe

2:58 AM

ooo new fancy gfycat

interesting

MLM

How can assign a the current class to a shorter variable name in C#? var self = MyLongNameClass; self.increment();

I want to access the static members without writing the long class name every time

Solved it! You can just do: using self = MyLongNameClass; at the top

Chris

cool, that's handy to know

Siddharth

4:49 AM

I need your help in following question

answers.unity3d.com/questions/929330/…

Icy Defiance

docs.unity3d.com/Manual/LoadingResourcesatRuntime.html

if none of that helps you, you might need to make your own fbx importer, or find someone else who already did that

emphasis on "might". I don't know all that much about unity.

Siddharth

okay

thanks for your suggestion

Icy Defiance

6:07 AM

so pretty

Chris

if (--windowCount == 0)

what is the -- ?

Icy Defiance

subtracts 1 from windowCount before doing the comparison

I probably should split that into two lines, but when I wrote that I was just trying to get things working

Chris

is it the same as windowCount-- ?

Icy Defiance

"windowCount-- == 0" would compare to 0 first, then decrement
"--windowCount == 0" decrements first, then compares to 0

"windowCount--;" by itself on a line would be the same as "--windowCount;"

and this confusion is why I should probably just split the thing into two separate statements, lol

Lasse

I miss linux :(

that thing was just made for programming

Chris

6:23 AM

@IcyDefiance ahhh k gotcha, thanks, never seen it like that before

Icy Defiance

@Lasse the Unity desktop finally got to a point where it doesn't crash every time I enable a second monitor, and I'm really liking it now. this is the first time Linux has actually run on my hardware without changing a grub command or diving into config files or any of that shit. it's actually "just working" and it's awesome.

Lasse

cool. if only the Unity desktop wasn't horrible to use in general I would be happy about that :P

Chris

I was using Ubuntu the other day and I tried to drag an icon from one folder to another. The drag crapped out half-way, was stuck with an icon image floating on my screen, impossible to clear, was even above my full-screen game, had to restart to get rid of it lol

Icy Defiance

dunno how Unity is horrible to use. seems fine to me. just needs keyboard shortcuts for moving windows around, but I can probably add them somehow.

even the web results in the search got changed so they don't hold up the other results while they load, so that's not annoying anymore, but I disabled them anyway because they're unnecessary

Chris

I was just about to say that Canonical just wants to insert their Amazon aff ID into your amazon url search results, but looks like they made that be an opt-in feature: networkworld.com/article/2226648/opensource-subnet/…

Lasse

6:31 AM

I haven't been using the latest versions in about two years, so I might be wrong about it

I need to try it out some time

Chris

I still prefer Ubuntu to the other distros I've tried. Xubuntu is my fav

Icy Defiance

yeah even in 14.04 unity was shit. I'm using 14.10 now and it's just miles better.

oh and it does have keyboard shortcuts for manipulating windows. it's ctrl+win+arrow instead of just win+arrow

well there goes my last complaint
