@Almo the current ios version not building?

Almo

I haven't tried, just going to get the latest one to be sure

it bitches about stuff when going back a version

(or two in this case)

Jon

should be fine though

i had issues with one of the sounds.. click9

Almo

Asset '/Applications/Unity5.1.4/Unity.app/Contents/UnityExtensions/Unity/GUISystem/Edi‌tor/UnityEditor.UI.dll' is in timestamps but is not known in guidmapper...

stuff like that

i'll see what it does

Jon

NH caucus

reddit.com/live/wealjzue5de5

Sanders takes NH !

woot woot

Almo

seems to work

still says "1.13" on the about page

Jon

12:10 AM

really?

Almo

yeah

Jon

checking

yeah,

i'll put the version in line with the android one

weird.

i commit 1.22

Total Votes: Sanders 17, Clinton 9

He won by a landslide

60.7%

Icy Defiance

those are just exit polls, right? it's not done yet in a few areas, and they won't report official results until then.

Jon

not done

but looking damn good

Icy Defiance

yeah 60.7% is a pretty good margin.

Jon

12:17 AM

shitload of data to come

pretty exciting

Almo

that screenshot tool kicks ass man

$7

WORTH

Jon

hehe

Shen Ruki

The Mac screenshot

Almo

@jon you want me to submit this build?

Jon

the latest you just got?

Almo

12:24 AM

yeah

Jon

yeah

Almo

with the version update

ok

what version is it?

Jon

can i give you the free version?

1.22

Almo

not much point yet

have to set up a new app in itunesconnect

Almo

1:04 AM

@jon can't submit yet, cause I can't get one of the screen shot sizes set up

have support mail out to apple

Jon

Ok

Almo

1:47 AM

@jon default from plugin was wrong

750x1134 instead of 750x1334

@jon I need the "App Description" text for the submission

and do you want the screenshots in the Git depot?

Q: Matrix column switching

I'm currently working in the math library for a game framework that I'm writing and am working to improve some functionality that was affected during a refactor. Formerly, my Matrix4.SwapColumns(int, int) function looked like this: /// Documentation public void SwapCols(int i, int j) { for(...

If anyone has any input, I'd be glad to hear it!

Almo

2:30 AM

@jon 1.22 up on testflight

@jon submitted for review. Can add description later.

Can also cancel and submit 1.23 if you want

Aidan Mueller

...

so how 'bout them singletons?

;P

Almo

I use them

Aidan Mueller

I'm just playing with my lighter.

Underage alcohol consumption is legal in some states for "educational purposes". The question is, what qualifies as "educational" :D

Icy Defiance

3:25 AM

@Pip for my C++ framework I just added the [] operator to vec4. it's still O(1) there because it just returned "reinterpret_cast<float*>(this) + i", but I don't think you can do that in C#. at least not easily...

Almo

icy!

matchhistory.na.leagueoflegends.com/en/#match-details/NA1/…

Got a pentakill with cait

:)

Pip

@IcyDefiance yeah, my Vec4 has that

but remember properties are methods

Almo

was 1/7 or 1/9 at one point in that game. came back started dominating :)

Icy Defiance

and a comeback win too. very nice.

Pip

so if you modify the vec4 you get out of mat4[], it does nothing (except a compile error since it's immutable)

Icy Defiance

3:27 AM

oh yeah 'cuz it returns a copy of the vec4. good point.

Aidan Mueller

@IcyDefiance You're writing a linear algebra library?

Icy Defiance

I just wrote the basics of one for my framework because glm's design made me angry

Aidan Mueller

What's wrong with GLM?

Icy Defiance

it works fine. I just don't like the structure of it. too many free functions that I think should be class members, or at least static class members.

being free functions, it's hard to find which one to use without google. with class members I can type in the class name and use intellisense to scroll through a much smaller number of functions to find what I want.

Aidan Mueller

I can see how you might want that. I just don't use auto completion, so that's no issue.

Icy Defiance

3:33 AM

it's all pretty simple to implement myself anyway. there's just a lot to it, so my implementation is missing a lot of things that I just haven't needed yet.

Aidan Mueller

It's actually not that bad. You might think "but how would you do anything without googling everything". I find that your brain is like "Oh, the IDE won't remind me every time? OK. I guess I'll just keep documentation in my head".

@IcyDefiance Why don't you just fork glm?

Icy Defiance

you're right, but it still feels bad, and since it's just a hobby project anyway I can value that feeling pretty highly

Aidan Mueller

Personally, I just feel like anything I make will not be as good as GLM.

Plus GLM is designed to feel like GLSL, which I use anyway.

Icy Defiance

well the math is simple enough that it's hard to be either worse or better than glm, unless you somehow break some compiler optimizations. it's mostly all structure.

refactoring glm to the structure I want would probably be more work than just typing it out myself

Aidan Mueller

You know what is nice about C++ that Java could do? It doesn't make you type the access every time. In java you have to either type private or public every time you make a new method. In C++, you just make one "everything that follows is either public or private" statement and you're good. Keeps public stuff grouped together too.

Icy Defiance

3:43 AM

all that being said...I have to wonder why @Pip is making the same library for C# instead of using OpenTK's. I want to ask him some of the same questions you're asking me.

OpenTK's math library feels way nicer than glm imo

MickLH

4:02 AM

glm is amazing and does all the things!

opentk probably eats babies

Icy Defiance

4:20 AM

maybe but so do atheists and metalheads and they're pretty cool

Aidan Mueller

I need some help from your side regarding unity problem

following post represent my complete problem so please go through it

answers.unity3d.com/questions/1136854/…

in this I also tried with this kind of code but can't able to get success in this

void Update ()
{

// If there are two touches on the device...
if (Input.touchCount == 1 && GameManager.Instance.IsGameStart) {

// Store currnet touch.
Touch touch = Input.GetTouch (0);

// transform.RotateAround (transform.position, Vector3.up, -touch.deltaPosition.x Time.deltaTime 15f);
// transform.RotateAround (transform.position, Vector3.right, touch.deltaPosition.y Time.deltaTime 15f);

// transform.Rotate (Vector3.up, -touch.deltaPosition.x Time.deltaTime 10f, Space.World);
// transform.Rotate (Vector3.right, touch.deltaPosition.y Time.deltaTime 5f, Space.World);

some Folk

this android studio thingy is slower than my windows 98 machine

i mean, if i had one >.>

NDraskovic

@Siddharth is the rigidbody rotating wrong, or it doesn't move at all?

Siddharth

it can't able to detect y direction rotation, in above code z direction rotation is fixed

I want rotation to be done in x and y both direction

even I have fixed rigidbody z rotation from inspector

if I test through commenting single line then it independently working correctly

I am talking about these 2 lines

myRigidbody.MoveRotation (myRigidbody.rotation Quaternion.Euler (Vector3.right touch.deltaPosition.y Time.deltaTime 5f));
myRigidbody.MoveRotation (myRigidbody.rotation Quaternion.Euler (Vector3.up -touch.deltaPosition.x Time.deltaTime 10f));

one by one these lines are running correctly

but together first line can't able to get effect

please if you have any idea then help me

NDraskovic

what was wrong with these two lines:
// transform.RotateAround (transform.position, Vector3.up, -touch.deltaPosition.x Time.deltaTime 15f);
// transform.RotateAround (transform.position, Vector3.right, touch.deltaPosition.y Time.deltaTime 15f);

Siddharth

these 2 lines can't able to stop z rotation

please go through this as well

NDraskovic

8:53 AM

have you tried adding a third line, that would just keep the z rotation to zero, something like:
transform.RotateAround (transform.position, Vector3.forward,0); ?

NDraskovic

9:11 AM

Hey guys, I have a question about saving game data - do you use XML files or something else (I'm talking about slightly complex data like the coordinates and type of buildings/units, not just simple numeric or string values)

this is in the context of saving level info and player progress

user92578

10:11 AM

@NDraskovic I use XML and I like it, but everyone else will suggest you use JSON

user92578

I'm using C++, so my systems are not very "clean", meaning other languages (like C#) might be better at this stuff.

NDraskovic

10:42 AM

@Tyyppi_77 yeah, I'm trying to decide between those two (we are working with Unity/C#) - does the platform play a role here? We intend to publish the game for PC and mobile platforms, so I don't know how each of those platforms would react to XML/JSON. Also, JSON is stored (in the case of mobiles) in the internal memory of the device, and we might want to use the generated files for some other purposes (actually the game will use those files, and might have to transfer them between devices)

DarkHyudrA

both XML and JSON are just files, they have no special behavior or magic behind them

the difference is that JSON is faster on most cases ans it's use is more widely spread since it became the new web standard for data sending and receiveing

---note: the part about faster is what the internet says, never actually made a test

NDraskovic

I know from web-development that it has less overhead than XML, it's faster because it is usually smaller than XML files

Fuzzy Logic

@Siddharth you need to save the Z-rotation before you update, then restore it afterward if you want it to be fixed rotation. That's the simple way anyhow.

NDraskovic

But, what I want to know is, how will my teammates who create the level or level configuration be able to send me the file I need to put into Unity

Fuzzy Logic

email?

DarkHyudrA

10:48 AM

are going to make a level editor, so the player can load it in runtime?

NDraskovic

I want to create a simple level editor to enable my teammates (who are not programmers) to create levels in Unity's editor, and send me the resulting file so I can use it in level creation. I also believe that the same file, or a copy of that file can be used to save/load players progress in the game

DarkHyudrA

for the level editor... there's no magic way, you need to read it, have a blank scene and start to clone objects and setting their properties the values that are on the file

Fuzzy Logic

Use XML or JSON, like @DarkHyudrA suggested, or invent your own if you want. does it need to be editable in a text editor?

NDraskovic

@FuzzyLogic on the part of the player, no.
@DarkHyudrA yeah, I mean what I think should work is - store data about level elements in XML/JSON file, load it on scene load, parse trough it and create GameObjects of the type specified on the location specified in the file

I'm just collecting info about the possibilities, so that I can do it in as optimal way I can

DarkHyudrA

yup, this is the only way really
that's actually what Ogmo Editor and Tiled actually does (except for the loading part ofc, they just generate the XML for you in organized manner)

if you can teach your non programmers friends how to use Tiled, and you create a set of default values so that they know what they can do, it can be a good solution

I don't recommend Ogmo Editor though, very buggy

NDraskovic

11:06 AM

Well I think I can create a separate Unity project where they can visually just create the level (it is 2D so it just a matter of drag and drop prefabs) and then click a button that will generate a file. I don't think using 3rd party software is necessary because the structure (or the class that represents it) is not too complicated

Fuzzy Logic

Unity already stores the level in a meta file. Save state is another matter

NDraskovic

@FuzzyLogic yeah, but if I use the meta file, I have to create a special scene for each level, but if I generate them from file I might be able to use the same basic scene and just instantiate the stuff I need

DarkHyudrA

from my experience, Tiled will serve you well then, but if you want to make sure that your friends aren't going to do mistakes in the properties names, then you will need to write some app on your own

NDraskovic

do you know what Tiled gives as result - what type of file?

DarkHyudrA

it's both XML and JSON IIRC, let me see the github

Fuzzy Logic

11:11 AM

tiled uses TMX format, which is XML

NDraskovic

OK, thanks for the info, I'll do some more research about the pros and con's of using either type, but this has been helpful. Tanks guys

DarkHyudrA

seens that JSON is supported since a few months ago aswell as the TMX(XML) file

github.com/bjorn/tiled/wiki/JSON-Map-Format

Fuzzy Logic

fyi, Unity directly supports JSON format

XML can be used as well but you need to use C# system libraries

DarkHyudrA

@FuzzyLogic you mean, a one-function to load the JSON?

NDraskovic

there is a JsonUtilities class in unity to save into / load from JSON files in unity

Fuzzy Logic

11:15 AM

I haven't played with it myself, so I couldn't say but I would guess it's simpler to deal with than XML

NDraskovic

but it only saves a string and gets string and fills the object of specified type, that's about it

Fuzzy Logic

that's all that json is

NDraskovic

well, you got me thinking right now (and that's usually a bad sign :D ) - we are in the prototype phase of development, I don't think it would cost to actually try both approaches and just measure how long it takes for each of them to generate the same level

Fuzzy Logic

you could do the same as JSON (without being text-editable) by making your save state class serializable and just dumping it to file

the time difference will be moot

the real difference will be how to have to handle the formats

NDraskovic

What do you mean?

Fuzzy Logic

11:20 AM

XML is generally more freeform, so will likely require more effort to manage

JSON is an object notation so it is literally a dump of your object in javascript object notation

NDraskovic

and I would think that JSON will require less space to store

Fuzzy Logic

yes, but that's actually pretty trivial unless you are storing a LOT of data

NDraskovic

can JSON store complex data types? like having an object inside an object?

DarkHyudrA

JSON can handle even lists

Fuzzy Logic

yes, it will handle all JS types

NDraskovic

11:24 AM

ok

DarkHyudrA

the only real problem is that JSON is a bit less human readable

Fuzzy Logic

it's also less flexible

NDraskovic

what do you mean by "less flexible"?

user92578

JSON is missing attributes for one

user92578

Atleast it's a little different in that matter

Fuzzy Logic

11:29 AM

because JSON is an object notation, if you modify the class, then your existing json files may break

user92578

Not necessarily

Fuzzy Logic

it's easier to provide forward compatability with XML

user92578

JSON can be just data that you parse by hand

Fuzzy Logic

yes, but that kinda defeats the purpose

you could just make an INI format too

user92578

Well not really, you can also use XML as an object notation

NDraskovic

11:31 AM

yeah, I mean my plan is just to store the objects that are/were on the screen and their basic parameters, just that those objects might hold one other object (again it would have only a few parameters)

and then when the scene is loading, read from the file and set the parameters of the GameObject depending on the data in the file

user92578

Yeah my current plan is to not save in-level progress, only the level name, as my levels are quite short

DarkHyudrA

saving in-level progress is a bit more complicated, you would need to make unique IDs to some objects, so that you remember what you have interacted

NDraskovic

we are working on a city-management type of game, so I need to remember which building was placed where

user92578

Ah yeah, that should be manageable

user92578

Maybe you could even re-use the level file (format)?

NDraskovic

11:33 AM

yup that's the plan

DarkHyudrA

for that kind of game seens a good plan

since the level itself is the game

NDraskovic

while we are on the subject, do you know how many GameObjects can Unity handle (lets say on devices from the Galaxy S4 generation) without serious performance slowdown?

Fuzzy Logic

how do you plan to perform saves? at checkpoints or realtime?

NDraskovic

haven't thought about it, but atm probably just on the game exit

Fuzzy Logic

ok, just curious if saving so much data at once would impact the game. I'd suggest a Db format if so

the number of gameobjects that unity can handle is mainly limited by hardware resources

if your game is optimized (ie. if most objects are dormant), you could have 10's of thousands

in general you will find it slowing down after a few thousand

main thing is that every gameobject runs some type of updates/checks every frame

NDraskovic

11:43 AM

I think that most of them are just going to be showing animations, only few types will actually do some calculations (and again very simple ones)

but in any case, I don't expect more than hundred, maybe couple of hundred objets

objects*

Fuzzy Logic

(press up in the edit box to edit your previous message)

NDraskovic

hahah didn't know that one :D

PearsonArtPhoto

1:02 PM

Turns out the seems were a result of using linear interpolation, not the vastly better cosine interpolation.

Huge difference:-)

Still not perfect, but...

user92578

yup

PearsonArtPhoto

Much better final product:-) I can barely tell how it was tiled.

DarkHyudrA

added some noise?

PearsonArtPhoto

Well, I started out with something similar to the last. I saw something that looked like seams, that I was trying to study, so I simplified.

And the seams were very visible in the simplified plots. I fixed the seams in the simplified plots, and returned to the final result.

17 hours ago, by PearsonArtPhoto

I don't think I set the parameters quite the same, but...

It seems to me pretty clear that the version I have now doesn't have the seams, and seems a bit more realistic overall, vs what I had yesterday.

Amazon to release its game engine, for completely free. kotaku.com/…

DarkHyudrA

1:19 PM

another guy already showed that yesterday

can't remember who though

I even remember Josh saying that it'll fail since it's a old fork of... CryEngine? Or was it unreal? can't remeber, would need to check the transcript

PearsonArtPhoto

CryEngine.

Maybe that's why CryEngine was being discussed...

DarkHyudrA

yup

PearsonArtPhoto

Apparently there is a zombie clause in it's terms of service. kotaku.com/amazons-new-engine-has-a-zombie-clause-1758126278

DarkHyudrA

lol

I would like to understand why softwares made on USA need those terms saying that the software must not be used to make military tings, WMD or nuclear things

I was very wtf'd the first time I read the first terms of Oracle

Fuzzy Logic

hehe, if someone is going to use some software to create a WMD, I doubt they would be concerned about breaching a ToS. They gonna get sued?

DarkHyudrA

1:33 PM

would be fun to see someting like
Foo Bar arrested for:
-crafting a WMD
-using illegal software to develop the WMD

PearsonArtPhoto

It's not that you can't use the software for such uses, just that they are warning against it.

And trying to say, you build a life critical system on our game engine and the engine crashed, it isn't our fault.

Fuzzy Logic

what they are doing is CYA

so nobody can say they didn't make an effort to deter such uses. it's stupid but that's n.american justice system

just like disclaimers on unrealistic commercials

PearsonArtPhoto

Although if there is a zombie apocalypse, then you can use the engine and expect that it will work, and sue Amazon if it doesn't.

DarkHyudrA

IDK how it's written on USA, but every advertising on my country has something like "merely illustrative images"

Fuzzy Logic

yeah, pretty much the same. disclaim everything to pre-empt any posibility of civil suit

in reality the people filing petty suits should be getting charged

I always think of the lawsuit against Pepsi when they had one of their contests a long time ago and jokingly advertised that you could win a Harrier jet. Some guy saved up enough bottle tops to earn it but Pepsi couldn't deliver

DarkHyudrA

1:49 PM

was googling it (I've never heard of it), and it says that actually the guy bought "the remaining 6 milion points" so he could ask for the harrier

Fuzzy Logic

yea, he lost as well

I don't know if he was even reimbursed. (he shouldn't have been)

PearsonArtPhoto

If you jokingly advertise something like that, it had better be either impossible, or clearly not in some rules or something.

Fuzzy Logic

well it is impossible. the harrier would have to be refitted at least and I doubt a civilian could even own one

PearsonArtPhoto

Right.

Clearly for the cost of $700,000 it should have been clear it would be impossible...

Fuzzy Logic

nevermind that, if I were spending 700k, I'd be getting my facts straight first

PearsonArtPhoto

1:56 PM

Seriously...

Fuzzy Logic

the guy was clearly trying to manipulate the system

that should be criminal

PearsonArtPhoto

Or a bit crazy.

DarkHyudrA

I don't know a person that is that crazy with 700k on their bank acount

Fuzzy Logic

crazy people with 700k probably don't have 700k for very long though

DarkHyudrA

yup

a guy that won at the lottery a few millions lost it all on a single year

Fuzzy Logic

2:00 PM

lots of lotto winners lose it fast

I know a guy who won 1mil and lost it in about a year, after buying a house that he couldn't afford to maintain and investing in a bunch of race horses he never saw

DarkHyudrA

that's why it's called gambling and not investment

Fuzzy Logic

naw, he bought into ownership of the horses, not betting on races

DarkHyudrA

oh

that sounds even more stupid

Fuzzy Logic

non-existent horses

'morning ^^

Shotgun Ninja

Good morning, good moooooor-ning ding

Pip

3:17 PM

@IcyDefiance OpenTK has been abandoned. There's no one who can merge PRs on github now, let alone commit

Shotgun Ninja

@Pip clone it, maintain it, call it OpenOpenTK

Pip

@IcyDefiance Also my math library is basically finished

@ShotgunNinja I extremely dislike some general design decisions that they've made and I'm unfamiliar with most of the code

Flare is good for me because it's super simple, at least at the moment, I know my way around it, and it works all of the time :P

And I know that I can maintain it

Alexandre Vaillancourt

3:48 PM

What would be a good use-case for a shared_ptr?

user92578

Which reminds me, I should learn about smart pointers

Alexandre Vaillancourt

;)

Alexandre Vaillancourt

4:06 PM

You could probably right away change all of your raw pointers by unique_ptr

user92578

Currently I use raw pointers everywhere

user92578

Even when definitely not necessary

user92578

That's something I might want to go around and fix

user92578

And I'm thinking it might not be impossible

Alexandre Vaillancourt

Do you have memory leaks? :P

user92578

4:07 PM

Probably... :)

user92578

But yeah I should really start transitioning to references when a pointer is not absolutely necessary

user92578

However I'm thinking that I'll break too much while doing that

Alexandre Vaillancourt

Do you have a way to "reset" the game? If so, just looking at the task manager (at the memory the game uses) and resetting the game a couple of times should give you a hint!

user92578

I can reset a level and so on

user92578

Also reload a level in the level editor

user92578

4:10 PM

Hmm, nothing major atleast it seems

user92578

Anyways those references would just probably be a lot more manageable

user92578

IDK

Alexandre Vaillancourt

Well, there is nothing wrong passing a pointer around, it's just the global phiolospy of it: who owns it, who's responsible for deleting it?

user92578

Yeah I think mainly the problem for me is not the actual complicated designs, but simply the fact of remembering to write that delete line

Alexandre Vaillancourt

Yeah!

user92578

4:15 PM

I'm not that sure how these things are actually supposed to be

Alexandre Vaillancourt

What things?

user92578

Game system things

user92578

Like where pointers in general are used, and where avoided

user92578

Sometimes I have these architecture breakdowns where I get depressed about everything I've written

PearsonArtPhoto

Look at the bright side. You must be getting better to notice all of the depressing architecture you worked on previously.

user92578

4:19 PM

Yeah kinda. And in general I don't think my game architectures are that bad, and some of them are quite good/clever

PearsonArtPhoto

I don't have enough to judge my game architectures, or any kind of architectures...

My app architecture is getting better I suppose.

DarkHyudrA

well, if it works and fits with everything else, then you're doing a good job

PearsonArtPhoto

I judge an architecture on 2 things I suppose. How easy is it to add a feature, and how well can I remember it 6 months later.

user92578

I should probably spend some time soonish and come up with a basic "production plan"

user92578

so much to do

user92578

4:23 PM

luckily the game's not nearly done yet

user92578

but it will be one day

Alexandre Vaillancourt

Yeah, lot's of stuff is done like this: think-do-inspect-think-improve-inspect-think-improve (etc)

PearsonArtPhoto

Oh, and how long before I find a problem that I have to nearly completely rewrite some basic logic module

I guess by those metrics I am definitely getting better, but judging "clever" is difficult.

Almo

			for(int i = count - 1; i >= 0; i++)

hahahah

user92578

lol

Almo

4:36 PM

(my mistake)

WTF is it doing this twice?

when Unity hits an exception, it exits the function and keeps plowing on

so it didn't just keep going

user92578

weird

PearsonArtPhoto

For count=0?

Almo

i--

sposed to loop backward

DarkHyudrA

he needs to either do i-- or i <= 0, otherwise infinite loop

I think that every programmer has made that mistake

Almo

i'm sure :)

PearsonArtPhoto

4:41 PM

I might have, but for some reason I'm blotting it out...

I rarely count backwards, so...

user4704

I implemented a reverse iterator last night to count some stuff backwards.

user4704

It reminded me how much I hate C++'s iterator model as far as custom implementations go.

user4704

It's very difficult to avoid all the tedious boilerplate.

Alexandre Vaillancourt

I'm glad I never had to do this :P

user4704

Look at this mess: github.com/jpetrie/quip/blob/master/Source/Core/…

user4704

4:45 PM

github.com/jpetrie/quip/blob/master/Source/Core/… sadness

user92578

wow

user4704

There are a few ways to reduce that with some clever template tricks, which I'll probably add in this evening.

user4704

But if you're doing things the straightforward way, that's all the basic boilerplate you need. I guess you can drop one or two of the operators, technically. It is a tricky system to extend.

Alexandre Vaillancourt

That's a lot to add

user4704

Mostly copy-paste, which is the worst.

The fundamental differences between the four types come down to ++ versus -- of an index and the const on the return value of operator* and like.

user4704

The latter one is the real wrench in the machinery.

user4704

Most of the other stuff you can encapsulate through, e.g., having a templated iterator<T> that works in terms of (custom) enumerator<U> interface; the enumerator just implements ==, operator* and next()/prior()

user4704

And then template metamagic in Iterator<T> via enable_if and type_traits invoke the Enumerator<U> interface accordingly.

Or you drag in tons of Boost for boost.org/doc/libs/1_40_0/libs/iterator/doc/index.html

Isn't that version of boost old and a lot of it has been added to c++ 11/14?

No, it's not old; Boost is still actively developed.

user4704

Parts of Boost were included, slightly modified, into the standard.

user4704

But quite a lot has not been.

user4704

The iterator stuff is in a TR.

user4704

I haven't actually used Boost in years, it's a pretty annoying dependency to deal with and I generally don't need it.

Alexandre Vaillancourt

Yeah, I was only referring to 1.40 :)

user4704

4:56 PM

Oh, yeah.

user4704

It was the link that Google gave me for "boost iterator library" shrug

user4704

1.60 or some such is the current I think; didn't even notice.

Alexandre Vaillancourt

Their listener pattern was Ok, so we used it, but now I have implemented something on our own that does the same thing.

It's nice when you don't want to re-code something, but yeah, the code looks as complex and not fun to read than what's in the std::...

Hello

user4704

Eh, reading the standard library is pretty straightforward

To get started, do somethign with your syntax highlighting patterns to desaturate the pattern __.*

user4704

it makes things much easier.
