like they did with emplace_back in vectors

user4704

I dunno, I think that's a bad idea in general.

user4704

Just leads to the for-loop-scope-conformance switch.

user4704

Or people avoiding it anyway because it's not quite correctly standardized.

OMGtechy

for example, constexpr, I'd like to be able to have that bit of code compile at least, even if it doesn't apply the optimisations

Wardy

how do i tell unity to generate folder structure when it don't exist ?

MickLH

20:01

@OMGtechy #ifdef ...something... #define constexpr

Look ma, it's almost like a polyfill

Wardy

I'm generating the textures for my planets and saving them to disk but im using planet names as the parent folder and it bombs out if the folder aint there

OMGtechy

@MickLH I want ma constexpr D:

MickLH

You will sit here until you eat your #defines and you will like it mister.

Almo

@Wardy you should be able to access system.io and create the folder if it's not there

OMGtechy

@MickLH :(

Wardy

20:03

@Almo hmmm thats annoying

Almo

agreed

Veritas

hello everyone, what's up ?

MickLH

The other sky, if you're inside the earth.

Wardy

I thought that unity might have a more forgiving overload for saving stuff

@Veritas all the stuff that aint down I would guess

Veritas

eh..

OMGtechy

20:04

@Veritas is your name a pun on coveritas btw?

Veritas

No, not really.

What's coveritas?

OMGtechy

nvm :D

hello aha

MickLH

@Veritas It's proof that your google-fu is not super saiyan level.

Veritas

Not that many relevant results tbh.

OMGtechy

@MickLH it's over 9000

MickLH

20:07

@Veritas I'm 100% breaking your balls, notice I said "super saiyan"

Kevin van der Velden

Why would Veritas be a pun of anything? It's an existing word: en.wikipedia.org/wiki/Veritas

OMGtechy

@KevinvanderVelden because I hadn't heard of the word but had heard of coveritas :D

Icy Defiance

coveritas is when there are two veritases. one is the main veritas and one is the coveritas.

it's like a veritassistant

Kevin van der Velden

@OMGtechy well it means truth =p

MickLH

So then is a coveritas an alternate truth?

Kevin van der Velden

20:08

It's also the name of a goddess in roman mythology

OMGtechy

Coveritas is a piece of software

pretty sure it's been renamed / mostly forgotten now

Veritas

yea it appears to be called Vertizan now

Wardy

@MickLH or the opposite of the truth

MickLH

@Lasse What's that one picture you used to describe how Dwarf Fortress provides fun, versus the way other games provide fun.

I vaguely remember someone on a throne with a viciously satisfied look and discarded fun containers all around

Lokkij

@MickLH dwarffortresswiki.org/images/thumb/4/40/FunComic.png/…

Oops, it's a bit small

MickLH

20:23

yes, thank you

We're obviously not going to kiss, ever lol

Veritas

quick question - is it undefined to copy a storage buffer with a placement new created object as a swallow copy method?

MickLH

How do you do it?

Wardy

@MickLH thats cool lol

@Veritas whats a swallow copy method?

MickLH

I'd guess you're casting to void* eventually, @Veritas, which becomes UB if you do anything except cast it back to the original pointer.

Although in my experience, reinterperet_cast<> never does anything lol, so banging the pointer around after Works For Me(TM)

But I'd think, if placement new exists, there should be some well defined way to use it... I haven't come across the use case though. I'd love to see what you're doing.

Veritas

reinterpret_cast actually works for placement_new

ideone.com/1BOIl8

^

I am almost sure this is undefined

MickLH

20:38

lol, it looks super sketch

Wardy

wow i really need to be less cautious with cpu time

unity process ... 1% cpu

whilst generating an earth sized planet

ooo a spike to 3%

no wonder this crap takes so dam long

MickLH

@Veritas Well the reinterperet_cast and the aligned storage are the only things that look possibly weird to me. And that's only because I'm too lazy to find relevant language in the spec :P

Although it makes me think you're doing something weird somewhere if you need this.

Veritas

not mine

MickLH

Ah ha! So you're working with weird people

You weird thing doing weirdo

Veritas

the reinterpret cast in this case works because the dynamic type is the same as the one that we cast to

but I am not sure if simply swapping the storages is a valid way to swap the objects

it should work in most cases but it smells like undefined behaviour

MickLH

20:48

Well I'm still too lazy for the spec

JohnPoison

@Veritas you may ask it in c++ lounge =)

Veritas

will do

MickLH

But with logic, you can see that pointers to internal members can be destroyed

JohnPoison

never used a storage, what is it for?

MickLH

I would guess it's intended for explicitly controlling alignment of individual fields within a class

Veritas

20:51

it's intended for use with placement new

MickLH

@Veritas 1. lol why did you ask that question here but not there. 2. did you post a question on stack overflow first? 3. you might get better results on C++ lounge if you've posted a question first :P

Veritas

1. Wasn't even aware of the Lounge and it was really intended a very fast and quick question.

MickLH

So far, writing a question has always been faster on Lounge<C++> for me :P

I mean, writing a question on SO, and then going to chat.

Veritas

@Wardy how is the generator going?

MickLH

The other way around, no matter how trivial, has resulted in the RTFM'ing and no-question complaining taking longer than actually writing the question.

Wardy

20:54

its not really @Veritas

I haven't done anything with it for a while ... been playing with windows 10 stuff

and this stupid ass uv mapping issue is pissing me off

Almo

the Lounge is seriously misnamed

that word somehow implies a relaxed atmosphere

JohnPoison

@Almo oh yeah

Wardy

I went to crazy lengths to build a mesh gen that used the same params as the noise gen but for some reason my textures aren't being put on the right parts of the planet meshes

Veritas

well that sucks

MickLH

I want to go ask about the implications of using int x = 1 + 1; instead of using int x = 2; on C++ lounge, and see how many hours it takes before they say it's the same

Almo

20:57

hahaha

MickLH

and see how many years it takes to realize that 1 + 1 was the better option because it was probably magic number that makes sense + other magic number that makes sense

Almo

I'm sure you can find a question to mess them up for hours

MickLH

I used to hate programmers

But then I found the C++ lounge and realize it really is just my choice of language

Almo

hahaha

Wardy

@MickLH It's not just me then

Almo

20:59

if those two statements were on the same line I'd star it

Pip

@Wardy I guess it takes the mind of an ignorant ass who comprehends problems easily to answer this kind of question.

A: How to float object up and down in space with Unity?

You have a pretty simple solution. What your problem here is that you are not preserving the original y position. Essentially, you need to store the original y position in a variable, that would look like this: (Don't forget to set the variable in the Start() function.) Vector2 floatY; float ori...

Wardy

I thought the same thing a while back

MickLH

@Almo Noted, lol I'll try to buffer a couple messages and evaluate whether or not there is a benefit to starrability to be had by grouping (or maybe even ungrouping)

Wardy

@Pip lol so I gave you the answer as a comment ... he then improved the question whilst you wrote the code up for it

nice

Pip

lol yeah

Lol he has 3 famous questions on SO

stackoverflow.com/help/badges/28/famous-question?userid=1246832

JohnPoison

21:04

So does C++ programmer mean hater?

Pip

lolno

MickLH

but close

C++ lover means hater

Veritas

:<

Pip

C++ Programmer =/= hater == C++ lover

Almo

@MickLH :D

JohnPoison

21:04

lol

Pip

lol

JohnPoison

I love c++ but I'm not a hater

Almo

pip wtf is =/=. Come on man, use a real operator: !=

MickLH

@Almo He tricked you

Now you made the logic error, it was just syntax before

Almo

:)

MickLH

21:05

lol array index error

Icy Defiance

@JohnPoison after attempting to create a new C++ development environment in windows that wasn't visual studio for the last 2 days, I must say, I hate C++

MickLH

I have to go do hygiene and life-sustenance bullshit now, be back in a while

JohnPoison

@IcyDefiance lol, I hated C++ when I worked on porting ios game to android

that was a hell

Almo

you didn't do Java?

Veritas

C++ is probably my favorite non-scrippting language

JohnPoison

21:07

game was on C++, so we used NDK

Almo

ah ok

I do all my iOS stuff in Objective-C

Pip

@Almo lol

JohnPoison

but android is an epic shit

Almo

hahaha

Pip

yes it is, for programming at least

Almo

21:08

I've just read how it works... each app is a user in a linux system

Pip

it's a decent os IMO

Almo

its interfacing is shit

I can't really comment on the OS

JohnPoison

it's a non-standartized shit

Icy Defiance

developing for android really isn't that bad...until you get an error

Pip

(any error)

Almo

21:09

hahaha

JohnPoison

if you look at it as a user, maybe it's not bad. But If you look as a programmer...

Icy Defiance

android errors are as cryptic as linker errors and half the time they're not even kind enough to give a line number

Almo

as a user with no knowledge of what good interfacing is, maybe.

one example: scrollable list when you hit the bottom.

JohnPoison

debugging c++ under android is a torture

Almo

iOS: resistance starts. it still moves as you move your finger, but less. you get the idea you're at the bottom

droid: stops cold. is it still getting my input? scroll up down, stops again, nope, that's the end of the content.

the interface is riddled with these kinds of things

Icy Defiance

21:11

nah android has something like the resistance thing. I'm not sure when it was added though, and I forget whether it happens while dragging or just when you flick and it hits the bottom.

don't have my phone on me to try it

WP7 didn't have it at first, but it was added real fast

Almo

it's some blue thing that shows up

hard to see

unless that's just in the version of droid I had

Icy Defiance

blue thing...yeah I know my phone doesn't have that.

Almo

well I'm heading out for today. talk later guys. :) I might be in for LoL tonight, Icy.

JohnPoison

@Almo I loved ios. But now it feels like ios is going different way than before, after Jobs passed away. It became less polished and more buggy

Pip

cya Almo

Almo

21:15

@JohnPoison Not sure about that, but I'm still on iOS 7. My wife has two 8 devices.

(iPhone 4, so I can't get 8)

bye pip

JohnPoison

bye

I also have to go. Good night

Pip

night

OMG it feels so good to finally be able to cast a decent spell with my retarded troll.

Though he's chewing through my fruit supplies like crazy now.

Q: Unity simple map generation

I am trying to generate simple map like this. Everything works as i want, but i am new to programing so my question would be, is it a good way to do something like this? And if not maybe someone would explain me where and why it is bad to do something like this. And how bad is it on performance. ...

c# unity3d

just spat out a 2d map gen and mesh gen from my head

I bet its broken though

MickLH

hahahahaha

> i will be reading your code and learning what it does for next week :DD – user2351722 6 secs ago

Wardy

was it really that complex ?

its likely wrong

Pip

@MickLH lol
