@sn0k3 Is there any reason you need it in c++?

sn0k3

@AlexandreVaillancourt just decided to do it in C++

Alexandre Vaillancourt

Ok! There is also WXwidgets that is in c++.

sn0k3

ooooooh yeah!

Alexandre Vaillancourt

Code looks like MFC, but it's portable.

sn0k3

Code::blocks got that editor

what is mfc

Jon

2:02 PM

microsoft foundation

user92578

microsoft foundation class library

Jon

oldschool

Alexandre Vaillancourt

Microsoft Foundation Classes

sn0k3

:D

I'm not sure what is actually that

and is wx still updated frequently?

user92578

it's native GUI in Windows that's awful to implement

Alexandre Vaillancourt

2:03 PM

If you don't care about portability and it's Windows only, you could take a look at that..

@sn0k3 Not that much from what I gather..

Jon

i would recommend not using mfc

unless you live in a world where eveyrone is using windows 98

Alexandre Vaillancourt

^ This :)

Almo

@Jon if anyone wants to test an iOS version, I can get one out on testflight

user92578

I would probably recommend not using C++ for this, but if you really want to, I'd probably go for Qt

Almo

Important note: "QT" is pronounced "cute"

Jon

2:04 PM

@Almo alright then standby for the request

Alexandre Vaillancourt

I think what could work is have you UI in c#, but your render window in c++ :P not sure how it works, though :P

Jon

and i want you to sign a NDA agreement

lol

Alexandre Vaillancourt

(I know you asked not about c# ;P)

Almo

I would be happy to sign the same agreement we did for picross

Jon

Yeah, this source code is quite more intensive

Almo

2:05 PM

which included the level work belonging to you

Jon

and I don't want to have it leak

Almo

Yeah, makes sense to me :)

Jon

is my main concern

you ever make assets in unity... then update them?

like.. very late in development?

Holy fuck man...

Some of the assets I used lost their link for some reason

sn0k3

Guys

Jon

Others, took the default properties over the ones that were set

Fucked up a bunch of my levels

sn0k3

2:08 PM

which was one of the most famous indie space games?

Jon

you are making a space game?

sn0k3

no

why?

Alexandre Vaillancourt

Asteroid?

Jon

Omega Race

Almo

@Jon :(

Jon

2:09 PM

Its fine I fixed it up... just wondering how you avoid this?

Almo

@sn0k3 FTL

sn0k3

@Almo what?

Jon

seems like updating assets is dangerous if you ask me

Almo

@Jon I haven't run into this

user92578

KSP?

Alexandre Vaillancourt

2:09 PM

@sn0k3 Elite?

@sn0k3 Solar wind?

Jon

its a stupid question, lol

DH.

FTL is pretty famous, truth

Almo

ftlgame.com

sn0k3

It was under development, someone sent me a link for that game here months ago ( around 10 months )

Almo

FTL is good shit.

Jon

2:10 PM

gargantuous space battles

Almo

gratuitous

Jon

whatever

lol

Almo

GSB was really fun

Jon

point is, there are tons of them

I even made one

Almo

I didn't like GTB... didn't play it, but wasn't interested in it being a tower defense :(

Alexandre Vaillancourt

2:11 PM

@sn0k3 You try to identify the game?

Almo

A Gratuitous Space Battles fight

►

Almo vs Shrooomed GSB battle

►

Two GSB games I played.

PARTICLES!

sn0k3

Aha, well it isnt that

Alexandre Vaillancourt

@sn0k3 en.wikipedia.org/wiki/Elite%3A_Dangerous

Almo

Your question was "which was one of the most famous indie space games?"

sn0k3

someone said that the budget that the creators were spent on doing it was around million

Almo

2:12 PM

so we're answering that question

clarify your question if you're not looking for a list of indie space games

sn0k3

elitedangerous.com

yes

I think it was that, ty :)

Alexandre Vaillancourt

:)

Jon

way to go man

you solved the conundrum

sn0k3

I've wondered..Ty guys :)

user92578

Oh man, I should not be allowed to mark variables unsigned

Jon

2:15 PM

cuz i'm a wonderer.. yeah im' a wonderer.. .i wonder out loud out loud out loud

user92578

m_FirstChildInView--;
m_FirstChildInView = std::max(m_FirstChildInView, 0);

user92578

Just casually doing that on an unsigned value

user92578

Why unsigned + signed = unsigned?

Jon

why float + int = float?

user92578

because float is the more accurate one, that actually makes sense

Alexandre Vaillancourt

2:18 PM

@Tyyppi_77 You should never use unsigned, unless you need to use bitfields. That's what c++ gurus say :)

Jon

unsigned provides larger container

user92578

Yeah I'm starting to see that, it's just that I get warnings when comparing to std::container::size() and stuff

Alexandre Vaillancourt

@Jon if you need that, use a int_64 instead...

user92578

But like (unsigned)10 + (-10000) = something_really_weird

Alexandre Vaillancourt

@Tyyppi_77 yeah, and the c++ gurus said they're sorry for that :)

user92578

2:19 PM

aight, seems legit

Jon

the C++ gurus ^

Martin Sojka

Can't be true. I see way too few beards.

MickLH

@Jon adderall is amphetamine

Alexandre Vaillancourt

@Tyyppi_77 @Jon I found the video (two moments where they talk about it)

Interactive Panel: Ask Us Anything

►

Interactive Panel: Ask Us Anything

MickLH

2:35 PM

@AlexandreVaillancourt that's incomplete advice

Alexandre Vaillancourt

What is?

MickLH

size_t is unsigned and you'll be recommended to use that for sizes

Sie

How to make people hate you and your "movement" 101: breitbart.com/tech/2016/06/15/…

Alexandre Vaillancourt

Sure, use it in a loop, don't use it anywhere else :)

MickLH

Also their overflow behavior is defined, so they are ideal for modular arithmetic in GF(2^n)

when n = 8, 16, 32, 64

Alexandre Vaillancourt

2:37 PM

@MickLH Yeah, if you look at the video, this is one of the 2 reasons to use units given by that clang guy...

That's not typically when ppl use unsigned, though.

user92578

Smart stuff said by the people in the video, I'll definitely stop using unsigneds now

MickLH

Only stop using them when you should stop

Otherwise you're just letting your emotions make you a worse programmer

Alexandre Vaillancourt

I see it the other way around: the advice is not never use unsigned, it's to only use unsigned when you need to use unsigned, and these cases are pretty rare in game dev :)

I'm curious, what kind of emotions?

Sie

@MickLH What? You don't cry as you code? That's the only way I can code.

MickLH

Mostly religious because following advice just because its from someone cool is actually logical fallacy. But partly spiteful in this case

Martin Sojka

2:41 PM

@AlexandreVaillancourt Oh, you know, the kind of positive and negative feedback loop hormonally induced ones common to our learning behaviour, fellow humanoid.

Shaun Wild

Has anyone else in here ever had a serious fit of rage because they keep typing the same statement wrong?

I couldn't type a try- catch once and I just threw my keyboard at the wall and walked away from my pc for like 2 hours

MickLH

...java problems

Martin Sojka

Switching from anything to JavaScript and going for(int i = 0; ..., then wondering why the hell that doesn't work. Happens all the damn time for me.

MickLH

lol

Shaun Wild

Does anyone else see xD as sarcasm and only ever sarcasm?

Once you see it that way you can't unsee it

C# is better than Java xD

example

Martin Sojka

2:44 PM

It's not really "rage", more like being annoyed at myself. I should know better, but my fingers are faster than my brain.

Jon

a long time ago, i though lmao meant LAME

so everytime someone wrote lmao -- i was like, fuck you

MickLH

@AlexandreVaillancourt I agree that Tyyppi almost guaranteedly needs guidance but I think the way you had to skew the advice to get past his filter, makes it slightly misleading for anyone else

user92578

I thought that lol meant lots of love

Jon

ftw = fuck the world

Martin Sojka

@Tyyppi_77 Depends on context.

MickLH

2:45 PM

That's why I comment that unsigned isn't bad just misunderstood

user92578

wtf = why the face

Jon

lol

Martin Sojka

Why, thank you, darling.

Jon

lol is so universal now

DH.

And when it comes to LoL it's universal as well

Alexandre Vaillancourt

2:48 PM

@MickLH Ah hmm.. maybe. And about your other messages, fair enough.

@MartinSojka I thought programmers did not have emotions :P

DH.

They have, but they just don't show them

Unless they are drunk, them they show it very clearly

Alexandre Vaillancourt

hehe :P

Shaun Wild

@DH. Hahaha that was funny xD

DH.

It wasn't meant to be funny, so your sarcasm is pretty invalid

Lunch time, cya

Alexandre Vaillancourt

3:03 PM

@Almo another question that can be answered by 'You can't'!!

Almo

HAHAH THEY RULE

Shaun Wild

3:16 PM

@AlexandreVaillancourt What is?

Q: Convert orthographic camera to perspective camera

How calculate perspective camera from orthographic camera parameters (left, right, top, bottom, near, far) Actually I don't now how calculate fov for perspective camera from orthographic camera.

Shaun Wild

Your answer is quite smartarse and unproffesional if I'm going to be hnoest.

you could of at least mentioned a possible workaround.

Alexandre Vaillancourt

@ShaunWild By all means, give it a shot!

Shaun Wild

like have 2 cameras

And switch between them

Another 'You can't' !

Alexandre Vaillancourt

Answer it!

user92578

3:29 PM

^

Almo

@AlexandreVaillancourt upvoted. good answer.

Shaun Wild

No :(

I'll give reported

Or something

user92578

LOL

Alexandre Vaillancourt

@ShaunWild You'll give reported? What does that mean?

Almo

I didn't see anything insulting in that answer like "you're an idiot for trying". It stated the core issue (matrices not contructed at all the same way)

user4704

3:37 PM

You know, I really wish somebody would answer that damn question about Ogre PSSM shadows.

user92578

Hey Josh why does it show that you've modified this question?

Almo

doesn't show that for me

user4704

I dunno.

user4704

It doesn't show that for me either.

Almo

tyyppi makin trouble again, as usual. :)

user4704

3:40 PM

It may be because I closed it and then thought better of it.

user92578

user92578

Oh, that might be it then

user4704

Oh yea.

user4704

That's definitely because I closed it and reopened it.

user4704

I thought you mean it showed you an "edited by" which would be very weird

user4704

3:41 PM

(I opened the edit interface, but got distracted and closed it witohut submitting)

user4704

There we go, maybe that will encourage somebody to answer. I'm sick of seeing that question at the top of the unanswered list.

Alexandre Vaillancourt

@JoshPetrie nice @ 300 rep :P

Q: How can I get PagedGeometry grass to receive shadows?

I made the switch to Ogre3D (v1.7) and to using PagedGeometry. What I'm trying to do is make a simple scene with a terrain, some trees and grass. In a nutshell, I would like to achieve this kind of effect in Ogre: Transparent/cut-out shadows are implemented in PagedGeometry demos but I can't f...

c++ shaders ogre shadows billboarding

user4704

I had to pick a number that would make my rep even-ish.

Alexandre Vaillancourt

Hahaha, that will not remain like that for long ;)

user92578

3:52 PM

Hmm I have almost two days of dev time without interruptions as parents leave for a weekend trip tomorrow, so I should probably think about a nice project for the weekend

user92578

There isn't really any big features I want to add before GL, so I guess I should just be fixing bugs and maybe making levels

user92578

My weapons are randomly falling trough thin-enough (I think) floors and I can't reliably reproduce that bug so it's really annoying to try to debug.

Jon

user4704

"GL" is greenlight?

Jon

thinking of adding a touch activated dispenser.

user92578

3:57 PM

Yeah

Jon

kinda late in dev, but ...

user92578

@Jon that sounds like a great idea, and also looks pretty good

user92578

maybe the button's color should indicate what things the dispenser dispenses?

user4704

Try making a level containing all permutations of floor thickness and a cheat that lets you spawn a weapon in front of you with a button press?

user4704

And then hold the button down and hope the bug happens :D

user92578

3:57 PM

yeah that's actually what I'm doing :D

Jon

@Tyyppi_77 I was thinking it is orange, beause you have to press it

I want to force the player to have to exhaust all the blocks in the dispenser if it is orange

user92578

Oh that's solid thinking too

Jon

should be obvious once it is empty and it turns green

user92578

(makes sense)

Jon

also.. if you hold it down, there will be a secondary power gauge

i plan on using this for a boss fight :)

user92578

4:02 PM

right I was just about to ask about the boss level

Jon

yeah... so now I gotta re-design some dispenser levels... make sure the mechanic is well understood and whatnot

user92578

4:18 PM

Every god damn time I try to reproduce this bug it doesn't appear

user92578

Then I give up and move onto other things, and then spot the bug again

Alexandre Vaillancourt

Uninitialized variable? :P

user92578

I'm guessing not, that would probably show more often

Shaun Wild

REEEEEEEEEEEEEEEEEEEEEEEEEE

Alexandre Vaillancourt

Did your cat just sit on your keyboard?

user92578

4:24 PM

Maybe better luck tomorrow, I'll call it a day

Alexandre Vaillancourt

Go play now!

You have time :)

Jon

erebel55

sick

Alexandre Vaillancourt

@Jon nice!

Jon

thanks man, thats just the first rev

still needs to fire

Alexandre Vaillancourt

4:33 PM

What is it?

Jon

a touch dispenser

it will shoot out a block when you let go

Alexandre Vaillancourt

Ah, ok!

Jon

based on how long you hold it pressed

Alexandre Vaillancourt

The longer you press, the higher is the impulse force?

Jon

yep

Alexandre Vaillancourt

4:38 PM

Cool!

Jon

needs work, but yeah

Alexandre Vaillancourt

If you hold it for too long, does smoke come out of it and a non green block come out of it?

Jon

naw

just maxes out power

Alexandre Vaillancourt

Oh ok :)

PearsonArtPhoto

Still adding new features?

Jon

4:43 PM

apparently lol

PearsonArtPhoto

You know, mobile marketplaces tend to favor apps/games with more updates, it doesn't always pay to make the best game possible before releasing it.

Jon

good point -- however, I am missing a reward for completing my game

And this is part of that plan...

PearsonArtPhoto

Hmmm.

Well, keep at it then!

Noctrine

It's possible to complete :O

Some puzzles I just skipped.

Jon

they are all possible :P

Noctrine

4:45 PM

Does anyone know of a comprehensive script to test a javascript engine? All I keep finding is performance tests, and I'm too lazy to make one that goes "it works"

@Jon Under par?

Like there are some swinging ones, that to make it swing you have to click twice, and it's a par one.

Jon

well, the current build out there has all the pars messed up still

so i need to go through that and fix the issues -- I had a problem with the ID associations

Jon

4:56 PM

Man... i'm not sure about adding features now...

gonna have to go through an entire full dev cycle again

DH.

Release, add stuff later

Jon

I am also considering this...

DH.

That worked with Cut the Rope at least

PearsonArtPhoto

It's worked with almost every major mobile game.

Jon

yeah... and minecraft :P

PearsonArtPhoto

4:58 PM

In fact, it's incentivized to do so.

Jon

The thing is... GORB 2 would be difficult to pull off...

I would have to think up new mechanics

Glue, Wind, Switches

TouchDispensers

PearsonArtPhoto

Portals.

Jon

BouncySurfaces

aye.. Portals

The sequel would be nuts to code and design.

But if this one makes money you can bet I will make it

PearsonArtPhoto

You could do it, but you probably want to work towards finishing what you have now. If you want to, you could add new features in later.

Jon

it would have to be a new level pack after I ship

adding new features in the middle of what I release, would be weird.

DH.

5:04 PM

Cut the Rope released new level packs for free along the way

PearsonArtPhoto

As did many games.

DH.

After releasing 3~4 they went for Cut the Rope <Whatever name>, so you would need to buy again

Jon

Cut the Rope Miami

Cut the Rope Birthday

its marketted like a pile of manure now..

yet that style of marketing seems to be what works

so what the hell do I know.

Almo

you know what feels like selling out

that's what you know

Jon

I guess it is what everyone does though -- you have a popular named IP

So you use it in everything -- Angry Birds Cereal... Angry Birds Dog Poop Picker

DH.

5:12 PM

Oh and add fans to your game/in a DLC/level pack, I think that would add extra possibilities of solving levels that involve throwing the blocks

Jon

I should start the church of Gorb

sell this game tax free

DH.

And don't forget you have a /r/ to feed when you release it

MickLH

5:30 PM

@Noctrine sadly you're asking to exercise every facility of a turing machine :P

Noctrine

I should have better scoped that request yes :p

MickLH

If some algorithm that could do that does exist, I'm sure it will take infinite time lol

Almo

:D

MickLH

kindof a fun thought, how do you test if a programming language actually works as advertised in every possible bit combonation

Almo

you can't

that's equivalent to the halting problem, isn't it?

MickLH

5:32 PM

yeah, I think your best bet is proving the base cases and then proving the other infinity cases with induction

but then its verification, not testing
