Hi.

user4704

Hi.

Hjorthenify

07:08

Going over the ++i and i++ operator is apparently very, very, very hard -.-

user92578

07:35

Hi guys

Hjorthenify

Hi Tyyp. Feeling better?

user92578

Yeah, a lot better

Hjorthenify

Good!

user92578

I've been kinda isolated from internet and news for a few days

user92578

Didn't dev, didn't open Facebook, didn't open the curtains

user92578

07:37

Now I'm like week behind on school and dev stuff... but I'll just spend the weekend doing as much school stuff as I have the power to do

Hjorthenify

Yeah.. Good idea

What did u do instead? Just stayed in bed?

user92578

Watched stupid reality tv

Hjorthenify

Ahaha so basically tortured yourself? :P

user92578

lol

user92578

Am I allowed to use images from Wikipedia in my presentations?

user92578

07:40

I'm not going to do much school stuff today, but I just need to quickly change an image in my presentation

Lokkij

In high school (or at least in mine) you can use any image without citing the source

And wikipedia releases all its images into public domain IIRC

user92578

hmm I think the wikipedia page says "Fair use"

user92578

Okay, that's done now

user92578

So what has happened in here?

Hjorthenify

Yes. Wiki is public domain

I had a struggle with my school's programming assignment system yesterday

Me, Jon, Pip and Muffin decided to collaborate on UE4

Ali released an app

user92578

07:49

oh right yeah I betatested it for him

Hjorthenify

I think that's it :P

Kevin van der Velden

Ooh yeah, UE4 jam this weekend

Lokkij

Ooh, we'll be taught pointers next week.

Hjorthenify

Woooh!

Kevin van der Velden

Also, hi chat

user92578

07:52

Hi Kev

Hjorthenify

@Lokkij We will be taught about classes next week(woooh......)

Lokkij

Exciting!

Hjorthenify

Very >.>

Lokkij

We're going through it quite quickly

I would be a little overwhelmed if I couldn't program already

Hjorthenify

I wish we did the same. What language are you in?

Lokkij

07:54

C

user92578

Ugh

Lokkij

You?

Hjorthenify

Java

Wish it was C though

Sadly you're not required to take C or C++

Lokkij

You can though?

Hjorthenify

Yeah

and I will

But I feel like low-level languages should be required for computer science class

Lokkij

07:56

Right

If you're doing CS it does seem a bit weird to not be taught C/C++

Hjorthenify

Yeah exactly

RhysW

08:18

@Jon oh btw i forgot to mention yesterday, thanks for the tips on the screen managing, pointed me in the right direction

user92578

08:59

Ugh I can't decide on a good architecture for placing dynamic entities

user92578

I would eventually need some sort of property editor for them

user92578

Health, damage and other cool stuff

user92578

So I'd need flexibility for that

user92578

then I need to be able to just switch to the test mode and let the entities move and update

user92578

but once I switch back to edit mode, I'd need them to flip back to their original positions

user92578

09:00

Maybe I should nail the property editor first

user92578

programming something like that doesn't seem too pleasant tough...

user92578

hmm

user92578

09:39

I think my headset broke finally

user92578

The plastic part of the wire broke like a month ago

user92578

It's been cutting off my left ear sound randomly since

user92578

I can see broken wires

Jon

@RhysW np

@Tyyppi_77 solder them back together

user92578

09:54

I don't think I can do that

user92578

A) I can't sold (is that the verb???)

user92578

B) They're really small wires

Jon

it doesn't take a rocket scientist to solder

heat up wire, drop lead

connect wire to molten lead before it cools

user92578

well true

Kevin van der Velden

@Tyyppi_77 to solder is the verb

user92578

09:55

ah

user92578

thanks

user92578

it looks quite broken

user92578

won't soldering connect wrong wires to wrong ones?

Jon

i fix stuff like that all the time

not if you do it right, lol

user92578

it's broken right at the edge between the wire and the volume control "block"

Jon

09:58

might have to use some scrap wire

user92578

not a big surprise

Jon

shave off some of the packaging on that volume control

user92578

one part bends, and the other doesn't

user92578

what do you get?

user92578

a broken part

user92578

09:58

fuck ghost recon phantoms wont start

Jon

metal gear solid phantom

user92578

im still a bit too sick for effecient programming

user92578

but now the one game id like to play wont start

Jon

efficient

user92578

oh there are all sorts of broken wires

user92578

10:00

broken red wires

user92578

broken copper-color wiresd

user92578

broken blue wires

user92578

broken green wires

user92578

or maybe that's just one turquoise colored wire

user92578

but yeah, the game says that it's the wrong version

user92578

10:01

I already reinstalled it

user92578

ubisoft at it again

Jon

Ubisoft, where the games are built around DRM

user92578

fuck this

user92578

I mean

user92578

if re-installing still gives me the wrong version

user92578

10:20

I guess I should get on to the programming...

user92578

But I'm totally in a procrastination mood

Lokkij

I'm always in a procrastination mood

user92578

I just don't want to jump into a big new feature while my thinking might not be at 100%

Lokkij

Man I looove (web)comics with a really cinematic style

user92578

10:37

After the level editor is done I really gotta start de-broforcing the game

user92578

11:00

Thoughts on a new roof?

user92578

Jon

Microsoft is probably gonna get sued

A lot of people that never reserved windows 10 -- have been getting Windows 10 install files silently without consent

Some people, it made them go over their data caps

Costing them money

Force Updates, they can possibly fight that as their case would be "to secure PCs" -- But this forced windows 10 install file thing is gonna bite them in the ass.

Pip

11:23

morning

user92578

hi

Hjorthenify

@Pip Morning!

@Jon Microsoft is getting greedy

Hjorthenify

There's a fucking cat trying to commit suicide at my college.. It tries to open up the window from the top floor -.- Noisy as fuck

Hjorthenify

12:16

Adds exclamation mark to "Hello World"

Fails the test

user92578

wtf

user92578

Hello World is supposed to be with an exclamation mark

Hjorthenify

Well.. That is a true story..

our teacher had a surprise test for us today to check how much we where paying attention. Those who did less that 50% have to do a quite long assignment over the weekend.

My friend failed because the system didn't accept "Hello World!"

Jon

12:45

can't he follow simple instructions, gosh!!!

you can get the witcher 2 for $3 right now

user92578

FUCK

user92578

I just made this really nice test level

user92578

forgot to save

BeamNG Drive Mods Gameplay - Jumping the Grand Canyon! (Canyon of Speed)

►

soft body physics car game

looks awesome lol

user92578

the nice thing is, that already now the level editor allows for really quick iteration

RhysW

12:59

@Jon plays awesome too

Jon

you bought it?

RhysW

have had parts of it for a while, when it was first being announced

user92578

Added these thin platforms to the editor:

user92578

Hjorthenify

@Tyyppi_77 Add moss or something hanging from them

Hjorthenify

13:47

@Jon You around?

Jon

I'm a little round

Hjorthenify

Do you know how i can convert a number into a string which takes up 2 chars? So if the number is 5 the string will be 05 but if the number is 12, the the string will be 12 as well

OMGtechy

I have found a bug in VC++ :D

I don't know why I'm happy about it

Jon

ToString("D2") I think

Hjorthenify

Nailed it! Thx :)

Jon

13:50

np

Almo

hey

:)

Joe

good morning GDSE

Almo

hey joe

Joe

If anyone deals with VMs or dev ops, I attended a very cool talk / meetup on Puppet "Coding your Infrastructure" and the tool is very cool

Kevin van der Velden

I've read good things about it

Joe

14:02

I use vagrant a lot and have been putting together hackish solutions to try and eliminate disparity

little did I know Vagrant natively supports puppet and its super easy and awesome to get a manifest going

Kevin van der Velden

Fancy

Joe

well in any case, thats my fancy find of the week

user92578

@Hjorthenify Might work, I'll see, thanks

Don't click on my profile

kek 9gag.com/gag/a9PvgB6

Almo

@Don'tclickonmyprofile too bad it doesn't also illustrate VSync

and you always get a pedant who says "NTSC is 30 frames per sec but 60 fields"

well, a field is full screen half res, and if the engine updates between fields, it doesn't matter if it's 30 "frames" it's still 60 updates

and each NTSC "frame" will be composed of two fields made at different "times" in the engine, so it's effectively 60 FPS anyway

Joe

14:18

i play at 180fps... because i have 3 monitors... owned

if i surround myself with 6 monitors i could play 360 degress at 360fps? mind blown

wonders if he could rig an xbox 360 to push 6 monitors #justsayin

user92578

@Joe nice

user92578

the monitor count I mean

RhysW

@Don'tclickonmyprofile I was doing some testing in a little thing i made the other day, 5300 FPS

Joe

eh its hackish... im constantly struggling trying to standardize

user92578

So how's this? (the thing that the player is standing on)

user92578

14:25

RhysW

@Tyyppi_77 looks good! A little repetitive though, maybe some plain some mossy?

user92578

Yeah I'll surely add atleast one variation tile

RhysW

i really like your art style

user92578

thanks

user92578

One day I might have to redo most of it

user92578

14:27

It looks a lot like Broforce as it stands

RhysW

it seems familiar yet different

user92578

But thanks a lot, hearing that really makes me trust myself more

RhysW

no problem, i've got used to looking at my own stuff which really pales in comparison, lots of block colours as placeholders for well everything

Lokkij

What are you creating Rhys?

RhysW

at the moment? A mess

Lokkij

14:34

Hahah

user92578

Yeah already one tile makes a big difference. I'll probably add another one just for the sake of it:

user92578

RhysW

not got any particular project being worked on right now, picking up some new things, working through some tutorials / guides to get a feel for it, so lots of pong clones etc

Lokkij

Ah cool

Joe

@Tyyppi_77 much better

user92578

14:35

Maybe I should tone down the moss a bit

user92578

So reveal a bit more of the wooden platform behind

Lokkij

Pong/breakout clones are awesome when learning a new technology

RhysW

yeah, just getting started now with some of the 3d stuff, having fun

Jovito

I'm making a breakout clone: 45.55.231.155

I still have to optimize it for mobile, but I'm almost done with it.

RhysW

'Just let me play' lol love it

user92578

14:38

Nice work Jovito

Jovito

thanks :)

Joe

@Jovito looking cool! you should start the game with a random angle on the incoming ball

user92578

C++ masters around?

RhysW

I like the backing music, repetetive but not annoying

Jovito

@Joe That's the classic way, right?

Joe

14:39

classic way i think you start with the ball on the paddle? and press to hit it?

user92578

If A has a virtual destructor, and B inherits from A, but doesn't have destructor declared virtual, and if C then inherits B, does B's destructor get called?

Joe

we should look into that

RhysW

@Joe 45 degree angle onto the paddle from the right to the left seems to be the typical manner.

Jovito

I meant classic as in the original game.

I think the ball came at a random angle.

I'm not sure though.

Joe

i think to me the method is irrelevant, but the desire is to have more variation in that start

Jovito

14:41

@RhysW I still have to fix the sfx.

RhysW

hmm youve made me doubt what i remember now

Joe

i could start this up and AFK

come back and still be safe on my first life

RhysW

@Jovito can i make a graphical suggestion?

Jovito

@Joe Yeah the game pauses when the tab becomes 'inactive'.

@RhysW Sure

user92578

Or you could also make the ball bounce from the corners of stone

Jovito

14:42

You can also pause it by pressing enter.

Joe

@Jovito oh what i mean is it starts for me at a perfect 90 degree perpendicular to the paddle

so unless I move i will never die

i feel like the default state needs to be... move or die

Jovito

@Joe You will if the time runs out.

RhysW

at the moment all tiles still in the level all go to their 'shiny' animation at the same time, and it's a little weird on the eyes. Maybe offset them from eachother a bit? So all the purple ones are at the same time, blues at the same time ect? not sure if what you have at the moment was intentional

Jovito

I could delay the tiles to make an 'ola' type of animation.

RhysW

but other than that nice work! I sucked at it and failed the frist level though :(

Jovito

14:45

There's a gui that only shows on mobile, but the perfomance is not great.

@RhysW cool, thanks

Hjorthenify

There's a runtime error in my code and it(the codechecker) wont tell me which or what the inputs are :(

Been running a fuzz test the past 5 min, but no error -.-

Noctrine

@Joe Puppet is super cool.

Joe

yes it is! I've had a few dev environment setup scripts but... apparently I've been doing it wrong

Jon

@Jon do you play often?

Jon

user92578

So I had this cool idea of a transition where the screen is first filled with black, and then small grid pieces start to fade off

user92578

Turns out it looks just awfull

user92578

15:28

So first the screen is faded to black with a simple fade transition

user92578

And then that happens

user92578

Oh now that I look at that I should probably remove the publish button as it doesn't work

Almo

I may have found a desktop image I'd like to use

zuqling.deviantart.com/art/LoL-Piltover-Popo-425633648

user92578

Kinda cool

Almo

I love the donuts that always show up because of Officer Vi's official art:

she's holding a donut in her massive glove, Officer Cait's in back with a box of donuts, and that's jinx lounging in the hole of the donut shop sign

user92578

15:43

hmm

user92578

I should probably stop executing brushes every frame

user92578

15:58

UNDO WORKS

user92578

hold on, i'll make a gif

user92578

There's no redo

Almo

MUST HAVE REDO

;)

lookin good dude

user92578

thanks

user92578

16:00

and

user92578

i guess...

user92578

:D

Lasse

I read all that and then switch to twitter and I see this: twitter.com/VisualStudio/status/642367008735150080

how fitting is that

everyone are buzzing about redos

user92578

LOL

user92578

So how would one implement the redo thing?

user92578

16:03

Currently I use the command pattern and a stack for the undo

Lasse

how did you implement undo?

user4704

The opposite of that. ^

user92578

So each brush has an Execute() and an Undo() method

user4704

Whenever you put something on your undo stack, put the inverse on your redo stack.

Lasse

put stuff in the redo stack and everytime you do something else than undo clear the stack

user92578

16:03

Ah

user92578

fuck I'm starting to run out of F<something> keys

user92578

I'm actually really proud of myself that I planned ahead and included the command pattern

Lasse

well you have alt and shift still, right?

user92578

true

user92578

but F1-4 are for my editor button hotkey

Jovito

16:06

hi @Lasse

user92578

F5 toggles debug data

Lasse

hi

user92578

then F9 is for console

user92578

F10 reloads the content

user92578

well I guess not that many

user92578

16:08

Wait

user92578

I need to push the things I redo back to the other stack, right?

Lasse

back in the undo stack, of course

user92578

Oookay

user4704

Once you have undo, redo should be pretty trivial.

user4704

There are one or two little behavioral edge cases related to when you clear what stack... but the fundamental tech is the same.

user92578

16:12

So the current approach is: When the mouse is moved to a new tile, a brush is executed and pushed to the undo stack

user92578

When undo keys are pressed, the brush is undoed and moved to the redo stack

user92578

And when redo keys are pressed, the brush is executed and moved to the undo stack

user92578

Oh and every time I execute a new brush (the first part), I clear the redo stack

user92578

Uses two std::stacks

user92578

and a little bit of code duplication

user92578

16:14

Seems to work great

user92578

Now it's just a matter of programming the Undo methods

user92578

Which might be just inverting the Erase-value

user92578

But I'm not sure

user92578

When would one clear the undo stack?

user4704

The way we did this at ArenaNet was not to explicitly have an Undo method, but a an Undo command

user4704

16:18

Every command had a property called Undo, which was a command that would invert the command.

user4704

So if you constructed a CreateObjectCommand() and didn't explicitly set the Undo property, it would create a RemoveObjectCommand and assign that to its Undo property.

user4704

And so on.

user92578

Ah

user92578

My brushes (or commands) get a boolean to their constructor telling whether they should erase or place tiles

user4704

I guess actually that happened had a higher level (transactions rather than commands) but still

user92578

16:20

So my (currently) only Undo method in the Terrain brush looks like this:

user92578

void CLevelEditorBrushTerrain::ExecuteBrush()
{
	if (!m_Erase) PlaceTile();
	else EraseTile();
}

void CLevelEditorBrushTerrain::UndoBrush()
{
	if (m_Erase) PlaceTile();
	else EraseTile();
}

user92578

But back to the one question I had, does one ever clear the undo stack?

user4704

Yes.

Kevin van der Velden

When one runs out of memory

user92578

Haha right

user4704

16:24

There are invariably some operations that you won't be able to undo across (for us, that was "revert all my changes" mainly). So you'll want to clear it then.

user4704

Ideally you have as few of those as possible, but sometimes you run into technical walls.

user92578

Ah, I see

user92578

But eventually this will mean (at a high level) maintaining two things for each command: the "do" part, and the "undo" part?

user4704

You also may want to limit the stack size to avoid running out of memory; it's better, I think, to predicticably limit the stack size than to randomly (as far as the user is concerned) clear the stack due to memory pressure.

user4704

yes

user92578

16:25

Oh I just remembered that you're the expert (also) when it comes to tools development.

user92578

Anyhow, I gotta go now. Thanks a lot guys!

Almo

PSPad does trim trailing whitespace, but is overzealous.

user4704

17:10

By trimming leading whitespace too?

user4704

and maybe all that in-between stuff

user4704

just for good measure

Almo

if you cursor is tabbed forward to enter an indented line, you leave the editor window, use another app and come back, it puts the cursor back at the start because it trims trailing whitespace where the cursor is on regain focus

Jon

17:24

oh man, the subway is kicking in

Lasse

you smoke it or what?

Jon

i got it toasted
