Game Development

@Chris yeh csv and xml are also possible

@Don'tclickonmyprofile csv and xml are easy to write parsers for

If @KevinvanderVelden is around he might be able to help you with Pygame

Woo :D That would be awesome

6:53 AM

@Chris I know right... tell @KevinvanderVelden to stop being abusive, it doesn't help.

user92578

@Don'tclickonmyprofile I've always just programmed my own TMX loader

Morning Tyyp

user92578

Morning Hjor!

@Don'tclickonmyprofile doc.mapeditor.org/reference/tmx-map-format

@Tyyppi_77 Ihana!

user92578

lol

user92578

6:57 AM

I appreciate that, thanks

user92578

I've just picked a generic XML loader and used that

@Hjorthenify Thank you very much, I just noticed that it is possible to export it in json format :D Looks promising and easy to parse as well :)

@Tyyppi_77 Pretty much sums up my finnish.
@Don'tclickonmyprofile Get coding! :D

user92578

:D

@Hjorthenify alrighty :P thank you!

7:03 AM

Well I've worked hard for myself to get where I am, I don't claim to have some vast library of knowledge either. I just have fluid intelligence and can solve a problem. Sorry if my solutions end up better than what you memorized from your textbook. I'm not trying to threaten anyone's intellectual dominance... ( @MartinSojka @Ali.S @KevinvanderVelden @tereško )

"Can't we all just get along?"

@MickLH Wait, what, why am I even mentioned? :D

I don't know maybe I'm just projecting, I didn't want to miss anyone

And for the record, I'd advice against using the CSV format for Tiled export. Use something structured, like XML or JSON, so you can utilise the object layers for metadata like "trigger areas", "enemy spawn points" or "NPC paths" ...

@MickLH Projecting what exactly? I just don't get the context.

I've felt like we've had rough times in the past

@Don'tclickonmyprofile @Hjorthenify I'm somewhat around. In a train

7:16 AM

If so, I don't remember any of it.

Meh the past doesn't matter anyways, mainly I just want to beat kevin to a pulp while hysterically screaming "BE NICER TO ME BE NICER BE NICER"

and I think ali is ... slow, and I'm so proud of what I did to teresko

See, still missing context now. Who's Teresko? :D

that guy idling up there next to jon

Free WiFi in the train is great. But when there's a delay everyone tries to use it so it's really slow :(

@KevinvanderVelden You think that's bad, you haven't been in a train with my colleague. He tried our file transfer management software we recently updated for the Swiss television while on a train - by uploading a video file several GBs in size over their WiFi.

Our software worked great, the file got transferred without problems ... eventually.

7:23 AM

Ha nice

It's actually holding up pretty well I think.

Though of course it is in the Netherlands so there's not as much infrastructure to set up

In our case, it was a German ICE from Zürich to Frankfurt am Main.

Off the train now. Back in a bit

@MartinSojka for context...

@MickLH Ah yeah, the Latvian guy. What, did you show him the error of his ways? :)

ahhh that's a good read :)

7:28 AM

@MickLH Just your usual internet flamewar then? Sorry, but I'm unimpressed. I was expecting something related to game development. :)

I never set out to impress you

I won't ask why would I care what you think of me, you can do that internally.

And I never claimed you did. :)

What I am setting out for, what I am asking for, is an end to the hostility

@MickLH Hey now, you're changing subjects here. I wasn't talking about what I think of you at any point, nor do I intent to. Ad hominem is not my style.

Too quick to assume I'm changing subjects.

Assume I am competent, and then re-attempt to parse.

Hint: I am explaining why your message was irrelevant.

7:32 AM

My message was a comment on the text you posted. As such, it was relevant to the text, and commenting on it.

It was an anecdote with no significant contribution towards the ultimate goal, but loaded with an emotionally uncomfortable tone.

It was plainly unnecessary, and even outright counterproductive

Wait, you had a goal with sharing it? If so, I missed it. Can you spell your goal with me in more concrete terms then?

My goal with that tangent was to provide the context you requested.

My ultimate goal here is to find a mode of correspondence which is effective and emotionally comfortable for us both.

And you succeeded with that goal already, so nothing I could do or say could be counterproductive.

Assumed too soon again.

I had said, "no significant contribution towards the ultimate goal"

The ultimate goal being finding our effective mode of correspondence, which we clearly have not.

7:36 AM

No, I'm not assuming anything. Your goal was to provide context. That context was provided. As such, the goal was reached successfully.

See, you are plainly wrong.

That is not my goal. Period.

Do not quote my message.

Quote this one: > My ultimate goal here is to find a mode of correspondence which is effective and emotionally comfortable for us both.

And so, each of these counter-productive anecdotes has been a waste of time, and a lead in the wrong direction objectively as they each constitute a misunderstanding.

So far, our current mode of correspondence is as effective as I can imagine it would be, given the constraints, and I don't give a damn about anyone's emotional comfort, in particular not mine.

The emotional comfort of yourself and others is highly important, and I suggest you integrate an awareness of it into your social interaction algorithms

I am le back

I tried. It led to loss of effectiveness. Nowadays, I just say what I want to say and try to be as concise and helpful as I can manage.

7:40 AM

This claim is not baseless, in fact it is based in physiological effects of comfort and stress on communication

Looks at @MartinSojka's text Yeah I'm still glad I've put mick on ignore

On both communication and cognition actually

I'll just say, for my own ego's sake, that @KevinvanderVelden uses python

And just like that, I feel so much superior

(Because I truly am)

If we're ~~chatting~~ ranting about how some software is clearly inferior and created by "literal" monkeys, why the hell did the SAX developers feel the need to output diagnostic messages and non-fatal errors on the standard error output as a default?

Martin, you're killing me, I also wanted to point out that his poorly produced nethack clone also had no innovative features and sub-par gameplay, while also delivering immensely horrible frame rates on high end machines.

But now I look like an angry dick

It's annoying enough when you use the library yourself, but downright infuriating when some other library uses it and doesn't give you a chance to change the parser's settings unless you feel like using reflection ...

7:46 AM

But I'm not angry at all, it just makes me genuinely happy to check logically at the people who are abusive towards me, and see that in fact none of them have notable accomplishments

@MickLH What, like this? :D

lol

heya @MickLH

hey @Jovito

Ever used browserify?

7:48 AM

Yes but I don't even remember what it was

Oh yeah the JS loader

(For those who don't get the reference, that's an angry Dick Cheney ...)

I hate node

I'm getting a stupid error and I can't figure out why.

Further, I take deep pleasure in knowing that those who are abusive towards me have consistently had embarassing work portfolios, which gives me strong confidence that their views are fueled entirely by cognitive dissonance.

Story of my life.

7:50 AM

I don't know why I lumped you in, @MartinSojka

I should probably stop reading the transcript, @Mick you should honestly probably talk to a psychiatrist about this

wtf is going on

Oh man...

@MickLH For the record, I don't feel lumped in, but if you did, I still wouldn't have cared. Getting criticised for my own stupidity is a good thing, no matter the tone. It allows me to grow. Or at least know myself. Some of my vices I don't want to change.

@KevinvanderVelden yay that makes me sure you're actually proud of that ... "program"

Like, if I wasn't such a damn lazy bum, I'd never have started programming computers to save me time.

7:52 AM

@MickLH what program are you talking about?

@KevinvanderVelden The sub par nethack clone

The one with no innovative features and horrible performance lol

@MickLH the GDSE gamejam one that I made in 48 hours while learning a language and a library?

Oh yeah that's terrible for a first gamejam

Heheheh see, he's proud of it

To be fair, it's hard to make a good clone of something that's been refined for over three decades now.

Also it wasn't intended to be a clone of nethack

But using a library made specifically for ASCII/tileset based roguelikes does kinda box you in a certian graphic style

7:55 AM

There's a library for that?

libtcod :)

I thought everyone just used ncurses and a terminal ...

God I love it!

Well that doesn't quite work on windows =p

Anyway, saved for future reference, thanks.

7:56 AM

Smugly bragging about a library that does everything, while also defending his quality due to lack of time

mmmm the proud tastes so good

@MickLH the hell is wrong with you? Honestly

Sigh nevermind

@KevinvanderVelden I just want you to be nice really

Refreshes so the mick is gone again

PLEASE

@MartinSojka it's quite useful, also has implementations of field of view, bsp tree dungeon generation, a* path finding

7:57 AM

I really picked a winner there lol, I thought he was proud of that abomination but man am I glad he's this proud

GO AWAY ERROR, NO ONE LIKES YOU

And bragging about how the library does everything... it's like he can't remember that he just defended himself on time constraints a moment ago

@MickLH That's how it usually works, really. People are proud of things they accomplished even if those things seem trivial to others ... or even if they are things they had no significant contribution to ("proud of my country" and such) all the time. I'd say to let them; it provides a nice motivational boost.

I don't want to bring him down a peg, don't get me wrong. I just really enjoy knowing that I'm a higher class programmer

@MartinSojka Exactly, I'm glad he's motivated, his motivational boost applies to me with a multiplication factor >1

@MickLH You're not doing the "... let them" part very well though. :)

7:59 AM

@MickLH can you shut up?

@MickLH you are still adorable

So, what have you released?

@Jovito Click on his name and then ignore :)

It's mostly all under NDA

Oh, ok.

Also, can we please not flag every other chat message? We're just chillin' here.

But some control systems for heavy machinery, control systems for medical devices, digital testing systems for state testing

A few "cool" things

8:01 AM

@MartinSojka wait, is he doing that again or is someone else?

Expect to see equipment operator certification go digital in the next few years, that's my code

At least in the US

(Curse my lack of 10k network rep! SO CLOSE)

OSHA already wrote the laws in our favor

If you think NDAs are bad ... I have friends who are coding combat UAV software. :D

@KevinvanderVelden You don't see who is doing it, and I don't really care.

NOW I GET IT

8:03 AM

@MartinSojka well, is it everyone but him? Then it's probably him

@Jovito can you pipe down? lol

Anyway, back to coding. It's been nice chatting with you all.

OH YES BABY

THE ERROR IS GONE

Peace @MartinSojka

SOMEONE KISS ME

8:04 AM

@Jovito BEGONE ERROR! BEGONE!

My roommate is supposed to be back by now, I wonder what's up

@Jovito hug Kisses are unhygienic.

@MartinSojka well, I recall reading some preliminary study that proposed that kisses are for sharing germs so you strengthen the immune system

(Well, I recall an article about the study)

mmm herpes

(Programming/math papers: Yes. Biology papers, I have no idea what you are talking about)

8:06 AM

@MartinSojka That made me feel... AWESOME! PULLS YOU CLOSE AND HUGS YOU LIKE A MAN

Hmm, I have a stylish window open, what did I want to do with it again

@KevinvanderVelden I did.

@KevinvanderVelden u dont have 4G?

real fortran programmers aren't integers.

@MickLH honestly, maybe you should talk some more, and I'm not saying that to belittle you. Because I was never against you until for no reason known to me you started going on a rampage against me, even after constantly flagging me for no reason I gave you a second chance, maybe I said something you took as an attack but that was never my intention. I don't want to have you on ignore but you're making it really hard not to.

@Hjorthenify I do (well, 3G), there's also free train wifi, the somewhat around bit was because mobile is horrible and I wasn't sure how well the wifi would work

8:20 AM

@KevinvanderVelden Alright well talk through it, I'm on my crazy pills

@TheMuffinCoder Your modeling reminds me of pigart (look it up on youtube).

heya @AidanMueller

Someone made a voxel based game for the ludum dare jam O.o ludumdare.com/compo/ludum-dare-33/?action=preview&uid=2297

| PigArt | BLENDER Timelapse: Low poly isometric work

►

@KevinvanderVelden Ah alright :)

8:25 AM

@KevinvanderVelden Hey, it's McFunkyPants.

He does one game a month.

Also the ludumdare site is loading really slowly, I blame indiegames

The website, Onegameamonth

Aah cool

Why indiegames?

Because they just released an article (well I think just, not sure) so everyone is hitting the ludumdare site and the ludumdare site is crying

8:27 AM

@AidanMueller Why wanted to ask you about the solution you gave here: gamedev.stackexchange.com/questions/69339/…

I hate that I cant use my dedicated GPU for firefox -.-

@Jovito What is it?

It really isn't the best solution.

It checks collision twice.

I'm getting some incorrect collision resolution in my game while using it (your solution).

You may want to consider making your own method that works on corners instead.

Exactly, the corners.

8:29 AM

@Jovito I'm not responsible for personal injury using my solution*

@Jovito What do you mean?

What's wrong?

How can I send the link to you privately?

Why private?

I don't want to share my game just yet.

You could PGP encrypt it, but public would be easier.

You could just share relative code.

Or do a GIF.

Ok.

I can do that.

8:30 AM

Plus I'm on Linux.

I could send the link to your email or something.

Going through the whole game code is counterproductive anyway. Can't you extract the parts which are the problem as a stand-alone program and put that on Github, Bitbucket, SourceForge or similar?

Nobody wants to steal your collision code if it's not working :D

Nobody wants to steal your code here anyways.

I'm not worried about the code.

8:31 AM

If you've been writing unit tests like you should, the "extracting" shouldn't be hard either.

I don't do unit testing.

Unit testing is for people who want to make debugging easier. Where's the fun in that?

4

Heh

Unit testing games is hard

Seriously, I don't.

@Jovito Please state the problem.

Brick! Its a game about brick!

Though adding unit tests for, say, a specific data structure is the best

8:33 AM

I usually "just" write unit tests for specific systems (which is why an ECS is such a nice thing to have: Lots of already separated-out systems)

Gomers!

hahahaha

@KevinvanderVelden Only time i've written a unit test was for my heap tree

@AidanMueller It would be easier if you saw it yourself.

8:34 AM

@MartinSojka ooh true, I never thought of that for the ECS

Though the drawing bit is of course difficult

@Jovito Y u no gif?

Send me a

2

Jif!

I will always pronounce it like it is spelled, if only for the fact that that is the dutch word for poison

Jovito, could you upload some poison?

By the way, games often solve the "how do I stick to the ground/wall" problem by literally having a bunch of "sticking to the ground" and "sticking to a wall" flags on the moving entity's collision component.

Like ... if( onGround ) { force.y = max(force.y, 0); /* assuming y axis goes "up" in the positive direction */ }

8:38 AM

I'm solving a collision between a circle and a rectangle. Sometimes when the circle collides with the rectangle's corners, the collision is resolved in the wrong axis. Otherwise, if the circle collides closer to the midpoint of each side of the rectangle, it works fine.

Make sure that you are doing this:

x += xVelocity
resolveCollision();
y += yVecolcity
resolveCollision();

You could also try moving and resolving the axis that has a higher velocity.

I'm doing that. Did you see the code?

No. You took it down.

each(['x', 'y'], function(axis) {
    circle[axis] += velocity[axis] * dt;

    var collided = _.filter(bricks, function(brick) {
        return utils.testCircleRectCollision(circle, brick.rect);
    });

    var revertVelocity = true;
    _.each(collided, function(brick) {
        brick.handleCollision();

        var depth = rect.getIntersectionDepth(brick.rect);
        rect[axis] += depth[axis];

        if (revertVelocity) {
            velocity[axis] *= -1;
            revertVelocity = false;

What lang is this?

8:44 AM

js

Why do you store axes in arrays?

Nothing is necessarily wrong with it, just curious.

its not an array

OH, I see now.

That's just not how I do JS :D

@Jovito Try checking the higher velocity first.

Remember to do absolute value.

Why would that help?

Because when you do X += velocityX, you are moving it past the edge.

It's probably not perfect, but it could help at least a bit.

8:49 AM

Alright, I'm going to try that.

To expand on what I said, think of an edge that is in the way of a falling object. The object has a bit of horizontal velocity. The object has mostly downward velocity, and would hit the edge, but because the X gets checked first, it moves out of the way of the edge, making it fall past.

What? That last message is confusing me.

@Tyyppi_77 I was apologizing for potentially making you close the tab.

Oh

user92578

Shouldn't've shut my brains

Could he be more sorry?

user92578

Wait you probably can't do that "Shouldn't've"

Chris

8:55 AM

It's English - you can do whatever you want :D

Shouldn't've

Probably not correct, but looks correct.

Chris

shouldn't've

== English == === Etymology === shouldn't +‎ -'ve === Pronunciation === (US) IPA(key): /ˈʃʊdəntəv/, /ˈʃʊdn̩təv/ === Contraction === shouldn’t’ve (nonstandard, informal) Contraction of should not have. ==== Synonyms ==== shouldna (colloquial)...

I was right!
