         if ( this.tiled ){
                ctx.translate(t.position.x, t.position.y);
                var finalPattern = ctx.createPattern(this.patternCanvas, "repeat");
                ctx.fillStyle = finalPattern;
                ctx.fillRect(0, 0, t.size.x, t.size.y);
                ctx.translate(-t.position.x, -t.position.y);
            }

that worked... but now i have horrible tearing

i can deal with the tearing later i guess

Kevin van der Velden

Though... there's only 4*3*2=24 cases where you would actually have 4 different types, if I complicate the code a bit to create a list of all intersections with 2 types, and a list of all intersections with 3 types

TheMuffinCoder

@Joe :P wait dont do that :

lol i was trying to make a example for u with jsfiddle

But its giving me problems with external images xD

Before u translate do ' ctx.save();'

And once u finish drawing that do 'ctx.restore();'

This way it saves current context before u translate it

Joe

then i dont need the second translate?

TheMuffinCoder

Nope

Joe

ill have to read on it

TheMuffinCoder

18:03

Then when u do restore it restores the context back to before u translated :D

Joe

how many K do you think i need for sounds?

TheMuffinCoder

wait let me check mine :P

@Joe all my sounds and images zipped together are 4kb

@Joe

if ( this.tiled ){
ctx.save();
ctx.translate(t.position.x, t.position.y);
var finalPattern = ctx.createPattern(this.patternCanvas, "repeat");
ctx.fillStyle = finalPattern;
ctx.fillRect(0, 0, t.size.x, t.size.y);
ctx.restore();'
}

Try this :D

Almo

dood use the "fixed font" button when you paste code

TheMuffinCoder

Master almo, can u plz tell how i could do it?

D: i cant do it anymore, no more edits allowed

Almo

if(this.tiled)
{
    ctx.save();
    ctx.translate(t.position.x, t.position.y);
    var finalPattern = ctx.createPattern(this.patternCanvas, "repeat");
    ctx.fillStyle = finalPattern;
    ctx.fillRect(0, 0, t.size.x, t.size.y);
    ctx.restore();
}

@KevinvanderVelden Short answer: Yes.

Kevin van der Velden

@MartinSojka Long answer: You need a shitton more variants and data

Martin Sojka

@KevinvanderVelden Long answer: It's a bit complicated. Some things (like when the "outside" tiles form two distinct groups, for example in tile 7 or 17), you get this automatically as long as each "group" consists solely of the same "outside" terrain.

And no, it's not a "shitton" really.

Almo

You sound like Hiemerdinger... "Hmmm... not enough variables. Not nearly enough variables!"

Kevin van der Velden

Well, I was talking about allowing tiles having arbitrary neighbours

So, desert on the top, water on the left, plains on the bottom and mountain on the right

Martin Sojka

The trick behind this sub-tile setup is that "arbitrary" means "At most three, and even that only in a few cases".

TheMuffinCoder

18:17

xD hey just wondering, do u guys create your own music for your games? (mixing loops doesnt count)

(if u did, how did u learn to write songs D:)

Kevin van der Velden

@MartinSojka that latter doesn't really work if you don't know that in advance

Icy Defiance

@Almo just sprinkle some more variables on top of the code, like salt

Almo

ahhaha

Martin Sojka

@KevinvanderVelden Ok, off to Inkscape to make another visualisation then. :)

Icy Defiance

is it okay to use single letter variable names when they're just there for flavor anyway?

Martin Sojka

18:21

Single-letter variable names are ok when you use them consistently. I typically use i, j, k for indices; e for errors; x, y, z for position or direction; u, v, w for texture location; r, g, b, a for colour information.

Almo

that's pretty reasonable there martin

Joe

if it works for you seems fine, but if you need to show that code to someone else could get annoying - most of those are straightforward though. Im of the school that if you are using any modern IDE long variable names shouldn't matter because we all should have autocomplete. you should only ever have to type the full thing once

Icy Defiance

I was completely joking with that question, but yeah, those are pretty standard variable names

though it really annoys me when I have to use j or k for indices. they're way too easy to mix up, especially i and j, so if I'm nesting loops I'll usually pick something more descriptive.

Q: Fastest way to sort 10 numbers? (numbers are 32 bit)

I'm solving a problem and it involves sorting 10 numbers (int32) very quickly. My application needs to sort 10 numbers millions of times as fast as possible. I'm sampling a data set of billions of elements and every time I need to pick 10 numbers out of it (simplified) and sort them (and make con...

Q: Naming conventions: camelCase versus underscore_case ? what are your thoughts about it?

I've been using underscore_case for about 2 years and I recently switched to camelCase because of the new job (been using the later one for about 2 months and I still think underscore_case is better suited for large projects where there are alot of programmers involved, mainly because the code is...

naming

Joe

@Almo wtf?

Almo

:D

I am reminded of Duff's device.

Pip

@TheMuffinCoder I use camelCase

TheMuffinCoder

lol so do i

Pip

18:42

TrueCamelCase for classes/methods/public properties

TheMuffinCoder

I think Java being the first language I learned influenced me the most

Pip

falseCamelCase for local variables

_camelCase for private things

Joe

@Almo im trying really hard to make sense of the logic because the sequence matters here... and im failing

TheMuffinCoder

NOoooooooooo

Pip

oh god Java

TheMuffinCoder

18:43

I hit remove accidently ; - ;

Pip

lol

you deserved it

Java does not belong in this chat

TheMuffinCoder

ProblemFactory.getLocalInstance().getPotatoChips().eat();

>:^)

Pip

NOO

Almo

@Joe heh it's the kind of think I look at, think "that's clever and probably works" but I don't bother trying to work out exactly how.

probably why my TIS scores aren't the best ;)

Icy Defiance

@Pip noooooo D:

underscores evil

TheMuffinCoder

18:44

Pip is JavaScript allowed in this chat? :3

Almo

underscores are evil

Joe

@Almo im sure theres reason for this logic here... i just cant see what it is

TheMuffinCoder

the root of all evil?

Joe

lol

Pip

I hate how Java developers use getFuckingRetardedMethodName

@IcyDefiance @Almo why?

TheMuffinCoder

18:44

getter setters shudders

Almo

@Joe looks like it's going through some sort algo, but hardwired for 10

Icy Defiance

@Pip 'cuz they're harder to type than letters

Almo

yeah an underscore is two keystrokes

TheMuffinCoder

Unless u bind it to a different key!!!

NOOOO my keyboard doesnt have the scroll key

D: i cant do it then ; - ;

Pip

All of my public properties also start with a capital which is two keystrokes as well

so it doesn't matter :P

TheMuffinCoder

18:46

so just do what java does!

Joe

@TheMuffinCoder i just installed a thermometer in my space bar... and I just type by raising and lowering my blood temperature at will

Icy Defiance

I just use the same thing for local/private variables, start with a lower case letter, never had a problem telling them apart. functions should generally be short enough to keep track of the variables in your head anyway.

TheMuffinCoder

@Joe LOOOOL

Martin_xs6

@TheMuffinCoder I also use camelCase. I think it's easier because pressing shift + letter is faster for me than shift + '_'

TheMuffinCoder

:D

Yep it is for me too!

But who needs variable names when u can just letters!

Icy Defiance

18:47

@TheMuffinCoder actually there are a bunch of tutorials about rebinding the caps lock key, since most people don't use it. you could bind it to an underscore. of course, then you can't rage on the internet as easily.

TheMuffinCoder

@IcyDefiance but the caps lock key holds a special place in our lives

Almo

CAPS LOCK IT'S LIKE THE CRUISE CONTROL FOR AWESOME

TheMuffinCoder

HOW ELSE CAN I DECLARE CONSTANTS

Icy Defiance

I know, cruise control for cool and all that, but some things you just have to let go

and constants are very seldom useful in C# anyway, because you can't assign a class instance to them. static readonly is usually what you want.

TheMuffinCoder

Why do people hate Java?

Almo

18:51

because it's annoying

honestly, my experience with Java is almost all on android.

I suspect the annoyance is android, not java itself

TheMuffinCoder

lol all this hate of Java is pushing me to go use Java

:3 come on Java lets make some secure high performance applications

Almo

here's what a cofounder of stackoverflow has to say about java-only CS schools

joelonsoftware.com/articles/ThePerilsofJavaSchools.html

interesting article

Icy Defiance

yeah Android is far, far worse than Java itself. Java is still fairly annoying though.

Pip

@Almo I actually usually just hold down shift

Almo

when I want to make the point hat I'm holding shift, I"LL TYPE STUFF LIKE THIS

caps lock doesn't turn the single quote into a double quote

TheMuffinCoder

18:54

Lol just wondering, is JavaScript hated this much too? :P

Icy Defiance

yes, at least for me, but in a different way

TheMuffinCoder

>:^) okay good

I want to main JavaScript

Icy Defiance

see, as a language, I don't hate Java, but I hate working with it because it takes forever to get anything done.

JavaScript is the other way around. I hate the language, but I don't hate working with it.

TheMuffinCoder

:3

Icy Defiance

at least until I have to debug something complicated in javascript

then I hate working with it

really hate this default IM sound

Martin Sojka

That's it; 15 tiles (broken into half-tiles in the picture) for the 2-terrain combination, 24 for the 3-terrain one and 6 for the three-terrain one - total 45.

TheMuffinCoder

i really like the one in window 10 tho

user92578

18:58

@MartinSojka Thanks for the image. All tough Im not quite sure if that'll help me with the masking tough

TheMuffinCoder

But it kills my ears when my sound is higher than 40

Icy Defiance

@TheMuffinCoder I'm going to guess that's because Java is a lot more popular for enterprise systems than in startups. That kind of system is generally more complicated and requires more expertise to work with, and the language is irrelevant.

TheMuffinCoder

@IcyDefiance ooo i see then

Icy Defiance

just a guess. can't say anything for sure.

TheMuffinCoder

lol thats what it see lower in the article xD

Large Corporations Have a Larger Influence

Kevin van der Velden

18:59

@MartinSojka nice

Icy Defiance

you should look up what COBOL programmers are paid

Kevin van der Velden

Question: are the lines a half-cell off (in both directions) in comparison with what is stored there?

TheMuffinCoder

@IcyDefiance :3 but they're so scarce

Kevin van der Velden

Or no wait

Icy Defiance

colleges don't teach COBOL anymore, and it's not used for anything new or exciting, so the people who are both able and willing to use it are literally dying off and large corporations who can't/won't upgrade are pretty desperate to find new programmers.

Martin Sojka

19:01

@KevinvanderVelden The trick here is that you don't typically use the four-terrain one if you can't help it. When the terrain on the "edges" is the same, you ignore what's in the "corner" and draw the two-terrain one. And also: This needs the same with the three other terrains as the main one (so another 45 at least).

(... and now I need to go back to the "easy" variant, with hexagons)

Kevin van der Velden

Well, my brain is already fried from the weekend, I'll just implement autocreating the 2 tile variant with a mask image and a source texture and then head to bed

Kevin van der Velden

19:30

Yay!

Pip

nice

Kevin van der Velden

Next up creating the relevant bits of the image @MartinSojka posted earlier

Kevin van der Velden

19:42

That was surprisingly easy:

Pip

huh

you want to open-source the code for that?

Noctrine

John Carmack's Son's game, made with racket - groups.google.com/forum/?hl=en#!topic/racket-users/yjRuIxypUQc

Kevin van der Velden

@Pip uuh probably

Pip

I meant now since I'm a bit bored atm :P

Kevin van der Velden

Heh sure

Everything is currently hardcoded but whatever

Pip

19:47

@Noctrine haha his son is at the same point in math that I am

and he's fucking 10

:/

Martin Sojka

@KevinvanderVelden The bottom three ones are actually not needed, I just included them for completeness' sake (in the original, they are variants on the "full tile" theme).

Kevin van der Velden

@MartinSojka aah I was wondering

I'll get rid of them then, it's just deleting 2 lines :D

Martin Sojka

The idea is that you have only the five "basic" in the texture and use UV coordinates to map the right half-tile to the right place. Saves you texture space in exchange for more vertices and faces, but in tile-based games, you don't typically have a vertex count which would make modern graphic cards sweat - not even on mobile devices.

Kevin van der Velden

True, well I'm outputting both the minimal and the full anyway so

@Pip github.com/KevinVDVelden/Utilities/tree/TextureTileGen

Pip

awesome, thanks

Kevin van der Velden

19:54

I pushed it to a different branch in my utilities repository because, meh

Pip

why didn't you include the layout thing?

Kevin van der Velden

Because it's trivial to make =p

Here:

Also, written in python3, no dependencies but what's included

Pip

coolcool

Kevin van der Velden

(Also if you want to use python2, I'm just using the fairly standard png.py file, which I used 2to3 on to get it to run under python3)

Pip

Nope, we're good with 3

I prefer it actually

Kevin van der Velden

20:02

Also if you want to work on the code, might I recommend this (shameless plug) utility? github.com/KevinVDVelden/Watchdog - It can automatically regenerate the output everything you edit the script

Pip

Pretty nice

I'll take a look :D

Kevin van der Velden

Sweet, and in the meantime I'll take a look at my eyelids

Cause I'm nearly falling asleep in my chair already

Pip

:D

Martin Sojka

The hex variant on the "cut up to reduce the amount of variants" idea is also relatively easy, thankfully:

Joe

20:21

@KevinvanderVelden any good reading anywhere on masking?

Jon

man, carmack's kid sucks

he says his game is available for download, but provides no link

1k3c.com/updates.html

Noctrine

He really needs to improve his website UX, yeah.

Jon

ok, so the links to his games are on his main page

Noctrine

Yeah

Jon

damn

angry face is an actual game

Noctrine

20:32

Yep

Jon

this kid is making games better than most people in here

i wonder how much code carmack does for him, lol

Noctrine

Fly is like Flappy Birds

He explains what he did and how he did it in places. (The son)

He seems pretty autonomous.

This is awesome though.

Now I get to show him how there is actually a cleaner 1000 line program hiding inside his 2000 line program.

Almo

@Ragdoll it appeals to a certain audience who like looking at past data to predict future behavior in a group of unknown actors

only takes about 4-5 players for it to become fun

and the rewards scale as the number of players increases

the fundamental problem is getting the right people exposed to it

Jovito

Why would you implement a list of entities as a linked list instead of an array in an ECS?

Ragdoll

22:32

faster removal

faster increased size

slower traversal, but overall more dynamic with the cost of more memory consumption

entities i imagine is a highly dynamic list
