murder? I do admit, the character trope of a guy in a suit with a cross necklace blowing things up and then saying "Amen" is a pretty cool one.

Trigun had something like that I think.

Noctrine

Hellsing :\

Icy Defiance

ooh yeah that's what I was thinking of

even better

hasherr

I now pronounce you Man and Knife.

explosion

Icy Defiance

I saw the original Hellsing, and apparently Ultimate is a lot better, but I can't make myself watch the same story again. :/

Noctrine

There was the one dude in Trigun but Alexander Anderson is that trope personified

Ultimate is better in all things

Alex M.

21:01

I'm pretty sure Wolfwood wasn't a true priest

Noctrine

The story is the proper story, not the anime type one

Alex M.

also his storyline is different in the anime from the manga

Noctrine

So watch it :p

Grey

@AlexM. Do you know of any 2D tile editors?

for unity

Alex M.

hmm

Grey

21:02

Good ones at that lol

Noctrine

@Grey Favorite Pixel Art tool is Pyxel

Alex M.

tile editors, as in..?

hasherr

Listening to Obama's Spotify playlists...

This guy has the music tastes of a 14 year old girl.

Grey

@AlexM. Creating Levels Via Scene View Unity. I'm sure there is an add-on.

Alex M.

yeah, it's called Unity 4.3 :D

Grey

21:03

lol

Lasse

I have used Tiled in the past, but I don't know if it's actually any good

Alex M.

you guys recommend programs that export the map data in a format unity doesn't recognize :)

Lasse

unity can't read xml?

too bad

Noctrine

I meant actually doing art, not making maps :\

Alex M.

well it reads what you tell it to read

but I'm sure Grey wouldn't write his own map parser

Grey

21:05

@AlexM. easy

I'd just have to mess around with the Z for depth

Alex M.

why would you do that

when Unity 4.3 lets you build 2D stuff in the scene view :\

Grey

@AlexM. I would do that if Tiled was my only option

@AlexM. yus

Icy Defiance

pretty sure Linq for XML makes parsing easy. not fast, but it's not like he'll load something every frame.

can C# for Unity use Linq?

Vaughan Hilts

yea.

Lasse

there are easier ways to read xml

like serialization

Icy Defiance

21:06

could be. I've only done it once, and I just used the first hit on google.

Vaughan Hilts

Easiest way is use xsd

Lasse

you just need to create a serializable data structure which fits the xml

Alex M.

guys

Vaughan Hilts

to generate a class defintion, and then just deserailize it

Alex M.

why would you read an xml and build the level through code

WHEN YOU CAN USE THE EDITOR

Vaughan Hilts

21:07

@AlexM. BECAUSE YOU'RE HARDCORE, DUH.

Icy Defiance

because he didn't seem to want to use the editor

also, it seemed like a fun problem

hasherr

omg so hrdcr

Vaughan Hilts

like I know, right?

SO L33T

Icy Defiance

your face is a hrdcr

Alex M.

@IcyDefiance he wanted to use the editor

but he didn't know of a plugin

that's what he asked for :D

Vaughan Hilts

21:09

HARD. CORE.

Lasse

that one line slipped thru my hawk eyes

or past?

idk vOv

Icy Defiance

@Lasse no, you're not a hawk either. you're a freaking penguin. a very confused penguin, but nevertheless, a penguin.

Lasse

hey how do I quote, I've asked this before and didn't get an answer

Icy Defiance

stop trying to be other birds, dammit!

click on the arrow next to the message and drag it to the text box

Lasse

21:11

OH

that never crossed my mind

Vaughan Hilts

Nope.

Didn't work.

Vaughan Hilts

@Lasse Maybe?

Lasse

it has to be on it's own

Icy Defiance

@VaughanHilts that would work too if you didn't type anything else there

Well, that's just lame.

Icy Defiance

it's oneboxxed. same as images or whatever else.

Noctrine

Hrm, my blueprints don't look government-y enough

Alex M.

@Grey if you don't want to 4.3 you can also go back to orthello

Vaughan Hilts

@Noctrine I demand you fix this madness.

Grey

21:12

@AlexM. 4.3'ing

LOL

see's orthello's name

withers

Lasse

@Noctrine add something completly unhelpful data in there, should get it sorted

Vaughan Hilts

is Unity 4.3 out yet?

Noctrine

Yep

Lasse

yes it is

Grey

@VaughanHilts No, it's not out till 2014

Alex M.

21:13

Orthello is the only framework which caused me issues because it used singletons

Grey

:>

Alex M.

it is also the first thing overall that caused me issues because it used singletons

I still don't hate on singletons though

Vaughan Hilts

Woo, looks like it is.

Icy Defiance

I'll hate on singletons! :D

Vaughan Hilts

I'll have to take a look next weekend, bleck.

Icy Defiance

21:14

actually no I won't. I just haven't found a use for them yet.

Alex M.

honestly, if I had to build something to hold references to all of my entities in a game, I'd make it a singleton :\

Vaughan Hilts

Then you end up GodManager

Alex M.

so I could just ActiveGameEntities.FindWithID(someID);

Lasse

that's what static classes are for in C#

Alex M.

it would be weird to not use static classes for a singleton, don't you think?

Lasse

21:16

singleton is not a static class

Vaughan Hilts

Fuu, building a calculator is going to take like 8 hours

Fucking Swing

Lasse

Q: Why choose a static class over a singleton implementation?

The Static Vs. Singleton question has been discussed before many times in SO. However, all the answers pointed out the many advantages of a singleton. My question is - what are the advantages of a static class over a singleton? Why not simply choose a singleton every time?

Alex M.

I can't think of a way to enforce the presence of a single instance of an object without static classes

Lasse

static properties does not make the class static

Vaughan Hilts

I don't think global is evil applies sometimes.. :)

(Maybe I'm just lazy.)

Alex M.

21:18

@Lasse static classes do make the classes static though

a singleton is an architectural pattern

Lasse

oh yes, but if you declare a class static, you can't create a singleton out of it

Alex M.

you use staticness for it

@Lasse only if you abide to the Class.Instance recipe

Lasse

you want to be right so hard that you can't say someone else is right?

Alex M.

I'm not saying you're wrong

Lasse

what are you saying then?

Grey

21:21

I'm saying you are incorrect

big difference

:>

Alex M.

if my entity manager was a "static class"

Lasse

if it was a static class, it wouldn't be a singleton at all

Alex M.

did it even matter or differ that much in concept from the singleton, enough to not take the same things it involves into consideration?

Lasse

it would work like one, but it would be completly different thing from architecture viewpoint

Alex M.

I think it still behaves like a singleton in all cases except the class doesn't hold a static instance of the singleton

and I just treat the static class as a singleton

if I were to talk to someone about the OT static class and the problems it caused to me, I'd most likely refer to it as singleton

because that's what it is

and it makes the listener understand what I'm talking about

Lasse

21:24

there is a difference

Alex M.

nitpicking usually doesn't help the discussions in most cases

Lasse

you could destroy the singleton and create a new one, but you can't do that with static class

Alex M.

then you need a different approach to the singleton implementation

Lasse

and that alone is a reason enough to keep the two terms separate

Alex M.

I don't think it is, honestly :\

Lasse

21:26

and why would I need a different approach for that?

Alex M.

because mine doesn't cover your use case?

isn't that what you're saying?

Lasse

if I have game states implemented as singletons (a bad example in real world, I know but let's just ignore that fact) it would be wise to be able to destroy the unused state if it's not used any more with it's current data

Alex M.

only the state machine would be a singleton if I were to drive that design and had to use singletons

Lasse

as I said that was a bad example in real world, but the only one I was able to think of so quickly

Alex M.

StateMachine<Entity>
{
	State CurrentState;
}

State
{
	OnEnter(Entity target);
	OnUpdate(Entity target);
	OnExit(Entity target);
}

this is how I usually implement FSMs

Lasse

21:28

and your code just does not have anything to do with any of this

Alex M.

yes

what I'm showing to you is why you don't need to destroy states

Noctrine

What's cooler

Alex M.

ice cream!

Lasse

space

Noctrine

Top Secret Government Facility in the Middle of Nowhere, or Top Secret Government Facility in a city.

Alex M.

21:30

I dunno lassie, it seems to me like you're not saying anything here :\

just barking around

Lasse

it seems to me the same thing about you :(

Alex M.

'cept I'm talking and not barking :D

Icy Defiance

@Noctrine personally I find it cooler in a city. there seems to be so much more you can do with it.

Lasse

@AlexM. now let's make an argument out of that then

Icy Defiance

also since people recognize places in a city, it's a bit more of a surprise.

Alex M.

21:31

@Lasse I'm afraid I don't have the time

but you can go on alone

Lasse

argument always takes two

if it doesn't, time to take the pills

and suddendly, chrome is not able to kill tabs

wtf

hasherr

This just happened less than 100 miles from me.

Icy Defiance

ooh

Noctrine

Giant Robots and Jets launching out of a city is highly implausible though :\

hasherr

Yeah. I think the worst just passed me.

Our power went out, we didn't get hardly any at all.

Icy Defiance

21:37

@Noctrine yeah, at least if it's supposed to happen on a regular basis.

Alex M.

@hasherr :O

Lasse

@hasherr There was a storm called "Eino" in finland just this weekend, and it's still going on

hasherr

@Lasse #WeWillRecover

Icy Defiance

the destruction! the horror!

Alex M.

►

hasherr

21:38

lol

Lasse

almost 10k residences are without electricity after this Eino storm

hasherr

@AlexM. Clicked on the video, immediately closed it. I will not get fatter.

Alex M.

that was a mistake

because it's not what you think it is

Lasse

was that tuna?

Vaughan Hilts

.. if anyone would like to just donate that chocolate to me instead.

Lasse

21:42

would you like the tuna and the bunny with that too?

Icy Defiance

bunny really didn't want to die

poor bunny

Vaughan Hilts

xD

hasherr

www.youtube.com/watch?v=LB871SVYMhI

I just... I just want to know WHY.

I could use Byte's help...

Lasse

@hasherr I'd reply to that but the video is in finnish and has no subtitles

hasherr

lol

I crack up everytime he says 'Jimmy your mom is ded'

flips table in anger

Why isn't my spritesheet working!

flips table in anger

Lasse

21:53

is the table now actually right side up?

as in standing correctly

hasherr

No.

It's glitching up again.

Lasse

but if you flipped the table two times, how come it's wrong?

hasherr

idk.

        playerSprite.bind();
        glBegin(GL_QUADS);
            glTexCoord2f(0f, 0f);
            glVertex2d(pos.x, pos.y);

            glTexCoord2f(128.0f, 0.0f);
            glVertex2d(pos.x + playerSprite.getImageWidth(), pos.y);

            glTexCoord2f(128.0f, 64.0f);
            glVertex2d(pos.x + playerSprite.getImageWidth(), pos.y + playerSprite.getImageHeight());

            glTexCoord2f(0f, 64.0f);
            glVertex2d(pos.x, pos.y + playerSprite.getImageHeight());
        glEnd();

Vaughan Hilts

See, this is why you don't work in raw OpenGL.

hasherr

Lasse

21:56

why texcoord like that?

hasherr

To assign which part of the spritesheet that I need.

I must be doing it wrong though.

Lasse

show the matrix, I see no problem in that code

hasherr

The matrix?

Vaughan Hilts

Your view matrix

Icy Defiance

if he's doing 2D with some library, he probably didn't make one himself

hasherr

21:58

I don't know what that means.

Vaughan Hilts

Looks like like jwgl

i.e: raw opengl

hasherr

Okay.

Lasse

@VaughanHilts it's not wrong to use raw opengl

Vaughan Hilts

Of course it isn't. :)

Icy Defiance

yeah it does look like that

Vaughan Hilts

21:59

(But it is painful for a beginner..)

@hasherr have you outputted the values you get from pos and sprite size?

Vaughan Hilts

I still think @IcyDefiance is a sadist. :)

Or at least, masochistic.

Icy Defiance

uhh, those would be opposites
