You do your adventure ckd

Advent code

Pip

not yet, haven't had time

trying to get some kind of code working tonight

it's crunch time!

Icy Defiance

00:22

lol one liners are fun (advent of code spoiler) bitbucket.org/IcyDefiance/adventofcode/src/…

Icy Defiance

00:52

had to do it

Pip

lol

looking very nice Icy

Jon

:( I always log on with everyone is away

TheMuffinCoder

01:28

when* :3

MickLH

I actually am lurking, if you're wondering, I just have nothing to say

Pip

02:11

@IcyDefiance you lurking?

Icy Defiance

eww no. wtf do you think I am.

Pip

alright, cool

Any idea why your spritebatch wouldn't work?

Icy Defiance

'cuz it sucks probably

Pip

lol

Icy Defiance

nah today I just pasted it into my new framework as-is and it worked fine

Pip

02:14

now it errors on the shader?

wtf?

Icy Defiance

oh that one might be because of version differences

you'll want to remove the layout things and change the version line to 130

Pip

I did

no crashes then

but now it's doing this

Shader:

        static string vshader = @"#version 130
            in vec2 vertPos;
            in vec2 vertTexcoord;
            out vec2 texcoord;

            uniform vec2 pos, scale, texSize, tarSize;

            void main() {
                vec2 realPos = vec2(2 * pos.x / tarSize.x - 1, -2 * pos.y / tarSize.y + 1);
                vec2 realScale = vec2(texSize.x / tarSize.x, texSize.y / tarSize.y) * scale;

                texcoord = vertTexcoord;
                gl_Position = vec4(scale * vertPos, 0.0, 1.0);

Icy Defiance

okay when you get that error, it usually means the shader didn't compile properly. if you look in that output window again you should find the real error.

Pip

hm okay

Icy Defiance

tbh I should have thrown an exception when compiling instead of printing the error to console, but meh whatever

Pip

02:21

uuuh

no console output

Icy Defiance

Ctrl+Alt+O

if there's not an actual console then Console.WriteLine() prints there instead

Pip

ooh

nope, both shaders compile correctly

printed the compile status, but are 1

Icy Defiance

then...that is weird

the other reason you might get that exception is if the uniform really doesn't exist. either it isn't in the shader, or the gpu driver optimized it out.

Pip

hmm

Icy Defiance

but neither of those should be possible with that shader

Pip

02:26

yeah :/

Icy Defiance

I got nothing. Good luck! :D

Pip

thanks

only been working on this for like 3 hours :P

it's definitely something to do with the shader but I can't figure out what

Icy Defiance

oh, are you activating the shader before trying to set the uniform?

call shader.Use()

that's actually horrible design on my part

Pip

shader.Use();
GL.BindVertexArray(vao);
GL.ActiveTexture(TextureUnit.Texture0);
shader.SetUniform("pos", lastPos);
shader.SetUniform("texSize", lastTexSize);
shader.SetUniform("tarSize", lastTarSize);
shader.SetUniform("scale", lastScale);
shader.SetUniform("tint", lastTint);

Definitely calling it before then

Icy Defiance

jerk. you ruined my awesome theory.

Pip

02:31

lol

code is pretty identical to yours now

looking through for differences

there's one difference

List<TexturePositionMap> toDraw = new List<TexturePositionMap>();

that's in yours. Mine is:

List<Sprite> toDraw = new List<Sprite>();

    struct TexturePositionMap
    {
        public Texture Texture;
        public Vector2 Position;
        public Vector2 Scale;
        public Vector4 Tint;
    }

Icy Defiance

oh yeah why does that Sprite class even exist in my code...

weird

Pip

class Sprite
{
    public Texture Texture;
    public Vector2 Position;
    public Vector2 Scale = Vector2.One;
    public Vector4 Tint = Vector4.One;
}

the Sprite class is mine

Icy Defiance

yeah but I had one too

I might have made it for my UI stuff and forgot the TexturePositionMap existed

Pip

sooooo... no difference between the TexturePositionMap and my Sprite

Icy Defiance

yeah that wouldn't cause the exception anyway

Pip

02:35

except... struct vs class? meh, yeah

I also removed all of those Draw overloads

and made it Add(Sprite)

and changed Flush to Draw

but none of that should make a difference

hastebin.com/ofajuzeyal.coffee

hastebin.com/ideqefikux.avrasm

spritebatch and shader classes

        protected override void OnLoad(EventArgs e)
        {
            base.OnLoad(e);

            spriteBatch = new SpriteBatch();
            sprite = new Sprite() { Texture = new Texture(new Bitmap(@"test.png")), Position = Vector2.Zero };

            GL.ClearColor(Color.CornflowerBlue);
            GL.PointSize(5f);
            GL.Enable(EnableCap.DepthTest);
        }

        protected override void OnRenderFrame(FrameEventArgs e)
        {
            base.OnRenderFrame(e);
            GL.Viewport(0, 0, Width, Height);

part of GameWindow

Any ideas, @IcyDefiance?

I can send the whole project if you want :P

(Not that you want to, ofc. Being a ~~little~~ lot frustrated atm :P)

Icy Defiance

go ahead. I'm gonna bet it just works on my computer. :P

Pip

alright

be warned: super messy file system right now because I'm refactoring and actually getting things to work

Icy Defiance

which would actually be awesome for me, because when you find a solution to the problem, you can tell me and I can increase compatibility

Pip

awesome

drive.google.com/file/d/0B1R8O3E_hQmoc0p3SWtNQ1UxcUE/…

@IcyDefiance here you go

everything should be in the Liyr project

Icy Defiance

02:55

oh, yeah, the gpu did optimize out that variable, because you changed the output line

gl_Position = vec4(realScale * vertPos + realPos, 0.0, 1.0);
vs
gl_Position = vec4(scale * vertPos, 0.0, 1.0);

Pip

oh fuck really

god damnit :P

So it was totally my fault

awesome :P

Icy Defiance

also you can change the first part of the shader to this, just because it looks nicer

vec2 realPos = vec2(2, -2) * pos / tarSize + vec2(-1, 1);
vec2 realScale = texSize / tarSize * scale;

I can't let my ugly code just run wild like that

Pip

same error!

        static string vshader = @"#version 130
            in vec2 vertPos;
            in vec2 vertTexcoord;
            out vec2 texcoord;

            uniform vec2 pos, scale, texSize, tarSize;

            void main() {
                vec2 realPos = vec2(2, -2) * pos / tarSize + vec2(-1, 1);
                vec2 realScale = texSize / tarSize * scale;

                texcoord = vertTexcoord;
                gl_Position = vec4(scale * vertPos, 0.0, 1.0);
            }";

Icy Defiance

dude, you didn't change that last line

Pip

oh fuck

thanks

Fuzzy Logic

03:02

@IcyDefiance you should also use parentheses to be more explicit, if you are going for cleanliness :)

Icy Defiance

unnecessary parentheses annoy me. just learn the order of operations instead. :P

Pip

alright, running now

Icy Defiance

not my fault people don't know that shit

Pip

no sprite still though

Fuzzy Logic

I came from C, so I learned not to trust operator precedence

Icy Defiance

03:03

oh? is it not reliable there?

Fuzzy Logic

mostly, but it's not part of the language spec so compilers are free to do it however they want.. don't think it's ever an issue for */ or +- though

Pip

@IcyDefiance any guess why there's no sprite

Icy Defiance

"The C language standard doesn't specify operator precedence. It specifies the language grammar, and the precedence table is derived from it to simplify understanding."

wow

Fuzzy Logic

it can be an issue when dealing with */ and &|

sometimes bitwise is handled first, sometimes later

Icy Defiance

@Pip Game.TargetSize isn't being set anywhere. you want to just make that equal to the window size.

Fuzzy Logic

03:11

regardless, as a matter of habit, I learned to be explicit just to clarify intent

Pip

oh damn

Icy Defiance

you could just use the window size directly, but once you start using framebuffers that will change

#FuzzyLogic yeah operator precedence is defined in the C# standard, and as far as math goes it just makes sense. redundant parenthesis might be nice for clarity with unusual stuff, like bitwise operations, but for the most part it's just clutter.

lol actually that particular code is glsl, not C#. I wonder how it's defined there...

Pip

boom!

It works, thank you so much Icy

Icy Defiance

ah yep, it's defined in the glsl spec too, page 7. opengl.org/registry/doc/GLSLangSpec.Full.1.20.8.pdf

Pip

legit!

Icy Defiance

03:16

btw if you're tempted to start on text support next, my SpriteFont class on bitbucket is totally broken. don't use it. :P

Pip

I have a text renderer using System.Drawing for right now

works okay

Will need replaced later

there's some code sitting around in those projects somewhere if you want to see

Icy Defiance

nah I think I'm done with code for tonight

Pip

I think I am as well as soon as I verify that the orientation of the image is correct

thanks for the help! You saved me a lot of frustration :P

Aidan Mueller

06:54

This is annoying. The Ukrainian И makes a I sound as in "bit". But for whatever reason, it is transliterated to a Y.

It does have slight resemblance to E and Y, but not as much as a plain old Й.

Aidan Mueller

07:42

Imagine if Wikipedia met their goal in an hour.

That could be a movie.

"The time when Wikipedia met their fund raising goal in an hour".

Almo

08:21

i give them $5 a year, about

Martin Sojka

09:17

@AidanMueller Transliteration is not transcription. The focus is on being able to tell what the original spelling looked like, not how it sounded.

(See for example "你好" as spoken in Mandarin being transliterated with pinyin to ni3hao3).

Jon

10:36

YAAAAAAAAAAAAAAAAAAAAAAAAAAWN

Chris

my power supply died

rip

dunno how long this RMA is gonna take lol

Jon

what brand?

Chris

Corsair, HX650W
Almost 6 years old now, has a 7-year warranty heh

Jon

lol funny

Corsair is actually amazing when it comes to customer support

they sent me a ram chip replacement like 5 years later, didn't have to send them the broken one

Chris

nice
I'm going through the retailer I bought it from, but they're the best computer shop in the country. Hopefully they'll just gimme a new one if I return the old, not sure what their RMA process is

Jon

10:58

after 6 years.. you usually have to go through manufacturer

Day 3 advent -- puzzle 1 easy peasy.

I used a dictionary :)

shit, part 2 was easy if you used dicts

now I gotta wait en entire day for more

Jon

Definitely Captain Planet

Jon

12:21

Anyone here ever develop a point and clicker?

Wardy

12:54

like every web app ever you mean?

Jon

13:11

game.

Almo

14:41

@Jon not me

i made a verb/noun text adventure once

Jon

cool

I'm currently talking with a guy about making a point and click puzzle style game

Jon

15:13

Man.

I think I found an artist.

Almo

try working at a game company and not caring about the new star wars movie

Jon

hehe

Almo

after attak of the clones, i only saw III because I wanted to see what Lucas would do with his power. but now I just don't give a shit

Disney

Jon

15:31

i hope the reveal is jar jar as the sith lord

Almo

just a big dollar sign would be sufficient

MickLH

My roommates are so pissed that I'm back on my medication lol

Jon

you have roomates?

those poor bastards.

MickLH

lol

Especially when you consider I sleep almost exactly 6 hours and listen to music and dance when I'm feeling OK about life

1am - 2am => subwoofer calms down

7am - 8am => subwoofer back on

and it's not "brrrrrrr" either... it's "WOOOOOOOM WUWUWUWUWUW"

They should be awake and ready for work anyways at this hour

I'm joking, just in case anyone is angrily fuming like: "What a dick."

I remembered it's 7am, and used headphones instead today

But seriously, who wouldn't want to wake up to this: soundcloud.com/destroid/…

Jon

15:48

lol

Wardy

@MickLH if you woke me up with that I would beat your door down and smash your sound system

MickLH

:D

Wardy

I used to live next to someone like that, they soon learned that it's not wise to do such things when i'm trying to think too

it doesn't bode well for them

MickLH

That's why we're not neighbors, people always ask what happens when an unstoppable force meets an immovable object

The answer is: They don't.

Wardy

completely agree (scary thought, we actually agree on something)

MickLH

15:51

Lol actually thinking about it for a bit, I am coming to the idea that we'd have some kind of physical fight and eventually end up at the bar

God I have to listen to this song again, I love the fucking duck sound drop so much

quack- quack- quack- quack.

Almo

16:49

Ok, the Marshal badge encourages behavior you don't want. I'm going to quit answering questions on GDSE until I get it, because if I hit 3k rep, it's suddenly really hard to get helpful flags.

user4704

@Almo How much is it worth it to you for me to NOT give you a 500 point bounty then? :)

Almo

hahah :D

user4704

I need 113 more spammers before I can get marshal.

Almo

that's quite a few

user4704

Yeah.

Almo

16:51

i think it's another 2-3 weeks of bad questions to get me marshal

well maybe 2 months still it's not long

user4704

We used to use flags for mod communication on "should we do X with this?" ages ago, but then we found a better way

Almo

I was thinking that maybe successful close votes counting toward it would help, but then that would encourage excessive closing.

user4704

So I'm sitting at 387 flags and the only way that number goes up is if I use a spam flag.

Almo

I haven't found a workable solution to this, beyond maybe reducing the req for the badge

user4704

OTOH I have ten gold badges now, and that's a nice round number

Almo

16:52

heheh cool :)

i have 6 on SO, including Unsung Hero :D

that one took years to get

user4704

Yeah I'll probably never get that one either.

Almo

It's hard to get UH on GDSE because it's a smaller community, and good answers (like yours) just attract upvotes

on SO there's so much traffic it's easy for your answer to go unnoticed if it's instantly accepted and not upvoted.

Noctrine

Swift is open source : github.com/apple/swift

user4704

That's true.

user4704

@Noctrine Ah, that finally happened?

user4704

16:58

Cool

Almo

the badges don't all scale for the various-sized communities

Noctrine

Just a little while ago, also swift.org

user4704

@Almo Yeah. I try not to think about them too much.

Almo

:)

user4704

I don't like "achievements" and similar mechanics.

Almo

17:02

I only worry about the ones that are attainable

Shit like Wipeout HD "Place 1st vs expert AI on all tracks forward and backward"... fuck that

i can't even place top 3 vs normal AI.

Q: Should I tell the player he has no chance to complete the level?

Suppose that a player has reached a point where he has absolutely no chance to complete the current level, and he must restart it and try again. Should I notify him that he will gain nothing by continuing the level and he needs to restart? If so, how should I tell him that? Would a message box ...

user4704

I wish I could add custom post notices :|

Almo

what you mean?

user4704

Hang on

user4704

Also, in addition to the "explanation and context" post notice, please try to post answers that take a position and offer a defense of that position. It's what makes "good subjective" questions like this useful; don't just post a wishy-washy "I think it could go either way" answer without explaining why. — Josh Petrie ♦ 17 secs ago

user4704

17:09

That's why.

Noctrine

We can't add custom notices anymore?

Or was that just in bounties?

I suppose it could be edited in.

user4704

Just bounties I think.

user4704

We can't modify the notices at all, as far as I know.

Almo

17:58

oh right

MickLH

I kinda hate Swift completely, it feels half-assed to me.

The only way I've found it better than any language I like, is the nested comments

But I'm probably biased, because my parser does nested comments. I hate trying to comment out a block for a quick test, only to find that there's a comment in your comment, ending the comment early and ruining the "quick" part of the quick test

Jon

What do you guys think about an interactive story "game"

user4704

What about it?

Lasse

@Jon amazon.com/Muppet-Treasure-Island-PC/dp/B0015P9Z4G

this one was a good game

at least it was back then

Noctrine

@Jon What do you mean by interactive story?

Jon

18:06

I am currently discussing ideas with someone.

The concept is that you are inside a characters dream

and you can interact with the scene, instaed of the character

to mess with him

The character would act upon the change in scene.. or whatever.

user4704

Okay.

Noctrine

We need spoiler tags : The end of that one movie about relativity from the protags perspective?

I think it could be interesting, but it sounds more like a desktop toy at this point.

Or like, the sims with max autonomy?

Jon

It would be more of an interactive film

Than a game.

Noctrine

So the character that you are watching already has a purpose -and you have to choose to help them to it?

Jon

exactly.

Noctrine

18:16

I'd play it. - If only for the novelty

user4704

There's a lot of room for how you build the "gameplay" in those sorts of games. I think they can be interesting if done well.

user4704

You can go too far though and then it becomes more of an interactive film rather than a "game" (largely distinguished, in my mind, by the inability to make meaningful choices)

Jon

this game looks insane

11 Minutes of Cuphead Gameplay

►

Icy Defiance

I'm not sure being an interactive film is bad. I avoid most point and click games for that reason, but limbo was completely linear and that was still pretty cool.

not sure where I'd draw the line

Noctrine

@Jon This is the game that really pushed me towards wanting an xbox.

Jon

18:30

it is very pretty looking.. not sure if it will be fun, but it sure looks good

user4704

I woudln't say it's bad to be an interactive film. Just not my thing.

Almo

@Jon personally they don't tend to interest me, unless it's really involving like Heavy Rain. I liked that for some reason.

@IcyDefiance limbo had physics puzzles. not interactive film.

Jon

SHAUN!!!

Heavy Rain Glitch

►

Almo

Some of the choices in that game were seriously agonizing.

Icy Defiance

yeah it had puzzles, but those puzzles only had one solution

Almo

18:37

that's doesn't make it an interactive film in my opinion

user4704

@Jon This was all I thought of every time my character was whiny about his kid in FO4.

Jon

haha me too

there is a mod that replaces mini-nukes with babies

And there is actually a heavy rain mod for fo4

FALLOUT 4 - CRAZIEST MODS SO FAR! (#1)

I need a "turn off clipping dammit" mod for building.

(and a related, "turn off snapping dammit" option)

user4704

I spent too long carefully trying to place junk fence and half-width walls to make a reasonable looking perimeter fence around part of my fortess of solitude

user4704

18:47

without leaving derpy holes

Jon

19:00

yeah, the build mode is really bad.

in a year or so, the really good mods will be coming out

This baby mod for the mini-nuke is hilarious ... the baby just flies towards the enemy and explodes. hahahaha

exploding baby.. classic.

Q: Nested Ternary Implicit type Conversion issue: Type of conditional expression cannot be determined because there is no implicit conversion between

I have used nested ternaries in the past quite frequently with c#. After I introduced An event handler, as the assignment operation, I was presented with the error: "Type of conditional expression cannot be determined because there is no implicit conversion between 'void' and 'void'" Here are tw...

c# ternary-operator

user4704

My eyes!

Almo

hahah :)

Pip

Ey

I have used nested ternaries before

not often because they get messy

but a couple of times

@MickLH this. so frustrating sometimes

@IcyDefiance finally got textures to draw correctly

I have no idea what I changed but now they are no longer flipping over the y=x diagonal

Icy Defiance

20:46

heh, I've written a ternary chain worse than the one in that question

only once though, and it evolved over a month of new requirements. it was pretty simple at first.

the good thing is those are pretty easy to refactor into if statements. took under 30 minutes for mine.

Pip

yeah, since they're just if/else statements with a "return"

Icy Defiance

the one in that question would take like 5 minutes of typing, not much thinking

bazola

21:06

hey all, can anyone give feedback on the physics of my new prototype? its the first time I've tried doing something like this: pixelpocalypse.com/wormy2d

Almo

no, connection timed out

bazola

its working for others so it should be a good link

Icy Defiance

yeah worked for me. physics seem normal. you probably used box2d for it?

bazola

yeah its box2d

Fuzzy Logic

21:36

gah! want to tell that ternary guy to just stop programming.

haha, embedded assignments no less
