Space is beautiful :D

NaCl

Space is boring emptyness with some deadly photons

TheMuffinCoder

But what about all the deadly prokaryotic bacteria in nature?

NaCl

Nature is scary

Guys I finally did it

I finally made something in illustrator that looks awesome

My entire game is going to have this art style now

It's so much less work then making entire 3D models in blender just to render the top part

Pip

2:09 AM

@MickLH you know that embedded dll thing I did?

Well, it just broke for no reason that I can tell between two compiles

cleans and restarts don't help

Ideas?

MickLH

@Pip Main idea: Solve the deeper problem with an installer

Pip

That's annoying though L

PearsonArtPhoto

Just need to get over the last bump...

I've been working towards something pretty much all week, I just need a little bit more motivation to finish it...

Unfortunately I think my motivation already went to bed.

Pip

JUST DO IT!

Did that work?

@TheMuffinCoder I'm wondering... is that a dress? an spaceship? or a weapon?

don't get me wrong... it looks awesome, I just don't know what it is?

Blue Bug

@Ali.S He is making multiplayer top down space ship game, somewhat like Agario, if I remember correctly.

Ali.S

right? so it can't be a dress... is it an spaceship or a weapon on an spaceship?

7:54 AM

Good morning!

Blue Bug

What's new typpi!

user92578

parents left for a weekend trip, I've got no-distraction dev time for like 34 hours

user92578

trying to come up with tasks for today and tomorrow

user92578

how are you?

Blue Bug

trying to render with vertex array object! @Tyyppi_77

user92578

8:03 AM

cool!

Blue Bug

Sounds exciting! I want to make game too!

sn0k3

8:53 AM

Hi

Blue Bug

HI! @sn0k3

user92578

9:18 AM

Heya

user92578

10:14 AM

Finally! I can now reliably reproduce an annoying bug I've had for a long time

user92578

Still not sure what's the actual cause, but this is already so much progress

user92578

10:29 AM

GOT IT!

user92578

WOOOO HOOO

user92578

Now I'm gonna go make myself some pasta

Jon

10:51 AM

Gonna hatch a plan to get breakfast made for me

user92578

11:33 AM

damn I can't cook for real

user92578

The kitchen is a big mess and the pasta was bland

Kevin van der Velden

11:53 AM

Solution: Add more chili

user92578

some pepper would've probably done too

user92578

luckily tomorrow I can just put stuff into the oven, no actual cooking required

Blue Bug

12:14 PM

@Tyyppi_77 I fixed my bug!

user92578

nice, me too!

Blue Bug

12:25 PM

bug: j.gifs.com/68Nr79.gif

fixed it! YES!

user92578

I don't know what I'm looking at but looks cool

Blue Bug

shadow shadow shadow!

shadow map! @Tyyppi_77!

user92578

you don't need to ping me everytime

Blue Bug

I know. But it is fun to imagine the ping sound you will hear.

user92578

you should add some basic directional light so the objects could be more easily recognizable

Blue Bug

12:31 PM

ping! ping! ping! ping! ping! pi...

user92578

and if you ping me one more time I'm turning the sounds off.

Blue Bug

:*(

user92578

I'm here, and I will be looking at the messages

Jon

I am here.

Blue Bug

I did it jon!

Jon

12:34 PM

Had to make my own breakfast

Did what? Get a girlfriend?

Blue Bug

um... no... shadow mapping I mean...

Who needs a human companionship when you have a computer.

Jon

Looks good.

And strange

user92578

seriously, add a hardcoded directional light

user92578

that ambient is hurting my eyes

Blue Bug

I am an independent sentient being who ain't no need man.

Jon

12:38 PM

So u into men?

Blue Bug

I will leave that question as a mystery because a girls gotta have her secret.

Tyyppi_77, I think the color red is easiest color to work with! it makes spotting it, visual reception process easier!

user92578

Sure, but it's all just a big lump of red

user92578

Directional light is like one line of code to add

Blue Bug

I will!... um... very soon!! soon...

Leggy7

good afternoon guys

and girls

user92578

12:49 PM

hi!

Leggy7

I'm ready to insert weapons in the game!

good work to me :)

user92578

nice!

user92578

I'm working on adding variety to my weapons too

Leggy7

weapons are a great thing, aren't they?

:)

user92578

yeah

Leggy7

12:52 PM

customers like weapons

we like customers

user92578

I realized earlier today that for a game called GunHero my guns are really lame

Leggy7

we like weapons

what do you mean?

user92578

well the (too few) guns I have are too similar

user92578

I noticed that I never pickup any guns, I just use the SMG I start with

Leggy7

balancing weapons and making them versatile is very important I guess

In my game they will be mostly something cool to get

not so important thay they exist

but cool

user92578

12:59 PM

user92578

Lots of work still needed but I'm getting started

sn0k3

That was your first game, wasn't it?

user92578

Yeah this is my first real project I'm working on

sn0k3

real?

user92578

serious

sn0k3

1:05 PM

oh

:D

Are you full time indie or just hobbyist?

user92578

hobbyist, but that it's summer kinda fulltime

sn0k3

Hm, these days you said that you don't touch that much SDL code in your game..Well, what does actually your framework includes?

I mean how did you structured it?

Blue Bug

have u played Metal Slug Typpi?

user92578

I really only touch SDL when I respond to input, as it felt like a waste of time masking the events away

user92578

I've built my layers for rendering (Sprite classes and such) and then the whole entity/level structure, so I just know my systems use SDL behind the scenes

Blue Bug

1:08 PM

Metal Slug is like father of 2d gun shooting side scrolling genre

sn0k3

Because maybe I will make my game in SDL, not in Java with it's standart library ( I am currently using it )

user92578

Basically all the features I'm implementing are made on a higher level, and SDL is the lowest level I touch

user92578

SDL is kinda good, all tough I'm a little sad that it doesn't support shaders

sn0k3

SFML supports shaders

user92578

If you've never touched C++ before, it's an okay library to get started with, all though C++ ain't easy

user92578

1:09 PM

Yeah SFML does support shaders

user92578

Were I to start from nothing today, I would probably pick SFML

sn0k3

I've done 1-2 games in C++ using SDL, but I'm not sure was SDL 2 released then or I've used 1.2

Blue Bug

take a look at Metal Slug. They have fantastic guns that can be an inspirtation

sn0k3

I've done tests with SDL 2

user92578

@BlueBug I will

sn0k3

1:15 PM

Have you followed any tutorials in SDL?

or you have just read the documentation

Jon

did mozart read tutorials on how to compose?

Metal Slug was super amazing at the time -- the pixel art in that game is top notch stuff

sn0k3

Jon, I've just asked him if he knows some good tutorials on SDL..

Jon

I was joking -- being born knowing how to code isn't really a thing, lol

Leggy7

like the bad joke eel now we have to good joke jon

user92578

I've just read the documentation, but Lazy Foo's tutorials are kinda nice

sn0k3

1:20 PM

okay

ty

:)

Jon

I pity the foo.

ok guys, my test build is almost ready - are you guys ready to lower yourselves to the level of testers?

Leggy7

speaking about gorb?

Jon

yeh

Leggy7

If I'm still a pc will be a pleasure

Jon

i am looking for android testers

tablet or phone

Leggy7

1:28 PM

I can try it on my phone

browser or app?

user92578

m_BulletSpeed = TVector2(6.0f * (type == EEntityBulletType::PLAYER ? 1.0f : (bossBullet ? 1.0f : 0.75f)), 1.0f);

user92578

Look at this fucking shit

Leggy7

what's up?

don't you like your shit?

try eating mine :)

Jon

it will be an app..

Leggy7

if (!busy && gc.GetCurrentState() == GameState.FIGHT && cmd.CompareTo(string.Empty) != 0)

Jon

1:31 PM

you would need dev options on your phone I think, to install unsigned apps...

tap about 5 times

Leggy7

i do know, kk

I think it is already enabled

Jon

or the version number actually

user92578

yeah I've got an Android phone too, already in dev mode for Cognizer

Jon

good luck getting 143 in 9 hahahahaha

user92578

what?

Jon

1:35 PM

gorb slang

MickLH

1:46 PM

@Jon Metal Slug is still really fun

Jon

getting shit done when a level doesnt work in your engine:

if (ApplicationData.CurrentLevel == 145) {

MickLH

^ #CodingIsNotAlgorithmDesign ?

Jon

heheh

user92578

lol

Jon

user92578

1:49 PM

I remember reading from a devlog or something about designers coming to programmers "in this level nothing really works, but it works fine on other levels"

user92578

There was some leftover code like that from a previous project

Jon

So this particular level, the teeter here does not settle

So I have to write a special case in to say, don't check for those two to settle

MickLH

lol

Jon

I should write in a property

But at this point i'm like frig this shit

MickLH

Now you're all designing and shit

Properties... pfffft where da hacks at?

Jon

1:50 PM

i really don't see the point of writing a property now...

but I imagine I will be like.. shit shoulda wrote a property

MickLH

Properties actually does seem like a good way to deal with that

user92578

man that is exactly what I believe releasing something is like

MickLH

Like if it came up again

Jon

There is one more level

where there are ropes supporting the final objets

I still want to check if they are resting so it is a little different

I need to check if they are resting at a higher threshold than I would in other levels.

So that property should be a float

sn0k3

Jon, from where I can try your game?

How to paint a square where is the mouse cursor's position?

user92578

1:54 PM

In what framework?

MickLH

@sn0k3 PaintSquare(Mouse.Position);

sn0k3

Hm, no

wait

MickLH

lol

NaCl

@MickLH That is possibly one of the most ugly codewise user interfaces I ever saw

sn0k3

I am not talking about that

MickLH

1:55 PM

I went with his words verbatim :P

Jon

@sn0k3 trying to get the build finished now

sn0k3

aha

How to convert mouse position in tile size

wait, I will send you a picture

MickLH

Mouse.Position / Tile.Size

sn0k3

but paint can't snap cursor

I tryed that

It isn't working

MickLH

There is no point in arguing that "Math doesn't work."

sn0k3

1:57 PM

after moving the mouse it just paints +1

wait a second

MickLH

You should refine your problem to what you actually are trying to achieve, that's what I'm actually saying behind my messages

I wouldn't just give you ridiculous code and say "seriously use this"

sn0k3

drive.google.com/open?id=0Bzh1ESW_-CAoaTFlVk5YQXpUUWs

the red thing is the cursor position

I am trying to make the tile ( which is the rectangle with width 25 and height 25 )

centered of the cursor's position

MickLH

Your question is still ambiguous, and the two trains of thought I pointed you at cover both possible cases you could mean.

There's nothing more that can be done until you become sure what you actually want. This is not as trivial as it sounds because if you were sure 100% what you wanted you would be typing the code.

sn0k3

I am trying to center the tile to the cursor position..Something like the tile is outside and the cursor is inside the image (tile image)

public void mouseMoved(MouseEvent e) {
int mousePositionX = e.getX();
int mousePositionY = e.getY();

paintRectangle(mousePositionX / 25, mousePositionY / 25, 25);
}

this is my mousemoved function

25 is the size of the tile

MickLH

Ok does paintRectangle take X and Y in pixels, or by tile ID?

user92578

2:03 PM

You need to round, and then multiply

MickLH

because it takes the size in pixels, and ignore Tyy

sn0k3

ooooooooooooh!

MickLH

Ignore him.

He's wrong.

You need to floor not round. You are already flooring.

Integer divide floors.

user92578

rectX = floor(mouseX / 25) * 25

MickLH

You probably need to multiply, which is why I ask if you need pixels or tile ID

user92578

2:04 PM

(or floor, actually)

MickLH

@Tyyppi_77 This is straight up wrong. Use floor

@Tyyppi_77 You are wasting everyone's time butting in stepping on my toes with wrong advice and slowly correcting it to advice I gave a minute or two ago.

sn0k3

Well, what do you mean by tile ID?

pixels I guess..

MickLH

Tile (0, 0) is at (0, 0) but tile (1, 1) is at (25, 25)

sn0k3

yea

MickLH

So you use Position / Tile.Size to get the tile ID

sn0k3

2:05 PM

I am rendering the grid like that:
for(int y = 0; y < screenY; y++) {
for(int x = 0; x < screenX; x++) {
g.drawRect(x * TILE_SIZE, y * TILE_SIZE, TILE_SIZE, TILE_SIZE);
}
}

Aha

MickLH

paintRectangle is the only function that's possibly relevant

sn0k3

Well

I should paint the grid on other way

MickLH

Anyways stop getting ahead of yourself

Do you understand why you use floor division and throw away the remainder?

Almo

@sn0k3 hit "fixed font" when you enter code

MickLH

Do you understand why you need to multiply the tile ID by the tile size?

I need to smoke a joint so I can human. brb

sn0k3

2:08 PM

What do you mean by this "Anyways stop getting ahead of yourself"

MickLH

I mean focus on one point and solve it, do not think randomly about other topics until you finish the task. That is just a form of procrastinating.

Specifically it's a way for you to procrastinate that also wastes my time. I won't put up with it.

Leggy7

don't be so harsh @MickLH, lol

sn0k3

well

MickLH

4 mins ago, by MickLH

I need to smoke a joint so I can human. brb

you didn't give me enough time to roll

user92578

did you get it to work sn0k3?

sn0k3

2:12 PM

no

MickLH

jesus

sn0k3

because I dont store tile id

NaCl

@MickLH I don't like joints

sn0k3

Isn't that illegal?

user92578

@sn0k3 you can calculate those in the way I showed you

Leggy7

2:13 PM

yeah but mick is a rebel

sn0k3

:D

NaCl

UUUH, maybe

MickLH

public void mouseMoved(MouseEvent e) {
    int mouseTileX = e.getX() / TILE_SIZE;
    int mouseTileY = e.getY() / TILE_SIZE;

    paintRectangle(mouseTileX * TILE_SIZE, mouseTileY * TILE_SIZE, TILE_SIZE);
}

(avoid magic numbers)

sn0k3

drive.google.com/open?id=0Bzh1ESW_-CAoV1Q3SzF4elluVlE

HEHE It worked!

Leggy7

cheers!

user92578

2:15 PM

nice!

Blue Bug

noice!

MickLH

@sn0k3 Seriously please understand why that works though, please.

sn0k3

I didn't saw your code fully @MickLH , I just saw your first 2 lines and decided to multiply by 25 in paint function

Thank you guys

Well

MickLH

As long as you understand why it works, you'll answer so many of your own questions

Leggy7

about to release, @sn0k3?

MickLH

2:16 PM

And see entire new spaces of ideas to work with

sn0k3

int mousePositionX = e.getX() / 25;
int mousePositionY = e.getY() / 25;
this gets the tile id ( tile 1 is at (0, 0) tile 1 is at (1, 0) ... )

but I'm not sure why to mult by the tile size?

MickLH

Lets call it "Index"

user92578

because you need to convert to screen space

sn0k3

@MickLH Which one?

MickLH

The number that goes 1:1 with each tile, it's a tile index

It's also an identifier, but there are many other identifiers that are equally important to the word "identifier" but index is a bit more specific

sn0k3

2:19 PM

okay

after getting the tile index I should multiply by tile size in order to convert it into screen space - is that it is?

MickLH

That's a valid way to interpret what's going on

user92578

yeah, so that the next tile always starts after one tile size has passed

MickLH

Thinking in "spaces" can be more complicated, but is a good technique because it covers almost all conversions in game development

To think of it in spaces, you have a number line that goes 1, 2, 3, for each tile, aka "Tile Index Space" and you have a number line that does 1,2,3 for each pixel, aka "Screen Space"

sn0k3

aha

MickLH

If each tile is 25 pixels large, then to convert from tile space to screen space, you'll turn 1 into 25, and 2 into 50

So Screen Space = 25 * Tile Space

sn0k3

2:23 PM

yes

shouldn't be screenspace = tile_size * tile_index

MickLH

Yes

sn0k3

aha

okay

thank you

MickLH

np! I always appreciate someone not getting mad at me for being low on patience :P

sn0k3

@Leggy7 to release what?

Hm, interesting..

It paints the bottom tile, instead of the tile, where is the cursor position

tile0 = (0, 0)
tile1 = (1, 0)
it paints tile1, but mouse is on tile0

user92578

code?

sn0k3

2:32 PM

I fixed it

:)

ty

mousePositionY * 25 - 25

user92578

that's not a sustainable fix

user92578

that's a patch

MickLH

hack*

sn0k3

you mean, because it is hardcoded?

MickLH

A patch is how you distribute a sustainable fix...

user92578

2:33 PM

you really don't want to do that, you want to figure out why you get wrong Y values in the first place

MickLH

@sn0k3 What corner is (0, 0) in?

sn0k3

top left

but I will check again, wait a second

MickLH

And do you count starting from 1, or from 0?

sn0k3

it is top left

from 0

If you mean in the rendering the grid part - yes

MickLH

@NaCl Whats wrong with joints? seems fine to me! they are pretty efficient

NaCl

2:44 PM

They are the opposite of efficient

Thy burn most of the stuff you want away

But besides that, they just taste really bad for me

fun to build them tho

MickLH

I'll find some papers if you don't believe me, it was a shock to me but experiments seem to agree that joints deliver the most crap and the most thc overall. Specifically such that the ratio of thc to crap is relatively higher than a bong because the water is actually more effective at filtering thc than at filtering ash

sn0k3

why do you smoke them?

for fun or?

NaCl

@MickLH except for vaporizers

MickLH

well nothing can compete with a proper vape setup lol

maybe edibles in some cases, but idk it's just different :P

NaCl

Agreed.

MickLH

2:56 PM

canorml.org/healthfacts/smokestudy.html

lol I think this is the most recent published thing I've seen

They basically end up saying (joint > bong && dabbing wrong != dabbing right)

Jon

3:12 PM

ok well i have my test build ready... still some stuff i want to do, but its ready --- can't build though my son is on my deploy pc playing games

NaCl

they blink a lot

Jon

that is what I was thinking lol

user92578

yeah otherwise awesome

Jon

gonna lower the blinkrate

NaCl

It's smewhat hypnotizing

Also, what's up with the blue one up right? Doesn't blink at all

Jon

3:24 PM

blink is totally random

NaCl

Okay, makes sense

just not captured in the gif

user92578

you should put in one retarded one that just doesn't blink

NaCl

lol

Jon

it would be cool if I did try to evolve the characters even further

There is this interesting shape shifting mechanic that could be cool to do

NaCl

pls no transformers

Jon

3:26 PM

A Yellow(or whatever unused color) block that changes between a circle and a square

NaCl

That's cool! On click?

Jon

That is the issue

It completely changes the core mechanics really

previously all you can do is touch stuff

and it dissapears

NaCl

hmmyeah, they used to disappear if you click

user92578

don't let yourself be the victim of the feature creep

MickLH

can you rotate 45 degrees and switch and use it to pop up to somewhere higher in the map?

user92578

3:27 PM

NaCl

What about if you click it, it changes shape, if you click again it disappears

user92578

A long refactor later I'm back to where I started from

Jon

That would be pretty cool

MickLH

lol jon be careful

Jon

gorb2

@Tyyppi_77 love those circles at the end

user92578

3:28 PM

me too, it's a little thing but just makes it look more polished

MickLH

@Jon bro do u even dlc tho?

user4704

The blur and shell casings are nice touch too.

user4704

Do you have shell casing clatter sounds lined up?

user92578

No actually

sn0k3

Any ideas why when I resize window the rectangles, which have being painted with mouse disappear?

somewhere is called repaint()

but interesting thing is that these in main paint method does not dissapear

user4704

3:31 PM

When I look at the gif full sized there is an occasional flicker of green near the characters ear

user4704

is that a compression artifact?

user92578

Yeah it is, that happens actually in almost every of my gifs

Blue Bug

3:51 PM

apple.eat(a) banana.eat(a,b) Cherry.eat(a,b,c), all inheriting from class Fruit and Fruit has eat(), what is the correct way to achieve this? same function name with different number of arguments. Do I just hide Fruit's functions? and call it from inherited class?

Jon

if you spin a square really fast in unity, does it become a circle?

MickLH

@Jon maybe a circle with an inner radius, and an existence probabilistic gradient out to the outer radius :P

It's not really random though, but if it's faster than the framerate you'll get the nyquist effect which could appear random sometimes
