Carbon is a lot better when it's missing two electrons. (C++)

user92578

07:36

OOOOkay

user92578

Now back to the level file IO

user92578

It's gonna be quite messy

user92578

I need to separate the actual level loading and the loading to the level editor, because their needs are just so different

user92578

Maybe I can clean it up once I'm done

user92578

Basically the level editor doesn't load triggers or collision meshes, only the tiles and the entities, and it generates the collision data and the triggers based on the tiles and entities

user92578

07:38

But the level needs triggers and collisions, so I need to write them to the file

user92578

See how messy this already is?

user92578

</rant>

user92578

sorry

Hjorthenify

Just got a brand new monitor for my birthday, but it turns out that windows 10 has ruined my HDMI port -.-

@Tyyppi_77 Not too bad. Just add optional metadata :P

user92578

@Hjorthenify nice and not nice

user92578

07:49

it's your birthday?

Hjorthenify

Yup

user92578

grats a lot!

Hjorthenify

Thanks :)

At least I can use the monitor for my pi

user92578

Ah

Chris

happpy bdayyy

RIP HDMI port

Win10 just not liking it?

Hjorthenify

07:58

I think it has something to do with the way windows 10 handles dualgraphics

and thanks :)

Just tried to disable my intel card. That just made win10 go nuts

Chris

:(((

Hjorthenify

08:15

I really need to get my dual boot setup..

Kevin van der Velden

Happy birthday @Hjorthenify!

user92578

08:40

How old are you now Hjor?

user92578

08:55

user92578

It's something I guess

user92578

Ah,I think I was writing in the wrong order

user92578

Okay, now I've got tile saving & loading working!

user92578

Now I need to clean up, and then add trigger & collision saving

Hjorthenify

09:18

@KevinvanderVelden Thanks!

@Tyyppi_77 20

user92578

That's a nice and round number!

user92578

Feel old yet? :D

Hjorthenify

nope

user92578

09:38

WinAPI file dialogs totally freeze when I try to use them

Kevin van der Velden

Do you keep doing the windows event loop?

user92578

I don't think I need to do that

Kevin van der Velden

Then you would think wrong :)

user92578

Well

user92578

It's working fine now

user92578

09:41

I just didn't make the dialog a child of my game window

Kevin van der Velden

Ah

That would also help

user92578

I don't do any events stuff, and now it works smooth

Kevin van der Velden

Are you still rendering the game or are you busy blocking till you get a response?

user92578

I'm not sure how that works

user92578

I'd think that the game freezes

Kevin van der Velden

09:42

Check it out, do things still render? =p

user92578

Now if froze again

user92578

It's not a child of the game window

user92578

Game window is unresponsive

user92578

The file dialog is just all white

Chris

I don't think I've seen a game use the OS file dialog box before

Aidan Mueller

09:45

I have back in the day.

Chris

they just get the directory structure but render it in-game, rather than using anything native

yeah for sure, but these days...

Aidan Mueller

I think I have anyway.

I was probably like 4 though.

user92578

I think that doing my own file dialog would be way out of the current scope at least

Chris

Windows 3.1 maybe

Aidan Mueller

No. LOL.

I'm not that old.

I'm 16.

user92578

09:46

Sure, it would be cross-platform, but for simple dev tools...

user92578

What? You sound so smart that I've thought you're a lot older

Chris

I'm thinking Castle of the Winds had a save/load feature with that

user92578

Or maybe it's just the fact that you use your full name

Aidan Mueller

Well I didn't intend to use my full name, I just never bothered changing it.

@Tyyppi_77 Sounding smart isn't that hard these days :D/:(

user92578

:D

Kevin van der Velden

09:50

Sweet, pathfinding is done! :D

user92578

Nice

Kevin van der Velden

I'm at 11101 bytes

Hjorthenify

@KevinvanderVelden What method?

Kevin van der Velden

A*

user92578

Any ides why my dialog might freeze?

Hjorthenify

09:51

Ah

@Tyyppi_77 SDL doesn't handle some events correct?

Kevin van der Velden

No short circuiting (i.e., it searches the entire map instead of stopping when it has a proper target), no diagonals (they would look weird in the isometric map anyway) and it uses the javascript build in sort

user92578

Here's what happens:

user92578

Kevin van der Velden

Because that is way easier :D

user92578

I don't think it's an SDL event thing

user92578

09:56

fuuuuck

user92578

I just want to get this done quickly because I have loads and loads of homework to do

Kevin van der Velden

You could try plugging this thing in: github.com/mlabbe/nativefiledialog

user92578

I actually thought about that

user92578

However I am more of a "do it myself" type of guy...

user92578

Also looking at the source that seems to do it exactly like I'm currently doing

Hjorthenify

10:12

@KevinvanderVelden How are u with C#?

Ali.S

@Tyyppi_77 that's so different with the layout I use

user92578

10:30

user92578

That's my usual layout

user92578

Then I have to filled layout for debugging

Ali.S

usually keep solution explorer in the left, and output window is usually open

user92578

Now I'll do a lot of homework

user92578

Ah

user92578

10:31

I keep the solution explorer on the right because then it's on the edge of my monitor, as I keep VS on my right monitor

user92578

It wouldn't make sense to keep the solution explorer in the center or my focus

user92578

I'll be back once I'm done with the homework

Ali.S

10:47

@Tyyppi_77 I never thought of it that way... but then again, I usually have VS in my left monitor, so I guess it's the same logic as your :P

Kevin van der Velden

@Hjorthenify it's my day job

=p

Hjorthenify

Ah cool :D

Pip

11:17

morning all

Kevin van der Velden

\o

Pip

@Hjorthenify Happy Birthday!

user92578

11:40

Well I was really productive!

user92578

Wrote my part of the physics project and finished my religion summary for this week

user92578

Hey @Pip, how's it going?

Pip

still have some homework to do before school starts

otherwise, good!

user92578

Now on to the dialog fighting

user92578

Fuck

user92578

11:51

Sometimes it works, sometimes it doesn't

user92578

Ha!

user92578

I had to disable Visual Leak Detector

user92578

12:09

So yeah, I can now edit and test (almost) functional levels

user92578

Pip

awesome

Moses Aprico

12:24

Hi guys

user92578

Hi

Moses Aprico

Sup? Newcomer here

user92578

Welcome!

user92578

I'm working on a level editor for my game

Pip

Tyyppi is doing work

Moses Aprico

12:25

what game engine are u using?

Pip

He's not

user92578

I use SDL2 for everything, but the whole framework is my own

Pip

All of his graphics are straight SDL

user92578

C++

Pip

welp. Sniped :P

user92578

12:26

Haha :D

Moses Aprico

wow

hardcore there i reckon

user92578

Not really

user92578

I just like being in control of everything

user92578

Well, of most of stuff

Moses Aprico

go for obama's replacement in next election then

jk

:D

user92578

12:27

lol

Moses Aprico

have you ever use unity?

Pip

I have

@Jon uses it frequently

Moses Aprico

i'm new to unity, so i'm not sure what's this kind of functionality called

basically

i wanna make a game, which skin can be purchased via iap (like crossy road char change)

so, players can change his/her char in-game

how to learn about that?

i mean

Pip

I mean

Moses Aprico

the keyword to google

Pip

12:30

that's not super hard.. there's no real key word

Moses Aprico

not sure how to phrase such functionality

Pip

you literally just assign a different sprite to it

Moses Aprico

so you are not making a new prefab to every single character right?

Pip

nope

Moses Aprico

i see

Pip

12:31

one prefab, keep track of the sprite in an encrypted text file or something

assign the correct one on game load

Moses Aprico

so, if I'm correct, the character prefab is just an empty object with a script attached to manage which sprite is shown. right?

Pip

It needs a sprite renderer

and any other components that you want

but yes

Moses Aprico

oh sure. forgot to mention sprite renderer

1 more thing i'm not quite sure

Pip

sup?

Moses Aprico

what's the best method to keep screen:character same?

Pip

12:35

screen:character same?

Moses Aprico

so, on larger device (tablet or such), the object will be larger

Pip

oh i see

user92578

The aspect resolution

Pip

you want the resolution the same

Moses Aprico

yeah

hmm

Pip

12:36

(aspect ratio, sorry)

Moses Aprico

i mean

Pip

answers.unity3d.com/questions/23291/…

Moses Aprico

i want to make a character is 1/8 of the screen width

Pip

both answers are solutions

Moses Aprico

so i'm not going to "assign" the value directly

ok i'll check it out

Pip

12:37

coolcool

Moses Aprico

english is not my main language, so looking the "keyword" to google for certain problem is common

haha

Pip

heh, not an issue

A lot of the people speak other languages in here. We all chat in English, but... yeah

user92578

Small thing, but I added file type filters to the dialogs:

user92578

Pip

Make it "Level File (.lvl)"

user92578

12:40

Ah right, sure, thanks

Pip

np

user92578

Uuuh I would so like to wrap rapidxml in my own XML layer...

user92578

hmm

user92578

Maybe another day

Pip

what's rapidxml?

oh nvm

user92578

12:45

It's the library I use for reading & writing XML data

user92578

@Pip dude I so thought that there was a piece of dust on my monitor on the second line of that

Pip

lol sorry

Unintentional :P

user92578

:D

user92578

13:08

Hmm

user92578

Something is fucked up

user92578

3c4c 6576 656c 2000 3d22 3230 2220 003d

user92578

Stuff like that ends up to the level file, no human-readable data

user92578

It's valid text data

user92578

But it looks like that

user92578

13:11

I dumped it into a hex editor and it turns out to be valid XML

user92578

Something is wrong

user92578

No idea what

Jon

wizard put a hex on it

user92578

heh

Jon

you are not saving it as hex data?

user92578

13:14

No

user92578

And it just worked, I just added a convenience method for adding attributes

user92578

Got it

user92578

Super weird behaviour

user92578

So it was a string lifetime issue

user92578

Which for some definitely sane reason ended up with the document writing it's data as hex

Moses Aprico

13:32

@Pip hi pip. is unity doesn't detect field of view when changed via script?

private float myDesiredHorizontalFov = 9f;
private float defaultAspectRatio = 9 / 16f;
private Camera myCam;

void Start () {

myCam = GetComponent<Camera> ();

Debug.Log (myCam.fieldOfView);
myCam.fieldOfView = myDesiredHorizontalFov *defaultAspectRatio / ((float)myCam.pixelWidth / myCam.pixelHeight);
Debug.Log (myCam.fieldOfView);
}

the "Game" view seems doesn't changed

user92578

Does the code run?

user92578

What does Debug.Log show?

Moses Aprico

testing on 9:16 and 10:16 respectively

another thing which is weird is, the 9:16 should equal, since it's the same as my defaultAspectRatio

but it's not

user92578

forum.unity3d.com/threads/scripting-field-of-view.599

user92578

Tells you to use the "Main" camera

Moses Aprico

13:53

yes, it's my main cam

user92578

and is the camera orthographic?

Moses Aprico

user92578

Yeah field of view doesn't apply to orthographic camera

Moses Aprico

not sure on what orthographic means. (it's a 2d game so..)

user92578

orthographic camera ignores perspective

user92578

13:54

All tough you'd want to confim this from an Unity guy

Moses Aprico

perspective camera somehow scrambled up the view

not sure why

user92578

docs.unity3d.com/ScriptReference/Camera-fieldOfView.html

user92578

> Field of view is ignored when camera is orthographic (see orthographic)

Moses Aprico

yeah. i never tweaked that prop before. thanks for reminding me

perpective cam! scrambled up the view lol

so

i have another idea on this

user92578

for a 2d game you probably want to use the ortho camera

Moses Aprico

13:57

yeah

i think i'll tweak it a bit first

thanks

Hjorthenify

@MosesAprico Use Size, not FOV for ortho also use Camera.main to access the camera instead of getting the component(unless you plan to have multiple cameras)

Size (when Orthographic is selected) The viewport size of the Camera when set to Orthographic.
Field of view (when Perspective is selected) Width of the Camera’s view angle, measured in degrees along the local Y axis.

From the documentation

@Pip Thanks!

Pip

HOLY CRAP Hjor

Moses Aprico

@Hjorthenify hi there. thanks for replying! actually i'm going to check out the size too now (inspiration after going to toilet lol). :)

Pip

that startled the crap out of me XD

np :D

Hjorthenify

@Pip You're welcome! :D

I can't decide how I want to structure this pathfinding system -.-

Hjorthenify

14:23

It takes less than 80ms to generate this clusterfuck

Pip

looks like you need some culling, still

but nice

Hjorthenify

Yeah I need to remove nodes which are close to each other

Pip

no kidding

Hjorthenify

Well merge them :P

Ali.S

@Hjorthenify how did the original mesh look like?

Hjorthenify

14:24

And remove lines which are close to each other and going the same direction

user92578

Nice job

Hjorthenify

Ali.S

may I ask, what you were trying to do, that ended up in that mess?

Pip

It's a pathfinding visualization

Hjorthenify

@Ali.S Polygrid map

I'm refactoring my pathfinder, but otherwise I would have shown you :P

Ali.S

14:27

still I don't get it... but I guess it's not as bad as it seems ...

Hjorthenify

There is room for optimization, but the pathfinder itself is quite fast

Almo

if you learn one thing from TIS-100, it's that there's always room for more optimization

Hjorthenify

Haha true :P

Almo

:)

if you play that game add me on steam so i can see your scores

Hjorthenify

I will once I can afford it :D

Almo

14:36

:)

Hjorthenify

Also the code is available on bitbucket(it ain't pretty) if anyone is interested: bitbucket.org/Hjorthenify/pathfinding

Hjorthenify

14:50

Also if you take a look at it and have any suggestions, feel free to use the issue tracker or ping me here :D

Jon

holy crap

that is a lot of lines

i haven't seen that many lines since a rick james concert

Hjorthenify

@Jon I haven't seen that many lines since I saw a Trentemöller concert

user92578

Okay I think I'm ready to start adding entities

user92578

Maybe

user92578

I'll try and see what happens :D

Hjorthenify

14:59

@Tyyppi_77 What kind of entities?
