Game Development

Hi, does anyone know good tutorials on how to make a game feature that allows the player to create his/her own level and be able to export/import other user's levels?? any key words to use while searching? maybe game genre this feature excells at? any tips?

Chris McFarland

look up serialization and deserialization

say you have a map with various blocks at certain positions, various objects at certain positions

each object type could have an ID number - so you'd store the ID number of the object type along with its coordinates. serialize to a file that could be written or uploaded somewhere; receiving player then loads the file and interprets the bytes within and recreate the world

Q: Wrong contineous rotation to car

In my 2d game, I want to rotate car face based on collision detected. But at present after 3 to 4 collision its doing continuous rotation only rather than moving straight after collision. Here is my straight movement related code: myRigidbody.MovePosition (transform.position + transform.up * Ti...

please help me I am stuck

@Siddharth what have you done to debug?

user92578

A great start might be just printing the stuff to the console and seeing what value is the issue

MickLH

10:30 AM

@Tyyppi_77 I finally updated to SDL2

user92578

anything cool there for you?

user92578

isn't the windowing mostly same?

MickLH

@Tyyppi_77 SDL_ShowSimpleMessageBox

nice convenience

user92578

ah yeah that's awesome (I use it like once)

user92578

my store page was approved!

MickLH

10:38 AM

nice

and yeah it might only get used once but that spot really makes the user's life nicer when shit doesn't work lol

user92578

true

user92578

how was updating btw? I assume just a few lines changed?

MickLH

Well I have to get the OpenGL context manually now

Siddharth

11:17 AM

@Tyyppi_77 now I am available

basically cars moving based on AI

so cars moving itself and changing its direction when it collide with any environment object

jgallant

11:37 AM

you are on your own bro

type of issue like this is going to require some debugging

and if i'm doing that for you, i need to get paid :P

user92578

yeah, like I said, just output angles and stuff to the console and check which one isn't behaving correctly

jgallant

yeah.. i wrote a car sim, its messed up stuff

especially in unity -- the standard physics system they provide do not allow top down cars to be coded very easily.

Uri Popov

just download bullet physics

jgallant

no lol.

MickLH

I always end up bolting bullet physics on when I want to knock props over lol

jgallant

11:40 AM

if i am using unity it is going to be box2d

ah yeah bullet is 3d right?

MickLH

yeah

jgallant

so yeah we are not in the same dimension

Uri Popov

I'm trying to get a decent cloth simulation going without dropping 50 bucks for obi cloth atm

will post if Ig et decent results

jgallant

yeah

cloth is hard

one guy had posted a question on gdse .. how to make realistic looking paper

i was like. LOL

MickLH

I remember bullet soft body not being that bad last I used it

jgallant

11:43 AM

docs.unity3d.com/Manual/class-Cloth.html

You know unity does cloth right?>

MickLH

I'm getting so fed up with the other team's code... I'm about to throw it all away

jgallant

Like.... print and throw it out?

Chris McFarland

lol

Siddharth

let me try to do something on my way :)

MickLH

I don't understand why people think a disorganized pile of shit code counts as "finished" when another human has to continue adding onto it afterwards.

jgallant

11:46 AM

finished for him

MickLH

Not really because he's definitely not getting paid

He tried to save an hour or two and lost all of them.

The worst part is it's made up to look better than it is... and it still looks like shit

Like it pretends to have structure, but half the cleanly named variables aren't used at all

it's the variables like o and ad that actually matter

jgallant

We had a consultant at my work that wrote this engine

then i started digging into the code and found out it was ripped out of a Microsoft Foundation Library source code

He had taken the code line by line and removed all the comments

Said he wrote it

Chris McFarland

lol :(

jgallant

Tell me about it... what can you do

MickLH

I guess that's "writing" sortof like how making a frozen pizza is "cooking"

nah not even a frozen meal... a bowl of cereal

@jgallant You can leave a burning bag of dog shit on his door, knock, and run away.

which is what I'm considering at the moment

but they did admit it doesn't meet spec so I can't get that mad

Uri Popov

12:32 PM

ok bullet physics for unity is hard

@jgallant unity does cloth in a crappy way I think

then again I need to experiment with a high poly mesh

MickLH

1:42 PM

Fucking finallyyyy it is not convenient to star from my phone. That feels like an accomplishment, lol I had to break the rendering to get it large enough to click

user92578

what? are you not using the new mobile ui?

MickLH

Nah I have my mobile browser set to masquerade as a desktop browser

user92578

but why?

MickLH

because half the time the desktop site is a horrible pain, but the mobile site is outright missing the function I need

user92578

1:48 PM

all right

MickLH

I'll try their new mobile client lol

user92578

I haven't actually tried that in a while either

MickLH

Damnit they don't give me the new thingy lol

How do I opt in to the one in the screen cap there?

Stephane Hockenhull

So many sites mis-identify Linux browsers as mobile devices. But usually all it does is remove ads / splash screens so it's a win :D

Especially if you use an ARM-based desktop computer

user92578

hmm no idea, maybe in your profile page?

Stephane Hockenhull

1:53 PM

MickLH

I Feel a level of restless right now that I normally don't have to deal with

.I can't sleep knowing how much shit code I have to dump and rewrite

Stephane Hockenhull

ugh

MickLH

Bed 6am, out of bed 7am lol

No sleep in between

AHHHH I'm gonna explode im getting back on the fucking pc

jgallant

2:25 PM

Maybe you have mental issues

MickLH

Nah they got me on pills that's all fixed already

jgallant

That's a workaround

John Hamilton

@StephaneHockenhull I shouldn't star that right? Right.

MickLH

@jgallant You talkin shit bout my reality foo?

user92578

2:40 PM

user92578

How's that for a trading card?

War

Hey guys

MickLH

ayyyy wardy

War

@Tyyppi_77 still working on Gun Hero? How's it going these days?

user92578

release soon, just published my store page

War

2:42 PM

Hi mick

Nice

jgallant

Can you put the background on the card?

Too busy?

War

Hey @jgallant still improving gorb or did you go back to your voxel miner game?

user92578

Like this?

jgallant

Yeah

@War getting Gorb ready for steam

And putting 1200 newevels in picross Touch mobile

War

2:54 PM

Nice !!! Sounds like epic progress

jgallant

keeps my hobby going

Almo

3:36 PM

@jgallant woa... that's shitty

jgallant

3:50 PM

My son figured out that you can prevent blood moons by staying in climbing position

So now he is refusing to stop climbing

MickLH

got coalesced state snapshots working :) now joining mid-game works without hammering the bandwidth and without screwing up the synchronization

user92578

cool

Stephane Hockenhull

4:18 PM

@jgallant LMAO. It is a scary game event :D

My 7 y old covered his eyes the first time

There's no moon cycle indicator in BotW other than looking at the moon is there?

I'm waiting for the blood moon and it's raining so I can't tell if its tonight or I if can skip ahead by sitting

Well, 12:00 am came and no blood moon. guess I can skip

"Where is that bloody moon"
"TIMMY! DON'T SWEAR!"
"But moooooOOooom it's a bloody moon."
"Timmy! Last warning!"
...

5:40 PM

I just found my new favorite area in BotW to clear through, and a new favorite activity.

The Forgotten Temple

MickLH

6:14 PM

@Tyyppi_77 is there a way I can try to launch GunHero without steam's sketchy redistributable install bullshit

On my stock windows 7 machine it runs flawlessly and the only hitch is steam itself thinking it needs to reinstall the redistributable every time, but on my weirder setups the redist refuses to allow any progress

Which is frustrating, since I know you just wrote it in C++ on SDL, so your actual game will run on almost anything

If you have the option to disable the redist, I beg you lol. I will personally write you a redist checker / installer if you'll use it instead of steam's ridiculously literally amazingly fucking horrible one :P

I don't understand how such shitware is passed off as "professional"

I mean I fully understand that "professional" means fucking people out of their money while doing as little work as possible. That's how you get ahead in business. What I don't understand is why people pay to get shit on. Is the entire world masochistic cucks these days?

user92578

6:41 PM

@MickLH uuh I can turn it off but not right now, I've been meaning to write my own thingy anyways

MickLH

Do you know of a quick hack?

I kinda just want to play it lol

user92578

I'll try to use the steamworks site on mobile and turn off the checkbox, I hope the info isn't baked into the build

MickLH

oh man don't worry about it that much, don't go screwing with the steam settings over it

user92578

It's no biggie, everyone have it already if they need it

user92578

Aight I ticked off the checkbox, maybe try in a minute?

user92578

7:21 PM

And yes, Steams thingy fucking sucks

jgallant

Crashed your game again typ

user92578

cool, can you email me the minidump?

user92578

Or send it on discord, whatever

jgallant

When I get a chance yeah.

Your game crashes all the time man :P

user92578

I know, I suck

jgallant

7:43 PM

Oh well it's free

Been playing 2players

user92578

You mean coop? Yeah I haven't tested that at all

user92578

I should prob invite a friend over or something

jgallant

Step one, get a friend.

Step 2, invite them over so you can use them to test.

Step 3, ditch him when the game makes you rich

user92578

Most of my friends already have a key

user92578

I'm nice like that

user92578

7:59 PM

Maybe I'll try to lure in a girl with a promise of non linear balls

jgallant

8:16 PM

Girls love balls

Literally all they want is balls

MickLH

8:32 PM

@jgallant you forgot oscillation

Bálint

I come here, and one of the first things I see is Jon going about inappropariate stuff

Just as usual...

Stephane Hockenhull

@jgallant As father of a 2 year old girl, can confirm.

jgallant

8:49 PM

Errrr

Bálint

Let's just stop right here, before anyone misinterprets anything, k?

Stephane Hockenhull

jgallant

Is that your daughter?

Stephane Hockenhull

no, google imaged that

Bálint

@jgallant Yeah, he made a stock photo just for you in 2 minutes

jgallant

8:58 PM

Might have made it before

Parents are crazy

Bálint

Reverse image search?

jgallant

I'm on my phone

Just saw a pic of a girl surrounded by balls

Sorry

Bálint

Fair point

I made an image service!

Yay

monobogdan

Hi guys

Bálint

o/ Hi

Can one of you tell what you see?

jgallant

9:01 PM

White

With black border

monobogdan

I'm developing game for Android on Unity3D and i'm have bug with cars. Sometimes my car go... fly. Lolwut?

Bálint

That's awesome

jgallant

Did you try not making it fly?

monobogdan

I see image

Bálint

Give me a minute

monobogdan

9:02 PM

Any suggestions?

Except anti rollbars

jgallant

3d or 2d?

Stephane Hockenhull

Call your game "Car fly lolwut" and ship it

monobogdan

:D

3d

jgallant

Space taxi 3d

monobogdan

:D

jgallant

9:05 PM

So what's the deal, gravity too low?

Bálint

Strange, it doesn't onebox

monobogdan

vehicle mass if 2000

Bálint

Mass doesn't affect falling speed

Try going to the url "178.48.175.17:8000/<xyz>" after replacing <xyz> with a letter

jgallant

Mass affects falling speed

Bálint

Then refresh this page

jgallant

9:08 PM

F=ma

Bálint

@jgallant It doesn't, atleast irl

monobogdan

imgur.com/a/yZDVi

Lol

Looks like pseudo pbr?

It's unity 4.6 Free

Bálint

@jgallant You have to use the mass when you calculate the gravitational force

F = G * m1 * m2 / r^2 and a = F / m => a = G * m2 / r^2 where m2 is the mass of the other object, in this case the planet

Thus mass doesn't affect the acceleration

@monobogdan Does it just randomly fly away, or is there anything, that affects it

monobogdan

When i'm pressing left\right

i.e rotating wheels

Wheels are not 3d models, it's mask objects of real 3d wheels

I try record video

Bálint

A gif does it

You should download one of those screen to gif softwares, they're nice when you try to document problems

monobogdan

9:17 PM

1 ыус

1 sec

I can't record.

Rotating code:

FrontLeftWheel.transform.Rotate(Vector3.up, -1);
FrontRightWheel.transform.Rotate(Vector3.up, -1);

Acceleration code:

LeftWheel.GetComponent<WheelCollider> ().motorTorque = carSpeed;
RightWheel.GetComponent<WheelCollider> ().motorTorque = carSpeed;

Bálint

You have to refresh the site though

jgallant

9:40 PM

@monobogdan did you by any chance use existing code for this?

PearsonArtPhoto

I'm excited, I finally managed to kill a Lynel!

Bálint

10:00 PM

Anyone tried the game above?

monobogdan

Lol

I'm add antirollbars but car continue fly

WheelHit hit = new WheelHit ();
float travelL = 1.0f;
float travelR = 1.0f;

bool groundedL = LeftWheel.GetComponent<WheelCollider>().GetGroundHit(out hit);
if (groundedL) {
travelL = (-LeftWheel.transform.InverseTransformPoint (hit.point).y - LeftWheel.GetComponent<WheelCollider>().radius) / LeftWheel.GetComponent<WheelCollider>().suspensionDistance;
}

bool groundedR = RightWheel.GetComponent<WheelCollider>().GetGroundHit(out hit);
if (groundedR)
travelR = (-RightWheel.transform.InverseTransformPoint(hit.point).y - RightWheel.GetComponent<WheelCollider>().radius) / RightWheel.GetComponent…

MickLH

10:53 PM

@monobogdan are you of slavic origin?

monobogdan

?

MickLH

lol just read your profile. yep

monobogdan

Who or what "slavic origin"?

MickLH

@monobogdan I was asking if you're Russian or Ukrainian or similar

monobogdan
