I'm so tired of my credit card being stolen.

Chris McFarland

yikes
dodgy sites?

PearsonArtPhoto

No idea. One way or another I have my card stolen at least once a year...

Chris McFarland

:(

PearsonArtPhoto

Target and Home Depot were definitely two of the culprits.

No idea this time.

In any case, I was just trying to transition off of that card to make it my backup card, so...

Sie

3:48 AM

Do you not live in that good of an area? Home Depot and Target are usually on the up and up where I live. Hell people go to Target to avoid Walmart lol.

Not 100% with the door, thoughts?

user92578

8:07 AM

there's an adjective missing there

user92578

100% happy*

Darth_Wardy

@Tyyppi_77 it looks like the door is made of stone

maybe give it a metalic look or something

make it out of iron or steel

user92578

The prison doors are metallic

user92578

So I wanted to do something different for the bunkers

Darth_Wardy

hmmm ... so is this like a blast door ?

user92578

8:11 AM

Yeah I was going for a heavy look

user92578

Maybe it should be thicker?

Darth_Wardy

hmmm, that's an idea

or because its such a heavy door have open and close a bit slower

but that might promote some annoyance during place

user92578

yeah I feel like it can't really be slower TBH

user92578

It's a little better already I think

user92578

8:19 AM

The window is a little awkward too I guess

user92578

Uuh

user92578

I just noticed how my flipping cheat flips the shading on the side stones

user92578

8:33 AM

user92578

I think this is a lot better

Darth_Wardy

8:58 AM

as its like "bunker door" would it not be cool to make it the width of the wall ?

hmm that might be confusing to users though

forget that idea

Jon

9:32 AM

nice

Why there are no fast and GPU drug free 2D engines/libs nowadays?

Darth_Wardy

9:59 AM

drug free? ... lol ... why does 2D require a gpu? it's a parallel problem in places but usually not massively parallel

or did i miss something

Jon

Q: 2D library/engines that runs fast on any modern PC

ToME, FTL and a lot of other 2D games that move just a few sprites and pixels per frame on the screen are getting 2-10 FPS on modern 3.1 GHz CPU with 8 Gb of memory. How come that the game industry pushed so hard for GPUs that now it is impossible to run a game that would be lightning fast on 166...

Darth_Wardy

quality question lol

I felt it should a have deservingly bad 2D answer that clearly misses the point

Jon

totally commented on it

ugh... this egg sandwich sucks.

UGH

Alexandre Vaillancourt

10:46 AM

@Darth_Wardy Someone thought it was low quality.

NaCl

@Jon Eggs suck in general :P

Jon

In general?

I don't think I have ever witnessed an egg sucking

DH.

Eggs are good, I prefer them boiled

Jon

I eat them boiled all the time

I like to dip chicken into egg yolk

Its like a sacrificial bath

NaCl

I don't really enjoy chicken period

Alexandre Vaillancourt

11:00 AM

lol

Jon

chicken period sounds pretty nasty

NaCl

That's why it's called egg

Jon

try saying that 5 times fast in front of black people

DH.

lol

NaCl

11:16 AM

ez as $\pi$

Darth_Wardy

@AlexandreVaillancourt I think you missed the sarcasm there, like in the comment trail on my answer

Alexandre Vaillancourt

I did not miss it: someone else flagged it as low quality, which was clearly not the case, and I hit the 'looks okay' button. It was effectively a bad answer to a bad question :)

Darth_Wardy

that was the point

2d engine cpu

Alexandre Vaillancourt

Yeah :)

Darth_Wardy

I can't seem to get any hits when I google "bla-bla-bla memory" though

Alexandre Vaillancourt

11:25 AM

It's just that some ppl out there like to use flags instead of the downvote button.

We'll have to remind our artists that a LOD is not only about poly count, but also about texture count...

user92578

I'm so cheap that I don't like to downvote

user92578

I try to not flag questions that shouldn't be flagged though

Alexandre Vaillancourt

Yeah, I aimed some thresholds in my rep to get the privileges that come with it, but at some point, well it's just rep, losing one point here and there doesn't hurt.

And often I see a +1 popping on my reputation count, because a -1 answer got deleted or something :P

user92578

Yeah like I'm trying to get to 1K currently

user92578

I answered a question yesterday like 14mins after it was posted but the OP still hasn't responded :(

user92578

11:30 AM

I can only really answer SDL questions so I try to snatch all those

Alexandre Vaillancourt

Yeah, way to go :)

user92578

So I'd like to try putting together a small test trailer, is Windows Movie Maker in any way competent for that stuff?

Alexandre Vaillancourt

Sometimes I get lucky and answer a question that gets promoted across the network. Get tons of rep like that.

user92578

I need to make a trailer eventually so I'd like to practice a little.

user92578

My answers are rarely cool like that, often it's just a link to SDL docs and an explanation

Alexandre Vaillancourt

11:32 AM

I have no idea; here we capture with Bandicam, but I don't have a clue about what tool they use to produce the final video.

A: Rotating hitboxes in pygame?

As mentioned, pygame doesn't directly offer support for rotating hitboxes. However, you could either look into coding your own non-axis aligned box classes, or use a little cheat. The cheat basically calculates the axis-aligned hitbox that completely contains your sprite. It's pretty easy to calc...

user92578

That's probably my "coolest" answer

Alexandre Vaillancourt

Yeah, those questions are really more generic (and often off topic, but I don't answer those).

user92578

@AlexandreVaillancourt Yeah I tried a bunch of free ones a week ago but they all seemed to struggle with... well, responding to Windows

user92578

Crashed like 3 different programs with a single clip

Alexandre Vaillancourt

11:33 AM

Yeah, you got my +1 on that one hehe ;)

Hmm, what size are you using?

user92578

1920x1080 at 60 fps

Alexandre Vaillancourt

We've tried to capture 3 monitors wide, but the result is, well, shit. It only records the top fourth of the screen or so...

user92578

I've used VideoPad at school but the school has a license for it

user92578

Where is the Blender of video editors?

user92578

The GIMP of video editors?

Alexandre Vaillancourt

11:35 AM

Did you try to reduce the framerate?

Or you could try to do your capture at your school :P

user92578

Nope, but I don't think that really should be an issue

user92578

Capturing is not an issue, editing is

Alexandre Vaillancourt

Ah, right!

user92578

I use OBS for capturing and that works great

Alexandre Vaillancourt

I'll try that one!

user92578

11:37 AM

Now I'd just need an editor that allows me to apply transitions and most importantly crop the video

user92578

OBS is not 100% accurate on colors atleast according to the Cogmind dev

user92578

But it was really easy to setup and to me the quality is good enough

Alexandre Vaillancourt

You could try Adobe Premiere and pay for it for just a month (20$ USD)

There is apparently a free trial period as well!

Pichi Wuana

Hi. I'm new here!

PearsonArtPhoto

A very basic introduction to Unity Shaders. completeunitydeveloper.com/blog/introduction-to-unity-shaders

Leggy7

hi

user92578

@PichiWuana Hi! Welcome then!

Pichi Wuana

@Tyyppi_77 Thanks!

user92578

@PearsonArtPhoto Nice!

DH.

12:34 PM

I would like to take a look, but this site is being blocked by the company proxy

PearsonArtPhoto

Sadly that seems to happen... It's pretty basic, so...

Leggy7

@PearsonArtPhoto sounds nice! If you go in depth to basic explainations with the next one, my days to come will be made :)

Alexandre Vaillancourt

@PichiWuana Hello!

Pichi Wuana

What's new?

PearsonArtPhoto

I'm hoping to do a bit. I only understand a few basics, but I think I've got enough to do a 4 part series.

Pichi Wuana

12:40 PM

Is LibGDX with Android Studio a good place to begin as a beginner in game development? (I haven't almost worked with graphics, just with console...)

Leggy7

basics are what stops me from trying to write my own shaders

I can't really sort out conjunctions between sprites and shaders code

I do partially understand vertex and frag stuff (more vertex than frag)

but actually I lack time to practice it

user92578

@PichiWuana Java is a pretty popular choice, however not really my piece of cake

Pichi Wuana

@Leggy7 Where did you begin with Game Development?

Leggy7

@PichiWuana what do you mean? my first approach?

Pichi Wuana

@Tyyppi_77 I already studied 2 years of Java programming including Object-oriented. Is it enough?

@Leggy7 Yes

user92578

12:46 PM

Probably

Leggy7

big thoughts of my will to pursue a huge project like open world MMORPG with a lot of dynamic aspects

user92578

GameDev has it's own tricks and things, but you really only learn by doing

Leggy7

in other words, build an AAA title in 2 guys :)

user92578

I started with Pygame & Python, now I dev with C++ansd SDL2

Leggy7

btw I began with monogame xna

then I moved to Unity

Pichi Wuana

12:49 PM

I have taken tutorials on how to develop a complete game like a simple Flappy Bird with LibGDX (most just copying code but understanding) but I feel it's not the best approach because it is centered in some specific topics and then I don't learn the basics

Alexandre Vaillancourt

@PichiWuana You can make games with whatever you know. As long as it has a game loop, you can do a console game...

(console -> command line)

Pichi Wuana

@AlexandreVaillancourt Yes, I have done console game. What I want is to have graphics.

PearsonArtPhoto

Yeah, I'll see what I can do. The next part of my shader series is to go over in detail what the standard shader can do.

There's a lot more power there than I think most people realize.

Alexandre Vaillancourt

@PichiWuana Kk!

Pichi Wuana

That's my issue now

DH.

12:53 PM

@PichiWuana Android Studio can be a bit... frustrating even with those experienced with Java

To be really honest I started with Game Maker, which has a lot of stuff impossible to be done, but simplifies a lot of the low level stuff, so it's good to prototype or design basic algorithms

Pichi Wuana

@DH. Yes, it was a bit

Alexandre Vaillancourt

Well if you're comfortable with Java, I'd suggest you start with a Java engine. The one you mentioned is quite popular..

DH.

Now I moved to Unity as I had a course early this year, learning a lot still tho

Alexandre Vaillancourt

Maybe simply start with windows/mac dev at first before jumping to mobile..

Pichi Wuana

Unity is just 3D, right?

DH.

12:56 PM

Nope, both 3D and 2D

Pichi Wuana

@AlexandreVaillancourt Hmm, I think that's a good idea

But for Mac, if I'm not mistaken, I need Swift or Objective-C

PearsonArtPhoto

@DH. I think most game engines could state something similar.

LibGDX was what I was going to learn before I started learning Unity.

Pichi Wuana

Seems to be popular

Leggy7

unity is somehitng really really powerfull and quite easy to understand

PearsonArtPhoto

But very frustrating with bugs and some functionality that's missing that you'd think would be there...

Leggy7

1:00 PM

givs you a lot of features quite flexible to cover mostrly all the develpment concerns

Pichi Wuana

And it's with C# programming, right?

Alexandre Vaillancourt

@PichiWuana You can do Java on Mac

Pichi Wuana

@AlexandreVaillancourt Just which softwares? Just with LibGDX?

Alexandre Vaillancourt

Well the goal of Java is to be portable, so I guess you could work with Java and LibGDX on any platform.

Kevin van der Velden

Yes and no

Anything that uses the core java libraries is portable, libgdx uses platform dependent stuff for opengl rendering and such

Pichi Wuana

1:07 PM

oh ok

Kevin van der Velden

However those binary dependencies are available for multiple platforms so it does run on mac

It just doesn't run everywhere java runs

Pichi Wuana

I understand

Is Unity also used for modeling (e.g. Maya, 3DX Max, Cinema 4D, etc) or do people import their modelings?

Kevin van der Velden

It's not a modeling tool no

There's a texturing tool written in it (not as in a plugin for your game project but a standalone tool using the unity engine) which is pretty cool

Pichi Wuana

So people import their modelings?

DH.

Yup

user92578

1:57 PM

So I made a quick demo trailer, go check it out: youtube.com/watch?v=554YJKJ-XSw

Leggy7

great job tyyppi! but it lacks a very important feature: the epic voice telling the amizing things you can do!

user92578

Yeah all that stuff will be in the proper trailer eventually

user92578

That's was just me slamming gameplay footage of the different environments together with fades

user92578

I have a more proper trailer outline planned out for later use

user92578

And thanks!

Leggy7

2:10 PM

by the way it looks impressive. it is the first time I have a wide look of the whole screen. lot of action in your game tyyppi :)

user92578

I'm happy to hear that <3

user92578

Showing off your work is definitely one of the best parts of gamedev

Leggy7

actually the only thing that seems wierd to me is the ai

do you plan to make enemies respond faster? :)

user92578

Yeah I definitely want to improve the AI

user92578

the game is a little too easy

user92578

2:13 PM

but it's good that you reminded me of that

Leggy7

then just on thought

the screen is pretty wide related to your character size and allow you to know things that happens quite far from you. is this in the mood of the "keep it simple, keep it cool"?

because you could think to have the character not able to see what's not in his direct vision, like inside room with a closed door

but also maybe a thing like this breaks somehow the adrenalic setup of your game

PearsonArtPhoto

If the game is a little too easy for the creator, it's probably about right.

Or so I've always heard...

Leggy7

@PearsonArtPhoto i think that only an heavy beta testing would answer this problem

DH.

I don't think so

PearsonArtPhoto

Fair enough, but you probably don't want to make a game that's hard for you.

DH.

2:24 PM

If you game is supposed to be hard, you should just test it, you don't need to beat it yourself 100%

PearsonArtPhoto

Well, it depends on the game I suppose.

Leggy7

3:12 PM

I'm having an hard time to balance my game for instance. It is supposed to become very hard but should allow beginners to learn the basics. Then the learning curve should be quite fast but it is not easy to scale all the features

user92578

@Leggy7 yeah I've went for more of an "arcade" thing here

user92578

Q: How should we handle the 'inspector' tag and 'unity-*' tags?

The inspector tag mainly seems to exist to refer to the Unity inspector. There are fourteen questions with the tag as of this writing. As a tag, "inspector" alone is far too broad (not only Unity has a property inspector UI, for example, and it's generally unreasonable for one to be considered a...

can I able to change what is new text in android?

user92578

what?

Siddharth

I have published app into market but some what written wrong text in it

can I change it without publishing new build again?

Weapon X

@Siddharth Of course, at least in Google play

you need to click on uploaded build for this

then one dialog box come up and their you can update text

@Tyyppi_77 really thanks for help

@Wea

erebel55

Is burst fire in games actually a burst of ray traces or is a single ray trace with visuals to make you think it's a burst?

Siddharth

@WeaponX too :)

Weapon X

@Siddharth no problem i just hit the page and yes it is possible

user92578

@erebel55 Depends on the implementation I guess

DH.

@erebel55 If you mean burst fire from weapons in FPS games? Ofc, even because each shot is fired separately frame from frame, not to mention that it's pretty common to hit 2 of the 3 shots

erebel55

4:47 PM

yeah in FPS games

Almo

5:48 PM

@DH. usually (to my knowledge) a burst is a trace each shot, though as tyyppi says, you could fudge that and do a single trace and cheat. Though if your burst is over any noticable amount of time, players might notice

A trace every couple frames is ok. what networks DON'T like is lots of traces on one frame, so shotguns are frowned upon.

DH.

Except when you are on Serious Sam, because the shotgun in the game shoots in a pattern :P

Dominic Hughes

I just bought debra Anne Ross algebra books , pre-algebra + basic math , her geometry book , I also bought another book algebra a complete introduction and yea algebra is basically finding unknown numbers if you wanted a quick tip : ).

It's actually rather easy once you understand that concept .

Oh linear lol

Q: Where to start learning Linear Algebra?

I'm starting a very long quest to learn about math, so that I can program games. I'm mostly a corporate developer, and it's somewhat boring and non exciting. When I began my career, I chose it because I wanted to create games. I'm told that Linear Algebra is the best place to start. Where should...

Battlefield 1 Official Reveal Trailer

►

I'm going to die of hype in a few seconds

Luiserebii

hello

William Mariager

@TheMuffinCoder Remake?

Luiserebii

I have a quick question; what's the best spritesheet ripping program? I've been trying to use Alfred Spritesheet Unpacker, but it fails to make the sprites transparent. Any ideas? Or am I supposed to use a different tool to batch auto-transparent the images?

Jon

Trailer looks amazing

However it's EA

Gonna cost 250 to play

William Mariager

@Luiserebii Wouldn't that depend entirely on what system/game you're trying to rip from?

Jon

9:43 PM

The game play is. Gonna be. Dumbed down like battlefront

Luiserebii

@WilliamMariager Is that so? I've been trying to rip sprites from Undertale, off of this sheet: spriters-resource.com/resources/sheets/74/76988.png I assumed any program should get the job done...

William Mariager

@Luiserebii So you're trying to rip sprites from a spritesheet? :P

I didn't even know that was a thing. When I hear spritesheet ripping, I'm thinking ripping it from the game/system itself, like ripping all sprites from Mario or something. :D

In any case, the spritesheet you linked doesn't seem to have transparency.

Do you want it to do key-color transparency?

Luiserebii

@WilliamMariager Is that not the most efficient method? It seems difficult to directly read from an image for a game, I as I would have to keep track of all the pixel locations since they are of different sizes. Plus, I'm not sure how I would make the images transparent in Java...

And ahh, does transparency only work when the entire spritesheet has the same color? I was just looking at a guide, and it seemed to work with another sheet, but it was all green

TheMuffinCoder

@Jon I doubt it, this is meant for their current battlefield player base

William Mariager

Well, since the sprites a very simple, you could just pick something like Paint.NET/Gimp, use the magic selection tool, set tolerance to zero and then delete the parts you want transparent. I don't know any tool that'll do this automatically.

Luiserebii

9:51 PM

I think I'd be looking to make all the purple transparent; I assume the black simply can't be made transparent (because they are usually used in all-black scenes in game)

So this is just manual work I have to do?

William Mariager

That's what I'd do. It would only take a few minutes. :)

Luiserebii

ahh, ok, ill go do that, thanks!

Luiserebii

10:10 PM

Wow, surprisingly easier to do than I thought! Thanks again! :)

William Mariager

No problem :)

@Luiserebii, Just in case you don't know, there is also opengameart.org for your graphics needs. :)

Ripping is great for toying around, but with OGA you can actually upload and share what you're making.
