@FreezePhoenix Maybe a "quick fix" would be to add "alt" text on the ui entities? Not sure how quick it would be, but that could give some indications until a more advanced UI is in.

The Mattbat999

@DukaZhou tried my game put yet?

Alexandre Vaillancourt

@TheMattbat999 Did you try to convert your c rpg to javascript (emscriptem)? (I have never done this, I only quickly looked at the topic.)

The Mattbat999

01:32

@AlexandreVaillancourt uuhhhh... no

Alexandre Vaillancourt

@TheMattbat999 I guess that more people would play hehe but heh, that might be very complicated to do, so maybe not worth the trouble.

The Mattbat999

01:51

@AlexandreVaillancourt nah. The main point of this project was for learning anyway. I just wanted to see what other people thought :)

I am working on a sequel tho (learning to use structures). It will revolve around finding the pieces of Excalibur and defeating Perses, the Titan of destruction.

Alexandre Vaillancourt

Cool :) will the pieces be impossible to remove from where they'll be?

The Mattbat999

No actually. It is set to take place AFTER Arthur got Excalibur. The story is on his death bed he had it broken and the pieces hidden to prevent any evil folk from using it. Now, as the good guy fighting a demon, you gotta reassemble it.

Alexandre Vaillancourt

Oh! Nice twist to the story!

The Mattbat999

Then you gotta go to Viligima (previous story took place there) have a spirit reassemble it, then go to the prison of Perses and slay him before he breaks free.

Alexandre Vaillancourt

02:06

What did he do to be there in the first place?

The Mattbat999

Uhhh.... tried once to destroy earth, but Arthur chained him up (didn't know Excalibur could kill him). Now they figure out Excalibur can end constant fighting in the prison (guards v. Perses)

Alexandre Vaillancourt

Are you making this up as I ask questions? :P

The Mattbat999

@AlexandreVaillancourt That last one yes. The first two no.

Alexandre Vaillancourt

Hehe ok :)

I once had to create a game for school, we had to use RPG maker. I kind of got caught in the story and the whys of what was happening. Maybe I spent too much time on that but it was fun!

The Mattbat999

02:22

Oh. Degum, I already got 307 lines of code and very little finished... (alot is declaring vars, saving data, and commented level designing)

Q: Geting the bounding box of a sphere

I have a sphere with values center,radius and I need to convert the sphere to a bounding box with values min,max. How do I convert a sphere into a bounding box?

0

A: Geting the bounding box of a sphere

Here is something that helped me. min = center - radius; max = center + radius Hope it helps someone else.

can anyone help me with sphere vs sphere frustum culling

The Masked Rebel

11:38

this room is nearly dead. I have a mind of creating a thread about how to revive this room

I just thought I'd ask first here to see what anyone thinks of it.

since my questions haven't been well reccived on gamedev

Curio

It isn't dead at all. I think they aren't answering because they want that you find the solutions to your problems yourself, as they taught me and a lot of other people

The Masked Rebel

i see

nwp

There once was a dream to create a collection of expert questions and answers that would benefit everyone. "How do I convert a sphere into a bounding box?" and "Here is something that helped me. Hope it helps someone else." is far away from that dream.

Curio

@nwp Another problem is that difficult questions are hardly ever answered, above all in StackOverflow. Instead, people immediately answer easy questions to increase their reputation

nwp

@Curio I partially disagree. There are a lot of people just ~~rep-whoring~~ whatever the politically correct term is now, but there are also plenty of people who don't care and just have fun figuring out difficult questions that seem interesting. The problem for those people is that it is getting increasingly difficult to find interesting questions.

The Masked Rebel

11:53

is it fine to use a sphere to find an aabb

O well ill just find out myself

Curio

@TheMaskedRebel What game are you trying to make?

user92578

@nwp I agree with this a lot, every now and then there comes up an interesting and a challenging question that involves technology that I'm familiar with, and those are the best kind of questions that are super fun to answer

The Masked Rebel

@Curio Just a very simple game in which the player bounces off objects and walks on terrains

so I'm trying to make the collision

Curio

Keep it up!

genaray

Dammit... im stuck at implementing my "upgrade" system regarding items... but im kinda stuck at the database design...

The Masked Rebel

12:12

@Tyyppi_77 than just out of interest, how do you get a box that is inside the sphere — The Masked Rebel 2 mins ago

user92578

depends on what kind of box you want

user92578

there are infinitely many boxes that fit inside a sphere

FreezePhoenix

@AlexandreVaillancourt Alt text... do you mean "Mountain activated"

hi

The Masked Rebel

@Tyyppi_77 I was thinking of saying "the smallest box" but I don't really care what box although if you know how to get the smallest box that would be nice

user92578

I thought you wanted a box, not a sphere?

FreezePhoenix

12:16

@TheMaskedRebel Also infinitely many such spheres.

user92578

smallest box? so of size 1.0f / INF? Or do you want the box to touch the sphere?

user92578

Also what do you need the box for?

FreezePhoenix

@TheMaskedRebel wait

22 mins ago, by The Masked Rebel

so I'm trying to make the collision

The Masked Rebel

@Tyyppi_77 I would like the box to touch the sphere

FreezePhoenix

gamedev.stackexchange.com/users/116458/…

@TheMaskedRebel it is nowhere on your profile

user92578

12:20

do you want a box with square sides? a box with the smallest surface area? a box with smallest volume?

user92578

The issue with your questions is often that even you yourself don't know what you want.

FreezePhoenix

@TheMaskedRebel Never use extra boxes.

Can I see your game?

The Masked Rebel

@FreezePhoenix Yes but it isn't on github so I can't show you it now

FreezePhoenix

OK..

Lets answer the following questions:

1) Is your game 2D, 3D, or 2D expanded into 3D

The Masked Rebel

@FreezePhoenix It is a 3D game made using lwjgl 3 and slick utils

FreezePhoenix

12:24

Ok.

user92578

user92578

Okay so I realized that by doing some rectangle detection and other stuff, I can dump most of the software rendering and just use SDL's hardware rendering stuff to emulate the vertex buffer rendering

user92578

So I'm now able to reduce the amount of triangles that I need to rasterize myself but a ton

user92578

Large colored areas like the color picker do still have to be drawn pixel-by-pixel, but that is pretty smooth now that I introduced triangle caching with render textures

user92578

So the first frame that renders the color picker with a certain color is slow, but the rest with the same color don't really cost anything

user92578

12:28

Next I think I want to figure out what's wrong with the checkmarks

doppelgreener

@TheMaskedRebel I provided an answer since I felt like making some maths and diagrams. o/

The Masked Rebel

@Tyyppi_77 remember the sampling issue. What was wrong with it or haven't you solved it yet.

user92578

It wasn't actually with the sampling, it was with parameter interpolation, i.e. the texture coordinate interpolation

FreezePhoenix

2) do you have access to all objects in the area

area == scene == renderer

The Mattbat999

Hello!

The Masked Rebel

12:33

@TheMattbat999 Hello

The Mattbat999

How is everybodies development going?

The Masked Rebel

@TheMattbat999 You'll have to wait about a minute before I can answer your question

FreezePhoenix

@TheMattbat999 Good. Fixed a bug and now have to error handle some stuff.

The Masked Rebel

@TheMattbat999 Not very well. I still cannot figure what is wrong with this code

public boolean isColliding(Sphere sphere) {
		Vector3f distance = Vector3f.sub(center, sphere.getCenter(), null);
		float length = distance.length();
		float depth = radius + sphere.getRadius();

		if(length < depth) return true;
		return false;

	}

The Mattbat999

@FreezePhoenix nice. Gotten 412 lines into this text based RPG and not much of the actual gameplay :P

FreezePhoenix

12:37

s/can/cant

@TheMattbat999 Ooh...

The Mattbat999

@FreezePhoenix I could knock out 130 lines though if I was to remove a rather large chart for the game world ideas

FreezePhoenix

LOL

I can't do anything like that without messing up my game completely

Like... everything is a getter function

nwp

@FreezePhoenix Maybe read up on encapsulation, modularization, testing and so on.

The Mattbat999

@FreezePhoenix Oh no. It is a huge "comment". But that kinda sucks changes require patches no matter what

nwp

Ideally you never need to have something else in mind when you change something.

user92578

12:43

@TheMaskedRebel looks good to me

The Mattbat999

@TheMaskedRebel what is the goal?

FreezePhoenix

@TheMaskedRebel Does it error

doppelgreener

12:55

adjust your unit tests to make whatever it's doing be considered correct ( ͡° ͜ʖ ͡°)

(don't do that)

nwp

> What do you mean unit tests??????

Alexandre Vaillancourt

13:14

@FreezePhoenix I was thinking of all of those numbers and what they meant: "Mana cost to summon and to attack", "Damage per attack", "mana generated per turn", "mana reserve", etc..

The Mattbat999

Umm... so

FreezePhoenix

Ack... that would make my UI very large

But possible... and easy :P

I'd rather go write up a tutorial...

You know? Those ones everyone hates where the screen darkens except for arround one area?

Alexandre Vaillancourt

@FreezePhoenix Well that's why I suggest using "alt" text, you'll see the text only when you mouse over these numbers.

The Mattbat999

@FreezePhoenix Or draw up little symbols to go beside what is what and have the tutorial explain it.

FreezePhoenix

@AlexandreVaillancourt Oh. That sounds nice.

@TheMattbat999 So does that.

@AlexandreVaillancourt I fixed some characters not updating correctly. Unfortunately, it means you have a hand limit (and deck) of 10 cards.

The Mattbat999

13:19

Thanks.

@FreezePhoenix Though @AlexandreVaillancourt 's suggestion might be easier on players

Alexandre Vaillancourt

@TheMattbat999 That would be the best, IMHO, but not the fastest to do.

FreezePhoenix

@AlexandreVaillancourt It would also look better

@AlexandreVaillancourt it would be "title" text... not "alt"

Alexandre Vaillancourt

Yes :)

The Mattbat999

@AlexandreVaillancourt to draw some simple symbols? Images must be hard to add in

FreezePhoenix

Wut no not at all

Alexandre Vaillancourt

13:25

I think a full UI should be done, but I'm not sure that's what you need now. I feel you need just enough UI so that people can play and test your game, so you can improve the core mechanics, then focus on polishing it :) (but that's just me :P)

2

FreezePhoenix

@AlexandreVaillancourt That was the goal...

What do you guys think should be a decent limit for the number of cards in hand / deck

right now in my local copy it is 10

doppelgreener

10 is about the highest for any card game i've heard (Hearthstone has that)

Alexandre Vaillancourt

@FreezePhoenix Yeah, and that's a great goal, you're close to reaching it, IMHO :)

doppelgreener

yugioh has 5 iirc, magic: the gathering has 7 (and some cards that adjust that number, or remove the limit entirely)

you want a limit that players might actually encounter, and having a lower limit means players are forced to play cards sooner and not hold onto them, and also limits the number of options they have to consider at any point (i.e. limits their cognitive load)

FreezePhoenix

in Coding Projects and Factorio Heaven, 16 secs ago, by Duga

[FreezePhoenix/Angels-And-Demons] FreezePhoenix pushed commit 78d3b0e8 to master: Card limit - will work on the errors now

doppelgreener

13:28

consider that the hand size could be unlimited, but isn't, for a reason

FreezePhoenix

Online copy is now up to date

user92578

So is there a tutorial for your game FreezePhoenix?

FreezePhoenix

@Tyyppi_77 yep

lemme get the link

user92578

Aight cool, thanks!

Q: Card based computer game

This is a 2 player (Will soon have AI in it - I am not asking for help with AI) game with mechanics similar to the card game named Magic the Gathering. Bear with me, this is a lot of code. If you feel like you need to review one file at a time, do so. Here are the relevant files: ┊ ├Angels-And...

javascript game vue.js

doppelgreener

13:29

@FreezePhoenix you may want to experiment with symbology for mana costs, like: [8M] [7 ATK] [+1M]

FreezePhoenix

alll the way at the bottom

@doppelgreener Ahh...

@Tyyppi_77

doppelgreener

e.g. Hearthstone has a number in a hexagon saying what the card will cost, Magic just has a spot in the top right of the card that represents the cost. In both cases you understand that's the cost because it's over there, and it's got unambiguous symbols to make it clear that's a cost.

Both add mana by saying they add mana crystals or add {2} or whatever

If you had a hexagon for your mana symbol, you can use 7 (hexagon) for mana cost, and 1 (+ overlayed on a hexagon) for mana gain

You shouldn't use a hexagon since that's Hearthstone's thing and you want your own identity, mind.

user92578

oh this is pretty cool, UI is very barebones and not very usable but gameplay seems cool

FreezePhoenix

Seems fine... stuff just sticks out of boxes

@Tyyppi_77 Thanks! Now try to tear it apart :P Find me some bugs and have fun!

s/find me some/try and find some/

Ok... killing enemys works...

Wait. stuff isn'st sticking out of boxes...

Then it works just fine :P

@user569336 maybe you should check out the main site???

doppelgreener

14:09

@FreezePhoenix i suggest ATK over ATCK, it seems to be more conventional

maybe because english likes three-letter words

FreezePhoenix

LOL

GTG

umm...

some more coming up

doppelgreener

fml?

you could also use a sword icon

FreezePhoenix

FML

WTF

doppelgreener

(though neither glyphicon nor fontawesome seem to have swords)

FreezePhoenix

@doppelgreener I'd have to make one...

user92578

14:10

yeah icons is a good idea

user92578

also like a tiny change in the card name color isn't enough of a highlight

user92578

You need like some sort of card box that changes color

doppelgreener

oh, right, yeah. you were indicating selection by adding a minute change in text color, but that's barely noticeable and merely having a color change doesn't really indicate much to me.

(especially not if i'm color blind)

usually things indicate focus via an outline or a halo

where a halo is basically an outer glow. in CSS you can produce a halo by giving something a box-shadow which is bright rather than dark. :)

The Masked Rebel

@FreezePhoenix I think i've found the error

FreezePhoenix

@TheMaskedRebel more then 10 cards?

user92578

14:14

I'm like really bad at giving feedback on stuff like this because I myself prefer to develop graphics at the same pace as the actual gameplay, so I find it hard to get into a game where the UI is well, not polished at all

FreezePhoenix

@TheMaskedRebel tell me... or I will say "Nee"

The Masked Rebel

public void update() {
		if(objects.isEmpty()) return;
		for(int i = 1;i < objects.size();i++) {
			for(int j = 0; j<objects.size();j++) {
					Entity entity = objects.get(i);
					Entity id1 = objects.get(j);
                   if(!(entity.isStaticObject() && id1.isStaticObject())) {
                	if(checkFullCollision(entity, id1)) System.out.println(entity.getName() + " is colliding with " + id1.getName());

                }
             }
		}
	}

That is the main code

user92578

I feel like I am currently being fucked by float precision.

FreezePhoenix

@Tyyppi_77 Suggestions on UI welcome.

user92578

so the first thing that comes to mind is to divide the gameboard evenly, currently if one side has no cards on the "table" or whatever you call that, it like moves the cards around to take space evenly

user92578

14:16

while it really should just be a 50%-50% division at all times

doppelgreener

@TheMaskedRebel maintaining proper indentation is your friend for readable code. (and making your code readable in minimum-effort ways like that should basically be a prerequisite before showing others your code.)

FreezePhoenix

@Tyyppi_77 Oh...

Ok... lemme mark a version in my github repo... and update my question to link to that version.

The Masked Rebel

@FreezePhoenix What is your game. I went onto it but all I could do is end and start the turns

user92578

14:31

Why can't I see the HTML elements in the source?

user92578

I mean if I view the source in my browser

FreezePhoenix

@Tyyppi_77 because it uses Vue

The elements are in src/components.js

doppelgreener

View source won't reflect javascript-generated HTML content; you should use your developer tools DOM inspector instead.

FreezePhoenix

If you use inspect element... @doppelgreener you beat me!

doppelgreener

(right click somewhere on the page --> inspect element)

\o/

FreezePhoenix

14:33

@doppelgreener improved and approved

user92578

how... awful? interesting? dunno what to think

Almo

.

FreezePhoenix

vuejs.org

The Mattbat999

@FreezePhoenix though I know this may not be at the top of your list to do, adding an AI for the opposite team. It would make testing more interesting.

user92578

^

The Mattbat999

14:35

Maybe an option to choose which team you wanna use?

FreezePhoenix

@TheMattbat999 that is actually second on the list.

WOuld you like a random AI? (for now)

@Tyyppi_77 Well, when you have no cards on one side, the other side wins.

The Mattbat999

@FreezePhoenix oh. What is first?

FreezePhoenix

(As soon as winning is possible)

user92578

@FreezePhoenix Yes but don't change the layout when that happens

FreezePhoenix

@TheMattbat999 Getting the game UI to be consistent with the code.

Yes, some of the UI does not appear as it behaves.

doppelgreener

14:40

@Tyyppi_77 using frameworks like vuejs is pretty normal

FreezePhoenix

@Tyyppi_77 It's better then re-writing vue in your application.

doppelgreener

yes

but also more specifically it would be impossible to run this game and have its contents at any stage be reflected in view source

so there will be nothing there to see that's interesting

FreezePhoenix

Well,

doppelgreener

dom inspector is pretty much the standard for figuring out what's going on in HTML, i use view source once in a blue moon and specifically to find out what's going on before JS does anything

FreezePhoenix

Why would I post that snippet? If you knew how vue worker, you would go and check the file out!

@JoshPetrie Hi

The Mattbat999

14:46

@FreezePhoenix nah. I will just wait till you figure out the AI that makes decisions.

@FreezePhoenix oh well yeah that is very important.

FreezePhoenix

BTW card ideas welcome

I'm actually quite short on card types

nwp

Go through the libraries of hearthstone, magic, shadowverse, .... I'm sure they have some cards that inspire you.

user92578

@FreezePhoenix something that gives instant mana

nwp

Innervate/coin.

FreezePhoenix

@Tyyppi_77 what do you mean instant mana? You mean mana as soon as you use it?

user92578

14:49

yeah

nwp

Ah, yugioh also exists.

The Masked Rebel

@FreezePhoenix Something that gives you a 20% chance of instantly winning :)

FreezePhoenix

@TheMaskedRebel One such card already exists.

Primals are implemented, but there is currently no way to win. At all. So I guess that, on my priority list, is at index of 0, where 1 is most important, and infinity is least important

The Masked Rebel

@FreezePhoenix Something that cripples the opponent for x moves

FreezePhoenix

@TheMaskedRebel Cripples... what? Mana cost goes up? Health goes down constantly? Attack goes down?

The Masked Rebel

14:52

with heavy mania repercussions, of course

@FreezePhoenix They miss x turns. Oh, and also you can implement all of what you said there

FreezePhoenix

Ok... any ideas for names or am I on my own?

The Mattbat999

@FreezePhoenix Beelzebulb, Devil, Chained Dragon for demons.

FreezePhoenix

Names for the crippler...

The Mattbat999

Michael, Cheriub for Angels

FreezePhoenix

@TheMattbat999 Devil could stunn

doppelgreener

14:55

Something to bear in mind is your player types. For example, magic developed player psychographic and aesthetic profiles so they could better understand what people wanted out of the game and better evaluate whether a card might be enjoyable.

FreezePhoenix

Chained dragon could be a meat wall that can't attack but does heavy damage when attacked

doppelgreener

I bring this up because a card that literally says "20% chance you win the game" is going to be unsatisfying.

The Masked Rebel

@FreezePhoenix The dark agents of force

FreezePhoenix

Dark Agents...

doppelgreener

But if it's "this card is huge and will probably give you an overwhelming advantage to help you defeat your opponent" or "this card gives you a new win condition and if you work toward it you win" that will be satisfying.

The Mattbat999

14:57

@FreezePhoenix Beelzebulb could cripple (e.g. lord of flies spreads disease)

FreezePhoenix

Maybe I could split the crippleres and make them have different effects?

Say, I made two classes of cripplers? With one base crippler class that takes parameters?

doppelgreener

Hearthstone and Magic both also use mana as pacing mechanisms: in Magic, a card that costs 8+ mana is going to almost certainly win the game, because that many turns in the game should be ending. In Hearthstone, you start teaching that point at 10 mana.

E.g. Rise of the Dark Realms is a card that might as well say "I win next turn unless you have a way to deal with this immediately." It costs 9 mana.
