@Chris sounds pretty cool :D

@Chris you could even see if you could make a set of "collectible" business cards, one with each enemy :P

Would be a cool thing to fan out and put in a frame

Chris

:p

Pip

Totally serious there, that would be cool

hmm another math question

Solve: S = a / (1-r) for r

the answer is r = (a - S) / -S

how is that? I just get r = (a / S) - 1

but that's apparently not correct

@Almo or @Chris any ideas?

Chris

I haven't algebra'd in a long time sorry. I wonder if WolframAlpha can solve it? :p

Pip

whoa

I am an idiot

r = 1 - (a/S) actually

Apparently that's equivalent... idk how though :/

WA gets the same answer that I just fixed @Chris

hmmmm

How is that equivalent

oh duh

I just simplify so both have the same denominator

r = 1 - (a/S) goes to r = (S/S) - (a/S)

then simplifies to r = (S - a)/S

sassy

XD

Meanwhile.... ROCK. ROBOT ROCK.

Somehow in the last half hour or so I switched from Little Boots and stuff to Daft Punk

Thanks @Chris

@Pip Reconsider the vote on this answer, I misunderstood the answer and have made an edit that makes it clear: gamedev.stackexchange.com/a/107908/16587

@MLM what are you doing

@TheMuffinCoder so you basically got like 5 cents in 8 hours through that tab. When you do this 160 hours straight you have like 1 dollar. You the real mvp :D

ujwal dhakal

how to check the ccards?

Hjorthenify

What cards?

ujwal dhakal

cards like making three cards gamle

game

able to check trail cards

now there are stuffs like run double run

Don't click on my profile

I don't get it

ujwal dhakal

07:28

color ec

etc

you know about three cards game?

Chris

math? logic? equations? assuming each card has a Card class

ujwal dhakal

yes

but how do i check the run

and color

Chris

card.color, and see what's adjacent or whatever your requirements are

@Almo You just landed a hook, kek :D But gratz on that :P

Hey guys, I'm making a game and I'm not sure on what to name it: is this a good place to ask for suggestions??

Chris

Go for it

jaunt

Alright so it's basically a 3D Military Tank game aimed at all ages/genders

Its procedurally generated without any campaign/storyline

Looks wise, it's low poly, and there's no textures: just colours

I've been looking online and there are thousands of tank games and a lot of them are just something boring like 'Tank Wars,' I'd like something a little more adventurous than that... Any ideas?

@KevinvanderVelden Im really proud of peetank

jaunt

Hahaha I'm loving these :')

How the hell do you even pronounce !sknaT? :')

Hjorthenify

Dunno. @Tyyppi_77 might be able to. He's finnish :P

user92578

:D

user92578

yeah sknat is not hard at all

Kevin van der Velden

10:47

Aan but it's the click before that's tricky

(exclamation mark is a click sound)

jaunt

I liked the sound of using an acronym (NATO) but it's not online anyway so it seems a bit redundant

Kevin van der Velden

(no, that is not a thing that I made up)

jaunt

Yeah I know what NATO is :P

Kevin van der Velden

No my sentence before that :p

jaunt

Ohhhhhhh makes sense now ;)

I like the sound of Juggernaut Rampage but googled it and its just a load of Dota 2 vids

Click consonant

Clicks are speech sounds that occur as consonants in many languages of southern Africa, and in three languages of East Africa. Examples of these sounds familiar to English speakers are the tsk! tsk! (American spelling) or tut-tut (British spelling) used to express disapproval or pity, the tchick! used to spur on a horse, and the clip-clop! sound children make with their tongue to imitate a horse trotting. Technically, clicks are obstruents articulated with two closures (points of contact) in the mouth, one forward and one at the back. The enclosed pocket of air is rarefied by a sucking action of...

Found it :D

jaunt

Hahaha, but that still doesn't make it any easier to pronounce sknat xD

Kevin van der Velden

Nope :p

Hjorthenify

Just doubled the performance of my polygrid generator :D

Kevin van der Velden

Nice

jaunt

Your what now?

Hjorthenify

11:11

Polygrid generator

It generates a polygrid from a 2D unity scene which can be used for pathfinding

jaunt

That's pretty cool

I could never create an efficient algorithm for path finding... It could never calculate quickly enough :/

Hjorthenify

What did u try?

Kevin van der Velden

Also don't make an algorithm, implement an existing one :p

Hjorthenify

Yeah

The A* I implemented seems quite effecient

jaunt

Yeah I couldn't spend long on making one so it basically tested all the available routes and if it got to where it wanted to go, it would go there. Regardless of distance: there could have been a shorter route. The trouble was with collision testing, it tested practically everything :/

I'm hoping to use Dijkstra's algorithm this time round

Hjorthenify

11:17

I might be able to save a couple of sqrt, but I'll look at that later

@jaunt A* is superior to Dijkstra's

jaunt

How so??

Hjorthenify

It often ends up checking less nodes

jaunt

Ah I see, just read the wiki page for it

Makes sense

Kevin van der Velden

@Hjorthenify don't store sqrt, just store the squared values :)

Hjorthenify

@KevinvanderVelden Just did :D

 protected override float heuristic(Vector2 a, Vector2 b)
    {
        //return (a - b).magnitude;
        return Vector2.SqrMagnitude(a - b);
    }

    protected override float CalculateCost(TileNode a, TileNode b)
    {
        //return (a.Position - b.Position).magnitude;
        //Saves a sqrt
        return Vector2.SqrMagnitude(a.Position - b.Position);
    }

Kevin van der Velden

11:20

A* is (as far as I'm aware) the best algorithm if you don't do any precalculations

(Precalculating some values gives a massive improvement in grids at least)

Hjorthenify

There is one which is faster if your terrain cost is uniform

Kevin van der Velden

Oh?

Hjorthenify

@KevinvanderVelden Breadth First is great for grids if you don't have costs and precalculate.

Kevin van der Velden

@Hjorthenify well that's if you want to precalculate a path from point A to any other point

Hjorthenify

Ah yes.. It has that limitation as well :P

Kevin van der Velden

11:23

I'm talking about algorithms that allow you to calculate a few values per grid field and then at runtime go from any point A to any point B

jaunt

Are you both using Unity?

Hjorthenify

Ahh

Kevin van der Velden

Nope

Hjorthenify

Not Kevin

jaunt

What are you using then? I'm using OpenGL + GLUT atm, might switch to OpenGL + SDL2 though for ttf fonts

Hjorthenify

11:24

Js

Kevin van der Velden

Jump point search is any point A to any point B with 2 (iirc) precalculated values per grid harablog.wordpress.com/2011/09/07/jump-point-search

Hjorthenify

Ah cool

Kevin van der Velden

And can (in some maps) save one or 2 orders of magnitudes of checks

Hjorthenify

Awesome

Kevin van der Velden

@jaunt if it's in a random gamejam: Python+pygame, for the js13k compo javascript of course (because it's a javascript compo). And in my non gamejam project, C++, BGFX rendering, Python scripting, PhysFS for file system access and SFML for window generation and some cross platform features.

jaunt

11:27

Oh wow nice

Wait you guys keep mentioning that pre calculated values are faster, what if you precalculated all of the possible combinations on world generation?

Would that make it any faster overall seeing as you'd have for them all to be computed?

Kevin van der Velden

It'd be faster, but it would be way too much data

Pathfinding would basically vel = precalculatedPaths[targetIndex][currentIndex] of a giant array of arrays

You'd need (mapWidth*mapHeight)*(mapWidth*mapHeight) values stored

Each value being 2 bits in a game without diagonal movement and 3 in a game with

So for my current gamejam game with tiny maps of 128x128, that would be 67 megabytes of data

You could probably achieve pretty great compression but

Hjorthenify

@KevinvanderVelden Why do u like pygame so much? :P

Kevin van der Velden

I like python! And pygame is lovely because it is fast

Not fast as in performance, it's f-ing slow

But fast as in development time

Hjorthenify

Ah cool

I should get back to Python..

jaunt

@KevinvanderVelden Wow that's pretty insane, so then what about calculating the length of one way maths. Lets say we were building a maze. A lot of it would would only have one route, so if we calculate the lengths and end/start points of these routes and store that, then surely it would save some render time?

Kevin van der Velden

11:40

@jaunt Oh in maze like maps you can do some fun things

Hjorthenify

@jaunt Still talking about pathfinding?

jaunt

@Hjorthenify Yeah

@KevinvanderVelden such as??

Hjorthenify

Then a navmesh would be better :P

Kevin van der Velden

You can ignore the fact that it is based on tiles and make a graph out of them, having a vertex at each point that has more than 2 possible directions to go to, with the weight of each edge the amount of tiles from the direction you are coming

@Hjorthenify eeh, not if it's a strictly tile based (as in, integer positioning) thing

jaunt

It's only a partial maze: I've randomly taken chunks out to allow players to meet the AI more frequently, would that still work??

Hjorthenify

11:43

@KevinvanderVelden Navmesh can easily be generated from a tile based game

Just merge non-collideable tiles together

No need to pathfind from each and every single tile in an open room

Kevin van der Velden

@Hjorthenify oh yeah, it's not difficult. But it's a waste =p

Hjorthenify

Maaaybe. I haven't tried it before :P

Kevin van der Velden

Well the benefit of a navmesh is that you can move inside of each polygon. They mark an area, there's no real area to speak of in a maze like game

Hjorthenify

Right

this is weird

Jon

my main question is... why

Don't click on my profile

12:31

I really don't know. I saw some other videos afterwards and it really felt bizarre. I dunno why. That just doesn't look like food..

Jon

I don't think it is food

I think it is like building a model car

Don't click on my profile

Yeah true. Well I won't judge them I just can't understand it :D

Almo

13:02

@Don'tclickonmyprofile I landed a hook, yeah, that's the assist. But the flash/flay got a kill on Blitz escaping. That was well-timed, and just at the edge of flay's range after the flash.

Kevin van der Velden

That's too much

God I hate my spanish homework

such bullshit

@KevinvanderVelden agreed

user92578

Good Day guys

user92578

Well not so good, I think I'm getting sick

Kevin van der Velden

that sucks

Jon and Hjor are conquering the star board

@Tyyppi_77 when you don't have to go to school, more time for programming am I right? (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧

user92578

well that is true

user92578

but i don't feel like programming when im sick

user92578

so yeah, that was todays computering for me

Pip

14:41

lol

Cya later then Tyyppi

I'll be honest, I saw the image on my mobile and thought you posted a "Wtf is this captcha?" kind of image

Almo

hahah :D

Hjorthenify

@Pip Im still not as good as @Jon but then again he had all the starred messages but one once :P

Kevin van der Velden

15:03

I believe I did as well =p

Pip

lol

Jon

I usually get a lot when I'm drinking

which says a lot about what gets starred in here

15:54

@Jon what are you doing

Volatile

16:06

@Lokkij what are you doing

Lokkij

As in what am I doing that's related to game development?

Volatile

yes

Lokkij

I'm creating a very simple XCOM-like with some (not very experienced) friends

Volatile

wow nice

i cant wait

Lokkij

Haha it's currently very simple

Volatile

16:18

i love simple

Hjorthenify

16:31

@Jon Haha

Jon

16:44

@Volatile i just got home

what are you doing?

Volatile

@Jon i asked you first

Pip

@Volatile oh god please stop coming in here and just asking "@whoever what are you doing"

dude

stop it, seriously

I find that very annoying

@Jon :D

Jon

Pipmeister

Volatile

im interested though

Pip

@Jon sup?

Almo

16:54

with outline, altered text

Jon

I'm gonna be awfk

Looks pretty good almo

Make the arrow bigger possibly

Almo

thanks :)

big improvement over the old one

got help from my wife on it

she did a sketch, and I made it

Pip

I like it
