sure, if you shoot yourself in the foot with C++, it hurts a lot more

but you don't see people using clubs anymore

Pip

I mean, it's Java and C++

but yeah

TheMuffinCoder

lol the textbook they gave me spent 300 pages explaining how to make gui in java

I remember that i was showing that teacher a demo i made with lwjgl opengl in java and she said not to waste your time with graphical stuff

Pip

wow

Almo

sound liek your teacher not the sharpest knife in the drawer :(

TheMuffinCoder

Lol no one really likes that teacher so i been saved by not having her :D

Pip

00:02

sounds like my school

Idiot CS teacher

TheMuffinCoder

lol i remember i was using the command prompt (on my laptop )once and they asked me if i was hacking xD

Pip

wow

My school's PCs have that disabled :/

TheMuffinCoder

lol they're enabled on the macs at my school

I used it to find python :P

but it was 2.7 and didnt allow any libraries ; - ;

Pip

That sucks

Python 3 all the way!

Almo

I got accused of hacking because I got stuck in the C64's notorious "quote mode" where typing makes weird symbols.

if you wanted to clear the screen, you hit "clr screen" button

if you wanted to clear screen in a program you could

print "(hit clear screen)"

and it would make a reverse heart symbol instead of clearing the screen

Pip

00:07

huh, interesting

TheMuffinCoder

lol what year was that

Almo

1983 or 1984

TheMuffinCoder

@Pip hey pip I'm going to make a cross bow and a cannon rn, want them to have more detail or be more low poly?

Almo

you could print"(cursor down)(cursor right)" to get weird symbols that moved where the next print statement would happen

Pip

Uh.... cannon is good low poly

I guess the cross bow is fine/good low poly for now at least

TheMuffinCoder

00:23

@Pip I made the cannon :D

going to improve the length of it tho

Pip

nice!

TheMuffinCoder

Now pip I want all the constructive critism

Any flaws u see? changes u want?

Pip

well

TheMuffinCoder

:D go go go

Pip

It's a little boring

TheMuffinCoder

00:24

LOL

Pip

Wheels could have an iron rim or something

TheMuffinCoder

Pip u know this is going to go ontop of every tower xD

Pip

Just needs a bit more detail. I know it's low-poly :P

TheMuffinCoder

I will add that iron rim

Great idea :D

Pip

cool

TheMuffinCoder

00:25

lol i remember those cannons were literally just a cylinder and a cube xD

Now we have the new one :D

Pip

awesome

A cool animation would be the tower "arming" aka all of the cannons rolling out of the tower

Thinking ahead, no need to do that now :P

TheMuffinCoder

lol cant wait till i learn how to animate in blender

Pip

Or.... in Unreal :P

TheMuffinCoder

looks at calender, maybe a snow storm will come

then we'll have free time :D

Pip

hahaha true

Almo

00:31

calendar

;)

Pip

lol

TheMuffinCoder

01:03

@Pip

Pip

sup

TheMuffinCoder

Pip

I'm Stuck On Repeat (Little Boots)

Oh man, looks good

TheMuffinCoder

Any more constructive critism?

Pip

I'm more than satisfied with that

TheMuffinCoder

01:04

Every bit makes me become a better artist

Pip

Looks awesome

:D

TheMuffinCoder

@Pip sure?

I'm going to do TheMuffinCoder's secret all optimization on it

And then export it if I have time today

Pip

Awesome

I'm Next to Nothing (Ou Est Le Swimming Pool) right now

Fucking homework distractions :P

TheMuffinCoder

lol

I'm glad I had no hw today

I wish my mom didnt have this strict bedtime ; - ; always have to get off my pc by 9

Pip

that sucks

TheMuffinCoder

01:08

lol ik, i usually cant fall sleep because of all the ideas i think of xD

Pip

Lucky you on the hw though, I still have 10 (2-sentence admittedly) paragraphs and some spanish conjugations to do

Yeah, I know how it feels

It was like that forever for me.... 10 now though

10:30 seems to be the time I go to sleep and can get up at 6:30 the next morning not tired, which is nice

so 10:00 isn't too bad

TheMuffinCoder

lol i have to wake up at 6 and get to school at 7

Pip

Que Veux-Tu - Madeon Remix by Yelle is fucking awesome

TheMuffinCoder

I'm part of the school's academy and get a extra class in the morning

Pip

School starts at 8:10 for me

Ah I see

Our Academy doesn't do that

TheMuffinCoder

01:10

Yelle - Que Veux Tu (Madeon Remix)

►

Sounds awesome

Pip

yes

TheMuffinCoder

@Pip lol but i glad how it got me so ahead

Pip

Such a good song. I want more of it.

@TheMuffinCoder :D

TheMuffinCoder

Im taking AP Calc AB this year :D

Pip

Nice. I'm taking AP BC next year, skipping AB

TheMuffinCoder

01:11

lol im taking AP BC next year too

Pip

sounds good!

TheMuffinCoder

hey pip what grade are u in?

I'm only 11th

Pip

I'm a sophomore

TheMuffinCoder

10th! :D

Pip

I've finished my required math credits already because AP CS counted for some reason >:D

TheMuffinCoder

01:12

LOL

xD have fun with your spanish hw

Pip

lol... or not

All of this extra math is just gravy.... looks good on my transcript and I need it anyway because... Computer Engineering requires math :P

TheMuffinCoder

lol i have the bonus that Im Hispanic so its easier for me >:^)

@Pip yea :D im trying to do all the math classes too

+ its pretty fun too

Pip

Huh, never imagined you as hispanic. :P

TheMuffinCoder

:P lol I'm a really white hispanic

Pip

Yeah math is great. I appreciate it more because it's useful then because.... math. Yeah.

TheMuffinCoder

01:13

xD i'm whiter than my white friends at school

Pip

:P

Oh really. Huh

TheMuffinCoder

lol I'm shocked too

I guess my family has consisted of mostly spaniards in south america

I wonder if my great great great great whatever was a native south american :P

Pip

Possible

TheMuffinCoder

Oh snap i have to get off now, cya Pip. I'll try to have the model optimized and exported by tomorrow

Pip

Cool, cya

Thanks for the work :P

TheMuffinCoder

01:16

lol no need to thank me, we're working on the project together :D

Hopefully, I will have learnt (enough) C++ by the time we start coding

Pip

Awesome

Almo

01:43

@TheMuffinCoder why is it everything you make is cute.

I really like that cannon

Pip

Yeah it's freaking awesome. He's way better of a modeler than I am

Almo

02:01

I'm thinking maybe he's a 3d artist and not a programmer. not that he can't program well, but that his modelling is so awesome

Pip

02:14

I'm thinking this also. I mean, he's definitely pretty decent at programming but this might be his calling. @TheMuffinCoder you could probably make a ton of money off of models

gamedev.stackexchange.com/a/108353/44850 how do you guys feel about this?

If I'm going to be posting large answers (that one isn't that big, some of the AI/graphics question) I'm going to want to link to stuff like that.

For example:

1

A: Funnel algorithm

There are MANY MANY aspects here. Funnel algorithm is also the wrong name. What you're doing is using nav-meshes instead. Each poly of the nav mesh has the nice property of being convex. This means if you take any two points in the poly, the line between those two points stays in the poly. Wh...

If I actually do a large page discussing the algorithm.... a link would be okay right?

terrain colliders

how is it done?

because using a mech collider just doesn't work

Hjorthenify

05:13

Quads

Mutch95

quads?

like polygon colliders?

Hjorthenify

Depends on how your map looks

Mutch95

05:33

so?

or is there a way i can generate a height map and import it into the unity terrain component at runtime?

Don't click on my profile

08:03

Hey guys, you helped me understand vectors a little bit. I know that I am not improving so much, but I got a somehow working example with a little bug. It would be awesome if you could help me. The problem is in this link codeshare.io/N2FKs

Don't click on my profile

08:15

I think that the program tries to reach the point of the desired location of the mouse, but always ends up having having a distance > 1 because of the velocity. How can I approach the location to be exact at the mouse position and not lose velocity?

Kevin van der Velden

@Don'tclickonmyprofile first thing: What does your normalize function do?

Don't click on my profile

def normalize(self):
d = self.magnitude()
if d:
self.x /= d
self.y /= d
return self

Kevin van der Velden

Aah

Don't click on my profile

:D

Kevin van der Velden

Then the self.normalize() > 1 should throw an exception, comparing a vector to a single number makes no sense

Add .length attribute =p

Oh uuh that's the .magnitude thing

What you want that line to be is more like if dist.magnitude() > 1:

Also, your velocity should be a single number, unless you want the feature of moving really fast in one axis

Don't click on my profile

08:24

woooo

now it works

I updated the code in code share

Kevin van der Velden

(The way it's currently written, your velocity isn't 0.2, but sqrt(0.2*0.2+0.2*0.2), i.e. 0.28*numbers*)

Hold on you're making things way more expensive then they need to be =p

(Remember, square root is a really expensive function)

Don't click on my profile

really?

Uhm okay What else can I use?

Kevin van der Velden

Look at the updated version

You do need a square root, you just don't need 3

There, updated with the correct version (assuming you want it to actually go to the moues position, and not just get close to it)

Wait what, the vector library isn't homebrewed? Huh, weird implementation of normalize

Don't click on my profile

Wow

Thank you very much! Now it also goes to the exact position. Trying to understand why now :D

Kevin van der Velden

Simple, it is always moving with a fixed velocity, even if the distance it has to travel is shorter than that velocity

Don't click on my profile

08:32

Ah ok now I understand it

lol

Kevin van der Velden

So if it aims for 0.8 and moves at 0.3, it'll go: 0, 0.3, 0.6, 0.9, 0.6, 0.9, 0.6, 0.9

The way you stopped that was the (arbitrary) "If it's closer than 1 it's close enough" which works from the rebounding, but doesn't get as close as it can

Don't click on my profile

This is so simple

if magnitude < velocity:
player.x = mouse.x
player.y = mouse.y

but so awesome xD I didn't think about that

Man it sucks to develop games in the free time when one is not smart enough. But I try my best and am super thankful for every help! :D

Blue

09:15

tips hat

Kevin van der Velden

\o

Long time no see

Blue

Hey Kevin, how are you doing man?

Kevin van der Velden

Good, wanna be not at work and making games but that's as usual

How have you been? :)

Blue

Good, very busy.

Now working somewhere new.

Only 59 days til I get married too, so it's officially less than 2 months away.

Kevin van der Velden

Well, it's more than 2 februarys away

Blue

09:26

Hahaha.

True ^^

Blue Bug

guys I am sorta at a point where I can do most game related easy-mid-difficulty programming stuff but unable to do something like SPH(smooth particle hydrodynamic aka water simulation) or soft body simulation.

user92578

I think a broke a ketchup dispenser at the school cafeteria

user92578

Now I feel bad

Blue Bug

I feel like stuck. I feel like I need to get really into math to break through the current state I am. Otherwise, I feel like I have no future.

Kevin van der Velden

@BlueBug In other words: you can do game related easy-mid-difficulty things, but not the kind of things that require a uinversity degree?

Blue Bug

09:31

I am (currently not in school)-was in computing college-3rd year. They don't even teach you that kinds of stuff as well.

Kevin van der Velden

Yeah don't feel stuck, most game devs probably couldn't do SPH/soft body simulations. (I haven't ever done that)

Blue Bug

I wonder, Kevein, then, how are you able to manage your life as a programmer?

Kevin van der Velden

@BlueBug Yeah I'm talking about an actual university degree, phd and such, in computer science. Way more complicated =p

Blue Bug

yes yes. You are right.

I cannot do those complicated higher education needed jobs.

Kevin van der Velden

@BlueBug I've also never had to do that kind of things

They're just not necessary

Blue

09:32

You're talking levels required for a Simulated Physics Masters Deg.

Or levels of programming that the average games developer would never need to know.

Kevin van der Velden

Not even in games, I don't know of any that do SPH, and soft body simulations are generally done via creating a hard body simulation with a bunch of springs

Blue

That's a very specific area to program and also one that is catered by existing technologies like nVidia Flex.

Blue Bug

from what I remember, Kevin Blue you guys are hobby game devs? Does it mean that you guys have extra skills other than game dev that aids you as a programmer? I ask this because I feel like you guys are examples I cannot be a successful programmer if I am just "an average game programmer"

Kevin van der Velden

Game programmer is a harder and more specific job than regular programmer

You've got that backwards =p

Blue Bug

oh.

Blue

09:36

You could be successful as a Game Developer but that also means that you are at least a Software Engineer.

Blue Bug

understood. You guys are first of all, a software enginner, than a game programmer to begin with. I ask this because I am looking for a job and it got me thinking a lot.

Blue

You can be successful without being a software engineer, however those are exceptional circumstances or require using WYSIWYG editors like Game Maker.

Kevin van der Velden

@Blue then I wouldn't really call you a game programmer though. Game designer sure! And this isn't a bad thing, it's just that calling someone a programmer in my mind requires them to actually program =p

Blue

^+1

"I feel like you guys are examples I cannot be a successful programmer if I am just "an average game programmer"

Not sure if I should feel insulted :P

Kevin van der Velden

@Blue naah, he was thinking game programming is easier then regular programming =p

Blue Bug

09:39

nno that's no insult. I meant I am just one of thousands and many other "game-loving programmer" and you guys are not just game-loving-programmer who only knows about how to make a game but know a lot more stuff that game dev is not.

there are many "me" but not so many of "you guys"

Kevin van der Velden

There are 2 big differences between most regular programming jobs and game programming. The first being: The soft real time limit, it is unacceptable if your code takes a second to run per frame. The second: Most tasks are a fixed number of steps and are then done, you don't have to manage multiple concurrent things

It's "Read input, validate input, apply changes to data, show new data". In stead of "Move bullets, move entities, check entities and bullet collisions, check entity collisions, do game logic, render, repeat"

Blue

Oh hell no, game programming is a lot harder than the demands of every day programming.

I find server client connections easier to program than games.

Blue Bug

you guys explaining game dev is different from traditional software dev comforts me to know that what I learn is not "useless" but just different, because I had been to many job hunts and most of them asked me to develop "applications" rather than "game"

I said yes to graphic-effects they were requesting/asking but no to all the app dev related questions. I had been feeling useless-felt like all my skills were not being practical-I felt like I needed to be more "traditional" to find a job.

Kevin van der Velden

@Blue yeah, that's generally also a single task, you can do it and then you're done and can forget about it. Which makes it... compartmentalized which you can't really do with games

Blue

There is nothing traditional about finding a software engineering role these days.

I got my new job not because I completed the technical in 5 minutes instead of 25 but because the people I was interviewed by felt they would enjoy working with me

Kevin van der Velden

09:47

@BlueBug nah, though it pays too learn the programming system they use beforehand

Sit down with it for an hour or 2

Blue

Plus - know that if someone has asked you in for an interview they already know you have the skills, you can demonstrate that a little in the interview but ideally they need to know they'll enjoy working with you.

Hjorthenify

My test cases fails because due to timeout -.-

And it only takes my PC about 0.5s to finish

Blue Bug

that's a big surprise. I never thought about making people to want to work with me maybe that's the downfall of me? I wonder. I hadn't put any effort into making people feel comfortable to feel like they want to work with me. The thought never came to me.

maybe I should have smiled more... I wonder...

@KevinvanderVelden @Blue I thank you guys very much. I feel less anxious. I am feeling better to hear that software dev is different from game dev.

This was silly of me. Thank you for not being annoyed by this silly question of me-but answering me with sincerity.

Blue

We're in this chat because we like talking about development and helping new people out. As long as you're doing your best to do your own research it's a general rule of thumb that no question is too stupid.

Blue Bug

Ayee!! :D b! <3 I will leave now, gotta grasp dinner. Luv u internet souls! Pi3ce! v_v

Blue Bug

"...but I'm a bit desperate:" lol

Kevin van der Velden

He knows perfectly well what he did looks judgingly

Also, this is not a forum

Anyway, people with >3k rep. Vote to close :D

Blue

10:03

Already done.

Blue Bug

wait wtf

I can't downvote anymore? You can downvote only if you had more than 3k rep?

Kevin van der Velden

Downvote? That's 125

Vote to close != downvote =p

Blue Bug

oh nvm. This was this shitty browser thinging on this pc. I am using internet cafe in Korea nad in Korea internet explorer is still a thing. Internet explorer horrible.

Sup Pip

Pip

getting ready to head to school for the day :/

My dog hasn't left me alone for 2 seconds all morning

Sat right outside of the bathroom while I was showering

It's been wierd

Blue

Your dog's not as cool as my dog.

Kevin van der Velden

11:35

I dunno, @Pip is your dog wearing a hat?

user92578

user92578

Either with a separate brush or at the same time as the cage gets added

user92578

Level Editor sure is a lot to maintain, I'm now adding the entities to the saving and loading methods

user92578

Still this is probably one of the coolest and best decisions I've ever made

Pip

absolutely

user92578

This will require me doing a lot of cleaning up in the level class, I need to find a way to nicely reuse the level loading code from the editor

user92578

Okay saving and loading works!
