@thedaian, that was quick

i am quick

like ninja

No kidding

also i've seen the steampunk portal device pictures. it's awesome, and yes, I do want one.

(fyi, I'm referring to a very recent G+ post I made about this: batman-n-bananas.deviantart.com/art/…)

I mean, who doesn't, right?

Indeed.

Candidate for the longest answer? gamedev.stackexchange.com/questions/26080/…

6:28 AM

A good candidate too. :P

I just installed Ubuntu.

(in a VM)

It's very fancy.

I had forgotten how much I dislike gnome-terminal.

Chorche

9:30 AM

Hi all

I started learning c++

Trevor Powell

howdy

Chorche

can anyone drop a link to a good tutorial using openGL in c++

:D

some really simple tutorial

a triangle tutorial

i don't even know what kind of project should i create in codeblocks, if i want to develope a game

Console project?

1:09 PM

@Chorche they say this tutorial is good:

arcsynthesis.org/gltut/index.html

but I didn't try that myself.

3:08 PM

When would I use linear algebra?

3:51 PM

Hey, only 15 more votes and I can unlock the unclaimed Reversal badge ;p

4:15 PM

what? unclaimed reversal?

this room is pretty empty

This is actually pretty busy for a weekend

As for when you'd use linear algebra: I have only really done 2D programming, but things like cross and dot products are useful, as well as matrix transformations

4:33 PM

well math makes me run so I have to do

well some math

ic

yeah, you can get by in 2D programming without linear algebra (I did for years), but there is no avoiding it with 3D programming

I knew linear algebra, but I never applied it in my games until recently

WHERE can I learn linear algebra? (I want to move to 3D eventually)

I went to university for Computer Science, and it was a required 1st year class

I didn't move on to take Linear 2 or 3 or 4

well, I mean something like a site or a book (if a book is the only way)

yeah... I'm not the person to ask, although I'm sure someone else will have an answer for you

4:42 PM

wait, what about this: blog.wolfire.com/2009/07/…

that looks pretty brief, but it looks like a good place to start

There's 4 parts to that

It's reasonable

Well... there are parts: 2, 3, and 4

yup

yeah I guess so. I was learning about sin, cos, tan, atan, atan2, etc at a different place but it had problems and I had trouble understanding it.

I guess I never really thought about vectors being bundled in with Linear Algebra, but thinking of it now, of course they are

4:47 PM

Sounds like you want trig too

So yeah, linear algebra is almost unavoidable in 2D as well as 3D

It sure makes things easier

well I guess I will have to read that then.

If you're just getting started with gamedev, I'd highly recommend starting 2D

Agreed

4:49 PM

I already made a simple game

2d

3D is significantly harder and requires a lot more math

I don't even know where to begin with 3D actually, or when someone should begin

What about you @Byte56?

That extra dimension sure does add a lot more than just one dimension

Where to begin?

I almost forgot, do I use sin or cos for the z?

the page I read was only for 2d

which was one of it's problems

Depends what you're trying to do

@JohnMcDonald You mean where to being? Or when?

For calculating it's next position

4:53 PM

@Byte56 Both

I've never actually touched 3D games before

oh dear

Well I didn't do it the "right" way, so it's hard to say. If there even is a right way

and I've been programming games for well over 10 years as a hobby

I did a few 2D games, then went full on into a very large 3D project with my current project

and I've been interested since I was about 5 but I had no clue how they were made

4:55 PM

hah, you reminded me, I did actually try to make a mod for Half-Life. So I guess that's 3D

That counts

Then I went right back to 2D

I've modded for mc (sorta) before.

I think I'll be doing 3D for my next game

Someday when I finish my current

Long from now probably :)

:p yeah

4:57 PM

Er I mean 2D for my next game

Oh, ok

As for starting in 3D... I guess modding or adding onto existing code would be good

Use an engine for sure

Oh yeah

I finished my 2d fighting game in about a total of one day but it was very simple. seeing as you both have experience, how long does the average game take (I know that can't really be answered but I mean on average)

Don't do it the way I did. From scratch making your own engine :/

Well, I've been working on mine in my spare time for nearly a year now :)

Had I used an engine or existing code I would have been a lot further along

5:00 PM

spare time, I have plenty of that.

hah, I've been working on mine (hobby project only) with a good bit of social life thrown in, for almost 3 years now

So... it really depends on the scope of the game you pick

That's the pace for non-full time type games

You always think that your ideas are simple, always. But guess what? They're not, think simpler

well, how much time if you were working solid. what would the total time have been so far

Maybe 2-4 months of 40 hours a week

But, I write something, then find a different way to do it, backtrack and so on

It's my first large scale game after all

So there's plenty of learning

5:04 PM

how would you say it took for v0.1 or the first playable version took?

Can't say. I'm not there yet :/

I've been building the engine longer than the game

one sec

so if you start with an engine you'll be much better off.

It's been so long, it's tough to say how many hours I've put in. I have 23k lines of code that I wrote for this project, @thedaian has something like 15k for IsoTower, others have somewhere in the range of 18-30k. Maybe that helps judge?

Ah, I'll count mine...

Eclipse have a built in for that, or do I need a plugin?

5:06 PM

is that including lines that just have } on it?

My very first playable game did only take me 2 weeks for the first version, an other month for the second version, and an other month or two for the third. And by then, the code was a horrible horrible train wreck that I abandoned the project altogether.

That includes everything:
Comment Lines: 4138 (18%)
Blank Lines: 3896 (17%)
Code Lines: 14994 (65%)
Code w/ Comment: 109 (0%)
Total Files: 171
Total Lines: 23028

but it was experience.

Yup, it was a fun experience, and not a single one of my projects since then has been nearly as small

Also, those numbers (I think) include all testing code

umm...is that built in? in eclipse where do you go to do that?

a mandatory part of the project

I use C#, and I wrote a line counter a long while back

5:10 PM

oh

I'm looking around, I'll let you know about elcipse

what? it says my OWN post was probably not read. it put that line above it.

yeah... don't trust the line

Damir

@AidanMueller stackoverflow.com/questions/1043666/…

so it's not built in

ok

hey what happens I delete system3..........

5:12 PM

Ah nice, thanks

Total lines is 25.3k

wow

how long does it take to write 1000 about?

That's pretty hard to say

oh

It depends on what you're writing and how clever you're being :)

From my personal experience, you'd be hard-pressed to get above 10-15k without having written a few smaller projects first

5:20 PM

so it mainly is on wpm and what your writing?

what if I'm on a dvorak

It doesn't really boil down to that. It wouldn't make sense to think of it like that

Your wpm doesn't factor in

imo

I don't usually write code as fast as I can type.

Programming is all about thinking

I wish I could, but I don't think that fast

5:22 PM

I've noticed that too. but i'm a slow typer <----not a word

typist?

Someone more experienced than me, or me now, could have written my current code base in considerably less time and likely smaller/cleaner

yeah I know but I dind't feel like it

if only typer was a word

So you on spring break now Aidan?

nope

saturday

5:24 PM

I mean next week is no school right?

umm...spring break is over

Oh, ok

It's just starting for kids around here

Oregon

you in canada?

oh

oregon

I was going to say, pick something you think you might be able to do in a week

what about a day

or two

or seven

5:26 PM

Yep

:D

Then add on to it

Holy crap, someone is actually planning to make a small game!

well I could fix the code for my fighting game

That's a good start

5:27 PM

@JohnMcDonald not planning, already did

Well, sounded like you were thinking of making an other in a day, or two days, or seven

My first real game was a clone of Combat

Just the air portion

And at the time, I couldn't remember what the game was called, so the project will forever be know as "That Atari Game"

@john do you know how I can get access to steamworks API to create an indie game?

Umm... you talking about getting a license from Valve to sell an indie game?

nope

Or are you talking about making a free mod based on the source engine?

5:36 PM

I'm talking about their client/server communication library.

plus usage of their servers.

for a non-source game. Ok.

yep

actually it doesn't matter if it's source or not.

umm. my understanding is that they don't provide that information until you're almost ready to implement that

I only need a code to get a dynamically created object and render it!

You've seen this, right: steampowered.com/steamworks/gettingstarted.php

or here: partner.steamgames.com

Cool

5:41 PM

FF froze

Actually, I didn't think they provided this much detail until you were basically ready to ship

:/ yeah... you get the front page overview without having a mostly complete game to demo

it's silent

in here

it's the weekend

We've been silent for like 20 hours one time

oh

@JohnMcDonald yep, already saw those.

5:51 PM

:/ yeah

but the game I'm trying to create is heavily based on multiplayer feature.

Multiplayer is done yourself. Valve doesn't have a hand in that, other than maybe the matchmaking

so without being able to compete against another player it just looses it's whole gameplay.

I can hook you up with my matchmaking service if you'd like?

that's not the point

5:53 PM

Or just use IPs for now

If you look, they don't provide multiplayer code for you: steampowered.com/steamworks/gameservices.php

I'm also looking for a dedicated server.

They don't do that. You do

A dedicated server is basically just an exe that only runs the server (no graphics output)

if they do the match making and also all the server/client communications, I need nothing else

They don't do the client/server communications

sfml?

you could use that

5:55 PM

@JohnMcDonald they have to, then what is steam doing in there?

found the link,

I've never used it but it works with c++ D Python .NET C

they do peer to peer networking

partner.steamgames.com/documentation/api

they also do so many other things

That's just a fancy way to say that they can set up matches

Peer to Peer is no different than Client-Server, except where both people are Clients

clients can act as servers.

You're still responsible for sending all of the data over the wire

5:58 PM

no problem. I'm just looking for something to deliver them fast and reliable!
