Code Combat: Open Source Javascript Tutorial Gamification (In A Good Way)

youtube.com/watch?v=dCOHjERswGw

Code Combat is a javascript programming learning IDE wrapped in a delicious cute RPG/2D RTS packaging that runs in the browser without any plugins. They recently announced their open source/free art release.

The current set of Code Combat tutorials starts with directional movement and activation of pre-programmed behavior, continues with coordinate movement and targeting and conditional behavior and continues towards prediction calculations.

Editor GUI

There is an editor, officially described as "broken". I can confirm that the text editor was slow when I tried using it. :)

All in all, a very exciting project. I have noticed a few possible drawbacks so far:

• It's not yet clear which parts will not remain proprietary. It looks like the excellent humor (writing) unfortunately will do so (legal page).
• The music tends to be too exciting to code to.
• There's a CLA requirement for contributing.

What do you think? Persuaded to work on a HTML5 game yourself perhaps, seeing that this performs okay? :)

Dev-corner: JUICE up your game

I just happened to come across this nice presentation, and I guess a lot of FOSS games could also take this as a valuable advise:

Juice it or lose it

The "game" they are presenting is playable in your browser by the way, try it here (hit esc for the menu).
Oh and believe it or not, source-code is available too ;)

So don't forget to JUICE it real good!

Cube Train, Frogatto development and LPC

Today is another session of: "Look what I found in my FG spam folder" ;) But this time I am actually adding a lot of nice other stuff to it, so that it is almost a "dev-corner" post!

But first things first... the frogatto developers made us aware that there is a new game based on their really nice 2D engine, called Cube Trains:

Cube Trains Beta gameplay

Note that, just like frogatto, the final version will cost a few pennies, but the engine is totally FOSS and the current Beta is still free to download.

This seems to fit to the general idea of the folks behind this engine as they outlined in the email to us:

I'm really glad we now have a second major title done in frogatto's engine, because we're gradually trying to position frogatto's engine as an open-source alternative to closed-source packages like GameMaker or RPGMaker;  partly just because development tools are one software category that benefits far more than other categories from being open-source, but also because our engine technology is a lot better than GameMaker;  we're fully GPU-accelerated, and we've got a much better internal programming language.  We've got a ways to go, since GameMaker still has a bunch of advantages over us on the gui side, but we're getting there.

Cube Trains is not one of them, but eventually, we're hoping to build a stable of "starter kits" for different game types - like GameMaker has, built under a CC0 license so they're suitable not just for GPL games, but for absolutely anything (indie titles being a big one).  Hopefully that was we can get a bunch of people from the indie gaming crowd behind an open-source tool.

Which seems like a pretty good idea to me, and looking at the awesome features they recently showcased in three tutorials (1,2,3) I wholeheartedly agree with the comment on their superior engine technology!

Speaking of the frogatto engine and tutorials I can elegantly lead to my other topic today, as the people behind the currently pre-warming Liberated Pixels Cup, aka our friends from OpenGameArt, are also endorsing the use of that engine as outlined here. The have also recently featured another really nice 2D game dev. tile editor, and hot of the press is the news that the Mozilla foundation has joined the FSF and Creative Commons as a main sponsor of the event!
With Mozilla also came a significant cash contribution, which means that the initial goal of US$ 10,000 has been reached, but you can still up the ante!

It seems that this comes along a general push from the Mozilla Foundation towards more HTML5 gaming (now part of the LPC too), supported by the fact that they have recently released a nice RPG game demo (BrowserQuest) and are working even on a 3D engine called Gladius.

Ah and not to forget: OGA has also recently added a nice featured tutorial section to their site... so nothing is holding you back to finally become an active part of the FOSS game-development community... yes, I said YOU! :D

Blender Game Competition 2010

Dear diary...ermm readers *hust*... this is my first post on this blog so please be gentle with me! I am sort of helping out now and then since qudobup is busy with other stuff. Beeing a forum regular I had to help out of course, even if I might not have the time to post that often.

Ok now to the really important stuff: Blender (everyones favorite GPL 3D modeling application) also has a build in game engine. And what would be nicer than having a nice competition for game creation?

Here is a video of one of the winners from last year (not open-source!):

So why not join in that get a chunk of the $500 prize?

Why Blender game engine (BGE)?

Wasn't the game engine always the stepchild of the project? Slow, bloated and buggy?
Well things change, and with this years open game project Yo Frankie! things have taken a leap towards greatness!
Speed has been greatly improved, physics are completely integrated and you can do great eyecandy with the OpenGL 2.0 GLSL shaders (here are some more features).
And things look even better with the upcoming Blender 2.5.

Getting started with the BGE

So what can the BGE actually do for aspiring FOSS game developers? Well it is a "game-maker" for grown-ups... so if you want to make games and not learn how to become the the next John Carmack (tm) the BGE is for you. On a low level you need no programming at all, much can be done with the "logic blocks". And for more ambitious projects the BGE is fully scriptable with Python (which is one of the easiest and most comfortable programming languages).

And did I mention that games created are completely multi platform? Linux and MacOSX ports are just one click away!
A good first step would be to head over to blenderartists.com and surf a bit on their game engine sub-forums. There you will find free (some GPL or PD even if the license is not always 100% clear) templates (f.e. FPS or network) and many great tutorials.

And most people there will freely share their .blend files with you which include all art assets, scripts and so on in neat package (open them in Blender, press "p" and the game starts). However not all of it is really licensed in a FOSS way, but at least you can use these as great tutorials. Overall one could say that this is a great way of distributing the "source" of complete FOSS games (code, art, music etc).

Other sites worth noting are GameBlender and maybe the new Blender Games. And of course for all your Blender news: Blender Nation!

So my excuses for these more game development related news... but you will find some nice games to play (done in Blender) in the many links I provided :p
But next time there will be more traditional gaming news!

Update: Some seriously nice eye candy!

This was just released and looks really nice!

Head over to the Blenderartists thread for more info (and .blend download!).
Oh and yes you are free to use it in your own projects!
