[JS] Castle Wolfenstein - an homage to Wolfenstein 3D in 20 lines of JavaScript

[p01]

It's a little quiet here. Let's post something.

Other there at the Ozone Asylum we have some 20 lines contests in JavaScript. It's a really fun exercise. The topic last month was about dynamics. I made some kind of hypnolgow ( always loved hypnoglow ) but the most interesting piece I delivered and am polishing now, though still in 20 lines is:


Castle Wolfenstein - an homage to Wolfenstein 3D in 20 lines of JavaScript


_{Before you ask : it doesn't work in IE. Works great in Opera 9.5 ( sorry don't have 9.2 at home ), and I'm investigating why FF3 chokes on it.}

It still supprises me that js can do this kinds of thing.

I really like hypnoglow its cool, and you done a pretty good job at wolfenstein

Isnt FF3 in beta atm? or did I miss something

[p01]

Thanks.

Yes Opera 9.5 and FireFox 3 are still in beta. FF3b2 came out ~6 weeks ago, Opera 9.5 build 9721 one month ago.

Kewl. Excellent work.

Never head about the <canvas> tag though ... nice! New
stuff to study 8-)

Wolfenstein in 20 lines of Javascript?!?!
crumbs!

I just downloaded and installed Opera just to see this in action and I must say that I am dumb-struck. This is very impressive for 20 lines of code. Very well done p01. Anyone else that hasnt seen this because they are using IE do yourself a favour and install Opera.

[p01]

that's a cool way to discover Opera.

Btw, there's a few new features since my first post:

• exit door
• generation of a new level : reset the player's coordinates and health and display an alert( "ENTER ROOM "+ M.level )
• create an increasing number of attack dogs per level
• fixed the markup generated. Very slight speed increase in FF3b2, but Opera 9.5 remains ~2x faster, with Safari 3b4 in between

The script is now 19 lines ( excluding the logs, to try and understand why FF3b2 is so slow ). I believe I can fit the player's game logic and a basic HUD in 20 lines.

I would not have said it was possible to squeeze Wolfenstein into so few lines of code.
We had a 20 line competition here some time ago, and some of the code was pretty obfurscated, nobody made a raycaster though!

There were some interesting things made however.. I think Optimus won that challenge with a lense mapped Xor thing

Very very cool, hypnoglow effect rocks

P01 - that wolfenstein is awesome. Very very good programming.

[p01]

Thanks. It's cool to such feedback, esp. from some crazy optimizers.

Impressive, both in size and how you mastered the engine. I'm very fan of this.
Keep on this pure work, it's always a pleasure to run your creations.
