Date format

Seems that I had forgotten to change the display language of this blog from Finnish to English. Fixed.

I also changed the date format to not include month name, but my preferred format(dd.mm.yyyy) can not be used if the language is English, so had to edit layout's code to pass the date to a javascript function for processing... Thanks blogger!

And then there was more collisions

Been silent as usual, but now I have SVG-based polygon map(Inkscape as preferred editor) and collision detection based on movement vectors(even high-speed objects collide to map).

Collision detection can be run in pure python(only ~120 colls/s on 108 polygon map…), or optionally accelerated with numpy(~10k colls/s) or external c++ app(~140k colls/s(that is almost 4.5M vector-vector pairs per second!) when compiled with vc++ 2010).

All values on single i7 930 thread(my new system(frostfire), with HD5850, 6GB RAM and 24” full-hd display).

My problem and how to solve it(writing, assignment, whatever)

NOTE: the following text is (mostly) grammatically correct(it was an English writing assignment at school, and why not publish it(bit late by now, thought, but anyway))

(www.)dea.fi is not attractive enough, don't you agree. Gallery2 has some minor visual defects that should be fixed, now that I officially(added a header to /pics/*) opened it. In addition, routa has some (understandable) problems with uptime. How can anyone enjoy my exquisite collection of stuff when the server is turned off? ;) On the other hand, moonforge(nor) is up ~constantly(as you would, it is a commercial service), but without much content(except that now(a?)days pics has been mirrored there).

To fix gallery2, I'm point to need some feedback on browser support(read as time, I'm sure no-one bothers to do that(not that I'm even expecting it)) and on the whole visual aspect(usability etc).

Uptime, on the other hand, is a bit more complicated to fix. You'll have to wait until I get one of those hyped Inter D510s and set it up as the main home server. Except to see an increased amount of treasures there then-and uptime, of course.

To the moonforge problem next. I myself think that the collection of shouldn't be hosted anywhere else, it just isn't so cool. Uptime(a not so great factor in the future) and at least bandwidth would increase the availability of data in case I decided to switch to moonforge. Please do comment on this dilemma.

Box2d

Been experimenting with pybox2d, not very long, but have some vids:

• Box2d python test
• Box2d python test 2
• Suspension test
• Suspension test, with engine

PS3, !mouse

PS3 shipped, and as predictable, mouse doesn't work in FPS games(apparently special, pricy, PS3 mouses work).. It works only on dashboard(and UT3).

Progressing on The Peli and introducing LCS

Polygon based map(+collisions) and editor, waypoint editor, particledemo(5k@60fps on TL-58 single thread). PHP&MySQL content management system with versioning(data only, gui is for user to build, as it should be), used in www.dea.fi(my new domain) and Lannukka. To name a few..

Not dead yet!

It has been quiet here, really quiet..

There is not much progress that could be shown to public, as I'v mostly been developing new techniques and rewriting stuff before it has even finished.

But I can tell that in tests I have easily managed to display 10k static, non-animated, objects at 60 FPS. Hundreds, or was it even 1k??, if moving.

Been also experimenting with triangle-based maps, and they seem to be a viable option. But making holes in them is bit trickier.. Of course I could have another, black layer that is drawn on top of the map and checked for collisions, but that wouldn't be efficient in the long run. Pity...

Then there is an IRC-bot, rewrote core in that once already.. But it is good, I'm telling you!

That leads to an another thingy, Lannukka. It's a going-to-be foundation/voluntary association that will someday host lanparties. Now it has mainly just been group/label/tag/... for me and few friends. Oh, yeah, the bot is on our channel, #lannukka@IRCnet.

Then theres also been all kinds of smaller scripts and stuff that programmers can't avoid doing.

Update on The Peli

The Peli is feeling just fine and has once again been re-written, this time Python(what would you except) and Pyglet(aka OpenGL). Now it is tenth or eleventh rewrite, depending on counting.

Features include

• Better particle effects
• Background varying throughout time
• Somehow nicer/uglier UI
• More speed there/less somewhere else
• Once-again seeking missiles/AI with agro
• Revamped heat/shield system, still in progress
• Minimap
• State-machine based core(easy pause menus/stuff, but)
• No multiplaying

DevNews: Quick overview at my current/past projects

It's been quiet, but I'm not dead, yet.

So I've been coding some pretty neat things, some are new(aka pys60(=for Symbian mobile phones)), and some are older(The Peli!):

• The Peli: Yeah, it's been playable someday(and it was GOOD) including multiplayer, but nowdays it is more and more a testing ground for Anyload(resource streaming system) and in lesser(O.o rly?) role in testing/developing weapon/upgrade system.
• Tankwars: Yes. Featuring weapons from The Peli.
• RPC: Worker thread/server study

PyS60:

• pyCamera: A real-time video streaming application for S60/PC. Server supports unlimited number of clients(in theory).
• devname _A[ ]memo_book: Hierarchical notes, done in need and as a testing ground for (de)flattening hierarchial data.
• Vlan_2: Network stumbler for S60.

And some that are usable but unused / deprecated / i_have_found_better_way / OS_app_exists stuff:

• Filetransfer/browser.
• chat infrastructure featuring client/server/masterserver/loginserver/encryption with can trust no-one philosophy.
• Trayer(2)

I am sure there is many more, but one can't remember everything(and that list just featured python projects, no PHP included).

E51

Yay, I have to say, seems like I'm gonna like it, as even this is written by using it.
