OK, how about an "official" compo? Someone should put up a website with the rules, and some way (e-mail or upload) to submit entries...

Well, I have a lot of things to do (I'm so lazy::)) but if nobody else wants, I can do a 'ScreenHack site'.

It won't be a compo as SpeedHack or TINS or BlithzHack, but it will be a site with lots of multi-platform games that fits in a 25x80 characters screen.

I'll get the better games from this thread and put him in to the site with links to the websites and mails of the authors and compile them in zip files. And I'll put an e-mail so anybody can send me his creations.

[edit]Uh... 'ScreenHack' wouldn't be a cool name for this site, since it will not be a compo.

• ScreenHack

• Screen-games

• MicroGames

• AlleScreen

• Micro-screen Games

• ...

Most of them has a lot of Google/Yahoo/Lycos/Terra entries...
Any other sugestion?
Please?
[/edit]

Well, I was wondering that somebody would confuse the names:

ScreenHack-SpeedHack...

Ok, ok, forget it. The name will be ScreenHack.

I'll start just now.

It ain't java, ya know.

Try ("%i",score).

Here you have: The ScreenHack web site.

I know it isn't the best web ever, but it's late (19:49pm at local time) and I'm tired. I'll try to do something better this week-end.

note: I've called the site ScreenHack2004 because somebody has a Yahoo! ID named ScreenHack but no web...

/me wipes sweat off forehead.
My submission (80_25_Chase) compiled successfully on linux(Gentoo, gcc 3.2.3). I've attached the resulting binary program. I wasn't able to fully test the program, however. My linux machine can't run any AGL apps yet, and it's also flaky on some Allegro apps, but oh well. I hope this binary works.

BTW, when I ran it, I got a segmentation fault. I discovered that the problem was that, set_gfx_mode was failing(obviously, since I mentioned the machine can't run AGL apps) and the next allegro calls or something caused a crash(segfault). So if you get a seg-fault, it's only because there's no error checking on set_gfx_mode

Long Live Linux! Power to Cross-Comptability!

OK, here`s a little question about the rules:

Can I use values instead of some Allegro defines like 0 for GFX_AUTODETECT?

Krzysztof Kluczek: I'm pretty sure you can...cause I did! heh. does GFX_AUTODETECT resolve to a constant number? I know that GFX_OPENGL_WINDOWED doesn't, it's platform specific. I resolved all my KEY_* though.

I guess it`s rather platform independent.

As for the KEY_* constants I was quite surprised when moving form Allegro 3.* to 4.* since their values changed! In previous versions they were equal to raw keyboard scancodes and now they are more logically assigned (eg. KEY_A was 30, now it is 1, KEY_B is 2 and so on... ).

Anyway I`ll wait for Goodbytes opinion.

edit: I got this opinion when was writing this post.

Nice game.

I had to change two things before I got it running under DJGPP:

1. Change graphics mode and backbuffer size. In DOS there is no windowed mode and you have to use screen resolutions (I changed to 640x480).
2. I had to add vsync() before blit() since it was really too fast (I think 0.1s was enough to travel through entire screen).

(consider changing it in your source to make it portable)

OK, I`ll return to play.

edit: I found there is way to cheat - just hold control key pressed and everything that touches you gets killed. Consider making player bigger/the bomb smaller or swapping collision checking order.

Oh, and rest() requires install_timer to work properly.

okay, i fixed some stuff, made it (hopefully) cross compatible, and added a lifetime to the mine. Tell me what u think

edit: hold 1/2/3 when its loading to slow it down if its too fast.

edit2:
I was thinking that this game probably makes no sense::), so ima explain it a little. The object is to destroy all the bad circles by dropping your mine in their path(Right Control). But dont let them touch you either, cause then u gotta start all over. After a certain amount of time, the mine expires and you have reset it. Also, leaving the ring automaticaly starts you over. there are 9 levels to beat. and...well, I hope that its fun. Its my kind of game anyway, the kind that is near impossible to beat but you try for hours and hours:P

if the game runs too fast, press and hold 1, 2, or 3 while the game loades (3 being the slowest). the default is 0.

attached is a linux binary

Move the mouse to avoid the swarm of killer dots that are gravitationally attracted to you. Your circle becomes redder the closer you are to death. Press ESC to quit prematurely.

I'm most impressed by Krzysztof's game - there were a few compiling issues (djgpp) and editing it messed the map up a bit. Eventually I had to use two diferent version of the code, one for the map. I'll be trying some of the recent ones now...
