Mini php based one page RPG game (rp16g)

This is my submission for PHASE 2 of the Micro Game Coding Challenge.

rp16g Size:5.1 KB Planning and development time ~ 7 hours

rp16g is a small text based rougelike game based on Dragon Slayer. The player (@) must find and kill the dragon (+). The dragon is very strong for the player's initial fitness so some monster killing is needed to strengthen the player first.

Game features: - Game map; - Fog of war; - Simple battle system; - Character stats; - Romantic end Grin

The source code of the game is available here:

Small Bulls and cows in PHP

There is competition going on in bbGameZone. I decided to participate with small Bulls and cows game:

Here is my submission "CowsNBulls".

It's a game I loved playing when I was younger.

Demo: Source code: (2013 bytes)

The code can be further optimized, but let's leave something for Phase 2 Smiley Total planning + development + bug fixing time about 1 hour.

Playing with big files

If you're looking for a big text file to play with, why don't you try

Smooth tile scrolling with Slick


This is my first attempt for smooth tile scrolling in Slick. The offx/offy coordinates are not entirely correct for hero, smaller than the tile image but it's a good start the "smooth" part comes from shx/shy variables which offset the rendering position. The code is after the break:

Media Wiki Bot

I needed a bot to quickly modify the pages of So I created Mutex which kind of helps do the job. It's full of bugs with no error handling but works for me.


  require 'class.mediawiki.php';
  $mw = new mediawiki('http://yourwikiurl/api.php');
  $mw->login('botuser', 'botpassword');
  $mw->editPage('title', 'page_text');
