INTRODUCTION

The game was never planned to be released in public, so it's designed for the LAMP stack it was originally hosted on. Basically the code assumes some software versions and settings, and will propably break on different configuration.

REQUIRED SOFTWARE

• Apache 2.x, with enabled mod_rewrite and .htaccess files.
• PHP 5.2.x with settings like in attached php.ini file.
• MySQL 5.1, may also work on other 5.x versions.
• PHPTAL 1.2.1 - newer releases are propably also safe.
• The hosting MUST also offer crontab or other similar services.

INSTALLATION

1. Prepare database tables using attached SQL file.

2. Configure PHP using attached INI file.

3. Upload game code into server.

4. Download PHPTAL library and upload it into lib subdirectory, you should now have lib/PHPTAL.php, lib/PHPTAL/Context.php etc.

5. Enter your hosting's configuration panel and set the public subdir as a domain root, so other files won't be accessible from the Net.

6. Configure crontab: set the cron.php file to be executed every day.

7. And now the tricky part: create a config file (or files) and upload it into cfg subdirectory. It's a long and weird topic, details below.

CONFIGURATION

The game configuration is handled by the Daemon_Config class (lib/daemon/config.php file), which uses it to overwrite its public properties. Consult the class' constructor for details.

The file's content is simple, it should do nothing more than to return an associative array of settings. Here's an example of minimal config:

<?php
return array(
	'applicationUrl' => 'http://example.com/foo/bar/baz/',
	'applicationMail' => 'daemon@example.com',
	'dbHost' => 'localhost',
	'dbSchema' => 'daemon_db',
	'dbUser' => 'username',
	'dbPassword' => 'some_password',
);

The tricky part is the config's filename. As you can see in the class' constructor, it must be exactly the same as the domain on which the game is hosted, plus the .php extension. For example, if the game is hosted on example.com, then the filename is example.com.php. This is designed to prevent accidental overwrites with config for other machines...

There is also another tricky part: if you execute a script from the command line instead of URL, then the script uses a special _cron.php file instead of normal config. So you should create that file too. Or change the Daemon_Config's constructor ;)
