Dragon Knight

The Dragon Knight game engine is a web-based tribute to the NES game, Dragon Warrior.

INTRODUCTION

Firstly, I'd like to say thank you for playing my game. The Dragon Knight game engine is the result of several months of planning, coding and testing. The original idea was to create a web-based tribute to the NES game, Dragon Warrior. In its current iteration, only the underlying fighting system really resembles that game, as almost everything else in DK has been made bigger and better. But you should still recognize bits and pieces as stemming from Dragon Warrior and other RPGs of old.

This is the first game I've ever written, and it has definitely been a positive experience. It got difficult at times, admittedly, but it was still a lot of fun to write, and even more fun to play. And I hope to use this experience so that if I ever want to create another game it will be even better than this one.

Once again, thanks for playing!

CHANGED FILES:

• install.php (do not upload if you've already installed the game)
• lib.php
• fight.php
• help.php
• config.php NEW FILES:
• upgrade_to_112.php DIRECTIONS: If you're already using 1.1, upload the files above (except for install.php). Be sure to put your database values into the new config.php file. Then run upgrade_to_112.php in your browser. If you're still using a 1.0.x version, you should first perform the directions for upgrading to 1.1.0, then 1.1.1, in that order. Then upload the files, then run the upgrade_to_112.php in your browser. NOTE: Running the upgrade script should only be done if you did not alter the order in which new spells are gained. Changes to the actual spells don't matter, only the levels in which they are learned. The upgrade script will automatically reset spells for all user accounts to their default order. If you have altered that order, just execute the following two SQL queries in your admin program of choice. ALTER TABLE dk_users CHANGE towns towns VARCHAR( 50 ) DEFAULT '0' NOT NULL; ALTER TABLE dk_users CHANGE spells spells VARCHAR( 50 ) DEFAULT '0' NOT NULL; Be sure to substitude "dk_users" to your actual table names, if you've changed the prefix.

1.1.1

CHANGED FILES:

• users.php
• towns.php DIRECTIONS: If you're already using 1.1, you only need to upload the two files listed above. If you are still at a 1.0.x version, you need to do the 1.1.0 stuff listed below as well.

To upgrade, upload the above-listed changed/new files to their proper directories. Re-edit the proper variables in config.php. Then run upgrade_to_110.php in your browser. After the upgrade script has completed, log into the game and reset your Main Settings in the control panel.

1.0.4

CHANGED FILES:

• config.php
• fight.php
• index.php

• help.php
• help_items.php
• help_levels.php

Upload the changed and new files listed above, delete the extra copy of install.php from your /admin/ directory, then delete the entire /help/ folder altogether. All help files have been renamed and moved to the main directory, to get rid of the paths problem that was occurring. Make sure you re-edit the appropriate variables in config.php too. Note that the $app_path variable in lib.php is no longer necessary, so it has been removed. config.php is the ONLY file you need to edit to make the program work.

• fight.php
• lib.php
• install.php DIRECTIONS: No database change is necessary. Just upload the files listed above (do not upload install.php if you already installed the game without any problems) and re-edit the appropriate variables in config.php. There is a new variable at the top of lib.php that you'll need to edit as well.
