Isn't that sexy? Everything character-related processes well. Item descriptions are available in tooltips when you hover your mouse over them.

Status Report: ReXML

So far, I have successfully created a system that uses XML pseudofiles (which I will explain and document in a later post) to store data in a database, and the code to read the XML data and turn it into something meaningful for PHP is finished. Tonight, I work on the system that turns everything back into XML data and updates the database. I'm using a system of flags in an array called $REXML to assist in this process. It should be fun to program.

One of the biggest obstacles in picking this project back up is remembering the syntax. For example, dungeon data is stored in $GCHAR["d_data"]. Player data is $GCHAR["d_data"]->player, and the player's current HP is stored in $GCHAR["d_data"]->player->hp. Remembering the differences between arrays and SimpleXML objects is a bit of a pain.

Incidentally, one of my characters has a $GCHAR["d_data"] that looks like this:
<?xml version="1.0"?>
<ddata>
<player>
<hp>7</hp>
<sp>12</sp>
<encounter>0</encounter>
<initiative>0</initiative>
<x>0</x>
<y>0</y>
<dungeon>0</dungeon>
</player>
</ddata>

While another's looks like this:

<hp>17</hp>

<encounter>0</encounter>

Things can get messy, but everything you see should be auto-generated by the server.

An overview of the accomplished

Okay, time to talk gameplay! What will AO offer that other text-based online RPGs won't? Here I will discuss two very distinct things: Ideas that have been implemented and ideas that WILL be implemented (unless someone gives me a really good reason to reconsider them). Let's begin with the former.

Implemented
Character Creation
Being that the game is heavily influenced by Dungeons and Dragons, the character creation process was the first thing I finished. To begin with, you select your character's race. At first, you only have access to six: Humans, Elves, Dwarves, Halflings, Tieflings, and the Eldarin (High Elves). However, as you play the game, you will encounter new worlds and, through questing, unlock the ability to play as new races.

Each race has its own strengths and weaknesses, although none of the latter are gameplay hindering. For example, Humans gain levels 1.5% faster than most races, while some sidequests are only available to Tieflings. Most of the unlockable races will be able to play through race-exclusive quests as they level up, to enhance replay value.

After you pick your race, a plethora of classes will be available. Multiclassing is allowed, and encouraged, with no penalty. However, spreading yourself too thin might prove to be problematic, especially if you desire the opportunity to play a prestige class. There will also be unlockable classes, such as Paladin and Blackguard.

Then, the server rolls 6 stats and you get to assign the values to STR, CON, DEX, INT, WIS, or CHA. If you don't like what you see, simply reroll until you're satisfied. Note that it's unlikely that you will get all 18s. This process is entirely server-side, so there's no chance of manipulating the results or creating a level 1 character with 200 STR or -64 CHA.

The next process in the character creation process is to select your feats. Some classes grant bonus feats at certain levels; others provide them automatically. Skills are learned from NPCs and automatically from leveling up (especially when you level Prestige Classes).

Ideas Yet to be Implemented


Cohorts

Suddenly 20 Ghouls swarm around you. Oh no! Luckily, you have 5 bodyguards with silver-coated weapons to help you dispatch them all.

Some NPCs will aid you in your questing. Some are useless VIPs whom you cannot let die, others are epic warriors who cut down hordes of enemies. Some will only accompany you for one battle, others will follow you beyond the ends of the earth until their dying breath. Some are summoned creatures and your familiar (if you're a spellcaster). The possibilities are endless. (Note: Most will want to stay in the level they joined.)

AJAX Arena

What's the fun in leveling up an awesome character if you can't kill your friends? Well, you can. Or at least, you will be able to when the AJAX-based Arena is completed!

The Arena will consist of a chatroom and a battle system in one. Private rooms will be allowed for RPing, but all fighting will take place on the Battlegrounds. That is, of course, unless the private room is opened by a GM for a special event. GMs-- either during special events or for general RPing in the Battlegrounds (main lobby)-- will also have the ability to grant experience points and conjure items into your inventory.

Okay, my writing is becoming less coherent, so I should end it here.

Scripts, subscripts, and subsubscripts!

It's amazing what a short snippet of well-written code can do to make your life easier. For example, take my gfmodulec() function:


function gfmodulec($sdata)
{
global $GCHAR, $GDATA, $charlook, $GSWITCH, $GVAR, $COMBAT, $COMBATORDER, $NUMBER_OF_FLAGS, $NUMBER_OF_ENEMIES, $U, $PLAYABLE, $COOK, $VISIBLE, $SELECTABLE, $socache;
// Create a random file for inclusion and deletion; return its name.
$randomfilename = GAME_ROOT."/temp/".kcenc(microtime()."a".rand(1,10000)).".inc.php";
$fp = fopen($randomfilename, "w");
fwrite($fp, $sdata);
fclose($fp);
include($randomfilename);
unlink($randomfilename);
}

That might look intimidating at first, but it's actually quite simple. First, the "global" statement tells it to import a bunch of crap. All of those are either arrays or SimpleXML objects. Don't worry about them too much.

The $randomfilename is exactly what it sounds like. kcenc() is Kobra's Custom Encryption function, but the final output is an md5() hash, so it doesn't look too strange.

The rest is easy as pie. It creates a file with the data ($sdata) passed to the function, runs that file, then deletes it.

"What's the point in all this?" It's simple. By using data stored in MySQL, I can write weapons, spells, etc. that can do literally ANYTHING! A sword that randomly (1/10,000 chance) replaces your enemy with a level 1 slime but doesn't reduce its EXP or item gains? No problem. I throw some PHP into the SQL value for that weapon's "script" and viola, an interesting relic!

This means I can make abilities that only work in certain worlds, or on certain types of enemies, too. In fact, every skill, spell, feat, or attack (to the engine, though, there are just skills and feats) will be an include()d PHP script.

It's probably not the most optimal way to do things, but it sure as hell makes things interesting.

Inaugural Blog Post

Let's cut right to the chase, shall we?

I am Kobra, the author of Kobra's Corner, and this is a developer's blog for a MMORPG I'm, well, developing. I have given the project the name "Anachrony Online," although that is likely to change as I come closer to finishing the game.

In the coming hours, or more likely, days, I will be posting some basic information about the game, some ideas I wish to implement, etc. in hopes of getting some feedback from the community.

But first, I would like to outline some goals I have yet to meet; mostly for my own convenience rather than for onlooker curiosity:

1. Finish the registration system.
   
2. Finish the "level up" system.
   
3. Start and finish the Dungeon's battle system.
   
4. Start and finish the Dungeon!
   
   
   
   • Switches, variables, etc.
     
   • Subscripts and subsubscripts.
     
   • Choicesets.
     
   
   
5. Start the AJAX-based Arena.
   
6. Finish the AJAX-based Arena.
   
7. Make the first dungeon.
   
8. Alpha testing!
   
9. Tweaking.
   
10. Complete the inaugural dungeons.
    
11. Beta testing!
    
12. More tweaking!
    
13. Public release.
    

That is how it looks, currently.
