Representing Magick Spells - Sean Middleditch [sean.middleditch@iname.com].txt

This article describes the basics of representing and using Magick Spells in roguelikes. The general techniques are very similar to those used in my article on Object representation.

For starts, we need a class to hold the information for a specific spell.

class Spell { public:

OK. Now, let's give the spell a name.

char *Name;

There. Now, every magick spell costs Mana Points (well, if you're using a magick system similar to most others). So we need to define the spell's cost in MP.

int MPCost;

Also, every spell has a level: how difficult a spell it is. Only more powerful casters can use more powerful spells.

int Level;

There. Now all we need to know is what in Gehenna the spell does. We'll make a sub-class called Effect to store this information.

class Effect: { friend Spell;

OK, so what does a specific spell do? We'll make a simple int to describe what a specific Effect describes.

int Type;

So what does Type mean? We'll use some #define's to specify.

#define HEAL 0 #define SCORCH 1 #define TICKLE 2 #define CREATE_OBJ 3

You can of course add as many as you want. Now, we know what an Effect does, but that's not enough. For example, for a HEAL Effect, how much HP does it heal? We could base everything of level (making a rigid and uniform magick system, which may be what you want: predictability), or we could give each Effect a set of arguments to define in more detial what it does. We'll do this through the use of 5 int's.

int Args[5];

What do the fields of Args mean? That's based on what Type is equal to. For an Effect with Type HEAL, we might say that:

Args[0] is Number of Dice Args[1] is Sides per Die Args[3] is Roll Mod

So an Effect of type HEAL with Args[0] = 2, Args[1] = 6, Args[3] = 2 would heal 2d6+2 HP. Pretty simple, eh?

Anyways, we can close of the Effect class. We want each Spell to have 5 Effect's (so every spell can have lots of flexibility).

} Effects[5];

We can now close of the Spell class.

};

So that's all there is to a basic magick class.

Casting the spell is just as simple. Make a function called Cast or whatever (I used an object method inside the Spell class, since I'm a C++ OOP freak). The function would take as arguments the spell to cast, the target, etc.

void Cast ( Spell *SpellToCast, int TX, int TY );

Then we go with a big, evil, switch statement based on effect. This actually works VERY well. The flexibility is astounding...

Of course, how each spell takes effect is based on how you've programmed the rest of your roguelike. Because of the OO nature of WotR, I found it very easy to create simple object Methods for spell effects.

For the HEAL Spell Effect Type, you might to do something as simple as loop through all the Characters (NPC's and Players) in the target loc (defined by TX and TY), and heal them based on the arguments listed above... 2d6+2, or whatever.

Anyways, this is just the basics. The advanced stuff all depends on your magick system and how you programmed the rest of the game.

The complete source for the Spell class is:

1. define HEAL 0
2. define SCORCH 1
3. define TICKLE 2
4. define CREATE_OBJ 3

class Spell { public: char *Name;

int MPCost; int Level;

class Effect: { friend Spell;

int Type;

int Args[5]; } Effects[5]; };

RL Dev Code 0.6 - Kornel _ Anubis_ Kisielewicz [kisiel@fulbrightweb.org].txt

```         RL Developer Code
Version 0.6.0
Designed by Kornel \"Anubis\" Kisielewicz
(kisiel@fulbrightweb.org)
```

Hey, I noticed that both Angband and NetHack users have their own GeekCode. Why not us? ;). This is the first draft, and it\'s realy RLDev specific. I think that a Roguelike Dev Code will be especialy useful, because it may make us more aware of the others ideas. I\'m open to all new ideas, or corrections. In all project specific questions answer about your current project. A sample of the code is on the bottom of the document.

I encourage to at least post your code once, so someone can collect them and post somewhere :).

1. General info about the developers methods

\"L\": Language used to program your roguelike project.

T+++ Every minute of my spare time! T++ Most of my free time T+ Regulary T- From time to time T-- As a recreation T--- Rarely

!T I don\'t write yet!

\"R\": Rewrites. A rewrite is writing your code from scratch, using only old libraries, and fragments of the old code.

R+++ more than 5 R++ 3-4 rewrites R+ 1-2 rewrites R- not yet R-- I\'ve just started R--- I do not program yet

?R What are rewrites? !R My game doesn\'t need rewrites, cause I write error-free!

\"P\": Porting to other systems

P+++ My game will be ported to most known platforms P++ Linux and DOS/Win P+ I try to keep the code portable. P- Why the hell? I write only for Linux/DOS (you may recompile it though) P-- DOS/WIN only P--- Windows only!

!P I use Java (or something similar)

\"D\": Importance of design before programming

D+++ I had a detailed DesignDoc before I started programming D++ I had many notes and information before I started coding D+ I keep my designdoc ahead of the project, but update it regulary D- I had a few notes before I started coding D-- I had a general image of what I\'m trying to do

!D Who the hell needs a DesignDoc? I make everything on the fly! ?D What\'s a DesignDoc?

\"G\": The generic engine, that is, how generic your game will be.

G+++ You will be able to make a hard-sci-fi game out of my engine, by just changing the info-files! G++ My engine is very generic -- you will be able to make a different game by changing the info files G+ I have info files for maps, monsters, items and dungeon generators G- I have a few general info files G-- I keep everything in the code

!G Why the hell generic engine? I wan\'t to make a GAME.

\"F\": Favourite Roguelike

F:ToME F:ADoM F:V Vanilla Angband F:*band *bands in general F:Rogue Yeah :). F:Moria F:NHack NetHack F:Hack F:GH Gearhead F:DC DeadCold [more]

RL+++ A roguelike MUST be ASCII, MUST be a dungeon crawl, and MUST be based on a system similar to AD&D, and MUST be permadeath. RL++ A roguelike has to be ASCII, has to be random, and have experience levels, and permadeath. RL+ A roguelike has to be ASCII or use tiles, must have dungeons, and focus on killing things for experience. It has to be permadeath too. RL- A roguelike may have graphics but has to be rather dungeon themed permadeath game. RL-- A roguelike is a game that focuses on randomness, and features permadeath. RL--- A roguelike is a game inspired by other roguelike games.

!RL This is completely unimportant ?RL What is a roguelike actually?

\"RLA\": Roguelike community activity

RLA+++ I\'ve created a popular game, or host one of the main roguelike sites on the web. RLA++ I\'ve created a roguelike dedicated webpage (focusing not only on my game) RLA+ I\'m a FAQ maintainer, or wrote a roguelike article, or created a roguelike document RLA- I play roguelikes and post on a few roguelike newsgroups RLA-- I post on one roguelike newsgroup

!RLA Who is that guy?

2. Project specific questions

\"W\": World of the game, the genre

W:F Fantasy W:DF DarkFantasy W:AF Alternative Fantasy W:SF Science Fiction W:HSF Hard Science-Fiction W:MH Mecha W:M Modern W:CP CyberPunk W:G Generic engine (give eventual default genre in bracets)

Q+++ The plot is the master! You will have random interesting quests in my game. Q++ I will add many pre-written quests. Q+ I will add a few quest for flavor, or even ToME-like random quests. Q- Maybe a few quests for flavor Q-- Kill Sauron. Kill Morgoth. Q--- No quests -- just Hack\'n\'slash.

!Q Who the hell needs quests? ?Q What is a quest?

\"AI\": Approach to AI in your project

AI+++ AI is the key! The creatures will behave diablo inteligently and talk to you with Bot-generated messages. They will use military tactics, recognize dangers, and create traps. AI++ The NPCs will behave quite reasonable, will flee, band together, pickup and use items. AI+ The creatures will use items like wands, staves and the like. AI- The creatures will be able to pickup and equip items. AI-- No monster-inventory -- just Hack\'n\'Slash AI--- Kill player. Kill player.

\"GFX\": Approach to graphics

GFX+++ The game will be graphical with nice graphics GFX++ The hame will have tiled graphics GFX+ Some popular freeware tiles GFX- Somewhere in the future I plan to add graphics GFX-- I\'d like graphics, but I\'m a poor artist

!GFX Pure ASCII rulez!

\"SFX\": Approach to sound

SFX+++ Digitalized Speech and Music is my aim SFX++ I will add many wave files and maybe some music SFX+ Just a few Sound-Effects SFX- Maybe in the future SFX-- I\'d like sound, but I\'m a poor at that

\"Hp\": Hitpoint treatment in the roguelike

Hp+++ A 1-st level character has a few hitpoints, a 50th level character has a few hundred... Hp++ I keep the hitpoints rather lower. Hp+ The player rarely recieves hit-points, I don\'t use a level system. Hp- Fully skillbased Hp-- Fully skillbased and advancement doesn\'t make you realy powerfull

Okay. Basically, what works well as of the current version is map generation, line of sight (everything not in LOS is greyed out) and config file for key setup. The player, item and inventory structs and functions have been started. Spells, monsters and combat are just stubs.

- Map generation is by far the most complex part of this. The GenerateRoom routine (in map-internal.c) creates weird cave-looking rooms by a conceptually simple method:

```//pseudocode
while (room < target_room_size and squares_left)
pick_random_square_from_stack_and_delete_from_stack
```

(actually, I use one stack and an array of pointers to places in that stack, but the above is the underlying principle)

- config.c implements a simple parser for configuration files, that probably can be extended to other uses than key configuration.

- The Player and Creature structs have identical upper parts, so that one can use most routines for both by typecasting (Creature)player ...

- Almost everything in the game is in a linked list or contains one or more linked lists. See lists.c and lists.h .

- One of the last things I did to this source was rewriting many routines to use a "tagitems" calling convention, that is:

``` createBlah (TAG_UGLINESS, 500, TAG_MONTY_PYTHON_FACTOR, 2.1);
// (identifier, value) pairs, instead of fixed parameters that will
// change dozens of times during developement
```

- creature.c allocates the correct amount of memory for a creature, but does nothing more as of yet.

- pl_item.c and item.c is in its infancy. It has a demo item defined, and allocates it to the player, and successfully displays it in the player's inventory. Fragile. But item.h is quite well-developed, and ought to give anyone ideas...

- lists.c contains your basic single-linked lists code + the NextTagItem code.

- magic.c, help.c, combat.c, timer.c are just stubs.

- output.c / output.h / ncurses.c encapsulates most of the ncurses-specific stuff for easy porting.

- map.c ... Map_Scanfor was designed to scan for any interesting parameter inside maps, but are currently not used for much besides finding a good place for a corridor. map.c contains all routines that should be visible outside map generation. GenerateCorridor currently uses a hit-and-miss approach (copy map to temp_map -> run generatecorridor -> if grind to a halt, try again -> if not copy temp_map to map) and can be improved much, I suppose.

- types.h defines own UBYTE, BYTE, ULONG, LONG etc. types, also for easy porting.

- I'm currently undecided on what's the best approach: Defining "id" in all object structures or defining it in the "node" structure. It must be defined in any case, so we can find a specific object that we don't have a pointer to by some FindObject routine (to avoid passing a million pointers around). (started, see FindWindow in output.c)

- writing colored strings to the screen is currently accomplished by calling WriteStr as usual, with strings of the format "<White>Bob <Yellow>the Big" ... WriteStr does not do %s and such expansion, so sprintf() ing a string before passing it to WriteStr is a good thing. Look to the bottom of player.c for an example.
