## WHAT IS IT?

Simplified model of original (1974) D&D combat.

## HOW IT WORKS

Men vs monsters. Each combatant targets the closest enemy, and closes in at his max mv until they are in melee range. The attacker attempts to hit his target (using the tables in the 3LBBs, volume I), until attacker or defender dies. If defender dies, attacker picks next closest enemy, if any, and repeats process.


## HOW TO USE IT

Use controls to choose number of Fighting Men, their Level, AC and MV.

Use controls to choose up to two kinds of monsters and their numbers.

Click the setup button, and they are arrayed on the battlefield. See the screenshot on my Flickr photostream here http://www.flickr.com/photos/79364035@N04/8645207600/

Click the Go button and they fight until one side is destroyed. Screenshot here http://www.flickr.com/photos/79364035@N04/8645207760/

A plot shows the number of survivors at each tick.

## THINGS TO NOTICE

Ghouls paralyze victims. Man bitten by Ghoul must save vs Paralysis or he's disabled for 2d4 rounds.

Ogres do extra damage (d6+2).

## THINGS TO TRY

If men are disadvantaged, try increasing their level, ac, or number until balance is restored.

## EXTENDING THE MODEL

Top 10 TODOs:

(1) Adding a d6 roll for a surprise round. And 25% chance to drop weapon if surprised.
(2) Using agent's "heading" property and x/y coordinates to determine if a defender is flanked or attacked from the rear, in which case bonuses apply.
(3) Add more monsters. Right now the model only supports 4-- Orcs, Hobgoblins, Ogres and Ghouls.
(4) 1st level Fighting Man gets +1 to-hit bonus against "normals", and Nth level FM (N>1) gets N attacks against normals.
(5) Add Cleric, Magic User, Elf, Dwarf and Hobbit.
(6) Exploit NetLogo's 2D patches to code terrain (hill, wooded, marshy, ditch, river), structures (walls, towers), and so on.
(7) Read battlefield setup (including troop types/locations/terrain) from file.
(8) Allow for houserules.
(9) Allow for combat engines other than the OD&D alternative combat system (ACS), incl. Chainmail 1:20, Chainmail man-to-man, Chainmail fantasy supplement, Greyhawk weapon type vs armor class, etc.
(10) Get the "export as" Java applet and QuickTime movie to work.


## NETLOGO FEATURES

Makes use of higher-order functions (task/run).

## RELATED MODELS

I wrote a simulation of OD&D combat in Perl. It supports surprise, drop weapon, more monsters. But It's just a 1-man to 1-monster slugfest. Not 2D. No graphics. No movement. It runs a given simulation many, many times and reports a number of statistics. The code is available in my pastebin at
