Active Worlds Bots


is an avatar that inhabits a virtual
world, interacts with other avatars, and is controlled
by a computer program instead of a human being.

Active Worlds Implementation:
the AW Software
Development Kit (SDK) provides a programming
interface to the AW server. There are some programs
already implemented that create a bot in AW, and
allow you to customise the bot by editing a script that
determines the bot’s behaviour.

Active Worlds Bots Examples

The bots that we will be using provide lower level
intelligence by performing
fixed responsive actions

Types of bots already implemented:

Conversational bots:

HamBot, ChatBot, Preston,

Automated music bots:
HamBot, XelagotBot.

Object building bots
: HamBot, BuildBot.

Simulation bots
: BirdBot, BallBot.

Games bots:

Administration bots:
PhoneBot, VoteBot, BuildBot,

Introduction to HamBot

HamBot: a general purpose bots creation and
manipulation program.

HamBot: runs simultaneously with the Active Worlds

Share same station with Active Worlds browser.

Share same Internet connection.

How does HamBot work?

Each bot associates with a citizen who has right to own bots.

Maximum 3 bots per citizen in Active Worlds.

HamBot can then run independently even without the
presence of the citizen it associates with.

Usage of HamBot

To simulate Active Worlds citizens.

Appear as an avatar.

Navigate in Active Worlds.

Chat to other citizens via the control of a script or a person.

To serve as a tour guide.

Respond to pre
set keywords.

Play background music.

To serve as an assistant.

Build and manage object properties.

Other interactions with the environment and citizens.

Configuration of HamBot

Configuration file: HamBot.ini

Citizen information.

Configuration of Script Files

Script files: contain scripts that function a bot.

Syntax of scripting language:

StartBot (start a bot in Active Worlds).

Avatar (define the appearance of the bot).

Movement (define the movement of the bot).

IfTextContains (catch keywords).

Say (provide response for a certain keyword).

DoBuild (build objects in Active Worlds).

Syntax of Scripting Language

StartBot (start a bot in Active Worlds).

Set B$=ChatBot (name of the bot).

Set W$=vds (name of the world where the bot will enter).

StartBot=0/%B$//%W$ (0 indicates this is the first bot).

Avatar (define the appearance of the bot).

Set A=3

Avatar=A (the bot appear as avatar three).

Syntax of Scripting Language

Movement (define the movement of the bot).

Movement=0 (the bot can not move in Active Worlds).

Movement=1 (the bot move in Active Worlds).

IfTextContains (catch keywords).

IfTextContains=ShowHelp Help (if text contains “Help”, then
it can be used as label “ShowHelp”)

Say (provide response for a certain keyword).


Say Ask me about Virtual Architecture, time and HamBot.

(if label is “ShowHelp”, then send text “Ask me about Virtual
Architecture, time and HamBot.” to Active Worlds)

Syntax of Scripting Language

DoBuild (build objects in Active Worlds).

Set B$=create sound house2.mid

Set A$=flower4.rwx

DoBuild A$ B$

(build an object in Active Worlds with model name “flower4.rwx”
and action “create sound house2.mid”)


BotChatExample.txt: a chat bot.

BotDJ.txt: a bot can play music in Active Worlds, it
can be further extended to do other actions such as
slide shows and etc.
