AI in RPGs

• AI is a semi-rare element in most RPGs
• Most events are scripted (logic)
• Human interaction generally has minimal effect on
  Non-player character (NPC) actions.
• Example WoW Raid Encounter

5
Massively Multiplayer Online RPGs

• MMO RPGs require even less AI than single-player
  RPGs
• Human players are the natural intelligence which
  takes the place of AI
• In todays game market, the focus is very heavy
  on multiplayer, so AI is fading more and more
  from these games

6
HCI in RPGs

• Human-Computer Interaction is the driving element
  in most RPGs
• Most RPGs allow interaction through a User
  Interface (text or graphical)
• Most RPGs use an event-driven scheme for HCI
• Ex. You cast a spell at an enemy, which causes
  the enemy to retaliate

HCI Elements

Environment

• The environment is the medium to communicate to
  the world and other players
• Players can use an array of elements to
  communicate, such as visual gestures, textual
  chat, or auditory notions.
• Of course, throwing a fireball in someones face
  is a good form of communication as well

9
Language-based Communication

• Of all the communication means, language-based
  communication is the most widely used in RPGs
• In single player, you talk to NPCs to obtain
  quests and further understand of the story line.
• In multiplayer, you talk to NPCs as well as other
  players to achieve common goals
