Feedback to utterances initiated by players or simply utterances by [[NPCs]] can take several forms in [[Dialogues]].

Diegetic conversations controlled by a game systems.

This pattern is a still a stub.

Note: Many of the patterns concerning dialogues were first identified in the research reported in chapter 3 of the PhD thesis Steps Towards Creating Socially Competent Game Characters[1] by Jenny Brusk. This thesis also describes how to model dialogues in Harel statecharts.

Examples

Dragon Age series Mass Effect series Fallout series

Zork series MUD2 DragonMud

Grim Fandango

Using the pattern

The main distinction between different Dialogues in games is whether they are used to communicate directly with the game system, i.e. create Illocutionary Interfaces, or are used to communicate with Characters in the Game Worlds.

Non-Player Characters Companions Helpers

Indirect information

Detective Structures

Clues

Outspoken Support Requesting Support Basic Input Feedback


Game State Indicators Ephemeral Goals Quests Inaccessible Areas

While many dialogue systems are Single-Initiative Dialogues in that players need to activate them for them to occur, another possibility is that of Mixed Initiative Dialogues where Non-Player Characters can start the Dialogues with players. Examples of when this occurs is in the Elder Scrolls series and Fallout series. Regardless of who starts a dialogue, another design choice is how players create their utterances and commit to having them said. Choosing one out of several options (as in Grim Fandango and the Dragon Age and Fallout series) or letting player write complete free-text sentences (as in DragonMud or the Zork series) are examples Chunk-based Dialogue Processing but a lesser explored option is that of Incremental Dialogue Processing. This, which is found in Facade, lets the Dialogues be Gameplay Integrated Conversations. The main purpose of this it to help contain Diegetic Consistency so that not for example a pursuit may be completely halted as the players initiates a conversation with some random NPC. Any Dialogue system can provide Gameplay Integrated Conversations simply by running in parallel with other event loops in the game but this requires players to shift between the modes; Incremental Dialogue Processing makes these shifts simpler.

Feedback to utterances initiated by players or simply utterances by NPCs can take several forms in Dialogues. The simplest to creates is Canned Text Responses but Context Dependent Dialogues provide Contextualized Conversational Responses. This may be done by algorithmically creating utterances as the Dialogues unfold, but Location-Specific Dialogues and Character-Specific Dialogues may be sufficient to make the Dialogues seem context dependent without requiring advance parsing and text generation systems.

Challenges can be added to the difficulty of using Dialogues. For example, players may need to use Delicate Phrasing (as in some of the challenges in Grim Fandango) or require Colloquial Mastery. When the Dialogues are with Non-Player Characters further options opens up for designing for skill requirements regarding Brokering, making False Accusations, or Maintaining Lies. Ambiguous Responses from Non-Player Characters also increases difficulty in Dialogues, making players have to guess or create hypotheses about the true meaning of utterances.

While Dialogues consist of Information Passing, what can be said in one Dialogue can be modified by the knowledge the player has acquired earlier, i.e. through earlier Information Passing. One specific types of Information Passing that can serve in both these ways (and as Clues) is Gossip.

Diegetic Aspects

Given that many Dialogues take place between Characters in Game Worlds, they need to be crafted to fit the game's setting if the game should have Diegetic Consistency. This primarily consists of making sure one has Thematically Consistent Dialogues unless Contextualized Conversational Responses provide this already.

Interface Aspects

Dialogues are either an interface or the interface to the game in which it exists, so the pattern is a.

A major limitation to the complexity of Dialogues or Contextualized Conversational Responses is when they are to be communicated partially or wholly by voice acting.

Narrative Aspects

Narration Structures are typically created through Dialogues since many Dialogues are created so the series of utterances made will have a casuality.

Consequences

Dialogues are a form of Communication Channel. All statements in Dialogues are examples of Information Passing but the ones that also change the game state are in addition Performative Utterances. When a game's interface is a Dialogues, the game has a Illocutionary Interface.

History

While many of the patterns discussed as part of this pattern have been described by Brusk[1] and others, the pattern Dialogues in itself was created in this wiki.
