Dialogue on GS_Play Gameplay Framework

Dialogue System

Mon, 01 Jan 0001 00:00:00 +0000

The Dialogue System is the authoring and runtime core of GS_Cinematics. Dialogue content is stored in .dialoguedb assets (DialogueDatabase), which contain named actors and a collection of DialogueSequence records. Each sequence is a graph of polymorphic nodes. At runtime, GS_DialogueManagerComponent manages the database and maps performer names to entities in the level, while DialogueSequencerComponent drives playback — walking the graph, evaluating conditions on branches, executing effects, and emitting events that UI and other systems consume.

GS_Cinematics

Mon, 01 Jan 0001 00:00:00 +0000

GS_Cinematics is the complete dialogue and cinematic control system for GS_Play. It provides a node-graph authoring tool for branching dialogue sequences, a runtime sequencer with conditions and side effects, a UI layer for text display and player choice, and a Cinematics Manager for scene staging. Custom conditions, effects, and performance types are discovered automatically through O3DE serialization, so project-specific dialogue behaviors can be added without modifying the gem.

For architecture details, component properties, and extending the system in C++, see the GS_Cinematics API.

Dialogue UI

The Dialogue UI layer is the display side of the GS_Cinematics system. It receives events from DialogueSequencerComponent through DialogueUIBridgeComponent and routes them to the correct UI implementation — screen-space for HUD-style dialogue or world-space for speech bubbles above actors. Player choices are handled by selection components, and the TypewriterComponent reveals text character-by-character. BabbleComponent optionally plays per-character audio babble to give speakers a voice.

For architecture details, component properties, and extending the system in C++, see the Framework API reference.

Performances

Mon, 01 Jan 0001 00:00:00 +0000

Performances are polymorphic actions that move or reposition actors during dialogue sequences. The sequencer triggers a performance when it reaches a PerformanceNodeData node and waits for OnPerformanceComplete before advancing. This async model lets multi-step actor choreography complete fully before dialogue continues. Three built-in performance types cover direct movement, navmesh navigation, and instant teleportation. Custom types can be created by extending the base class.
