Unreal Engine – Blueprint Dialogues

Video:

Built using Blueprint/UMG and actor components, this dialogue and scripting system enables developers to quickly create dialogue content, empowered by a data-driven design with a myriad of inline text formatting tools and configurable interface options.

Branching and non-branching styles of dialogue are supported; which to use is determined at run-time, according to the response options provided by the developer.

With a data-driven design, content creators are free to choose to work in a spreadsheet editor, or directly in UE4's datatable row editor.

The system can be used for basic text-only dialogue or for more complex conversations with non-linear dialogue; text formatting; inline images; variable text; audio playback; scripted event triggers and conditions; and custom interface layouts.

Technical Details

A set of Actors, Actor Components, and UMG Widgets make up the dialogue system

A default use/interact system is provided as a component based implementation.

Each actor can have one or many dialogue components, allowing for multiple layouts and data tables.

A Speaker Attribute component can optionally be added to give a name and/or portrait to the speaker
