LSDEDELSDE Dialog Engine

Multi-runtime, callback-driven graph dispatcher for interactive dialogue blueprints

playground.ts

// Blueprint → Engine → Handlers → Game

const engine = new DialogueEngine();

engine.init({ data: blueprint });

engine.setLocale('en');

engine.onDialog(({ block, next }) => {

showUI(block);

next();

});

engine.scene('quest-01').start();

Visual Blueprints

Consume JSON exports from the LSDE editor — scenes, blocks, connections, dictionaries, signatures.

Available in TypeScript, C#, C++, and GDScript. Same blueprint format, same test suite, native integration.

No internal render loop. The engine dispatches blocks to registered handlers; the host application controls the flow.

The engine is a pure graph traversal machine. The 4 handlers give meaning to each block — no hidden fallbacks, no auto-evaluation.
