Parlite is a free, no-nonsense dialogue system for Unity. If your game needs characters to talk, branch, and react to player choices, without you wrestling with a bloated framework, this is for you.

You pick how you write dialogue. Prefer typing? Use plain YAML files. Prefer clicking? Use the built-in visual graph editor. Both output the same runtime, the same API, and the same clean async C# you can drop into any project in minutes.

🗂️ Authoring

Two workflows, one runtime. Write dialogue in plain YAML or build conversations visually with the node-based graph editor, whichever fits your team and your pipeline.

- Visual graph editor with Dialogue, Choice, Branch, Start, and End nodes

- YAML authoring with the same node types in a readable, portable format

- Flag system for setting and checking state across nodes — drive branching without scripting

- Emotion tags on dialogue nodes for expressive, reactive characters

- Localization-ready file structure with built-in LTR/RTL text direction support

- Graph editor requires Unity 6+; YAML works with all supported Unity versions

🎮 Runtime & API

Parlite's runtime is intentionally lean. You get exactly what you need to drive a conversation loop and nothing you don't.

- Async/await API — await dialogue.OnNextDialogue to advance, or subscribe to events

- ParleyYaml and ParleyGraph classes share the same interface so switching authoring modes costs nothing

- GetCurrentChoices(), ChoiceMade(int), and GetPlayerChoice() handle branching cleanly

- Rebind the advance input action at runtime via BindNextEvent() / UnBindNextEvent()

- Graceful handling of invalid nodes and indices — dialogue ends cleanly instead of throwing

📦 Samples Included

Every sample ships in two UI flavors — UGUI and UI Toolkit — so you can hit the ground running regardless of your UI setup.

- Hello Parley: the simplest possible dialogue loop to get you oriented

- Choices: branching dialogue with player-selectable options

- Emotions: dialogue with emotion tags driving character expression

- Common assets and shared UI resources included

Parlite is the free tier of Parley, capped at 5 nodes and 2 choices per node. Great for prototypes, game jams, and small scoped projects. When you need more, upgrading to Parley unlocks unlimited nodes, choices, aliases, and full localization support.
