Dialouge & Quest Pack - Extension Pack for BTGraph

Build Complete Conversations — Not Just Trees

BTGraph – Dialogue & Quest Pack transforms your behaviour trees into fully interactive narrative systems.

Create branching dialogue, conditional choices, quest-aware conversations, and reactive NPC interactions — all inside the BTGraph editor.

No custom nodes required.
No hard-coded logic.
No external dialogue framework needed.

🎭 Dialogue Features

• Start / End Dialogue nodes
• Dialogue Line node (speaker, tags, optional metadata)
• Choices node with:
  Visible conditions
  Enabled conditions
  On-select effect lists
• Jump / Flow control
• Continue / Await input
• Random / Weighted dialogue (barks support)
• Once & cooldown gating

The included Dialogue Runner and Simple UI prefab allow immediate use without writing additional systems.

🧭 Quest Integration (Out of the Box)

Connect dialogue directly to your quest logic.

• Offer, complete, fail quests
• Set and advance quest stages
• Add quest progress
• Set / clear flags
• Raise quest events
• Wait until quest conditions are met
• Branch based on quest state, stage, progress, or flags

Includes a lightweight SimpleQuestService for immediate testing and prototyping.

For production use, implement the provided IQuestService interface to connect your own quest system seamlessly.

⚙️ Professional Architecture

Designed with clean integration in mind:

• UI-agnostic runtime (event-driven Dialogue Runner)
• Blackboard-compatible service resolution
• Minimal allocations and tick-safe nodes
• Modular design that extends BTGraph cleanly
• Works with existing BTGraph projects

This pack does not replace your quest system — it connects to it.
