Write the conversation. Connect it to your world.
IsoAssets Dialogue Toolkit is a source-included Unity toolkit for branching conversations, visual authoring, live debugging, localization and coordinated saves.
Build dialogue with consequences
- Author Line, Choice, Branch, Action, Jump and End nodes in a visual graph and searchable outline. Connect named destinations and undo your edits.
- Use typed Boolean, Number and Text variables, shared world state, conditional responses and once-only history across NPC conversations.
- Inspect live state, decision traces and transcripts while testing the same runtime your game uses.
- Round-trip translation CSV, switch language catalogues and fall back to source text.
- Keep cosmetic edits compatible with saves; use explicit, validated session migration plans for intentional execution changes.
- Use the themed, scrolling IMGUI panel or integrate your own presentation and input.
A sample that changes the game world
Watch Gate includes three NPC conversations, an inventory command boundary, shared quest state and a physical gate. Buy medicine, save, deliver it and reload: inventory, quest, conversation and gate restore together. A Spanish catalogue, original portrait silhouette and synthetic audio cue demonstrate presentation bindings.
Inside the download
Version 1.0.0: editable runtime/editor/sample C#, importable Watch Gate sample, UPM tarball, installation guide, manual, compatibility notes, changelog and single-entity license. No paid dependencies or runtime AI service required.
Compatibility and scope
Tested on Unity 6000.3.27f1 and 6000.6.7f1, Windows x64 / Mono / D3D11. The sample scene uses Built-in; the core and IMGUI view do not require a render pipeline. Qualification covers 58 regression checks, package/sample import, a successful Windows build and 13 standalone workflow checks per tested engine. Unity 6.3 also verifies the exact customer tarball. Checks run on one workstation.
This is a dialogue toolkit, not a complete quest/inventory/RPG framework. Recorded voice acting, polished promotional game artwork, a ready-made Input System adapter, full RTL shaping and cinematic sequencing are not included. Other platforms, IL2CPP, URP/HDRP sample materials and physical controllers are unqualified. The default controls use legacy input.
Installation
Extract the ZIP. In Unity Package Manager, install com.isoassets.dialogue-1.0.0.tgz using the package-from-tarball action. Import Watch Gate integration from Samples and open WatchGate.unity under Assets/Samples. Start writing through Tools > IsoAssets > Dialogue Studio. Read START-HERE.txt and Manual.md before integrating host commands or game saves.
