Joint is a plugin that provides the most flexible gameplay control, especially specialized for dialogue-based interaction scripting framework available on the scene.

Joint is a system where you can attach and joint fragments - a module contains data or gameplay control logic set for its lifecycle - on the graph to make something bigger production.

Yes, you heard it right. It's actually a new gameplay control system like GAS and Flow-graph, but specialized for dialogue systems. so technically, you can even make gameplay systems like combo systems, quest systems, minigames, etc. Now I regret just advertising it as a dialogue system - while It's more than a simple dialogue system that displays subtitles.

To use all the features of Joint, please install Joint-Native - An open-source plugin for Joint's basic contents and assets.

▶ Blueprint Support

There is no bottleneck even if you only use BP, we actually encourage you to use BP on fragments to quickly iterate your development.

▶ Complete Networking Support

Joint supports full-networking support (Replication, RPC functions). via those, you can make something like making players vote among options for the next branch, or wait until all players finish their task or until they agree to move on to the next line.

▶ NEXT-LEVEL Localization Support

Your production with Joint will be automatically matched with localized contents thanks to its module-based playback design: no more non-synchronized texts and other productions after localization.

▶ Error-Free Supports

Joint lets no bug slip through the actual product. use Dialogue Debugger, Dialogue Compiler will help you catch all the bugs before you release, even halt the packaging when it senses major issues.

▶ Tripple A Editor QOL Features

No headache with editing. use the WYSIWYG text editor, Convenient Node picking, Search & Replace in dialogues to maximize your productivity.

▶ Another level of Supporting Service

You have something not working right? Just bring it to us, we will make it for you FOR FREE. Just visit our discord, and we will walk through your journey with you. We've done this since when this product was called SDS (simple dialogue system) and everyone liked it. (please check out the review back then!)
