This is a plugin for Godot Engine to create and edit graphs of cutscenes and dialogue resources.
Only Godot version 4 is supported by this incarnation of the plugin. An earlier version of this plugin that supported Godot 3 is available in this repository.
Download the source and move/copy the contents of the addons directory to the addons directory of your Godot project.
This plugin is still very much a work in progress, so more documentation will follow when it is more fully developed.
