Screenwriter is a tool for creating Screenplay, which could be Dynamic Cutscenes, Interactive Character Dialogue or even complete story progression, that can be easily integrated with your existing game systems.

  • Supported Platforms
  • Supported Engine Versions


Screenwriter is a Code Plugin featuring Actors, Assets Types and a Graph Editor for creating in-game dynamic Cutscenes, Interactive Character Dialogue scenes, and various other story-driven gameplay elements.

The Primary feature is the ability to implement “Acts” for your game using the Act asset and its associated supporting types. Acts are used by important scenes in your game to control the scripted sequence of events they are made from, such as Characters speaking, playing animations and updating the players progression.

The Plugin has a minimal initial footprint and is designed to be extended by Gameplay Programmers, with their additions and / or modifications reflected in the Details panel of the Act asset Graph Editor.

The Graph Editor, styled much like Blueprints, allows you to create the sequences of Actions, add optional Directions during Actions, and Branch to different sequences of Actions based on dynamic in-game Conditions, like checking distances or "has the player completed mission X".
