What This Is​

Behavior Tree Editor provides a general solution to model agents for games and other applications, such as simulations and robotics. It is built on the Behavior3 model, which is based on a formal description of behavior trees.

  • Custom Nodes — Create your own node types inside one of the four basic categories: composite, decorator, action or condition.
  • Individual Node Properties — Modify node titles, descriptions and custom properties.
  • Manual and Auto Organization — Drag nodes around, or press a to auto-organize the whole tree.
  • Multiple Trees — Create and manage an unlimited number of trees.
  • Import / Export to JSON — Export your project, tree or nodes to JSON. Import them back. Use the JSON in your own library or tool.

About This Fork​

This is a maintained fork of the original behavior3editor created by Renato de Pontes Pereira. The original project is no longer actively maintained. This fork:

  • Merges community pull requests that were pending for years
  • Modernizes the build toolchain (Electron, current Node)
  • Ships desktop binaries via GitHub Releases

See the Changelog for the full history.

Companion Runtime​

To execute the trees you design here, use the companion runtime henrytien/behavior-tree — a behavior tree implementation in Go. Export your tree to JSON and load it there.
