Documentation

Step-by-step guides, conceptual references, and copy-pasteable tree patterns. Everything here uses the actual editor running at bteditor.dev — open the link in any tutorial and you'll see the same tree as the screenshots.

Getting started

• Getting started

  Build your first behavior tree in under five minutes. From opening the editor to exporting a working JSON.

• Node types reference

  Every Composite, Action, Condition, and Decorator node that ships in the default library, with a worked example of each.

• Import & export formats

  JSON, XML, and BehaviorTree.CPP formats — when to use which, and how to round-trip between them.

How-tos

• Replay NDJSON execution logs

  Capture a behavior tree run as NDJSON, replay it in the editor with step/pause controls, and share the file with teammates.

• Live monitor via WebSocket

  Push real-time node status from your robot or game server to the editor over a single WebSocket connection.

• Define custom node types

  Add your own Composite / Action / Decorator nodes with typed ports, and ship them as a JSON library.

Patterns & theory

• Reactive control patterns

  Why behavior trees, when to use them over state machines, and common architectural pitfalls.

• Interop with BehaviorTree.CPP

  Round-tripping trees with the popular C++ library: how to map ports, register custom types, and stay compatible.

• Behavior trees in robotics

  A short essay on applying reactive trees to mobile robot navigation, manipulation, and multi-robot coordination.
