Behavior trees organise what an AI character does into a hierarchy of decisions and actions, which keeps complex NPC logic readable as it grows. Behavior Designer sits in the Tools and Behavior AI category and brings that approach to Unity, so AI logic can be built as a structured tree instead of a growing pile of conditional code.
The asset is a behavior tree tool for authoring AI behaviour in Unity projects. It works with the Built-in Render Pipeline, URP and HDRP across Unity 6 and 2022 LTS, so it fits a wide range of project setups. Among unity AI tools, a behavior tree editor suits teams who want designers and programmers to reason about NPC behaviour in the same structured way.
