## What it is
behaviac is a game AI development framework from Tencent supporting behavior trees, finite state machines, and hierarchical task networks. It includes a Windows-only visual designer for authoring and debugging behaviors, with C++ and C# runtime libraries that run on all major platforms including Unity.

## Use cases
- design NPC AI with behavior trees for a Unity game
- implement enemy state machines using FSM or HTN
- rapidly prototype game AI logic in a visual editor
- share behavior definitions between client and server game code
- debug game AI behaviors in real time during play

## When to choose
- you need behavior trees, FSMs, or HTN for game AI in C++ or C#/Unity
- you want a visual designer with live debugging for game behaviors
- you need cross-platform runtime support for client and server game AI

## When to avoid
- you need a designer on macOS or Linux (designer is Windows-only)
- you are building non-game agent systems better served by modern agent frameworks
- you need a project with frequent updates and active community maintenance

## Facets
- artifact type: framework
- maturity: maintenance
- function: game-engine, simulation, developer-tools
- domain: artificial-intelligence, gaming-tools
- platform: windows, cpp, c, cross-platform
- tags: behavior-tree, fsm, htn, game-ai, unity, visual-designer, csharp, game-development, linux, macos, android, ios
