Beehave is a behavior tree AI framework for Godot Engine that enables developers to structure game AI using hierarchical decision-making trees.

Behavior trees solve the problem of organizing complex AI logic by breaking it into reusable, composable nodes that represent decisions and actions. Beehave implements this pattern as a Godot plugin, allowing developers to define AI behavior through a tree structure where composite nodes manage control flow, decorator nodes modify behavior, and leaf nodes execute concrete actions or checks. The framework integrates directly with Godot's node system, making it natural to attach AI logic to game entities.

Beehave suits projects where AI needs to be readable, maintainable, and iteratively refined. It works well for games with multiple agents that share behavioral patterns, since tree nodes can be reused across different characters. The tool is appropriate for developers who prefer explicit, visual representations of decision logic over scripted state machines or monolithic AI classes. Projects ranging from simple enemy patrol routines to complex multi-agent coordination can benefit from the structure behavior trees provide.

The project shows consistent maintenance with regular updates addressing both Godot 3 and Godot 4 compatibility. Development activity demonstrates responsiveness to issues and pull requests, with fixes and enhancements being integrated steadily. The codebase maintains clear separation between core behavior tree logic and Godot integration points, suggesting deliberate architectural choices. Documentation through the homepage and README examples provides practical guidance for common use cases, though the scope remains focused on the behavior tree pattern itself rather than attempting to be a comprehensive AI toolkit.
