FluadHTN

FluadHTN is a Lua port of the FluidHTN framework, providing a hierarchical task network (HTN) planner for AI decision-making. It enables the creation of complex, goal-oriented behaviors by decomposing high-level tasks into executable primitive actions through forward decomposition.

Key Features

• Total-Order Forward Decomposition — Plans by recursively decomposing compound tasks into primitive actions.
• Partial Planning — Supports pausing and resuming plans within sequences for dynamic execution.
• Domain Splicing — Combines sub-domains at design-time or run-time via slots for modular AI design.
• Early Replanning Rejection — Optimizes performance by avoiding unnecessary replanning when world state changes won't affect the plan.
• Factory Interface — Allows custom memory management schemes like object pooling.
• Decomposition Logging — Provides debugging tools to trace planning decisions.
• Minimal Dependencies — Easily integrable into Lua environments like LÖVE, Defold, Roblox, and MWSE.

Philosophy

FluadHTN emphasizes extensibility and performance, offering a clean separation between planning and execution while maintaining a lightweight, portable codebase suitable for game AI and simulation contexts.
