HFSM2: High-Performance Hierarchical Finite State Machine Framework
Header-only heriarchical FSM framework in C++14, with fully statically-defined structure (no dynamic allocations), built with variadic templates.
Compiler Support
- Visual Studio 14, 15, 16
- GCC 5, 6, 7, 8, 9
- Clang 3.7, 3.8, 3.9, 4, 5, 6, 7, 8, 9, 10
Documentation
Old Wiki docs are being upgraded and moved to the New GitBook.
In-line comment-based docs is an on-going effort.
Feature Highlights
- Permissive MIT License
- Written in widely-supported modern(ish) C++11
- Header-only
- Convenient, minimal boilerplate
- Fully static, no dynamic allocations
- Uses inline-friendly compile-time pylymorphism, no virtual methods were harmed
- Type-safe transitions:
FSM.changeTo<TargetState>() - 100% NoUML-compliant
- Hierarchical, with a selection of composite (sub-machine) and orthogonal regions
- Gamedev-friendly, supports explicit
State::update() - Also supports traditional event-based workflow with
State::react() - AI-friendly with Dynamic planning support
- Utility theory support (both max score and ranked weighted random)
- Scaleable, supports robust state re-use via state injections
- Debug-assisted, includes automatic structure and activity visualization API with
#define HFSM_ENABLE_STRUCTURE_REPORT - Serializable, with activity and transition history support
- Built-in logging support
