Unity Finite State Machine (FSM)

This skill provides a modular, object-oriented State Machine architecture for Unity, specifically refactored to match the implementation in Adam Myhre's 3D Platformer.

Core Features

• Object-Oriented: Each state is a dedicated class.
• Hybrid Support: Support for both "Heavy" (classes) and "Light" (ActionState) states.
• Strategy-Based Transitions: Uses Predicates and Detection Strategies.
• Timer System: Includes Adam Myhre's CountdownTimer and StopwatchTimer.
• Namespace Support: Uses Platformer and Utilities namespaces.

Core Files (assets/code/)

• IState.cs.txt, StateMachine.cs.txt, IPredicate.cs.txt: Base FSM logic.
• ActionState.cs.txt: New! Lambda-based state to reduce boilerplate.
• Timer.cs.txt: AI cooldown management.
• IDetectionStrategy.cs.txt, ConeDetectionStrategy.cs.txt: Sensing logic.
• PlayerDetector.cs.txt, Enemy.cs.txt, EnemyBaseState.cs.txt: AI templates.

Implementation Pattern

1. Define your states by inheriting from BaseState.
2. Wire them in your PlayerController or EnemyAI using stateMachine.AddTransition.
3. Execute via Update() and FixedUpdate() calls to the machine.
