State Pattern Example

A Unity example demonstrating the State Pattern with a game onboarding system.

Overview

The State Pattern allows an object to alter its behavior when its internal state changes. In this example, we use it to manage different states of a game onboarding system, where each state represents a different tutorial phase.

Implementation

• IState.cs: Base interface for all states
• StateMachine.cs: Manages state transitions
• OnboardingManager.cs: Handles onboarding logic
• States:
  • MovementTutorialState.cs: Teaches basic movement
  • CombatTutorialState.cs: Teaches combat mechanics
  • InventoryTutorialState.cs: Teaches inventory usage

Usage

// Setup is automatic - just add to a GameObject
OnboardingManager manager = gameObject.AddComponent<OnboardingManager>();

// States will transition automatically as player completes each tutorial phase
// You can also manually transition if needed:
manager.ChangeState(new CombatTutorialState());

Benefits

• Clean separation of tutorial phases
• Easy to add new tutorial states
• Clear state transitions
• Centralized tutorial management
