Game Programming Architecture

Design Patterns for Games

1. State Machine

Best for: Character states, AI, game flow

// ✅ Production-Ready State Machine
public abstract class State<T> where T : class
{
    protected T Context { get; private set; }
    public void SetContext(T context) => Context = context;
    public virtual void Enter() { }
    public virtual void Update() { }
    public virtual void Exit() { }
}

public class StateMachine<T> where T : class
{
    private State<T> _current;
    private readonly T _context;

    public StateMachine(T context) => _context = context;

    public void ChangeState(State<T> newState)
    {
        _current?.Exit();
        _current = newState;
        _current.SetContext(_context);
        _current.Enter();
    }

     => _current?.Update();
}


   : <>
{
     => Context.Animator.Play();
    
    {
         (Context.Input.magnitude > )
            Context.StateMachine.ChangeState( PlayerMoveState());
    }
}
