Branching paths for a text based adventure game (language agnostic)

How would i create a system of branching paths for a text based adventure game? i dont want it to devolve into a ton of if-statements because i have done that before and it is a mess to keep track of and maintain

✅ confused by this error

class Player(Vector2 position, Vector2 size) {
    public Vector2 Position { get; } = position;
    public Vector2 Velocity { get; private set; } = Vector2.Zero;
    public Vector2 Size { get; } = size;

    public Rectangle GetRect() {
        return new(Position, Size);
    }

    public void Input() {
        float dt = GetFrameTime();
        Velocity.X = 0.0f;
    }
}

class Player(Vector2 position, Vector2 size) {
    public Vector2 Position { get; } = position;
    public Vector2 Velocity { get; private set; } = Vector2.Zero;
    public Vector2 Size { get; } = size;

    public Rectangle GetRect() {
        return new(Position, Size);
    }

    public void Input() {
        float dt = GetFrameTime();
        Velocity.X = 0.0f;
    }
}

Cannot modify the return value of 'Player.Velocity' because it is not a variable in the Input method all i am doing is modifying the field of the struct, why is that a problem?

✅ Strange output of my code

        var query = Enumerable.Range(1, 1000)
            .Where(x => x % 2 == 0)
            .Aggregate((x, y) => x * y);

        Console.WriteLine(query);

        var query = Enumerable.Range(1, 1000)
            .Where(x => x % 2 == 0)
            .Aggregate((x, y) => x * y);

        Console.WriteLine(query);

why does this output 0? is it due to overflow, and if it is, why is an exception not thrown?

✅ `T` always value for `nameof`

        int id = nameof(T).GetHashCode();
        Console.WriteLine(nameof(T));

        int id = nameof(T).GetHashCode();
        Console.WriteLine(nameof(T));

how come nameof(T) always returns T instead of the type of the generic argument?

✅ Pass in arguments to a generic constructor

    public T AddComponent<T>() where T: Component, new() {
        Component component = new T(this);
        return (T)AddComponent(component);
    }

    public T AddComponent<T>() where T: Component, new() {
        Component component = new T(this);
        return (T)AddComponent(component);
    }

i want to be able to create new instances of T in the method, but i get the error 'T': cannot provide arguments when creating an instance of a variable type. how can i make this work? one precondition is that all child of Component will only have one argument in their constructor

✅ Get type of current instance in a static method

    public static int GetTypeId() {
        return typeof(TypeOfInstance).Name.GetHashCode();
    }

    public static int GetTypeId() {
        return typeof(TypeOfInstance).Name.GetHashCode();
    }

how can i get the current type of the current class? this class will be inherited by other classes, and i need to get the hash code of the name of the class
