更好的方法：混合枚举或2个枚举

Question

我有两种移动的对象 - 盒子和汽车 - 移动有些不同。

方框：设置向右移动时，向左，向上或向下将移动1像素到所需的方向。

汽车：设置向右移动或向左移动时 - 将顺时针/逆时针旋转。当设置向前/向后移动时 - 将根据汽车的脸部和背面移动。因此，如果汽车旋转45度，我们将其设置为向前移动，则汽车将向右侧半像素和半像素（假设汽车启动朝上）。

我想知道以下哪种是更好的方法，或者有更好的方法：

public abstract class MovingObject
{
    public abstract void Move();

    public enum Direction { UP, DOWN, LEFT, RIGHT, FORWARD, BACKWARD }

    public Direction CurrentDirection { get; set; }

    //some other fields and properties


    public class Box : MovingObject
    {
        public override void Move(){...}
        //some Box related things
    }


    public class Car : MovingObject
    {
        public override void Move(){...}
        //some Car related things
    }
}

public abstract class MovingObject
{
    public abstract void Move();

    //some fields and properties


    public class Box : MovingObject
    {
        public enum Direction { UP, DOWN, LEFT, RIGHT }

        public Direction CurrentDirection { get; set; }

        public override void Move(){...}
    }


    public class Car : MovingObject
    {
        public enum Direction { FORWARD, BACKWARD, LEFT, RIGHT }

        public Direction CurrentDirection { get; set; }

        public override void Move(){...}
    }
}

我建议创建两个枚举和一个通用基类，以枚举，代码看起来像这样。

public enum BoxDirection
{
    UP,
    DOWN,
    LEFT,
    RIGHT
}

public enum CarDirection
{
    LEFT,
    RIGHT,
    FORWARD,
    BACKWARD
}

public abstract class MovingObject<T> where T: Enum
{
    public abstract void Move();

    public T CurrentDirection { get; set; }

    //some other fields and properties


    public class Box : MovingObject<BoxDirection>
    {
        public override void Move() { ... }
        //some Box related things
    }

    public class Car : MovingObject<CarDirection>
    {
        public override void Move() { ... }
        //some Car related things
    }
}
