子类稍有不同

Question

我真的不知道该如何寻找解决方案，因为它看起来如此抽象，所以我在这里。

例如，如果我有一个基类public abstract class BuildingBaseObject，然后有2个子类，其中一个包含RuleTile变量，另一个包含GameObject变量，则可以通过某种方法从单个函数（在另一个类中）访问这两个变量之一？我不想使用object关键字，因为它会破坏类型的持久性，并且根本无法与我的代码一起使用。

可重复代码

public abstract class BuildingBaseObject {
    //Irrelevant Stuff
}

public class BuildingTile : BuildingBaseObject
{
    public RuleTile ruleTile;
}

public class BuildingObject : BuildingBaseObject
{
    public GameObject objectTile;
}

public class UIShipItem : MonoBehaviour {

    Object buildingObject;
    public object BuildingObject
    {
        get
        {
            if (buildingObject is BuildingObject) return buildingObject as BuildingObject;
            else if (buildingObject is BuildingTile) return buildingObject as BuildingTile;
        }
        set
        {
            if(value is BuildingObject) buildingObject = value as BuildingObject;
            if(value is BuildingTile) buildingObject = value as BuildingTile;
            gameObject.GetComponent<Image>().sprite = (buildingObject as BuildingBaseObject).sprite;
        }
    }

}

是否有一种方法可以很好地做到这一点，或者我应该为BuildingBaseObject的每个子类创建一个UIShipItem基类和不同的子类？

我不是Unity编码器，但是就C＃而言，它可以工作：

public class UIShipItem<T> : MonoBehaviour where T : BuildingBaseObject
{
    T buildingObject;
    public T BuildingObject
    {
        get
        {
            return buildingObject;
        }
        set
        {
            buildingObject = value;
            gameObject.GetComponent<Image>().sprite = buildingObject.sprite;
        }
    }
}

您将这样使用它：

var x = new UIShipItem<BuildingTile>();
