Unity实现物件挂载到不同父节点

首先需要一个物件对象

public class KitchenObject : MonoBehaviour
{
    public KitchenObjectHolder Holder { get; set; }

    public void ResetHolder()
    {
        if (Holder == null)
            return;

        Holder.KitchenObject = null;
        Holder= null;
    }

}

然后是物件持有者对象

public class KitchenObjectHolder :MonoBehaviour
{
    [SerializeField]
    private Transform kitchenObjectParent;

    public KitchenObject KitchenObject { get; set; }

    public Transform GetKitchenObjectParentTransform()
    {
        return kitchenObjectParent;
    }

    public void TrySwapKitchenObject(KitchenObjectHolder another)
    {
        MoveKitchenObject(this, another);
    }

    private static void MoveKitchenObject(KitchenObjectHolder holder1, KitchenObjectHolder holder2)
    {
        if ((holder1.KitchenObject!=null) && (holder2.KitchenObject!=null))
            return;

        if ((holder1.KitchenObject==null ) && (holder2.KitchenObject==null))
            return;


        if(holder1.KitchenObject != null)
        {
            holder2.HoldKitchenObject(holder1.KitchenObject);
        }
        else if(holder2.KitchenObject != null)
        {
            holder1.HoldKitchenObject(holder2.KitchenObject);
        }

    }


    public bool HoldKitchenObject(KitchenObject kitchenObject)
    {
        if (this.KitchenObject != null)
            return false;

        kitchenObject.ResetHolder();

        kitchenObject.Holder = this;
        this.KitchenObject = kitchenObject;

        kitchenObject.transform.parent = GetKitchenObjectParentTransform();
        kitchenObject.transform.localPosition = Vector3.zero;

        return true;
    }
}

代码的核心逻辑就是将物件的transform的parent设置为持有者对象上的一个transform。
然后制作prefab。
