NGUI 背包系统的拖拽

1.使用拖拽脚本进行拖拽

2.通过重写脚本

using UnityEngine;

using System.Collections;

public class MyDraDropitem : UIDragDropItem {

    protected override void OnDragDropRelease(GameObject surface)

    {

        base.OnDragDropRelease(surface);

        if (surface .transform.childCount>0)

        {

        }

        else

        {

        }

        this.transform.parent = surface.transform;

        this.transform.localPosition = Vector3.zero;

    }

}

3.通过节点

using UnityEngine;

using System.Collections;

public class Knapsack : MonoBehaviour {

public GameObject[] cells;

}

数组来确定cell的 位置
