效果图如下：

其实很简单，在NGUI原有的滑动组件的基础上处理一下比例系数就好，每个块的位置是固定的，移动的是Panel。

所以呢用Panel的位置与块的位置做差在比几个块不就成了比例系数了么。。自然就出来了，最后在处理一下层级就ok了。

代码如下（我是生成的10个块）：

using UnityEngine;using System.Collections;public class test : MonoBehaviour {    private GameObject mItem;    private GameObject[] Items = new GameObject[11];    private Vector3 Pos = new Vector3(0, 0, 0);    private bool begin = false;    void Start()    {        mItem = transform.Find("Item").gameObject;        for (int i = 9; i >= 0; i--)        {            Clone(i);        }        begin = true;      }    void Clone(int i)    {        GameObject _clone = Instantiate(mItem) as GameObject;        Pos.x = 100 * i;        _clone.transform.SetParent(gameObject.transform);        _clone.transform.localPosition = Pos;        _clone.transform.localScale = Vector3.one;        _clone.SetActive(true);        Items[i] = _clone;    }    void Update()    {        if (begin)        {            float max = 0;            int j = 0;            for (int i = 0; i < 10; i++)            {                Vector3 Ipos = Items[i].transform.localPosition;                float factor = Mathf.Abs(Ipos.x + gameObject.transform.parent.transform.localPosition.x);                factor = 1 - factor / 1000;                Vector3 p = Vector3.one * factor;                p.x = 1;                Items[i].transform.localScale = p;                if (factor > max)                {                    max = factor;                    j = i;                }            }            for (int i = 0; i < 10; i++)            {                if (j != i)                {                    Items[i].GetComponent
     
      ().depth = 1;                }                else                {                    Items[i].GetComponent
      
       ().depth = 2;                }            }        }    }}
