Unity 跑马灯抽奖效果实现代码，供大家参考，具体内容如下

这边用到插件是NGUI+Dotween，思路简单说下：先排版，通过移动图片蒙版来实现效果。
下面是排版和文件目录。

代码部分是通过余数去确认停的位置，boxlist通过unity拖拉加入数据，chooseBoxList直接通过余数判断添加。
代码量很少，稍微看下就明白了。

直接上代码了：

using System;
using System.Collections;
using System.Collections.Generic;
using DG.Tweening;
using UnityEngine;

public class goLuckyDraw : MonoBehaviour
{
  private int index = 23;
  //index%12 来判断停在哪个位置
 // Use this for initialization
  private UISprite prize1,prize2,prize3,prize4,prize5,prize6,prize7,prize8,prize9,prize10,prize11,prize12, prize13, prize14;
  private UISprite transparentBox;
  public List<Transform> boxList = new List<Transform>();
  public List<Transform> chooseBoxList = new List<Transform>();
  void Start () {
    prize1 = GameObject.Find("Lucky/Bg/prize1").GetComponent<UISprite>();
    prize2 = GameObject.Find("Lucky/Bg/prize2").GetComponent<UISprite>();
    prize3 = GameObject.Find("Lucky/Bg/prize3").GetComponent<UISprite>();
    prize4 = Gam【本文由：香港云服务器http://www.558cloud.com提供，感谢】eObject.Find("Lucky/Bg/prize4").GetComponent<UISprite>();
    prize5 = GameObject.Find("Lucky/Bg/prize5").GetComponent<UISprite>();
    prize6 = GameObject.Find("Lucky/Bg/prize6").GetComponent<UISprite>();
    prize7 = GameObject.Find("Lucky/Bg/prize7").GetComponent<UISprite>();
    prize8 = GameObject.Find("Lucky/Bg/prize8").GetComponent<UISprite>();
    prize9 = GameObject.Find("Lucky/Bg/prize9").GetComponent<UISprite>();
    prize10 = GameObject.Find("Lucky/Bg/prize10").GetComponent<UISprite>();
    prize11 = GameObject.Find("Lucky/Bg/prize11").GetComponent<UISprite>();
    prize12 = GameObject.Find("Lucky/Bg/prize12").GetComponent<UISprite>();
    prize13 = GameObject.Find("Lucky/Bg/prize13").GetComponent<UISprite>();
    prize14 = GameObject.Find("Lucky/Bg/prize14").GetComponent<UISprite>();
    transparentBox = GameObject.Find("Bg/Transparentbox").GetComponent<UISprite>();
    transparentBox.gameObject.SetActive(false);
    //获取需要监听的按钮对象
    GameObject button = GameObject.Find("Lucky/Bg/start");
    //设置这个按钮的监听，指向本类的ButtonClick方法中。
    UIEventListener.Get(button).onClick = StartLuckyDraw;

    chooseIndex(index);

    // StartLuckyDraw();
   
  }

  IEnumerator Move( )
  {
    float time;
    
    for (int i = 0; i < boxList.Count; i++)
    {
      time = Mathf.Lerp(0.04f, 0.05f, 0.05f*i);
      Debug.Log("---time----="+time);
      transparentBox.transform.DOLocalMove(boxList[i].localPosition, time);
      yield return new WaitForSeconds(0.05f);
    }
    for (int i = 0; i < boxList.Count; i++)
    {
      time = Mathf.Lerp(0.05f, 0.065f, 0.05f * i);
      Debug.Log("---time3----=" + time);
      transparentBox.transform.DOLocalMove(boxList[i].localPosition, time);
      yield return new WaitForSeconds(0.05f);
    }
    for (int i = 0; i < boxList.Count; i++)
    {
      time = Mathf.Lerp(0.065f, 0.08f, 0.05f * i);
      Debug.Log("---time2----=" + time);
      transparentBox.transform.DOLocalMove(boxList[i].localPosition, time);
      yield return new WaitForSeconds(0.05f);
    }
    for (int i = 0; i < chooseBoxList.Count; i++)
    {
      transparentBox.transform.DOLocalMove(chooseBoxList[i].localPosition,0.1f);
      yield return new WaitForSeconds(0.1f);
    }
    yield return new WaitForSeconds(2f);
    transparentBox.gameObject.SetActive(false);
  }

  private void chooseIndex(int index)
  {
    chooseBoxList.Clear();
    for (int i = 0; i < index % 12; i++)
    {
      chooseBoxList.Add(boxList[i]);
    }
  }

  private void StartLuckyDraw(GameObject go)
  {
    transparentBox.gameObject.SetActive(true);
    StartCoroutine(Move());
  }

  void Update () {
 
 }
}

代码很糙，大家自己完善吧！
