Unity实现跑马灯抽奖效果

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 = GameObject.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！
