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！
