用NGUI写了个虚拟按钮，能用，但很卡，求救啊！
本帖最后由 luckytjm 于 2013-9-11 23:40 编辑先说一下具体情况，然后再上代码吧，首先呢，按钮是NGUI做的，然后把原先Box Collider换成Sphere Collider，建了一个新的背景图文集，最后再添加了我写的这串代码就没了，请各路大神帮忙研究一下哈，到底卡在哪个地方了哈。对了，还有就是我的分辨率是517*291哈，下面是上代码:using UnityEngine;
using System.Collections;

private float currentDistance; //note 单签摇杆圆心离初始圆心的距离 note
