unity避头点,避开行前标点符号

using System.Collections.Generic;

using UnityEngine;
using UnityEngine.UI;
public class AvoidPunctuation : Text{    
//避头点,每行第一一个文字不出现标点,继承Text    
public string CullList = @"！|？|，|。|《|》|）|：|“|”|‘|’|、|；|+|-";    
public IList<UILineInfo> lineInfos;    
public StringBuilder stringBuilder;    
public override void SetVerticesDirty()    {        
base.SetVerticesDirty();        
stringBuilder = new StringBuilder(text);        
lineInfos = cachedTextGenerator.lines;
if (text.Length<=0)return;        
foreach (var i in lineInfos)        {            
bool isMach = Regex.IsMatch(text[i.startCharIdx].ToString(), CullList);            
if (isMach)            {                
if (i.startCharIdx <= 0)                    
continue;                
stringBuilder.Insert(i.startCharIdx - 1, "*****");            }        }        
 = stringBuilder.ToString();}} 

UGUI采用脏标记系统，只要控件被标记为“脏”状态，就会强制刷新一遍，在每次改变了顶点或者纹理后，调用SetVerticesDirty() 或 SetMaterialDirty()即可
