NGUIのUILabelを一文字ずつ書き出す

初投稿。気が向いた時にネタあげていきます。
主にコピペ用の簡単ハックを書く予定です。

NGUIのUILabelを一文字ずつ出力するサンプル

TextTest.cs

using UnityEngine;
using System;
using System.Collections;
using System.Text;
using System.Text.RegularExpressions;

public class TextTest : MonoBehaviour {

	void Start () {
		string text = "ほげ[FF0000]ほげ[-]ほげ";
		//string text = GetComponent<UILabel>().text;
		StartCoroutine(textWriter(text));
	}

	IEnumerator textWriter(string text){

		int len = 0;
		StringBuilder sb = new StringBuilder();
		UILabel label = GetComponent<UILabel>();
		label.text = sb.ToString();
		
		Regex r = new Regex(@"^\[[0-9A-F]{6}\]$");

		yield return null;

		while(len < text.Length){
			// Font Colorの評価
			string txt = text.Substring( len , 1 );
			if (txt == "["){
				if (len+3 < text.Length){
					txt = text.Substring( len , 3 );
					if (txt == "[-]"){
						sb.Append( txt );
						len += 3;
					} else if (len+8 < text.Length){
						txt = text.Substring( len , 8 );
						if (r.IsMatch(txt)){
							sb.Append( txt );
							len += 8;
						}	
					}
				}
				if (len >= text.Length) break;
			}
			sb.Append( text.Substring( len , 1 ) );
			label.text = sb.ToString();
			len++;
			//Debug.Log(len);
			yield return null;
		}
		yield return null;
	}
}
