初投稿。気が向いた時にネタあげていきます。

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;
    }
}
