本文介绍了一款Unity中使用的简单打字效果脚本，它能够使UILabel的内容逐渐填充显示，模仿真实的打字过程。该脚本支持自定义每秒显示字符数，并可播放打字声音效果。

using UnityEngine;

/// <summary>
/// Trivial script that fills the label's contents gradually, as if someone was typing.
/// </summary>

[RequireComponent(typeof(UILabel))]
[AddComponentMenu("NGUI/Examples/Typewriter Effect")]
public class TypewriterEffect : MonoBehaviour
{
	public int charsPerSecond = 40;
	public AudioClip typeSound;
	UILabel mLabel;
	string mText;
	int mOffset = 0;
	float mNextChar = 0f;
	
	void OnEnable(){
		mLabel = GetComponent<UILabel>();
		mLabel.enabled = false;
		mLabel = null;
	}
	
 	void Start(){
		
	}
	
	public void FinishTypewriter(){
		mLabel.text  = mText;					
		Destroy(this);
	}
	
	
	
	void Update ()
	{
		if (mLabel == null)
		{		
			mLabel = GetComponent<UILabel>();
			//mLabel.supportEncoding = false;
			mLabel.enabled = true;
			mLabel.symbolStyle = UIFont.SymbolStyle.None;
			mText = mLabel.font.WrapText(mLabel.text, mLabel.lineWidth / mLabel.cachedTransform.localScale.x, mLabel.maxLineCount, true, UIFont.SymbolStyle.None);
		}

		if (mOffset < mText.Length)
		{
			if (mNextChar <= Time.time)
			{
				charsPerSecond = Mathf.Max(1, charsPerSecond);
				// Periods and end-of-line characters should pause for a longer time.
				float delay = 1f / charsPerSecond;
				char c = mText[mOffset];
				if (c == '.' || c == ',' || c == '!' || c == '?' || c == ' ') delay *= 4f;
				else if (c == '。' || c == '？' || c == '！' || c == '，' ) delay *= 4f;
				string s = mText.Substring(0, ++mOffset);
				if(c == '['){
					for(int i = 0;i< 20; i++){
							s = mText.Substring(0, ++mOffset);
							int index2 = s.IndexOf(']',mOffset - 1);
							if(index2 != -1 ){
								break;
							}
						}
				}
				else if(c == '\\'){
						s = mText.Substring(0, ++mOffset);
				}
				mLabel.text  = s;					
				if(typeSound != null){
					AudioManage.Instance.PlayOneShot(typeSound);
