本文介绍了一个使用Unity3D进行窗口管理的缓冲池实现。通过单例类UIWindowManager，实现了窗口对象的创建与销毁。当打开窗口时，首先检查缓冲池中是否存在该窗口，如果存在则关闭并复用，否则从Resources加载并实例化。关闭窗口时，将对象销毁并从缓冲池移除。

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

/**
	* 单例类，创建或者销毁窗体
	 */
public class UIWindowManager {
	
	private static UIWindowManager windowMag;
	private static Dictionary<string, GameObject> windowCache = new Dictionary<string, GameObject>();
	
	public static UIWindowManager GetInstance() {
		if (windowMag == null) {
			windowMag = new UIWindowManager();
		}
		return windowMag;
	}
	
	public GameObject OpenWindow(string windowName) {
		if (windowCache.ContainsKey(windowName)) {
			CloseWindow(windowName);
			return null;
		}
		GameObject windowObject = Resources.Load(windowName) as GameObject;
		GameObject prefabClone = GameObject.Instantiate(windowObject);
		
		prefabClone.transform.parent = UIRoot.list[0].transform;
		prefabClone.transform.localPosition = Vector3.zero;
		prefabClone.transform.localScale = Vector3.one;
		windowCache.Add(windowName, prefabClone);
		return prefabClone;
	}
	public void CloseWindow(string windowName) {
		if (windowCache.ContainsKey(windowName)) {
//			Debug.Log(windowName);
			GameObject.Destroy(windowCache[windowName]);
			windowCache.Remove(windowName);
		}
	}
