测试代码：

using UnityEngine;using System.Collections;public class Test : MonoBehaviour{    void Start()    {        MouseResponseManager.Register(null, () =>        {            Debug.Log("click");        }, () => {            Debug.Log("double click");        });    }    void OnGUI()    {        GUI.Label(new Rect(15, 15, 300, 100), "在舞台上单击/双击查看输出！");    }}
