UI几个重要使用方法

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class ApplicationDemo : MonoBehaviour {

    void Start()
    {
        //支持后台运行
        Application.runInBackground = true;
        //当前工程的Assets文件夹路径
        Debug.Log (Application.dataPath);
        //持久化路径
        Debug.Log (Application.persistentDataPath);
        //截屏
//        Application.CaptureScreenshot ("Assets/ABC.jpg");
        //打开网页
//        Application.OpenURL ("http://www.baidu.com");
    }

    void Update()
    {
        if (Input.GetMouseButtonDown ()) {
            //切换场景
//            SceneManager.LoadScene ("EasyTouch");
            AsyncOperation ao = SceneManager.LoadSceneAsync("EasyTouch");
//            ao.progress-->异步加载的百分比
        }
    }
