LoadScene场景异步加载

using UnityEngine;

using System.Collections;

using UnityEngine.SceneManagement;

using UnityEngine.UI;

public class LoadScene: MonoBehaviour

{

public Slider Slider;//定义滑动条

private AsyncOperation async;

private int number = 0;

private int num = 0;

private void Start()

{

//赋初始值

Slider.value = 0;

//开启协程

StartCoroutine("start");

}

void Update()

{

//滑动条的移动

Slider.value = number / 100f;

}

//协程

private IEnumerator start()

{

//要加载的大场景Scene

async = SceneManager.LoadSceneAsync("Scene");

//初始加载场景不激活

async.allowSceneActivation = false;

//增加滑动平滑性

while (async.progress < 0.9f)

{

//加载进度

num = (int)async.progress * 100;

while (number < num)

{

++number;

//等待时长

yield return new WaitForSeconds(0);

}

}

num = 100;

//增加平滑效果

while (number < num)

{

++number;

//等待时长

yield return new WaitForSeconds(0);

}

//加载场景激活

async.allowSceneActivation = true;

}

}

注：加载的场景Scene需要要将场景添加到构建设置，请使用菜单File-> Build Settings ...之后才可使用.......
