本萌新最近想用UNITY做个游戏

可是好难啊,,,

有没有大佬教教我异步

比如异步加载

和AutoResetEvent

 

 

 

 

 

 

 

 

 

 

class Program
    {

        static void Main()
        {
            Request req = new Request();

            //这个人去干三件大事  
            Thread GetCarThread = new Thread(new ThreadStart(req.InterfaceA));
            GetCarThread.Start();

            Thread GetHouseThead = new Thread(new ThreadStart(req.InterfaceB));
            GetHouseThead.Start();

            //等待三件事都干成的喜讯通知信息  
            AutoResetEvent.WaitAll(req.autoEvents);

            //这个人就开心了。  
            req.InterfaceC();

            System.Console.ReadKey();
        }
    }

    public class Request
    {
        //建立事件数组  
        public AutoResetEvent[] autoEvents = null;

        public Request()
        {
            autoEvents = new AutoResetEvent[]
            {
                new AutoResetEvent(false),
                new AutoResetEvent(false)
            };
        }

        public void InterfaceA()
        {
            System.Console.WriteLine("请求A接口");

            Thread.Sleep(1000*2);

            autoEvents[0].Set();

            System.Console.WriteLine("A接口完成");
        }

        public void InterfaceB()
        {
            System.Console.WriteLine("请求B接口");

            Thread.Sleep(1000 * 1);

            autoEvents[1].Set();

            System.Console.WriteLine("B接口完成");
        }

        public void InterfaceC()
        {
            System.Console.WriteLine("两个接口都已经请求完，正在处理C");
        }
    }

 

public class AsyncLoadScene : MonoBehaviour

{

public Slider loadingSlider;

public Text loadingText;

private float loadingSpeed = 1;

private float targetValue;

private AsyncOperation operation;

// Use this for initialization

void Start ()

{

loadingSlider.value = 0.0f;

if (SceneManager.GetActiveScene().name == "Loading")

{

//启动协程

StartCoroutine(AsyncLoading());

}

}

IEnumerator AsyncLoading()

{

operation = SceneManager.LoadSceneAsync(Globe.nextSceneName);

//阻止当加载完成自动切换

operation.allowSceneActivation = false;

yield return operation;

}

// Update is called once per frame

void Update ()

{

targetValue = operation.progress;

if (operation.progress >= 0.9f)

{

//operation.progress的值最大为0.9

targetValue = 1.0f;

}

if (targetValue != loadingSlider.value)

{

//插值运算

loadingSlider.value = Mathf.Lerp(loadingSlider.value, targetValue, Time.deltaTime * loadingSpeed);

if (Mathf.Abs(loadingSlider.value - targetValue) < 0.01f)

{

loadingSlider.value = targetValue;

}

}

loadingText.text = ((int)(loadingSlider.value * 100)).ToString() + "%";

if ((int)(loadingSlider.value * 100) == 100)

{

//允许异步加载完毕后自动切换场景

operation.allowSceneActivation = true;

}
