ts协程能支持吗 StartCoroutine

[995518790]

public* ResourcesAsync(path: string, callback: Function)
{
    UnityEngine.Debug.Log("ResourcesAsync start");
    var resourcesRequest: UnityEngine.ResourceRequest = UnityEngine.Resources.LoadAsync(path);
    yield resourcesRequest;
    UnityEngine.Debug.Log("ResourcesAsync end");
    var prefab = resourcesRequest.asset as UnityEngine.GameObject;
    callback(prefab);
}

    var rs = this.ResourcesAsync("Sphere", (prefab: UnityEngine.GameObject) => {
        UnityEngine.Object.Instantiate(prefab);
    });
    rs.next();
    rs.next();

这些在ts里面写，有时unity跑了就崩溃，而且rs.next();是同步加载资源，不是异步。CS里面StartCoroutine是异步。有没有ts里面写协程StartCoroutine... yield return... 的方法，求大佬帮忙

尽量使用async function实现功能(WWW/UnityWebRequest下载等), 使用Unity协程涉及大量的跨语言调用, 从性能考虑这不是一个好的选择

csharp代码

using System.Collections;
using Puerts;

public static class IEnumeratorUtil
{
    public static IEnumerator Generator(Func<object> next, Func<bool> isDone)
    {
        var done = false;
        while (!done)
        {
            yield return next();
            done = isDone();
        }
        next = null;
        isDone = null;
    }
    public static IEnumerator Generator(Func<Tick> next)
    {
        Tick tick = new Tick() { done = false };
        while (!tick.done)
        {
            tick = next();
            yield return tick.value;
        }
        next = null;
    }
    
    public static void UsingTick(this JsEnv jsEnv)
    {
        jsEnv.UsingFunc<Tick>();
    }
    public struct Tick
    {
        public bool done;
        public object value;
        public Tick(object value, bool done)
        {
            this.value = value;
            this.done = done;
        }
    }
}
