WaitWhile

Description

暂停协程执行，直到提供的委托评估为 /false/。

在协程中，WaitWhile 只能与 yield 语句结合使用。

每帧都会执行提供的委托，在脚本 MonoBehaviour.Update 之后 MonoBehaviour.LateUpdate 之前执行。当委托最终评估为 false 时，协程将继续其执行。

using UnityEngine;
using System.Collections;

public class WaitWhileExample : MonoBehaviour
{
    public int frame;

    void Start()
    {
        StartCoroutine(Example());
    }

    IEnumerator Example()
    {
        Debug.Log("Waiting for prince/princess to rescue me...");
        yield return new WaitWhile(() => frame < 10);
        Debug.Log("Finally I have been rescued!");
    }

    void Update()
    {
        if (frame <= 10)
        {
            Debug.Log("Frame: " + frame);
            frame++;
        }
    }
}
