WaitWhile

설명

Suspends the coroutine execution until the supplied delegate evaluates to false.

WaitWhile can only be used with a yield statement in coroutines.

The supplied delegate will be executed each frame after MonoBehaviour.Update and before MonoBehaviour.LateUpdate. When the delegate finally evaluates to false, the coroutine will proceed with its execution.

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++;
        }
    }
}
