WaitWhile

Description

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 is executed each frame after MonoBehaviour.Update and before MonoBehaviour.LateUpdate. When the delegate evaluates to false, the coroutine resumes.

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++;
        }
    }
}
