WaitUntil(Func<bool>)
Initializes a yield instruction with a given delegate to be evaluated.
public WaitUntil(Func<bool> predicate)
Parameters
Supplied delegate will be evaluated each frame after MonoBehaviour.Update() and before MonoBehaviour.LateUpdate() until delegate returns true.
WaitUntil(Func<bool>, TimeSpan, Action, WaitTimeoutMode)
Initializes a yield instruction with a given delegate to be evaluated.
public WaitUntil(Func<bool> predicate, TimeSpan timeout, Action onTimeout, WaitTimeoutMode timeoutMode = WaitTimeoutMode.Realtime)
Parameters
Supplied delegate will be evaluated each frame after MonoBehaviour.Update() and before MonoBehaviour.LateUpdate() until delegate returns true.
Maximum time to wait after creation of the instance for the predicate to return true.
The action to perform when the timeout is reached. Only performed if the predicate fails to return true before the maximum time specified.
Mode in which to measure time to determine timeout. Real time by default. Can be set to in-game time, which is scaled according to the value of Time.timeScale.
Examples
using UnityEngine;using System;using System.Collections;public class WaitUntilExample : MonoBehaviour{ public bool buttonPressed; void Start() { StartCoroutine(Example()); } IEnumerator Example() { Debug.Log("Waiting for button to be pressed..."); yield return new WaitUntil(() => buttonPressed, TimeSpan.FromSeconds(3), () => Debug.Log("button was not pressed in time!")); }}
