class in UnityEngine
/
Inherits from:CustomYieldInstruction
/
Implemented in:UnityEngine.CoreModule
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++; } } }
