Question by perdanny · Nov 07, 2012 at 09:09 PM · yielddelay

Delay my Scene for few seconds, not sure what wrong

using UnityEngine; using System.Collections;

public class GameManager : MonoBehaviour { public GameObject asteroidsGenerator; public GUIText guiTextScore; public int timeInterval = 1; public float delayTime = 2f; float time; int totalTime; void Start () { Instantiate(asteroidsGenerator, Vector3.zero, Quaternion.identity); time = 0f; totalTime = 0; } void Update () { time += Time.deltaTime; if(AsteroidsGenerator.isActive) { if(time >= timeInterval) { totalTime += timeInterval; guiTextScore.text = "X " + totalTime.ToString(); time = 0f; } } else GameOver(); } IEnumerator GameOver() { guiTextScore.text = "Your Total Score Is:" + totalTime.ToString(); yield return StartCoroutine(MyDelayMethod(delayTime)); Application.LoadLevel(2); } IEnumerator MyDelayMethod(float delay) { yield return new WaitForSeconds(delay); } }

Well this my code, not sure what im doing wrong, is there any other way to implement the delay?

You need to call GameOver with StartCoroutine, just like MyDelayMethod, or the yield won't do anything.

And, please, format your code.

You should not call GameOver directly, as @FakeBerenger said: use StartCoroutine(GameOver) instead. But there's another problem: if you use StartCoroutine inside Update, a new GameOver coroutine will be started each frame, crowding the memory with GameOver instances running in parallel.
In order to avoid this, use a simple boolean flag to ensure that GameOver is started only once:

   ...
   int totalTime;
   bool gameOver = false; // boolean flag
   
   ...
   void Update ()
   {
     time += Time.deltaTime;
     if(AsteroidsGenerator.isActive)
     {
       ...
     }
     else 
     if (!gameOver){ // only start GameOver once
       StartCoroutine(GameOver());
       gameOver = true; // no more GameOver calls
     }
   }
