Coroutines?

Code (JavaScript):

1. var triggered = false;
2. function Update()
3. {
4.     if(triggered == true)
5.     {
6.         StartCoroutine(WaitCoroutine(1));
7.     }
8.     if (distance <= 3)
9.     {
10.         sanityGUI.currentSanity = sanityGUI.currentSanity + sanityDamage.scarePercent;
11.         triggered = true;
12.         AudioSource.PlayClipAtPoint(ScareSound, enemy.position);
13.     }
14. }

I want to make a proper coroutine, but I can't figure out how. Can anyone help me here?

 

Well, I'm not sure what you're attempting.

Update isn't a coroutine, so there's that issue.

Check out the docs, then come back with a more specific question:
