Waiting in Unity 3D game engine in C#?

Question

Is there a command in Unity 3D game engine with C# to make the code wait before something happens? Here is an example:

void Start () {
    //(wait code here)
    Connect();
}

Answer 1

The promoted way of doing this with the Unity3D Game Engine tutorials is with WaitForSeconds which waits for a given float value (such as 0.5f for half a second).

But with this rule you need to set the class to an IEnumerator so:

public flat StartWait;

IEnumerator SpawnWaves ()
    {
        //your code
        yield return new WaitForSeconds (StartWait);
    }

This causes the class/object to wait without freezing the whole game logic. See also http://unity3d.com/learn/tutorials/projects/space-shooter/spawning-waves
