Destroying all child objects.

Questions & Answers
1

When attempting to destroy an instance of a game object that has multiple child objects, the object remains visible on the screen unless I do the following:

private void ScheduleForDesruction(Rigidbody gameObject, float time)
{
    foreach(Transform  xform in gameObject.transform)
    {
        Destroy(xform.gameObject, time);
    }           
    Destroy(gameObject, time);      
}

Even then, there is an audio source gizmo that remains visible on the Scene view screen. Everything I've found here in the wiki regarding this indicates that calling Destroy on a game object effectively destroys all the children. This doesn't happen in my case. In fact, if I don't iterate through the entire transform array as above, the object remains visible on the screen.

Is there something I need to do differently here? Perhaps when the object is a Rigidbody, Destroying it requires different treatment? ... or when there's an audio source attached, does it have to be deleted individually?

Destroy(gameObject, time); in your script destroys only the component Rigidbody not the game object itself (because your variable gameObject is of type Rigidbody).

Courtesy of Zerot on the IRC channel:

0,1,2,3,4

loop: index = 0 : ->0,1,2,3,4 Destroy:
contents shift: ->1,2,3,4 index++
because of loop: 1,->2,3,4 index = 1
Destroy: contents shift: 1,->3,4
index++

separate array/list loop: index = 0 :
->0,1,2,3,4 Destroy: no content shift because of separate array: ->0,1,2,3,4
index++ because of loop: 0,->1,2,3,4
index = 1 Destroy: no content shift
because of separate array: 0,->1,2,3,4

Basically you can’t remove elements while inside a fast enumeration, otherwise it will miss alternate elements.
