Cache a lot of object transforms in a builtin array? (iPhone)

Question

I need to reset my player with pre-set position and orientation.

I have an arbitrary number of cube's (with correct orientation and positioning) around my level. I could like to check the player distance against all of them, and spawn him on the closest available point.

The question, is how can I get all of those objects into a built-in array in my Start() function? To simplify things, they are all a child of an object called SpawnPoints.

So, I need the blanks filled in here..

var spawnPoints : Transform[];

function Start() { // Find all the children's transforms of SpawnPoint (which could be about 30 or so, who knows) and put them into the array. }

function Spawn()
{
 // This bit I know how to do :)
 // Check distance
 // Spawn from the nearest and match orientation
}

There should be a way to do this with Generics in 3.0, but the syntax isn't documented (for JavaScript). In the meantime, put this in Start():

spawnPoints = new Transform[spawnPointParent.GetComponentsInChildren(Transform, true).Length - 1];
    var i = 0;
    for (var child in spawnPointParent) {
        transforms[i] = child;
        ++i;
    }

Ideally, you could do this outside of Start(); that is, run an Editor script and save the array before you build the game. Is that possible? It won't matter that it's not a great way of doing it, if you've got the horsepower of a Mac and as much time as you want to run the function.
