How to reference a parent object (i.e; from root or stage)?

I'm currently playing around with some AS3 platform gaming, and trying to go with a cleaner object-based approach for platforms. In short, I'm trying to detect if the player object is colliding with platform - ala:

if (!player.hitTestObject(this)) {
    //player falls
}

However, the problem is in actually referencing the player object - the player is at the following location (from the stage); manager.player - wheras the platforms are at manager.level.foreground.

Is there any way to actually reference the player object from within the foreground object as listed above, without passing in a constructor from the player to each and every instance of the platform?

You can get a static reference to the place that the player object is created in. In that class, you basically return a reference to the player.

you could do

if (!this.parent.parent.player.hitTestObject(this)) {
    //player falls
}

but i strongly advise against this as it is extremely inflexible to changes, and cause a possible debugging nightmare:)

would it not be neater to let the manager handle the collisions between it's children?
