Make a suboject visible using C#

I am trying to modify a C# script so that a subobject becomes visible upon a collision event. Below is how the object looks in the hierarchy:

-EnemyEasy (contains collider, rigid body, C# script)

– Enemy (Contains various subobjects, I want this visible all of the time)

– EnemyWithCoins (Contains various subobjects, I want this to become visible when the Root object’s collider comes in contact with another collider)

Any help is greatly appreciated.

I not completely sure of how you have things setup, but here is a script that when the parent receives a collision, the children are made visible:

#pragma strict

function OnCollisionEnter() {
	var renderers = transform.GetComponentsInChildren(Renderer);
	for (var rend : Renderer in renderers) {
		rend.enabled = true;
	}
}

Also note you may want to remove or disable the colliders on the sub-objects depending on your use. Even though the renderers are disabled, the colliders will still be active unless you remove or disable them. Also note that ‘GetComponentsInChildren()’ is a bit misnamed since it also returns the parent you used in calling the function.
