Scripting - Disabling Specific Child of Object

Unity Engine
1

Hi all,
I am trying to set up a script that will enable a specific child of an object when a raycast hits it, and disable it when it doesn’t hit it. I’ve tried everything and haven’t found a solution for what I’m looking for. I found the ActiveRecursive method, but all I’ve been able to do with that is deactivate al the children and the parent, and then reactivate the parent. I’d also like to know how to access certain parts of the child, such as a particle emitter’s emit property. I’ve only been scripting for a few days, so bear with me. This is what I’ve got so far:

var rayHit : RaycastHit;
var delayTime : float = 0;

function FixedUpdate () {
	var delayAmount : float = .2;
	
	if (Time.time > delayTime) {
		var fwd = transform.TransformDirection(Vector3.forward);
	
		Screen.lockCursor = true;
		
		Debug.DrawRay (transform.position, transform.TransformDirection(Vector3.forward) * 5, Color.white);
		
		if (Physics.Raycast(transform.position, fwd, rayHit, 5)) {
			//if () {
				rayHit.collider.gameOnject.GetChild("Sphere").active = false;
			//} 

			
			//Debug.Log(rayHit.name);
			//Debug.Log(rayHit.gameOnject.GetChild("Sphere").name);
		}
	
	delayTime = Time.time + delayAmount;
	
	//Debug.Log(Time.time + "   " + delayTime);
	}
}

So I’ve got a variable (delayTime and delayAmount) that will make the function update every 0.2 seconds, I’ve got a ray cast shooting a ray 5 units ahead of me, and i’d like to have an if statement along the lines of:

if the ray hits and object that has a child named “outline”, then activate the object (or it’s mesh render)
else, then deactivate the object.

Any help would be greatly appreciated, thanks in advance!

I’ve got a workaround going that will work for my project, but it isn’t truly what I’d like to do. It will find objects with the same Name and Tag, but it doesn’t reference the children of the object itself. This means it will only work with objects that don’t have duplicate names. If my prefabs all have the same name, this won’t work, any ideas?

var collisionObject : GameObject;
var collisionObjecthold : GameObject = null;
var rayHit : RaycastHit;
var delayTime : float = 0;

function FixedUpdate () {
	var delayAmount : float = 0.1;
	
	if (Time.time > delayTime) {
		var fwd = transform.TransformDirection(Vector3.forward);
	
		Screen.lockCursor = true;
		
		Debug.DrawRay (transform.position, fwd * 5, Color.white);
			
		if (Physics.Raycast(transform.position, fwd, rayHit, 5)) {
			collisionObject = GameObject.Find((rayHit.collider.gameObject.name) + " outline");
			
			//Debug.Log(rayHit.gameOnject.GetChild("Cube outline").name);
		}
		else {
			collisionObject = null;
		}
		
		delayTime = Time.time + delayAmount;
		
		//Debug.Log(Time.time + "   " + delayTime);
	}
		
	if (collisionObject != null) {
		collisionObject.GetComponent(MeshRenderer).enabled = false;
		collisionObjecthold = collisionObject;
	}
	else {
		collisionObjecthold.GetComponent(MeshRenderer).enabled = true;
	}
}
