unity get child data - class

Question

I am trying to create a procedural created dungeon in Unity.
I have it creating the dungeon, and have a script attached to each prefab that goes to make up the walls, floor etc. Each one of these is attached to a single parent, to make it easy to delete and rebuild the entire dungeon. The script contains details:
public class WallPrefab
{
public bool use;
private int roomId;
public WallTypes type; //enum = torch, switch, item etc
public WallDirections direction; //direction wall is facing
public GameObject myPrefab; //nested
}
The prefab also contains an empty game object used as a mount point for torches, switches etc.
myPrefab
prefab //prefab for the actual 3d object
wallmount //empty game object to store location and rotation details
....
My questions:
1. How do I get the wall type?
int childs = transform.childCount;
for (var i = childs - 1; i >= 0; i--)
{
c = transform.GetChild(i).gameObject;
Debug.Log("child:" + c.name);
//WallTypes g = c.GetComponentInChildren<WallPrefab>().type;
WallTypes g = c.transform.GetComponentInChildren<WallSettings>().type;
(Edited to insert working solution to this part of my problem!)
This code does not work, because Unity complains that:
ArgumentException: GetComponent requires that the requested component
'WallPrefab' derives from MonoBehaviour or Component or is an
interface.
How do I get the transform of the mount point?
I know how to get the location and rotation, once I get the mount point, but how do I actually get the mount point?

Answer 1

Question 1 seems pretty self explainatory.
Question 2 looks a bit more interessting.
If i understood you correctly, you have a script, that "creates" torches on specified mount points. Assuming those mount points are empty game objects and you dont want to add torches directly into the prefab (would be nice if we got a little bit more detail here on how exactly your dungeon+mount point is generated), i would add a script to the prefab, add a GameObject instance variable and use the inspector to drag the mount point onto the script. then i would use "gameobjectVariable.transform.position" to get the position.
something like:
public class prefabClassWithMountPoints{
GameObject mountpoint; //drag mount point from inspector
GameObject torchGameObject; //drag torch prefab here
public void createTorch(){
GameObject torchObject = Instantiate(torchGameObject, mountpoint.transform.position, Quaternion.identity);
//...
}
//rest of code
}
this is assuming the mount points are not randomly generated WITHIN the prefab.
