How to write a script for a gameObject that refers to all children?

Questions & Answers
1

HI!! I’m working on a project (a church) in Unity because I want to put it into the Dive. I’m trying to write a script for the parent (that is all my church exported from 3dSMax) that refers to every child (walls, windows, roofs…). I would like that clicking an object or better a child (a wall, a window…) a box appears with some information inside: how can I do this? Every child is a mesh collider in Unity and I have to work with Raycast and 3Dtext, because this project will be visible in the DIVE. I would be very happy if you could help me out with some information about this problem. Thanks a lot.

gameObject.GetComponentsInChildren(); //To get the scripts

//Or

List<gameObject> newList = new List<gameObject();

foreach (Transform child in Church) 
    newList.Add(child);

I hope i got it right

using UnityEngine;

public class ChurchChildrenInfoDisplay : MonoBehaviour {

	public ChildInformation[] childInformationArray;

	private void Start() {

		//usage example
		childInformationArray = new ChildInformation[] {

			new ChildInformation(GameObject.Find("Wall").transform, "This is a wall."),
			new ChildInformation(GameObject.Find("Window").transform, "This is a window.")
		};
	}

	private void Update () {
	
		if (Input.GetMouseButtonDown(0)) {

			Ray mouseRay = Camera.main.ScreenPointToRay(Input.mousePosition);
			RaycastHit hit;
			if (Physics.Raycast(mouseRay, out hit)) {

				Transform hitTransform = hit.transform;
				ChildInformation hitChildInfo = GetChildInformationOfTransform(hitTransform);
				if (hitChildInfo != null) {

					OnChildClicked(hitChildInfo);
				}
			}
		}
	}

	private ChildInformation GetChildInformationOfTransform(Transform child) {

		foreach (ChildInformation childInfo in childInformationArray) {

			if (childInfo.transform == child) {

				return childInfo;
			}
		}

		return null;
	}

	private void OnChildClicked(ChildInformation childInfo) {

		//display a box with some information inside
	}
}

[System.Serializable]
public class ChildInformation {

	public ChildInformation() {

	}

	public ChildInformation(Transform transform, string info) : this() {

		this.transform = transform;
		this.info = info;
	}

	public Transform transform;
	
	//this can be any (or several) datatype(s)
	public string info;
}
