The number of children the parent Transform has.
Note: The parent is not included in the count.
using UnityEngine;
public class ExampleClass : MonoBehaviour { // generate a group of connected GameObjects void Awake() { GameObject go = new GameObject("top");
Random.InitState(System.Environment.TickCount);
// add 3, 4 or 5 "middle" children that report to "top" for (int i = 0; i < Random.Range(3, 6); i++) { GameObject go2 = new GameObject("middle" + i.ToString()); go2.transform.parent = go.transform;
// add between 1 to 8 "bottom" children that report to the above "middle" for (int j = 0; j < Random.Range(1, 8); j++) { GameObject go3 = new GameObject("bottom" + j); go3.transform.parent = go2.transform; } } }
void Start() { // how many children does top have? GameObject go = GameObject.Find("top"); Debug.Log(go.name + " has " + go.transform.childCount + " children");
// pick a random middle group and pick a member of its children go = GameObject.Find("middle" + Random.Range(0, go.transform.childCount)); Debug.Log(go.name + " has " + go.transform.childCount + " children"); } }
