how to arrangement child objects using c#

i have a gameobject that have a group of plane meshes that created randomly as child every one of this planes have a "2f" offset in x axis between every plane

what i wanna do is i wanna make the parent object arrangement the child objects on rows and columns even if one of this child deleted during the game or added so if i have 8 planes mesh it should look like that 2 rows and 4 columns like that but i don't know how to do that ?





i know how to get child objects and making offset but i do't know how to get the format like that in the image i wanna to arrangement the planes meshes that i can acces from this for loop

Code (CSharp):

1.  void Update(){
2.           Transform[] children = new Transform[transform.childCount];
3.                  //Debug.Log(transform.childCount);
4.                      for (int i=0; i<transform.childCount; i++) {
5.                          children[i]=transform.GetChild(i);
6.                            
7.                      }
8.       }

 

First of all, you are generating a new Transform array every frame! Thats not a good idea to do. So you want to offset x and y axis, right? So, if your x-axis gos through the max offset of 2*4 = 8, it should offset to y, right? You also want to use List<> instead of that array and add them on start, so you can delete them on runtime and check for the count etc.

 

thanks for your reply yes right so i should make something like that transform.childCount * 2 /4 to get the columns numbers then the columns numbers * 2 to get the y axis offset value that what you mean ?

are my list part better now ?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Coulmnandrowsformating : MonoBehaviour {
6.  
7.  
8.     private GameObject[] children;
9.  
10.     // Use this for initialization
11.     void Start () {
12.      
13.              
14.  
15.     }
16.  
17.     // Update is called once per frame
18.     void Update () {
19.  
20.                      //Transform[] children = new Transform[transform.childCount];
21.                     Debug.Log(transform.childCount);
22.                     children = new GameObject[transform.childCount];
23.                     for (int i=0; i<transform.childCount; i++) {
24.                         children[i]=transform.GetChild(i).gameObject;
25.  
26.                     }
27.  
28.  
29.  
30.     }
31. }

 

You dont need it in update. Just put in in a coroutine and run it whenever the pile number changes. Thats what i was talking about. then you can check if the i is > 4, if it is, offset the y value of your transforms and put the x value back to the first value.
