Hello,

I try to write a script that can write in a text file all my structure for a scene.

Example :

[Name:FirstPersonController, Tag:Player]
–[Name:Camera, Tag:Undefined]
[Name:ZombieController, Tag:Zombies]
–[Name:ZombieHead, Tag:Undefined]
–[Name:ZombieArms, Tag:Undefined]

etc …

How can I achieve that ?

using UnityEngine;
using System.Collections;

public class HierarchyWriter : MonoBehaviour
{
    private void Start()
    {
        GameObject[] rootGameObjects = gameObject.scene.GetRootGameObjects();
        System.Text.StringBuilder stringBuilder = new System.Text.StringBuilder();

        for ( int gameObjectIndex = 0 ; gameObjectIndex < rootGameObjects.Length ; gameObjectIndex++ )
        {
            AppendGameObjectToString( rootGameObjects[gameObjectIndex], stringBuilder, 0 );
        }

        WriteIntoFile( stringBuilder.ToString() );


    }

    private void AppendGameObjectToString( GameObject gameObject, System.Text.StringBuilder stringBuilder, int level )
    {
        for ( int i = 0 ; i < level ; ++i )
            stringBuilder.Append( "--" );

        stringBuilder.Append( string.Format("[Name: {0}, Tag: {1}]

", gameObject.name, gameObject.tag ) );

        for( int childIndex = 0 ; childIndex < gameObject.transform.childCount ; ++childIndex )
        {
            AppendGameObjectToString( gameObject.transform.GetChild( childIndex ).gameObject, stringBuilder, level + 1 );
        }
    }

    private void WriteIntoFile( string fileContent )
    {
        // See
        // https://support.unity3d.com/hc/en-us/articles/115000341143-How-do-I-read-and-write-data-from-a-text-file-
        Debug.Log( fileContent ) ;
    }

}
