Changing LocalScale in code affecting prefab stored in Assets

Questions & Answers

As a part of some basic code I’m writing, I make a copy of a prefab as a member of a list. I then edit the localScale of the object in the list. When I do this however, the scale of the object changes in my assets windows and persists after the game stops running. Here is my code:

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class CreatePlatforms : MonoBehaviour 
{
	public GameObject platformPrefab;
	private int numToMake;
	private List<GameObject> platforms = new List<GameObject>();

	// Use this for initialization
	void Start () 
	{
		numToMake = 2;
		Create();
	}
	
	// Update is called once per frame
	void Update () 
	{
	
	}

	void Create()
	{
		for(int i = 0; i < numToMake; i++)
		{
			platforms.Add(platformPrefab);
			platforms*.transform.localScale /= numToMake;*

Instantiate(platforms_, new Vector3(1.2f + numToMake1.2f, .85f + numToMake.85f, 0), Quaternion.identity);_
* }*
* }*
}

The “platformPrefab” is attached to my script through the editor.
I also realize the math on my Instantiate command won’t do what I want for a variety of reasons, but the localScale problem is more an issue to me at the moment.

You are actually changing the scale of the prefab in the project window.
To only change the scale of the GameObject you have just Instantiated you can do this:

void Create()
{
     for(int i = 0; i < numToMake; i++)
     {
         platforms.Add(platformPrefab);
         GameObject platform = (GameObject)Instantiate(platforms_, new Vector3(1.2f + numToMake*1.2f, .85f + numToMake*.85f, 0), Quaternion.identity); // You have have to cast it to a GameObject_

platform.transform.localScale /= numToMake;
}
}
So now you only effect the GameObject you have just Instantiated.
