how to scale an object on instantiate with a random value

Questions & Answers

I am trying to spawn birds with a random scale which works but I can only scale the x y and z individual and not the xyz at the same time (with the same random value)

this is my script:

using UnityEngine;
using System.Collections;

public class BirdScript : MonoBehaviour
{
public float wait;
public GameObject Bird;
public Vector3 spawnValues;

void Start () 
{
	StartCoroutine ( spawnBirds() );
}

IEnumerator spawnBirds()
{
	for(int i = 0 ; i < 2 ; i++)
	{
		Vector3 spawnPosition = new Vector3 (spawnValues.x ,Random.Range (8f, 25f) , spawnValues.z);
		Instantiate (Bird, spawnPosition , Quaternion.identity);
		Vector3 scale = Bird.transform.localScale;
		scale.x = Random.Range (1f, 5f);
		Bird.transform.localScale = scale;
		i = 0;
		yield return new WaitForSeconds (wait);
	}

}

}

any help would be greatly appreciated.

You need to scale the object you’re instantiating, not the prefab. Instantiate returns a reference to that object, so you assign it to a variable. In any case, simply assign the same value to x, y, and z.
