Question by cadeautje · Sep 30, 2015 at 01:01 PM · c#random.rangelocalscale

how to scale an object on instantiate with a random value

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.

But if I do that they wont have the same random value, x might be 1 while y could 5 I need the xyz to get the same random value

So just use Random.Range once and apply that to them all.

Well, I honestly have no idea what you mean, but I made it work by simply making the X have a random value and making the Y and Z equal to the X
