Prevent A Spawned Object From Scaling

I have objects that spawn in via script in empty GameObjects. The script sets a spheroid (The World) as the parent of the newly spawned in objects. The world is a big stretched sphere. The objects seem to be following suit, stretching out as well. Is there a way to prevent this. Here is my script on each empty GameObject that spawns stuff:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class BackgroundSpawner : MonoBehaviour
6. {
7.     //A list of prefabs to choose from. Consist of the object with the death collider and pass collider which awards points.
8.     public GameObject[] prefabs;
9.  
10.     public void Spawn()
11.     {
12.         Vector3 vec = new Vector3(transform.position.x, transform.position.y, transform.position.z);
13.         //GameObject choice = prefabs[Random.Range(0, 5)];
14.         GameObject prefab = Instantiate(prefabs[Random.Range(0, 5)], vec, transform.rotation, transform.parent);
15.         //prefab.transform.localScale = choice.transform.localScale;
16.        
17.         Ray down = new Ray(transform.position, -Vector3.up);
18.         RaycastHit hit;
19.         if (Physics.Raycast(down, out hit))
20.         {
21.             prefab.transform.RotateAround(transform.position, transform.up, Random.Range(0.0f, 360.0f));
22.             prefab.transform.position = prefab.transform.position - new Vector3(0.0f, hit.distance, 0.0f);
23.         }
24.     }
25. }
26.  

 

The scaling is probably happening due to the fourth "parent" argument to Instantiate in line 14 above.

Prove / disprove that theory, and if it holds, try removing the argument, then do the parenting yourself with .SetParent(), using an appropriate true / false for the second optional argument to SetParent(). See docs.

 

Works, appreciate that!

 

Hi I'm sorry, false alarm it's still stretching, it just so happened it spawned in the thinner trees so it did not look stretched. Any suggestions?

 

Try spawning it first without a parent and then do transform.parent = bigStretchedSphereTransform.
It should do.

 

Here is my new code I can't seem to figure it out.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Spawner : MonoBehaviour
6. {
7.     //A list of prefabs to choose from. Consist of the object with the death collider and pass collider which awards points.
8.     public GameObject[] prefabs;
9.     public GameObject earth;
10.  
11.     public void Spawn()
12.     {
13.         Vector3 vec = new Vector3(transform.position.x, transform.position.y, transform.position.z);
14.         GameObject prefab = Instantiate(prefabs[Random.Range(0, prefabs.Length)], vec, transform.rotation);
15.         prefab.transform.SetParent(earth.transform, true);
16.         Ray down = new Ray(transform.position, -Vector3.up);
17.         RaycastHit hit;
18.         if (Physics.Raycast(down, out hit))
19.         {
20.             transform.Rotate(new Vector3(0.0f, Random.Range(0.0f,360.0f), 0.0f));
21.             prefab.transform.position = prefab.transform.position - new Vector3(0.0f, hit.distance, 0.0f);
22.         }
23.     }
24. }
25.  

 

Your issue is that you have a parent object that is not scaled uniformly.

Rule of thumb is that any object that has children should have uniform scaling, else you will deal with stretching/skewing issues like this. To fix it, refactor your hierarchy such that the parent object is not scaled. You can move any renderers/colliders etc that need to be scaled to a separate child/sibling GameObject instead.
