Finding a Collider's parent Game Object when using Physics.OverlapSphere

Hi all,
I am using Unity 2018.2.13f1
My script uses the Physics.OverlapSphere to find Colliders hitColliders. Then, I create a game object for the hitColliderObject. Here is my code.

Code (CSharp):

1. Collider[] hitColliders = Physics.OverlapSphere(center, explosionRadius);
2.  
3.         GameObject hitColliderObject = hitColliders.transform.parent.gameObject;

However, I am getting an error under hitColliders.transform.parent.gameObject; The error is:

Error CS1061: 'Collider[]' does not contain a definition for 'transform' and no extension method 'transform' accepting a first argument of type 'Collider[]' could be found (are you missing a using directive or an assembly reference?) (CS1061) (Assembly-CSharp)

Help would be very much appreciated,
Thanks.

 

That's because you're calling ".transform" on the entire array of items. You should instead loop over each item in the array and do it individually.

 

Like so:

If you're just checking hitColliderObject, you can use a foreach loop:

Code (CSharp):

1. Collider[] hitColliders = Physics.OverlapSphere(center, explosionRadius);
2.  
3. foreach(Collider hitCollider in hitColliders){
4.      GameObject hitColliderObject = hitCollider.transform.parent.gameObject;
5.      //Do some stuff here
6. }

But, if you're going to be changing hitColliderObject in any way, you'll need a for loop:

Code (CSharp):

1. Collider[] hitColliders = Physics.OverlapSphere(center, explosionRadius);
2.  
3. for(int i = 0; i < hitColliders.Length; i++)){
4.      Collider hitCollider = hitColliders[i];
5.      GameObject hitColliderObject = hitCollider.transform.parent.gameObject;
6.      //Do some stuff here
7. }
