Sorting Collider Arrays by location of elements

Hello everyone,
I am trying to sort an Array of Colliders which I get the following way:

Collider[] hitColliders = Physics.OverlapSphere(l_handBase.transform.localPosition, 2.0f, 9);

This returns me colliders, from which I then need to sort the x position of the parent of the transform of the collider.

Explanation (not actually valid code):

for( int i=0 ; i<hitColliders.Length ; i++ )
    hitColliders[i].transform.parent.localPosition.x

I need to sort the colliders by the x values of the localPosition, I don’t think I can just use a float List, since I wouldn’t be able to access the colliders directly anymore.

Any help would be greatly appreciated!

Hey, dude… I literally just got this ^^

You must use this on your code:

using System.Linq;

then use:

Collider[] colliders = Physics.OverlapSphere( overlapSphereCenter , 2.0f , 9 );
Vector3 sortingOrigin = transform.position;
colliders.OrderBy( col => Vector3.Distance(sortingOrigin,col.transform.position) );

Hi, I know this is old, but just in case someone stumbles upon this when searching for a solution like me :slight_smile:

I tried using @Estevominador answer, but I got an exception:

At least one object must implement IComparable

I initially thought this was because Collider didn’t implement the comparable interface, but in fact it was because ColliderDistance does not (this is the object that the method .Distance() returns).

So if you want to order an array or list of colliders, you can use this:

using System.Linq;
var colliders = Physics.OverlapSphere(center, radius);
var orderedByProximity = colliders.OrderBy(c => (center - c.transform.position).sqrMagnitude).ToArray();

I found this solution by @derHugo on StackOverflow:

Hope it helps anyone, since this was the first post that came up when searching on google :smiley:
