Checking Object Collision Without Script

Question

Is there a way to check if an object is colliding with something without having a script on that particular object. Like so:

 Transform other = null;
 
 void Update () {
 
    if(other.collider.isColliding){
         //Rest of code in here
    }
 }

Is there a way to do that? Or would I have to put a script on that object and use OnCollisionEnter()?

Take a look at the Physics class. They have several methods that will allow you to make tests: OverlapShpere(), CapsulCast(), SphereCast(), CheckSphere() and the like that allow you to test for colliders in a particular area.

Yeah, but I was thinking that would kill the fps. What would be better though? A script using only OnCollisionEnter on 200+ objects, or using a SphereCast() on all of them?
