using UnityEngine;

//Always attach a SphereCollider component to your GameObject public class Example : MonoBehaviour { //This declares your SphereCollider SphereCollider myCollider;

void Start() { //Assigns the attached SphereCollider to myCollider myCollider = GetComponent<SphereCollider>(); }

void OnTriggerEnter(Collider other) { //This increases the Collider radius when the GameObject collides with a trigger Collider myCollider.radius += 2f; } }
