Automate Component Setup with Reset() and [RequireComponent]

The Tip: Manually configuring required component dependencies or default parameters across prefabs causes setup mistakes.

How to Use: Combine [RequireComponent] with Unity's built-in Reset() event callback. Reset() runs automatically when attached or reset in the Inspector.

using UnityEngine;

[RequireComponent(typeof(CircleCollider2D))]
public class TriggerArea : MonoBehaviour
{
    private void Reset()
    {
        var col = GetComponent<CircleCollider2D>();
        col.isTrigger = true;
        col.radius = 2.5f;
    }
}
